Clinical Trial Summary

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 UCARTCS1A and to determine the Maximum Tolerated Dose (MTD).
