December 25, 2023 updated by: Kai Lin Xu，MD, Xuzhou Medical University

Efficacy and Safety Study of Anti-FcRL5 CAR-T Cells in Subjects With Relapsed and Refractory Multiple Myeloma

This is an open label, single-arm, Phase 2 study to evaluate the efficacy and safety of Anti-FcRL5 CAR-T in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture. Anti-FcRL5 chimeric antigen receptor (CAR) modified T cells. Prior to Anti-FcRL5 infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide.

Detailed Description

This open label, single-arm, Phase 2 study aims to evaluate the efficacy and safety of Anti-FcRL5 CAR-T in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture. Anti-FcRL5 chimeric antigen receptor (CAR) modified T cells. Prior to Anti-FcRL5 infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide. After infusion, the investigators will observe the characteristics of dose limited toxicity (DLT), and determine the maximum tolerable agent MTD and rp2d were confirmed. To provide basis for the dosage and treatment plan of cell products in follow-up clinical trials.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures
