What Is The Lawsuit About? The complaint filed alleges that, between February 27, 2025 and May 26, 2025, Defendants failed to disclose to investors that: (1) Rocket knew SAEs, including death of participants enrolled in the study, were a risk; (2) Rocket amended the trial's protocol to introduce a novel immunomodulatory agent to the pretreatment regimen without providing this critical update to shareholders; and (3) as a result, Defendants' positive statements about the Company's business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
