Kymera Therapeutics IncCompleted enrollment ahead of schedule for phase IIb study of oral STAT6 degrader KT-621, with positive phase Ib data and FDA Fast Track designation.

Kymera Therapeutics has completed enrollment in its phase IIb BROADEN2 study of oral STAT6 degrader KT-621 for moderate-to-severe atopic dermatitis about six months ahead of schedule, pulling forward pivotal efficacy data to the end of 2026. The company plans to begin phase III studies in atopic dermatitis by mid-2027 pending regulatory discussions, and KT-621 is also being investigated in the phase IIb BREADTH trial for moderate-to-severe eosinophilic asthma with data anticipated in late 2027. The candidate has received Fast Track designation from the FDA for both indications. Kymera had earlier reported positive phase Ib data demonstrating robust STAT6 degradation, reductions in type 2 inflammatory biomarkers, encouraging clinical activity, and a favorable safety profile, supporting its potential as an oral alternative to injectable biologics.
