Representative Morgan Griffith (R-VA) has introduced two bills that would remove federal roadblocks to marihuana and cannabidiol (“CBD”) access by patients for legitimate medical purposes in states that allow such access. (We use the spelling of “marihuana” that appears in the federal Controlled Substances Act (“CSA”) and the bills). Congressman Griffith sponsored the “Legitimate Use of Medicinal Marihuana Act,” H.R. 714, and reaching across the aisle, co-sponsored the “Compassionate Access Act,” H.R. 715, with Earl Blumenauer (D-OR). The Oregon representative has advocated to remove marihuana from control under the CSA. An accompanying press release notes that the current bills “would alleviate” CSA blockage of measures that permit the use of marihuana for treating cancer and glaucoma passed by Virginia, Congressman Griffith’s state, in 1979.

The Compassionate Access Act (“CAA”) and the Legitimate Use of Medicinal Marihuana Act (“LUMMA”) are the latest proposals to change Federal law and authorize the medical use of marihuana. We note that most recently in November, voters in Arkansas, Florida and North Dakota approved marihuana for medical use, joining a growing majority of states that authorize the use of marihuana or low-THC oil (“CBD”) for medical purposes. These bills are also a response to the Drug Enforcement Administration’s (“DEA’s”) August 2016 denial of two petitions to reschedule marihuana wherein DEA and the Department of Health and Human Services (“HHS”) have maintained the status quo, that is, that marihuana lacks a currently accepted medical use in treatment in the United States. We posted a blog on the petition denials on August 24, 2016.

In short, both bills as drafted appear to conflict with existing administrative and statutory requirements, particularly, the requirement that marihuana (or any other controlled substance) cannot be rescheduled from Schedule I without a finding of currently accepted medical use.

A drug can be scheduled, rescheduled or de-scheduled through administrative rulemaking or Congress can take such action by legislation. The CAA appears to mandate that HHS and DEA administratively reschedule the drug, and the LUMMA, would reschedule the drug by legislation. However, both approaches as drafted, have some serious faults. First, the CAA would require that HHS and DEA conduct administrative rescheduling but arrive at a specific result whether or not supported by the scientific and medical evaluation that is required under such action. Second, the LUMMA would reschedule marihuana by legislation but does not specifically find that Congress has determined that marihuana has a currently accepted medical use in the United States. Thus, the LUMMA would run afoul of the existing statutory criteria for placing drug in Schedule II-V. Congress has legislatively scheduled drugs in the past, e.g., anabolic steroids, however we are unaware of any case where Congress has rescheduled a drug from Schedule I into another schedule which would authorize its legitimate medical use.

The following is a brief summary of the proposed bills:

The Compassionate Access Act

The CAA would require HHS within 180 days, in consultation with the Institute of Medicine of the National Academy of Sciences, to recommend that DEA reschedule marihuana from Schedule I to another schedule. And DEA, “taking into consideration” HHS’ recommendation, would have one year to issue a final rule rescheduling marihuana. The CAA would also remove CBD from the CSA’s definition of marihuana and separately define it as a derivative from marihuana or synthetically formulated with 0.3 percent delta-9-tetrahydrocannabinol (“THC”). DEA considers all extracts of marihuana including CBD to be Schedule I substances.

The CAA mandate that HHS recommend rescheduling, and that DEA reschedule it, appears to disregard the existing CSA requirement that HHS and DEA conduct a medical and scientific evaluation, the “eight factor analysis.” The CAA’s removal of CBD containing trace amounts of THC from the definition marihuana seems more reasonable considering that consumption of CBD reportedly does not produce psychoactive effects and thus lacks potential for abuse, a key criteria for placement in any schedule.

In addition, the CAA would prohibit the CSA and the Federal Food, Drug and Cosmetic Act (“FDCA”) from restricting activities in states that have authorized marihuana and CBD activities for medical use, including:

• “[T]he prescription of marihuana;”
• “[A]uthorized patients” to obtain, possess, transport and use marihuana;
• Caregivers to obtain, possess and transport marihuana for authorized patients;
• Parents or guardians to obtain, possess and transport marihuana for minors;
• Production, processing, manufacturing and distributing marihuana;
• Pharmacies and health care providers dispensing marihuana; and
• Laboratories testing safety, quality and efficacy of marihuana.

However, the CAA does not specifically amend the CSA nor create a statutory scheme to resolve the internal conflicts with existing provisions of the CSA. So, unless, marihuana was rescheduled, these requirements would be inconsistent with the law and regulations.   The CAA would lift the same CSA prohibitions that apply to CBD activities in those states where authorized.

Lastly, the CAA mandates that the Attorney General “delegate responsibility . . . for control over access to marihuana for research into its potential medicinal uses to an agency of the executive branch that is not focused on researching the addictive properties of substances.” The goal is for the agency assuming such responsibility is to ensure the availability of an adequate supply of marihuana for medicinal research.

We are unsure how the Attorney General would delegate authority provided by the CSA to ensure access to marihuana for research to another agency outside the Department of Justice. However, that said, this provision may not be as necessary as intended given that DEA has now abrogated its long-held policy of limiting marihuana cultivation for research to a single grower. DEA recognizes the need to increase the number of marihuana cultivators for product development, explaining that the prior monopoly was for federally-funded and academic research. DEA’s decision to issue additional marihuana manufacturer registrations for supplying researchers may make the provision requiring delegation of responsibility over access to marihuana for research unnecessary.

The Legitimate Use of Medicinal Marihuana Act

The LUMMA mirrors the CAA in certain respects, but there are some notable differences. For example, while the CAA would require administrative rescheduling of marihuana to any schedule other than Schedule I, the LUMMA would move marihuana specifically to Schedule II.

While it is necessary to resolve the current myriad of conflicting state marihuana and CBD approvals with federal restrictions, these bills are not the vehicles to do it.

The CAA was introduced and referred to the House Committee on Energy and Commerce and the House Judiciary Committee on January 27th. The LUMMA was introduced on the same day and referred to the House Committee on Energy and Commerce.

It is often said that companies have an absolute right to petition the government to take or not take action without fearing exposure to an antitrust suit.  This “right” is thought to be based on a series of Supreme Court decisions that are collectively commonly referred to as the “Noerr-Pennington doctrine.”  In fact, this “right” is not an absolute right, particularly in the context of Citizen Petitions filed with FDA.  A lawsuit filed and announced on February 7, 2017 demonstrates that the government can, and in appropriate cases will, take enforcement actions against companies that file what the government believes are sham Citizen Petitions.  This lawsuit thus serves as a warning that the government is concerned about the misuse of FDA’s Citizen Petition process.

The lawsuit in question was filed by the Federal Trade Commission (“FTC”) in the U.S. District Court for the District of Delaware and is styled as a Complaint for Injunctive and Other Equitable Relief.  The FTC alleges that ViroPharma Inc. (“ViroPharma”), before it was acquired by another company, abused FDA’s Citizen Petition process in violation of Section 5(a) of the FTC Act (15 U.S.C. § 45(a)) when ViroPharma used that process to petition FDA not to approve ANDAs for generic versions of VANCOCIN (vancomycin HCl) Capsules (approved under NDA No. 050606). The FTC had been investigating ViroPharma’s VANCOCIN petitioning activities for quite some time (see here and here).

“Facing the threat of generic competition to its lucrative franchise, ViroPharma inundated the FDA with regulatory and court filings—forty-six in all—to delay the FDA’s approval of generic Vancocin Capsules. That number is, by far, the most filings that any firm has ever made to the FDA concerning a single drug product,” writes the FTC in its Complaint.  “These repetitive, serial, and meritless filings lacked any supporting clinical data, which ViroPharma understood it needed to have any chance of persuading the FDA of its positions.  Even after a panel of sixteen independent experts unanimously rejected its unsupported claims in August 2009, ViroPharma continued its petitioning campaign to obstruct and delay the FDA’s generic approval review process.”  Although “FDA disposed of ViroPharma’s challenges as being ‘unsupported’ and ‘lack[ing] merit,’” in a Citizen Petition Response, “by that point, ViroPharma’s campaign had succeeded in delaying generic entry at a cost of hundreds of millions of dollars to patients and other purchasers,” says the FTC.

As readers of this blog might recall, ViroPharma’s petitioning activity resulted in what might be the longest Citizen Petition response of all-time: a monster 87-page response from FDA in April 2012 (see our previous post here).  A ViroPharma lawsuit against FDA followed (see our previous posts here and here), where the company was ultimately unsuccessful in challenging FDA’s bioequivalence requirements for generic VANCOCIN, as well as FDA’s denial of 3-year exclusivity for a VANCOCIN Supplement NDA the Agency approved on December 14, 2011. (Our firm represented ANDA applicant and intervenor Akorn in that lawsuit.) (We also note that ViroPharma found itself embroiled in years-long class action securities litigation after making certain statements about the prospect of FDA granting a period of 3-year exclusivity.)

