The opinion of the court was delivered by: James Robertson United States District Judge
Merck & Co. holds the U.S. patent on the highly successful anti-cholesterol drug lovastatin, which Merck markets as Mevacor®. The patent was to expire on June 15, 2001. On that date, at least two manufacturers of generic equivalents *fn1 were waiting for approval of their applications to market generic versions of Mevacor. On the same date, Merck was waiting for FDA approval of its application for a six-month extension of its patent rights, pursuant to the Food and Drug Administration Modernization Act of 1997 (FDAMA), codified in part at 21 U.S.C. § 355a, after its earlier submission of a FDA-requested study of the effect of lovastatin on children. At 4:18 p.m. EST on June 15, 2001, FDA's Division of Metabolic and Endocrine Drug Products faxed to Merck a memorandum from the Pediatric Exclusivity Board denying Merck's application for pediatric exclusivity. That same day *fn2 FDA approved five abbreviated new drug applications (ANDAs) for generic equivalents of Mevacor. Merck immediately brought this action, asserting that FDA's denial of "pediatric exclusivity" was arbitrary, capricious, or otherwise not in accordance with law, in violation of the Administrative Procedure Act.
I granted Merck's application for a temporary restraining order on June 16, 2001 - staying the effectiveness both of FDA's refusal to grant six-month exclusivity under FDAMA and of the ANDA approvals - and set Merck's application for preliminary injunction down for hearing at 4 p.m. on June 19, 2001. After that hearing, and for the reasons set forth in this memorandum, I have decided to extend the temporary restraining order for an additional ten days pursuant to Fed. R. Civ. P. 65(b), to order the trial of the merits of this action to be advanced and consolidated with the hearing of Merck's application for a preliminary injunction pursuant to Fed. R. Civ. P. 65(a), and to set the matter down for trial on July 3, 2001, at 9:30 a.m.
FDAMA, enacted in 1997, provides a six month extension of the statutory market exclusivity given to a new drug if, upon FDA's request, the manufacturer studies the effect of the drug on children. In order to qualify for this "pediatric exclusivity" period, drug manufacturers must comply with either 21 U.S.C. § 355a(d)(2) or (d)(3), which are the applicable statutory standards.
On May 20, 1998, FDA included lovastatin as a priority drug on the Pediatric List. Merck submitted a proposed written request for pediatric studies to FDA on August 13, 1998. After staff discussions, on February 3, 1999, FDA issued a formal written request pursuant to 21 U.S.C. § 355a(d)(1) for information on a study of lovastatin in adolescent males (which Merck had already completed) and on a study supplementing the existing data on adolescent males with information on the use of lovastatin in adolescent girls aged 10-17. The written request contained no specification of how many girls should be treated, what the duration of treatment should be, or what the duration of the study should be. Merck responded with a proposed "written agreement" that would have provided further details of the proposed study, *fn3 but FDA declined to enter into a written agreement.
On May 18, 1999, the FDA amended its written request to specify a desired trial period of six months instead of the three month period detailed in Merck's written proposal. As amended, the written request asked for a "placebo-controlled trial in adolescent girls of a minimum six months' duration." Merck then formally submitted to FDA the protocol for its proposed study, showing, among other things, that the study duration would be 28 weeks, including a four week placebo "run in" period, and that the duration of treatment on lovastatin would be 24 weeks, with a seven day period of leeway (earlier or later) to accommodate the scheduling needs of study participants. FDA did not inform Merck that this study design would be inadequate to meet the six month duration requirement of the amended written request.
Merck submitted its pediatric study reports to FDA on April 18, 2001. FDA had ninety days, or until July 17, 2001, in which to evaluate these reports, 21 U.S.C. § 355a(e), but it acted in less than sixty days. The June 15, 2001 memorandum of the Pediatric Exclusivity Board (which for purposes of this proceeding will be assumed to have been final agency action) stated the following reason for its conclusion:
[O]nly 5 girls were treated with lovastatin for 6 months or more. A study in which only 5 girls were treated for 6 months or more could well miss potential safety issued associated with long-term exposure, if any. Therefore, the Board concluded that Merck failed to meet this term of the WR and pediatric exclusivity is denied. (Emphasis added.
What Merck challenges is a decision of FDA's "Pediatric Exclusivity Board." I have subject-matter jurisdiction because the determination was final and because there is no means of obtaining further review by the FDA; no party has suggested otherwise. The Board's action is an informal adjudication, reviewable under the "arbitrary, capricious, or otherwise not in accordance with law" rubric of the Administrative Procedure Act.
At this stage of the record's development, it appears that the Board's determination is "not in accordance with law" because it invokes a standard not specified in the statute. A denial of pediatric exclusivity for failure to meet a single term of a written request would not be in accordance with section 355a(d)(3), which plainly does not require compliance with every single provision of a written request, but requires only that a pediatric study "fairly respond" to a written request. *fn4 Nor would it be consistent with the statutory standard to deny pediatric exclusivity because of disappointment with data submitted by a manufacturer if the study as a whole is a fair response to the written request.
I have said "it appears" that the Board employed the wrong standard because the Board's memorandum fails to provide an adequate statement of the rationale for its decision. It is not clear from the memorandum whether the Board even considered the study as a whole in evaluating whether Merck had "fairly respond[ed]" to the written request. The Board provided no reasoned explanation of why it ultimately concluded that the length of Merck's study or the number of participants made the study not "fairly respon[sive]," nor did it give any indication that it employed the sort of "care,  consistency, [and] formality" in making its decision that is necessary before this Court - or any court - owes it substantial deference.
