Opinion

Proceedings: (In Chambers) Order GRANTING in part and DENYING in part Defendant’s Motion to Dismiss the Consolidated Amended Complaint

PHILIP S. GUTIERREZ, District Judge.

In this class action for securities fraud, Plaintiffs allege that Defendants engaged in a scheme to deceive the investing public about the true value of Amgen stock. Defendants move to dismiss Plaintiffs’ Consolidated Amended Complaint for failure to state a claim. A hearing on the motion was held on January 28, 2008. Having considered the papers filed by the parties and oral argument on the motion, the Court GRANTS in part and DENIES in part Defendants’ motion to dismiss.

I. FACTS

A. Parties

Plaintiffs, including Lead Plaintiff Connecticut Retirement Plans and Trust Funds (collectively “Plaintiffs”), are members of a class of shareholders who purchased stock in Defendant Amgen, Inc. (“Amgen”) at an allegedly inflated price between April 22, 2004 and May 10, 2007 (“Class Period”). Defendant Amgen is a publicly traded company and the largest biotechnology company in the world. (CAC, ¶ 48.) During the time period relevant to this case, the individual defendants Kevin Sharer, Richard Nanula, Dennis Fenton, Roger Perlmutter, Brian McNa-mee, George Morrow, Edward Fritzky, Gilbert Omenn, and Franklin Johnson, Jr. (collectively “Individual Defendants”) were all officers and directors of Amgen.

*1018 B. Background

This action arises out of Amgen’s commercialization of two drugs — epoetin alfa, which Amgen markets in the U.S. as Epo-gen, and darbepoetin alfa, which Amgen markets in the U.S. as Aranesp. Both of these drugs are referred to as erythro-poietin-stimulating agents, or ESAs, because they stimulate the formation of red blood cells.

1. FDA Approvals

In 1989, the Food and Drug Administration (“FDA”) approved Epogen for the treatment of anemia associated with chronic renal failure, including end stage renal disease patients and patients with dialysis. (CAC, ¶ 37.) Later, the FDA approved the drug for persons who develop anemia as a consequence of chemotherapy for cancer, treatment of HIV infections with the pharmaceutical zidovudine, chronic kidney disease in pre-dialysis patients and anemic patients scheduled to undergo elective, non-cardiac, non-vascular surgery. (CAC, ¶ 38.) In 2001, the FDA approved Ara-nesp for the treatment of anemia associated with chronic renal failure, including patients on dialysis and those not on dialysis. (CAC, ¶ 42.) In 2002, Amgen secured FDA approval to market Aranesp for the treatment of anemia associated with cancer chemotherapy. (Id.)

2. Clinical Trials

In the late 1990’s and early 2000’s, there were several larger-seale clinical tests performed on ESAs, including the Normal Hemocrit Study, ENHANCE and BEST. (CAC, ¶ 33.) The Normal Hemocrit Study was a controlled study on patients with established heart disease. (CAC, ¶ 54.) The data safety monitoring board stopped the study because of a higher rate of blood clotting in patients randomized to the normal-level group. (Id.) Patients in that group also had a higher, but not statistically significant higher, rate of nonfatal heart attack and death. (Id.) The ENHANCE and BEST trials studied ESAs marketed in Europe but not approved by the FDA for use in the U.S. (CAC, ¶ 56.) The ENHANCE trial, which assessed the effect of an epoetin beta product — Neorecormon— on patients with head and neck cancer, resulted in “substantially shorter progression-free survival and overall survival than the placebo group.” (CAC, ¶ 55.) The BEST trial, administered to breast cancer patients, was stopped after four months due to increased mortality in patients receiving an epoetin alfa product called Eprex. (Id.)

3.The 200k ODAC Meeting

In light of the safety signals raised by the ENHANCE and BEST trials, the FDA convened a meeting in May of 2004 with the Oncology Drug Advisory Committee (“ODAC”), a group of leading experts in the field of oncology, to look into the safety of Aranesp and other ESAs. (CAC, ¶ 58.) In the weeks leading to the ODAC meeting, on April 22, 2004, Amgen, via Defendants Sharer, Nanula and Morrow, 1 held a conference call with analysts to discuss its earnings for the first quarter of 2004. (CAC, ¶ 59). When asked about the upcoming FDA meeting, Morrow allegedly “downplayed the significance of the meeting and the safety concerns of the FDA.” (Id.) Morrow told analysts that Amgen “had decided to participate in that meeting ‘cause the focus was not on Aranesp ... [and] there is no signal associated with Aranesp. We’ve had two perspective ran *1019 domized placebo controlled trials. And the safety for Aranesp has been comparable to placebo.” (Id.)

During the meeting, the FDA communicated to Amgen that in order to resolve the ESA safety issue, Amgen should conduct clinical trials meeting a number of pre-specified criteria. (CAC, ¶ 61). Am-gen also made a presentation outlining the “Amgen Pharmacovigilance Program,” five planned or ongoing clinical trials involving Aranesp in different tumor treatment settings. One of these trials, sponsored by the Danish Head and Neck Cancer Group (“DAHANCA”), tested high doses of Ara-nesp in subjects with head and neck cancer. (CAC, ¶¶ 62, 67.) David Parkinson, M.D., Amgen’s Vice President, Oncology Clinical Development, described the Am-gen Pharmacovigilance Program as a “responsible and credible approach to definitively resolving the questions raised[d] in this morning’s meeting.” (CAC, ¶ 63.)

A The DAHANCA 10 Trial

The DAHANCA 10 Trial tested whether high doses of Aranesp could aid in shrinking tumors of in patients with head and neck cancer receiving radiation therapy. (CAC, ¶ 64.) On October 18, 2006, DA-HANCA investigators temporarily halted the study “due to information about potential unexpected negative effects related to immunohistochemical estimation of the so-called EPO receptor.” (Id.) Pursuant to the DAHANCA 10 protocol, Amgen was informed of this development on or near October 18, 2006. (Id.)

On December 1, 2006, DAHANCA investigators terminated the study entirely. (CAC, ¶ 65.) According to the DAHANCA Interim Analysis, “there is a small but significant poor outcome in the patients treated with Aranesp” in that the tumor growth was worse for patients who took Aranesp than for those who did not. (Id.)

On February 16, 2007, The Cancer Letter, under the banner “Amgen Didn’t Tell Wall Street About Results of Danish Study,” reported that the DAHANCA trial had been halted in October 2006 because it showed “significantly inferior therapeutic outcome from adding Aranesp to radiation treatment of patients with head and neck cancer.” (CAC, ¶ 66.) That same day, Amgen’s stock dropped 2.3% to $66.73 per share. (CAC, ¶ 68.) On February 28, 2007, Amgen announced that it had received an inquiry from the SEC’s Atlanta District Office regarding the DAHANCA 10 Trial. (Id.) The following day, on March 1, 2007, Amgen stock fell from $64.26 per share to $61.70 per share. (Id.)
