Corcept Seeks to Block Ex-Judge’s Testimony in Teva Antitrust
Corcept Therapeutics (CORT) is challenging the testimony of retired judge Kathleen O’Malley in its ongoing antitrust lawsuit with Teva Pharmaceutical (TEVA). Corcept argues O’Malley’s testimony improperly addresses legal questions for the jury. Teva accuses Corcept of using patent litigation to block generic competition for its drug Korlym, seeking financial compensation and injunctive relief. The trial is scheduled for March 2027, with Corcept denying the allegations.
