A Phase 1b/2 Study of GC012F, a Chimeric Antigen Receptor T-cell (CAR T) Therapy Targeting CD19 and B-cell Maturation Antigen (BCMA) in Subjects With Relapsed/Refractory Multiple Myeloma

Description

This trial is a phase 1b/2, open-label, multicenter study of GC012F, a CD19/BCMA dual CART-cell therapy, in adult subjects with relapsed/refractory Multiple Myeloma.For Phase Ib It aims to evaluate the safety, tolerability, pharmacokinetic characteristics, pharmacodynamic effect, immunogenicity in subjects with relapsed/ refractory Multiple Myeloma, and determine the recommended Phase 2 dose of GC012F. For Phase 2, it aims to evaluate the efficacy, to further characterize the safety of GC012F, pharmacodynamic effect, and immunogenicity, changes from baseline for subject-reported health-related quality of life, overall health status in subjects with relapsed/ refractory Multiple Myeloma.

Trial Eligibility

Inclusion Criteria: * Males and females ≥18 years of age at the time of consent * Written informed consent in accordance with federal, local, and institutional guidelines * Have an ECOG performance status of 0 or 1 * Documented diagnosis of MM per IMWG diagnostic criteria * Received at least three prior MM treatment lines of therapy * Have received as part of their previous therapy a PI and IMiD and an antiCD38 antibody. * Have documented evidence of progressive disease by the IMWG criteria. * Subjects must have measurable disease at screening, as defined by any of the following: serum monoclonal paraprotein (M-protein) ≥1.0g/dL (10 g/L); urine M-protein ≥200 mg/24 h; serum FLC assay: involved FLC level is ≥10 mg/dL (100 mg/L) and serum kappa lambda FLC ratio is abnormal. * Adequate bone marrow and organ function assessment at screening according to the hematological, hepatic, and renal parameters listed in the CSP Exclusion Criteria : • Diagnosed or treated for invasive malignancy other than multiple myeloma, except: Malignancy treated with curative intent and with no known active disease present for ≥2 years before enrollment; or * Adequately treated non-melanoma skin cancer without evidence of disease. * The following cardiac conditions: * New York Heart Association (NYHA) stage III or IV congestive heart failure * Myocardial infarction or coronary artery bypass graft (CABG) ≤6 months prior to enrollment * History of clinically significant ventricular arrhythmia or unexplained syncope, not believed to be vasovagal in nature or due to dehydration * History of severe non-ischemic cardiomyopathy * Received either of the following: * An allogenic stem cell transplant within 6 months before apheresis. Subjects who received an allogeneic transplant must be off all immunosuppressive medications for 6 weeks without signs of graft-versus-host disease (GVHD). * An autologous stem cell transplant ≤12 weeks before apheresis * Known active, or prior history of central nervous system (CNS) involvement or exhibits clinical signs of meningeal involvement of multiple myeloma. * Plasma cell leukemia at the time of screening (\>2.0×109 /L plasma cells by standard differential), Waldenström's macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes), or primary AL amyloidosis.
