NCT ID: NCT03931421

Last Updated: 2019-06-04

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE2
• Total Enrollment: 30 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-07-31
• Study Completion Date: 2022-12-31

Brief Summary

It's a single arm, open label prospective study, in which the safety and efficacy of B Cell Maturation Antigen（BMCA）-targeted CAR-T thearpy are evaluated in refractory/relapsed multiple myeloma patients.

Detailed Description

In this trial, T cells are seperated from multiple myeloma patients, and engineered into BMCA-targeted CAR-T cells, these cells are then transfused back into the patients to elimimnate the myeloma cells. In this process, the safety and efficacy of this CAR-T treatment are closely monitored.

Conditions

Multiple Myeloma

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

experiment group

In this arm, patients are treated with B Cell Maturation Antigen (BMCA)-targeted CAR-T cells and the safety and efficacy will be observed.

Group Type: EXPERIMENTAL

CAR-T treatment

Intervention Type: BIOLOGICAL

a novel method for treatment of multiple myeloma, in which patients' T cells are engineered into B Cell Maturation Antigen（BMCA）-Targeted CAR-T cells to eliminate myeloma cells.
