Phase III Study of OriCAR-017 Anti-GPRC5D CAR-T Therapy in Adults with Relapsed or Refractory Multiple Myeloma

What this Trial Is About

Researchers are evaluating the safety, pharmacokinetics, pharmacodynamics, and preliminary effectiveness of an anti-GPRC5D CAR-T cell product called OriCAR-017 in adults with relapsed or refractory multiple myeloma. This Phase III open-label study is the first clinical trial of OriCAR-017 in the United States by OriCell Therapeutics Co., Ltd., aiming to find suitable dosing and assess early treatment results in this patient group. The study includes a Phase I dose escalation stage with three different doses given as a single intravenous infusion to up to 18 participants. This is followed by a dose expansion stage with 10-15 participants and then a Phase II stage that may include up to 48 participants. Each participant receives one infusion of OriCAR-017 to evaluate its effects and safety. Participants will be closely monitored for up to two years after treatment. Researchers will assess the maximum tolerated dose and dose-limiting toxicities within 28 days after infusion. They will also study how the drug moves through and affects the body, measure response duration, progression-free survival, overall survival, and other response rates. Regular evaluations include laboratory tests, clinical assessments, and safety monitoring throughout the study period.
