Conclusion: BCMA/CD19 dual FasT CAR-T GC012F continues to provide deep and durable responses with a favorable safety profile in additional RRMM patients across all dose levels demonstrating a very high MRD-negativity rate, including in patients refractory to anti-CD38, proteasome inhibitors (PI) and immunomodulatory drugs (IMiDs). GC012F is currently being studied in earlier lines of therapy as well as additional indications.
https://www.myeloma.org/videos/phase-1-study-cart-ddbcma-relapsed-orrefractory-multiple-myeloma
Conclusion: To date, CAR T-ddBCMA administration has demonstrated clinical activity, including 100% overall response rate (ORR) with rates of complete response (CR)/stringent complete response (sCR) and ≥ very good partial response (VGPR) of 67% and 88%, respectively. Durable responses beyond 18 months have been observed, including in patients with extramedullary disease (EMD).
