A Study of GC012F (AZD0120), a CAR T Therapy Targeting CD19 and BCMA in Subjects With Relapsed/Refractory Multiple Myeloma

This trial is a phase 1b/2, open-label, multicenter study of GC012F (AZD0120), 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 (AZD0120).

For Phase 2, it aims to evaluate the efficacy, to further characterize the safety of GC012F (AZD0120), 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.

Eligibility Criteria:
Inclusion 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