Although there’s a lot that’s interesting in FDA’s Citizen Petition Response (Docket No. FDA-2006-P-0007), what’s particularly interesting for our purposes here is FDA’s admonition of ViroPharma’s petitioning activity. FDA comments as follows on pages 74-75 of the response:

FDA notes that you have petitioned FDA in a fashion analogous to interrogatories in civil discovery, demanding answers to more than 170 individual factual questions related to the Agency’s development of the vancomycin bioequivalence recommendation. This is an improper use of the citizen petition process.  The petition procedure enables parties to “petition the Commissioner to issue, amend, or revoke a regulation or order, or to take or refrain from taking any other form of administrative action.”  “Administrative action” is defined in relevant part as “every act, including the refusal or failure to act, involved in the administration of any law by the Commissioner.”  The “action” you request the Agency to take here – to respond directly to factual questions regarding certain Agency decisions – is secondary to your underlying challenge of those decisions.  In the interest of a thorough evaluation of the many issues you raise, however, FDA has incorporated these questions and the events referenced therein in its consideration of your petition.

Since then, we’ve seen other (and bolder) admonitions from FDA over a company’s petitioning activity, and even referrals to the FTC to investigate a company’s petitioning activity. For example, in a February 2013 denial of a September 2012 505(q) Citizen Petition (Docket No. FDA-2012-P-1028) concerning the approval of generic Buprenorphine drug products, FDA said that the Agency “referred this matter to the Federal Trade Commission, which has the administrative tools and the expertise to investigate and address anticompetitive business practices.”  Also, in an August 2013 denial of a March 2013 Citizen Petition (Docket No. FDA-2013-P-0247) concerning the approval of generic Zoledronic Acid Injection, in a section titled “Misuse of Petition Process,” FDA comments: “This Petition represents a particularly egregious misuse of the FDA citizen petition process for what appears to be the purpose of delaying generic competition.”  Most recently, in a January 2017 denial of a December 2016 505(q) Citizen Petition (Docket No. FDA-2016-P-4585) concerning FDA’s approval of generic versions of AMPYRA (dalfampridine) Extended-release Tablets, FDA comments, in part, in a section titled “Timing of the Petition” that:

As stated in FDA’s annual report to Congress required under section 505(q)(3) of the FD&C Act, FDA continues to be concerned that section 505(q) is not discouraging the submission of petitions that are intended primarily to delay the approval of competing drug products. This Petition was submitted on December 26, 2016, seventeen business days before the expiration of orphan-drug exclusivity associated with Ampyra, on January 22, 2017 (i.e., the earliest date on which ANDAs referencing Ampyra could be approved, provided that all other applicable requirements for approval are met). . . .  In short, under these circumstances, this Petition was submitted inappropriately close to the date of expiry of Ampyra’s orphan-drug exclusivity and the date on which ANDAs referencing Ampyra would become eligible for approval.

The FTC, in its Complaint against ViroPharma, paints quite the picture of alleged obstructionism, with a litany of actions and lawsuits that the FTC says “harmed competition and consumer welfare”:

Between March 2006 and April 2012, ViroPharma made at least forty-three submissions to the FDA and initiated three more proceedings in federal court to obstruct and delay the FDA’s approval of generic Vancocin Capsules, including:

• Twenty-four citizen petition filings submitted to the FDA;
• Seventeen public comments submitted to the FDA regarding the FDA’s in vitro dissolution guidance for generic Vancocin Capsules;
• A public comment submitted to the FDA regarding the FDA’s process related to publishing bioequivalence guidances;
• An sNDA for Vancocin Capsules claiming a three-year marketing exclusivity;
• A lawsuit challenging the FDA’s document production in response to ViroPharma’s Freedom of Information Act document requests;
• A lawsuit challenging the FDA’s in vitro dissolution guidance for another generic drug; and
• A lawsuit challenging the FDA’s response to ViroPharma’s Citizen Petition and related amendments and supplements, and the FDA’s approval of generic Vancocin Capsules.

The FTC is seeking declaratory and injunctive relief, including “a court order permanently prohibiting ViroPharma from submitting repetitive and baseless filings with FDA and the courts, and from similar and related conduct as well as any other necessary equitable relief, including restitution and disgorgement.”

The FTC’s action against ViroPharma is not the first to challenge a company’s petitioning activity as anticompetitive.  Over the years we’ve seen several lawsuits (usually from direct or indirect purchasers).  You can read up on some of those lawsuits in articles here and here, as well as in our previous posts here and here.

Just before President Trump took office, FDA issued a series of documents detailing how it would regulate the products of gene editing. Specifically, FDA issued policy statements in the form of an announcement on its website and an article in the FDA Voice, FDA’s official blog.  FDA also issued two draft guidance documents and accompanying documents.  Those draft guidance documents cover FDA regulation of animals whose genomic DNA have been intentionally altered (the draft guidance can be found here, as well as a Q&A document) and the scope of FDA’s authority over mosquito-related products (the draft guidance can be found here).

These documents continue the series of recent efforts to clarify how the Federal government intends to regulate 21st-century biotechnology.  The documents fall in line with the September release of the National Strategy for Modernizing the Regulatory System for Biotechnology Products (a copy of which can be found here) as well as the more recently released update to the Coordinated Framework for the Regulation of Biotechnology (a copy of which can be found here on our website now that the Trump Administration has, at least for now, removed it from the White House website where it used to be found).

Although the series of documents were highly anticipated and some had hoped for a change to the regulatory approaches that have been in place for over a decade, we find that little is changed from how FDA has approached these products in the recent past. So, while it is helpful to have greater clarity around these issues, one word sums up our overall impression: meh.

Regulation of Genetically Engineered Animals

It has been eight years when FDA’s Center for Veterinary Medicine (“CVM”) issued its final guidance regarding the regulation of animals that have been genetically engineered via recombinant DNA (“rDNA”) technology. For those who live or work in the Washington area, it should come as no surprise that the final of the original guidance was issued on the last working day of the George W. Bush administration and that this update should be issued, if only in draft form, on the last working day of the Obama administration.  The issue of genetically engineered (“GE”) animals has been highly controversial both inside and outside of The Beltway (see our prior post discussing Congressional activity on the subject, here, as well as lawsuits challenging FDA’s authority in this area, here).

The most significant substantive change to the draft guidance from the prior final version of the guidance is that the draft guidance explicitly includes all animals whose genomes have been intentionally altered, no matter how the alternation occurred. The prior version, on its face, was limited to animals genetically engineered by rDNA technology.  Newer biotechnologies, such as the CRISPR/Cas system (see discussion of these technologies here), do not necessarily use rDNA technology, and some companies and academics have argued that these “genome editing” technologies fall outside the scope of FDA guidance and FDA’s authority.  Since at least 2015, however, CVM has been publicly stated that all genome editing techniques met the statutory definition of a new animal drug and, therefore, were under FDA’s statutory authority (see, for example, CVM’s presentation to the National Academy of Sciences’ Roundtable on Science and Welfare in Laboratory Animal Use, here).  So, objections regarding FDA’s revisions in the draft guidance are a bit late to the party.  Setting aside potential issues of podium policymaking, the draft guidance merely clarifies and properly issues a statement of FDA’s pre-existing policies.

When issuing the draft guidance, FDA asked in its Notice of Availability for public comment not only on the document itself, but specifically with respect to two questions:

1. How to refer to the animals subject to the draft gudiance. In the past, FDA has used the term “genetically engineered” to refer to animals containing recombinant DNA constructs intended to alter the structure or function of the body of the animal. In the draft guidance, CVM uses the phrase “animals whose genomes have been altered intentionally.” In the opinion of your author, this term is clunky, and unnecessarily confusing. From a scientific perspective, all such animals are genetically engineered – after all, there genetics have been changed by design, which seems to be the very definition of genetic engineering.  CVM asks the public to weigh in on this definitional issue.
2. Whether there is any existing empirical evidence demonstrating that certain types of genome editing may pose minimal risk, and not require the type of regulatory oversight contemplated by the draft guidance. This could include categories of animals or types of genetic changes that are likely to pose minimal risks to the animal, to food safety concerns, or to the human environment.

Comments on the draft guidance should be submitted by April 19th.

Regulation of Mosquito-Related Products

The other draft guidance that FDA issued discussed when mosquito-related products would be regulated by FDA under the FDCA and when products would be regulated by EPA under the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”). The draft guidance does not change the existing regulatory jurisdiction of either agency, but rather clarifies for companies which agency will take jurisdiction under which circumstances.

