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.
This trial is currently open and accepting patients.
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, pharmacokinetic characteristics, 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.
The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.
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.

Results: As of data cutoff (DCO) on 18 July 2025, a total of 25 pts received infusion of AZD0120 (n=12 DL1; n=13 DL2). The median age was 64 y (range 44–78), median pLOT was 4 (range 3–7), 72% were triple-class refractory, 20% had prior BCMA CAR T-cell therapy, 4% had prior teclistamab, 28% had high-risk cytogenetic features [del(13q), del(17p13), t(4;14), t(14;16), amp(1q)], and 8% had extramedullary plasmacytomas. The median time from apheresis to release was 14 d (range 10–30). Median time from apheresis to infusion was 28 d (range 19–44) with 5 pts receiving bridging therapy. Median follow-up was 1.4 mo (range 0–19.3). No dose-limiting toxicities were reported for either dose. The most common treatment-emergent AEs (TEAEs, any grade) were CRS (64%), neutrophil count decreased (56%), and anemia (32%). The most common grade ≥3 TEAEs were neutrophil count decreased (52%), lymphocyte count decreased (32%), and white blood cell count decreased (32%). CRS was reported in 75% of pts at DL1 (all grade 1) and 54% at DL2 (46% grade 1; 8% grade 2), with no cases of grade ≥3 CRS. Median time to CRS onset (DL1/DL2) was 9 d (range 2–11), with a median duration of 2 d (range 1–4); 12 pts (48%) received tocilizumab for CRS management and 12% received dexamethasone. No cases of ICANS, related non-ICANS neurotoxicity, IEC-colitis, or secondary primary malignancies have been reported. There have been no deaths. For efficacy-evaluable patients (n=15), ORR was 100% (33% sCR, 47% VGPR, 20% PR). CR rates in evaluable pts were 30% in DL1 (n=10) and 40% in DL2 (n=5); median time to response was 0.9 mo for both DLs (range 0.9–1.9 DL1; 0.6–1.8 DL2). All MRD-evaluable pts (n=5 DL1; n=3 DL2; DCO 01 July 2025) were MRD-negative by NGS at a sensitivity of 10 -5 . Three pts in DL1 with ≥12 mo follow-up maintained MRD negativity. Consistent with robust in vivo expansion, CK analysis from 16 evaluable pts (DCO 12 June 2025) demonstrated a median Tmax of 13 d post-infusion with a median Cmax of 85,266 copies/mg gDNA. Median persistence was 42 d (range 13–273). Updated clinical data with additional follow-up will be presented.
Conclusion: Preliminary phase 1b results demonstrated AZD0120 was well tolerated, with a low incidence of serious AEs, no grade ≥3 CRS, and no ICANS. FasTCAR-manufactured AZD0120 had expected in vivo expansion, which may have resulted in the predictable CRS profile. A single infusion of AZD0120 achieved early, deep responses with 100% MRD negativity from 4L+ triple-class‒exposed pts with RRMM.
