Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A prospective, two-cohort, open-label dose-exploration and expansion study to evaluate the safety, tolerability, pharmacokinetics, and antitumor efficacy characteristics of LCAR-M61S and LCAR-M61D in patients with relapsed/refractory multiple myeloma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study was a prospective, two-cohort, open-label clinical study to evaluate the safety, tolerability, pharmacokinetics, and antitumor efficacy characteristics of LCAR-M61S and LCAR-M61D in patients with relapsed/refractory multiple myeloma. All subjects who meet the eligibility criteria will receive intravenous injection of LCAR-M61S or LCAR-M61D cell injection. The study will include the following sequential phases: screening, apheresis, pre-treatment (lymphodepleting chemotherapy), treatment, and follow-up.