In brief, CVM does not consider mosquito-related products as new animal drugs when those products are intended to function as pesticides by preventing, destroying, repelling, or mitigating mosquitoes for population control purposes. Accordingly, such products would be regulated by EPA under FIFRA.  All mosquito-related products that are intended to prevent, treat, mitigate, or cure disease in animals or man that do not function as pesticides will be regulated by FDA as drugs.

Comments on this mosquito-related products draft guidance should be submitted by February 21st.

With all the uncertainty that exists with any new Administration, one thing in the area of genome editing is certain – the federal government will continue to seek to regulate this technology. All parties, even if they agree with the draft guidance documents, are encouraged to submit comments to FDA expressing their views.

Earlier this month, FDA published much-needed draft guidance on 180-day exclusivity, titled “180-Day Exclusivity: Questions and Answers.”  We perused the document and promptly posted on it the next day, noting, among other things, that the draft guidance doesn’t reveal anything revolutionary, but rather,  provides a one-stop shop reference on 180-day exclusivity insofar as it consolidates court cases and documents released in litigation, letter decisions, citizen petition responses, and other correspondence to provide answers to commonly asked questions.  Since then, we’ve had some time to dig into the draft guidance, and we found two points in particular worth noting.  The points aren’t new insofar as they reflect newfound FDA interpretations; however, it later occurred to us that these points reflect decisions previously made by FDA of which we’ve had some awareness, but that haven’t yet been made public in an FDA letter or approval decision.

Both points concern the so-called failure-to-market forfeiture provision at FDC Act § 505(j)(5)(D)(i)(I) – and the “(bb) bookend event” in particular – and both points are embedded in FDA’s response to Question 24 in the draft guidance (on pages 15-17): “Q24. How does FDA determine whether a first applicant has forfeited exclusivity under the “failure to market” provision?”  The first point is made in four short words in line 585 of the draft guidance: “the same other applicant.”  The second point is made in a hypothetical forfeiture analysis on page 16 of the draft guidance where the key words are “received tentative approval at some point.”

By way of background, the FDC Act provides that a first applicant’s eligibility for 180-day exclusivity may be forfeited if the first applicant fails to market the drug by the later of two “bookend” dates. The first date is the earlier of 75 days after final approval of the first applicant’s ANDA and 30 months after the date of submission of the first applicant’s ANDA.  The second date is calculated 75 days after a final court decision.  Specifically, the statute provides:

(bb) with respect to the first applicant or any other applicant (which other applicant has received tentative approval), the date that is 75 days after the date as of which, as to each of the patents with respect to which the first applicant submitted and lawfully maintained a certification qualifying the first applicant for the 180-day exclusivity period under subparagraph (B)(iv), at least 1 of the following has occurred:

(AA) In an infringement action brought against that applicant with respect to the patent or in a declaratory judgment action brought by that applicant with respect to the patent, a court enters a final decision from which no appeal (other than a petition to the Supreme Court for a writ of certiorari) has been or can be taken that the patent is invalid or not infringed.

(BB) In an infringement action or a declaratory judgment action described in [FDC Act § 505(j)(5)(D)(i)(I)(bb)(AA)], a court signs a settlement order or consent decree that enters a final judgment that includes a finding that the patent is invalid or not infringed.

(CC) The patent information submitted under [FDC Act § 505(b) or (c)] is withdrawn by the holder of the application approved under subsection (b).

With that, let’s turn to point 1: whether FDC Act § 505(j)(5)(D)(i)(I)(bb) permits a “mix-and-match” approach in addition to an “all-in-one” approach. Under the “all-in-one” approach, the parenthetical “(which other applicant has received tentative approval)” provides that the 75-day period is triggered when the same subsequent applicant has both tentative approval and a final court decision that the relevant patent is invalid or not infringed.  Under the “mix-and-match” approach, the parenthetical allows different subsequent ANDA applicants to have tentative approval and a final court decision.

FDA has already faced this scenario in a couple of instances, and has determined that the “all-in-one” approach is the way to go. FDA conveys this in the draft guidance in a sentence stating: “For an event to occur under item (bb) by any other applicant, the same other applicant must receive both tentative approval and a final court decision described in subitem (AA) or (BB)” (emphasis added).

Moving on to point two – whether the order in which an other applicant obtains a court decision and tentative approval counts – FDA answers this question in the following hypothetical:

A hypothetical example illustrates how FDA determines whether forfeiture has occurred under the “failure to market” provision. For the purposes of evaluating item (aa), presume that on June 1, 2009, the applicant for ANDA A submitted its substantially complete application containing a paragraph IV certification, which it lawfully maintained.  FDA approved the ANDA on December 20, 2012, and the 75-day period identified in subitem (AA) of this forfeiture provision ended on March 4, 2013.  Thirty months after the date the ANDA is submitted was December 1, 2011 (the date identified in subitem (BB)).  The relevant date for item (aa) of the forfeiture analysis is December 1, 2011, the earlier of these two dates.

For the second part of the analysis under item (bb), presume that on January 1, 2013, a court entered a final decision (from which no appeal (other than a petition to the Supreme Court for a writ of certiorari) has been or can be taken) that the relevant patent is invalid and not infringed in an infringement action against a subsequent applicant for this RLD whose ANDA received tentative approval at some point before FDA makes the forfeiture determination.  The relevant forfeiture date for ANDA A pursuant to subitem (AA) is March 17, 2013, 75 days after the date on which the court issued its decision.  Notably, this date applies even though ANDA A in this example was not the subject of the litigation.

In this scenario, the failure to market forfeiture provision requires the first applicant to market by March 17, 2013, the later of the dates applicable under item (aa) (December 1, 2011) and item (bb) (March 17, 2013). In this example, if ANDA A applicant did not begin commercial marketing until after March 17, 2013, it would forfeit its exclusivity.  [(Emphasis added)]

In this hypothetical, FDA not only repeats (inherently) the “all-in-one” approach, but also clarifies, in the highlighted language above, that a relevant court decision triggers the 75-day period once tentative approval is obtained, even if that tentative approval is later obtained by the same applicant. Thus, it is not the completion of the two events – tentative approval and a court decision – that triggers the 75-day countdown (unless the tentative approval comes before the court decision), but the court decision that is solely relevant.  So, a later-obtained tentative approval makes a previously-obtained court decision (by the same applicant) operative, such that if tentative approval is obtained one year after the court decision, 180-day exclusivity is forfeited retroactively (absent any commercial marketing by the first applicant).

We imagine there was more language concerning the points above – as well as other forfeiture-related items/provisions – in FDA’s internal draft versions of the guidance document, and that a lot of text was left on the cutting room floor.

One item we hoped the draft guidance would cover explicitly but doesn’t appear to is whether the so-called “change-based exception” under the failure-to-obtain-timely-tentative-approval forfeiture provision at FDC Act § 505(j)(5)(D)(i)(IV), when it is invoked, means that there is no deadline to obtain tentative approval or else forfeit exclusivity. This blogger thinks most folks would agree that the change-based exception is truly that: a provision that, when it applies, means that FDC Act § 505(j)(5)(D)(i)(IV) is no longer relevant to a forfeiture determination. But at least one court, in an antitrust action, has determined otherwise, stating: “It makes sense to read the Change-Based Exception as an extension, not an obliteration, of the 30-month deadline” (see here, here, and here).

As previously reported, on May 1, 2015, FDA issued a proposal to amend the 1994 Tentative Final Monograph (TFM) for the over-the counter (OTC) health care antiseptic drug products, including health care personnel hand washes, health care personnel hand rubs, surgical hand scrubs, surgical hand rubs, and patient preoperative skin preparations.  FDA proposed to classify all active ingredients as category III because of missing information on all ingredients. In light of scientific developments since 1994, FDA proposed to require additional safety data to support the safety of antiseptic active ingredients. FDA further proposed to require that all health care antiseptic active ingredients have in vitro data characterizing the ingredients’ antimicrobial properties and in vivo clinical simulation studies.  The proposed rule identified data gaps for 11 of the 28 active ingredients that had been considered in the rulemaking for health care antiseptics.

FDA acknowledged that the proposed rule was complex. Moreover, the Agency indicated that it would consider requests to defer further rulemaking for specific active ingredients to allow time for studies to address the data gaps.

