KalVista Pharmaceuticals Inc. has announced new data from its KONFIDENT and KONFIDENT-S studies of EKTERLY® (sebetralstat), the first oral on-demand treatment for hereditary angioedema $(HAE)$. The findings were presented at the 20th German Allergy Congress in Düsseldorf, Germany, held from October 2-4, 2025. Results from the studies demonstrated that sebetralstat enabled rapid and effective treatment of HAE attacks among European participants, with a median time to treatment of 16 minutes and a median time to beginning of symptom relief of 1.6 hours. The KONFIDENT-S interim analysis included 69 participants from 15 European countries who collectively treated 999 attacks. The data also highlighted barriers associated with injectable therapies, such as injection-site reactions and difficulty accessing medication, based on a patient survey. EKTERLY is now approved in the European Union, with a launch planned in Germany this quarter and additional European launches expected in 2026 and beyond.
