Study Evaluating Safety and Efficacy of UCART Targeting CS1 in Patients With Relapsed/Refractory Multiple Myeloma



This is a Phase I, FIH, open-label, dose escalation study evaluating safety and efficacy of UCART targeting CS1 in patients with relapsed or refractory multiple myeloma (MM). The purpose of this study is to evaluate the safety and clinical activity of one infusion of UCARTCS1A and to determine the Maximum Tolerated Dose (MTD).

May 5, 2023: Cellectis has given up on its multiple myeloma CAR-T candidate UCARTCS1. With the phase 1 clinical trial two years behind schedule, and heavy investment needed to accelerate enrollment, the off-the-shelf cell therapy specialist is stopping the study and focusing its resources on three other candidates.