True to its word, on January 19, 2017, FDA posted letters in the docket deferring rulemaking on a number of active ingredients, namely

• Povidone-Iodine
• Isopropyl Alcohol
• Benzalkonium Chloride
• Benzethonium Chloride
• Chloroxylenol
• Ethyl Alcohol

For each of these ingredients, FDA has agreed to defer rulemaking initially for one year, with the possibility of an extension/renewal. The deferrals are conditioned on the parties’ initiation of studies. If FDA determines that no studies have been commenced or that the studies are not productive, it will proceed to rulemaking after the initial deferral. Parties that have been granted the deferrals are required to submit “clear statements of [their] intent to conduct all necessary studies with proposed timelines, as described in [their] letter, and submit full study reports to the public docket.” Each letter specifies the studies that FDA requires for the active ingredient. Further, all letters provide a timeline for the parties (e.g., parties must acknowledge receipt of the letter and submit a statement of intent within 60 days of receipt of the letter; they must submit a study plan within six months of receipt of the letter, submit reports at a specific time etc., etc.).

No deferrals were granted for the other five active ingredients discussed in the proposed rule, hexylresorcinol, iodine tincture, iodine topical solution USP, triclosan, and tricarbon. Presumably, FDA will complete rule making for these ingredients in accordance with the timeline mandated by the consent decree (requiring publication of a final rule by January 15, 2018).

Earlier this week, Representatives Gus Bilirakis (R-FL) and Kurt Schrader (D-OR) announced the introduction of H.R. 749, the Lower Drug Costs Through Competition Act.  The bill, which appears to be nearly identical to H.R. 4784 introduced in March 2016, is intended “to lower the cost of prescription drugs by increasing competition in the market,” according to a press release.

Specifically, Title I of H.R. 749 would amend the FDC Act to add Section 505(j)(11), stating:

(A) The Secretary shall prioritize the review, and act not later than 180 calendar days after the date of the submission of an application, on an application that has been submitted and accepted for review under this subsection, or on a supplement to such an application, that is for a drug that—

(i) has been introduced into interstate commerce by not more than one manufacturer or sponsor, as applicable, in the last 3 months and with respect to which tentative approval under paragraph (5) has been granted for not more than 2 applications; or

(ii) has been included on the [drug shortage] list under section 506E.

(B) The Secretary may expedite an inspection or reinspection under section 704 of an establishment that proposes to manufacture a drug described in subparagraph (A).

The 6-month (180-day) FDA review period provided for above is not much different than the 8-month review and action goal for certain Priority Original ANDAs identified in the GDUFA II Proposed Commitment Letter, and is even longer than the 4-month review and action goal proposed under GDUFA II for certain Priority PASs.

Title II – “Incentivizing Competition” – of the “Lower Drug Costs” is interesting. It would create a Priority Review Voucher (“PRV”) for ANDAs – a “Generic PRV” – allowing for review and action on an ANDA “not later than 180 calendar days after such application has been submitted and accepted for review” (emphasis added).  Of course, if the 180 days does not begin until after both submission and acceptance of an ANDA (which acceptance could be 30 days, 60 days, or more after initial submission of an ANDA), then there doesn’t really seem to be much of a benefit to obtaining and using a Generic PRV, particularly given the proposed GDUFA II goals.  In any case, like other PRVs, a Generic PRV would be transferable, would require pre-use notice to FDA, and would be subject to a special priority review user fee set by FDA each fiscal year.

Although another version of the bill was introduced in Spring 2016, H.R. 749 appears, in one sense, to build on legislation introduced in the U.S. Senate at the tail end of the 114th Congress – S. 3387, the Safely Advancing Valuable and Inexpensive New Generic Solutions Act, or “SAVINGS Act” – which sought the creation of a statutory expedited review mechanism for ANDAs for certain drug products without generic competition and in shortage.  But, as noted above, the Lower Drug Costs bill goes further.  The bill continues a recent trend that seems to generally favor the creation of PRVs (as well as new tax credits) over new or extended periods of marketing exclusivity (see our previous posts here, here, and here).  (Although we note that Section 5001 of a Discussion Draft of the 21st Century Cures Act would have extended 180-day generic drug exclusivity and interchangeable biosimilar exclusivity by an undefined amount of time for “American-manufactured” products – see our previous post here.)

There are two additional noteworthy provisions in H.R. 749. First, the bill would amend the Tropical Disease PRV provisions at FDC Act § 524(a)(4)(A) concerning what constitutes a “tropical disease product application.”  The bill would add the requirement that such application contain “reports of new clinical investigations (other than bioavailability studies) essential to the approval of the application and conducted or sponsored by the applicant.”  This could limit the number of Tropical Disease PRVs handed out by FDA, as NDA sponsors would need to conduct or sponsor studies, instead of, for example, relying on published literature reports of studies.

Second, H.R. 749 requires, in Title III, that the Comptroller General conduct a study on Risk Evaluation and Mitigation Strategies (“REMS”). Among other things, the study would examine “[t]he effect of REMS programs and additional risk mitigation strategies, including non-REMS restricted distribution systems, on generic entry into the marketplace” and on drug prices.

Last week, just before the new Orange Book (print and electronic versions) made its debut, we opined (see our previous post here) that changes to the Orange Book Preface would likely be made. Now that the print version of the Orange Book is available (here), we’ve had a chance to peruse those Preface (and Patent and Exclusivity Information Addendum) revisions.  Although the changes made to the 2017 Orange Book Preface are not nearly as substantial as the 2016 facelift (see our previous post here), there are some noteworthy changes, which we highlight below.  For ease of use and reference, we put together a redline of the 2017 Orange Book Preface and Patent and Exclusivity Information Addendum showing the additions and deletions compared to the 2016 versions.

Orange Book Preface

• Right off the bat, FDA deletes from the 2017 Preface any specific reference to drug products subject to pending DESI proceedings. Now gone is the text stating “Drugs on the market approved only on the basis of safety (covered by the ongoing Drug Efficacy Study Implementation [DESI] review [e.g., Donnatal® Tablets and Librax® Capsules] or pre-1938 drugs [e.g., Phenobarbital Tablets]) are not included in this publication.” We anticipated that FDA would remove any reference to Librax, given the recent discovery that the drug was approved in the mid-1960s (see our previous post here); however, we didn’t expect the deletion of all that DESI-related and grandfather drug information. Now such products truly “are not included in this publication.”
• In Section 1.2 (Therapeutic Equivalence-Related Terms) of the Preface, FDA clarifies certain common terms, such as “pharmaceutical equivalents” and, in particular, “strength” to comport with definitions (at 21 C.F.R. § 314.3) that became effective on December 5, 2016 with the implementation of certain provisions of the 2003 Medicare Modernization Act (“MMA”).
• Curiously, FDA, in a discussion of the term “therapeutic equivalents” in Section 1.2, deletes the following sentence:“Therapeutic equivalence determinations are not made for unapproved, off-label uses.” This sentence has appeared in the Preface since the 17th (1997) edition of the publication, and was likely added to the Orange Book Preface as a result of the U.S. Court of Appeals for the District of Columbia Circuit’s August 1996 decision in Bristol-Myers Squibb v. Shalala, 91 F.3d 1493 (D.C. Cir. 1996) (here). That decision affirmed an ANDA applicant’s ability to omit patent- or exclusivity- protected labeling information in a manner consistent with the FDC Act’s “same labeling” requirement. In reaching its decision, the D.C. Circuit ruled that the FDC Act “expresses the legislature’s concern that the new generic be safe and effective for each indication that will appear on its label; whether the label for the new generic lists every indication approved for the use of the pioneer is a matter of indifference.”
• In Section 1.4 (Reference Listed Drug and Reference Standard) of the Preface, FDA elucidates the terms “Reference Listed Drug” and “Reference Standard” and the process for their designation, as discussed in recent guidance issued by the Agency (see our previous post here).
• Fast-forwarding to Section 1.8 (Description of Certain Special Circumstances) of the Preface, FDA includes some added discussion around Levothyroxine Sodium and therapeutic equivalence ratings. In particular, FDA explains the rating of ANDA 076187 vis-à-vis other approved drug products and in light of a recent Citizen Petition decision (Docket No. FDA-2015-P-0403).

