This is a very impressive signal in a notoriously difficult population—seeing a 79% response rate and median progression-free survival (PFS) of 15.4 months in true extramedullary, triple-class–exposed myeloma is better than expected. Toxicity is real and management-intensive, but the depth and durability of response make this dual-bispecific approach feel like a meaningful advance.
CAR-T therapy outperformed standard of care (SOC) as a second-line treatment, with progression-free survival (PFS) not reached in the CAR-T group compared to 6.2 months in the SOC group. Despite two-thirds of patients crossing over, CAR-T still demonstrated a three-year overall survival rate of 63%, versus 52% with SOC. These are impressive and durable results. The SOC regimen consisted of three cycles of chemoimmunotherapy followed by high-dose chemotherapy and autologous stem cell transplant. This positions CAR-T as a viable second-line option for eligible patients.
Guess who’s coming as an option beyond AI (OBI)? Yes—this study showed no safety concerns and demonstrated comparable efficacy.
The AQUILA trial compared daratumumab to active monitoring in high-risk smoldering multiple myeloma, demonstrating a significant improvement in progression-free survival (PFS) (84% vs 54% at 48 months) and a trend toward better overall survival (OS) (94% vs 86% at 48 months). Dara also achieved a higher rate of deep responses, with 60% of patients reaching minimal residual disease (MRD) negativity compared to none in the monitoring arm. This looks like a game-changer to delay progression, but we’ll need to weigh the toxicity profile carefully in practice and wait for survival data.
