In Re Sepracor, Inc. Securities Litigation, 308 F. Supp. 2d 20, 2004 U.S. Dist. LEXIS 4786, 2004 WL 585849 (D. Mass. 2004).

Opinion

MEMORANDUM AND ORDER

LASKER, District Judge.

This case is a consolidation of a number of securities fraud actions brought on behalf of all persons and entities who purchased common stock of Sepracor, Inc. (“Sepracor”) from April 14, 2000 through March 6, 2002 (the proposed “Class Period”). The various actions have been reduced to two Consolidated and Amended Complaints (the “Complaints”), one on behalf of equity securities purchasers and the other on behalf of debt purchasers, containing -virtually identical allegations. 1 The plaintiffs sue Sepracor and three of its officers, 2 alleging violation of Sections 10(b) and 20(a) of the Securities and Exchange Act of 1934, 15 U.S.C. §§ 78j(b) and 78t(a), and the corresponding Securities and Exchange Commission (“SEC”) Rule 10b-5, 17 C.F.R. § 240.10b-5.

Defendants move to dismiss all counts. The motion is GRANTED IN PART and DENIED IN PART.

I. Background

For the purposes of the present motion, the allegátions contained in the Complaints are accepted as true.

Sepracor is a pharmaceutical company primarily engaged in developing' derivatives of existing drugs. (Comply 31.) During the Class Period, Soltara, a non-sedating anti-histamine for the treatment of seasonal allergies, was the most promising drug in Sepracor’s pipeline, and the only drug for which Sepracor had filed a New Drug Application (“NDA”) with the Food and Drug Administration (“FDA”). (Id. ¶ 35.) By the end of 2001, Sepracor was losing money at á rate of $400 million per year, with enough funds on hand for approximately one more year. (Id. ¶ 34.)

Soltara is a modified version of Hisma-nal, which was an earlier generation of non-sedating antihistamine approved by the FDA in 1988 and used by millions of people over the following decade. (Id. ¶ 37.) In 1998, the FDA discovered that a very small number of people taking His-manal had died due to cardiac arrhythmia caused by “Qt prolongation” (instability of the heart’s electrical system, which can cause cardiac arrest). (Id.) On the basis of this finding, Hismanal was withdrawn from the market in 1999.' (Id.) Another earlier-generation non-sedating antihistamine, Seldane, had been withdrawn in 1997 for the same reason. (Id. ¶ 39.) In 2000 and 2001, the FDA stated publicly several times that no new antihistamine would be *25 approved if there was any risk of potential cardiac effects. (Id. ¶¶ 42-46.)

Drugs sold in the United States must first be approved by the FDA. Approval by the FDA requires preelinieal trials, usually done on animals, followed by at least three phases of clinical trials on humans (these trials are referred to as phases I, II, and III). When Phase III clinical trials are completed, the drug company files an NDA. After making its decision, the FDA sends one of three letters: an “approval” letter, a “not approvable” letter, or an “approvable” letter.

According to the Complaints:

.... [B]y 1999 Sepracor tested the effects of Soltara in dogs and rats. While the animal studies in each of the three FDA-approved second generation non-sedating antihistamines, Claritin, Allegra and Zyrtec[,] had not revealed any cardiac or other safety problems, in the dog and rat studies of Soltara, the drug caused potentially fatal cardiac effects, as well as liver damage. In dog studies, Soltara caused both Qt prolongation and phospholipidosis, a fat storage disorder which can result in drug-induced cirrhosis of the liver. In a rat study, Soltara caused cardiomyopathy, a potentially fatal disease of the heart muscle that causes the heart to lose its ability to pump blood, leading to cardiac arrhythmia. Moreover, the incidence of car-diomyopathy in rats treated with Soltara was dose dependent, i.e. the incidence increased with increasing doses of the drug, demonstrating that the cardiomyo-pathy was drug-induced. The rat study was disastrous for [Sepracor], because cardiomyopathy is highly unpredictable in humans, making it extremely difficult to prove that the drug would not cause cardiomyopathy in some humans. Due to the FDA’s announced zero tolerance policy for cardiac effects in antihistamines for which FDA approval was sought, the rat study as well as the Qt prolongation in a dog study meant that Sepracor would have to prove that Sol-tara could not cause potentially fatal cardiac effects in humans, which requires far more than the human safety studies that were conducted for the existing FDA-approved antihistamines or the safety studies conducted by Sepra-cor.

(Comply 53.)

Johnson & Johnson, which had agreed to jointly fund the development of Soltara and share the profits, withdrew its participation in May 1999, following the animal studies. (Id. ¶¶ 48-49.) Sepracor, however, continued to develop Soltara, proceeding to clinical trials. The aim of the clinical trials was to demonstrate that Soltara was safe to use in humans. According to the complaints, however:

Sepracor’s safety studies of Soltara, ... were not designed to provide the necessary evidence that the effects seen in animals could not occur in humans, because, inter alia, they did not provide evidence that the drug could not cause cardiac effects or organ damage at the highest possible accumulation in the patient’s body.

(Comply 54.) This was so, plaintiffs contend, because the clinical trials measured the safety of the drug only at maximum plasma (blood) concentration rather than at maximum tissue concentration. Antihistamines such as Soltara reach maximum plasma concentration within two weeks, but continue to build up in tissue for approximately ninety days.

As detailed below, plaintiffs allege that defendants made numerous public statements regarding the safety of Soltara that omitted any mention of the side effects that were observed in the animal studies. Defendants also made numerous state *26 ments expressing confidence that Soltara would gain FDA approval. Additionally, in public statements regarding the clinical trials, defendants-made reference to testing Soltara at “maximum concentration” without making clear that the level of concentration tested was maximum plasma accumulation rather than maximum tissue accumulation. Plaintiffs allege that these statements were materially misleading and artificially inflated the market price of Sepracor securities.

On March 7, 2002, Sepracor announced that- the FDA had issued a “not approva-ble” letter regarding the company’s application- to market Soltara. Sepracor issued a press release that day stating:

The FDA identified three issues that are not adequately addressed in light of certain aspects of the drug’s pharmacoki-netics and potential for accumulation in tissue.