Orange Book Patent and Exclusivity Information Addendum

• FDA makes several noteworthy revisions to the Patent and Exclusivity Information Addendum, which precedes the Prescription and OTC Drug Product Patent and Exclusivity List. The changes reflect FDA’s new regulations implementing the MMA (e.g., patent information listings, and, in particular, method-of-use patent information), as well as new law, policy and court decisions.
• FDA’s descriptions of 5-year new chemical entity exclusivity and 3-year new clinical investigation exclusivity have been refined to reflect the Agency’s current interpretations of the law. For example, FDA’s revised description of 3-year exclusivity now states that if 3-year exclusivity is granted, then “a subsequent ANDA or a 505(b)(2) application may not be approved for the exclusivity-protected ‘conditions of approval of such drug’ before the expiration of three years from the date of approval of the original application. If a NDA or 505(b)(2) applicant has exclusivity only for a new indication or use, this exclusivity generally does not preclude the approval of an ANDA or 505(b)(2) application for indications and uses not covered by the exclusivity, assuming the proposed drug product will be safe and effective as labeled.” This revised description appears to be intended to more clearly convey FDA’s focus on the scope of 3-year exclusivity (see our previous posts here and here).
• FDA includes a note around the end of the Addendum stating: “Please note that the date of approval for an NDA for which FDA recommends controls under the Controlled Substances Act is the later of the date on the approval letter for the NDA or the date of issuance of the interim final rule controlling the drug (see section 505(x)(1) and (2) of the FD&C Act).” This note is consistent with changes FDA recently implemented in the Agency’s regulations defining the term “date of approval” (21 C.F.R. § 314.3). Those changes were necessary after the statute was amended in November 2015 by the IRTNMTA (Improving Regulatory Transparency for New Medical Therapies Act) to add FDC Act § 505(x) (see our previous post here). For an example of the IRTNMTA in action, check out NDA 205525 for SYNDROS (dronabinol oral solution), 5 mg/mL. FDA “approved” NDA 205525 on July 1, 2016; however, the drug product is not yet listed in the Orange Book as an approved drug.  Why?  Because SYNDROS is not yet truly approved for Orange Book listing purposes, as the scheduling of the product under the Controlled Substances Act is pending.

Well, there you have it: the 2017 Orange Book notes for junkies. We’ll surely revisit this post in 2018 when the 38th edition of the Orange Book is published.

In a Complaint filed on January 27, 2017 in the U.S. District Court for the District of Columbia, ANDA applicant Amneal Pharmaceuticals LLC (“Amneal”) alleges that FDA incorrectly ruled that Amneal forfeited eligibility for 180-day exclusivity for generic versions of NAMENDA XR (memantine HCl) Extended-release Capsules, 7 mg, 14 mg, 21 mg, and 28 mg. As such, Amneal seeks declaratory and injunctive relief, asking the  court to vacate FDA’s forfeiture determination, declare that Amneal has not forfeited 180-day exclusivity, and to enter an order vacating or setting aside FDA’s final approval of several ANDAs already approved for generic versions of NAMENDA XR.

The lawsuit involves forfeiture of 180-day exclusivity under FDC Act § 505(j)(5)(D)(i)(IV). That provision, added by the 2003 Medicare Modernization Act, states that 180-day exclusivity eligibility is forfeited if:

The first applicant fails to obtain tentative approval of the application within 30 months after the date on which the application is filed, unless the failure is caused by a change in or a review of the requirements for approval of the application imposed after the date on which the application is filed.  [(Emphasis added)]

The 2007 FDA Amendments Act (“FDAAA”) clarified FDC Act § 505(j)(5)(D)(i)(IV), such that if “approval of the [ANDA] was delayed because of a [citizen] petition, the 30-month period under such subsection is deemed to be extended by a period of time equal to the period beginning on the date on which the Secretary received the petition and ending on the date of final agency action on the petition (inclusive of such beginning and ending dates) . . . .” (FDC Act § 505(q)(1)(G)). The 2012 FDA Safety and Innovation Act (“FDASIA”) made further changes with respect to the application of FDC Act § 505(j)(5)(D)(i)(IV) to certain ANDAs (see our previous post here). Neither the FDAAA, nor the FDASIA provisions came into play with Amneal ANDA 205825, but we note them nevertheless.

What does come into play, however, is the causation clause under FDC Act § 505(j)(5)(D)(i)(IV). FDA’s position has been that even if one of the causes of failure to obtain tentative approval by the 30-month forfeiture date was a change in or a review of the requirements for approval imposed after the application was submitted, a first applicant will not forfeit eligibility notwithstanding that there may have been other causes for failure to obtain tentative approval by the 30-month forfeiture date that were not caused by a change in or review of the requirements for approval.  That is, to avoid forfeiture, an applicant need only show that acceptability of one aspect of its ANDA (e.g., chemistry, labeling, or bioequivalence) was delayed due, at least in part, to a change in or review of the requirements for approval, irrespective of what other elements may also have been outstanding at the 30-month date.  In other words, “but-for” causation is not required in order to qualify for the exception under FDC Act § 505(j)(5)(D)(i)(IV).  FDA’s position is that this interpretation best effectuates the policy embodied in the exception, insofar as it does not penalize first applicants for reviews of or changes in approval requirements imposed after their ANDAs are submitted that cause the failure to obtain approvals or tentative approvals within 30 months, and continues to incentivize applicants to challenge patents by preserving (in many instances) the opportunity to obtain 180-day exclusivity.  FDA recently reiterated this position in draft guidance on 180-day exclusivity (see our previous post here).

Amneal submitted ANDA 205825 to FDA on June 10, 2013 containing Paragraph IV certifications challenging certain patents listed in the Orange Book for NAMENDA XR. FDA initially Refused to Receive (“RTR”) the ANDA, but rescinded that RTR decision on February 18, 2014 and acknowledged receipt of ANDA 205825 as of the initial June 10, 2013 receipt date.  As a result, Amneal is a “first applicant” – and apparently the sole first applicant – eligible for 180-day exclusivity for generic NAMENDA XR.

Seven months after rescinding the RTR determination for ANDA 205825, FDA issued a Complete Response Letter refusing to approve the ANDA and raising several questions, including a request for data from the manufacture of a commercial size lot (batch). Amneal supplied that information to FDA approximately eight months later, and provided additional information in September 2015, just a few months before the December 10, 2015 30-month forfeiture date under FDC Act § 505(j)(5)(D)(i)(IV).  In October 2015, FDA issued an Import Alert against Amneal’s API manufacturer, necessitating a change in API supplier by Amneal, which Amneal proposed in November 2015.  After other back-and-forth with FDA, including a second Complete Response Letter dated December 7, 2015, the Agency finally approved Amneal ANDA 205825 on October 12, 2016. . . . as well as ANDAs from other, subsequent Paragraph IV ANDA applicants.

As to Amneal’s eligibility for 180-day exclusivity, the last sentence above says it all. FDA determined in a September 21, 2016 Memorandum to ANDA 205825, and later in a September 28, 2016 Letter Decision sent to counsel for Amneal, that Amneal forfeited eligibility for 180-day exclusivity.  According to FDA, Amneal failed to obtain timely tentative approval or ANDA approval by the forfeiture date (i.e., December 10, 2015), and such failure was not caused by a change in or review of the requirements for approval.

It’s the causality element that Amneal takes particular issue with in the company’s Complaint: “FDA should not impose forfeiture if, as a factual matter, there is any causal connection between the failure to obtain tentative approval and a change in or review of approval requirements for the application,” according to Amneal (emphasis in original). To that end, Amneal argues that FDA’s forfeiture decision violates the FDC Act and the Administrative Procedure Act and must be vacated and set aside for at least four reasons:

1. FDA’s application of an irrebuttable adverse presumption of no causation if the change in or review of the approval requirements is resolved as of the forfeiture date is contrary to the causation analysis required by the FDCA and is arbitrary and capricious;

2. FDA’s decision is not the product of reasoned decision making because it failed to provide an explanation for rejecting any causal connection between the 14-month delay resulting from FDA’s demand for commercial-scale batch information and Amneal’s ability to obtain timely tentative approval;

3. FDA’s conclusion that its demand for commercial-scale batch information was not a change in or review of approval requirements because FDA had not changed a secret, undisclosed policy is contrary to the FDCA and is arbitrary and capricious;

4. FDA failed to consider the impact, either alone or in the aggregate, of the months-long delay in deciding whether to receive Amneal’s ANDA. The delay in receipt was itself the product of a change in or review of approval requirements and should have been considered by FDA as a potential cause for the failure to timely obtain tentative approval. FDA should also have considered the delay in receipt in an analysis of the causal effect of FDA’s demand for commercial-scale information.

In addition to requesting that the court set aside current ANDA approvals and declare that Amneal has not forfeited 180-day exclusivity eligibility, Amneal also requests that the court preliminarily and permanently enjoin FDA from granting final approval to any ANDA, other than Amneal ANDA 205825, until the expiration of Amneal’s 180-day exclusivity.

FDA recently put forth its first interpretation of the Regenerative Advanced Therapy (“RAT”) designation program, which was established by section 3033 of the 21st Century Cures Act. Although it consists of just a few short paragraphs on FDA’s website (here), the guidance confirms that FDA will use its standard definitions found in its Expedited Programs Guidance for terms like “serious or life-threatening,” and it signals that FDA has begun the lengthy process of implementing the new designation program. For a healthy dose of nostalgia, recall a simpler time, when breakthrough therapy designation was the newest tool in FDA’s expedited programs kit (here).

