MEMORANDUM OPINION

ROGER W. TITUS, District Judge.

Benlysta® is a drug developed and marketed by Defendants Human Genome Sciences, Inc. (“HGS”) and Glaxo Smith Kline, PLC (“GSK”) for the treatment of lupus. It was approved by the FDA in 2011, and was the first new treatment for lupus approved in 56 years. During several clinical trials involving more than 1,900 patients, Defendants learned that three participants had committed suicide. Defendants allegedly concealed these facts from investors, who consequently suffered significant stock losses when the information later became public. These investors, the Plaintiffs in the present case, have brought this class action charging violations of the anti-fraud provisions of the federal securities laws.

Claims of security fraud carry a heightened pleading standard. A plaintiff must establish not only that the defendant acted wrongfully, but that it acted with scienter (ie., wrongful intent or purpose) as opposed to mere negligence. As Plaintiffs have failed to allege facts that give rise to a strong inference that Defendant purposefully concealed the adverse effects of Benlysta, Defendants’ Motions to Dismiss [ECF Nos. 29 and 30] must be granted.

Background1

HGS is a biopharmaceutical company that developed a breakthrough lupus drug called Benlysta. See Am. Compl. ¶ 25, ECF No. 25. Beginning in October 2003, HGS started its Phase 2 “blinded” drug study, known as L02. Id. ¶ 28; see HGS Mot. Dismiss Ex. E, Journal of the American College of Rheumatology, ECF No. 29-7. During this clinical trial, one patient committed suicide.2 See Am. Compl. ¶ 72.

The L02 study ended in February 2006 and HGS began a second study, LBSL99, which followed former L02 patient participants for a number of years. Id. ¶28. Unlike the Phase 2 L02 blind study, the LBSL99 extension study was “unblinded” and had no control group. Id. During the course of the LBSL99 study, one patient committed suicide and two more attempted suicide. Id.

Before HGS began its Phase 3 studies of Benlysta, it entered into a co-development [754]*754and co-commercialization agreement with GSK. Id. ¶29. Under the terms of the agreement, GSK would assist with the Phase 3 trials. Id. The Phase 3 trials consisted of the BLISS-76 study and the BLISS-52 study. Id. ¶ 33. One suicide occurred in the BLISS-52 study; no suicides occurred in the BLISS-76 study. Id. ¶ 72.

Throughout the course of Benlysta’s development and prior to Benlysta’s ultimate approval by the FDA, HGS and GSK issued various press releases touting Benlysta’s safety and efficacy. Id. ¶¶ 35-65. HGS’s officers also conducted analyst calls and made investor presentations in which they discussed the Phase 2 L02 trial, the Phase 3 BLISS-52 and BLISS-76 trials, and Benlysta’s safety profile. Id. On several occasions, HGS discussed the correlation between suicide and Benlysta, but only with respect to the suicides in the Phase 2 L02 and the Phase 3 BLISS-52 studies. Id. The attempted and actual suicides in the LBSL99 extension study were not mentioned. Id.

In November of 2006, HGS issued a press release informing the investing public that the results of the Phase 2 blinded L02 trial would be discussed at the American College of Rheumatology’s annual conference. See HGS Mot. Dismiss Ex. C, November 14, 2006 Press Release, ECF No. 29-5 at 1. At the conference, HGS’s officers revealed that an individual committed suicide during the Phase 2 blinded L02 trial, but that the investigator had determined that the suicide was “not related” to Benlysta. See HGS Mot. Dismiss Ex. D, Power Point, ECF No. 29-6 at 11.

In September of 2009, physicians and an HGS executive published the results of the Phase 2 blinded L02 trial in the Journal of the American College of Rheumatology, discussing the single suicide associated with that particular study. See HGS Mot. Dismiss Ex. E, Journal of the American College of Rheumatology, ECF No. 29-7 at 8.

In November of 2009, HGS held a conference call for all investors. See HGS Mot. Dismiss Ex. G, November 2, 2009 Press Release, ECF No. 29-9; Amend. Compl. ¶ 48. During the conference call, a Citigroup analyst discussed the suicide in the Phase 2 blinded L02 trial and raised questions about the suicide in the Phase 3 blinded BLISS-52 trial. See HGS Mot. Dismiss Ex. F, November 2, 2009 Transcript Analyst Call, ECF No. 29-8 at 8. After the call, Citigroup published an analyst note in which it discussed the two suicides. See HGS Mot. Dismiss Ex. H, November 2, 2009 Citigroup Analyst Report, ECF No. 29-10 at 8.

HGS executives did make vague, passing references to the ongoing unblinded LBSL99 study on three occasions. First, on September 9, 2009, HGS Chief Commercial Officer Labinger made the following statement at the Thomas Weisel Partners Healthcare Conference:

So first turning to BENLYSTA, again potentially the first new lupus drug in 50 years. This is the primary endpoint that we saw in BLISS-52, the first of our two Phase 3 global trials. The safety was very impressive. No difference in overall adverse events or serious adverse events or infections, which were a category of interest for us. No difference in fatalities across those groups for BENLYSTA and placebo. You see a list of the common adverse events, but there are no differences between groups and those either. There were no malignancies reported in the trial overall. So we’re very pleased so far with the safety profile. We’ve got patients from our Phase-II program on drugs through four to five years now and see a similar experience and we are obviously diligently track [sic] safety going into the [755]*755future as we get larger numbers on treatments for longer periods of time.

See Am. Compl. ¶ 48.

Second, on June 15, 2010, HGS CEO Watkins made the following presentation to investors at the Goldman Sachs Global Healthcare Conference:

There was no data we saw in there which did not confirm for us a continued strong therapeutic benefit. I think of equal importance here is the issue of safety. We now have, from the Phase 2 study, and we’ve continued many of those patients, some patients from our Phase 2 study, which was unblinded in '05, have continued on study drug. Now, some have been on study drug now for as much as five, six years, I think we have a few on six years.... We will continue — we show that data every six months at EULAR or ACR. So, maybe this week, you will see that data.
What we see from those patients, as well as from the patients in both of the Phase 3 studies is a very positive safety profile. And as you know, one of the areas of concern to physicians, when they prescribe long-term immunomodulatory agents, is what is the impact on the patient’s overall well-being over a considerable period of time. Now we will continue, we must continue to be very diligent in tracking safety on a continual basis, we understand that. But certainly what we will present — what we have presented to the FDA and the EUA we believe is a very positive profile relative to both efficacy and safety.
