High-risk (HR) newly-diagnosed multiple myeloma (NDMM) presents a significant challenge in the field of oncology due to the suboptimal outcomes associated with standard first-line therapies. This is particularly true for transplant-eligible (TE) patients, who despite being candidates for more aggressive treatment approaches, often face a grim prognosis.

GC012F emerges as a beacon of hope in this landscape. It is an autologous CAR-T therapy that uniquely targets both BCMA (B cell maturation antigen) and CD19, two antigens associated with the pathophysiology of multiple myeloma. The dual-targeting approach aims to enhance the efficacy of the treatment by attacking the cancer cells from two fronts, potentially reducing the likelihood of relapse due to antigen escape—a common issue in single-target CAR-T therapies.

The innovation doesn’t stop at dual targeting; GC012F is developed using the novel FasTCAR-T platform. This cutting-edge technology streamlines the manufacturing process of CAR-T cells, enabling next-day production. This rapid turnaround is revolutionary, as traditional CAR-T cell therapies typically require several weeks for cell expansion, during which patients’ conditions may deteriorate.

In the updated results presented in EHA 2024, as of the April 23rd, 2024 data cutoff, patients had a median follow-up of 25.2 months (13.5–35.5). The study showed a 100% overall response rate (ORR) and a stringent complete response (sCR) rate of 95%, with all patients achieving a very good partial response (VGPR). At month 1, all treated patients (100%) across all dose levels achieved minimal residual disease (MRD) negativity. Median duration of response (DOR) and progression-free survival (PFS) were not reached. 

GC120F appeared to be safe as only 27% of patients experienced low-grade cytokine release syndrome (CRS) (5 grade 1 and 1 grade 2), with no grade ≥3 CRS or any observed immune effector cell-associated neurotoxicity syndrome (ICANS).

Robust CAR T-cell expansion was noted in all patients, with a median peak expansion (Cmax) of 62,131 copies/μg DNA and a median time to peak (Tmax) of 10 days (range 9-14 days).

“Patients diagnosed with high-risk newly diagnosed multiple myeloma (NDMM), including those eligible for transplantation, often experience less than optimal outcomes with current treatment standards. GC120F represents a promising ray of hope for these patients.”– MD, United States.

Conclusion 

GC012F is developed based on the Gracell’s FasTCAR next-day manufacturing platform which presents several notable benefits such as decreased waiting periods for patients, cost reduction, and improved fitness of T-cells. Unlike traditional CAR T-cell therapy, where activation, transduction, and ex vivo expansion typically span 1 to 5 weeks post-apheresis and isolation, GC012F utilizing the FasTCAR platform integrates activation and transduction simultaneously within 22 to 36 hours. Expansion occurs inside the patient's body, optimizing conditions. FasTCAR aims to address challenges associated with conventional CAR T-cell therapies, including the prolonged interval between apheresis and infusion, which poses a risk of disease progression. 

Achieving MRD negativity and a 100% ORR across all dose groups is a testament to its potential efficacy. MRD negativity is particularly noteworthy as it indicates no detectable cancer cells remain post-treatment, which is often correlated with improved survival outcomes. The favorable safety profile of GC012F also stands out. 

GC012F has a competitive safety profile as well. Another two approved CAR-T’s ABECMA and CARVYKTI, reports CRS occurs in more than 85% of patients. The manageable safety profile observed with GC012F suggests that it could offer an effective treatment for Multiple Myeloma patients without the high toxicity burden that can complicate patient management and quality of life. At the moment, beyond multiple myeloma, AstraZeneca sees promise for GC012F in other hematologic cancers. GC012F is also being evaluated in several investigator-initiated trials for lupus, and B-cell non-Hodgkin lymphoma.