Background

Section 3033 of the 21st Century Cures Act provides that a drug is eligible for RAT designation if:

• “(A) the drug is a regenerative medicine therapy [which] includes cell therapy, therapeutic tissue engineering products, human cell and tissue products, and combination products using any such therapies or products, except for those regulated solely under section 361 of the Public Health Service Act and part 1271 of title 21, Code of Federal Regulations;
• (B) the drug is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and
• (C) preliminary clinical evidence indicates that the drug has the potential to address unmet medical needs.”

FDA’s website clears up any potential confusion related to the “includes” clause in the first prong by stating that “regenerative medicine therapy . . . is defined as a cell therapy, therapeutic tissue engineering products, human cell and tissue products, and combination products using any such therapies or products, except for those regulated solely under section 361 of the Public Health Service Act and part 1271 of title 21, Code of Federal Regulations.” (Emphasis added.)

Given the definition of RAT, it’s useful to recall that, per 21 CFR 1271.10(a), 361 human cells, tissues, or cellular or tissue-based products (“HCT/Ps”):

• Are minimally manipulated;
• Are intended for homologous use (as reflected in labeling and advertising);
• Are not manufactured by combining cells or tissues with another article, except for water, crystalloids, or a sterilizing, preserving, or storage agent; and
• Do not have a systemic effect nor are they dependent upon the metabolic activity of living cells for their primary function, with certain limited exceptions.

If any of these requirements are not met, the HCT/P is still subject to regulation under 21 C.F.R. Part 1271, but in addition is likely subject to biologic, drug, or medical device regulation.

In practice, many of the HCT/Ps in regenerative medicine that do not qualify as 361 HCT/Ps are regulated as biologics subject to section 351 of the PHS Act and approved via a biologics license application (BLA). The BLA process is perhaps the most burdensome and lengthy premarket review process that FDA imposes. To address this, Congress created the RAT designation.

Evolving Definition of Regenerative Therapy

The definition of RAT established by 21st Century Cures is considerably broader than the one recently provided by FDA in a presentation on regenerative medicine and regulatory science. In a October 2016 presentation, FDA stated that regenerative medicine products are generally for repair, replacement, or regeneration and usually are a combination of a biological product with a medical device (e.g., a 3D, cell-scaffold product).

Instead of focusing on function, a la “repair, replacement, or regeneration,” the 21st Century Cures definition puts greater emphasis on product type (e.g., whether it is a therapeutic engineering product), as opposed to intended use. After all, a RAT need only be “intended to treat . . . a serious or life-threatening disease or condition.” (Emphasis added.) This intended use is in no way unique to regenerative medicine, and the Agency may seek to narrow the intended uses that qualify as RATs in future guidance.

RAT Designation Process

Requests for RAT designation can be made concurrently or at any time after submission of an IND. FDA is required to respond within 60 days. If CBER’s Office of Tissues and Advanced Therapies (“OTAT”) determines that a RAT designation request is incomplete or that the drug development program does not meet the criteria for designation, it will inform the sponsor and include a written description of the rationale for its determination. FDA’s RAT website also provides that:

• Sponsors should refer to FDA’s Expedited Programs Guidance for FDA’s interpretation of whether a disease or condition is “serious or life-threatening” and whether a drug is “intended to treat a serious disease or condition.”
• Consistent with fast track and breakthrough therapy designations, FDA does not expect that sponsors submit primary data. Instead, FDA requests that sponsors describe the preliminary clinical evidence.
• Sponsors should provide a brief description of any available therapies for the disease or condition, the study design, the population studied, and the endpoint(s) used, and a description of the study results and statistical analyses (e.g., subgroup analyses).
• Requests for RAT designation should be submitted to OTAT.
• The cover letter for a request should clearly specify that the submission contains a “REQUEST FOR REGENERATIVE ADVANCED THERAPY DESIGNATION” in bold, upper case letters.

Benefits of RAT Designation

RAT designation affords the following benefits to sponsors:

• Expedited development and review by FDA (i.e., the same actions as for breakthrough therapy designation);
• Early interactions “to discuss any potential surrogate or intermediate endpoint to be used to support the accelerated approval of the product;” and
• Eligibility for accelerated approval under current FDA preapproval standards but with new postapproval requirements.

Signaling for Expanded Use of Accelerated Approval

The new postapproval requirements are a key differentiating factor from the breakthrough therapy designation. Sponsors of RAT-designated products approved via the accelerated approval pathway have additional options to meet post-approval requirements beyond the standard, controlled clinical trial. Post-approval requirements can be met through:

• Clinical evidence, clinical studies, patient registries, or other sources of real world evidence, such as electronic health records;
• The collection of larger confirmatory data sets; or

Postapproval monitoring of all patients treated with such therapy prior to approval of the therapy.

The new designation, therefore, encourages FDA to further develop and utilize the Subpart H/accelerated approval pathway. For a comprehensive review of FDA’s use of accelerated approval, refer to our paper, here.

Notably, the January 2015 House version of 21st Century Cures at section 2041 addressed regenerative medicine from a different angle. It directed FDA to issue a guidance document on surrogate and intermediate endpoints for accelerated approval of regenerative medicine products. Although this original approach was less ambitious, it also highlighted the need for accelerated approval to bring to market products in the budding field of regenerative medicine.

In late November, FDA announced that it would not be finalizing the 2014 draft LDT Guidance.  The Agency had, however, done a significant amount of work regarding the draft guidance and evaluating the regulatory framework for lab tests.  In an effort to document the work that it had done and further the public discussion regarding LDTs, FDA issued a discussion paper on Friday (the 13th) laying out key elements of a possible revised future LDT regulatory framework.

Released in the last week of the Obama administration, the discussion paper is in no way a formal proposal by FDA. We think, however, it is worth noting a few key elements that could potentially appear in a renewed attempt to regulate LDTs in a new administration.  The discussion paper states the following:

• LDTs on the market at the time a final guidance is issued would not be expected to comply with any FDA regulatory requirements except for MDR reporting, unless necessary to protect the public health;

• Certain categories of LDTs entering the market after issuance of a final guidance would be exempt from regulation, unless necessary to protect the public health.  These categories are consistent with the proposed LDT guidance and included, among others, low risk LDTs, LDTs for rare diseases, and Traditional LDTs;

• FDA has the ability to regulate any of the exempt LDTs if it concludes that the test is not analytically or clinically valid or there is insufficient data to support analytical or clinical validity, the LDT manufacturer has engaged in deceptive promotion, or there is a reasonable probability that an LDT will cause death or serious adverse health consequences (in other words, FDA believes it can regulate selected LDTs);

• For the remaining tests that will be subject to FDA regulatory oversight, the requirements would be phased in using a risk-based approach in four years rather than nine years as proposed in the draft guidance;

• Tests that enter the market after a final guidance is issued but before their phase-in date could be offered commercially during its premarket review, and manufacturers would have two years to comply with the Quality System Regulation (QSR);

• The third-party premarket review program could be expanded to accept certain LDT approvals, including, for example New York Department of Health (note: the discussion paper does not consider the statutory limitations to having a third-party reviewer evaluate clinical data related to an LDT);

• FDA could accept compliance with the Clinical Laboratory Improvement Amendments quality requirements to satisfy the QSR, with the exception of design controls, acceptance activities, and corrective and preventive actions (CAPA);

• Evidence of clinical validity should be made publicly available; and

• Changes to LDTs would require premarket review if the change significantly changes the performance specifications or intended use of the test.

As we discussed in our last LDT post (see here), there are a number of ways FDA could still attempt to regulate LDTs even without a final guidance.  The discussion paper does not allude to how FDA could proceed to indirectly regulate LDTs until it puts forth a new LDT proposal, beyond noting that FDA reserves the right to attack LDT tests it considers invalid.

The discussion paper does, however, make clear that FDA believes compliance wouldn’t be too burdensome for laboratories. Whether that assessment is correct is debatable.  For example, the discussion paper says that “clinical validity, especially of established tests, can often be supported by literature, well-curated databases, or other appropriate sources that meet the valid scientific evidence standard.”  As we have previously noted, FDA rarely accepts data other than prospective clinical studies; even performing studies using banked samples can be difficult.  It is possible that third-party reviewers may be more accepting of alternative forms of clinical data; however, we do not expect FDA would change its standards.

As is so often the case, the devil is in the details. Assuming FDA does resume its quest to regulate LDTs, we will have to wait quite a while to learn the details.

FDA’s October 6, 2016 Final Rule implementing certain provisions of the December 8, 2003 Medicare Modernization Act (“MMA”), Pub. L. No. 108-173, 117 Stat. 2066, ushered in a lot of changes for NDA and ANDA applicants and sponsors (see our previous post here).  The new regulations went into effect on Monday, December 5, 2016, and FDA immediately began to enforce them.

