In July 2004, the Coalition for Mercury-Free Drugs (the Coalition) filed a citizen petition with FDA requesting that the agency prohibit the use of thimerosal and other mercury compounds in vaccines and drugs.  In August 2006, the Coalition went to court claiming that FDA had unreasonably delayed responding to the Coalition’s petition.  Shortly thereafter, in September 2006, FDA denied the petition, thereby effectively mooting the Coalition’s claim.  To prevent dismissal of the case, the Coalition amended its complaint to challenge the substance of FDA’s decision.  However, one day earlier, the Coalition had filed a petition with FDA requesting a stay of action, asking FDA to reconsider and modify its response to the original petition.  The Coalition’s petition for a stay of action contained new information and documents that FDA had not reviewed.  Although the Coalition styled the petition as a petition for a stay of action, in reality it was a petition seeking reconsideration of FDA’s response to the original petition.

By filing a petition for a stay in which the Coalition presented new information, the Coalition essentially transformed FDA’s decision into a non-final agency decision, thereby resulting in the dismissal of the court case.  By filing the petition for a stay, the Coalition effectively sought FDA reconsideration, as well as judicial relief of the substantive decision.  As the United States District Court for the District of Columbia noted in its March 1, 2007 memorandum opinion, “plaintiffs cannot simultaneously seek administrative consideration and judicial review of the same order.”  In essence, the Coalition was asking the court to review FDA’s decision regarding certain materials that the agency did not have an opportunity to review.

In Late February 2007, FDA announced in the Federal Register the withdrawal of approval of 128 suitability petitions in accordance with the Pediatric Research Equity Act of 2003 (“PREA”).  FDA’s notice states:

[T]hese approval decisions are being withdrawn because ANDAs were never submitted and PREA requires that all applications submitted on or after April 1, 1999, for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration contain an assessment of the safety and effectiveness of the drug for the claimed indications in relevant pediatric subpopulations unless the requirement is waived or deferred.

Under PREA and new FDC Act § 505B, Congress granted FDA the authority to require pediatric studies in certain defined circumstances.  Specifically, FDC Act § 505B states that an applicant “that submits an application (or supplement to an application) under section 505 [of the FDC Act] for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration . . . shall submit with the application” the results of pediatric studies assessing “the safety and effectiveness of the drug . . . for the claimed indications in all relevant pediatric subpopulations; and to support dosing and administration for each pediatric subpopulation for which the drug . . . is safe and effective, [unless FDA] concludes that pediatric effectiveness can be extrapolated from adequate and well-controlled studies in adults, usually supplemented with other information obtained in pediatric patients,” or unless FDA defers or partially or fully waives this requirement. 

An ANDA requiring an approved suitability petition for a change to the Reference Listed Drug (“RLD”) in an active ingredient, route of administration, or dosage form meets the PREA criteria triggering a pediatric assessment.  (The only RLD change permitted by a suitability petition that does not trigger PREA is a change in strength.)  However, because of the statutory exception mandating FDA’s denial of a suitability petition requiring clinical studies, FDA can no longer approve suitability petitions for PREA changes unless the Agency fully waives the pediatric assessment requirement.

Because PREA is retroactive to applications submitted on or after April 1, 1999, any suitability petition for a PREA change granted prior to that date can no longer be relied upon today to provide a basis for FDA to approve an ANDA.  To grant such a petition, FDA would have to reassess the change pursuant to a new suitability petition in light of PREA.  FDA’s Federal Register notice concerns only suitability petitions for which ANDAs were never submitted, and is non-controversial.  However, FDA could arguably go one step further in its PREA clean-up efforts and identify post-April 1, 1999 ANDA submissions and approvals that relied on an approved suitability petition no longer valid in light of PREA.  Such a move, while it would be highly controversial and invite intense criticism of FDA, might not be out of the question. 

On February 27, FDA announced a draft guidance, titled Guidance for Industry on Complementary and Alternative Medicine Products and Their Regulation by the Food and Drug Administration (CAM Guidance).  The CAM Guidance was prepared by the Office of Policy and Planning within FDA’s Office of the Commissioner with assistance from the Center for Biologics Evaluation and Research, the Center for Drug Evaluation and Research, the Center for Devices and Radiological Health, and the Center for Food Safety and Applied Nutrition.  The CAM Guidance is FDA’s attempt to clarify within which FDA regulatory schemes (i.e., food, drug, device, biologic, cosmetic, or dietary supplement) the wide range of complementary and alternative medicine products might fall.  The areas addressed in the CAM Guidance include biologically-based practices, energy therapies, manipulative and body-based methods, and mind-body medicine.

The trade press has noted FDA’s statements that probiotics could be regulated as dietary supplements, foods, or drugs.  In its CAM Guidance, FDA also suggests that “the bacteria used in a probiotic could make the product a ‘biological product’ subject to the [Public Health Service Act].”  This statement appears to relate to the potential for probiotics to contain bacteria that might cause communicable disease.  However, the guidance should be clarified on this point to make sure it is consistent with other statements in the CAM Guidance that recognize the longstanding principle of intended use as the determining factor in the regulatory status of a product.

Companies developing complementary and alternative medicine products should read carefully the CAM Guidance, as it is not directed solely at probiotics and other foods.  For example, the CAM Guidance suggests that FDA may regulate equipment used and products applied in manipulative and body based-practices, such as massage devices, lotions, creams, and oils.

Comments regarding the CAM Guidance must be submitted to FDA by April 30, 2007.

On March 1, 2007, FDA announced that it issued 20 Warning Letters to companies marketing and distributing unapproved drug products containing ergotamine tartrate, a drug used to treat vascular headaches, including migraines. According to FDA’s press release announcing the enforcement action:

In addition to marketing these products without FDA approval, most of the companies receiving warning letters have omitted from their drugs’ labeling critical warnings regarding the potential for serious, possibly fatal, interactions with certain other drugs. Based on recent scientific information, the five marketed, approved versions of ergotamine-containing products have updated their labeling to include a box warning (the strongest agency warning) against using such products when also taking potent CYP 3A4 inhibitors, including some antifungal agents, protease inhibitors, and certain antibiotics.  CYP 3A4 is a metabolic enzyme that helps the body eliminate drugs or other chemicals.  Serious and life-threatening ischemia (a restriction in blood supply), including death and gangrene, have resulted when such products are used together.  Most unapproved versions of the drug do not carry these warnings.

FDA’s enforcement action is another example on a growing list of such actions taken to implement the risk-based enforcement approach described in the Agency’s June 2006 Compliance Policy Guide.  Moreover, it is the opening salvo this year for FDA to make good on its promise “to further accelerate its enforcement efforts against marketed unapproved drugs in 2007.”  As we recently reported in RAPS FOCUS, FDA’s stepped-up enforcement effort might be due to pressure from Congress and the threat of legislation addressing marketed unapproved drugs.
