Cooley Wins Securities Litigation Appeal for Talphera

August 20, 2025

Cooley secured a key appellate win on behalf of Talphera (formerly known as AcelRx Pharmaceuticals), a Silicon Valley-based specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in the medically supervised setting, in affirming the 2024 dismissal of a securities class action brought by investors, who alleged that the company committed securities fraud in the run-up to a February 2021 US Food and Drug Administration (FDA) warning letter concerning some marketing materials for its pain drug Dsuvia. 

The case is Sneed v. Talphera, Inc. before the US Court of Appeals for the Ninth Circuit (Case No. 24-3560).

The appeal was argued by Cooley special counsel Patrick Hayden. The Talphera securities litigation team was led by Cooley partners Tijana Brien, Patrick Gibbs and Shannon Eagan, with associates Janelle Fernandes, Allison O’Neill and Greg Merchant.