While we’re likely to see controversy and various issues crop up in the years to come as the new MMA rules are tested, one of the new requirements in particular has come up over and over again in the weeks since December 5, 2016. It concerns ANDA amendments and new 21 C.F.R. § 314.96(d).  (The corresponding regulation applicable to 505(b)(2) NDA applicants is at 21 C.F.R. § 314.60(f).)  This regulation states:

(d)(1) Patent certification requirements.  An amendment to an ANDA is required to contain an appropriate patent certification or statement described in Sec.  314.94(a)(12) or a recertification for a previously submitted paragraph IV certification if approval is sought for any of the following types of amendments:

(i) To add a new indication or other condition of use;

(ii) To add a new strength;

(iii) To make other than minor changes in product formulation; or

(iv) To change the physical form or crystalline structure of the active ingredient.

(2) If the amendment to the ANDA does not contain a patent certification or statement, the applicant must verify that the proposed change described in the amendment is not one of the types of amendments described in paragraph (d)(1) of this section.

New Subsection (d)(1) codifies FDA’s position, developed over the past decade or so, that certain changes proposed in an ANDA amendment require an applicant to recertify to patent information listed in the Orange Book for the brand-name RLD, and, in the case of a Paragraph IV certification, to provide a new notice of Paragraph IV certification. A patent infringement lawsuit filed in response to such a renotification can result in the imposition of a superseding 30-month litigation stay on ANDA approval.  We previously blogged on that issue here, and there are various FDA Citizen Petition Decisions discussing the issue (Docket No. FDA-2012-P-0943; Docket No. FDA-2011-P-0127; Docket No. FDA-2010-P-0223; Docket No. FDA-2010-P-0632), as well as instances in which the issue has been raised in patent infringement litigation because of a product change in an amendment (See, e.g., Alza Corp. et al. v. Impax Laboratories Inc. et al., Case No. 1:10-cv-01024 [here]; Alza Corp. et al. v. Impax Laboratories, Inc. et al., Case No. 1:11-cv-00395 [here]; Teva Branded Pharmaceutical Products R&D Inc. et al. v. Perrigo Pharmaceuticals Co. et al., Case No. 13-cv-01441 [here]).

New Subsection (d)(2) is a new requirement. FDA explains in the preamble to the MMA Final Rule that “if the amendment to the 505(b)(2) application or ANDA does not contain a patent certification or statement, the applicant must verify that the proposed change described in the amendment is not one of the types of amendments described in Sec. Sec. 314.60(f)(1)(i) through (iv) and 314.96(d)(1)(i) through (iv).”  And when FDA says “must,” the Agency really means “must.”

Immediately after the December 5, 2016 effective date of the new regulations, FDA’s Office of Generic Drugs (“OGD”) provided ANDA applicants with a courtesy reminder (often by phone) that any ANDA amendment, if it does not contain a patent certification (or section viii statement), must include a verification statement pursuant to 21 C.F.R. § 314.96(d)(2). The verification statement can be rather simple, and may be included in a cover letter to the ANDA amendment.  For example, “This amendment does not seek approval for a change listed in 21 C.F.R. § 314.96(d)(1),” or “I verify this amendment is not listed in 21 C.F.R. § 314.96(d)(1).”

In recent weeks, OGD appears to have stopped providing courtesy reminders by phone to ANDA applicants. Instead, OGD is sending out more official correspondence saying that an amendment submitted without a verification is deficient.  Here’s an example of such correspondence:

This is in reference to your abbreviated new drug application (ANDA) XXXXXX for [DRUG]. Your amendment dated [DATE], was submitted to the Agency on or after December 5, 2016, the effective date of the final rule on Abbreviated New Drug Applications and 505(b)(2) Applications; Final Rule, 81 FR 69580 (Oct. 6, 2016).  This rule revised 21 CFR 314.96(d), which concerns amendments to unapproved ANDAs.  In part, the rule now requires an amendment to an unapproved ANDA to contain an appropriate patent certification or section viii statement described in 21 CFR 314.94(a)(12), or a recertification for a previously submitted paragraph IV certification, if approval is sought for changes described in any of the following types of amendments:

(i) To add a new indication or other condition of use;

(ii) To add a new strength;

(iii) To make other than minor changes in product formulation; or

(iv) To change the physical form or crystalline structure of the active ingredient.

If an amendment to an unapproved ANDA does not contain a patent certification or section viii statement, or a recertification, the applicant must verify that the proposed change described in the amendment is not one of the types of amendments described above.

Your amendment is deficient under 21 CFR 314.96(d). It currently does not contain (1) a patent certification or section viii statement, (2) a recertification, or (3) a verification statement.  As appropriate, please submit a patent certification or section viii statement, a recertification, or a verification statement (referencing your amendment dated [DATE]).

For future reference, to comply with the requirement of 21 CFR 314.96(d), we recommend that a patent certification or section viii statement, or recertification be referenced in the cover letter of an amendment to an unapproved ANDA and included in module 1.3 of such unapproved ANDA. Similarly, we recommend that a verification statement be included in the cover letter of an amendment to an unapproved ANDA.  For inquiries related to this requirement please contact the Patent and Exclusivity Team at CDER-OGDPET@fda.hhs.gov.

Avoiding such a deficiency letter is relatively simple: Remember to incorporate the verification in any template correspondence for an ANDA amendment.

We’ll probably see more from FDA and other interested parties on the new verification requirement as new scenarios crop up. (And we’re likely to see a lot of ink spilled on what types of amendment changes might trigger the patent certification/recertification requirement.  After all, the phrase “other condition of use” at 21 C.F.R. § 314.96(d)(1)(i) seems pretty ambiguous.) In fact, we’ve already come across one instance that seems to run contrary to the “either/or” choice FDA explains in the preamble to the MMA Final Rule (i.e., “if the amendment to the 505(b)(2) application or ANDA does not contain a patent certification or statement, the applicant must verify. . . .”). In the case of a timely-listed later-listed Orange Book patent, an ANDA applicant must certify to the patent in an amendment; however, the amendment may not be for one of the changes listed at 21 C.F.R. § 314.96(d)(1), and thus requires a verification under 21 C.F.R. § 314.96(d)(2).

Hardly a day goes by that we don’t see a press release or announcement that a company has requested or received from FDA’s Office of Orphan Products Development (“OOPD”) designation of its drug or biological product as an “orphan drug.” There’s a reason for that: FDA is receiving orphan drug designation requests at a record rate of 1.6 per day (2.23 per work day in 2016), and is granting designation requests at a near-record rate of 0.9 per day (1.28 per work day in 2016)!  If you haven’t already guessed, it’s time for the FDA Law Blog’s annual rundown of orphan drug designations and approval!

In 2016, FDA’s orphan drug program continued to break new ground with massive numbers of orphan drug designation requests. Orphan drug designations and approvals (which include not only approvals of NDAs for new molecular entities and BLAs for original biological products, but also applications approved for new orphan uses of previously approved drugs and biologics) dipped slightly from 2015, but not by much (see our previous post here).  2016 was still the second best year for orphan drug designations, and the third best year for orphan drug approvals since the enactment of the Orphan Drug Act.

FDA’s OOPD received an astonishing 582 requests for orphan drug designation in 2016.  That 110 more than the record set in 2015.  OOPD also granted an amazing 333 orphan drug designations in 2016.  That’s 21 fewer designations than the 2015 record, but still not too shabby.  There were 9 fewer orphan drug approvals in 2016 compared to the near-record-tying 48 approvals in 2015. (FDA set a record in 2014 with 49 orphan drug approvals.)  Since 1983, FDA has approved almost 600 orphan drugs, has granted nearly 4,000 orphan drug designations, and has received nearly 5,800 orphan drug designation requests.

Below are three tables – one for each metric we track – showing the year-by-year numbers since 1983. The numbers are largely based on information from FDA’s Orphan Drug Designations and Approvals Database.

Over the years, we’ve pointed out the fact that while OOPD’s workload continues to increase, the Office’s staff and resources have not kept pace. Despite the massive increase in workload and added responsibilities over the years, OOPD’s staff has remained at about 25 employees for quite some time.  Moreover, funding for OOPD has remained relatively flat over the past few years.

The stress on limited OOPD resources was apparent in a FDA Voice blog post from July 2016. There, Dr. Gayatri Rao, OOPD Director, noted the increased workload and the effect on meeting internal Office review goals:

[T]he sustained increase in designation requests over the last three years, coupled with the increasing number of incentive programs and competing workload priorities, have forced us to reconsider our internal review target. Reviewing these applications in an efficient and timely manner continues to be a top priority, but to ensure we continue to conduct these reviews with the appropriate level of care and consideration, our current goal is to review on average 75% of designation requests within 120 days of receipt.

