Opinion

MEMORANDUM

YOHN, District Judge.

This is a consolidated class action in which plaintiffs are shareholders or former shareholders of Hemispherx Biopharma, Inc. (“Hemispherx”). Plaintiffs claim securities fraud under § 10(b) of the Securities Exchange Act of 1934 (“Exchange Act”) and Rule 10b-5 thereunder against Hemispherx; its President and Chairman of the Board Dr. William A. Carter; its Medical Director and Chief Medical Officer David Strayer; and its Senior Advisor Wayne Pambianchi. They further claim Hemispherx and Carter violated § 20(a) of the Exchange Act. The plaintiffs purport to represent all persons other than defendants who purchased or acquired Hemis-pherx common stock on the open market between March 14, 2012 and December 20, 2012, inclusive.

The subject of this litigation is the regulatory approval process of Ampligen, Hem-ispherx’s flagship drug which the Food and Drug Administration (“FDA”) had not yet approved for market as of the class period. The consolidated amended complaint (“complaint”) alleges that, during the class period, Hemispherx and its senior officials made numerous public statements that concealed and/or misrepresented information indicating Hemispherx was not likely to succeed in obtaining Ampligen approval.

Before the court is the defendants’ motion to dismiss, which contends plaintiffs have failed to state a claim under § 10(b) [338]*338and Rule 10b-5. The defendants further contend that, to the extent the plaintiffs have failed to state a claim under § 10(b), they have also failed to state a claim under § 20(a).

Drawing all inferences in the plaintiffs’ favor, one may reasonably infer from the complaint that the defendants made statements that were misleading and/or omitted information necessary to avoid their being misleading, as well as strongly infer the defendants knew this or were reckless if they did not know this. ’ The inference of scienter emerges from numerous, detailed allegations of specific information known to the defendants but not disclosed. The allegations are thus sufficient to state a claim, and the defendants’ motion will be denied.

I. Background1

A. The FDA New Drug Approval Process

Under 21 U.S.C. § 355, companies may market a pharmaceutical product in the United States only after submitting a new drug application (“NDA”) to the FDA and receiving the FDA’s approval. See 21 U.S.C. § 355. The FDA may approve a drug for market only where there is (a) sufficient information to determine the drug is safe to use as proposed, and (b) substantial evidence the drug will have the effect it is purported to have when used as proposed. § 355(d)(4)(5).

Where a company seeks to sponsor a previously untested drug for FDA approval, the company is responsible for undertaking clinical investigation to demonstrate the drug’s safety and effectiveness. See 21 C.F.R. § 312.21. This includes the design, conduct, and analysis of clinical trials. See id. WTien a sponsor believes that clinical investigation has produced the substantial evidence of safety and efficacy required by § 355(d)(4)-(5), it may then file an NDA with the FDA based on that evidence. Even then, the FDA will only review the NDA if it is sufficiently complete to permit the FDA to conduct a substantive review on the merits of the application. If the FDA chooses to conduct the review, under the Prescription Drug User Fee Act (“PDUFA”), it has 180 days from the date of a filing to either approve the drug or send the sponsor a confidential statement [339]*339of the FDA’s reasons for denying the application. This confidential statement is known as a Complete Response Letter (“CRL”). If the sponsor receives a CRL, it may resubmit the NDA at a later date.2

Prior to the 180-day deadline for approving the drug candidate, the FDA may elect to convene an advisory panel to make technical recommendations related to an application and/or to publicly comment on any controversies relating to the drug candidate. Such an advisory committee meeting is the only occasion on which the FDA is permitted to publicly communicate concerns about an NDA.

B. Hemispherx

Hemispherx is a Philadelphia-based, development-stage pharmaceutical company with one drug that generates significant revenues: Ampligen. Ampligen was developed by Carter in 1;he 1970s while a university researcher, and, since at least 1988, Hemispherx has pursued FDA approval of Ampligen as a treatment for chronic fatigue syndrome (“CFS”).

Hemispherx is a public company and its stock is traded on a national exchange.

C. Ampligen Trials

In 1990 and 1991, Hemispherx conducted a placebo-controlled, proof-of-concept trial for Ampligen known as AMP 502. With AMP 502, Hemispherx aimed to demonstrate Ampligen improved participants’ quality-of-life and physical endurance. The trial, however, deviated from its pre-specified protocol in at least six ways: (1) failing to determine a statistical analysis plan until after the study was unblinded; (2) switching from a 48-week trial to a 24-week trial midstream, without proof that the switch did not violate the study blind; (3) including only 92 participants in the trial instead of 100 participants as speei-fied; (4) excluding an additional seven participants in evaluating the data from the endurance test; (5) using some participants’ best performances and others’ worst performances when evaluating the quality-of-life test; and (6) failing to demonstrate that there were no participants in the trial who the trial protocol required to be excluded. According to the complaint, Hem-ispherx was aware of these flaws and the possibility that they compromised the study’s statistic and scientific validity.

In 1997, Hemispherx began a second placebo-controlled clinical trial of Ampli-gen, this one known as AMP 516. AMP 516 was designed as a 40-week trial with twin primary goals of showing Ampligen improved patients’ quality-of-life and physical endurance. Like AMP 502, the AMP 516 trial deviated from its protocol, including: (1) changes to trial parameters over the course of the study; (2) failing to establish controls that would avoid reporting false positive results; (3) failing to calculate results in accordance with the trial protocol; (4) failure of the study blind; and (5) abandoning the statistical analysis technique specified in the protocol when it failed to demonstrate Ampligen improved participants’ endurance. Meanwhile, under any analysis, AMP 516 failed to demonstrate Ampligen improved participants’ quality-of-life. Some participants in AMP 516 were included in a 24-week continuation study known as AMP 516C, in which participants received Ampligen even if they had received placebos in AMP 516. A comparison between the results for patients who received placebos in AMP 516 but Ampligen in AM P 516C and the results for patients who received Ampligen in AMP 516 tended to show Ampligen was ineffective.
