Overview

Brief Summary

This is a single arm, open-label, multi-center prospective study to determine the safety and efficacy of GC012F CAR-T cells in patients diagnosed with BCMA+ refractory/relapsed multiple myeloma (r/r MM).

Detailed Description

The main aim of the study is to determine the safety and efficacy of GC012F in r/r MM. GC012F is an autologous dual chimeric antigen receptor T-cell (CAR-T) therapy that targets B-cell maturation antigen (BCMA) and CD19. This study comprises of a Screening Phase (less than or equal to \[\<=\] 28 days prior to apheresis) followed by Apheresis (will occur upon enrollment); Treatment Phase including a conditioning regimen followed by infusion of GC012F and post-infusion assessments from Day 1 to Day 84; and a Post-treatment Phase (Day 85 and up to end of the study). Efficacy will be explored to assessed and safety will be closely monitored during the study.

Eligibility Criteria

Inclusion Criteria

•Patients must have a confirmed prior diagnosis of active multiple myeloma as defined by the updated IMWG criteria;
•Diagnosis of MM with relapsed or refractory disease. Definition of Refractory/relapse:
•Have had at least 3 prior lines of therapy or primary refractory as defined by Consensus recommendations for the uniform reporting of clinical trials: report of the International Myeloma Workshop Consensus Panel
•Prior therapy should include PI and IMiD. Note: Patients should undergone at least have at least complete 1 cycle treatment in each line. Induction with or without hematopoietic stem cell transplant followed by maintenance therapy is considered a single line of therapy.
•Have had at least 2 prior lines of therapy when refractory to both immunomodulatory drug (IMiD) and proteasome inhibitor(PI) (Refractory was defined by IMWG consensus criteria);
•Estimated life expectancy ≥3 months;
•Hemoglobin ≥ 8.0 g/dL;
•Absolute neutrophil count ≥ 0.75\*10E9/L;
•Platelet count ≥ 50\*10E9/L;
•Absolute lymphocyte count ≥ 1\*10E8/L;

Exclusion Criteria

•Accompanied by other uncontrolled malignancies.There are two exceptions to this criterion: Recepted radical therapy carcinoma without activity within 3 years before screening; and fully treated skin non-melanoma;
•Any situations not benefit for subjects to accept or tolerated to planned therapy or understand informed consent; or any situation in which investigators believe that participation in this study is not in the subject's best interests (e.g., harm to health), or any situation that may prevent, limit or confuse the assessment;
•Convulsion or stoke within past 6 months;
•Any instability of systemic disease within 6 months prior to screening, including but not limited to congestive heart failure (New York heart association (NYHA) classification ≥ III), unstable angina, cerebrovascular accident, or transient cerebral ischemic, myocardial infarction,LEVF\< 45% (assessed by an echocardiogram or multi-door circuit scan );
•Patients have central nervous system (CNS) metastases or CNS involvement (including cranial neuropathies or mass lesions and leptomeningeal disease);
•Subjects with positive HBsAg or HBcAb postive and peripheral blood HBV DNA titer is higher than the lower limit of detection of the research institution; HCV antibody positive; HIV antibody positive; syphilis primary screening antibody positive;
•Presence or suspicion of fungi, bacteria, viruses or other infections that are uncontrollable or requiring intravenous treatment;
•Activity of autoimmune diseases (such as crohn's disease, rheumatoid arthritis, systemic lupus erythematosus), orhistory of autoimmune disease within the last 3 years;
•Clinical evidence of dementia or changes of mental state.
•Exist of pulmonary fibrosis;
