Opinion

UNITED STATES DISTRICT COURT AT TACOMA BRIAN COURTER, et al., CASE NO. C21-5190 BHS Plaintiff, ORDER v. CYTODYN, INC., et al., Defendants.

THIS MATTER is before the Court on defendants CytoDyn, Inc., Michael Mulholland and Scott Kelly’s motion to dismiss plaintiff Brian Courter,1 et al.’s second amended class action complaint, Dkt. 116. Defendant Pourhassan joins the motion, Dkt. 123. The putative plaintiff class asserts four Securities Act claims based on the defendants’ allegedly false and misleading statements about CytoDyn’s Investigational 1 There are six named plaintiffs, all seeking to represent a class of similarly situated purchasers of CytoDyn stock during the Class Period, between March 27, 2020, and March 30, 2022. This Order refers to the plaintiffs as “Courter” in the singular for clarity and ease of reference, unless the context requires otherwise. New Drug (IND), “Leronlimab.” Defendants move to dismiss the bulk of Courter’s claims.

CytoDyn2 is a Vancouver, Washington based biotechnology company. Its primary drug candidate is Leronlimab, which it describes as a “humanized monoclonal antibody” that it is developing for a variety of potential uses. Dkt. 116 at 7. Mulholland was CytoDyn’s Chief Financial Officer (CFO) from December 2012 to May 2021. Kelly was a CytoDyn director, Chairman of the Board, and Chief Science Officer over time, from

April 2017 to December 19, 2022. Nader Pourhassan was the CEO, president, and a member of the board from 2101 to January 2022. Courter alleges that CytoDyn, Pourhassan, Mulholland, and Kelly materially misled investors about the progress and success of its ongoing efforts to obtain FDA approval for use of its sole drug, “Leronlimab,” as a treatment for HIV and, later, for

COVID-19. Courter alleges CytoDyn made false statements and failed to disclose important information to increase CytoDyn’s stock price, and that he was damaged when the price fell because the true, dismal state of those efforts was revealed. Courter alleges CytoDyn’s false statements arose in two overlapping contexts, over two years. The first context is CytoDyn’s efforts to persuade the market that its HIV

“biologic license application (BLA)” to the FDA was complete and that approval was imminent, to prop up CytoDyn’s stock price. Courter contends that CytoDyn misled 2 The Order similarly refers to all four named defendants as “CytoDyn” except where the context requires otherwise. investors about its lengthy efforts to obtain FDA approval for Leronlimab as an HIV treatment. He contends CytoDyn publicly stated on April 27, 2020, that the HIV BLA was “complete” when it was not; CytoDyn had not provided data, information and

analyses the FDA had already told CytoDyn was required. Courter alleges the FDA privately told CytoDyn on April 29, 2020, that its BLA submission was not complete and asked it to “take responsibility for the misinformation.” Dkt. 132 at 14 (citing Courter’s second amended complaint, Dkt. 103, at 41). Courter alleges that the stock price spiked because of CytoDyn’s announcement,

and that Pourhassan and Kelly exercised options to sell stock for almost $19 million between April 30 and May 4, 2020. CytoDyn did not acknowledge that its HIV BLA was in fact incomplete until May 4, which Courter contends predictably sent the stock price back down. CytoDyn supplemented its HIV BLA submission in May and told investors that the BLA was now complete, even though it knew it lacked the required safety and

dosage data. On July 8, 2020, the FDA sent CytoDyn a nonpublic “Refuse to File (RTF)” letter, explaining that the May submission “had numerous omissions and inadequacies so severe as to render the application incomplete[.]” Dkt. 132 at 14 (citing Dkt. 103 at 45–46). Courter alleges that the letter meant that CytoDyn could not submit a complete HIV BLA

without conducting an additional clinical trial. CytoDyn publicly announced it had received the RTF letter, but Courter alleges it knowingly misrepresented the letter’s contents and its ability to timely resubmit the BLA. Id. On July 13, 2020, CytoDyn issued a Press Release (and held an investment community conference call) asserting that the FDA would not require more clinical trials, and that CytoDyn was “confident it can provide all information requested by the FDA.” See Dkt. 177 at 24–28 and 30–48. Courter asserts that these statements were knowingly false.

The second context for CytoDyn’s allegedly false statements relates to its efforts to obtain FDA approval to use Leronlimab as an Investigational New Drug (IND) to treat COVID-19. Courter’s claims arise primarily from statements related to its early emergency IND (eIND) use, and two subsequent clinical trials, CD10 and CD12. CytoDyn released the results of CD10 at the end of July 2020. While the study missed its

primary endpoint, Courter asserts that CytoDyn falsely assured investors that the “more important” and “statistically significant” results for the National Early Warning Score2 (NEWS2) scale secondary endpoint demonstrated that Leronlimab was effective and that CytoDyn had “requested Emergency Use Authorization (EUA)” based on the results of CD10. Dkt. 132 at 15. Courter contends that these statements were false; CytoDyn knew

the NEWS2 data was instead clinically meaningless, that CD10 did not support further FDA action, and that CytoDyn had not requested EUA. CytoDyn admitted this latter point on September 16, 2020, and the stock declined. Id. Courter contends that CytoDyn’s efforts continued with a second clinical trial, CD12, which tested Leronlimab’s efficacy for critically ill COVID-19 patients. He

alleges CytoDyn “unblinded” this clinical trial on February 12, 2021, and that CD12 missed all its endpoints. Nevertheless, CytoDyn sent the FDA an Executive Summary seeking EUA for critically ill COVID-19 patients based on analysis of CD12 subgroups four days later. On February 18, the FDA denied the EUA because the subgroup analyses did not support efficacy and CytoDyn’s emphasis on favorable trends in them was “potentially misleading.” Id. CytoDyn revised and resubmitted its request for EUA on February 23. On February 25, the FDA responded that CD12 was not sufficient to

support EUA and that the trial did not demonstrate Leronlimab’s efficacy. Id. Courter alleges that CytoDyn told investors about the CD12 results on March 8, 2021, and the stock price declined. But CytoDyn also told investors that CD12 demonstrated Leronlimab was effective and that it had sought EUA. Courter alleges that the FDA issued in response a “devastating” “Statement on Leronlimab” on May 17,

2021, explaining that the currently available data did not support the clinical benefits of Leronlimab for COVID-19. Dkt. 117 at 5. He asserts that CytoDyn nevertheless continued to falsely represent to investors that the drug was on a path to FDA approval, and Pourhassan falsely told investors that none of CytoDyn’s prior statements were inconsistent with the FDA’s Statement. Dkt. 132 at 16.

Courter contends that CytoDyn continued to publicly, and falsely, claim that the FDA was not requiring another clinical trial for the HIV BLA, and that CytoDyn already had the data needed to complete the BLA. Id. Instead, he claims, CytoDyn and its officers had internally recognized that they did not have the necessary data, and that they would need another trial—a process complicated further by the fact that it had lost access to
