San Diego – March 30, 2026 – Cooley secured a dismissal without prejudice for Geron Corporation and its officers in a securities fraud class action arising from the company’s commercialization of its first-in-class blood cancer drug RYTELO. The lawsuit alleged that Geron made material misstatements and false or misleading statements about the company’s preparedness for launch and success commercializing RYTELO. 

On March 30, 2026, Judge Vince Chhabria of the US District Court for the Northern District of California granted the motion to dismiss without prejudice, holding that the plaintiffs failed to adequately allege a plausible inference that Geron intended to defraud investors about its commercial launch progress. The court further held that many of “plaintiffs’ claims do not even come close to surviving dismissal” and noted that the court is “skeptical that the plaintiffs will be able to state a claim” with respect to the vast majority of statements that the plaintiffs alleged were false or misleading.
