MEMORANDUM AND ORDER ON DEFENDANTS’ MOTION TO DISMISS

BURROUGHS, D.J. This is a federal securities class action lawsuit concerning alleged violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, 15 U.S.C. §§ 78j, 78t, and Rule 10b-5, 17 C.F.R § 240.10b-5, by Defendant AVEO Pharmaceuticals (“AVEO” or “the Company”) and certain of its current and former executives, including Michael Bailey, Matthew Dallas, Keith S. Ehrlich, and Michael Needle (together with AVEO, “Defendants”). [ECF No. 39 (“Am. Compl.”)]. Lead Plaintiff Andrej Hornak (“Plaintiff”), individually and on behalf of a putative class, claims that Defendants made false and misleading statements between May 4, 2017 and November 5, 2019 (the “Class Period”), in connection with its efforts to demonstrate the effectiveness of a candidate drug for treating renal cell carcinoma. See [Am. Compl.]. Currently before the Court is Defendants’ motion to dismiss. [ECF No. 51]. For the reasons stated herein, Defendants’ motion, [ECF No. 51], is GRANTED. I. BACKGROUND A. Factual Background For purposes of this motion, the relevant facts are drawn from Plaintiff’s amended complaint, [Am. Compl.], and viewed in the light most favorable to Plaintiff. Ruivo v. Wells

Fargo Bank, N.A., 766 F.3d 87, 90 (1st Cir. 2014). In addition to Plaintiff’s amended complaint, the Court “may consider ‘documents the authenticity of which are not disputed by the parties; . . . documents central to plaintiffs’ claim; [and] documents sufficiently referred to in the complaint.’” Curran v. Cousins, 509 F.3d 36, 44 (1st Cir. 2007) (alteration in original) (quoting Watterson v. Page, 987 F.2d 1, 3 (1st Cir. 1993)). These include AVEO’s filings with the Securities and Exchange Commission (“SEC”) and press releases, which Plaintiff relies on extensively in his amended complaint. See [Am. Compl.]. AVEO is a biopharmaceutical company that, during the Class Period, was developing a once-daily oral medication for the treatment of renal cell carcinoma (“RCC”). [Am. Compl. ¶ 2]. The Company’s lead drug candidate is tivozanib, which is approved for use in the European

Union but is still undergoing clinical trials in the United States in an effort to obtain approval from the Food & Drug Administration (“FDA”). [Id. ¶¶ 2, 134; ECF No. 52 at 6 (stating that “AVEO is in the process of seeking approval” for tivozanib from the FDA)]. Defendant Bailey has referred to tivozanib as “the central focus” of the Company’s strategy, though it also has other drugs in development. [Am. Compl. ¶¶ 53, 56]. Once a pharmaceutical company has gathered “substantial evidence” of a drug’s efficacy and safety, it may submit a New Drug Application (“NDA”) to FDA. [Am. Compl. ¶¶ 34–37]. This “substantial evidence” is obtained through three phases of clinical trials, culminating in Phase 3 clinical trials involving human subjects. [Id. ¶¶ 36–37]. Clinical trials for cancer treatments typically measure two outcomes: overall survival (“OS”), which measures how long a patient lives after treatment, and progression-free survival (“PFS”), which measures how long a patient lives and for how long the disease stops progressing after treatment. [Id. ¶ 43]. OS is measured by patient death, while PFS is measured by imaging tumor size and patient death. [Id.

¶ 43]. Measuring OS takes longer than PFS because, even if a patient has completed treatment, OS cannot be measured until a patient dies. [Id. ¶ 45]. Data on OS and PFS may become impossible to obtain if a subject is “lost to follow-up,” which can mean that they have stopped participating in the trial, have become unreachable, or their data has been lost due to mechanical error. [Id. ¶ 112]. If data on a “lost to follow-up” subject is later identified, that recovered data can potentially change the clinical study results. See [id. ¶¶ 117–18]. OS or PFS can be used as the primary endpoint in a clinical trial for a drug that treats RCC, though the FDA has “routinely considered” OS even when PFS is selected as the primary endpoint for a study. [Id. ¶ 48]. On May 26, 2016, AVEO announced the start of a new Phase 3 clinical trial, TIVO-3, which was designed as a “randomized, controlled, multi-center, open-label study” that would

compare AVEO’s tivozanib to a competitor’s drug, sorafenib. [Am. Compl. ¶ 10]. TIVO-3 was intended to address FDA concerns about the OS of patients from a previous study, TIVO-1. [Id. ¶ 10]. The study was initially designed to enroll 351 subjects who would either be administered tivozanib or sorafenib, though that number later dropped to 322. [Id. ¶¶ 58, 62–63]. The Company announced that the primary endpoint for the study was PFS, with OS as one of several secondary endpoints. [Id. ¶ 62]. The Company also announced that a “topline readout” of study results was “projected” to be available in the first quarter of 2018. [Id.]. Due to a slowdown in PFS events throughout 2018, however, topline analysis was not conducted until the fourth quarter of 2018. [Id. ¶¶ 90, 99].1 As early as June 2017, the Company reported its plan to conduct topline analysis of 255 events, but in October 2018 the Company announced that it would analyze only 242 events due to the slow pace of events and the fact that the reduction in events would not significantly alter their interpretation of the results. [Id. ¶ 74 (stating that the

Company planned to analyze 255 events, which would provide 90% power to the analysis); id. ¶ 88 (stating that the Company would analyze 242 events, decreasing the power of the study from 90% to 88%)]. By November 5, 2018, AVEO disclosed the topline results of the TIVO-3 study, noting that tivozanib had “met its primary endpoint of demonstrating a statistically significant benefit in progression-free survival . . . .” [Am. Compl. ¶ 99]. At the same time, AVEO reported initial OS results, but noted that OS data would not be mature until nearly a year later. [Id. ¶ 209]. The Company announced that its goal was to submit an NDA “in approximately six months,” [id. ¶ 100], and quoted Defendant Bailey as saying that the results were “[the] first step in our goal to improve both outcomes and patient experience,” [id. ¶ 101].

Plaintiff identifies two categories of Defendants’ statements as being materially false and misleading: 1) statements about the timing by which topline data would be available for analysis, and 2) statements made on November 5, 2018 about OS data. [ECF No. 56 at 14 n.3 (waiving claims based on any other alleged misstatements raised in the amended complaint)]. 1. Alleged Misrepresentations During the Class Period a. Statements About the Timing of Topline Data The alleged misstatements were made in quarterly and annual filings submitted to the SEC, as well as in press releases. The first alleged misstatement was made in May 2017 in a

Compl. ¶ 136].