Perhaps the soon-to-be-released budget will include some much needed additional funding for OOPD . . . . but we’re not holding our breath.

On Wednesday, January 25, 2017, a new chapter will begin in the decades-old story of FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”).  According to a note posted on the Electronic Orange Book website last week (as well as in a separate notice published on FDA’s website earlier this week): “On January 25, 2017, The Orange Book data will be updated to reflect the recent publication of the draft guidance for industry ‘Referencing Approved Drug Products in ANDA Submissions.’” This blogger, and presumably Orange Book aficionados everywhere, are pretty excited about the updates that are coming to both the electronic and print versions of the Orange Book (and presumably to the Orange Book Express app as well).

The draft guidance document FDA mentions in the note above – Referencing Approved Drug Products in ANDA Submissions (Docket No. FDA-2017-D-0114) – was one of many guidance documents FDA released in the days before the January 20, 2017 Presidential Inauguration.  And it’s a very, very welcome addition to the growing list of guidance documents in the Hatch-Waxman space.  Why?  Because in the draft guidance FDA defines and explains, for what is really the first time (with the exception of some new definitions included in FDA’s recent rules implementing the 2003 Medicare Modernization Act), terms fundamental to Hatch-Waxman and ANDA submissions that have for many years been misunderstood or misused (by FDA and the pharmaceutical industry).

Those terms are “Reference Listed Drug” (“RLD”), “Reference Standard,” and “Basis of Submission.” Each term refers to something very specific and critical to an ANDA submission.  Way back in 2012, we attempted to highlight the differences among these terms in a post titled “Big RLD” Versus “Little rld” – What’s the Difference?  But now we have something official from FDA that provides both a full explanation of the terms, as well as FDA policies relevant to each term.  Here’s a summary of the RLD, Reference Standard, and Basis of Submission concepts FDA provides in an appendix to the draft guidance:

• The reference listed drug (RLD) for an ANDA is the drug product that the proposed generic drug is intended to duplicate and to which the ANDA applicant must refer in its ANDA. The RLD must be a listed drug approved under section 505(c) of the FD&C Act based on a demonstration of safety and effectiveness. FDA identifies in the Orange Book listed drugs that are eligible to be RLDs. Starting in 2017, FDA intends to modify the Orange Book to clarify which listed drugs are RLDs and which are reference standards, and to indicate which products in the Discontinued Section may be referred to as an RLD. In the electronic Orange Book, there will be a column for RLDs. In the printed version of the Orange Book, the RLDs will be identified by a specific symbol.
• In vivo bioequivalence studies needed to support an ANDA must be conducted using the drug product that FDA has selected as the reference standard. The reference standard may or may not be the same listed drug as the RLD. While the reference standard is selected by FDA for the purposes of conducting any in vivo bioequivalence testing required for approval, all other comparisons of the proposed generic drug to determine whether it meets the statutory requirements for approval under section 505(j) of the FD&C Act (e.g., sameness requirements) generally must be to the RLD. The reference standard for a drug product selected by FDA generally is identified in the Orange Book. In the electronic Orange Book, there will be a column for reference standards. In the printed version of the Orange Book, the reference standards will be identified by a specific symbol.
• If you mistakenly identify the reference standard as the RLD in your ANDA, you may submit an amendment to a pending ANDA or a supplement to an approved ANDA to correct the information. FDA considers this error to be a deficiency related to identification of the appropriate listed drug as the RLD, rather than a change in the RLD itself. The cover letter for such a submission should clearly identify that the purpose of the submission is “Correction of RLD information.”
• The basis of submission statement in an ANDA (e.g., in section 1.12.11 of the ANDA) and in Form FDA 356h (field 20) should include the RLD and the RLD application number. For a petitioned ANDA, the basis of submission statement in the ANDA (e.g., in section 1.12.11 of the ANDA) also should include a reference to the FDA-assigned docket number for the suitability petition and a copy of FDA’s correspondence approving the suitability petition. The reference standard, if it is different from the RLD, should be identified in the appropriate sections of the ANDA (e.g., sections 1.12.11, 2.7.1, 5.2, and 5.3.1).

As FDA notes above, modifications to the Orange Book are on the way. And those changes will go live on January 25, 2017. But we don’t have to wait until then to get a peek at the new Orange Book. FDA recently published a 17-minute webinar explaining the changes to the Orange Book and the policies laid out in the draft guidance. In a presentation accompanying the webinar, FDA shows how the electronic and print versions of the Orange Book will be modified. In the print version of the Orange Book, RLDs will continue to be identified by the “+” symbol; however, FDA will now identify Reference Standards by the “!” symbol. Here’s an example:  The Orange Book Express app, which FDA introduced to the world on November 9, 2015 (see our previous post here), will also presumably be updated to reflect the new RLD and Reference Standard changes.We assume that other changes will also be made to the Orange Book with the introduction of the 2017 (and 37th) edition . . . and to the Preface in particular. That being said, we don’t anticipate quite the facelift that the Preface got last year (see our previous post here). At the very least, we assume that the Preface will be updated to remove any mention of LIBRAX as a drug product covered by an ongoing Drug Efficacy Study Implementation proceeding. After all, FDA only recently discovered and affirmed that LIBRAX is an approved drug . . . and has been for decades, according to the Agency (see our previous post here).

In the electronic version of the Orange Book, RLDs are now identified by “RLD” in the RLD column (instead of a “Yes” or “No”), and Reference Standards will be identified by “RS” in a new RS column. Here’s an example.

The Hemp Industries Association has filed a Petition for Review in the Ninth Circuit to block implementation of the Drug Enforcement Administration’s (“DEA’s”) recent final rule on Marijuana extracts. The DEA final rule designates non-psychoactive cannabinoids, including cannabidiol, as “marihuana extract” and adds all cannabinoids, including exempted portions of the Cannabis sativa L. plant, to schedule I of the federal Controlled Substances Act (“CSA”).  See Establishment of a New Drug Code for Marihuana Extract, 81 Fed. Reg. 90,194. 90,196 (Dec. 14, 2016) (here).

The petition seeks judicial review of DEA’s final rule creating a new drug code without following required CSA procedures or making findings required by the CSA to control substances. The petition claims that DEA’s rule creates a drug code for substances that are not controlled under the CSA; that the final rule “dictates that the mere presence of ‘cannabinoids,’ which are not controlled substances, is the determinative factor of whether a compound is a ‘marihuana extract.’” Petition at 2. It further claims that the final rule too broadly defines “marihuana extract” by including portions of the Cannabis sativa L. plant that are exempt from control under the CSA or exempt from being treated as controlled substances pursuant to the CSA and the Agricultural Act of 2014. Id. at 2-3.

The CSA defines “marihuana” as “all parts of the plant Cannabis sativa L., whether growing or not; the seeds thereof; the resin extracted from any part of such plant; and every compound, manufacture, salt, derivative, mixture, or preparation of such plant, its seeds or resin” but excludes “the mature stalks of [the] plant, fiber produced from [the] stalks, oil or cake made from the seeds of [the] plant, any other compound, manufacture, salt, derivative, mixture, or preparation of [the] mature stalks (except the resin extracted therefrom), fiber, oil, or cake, or the sterilized seed[s] . . . incapable of germination.” 21 U.S.C. § 802(16). Yet, the DEA final rule on marijuana extracts appears to include all portions of the marijuana plant, including those specifically excluded by the CSA from the definition of marijuana.

Petitioner, the Hemp Industries Association, successfully challenged DEA’s 2003 rulemaking that amended the regulation to include naturally occurring tetrahydrocannabinols (“THC”) within the definition of “synthetic THC” and, therefore, treat it as a schedule I substance, even though it falls outside the CSA definition of marijuana. Hemp Indus. Ass’n v. DEA, 357 F.3d 1012 (9th Cir. 2004) (here). The Court of Appeals for the Ninth Circuit concluded that DEA “cannot regulate naturally-occurring THC not contained within or derived from marijuana – i.e., non-psychoactive hemp products – because non-psychoactive hemp is not included in Schedule I.” Id. at 1018. The Court held that DEA’s broadening of the definition of THC to include naturally occurring THC “contravenes the unambiguously expressed intent of Congress in the CSA and cannot be upheld.” Id. The Court permanently enjoined DEA from enforcing the rules scheduling THC. Id. at 1019. However, the Court’s decision is limited to the Ninth Circuit.

It will be interesting to follow this petition given how the marijuana/hemp/THC state regulatory landscape has changed considerably since 2004.
