Climb Bio Reports CLYM116 Phase 1 Data Supporting 12-Week Dosing
Climb Bio reported Phase 1 results for CLYM116, showing sustained APRIL suppression through 12 weeks and reductions in IgA and Gd-IgA1. A single dose of at least 480 mg suppressed free APRIL by 90% or more, supporting a potential every-12-week regimen. The antibody was generally well tolerated. Phase 2 trial is enrolling, with initial data expected in the first half of 2027, and a Phase 3 trial is expected to begin in 2027, pending regulatory feedback.
