Fig. 3: Treatment-effect estimates derived from experimental arm vs concurrent control arm or hybrid control arm.

Treatment efficacy was assessed via (A) DCR, (B) PFS, and (C) OS endpoints comparing the MORPHEUS experimental arm (atezolizumab + isatuximab) to the concurrent-control arm or the hybrid-control arm (regorafenib), separately. CC concurrent control, DCR disease control rate, EC external control, HC hybrid control, HR hazard ratio, OR odds ratio, OS overall survival, PFS progression-free survival, SMRW Standardized mortality ratio weighting.
