Dr. Reddy’s (NYSE: RDY) partner halts TACTI-004 Phase III Eftilagimod alfa trial
Dr. Reddy’s Laboratories announced that its partner, Immutep, has halted the TACTI-004 Phase III trial of Eftilagimod alfa for non-small cell lung cancer due to an independent data monitoring committee's recommendation after a futility analysis. This decision leads to the discontinuation of the trial, an enrollment halt, and a wind-down process. Dr. Reddy’s subsidiary, which holds commercial rights in several territories, has only made the upfront payment and is discussing next steps with Immutep, whose broader pipeline for Eftilagimod alfa remains in focus.
