UNITED STATES DISTRICT COURT DISTRICT OF CONNECTICUT TONYA HILLS and OKLAHOMA LAW ) 3:23-CV-915 (SVN) ENFORCEMENT RETIREMENT ) SYSTEM, individually and on behalf of all ) others similarly situated, ) Plaintiffs, ) ) v. ) ) BIOXCEL THERAPEUTICS, INC., ) September 29, 2025 VIMAL MEHTA, RICHARD ) STEINHART, and ROBERT RISINGER, ) Defendants. ) RULING ON DEFENDANTS’ MOTION TO DISMISS THE SECOND AMENDED COMPLAINT AND PLAINTIFFS’ MOTION FOR LEAVE TO FILE A THIRD AMENDED COMPLAINT Sarala V. Nagala, United States District Judge. In this securities fraud putative class action, Plaintiffs Tonya Hills (“Hills”) and Oklahoma Law Enforcement Retirement System (“OLERS”), on behalf of themselves and all others similarly situated, assert claims against Defendants BioXcel Therapeutics, Inc. (“BioXcel” or the “Company”), Vimal Mehta (BioXcel’s Chief Executive Officer), Richard Steinhart (BioXcel’s Chief Financial Officer), and Robert Risinger (BioXcel’s Chief Medical Officer) (together the “Individual Defendants,” and, with BioXcel, “Defendants”). Plaintiffs allege that between March 9, 2023, and August 11, 2023, Defendants made materially misleading disclosures which caused the artificial inflation of BioXcel’s stock value, in violation of Section 10(b) of the Securities Exchange Act, 15 U.S.C. § 78j(b), and Section 20(a) of the Exchange Act, 15 U.S.C. § 78t(a), and that they suffered losses when those disclosures were corrected and the stock’s value fell significantly. Pending before the Court are Defendants’ motion to dismiss Plaintiffs’ second amended complaint and Plaintiffs’ motion for leave to file a third amended complaint that maintains the allegations of the second amended complaint and adds additional factual allegations. As discussed at the oral argument on the motions, the Court has applied Defendants’ arguments for dismissal of the second amended complaint to Plaintiffs’ third amended complaint, in addition to considering

Defendants’ arguments regarding futility asserted in the briefing associated with the motion for leave to amend. It concludes that Plaintiffs have plausibly pleaded their claims for securities fraud in the third amended complaint, with respect to certain statements made by Defendants. Accordingly, for the reasons that follow, Defendants’ motion to dismiss the second amended complaint is DENIED AS MOOT and Plaintiffs’ motion for leave to file the third amended complaint is GRANTED IN PART. I. PROCEDURAL HISTORY Plaintiffs initiated this putative class action on July 7, 2023. Complaint, ECF No. 1. Following the Court’s appointment of Plaintiffs Hills and OLERS as co-Lead Plaintiffs and of lead

class counsel, see Order, ECF No. 79, Plaintiffs filed an amended complaint on December 5, 2023, see Am. Compl., ECF No. 90, which Defendants sought to dismiss, see Mot. to Dismiss, ECF No. 106. The Court granted Defendants’ motion to dismiss the amended complaint, finding that although Plaintiffs had pleaded sufficient facts to support the determination that two of Defendants’ statements were misleading, Plaintiffs failed to sufficiently allege scienter. Hills v. BioXcel Therapeutics, Inc., No. 3:23-CV-915 (SVN), 2024 WL 3374145 (D. Conn. July 11, 2024). Plaintiffs then filed a second amended complaint, see Second Am. Compl., ECF No. 130, which Defendants again sought to dismiss, see Second Mot. to Dismiss, ECF No. 134. While that motion to dismiss was pending, Plaintiffs filed a motion for leave to file a third amended complaint, see Pls.’ Mot. to Amend/Correct, ECF No. 141, which Defendants opposed on grounds of futility only, see Defs.’ Opp’n, ECF No. 143. II. FACTUAL BACKGROUND Plaintiffs’ proposed third amended complaint, ECF No. 142-1, alleges the following facts, which are taken as true for purposes of a motion to dismiss, Ashcroft v. Iqbal, 556 U.S. 662, 678

(2009), and by extension, for the purposes of the futility standard used to assess a motion for leave to amend, Lucente v. Int’l Bus. Machines Corp., 310 F.3d 243, 258 (2d Cir. 2002) (“An amendment to a pleading is futile if the proposed claim could not withstand a motion to dismiss pursuant to Fed. R. Civ. P. 12(b)(6).”). BioXcel is a clinical stage biopharmaceutical and biotechnology company that focuses on finding new therapeutic uses for pre-existing drugs through, among other methods, artificial intelligence. ECF No. 142-1 ¶¶ 1, 87–89. BioXcel’s repertoire includes four chemical compounds, but its most advanced research and development plans relate to BXCL501, a chemical compound that can be used to treat agitation in various patient populations and that is approved to treat

agitation in patients with schizophrenia and bipolar disorders. Id. ¶¶ 90–92. During the Class Period, BioXcel’s leadership team included Defendants Vimal Mehta as Chief Executive Officer (“CEO”), Richard Steinhart as Senior Vice President and Chief Financial Officer, and Robert Risinger as Chief Medical Officer of Neuroscience. Id. ¶¶ 15–17. A. TRANQUILITY II Clinical Trial In December of 2021, BioXcel announced that it was embarking on a “pivotal Phase III trial,” TRANQUILITY II and TRANQUILITY III, as part of its effort to secure FDA approval for BXCL501 to be used to treat agitation in patients with Alzheimer’s disease. Id. ¶¶ 2, 95, 97, 109– 12. The TRANQUILITY II clinical trial was designed in consultation with the FDA and required 150 participants to ensure the conclusions from the trial would permit researchers to understand “the differences between the test groups and the control groups.” Id. ¶ 99. The trial also included seven specific participant inclusion criteria, which were to be measured, documented, and analyzed before the start of the study, and ten participant exclusion criteria, which were to be assessed before enrollment. Id. ¶¶ 100–04. To fund these research efforts, BioXcel entered into financing agreements with Oaktree

Capital Management, L.P. (“Oaktree”) and Qatar Investment Authority (“QIA”) in April of 2022, which the Company announced in a press release. Id. ¶¶ 122–23. As part of the announcement, BioXcel explained that that these funding agreements would extend its “cash runway” into 2025. Id. But under the terms of the agreements, the funding would become available to BioXcel only “upon satisfaction of certain conditions,” including meeting certain regulatory, financial, and patent-related milestones. Id. ¶¶ 125–28. Among the relevant regulatory milestones was receiving approval “from the FDA of an [New Drug Application] in respect of the use of BXCL 501 for the acute treatment of agitation associated with Alzheimer’s Disease.” Id. ¶ 127. Due to the Company’s financial instability, its need to meet regulatory approval benchmarks in order to pay

back Oaktree and QIA and access additional financing, and its ongoing cash flow issues, the TRANQUILITY trials were essential to BioXcel’s overall success. Id. ¶¶ 2, 120–21, 127–28, 131, 133, 135–39, 141. BioXcel engaged Segal Trials, a “second-rate clinical trial company,” to conduct the TRANQUILITY II and III trials because it believed Segal Trials would ”enable it to speed up the TRANQUILITY II and III trials” and thus allow BioXcel to meet its funding benchmarks. Id. ¶ 139. The principal investigator at the Segal Trials site that enrolled forty percent of the TRANQUILITY II trial participants was Dr. Caitlin Meyer, an inexperienced researcher who had never overseen a clinical trial. Id. ¶¶ 3, 113, 117, 140.
