The US Food and Drug Administration (FDA) has delayed the assessment of the supplemental biologics licence application (sBLA) of Abecma (idecabtagene vicleucel) for treating heavily pre-treated relapsed or refractory multiple myeloma.

In 2021, the FDA the drug as a fifth-line therapy for relapsed or refractory multiple myeloma. The companies are seeking approval for Abecma as an earlier line of therapy for triple-class exposed multiple myeloma.
Abecma is a B-cell maturation antigen (BCMA) directed chimeric antigen receptor (CAR) T-cell therapy. Abecma鈥檚 sales have been a concern, with 2seventybio downsizing in light of low projected sales.

By GlobalDataAbecma鈥檚 sBLA is supported by the data from the Phase III KarMMa-3 trial (NCT03651128). The study met its primary endpoint by demonstrating improvement in progression-free survival (PFS) and reduction in the risk of disease progression, compared to standard regimens.
As per the results, participants in the Abecma group had a median PFS of 13.3 months at a median follow-up of 18.6 months, compared to the PFS of 4.4 months in the standard regimen group. A complete response was seen in 39% and 5% of the Abecma and standard treatment group participants, respectively.
Grade 3 or 4 adverse events were seen in 93% and 75% of the Abecma and standard treatment group participants, respectively. In the Abecma group, 88% of the participants observed cytokine release syndrome, with grade 3 or higher events seen in 5% of the patients. The final PFS and interim overall survival data from the KarMMa-3 study will be presented at the 2023 American Society of Hematology (ASH) Annual Meeting and Exposition on 11 December.
