The Delhi High Court has temporarily barred Zydus Lifesciences from selling its breast cancer drug Sigrima, a biosimilar of Roche's Perjeta (pertuzumab), due to a patent infringement lawsuit filed by Roche. The court granted an interim injunction against Zydus after Roche argued that Sigrima and another biosimilar, Womab from Dr Reddy's, violate its patents. Zydus had received conditional approval for its pertuzumab biosimilar but launched it amidst ongoing litigation, prompting the court to intervene to prevent potential market disruption.
