KalVista Pharmaceuticals Inc. recently announced the presentation of new data at the European Academy of Allergy and Clinical Immunology Congress 2025 in Glasgow, United Kingdom. The data focus on the efficacy of sebetralstat for the on-demand treatment of hereditary angioedema $(HAE)$ attacks among patients receiving long-term prophylaxis. The KONFIDENT-S study highlighted the challenges of adherence to long-term prophylaxis and the need for effective on-demand treatments. Results showed that oral sebetralstat provided rapid relief for breakthrough attacks, with a median time to symptom relief of 1.3 hours. These findings were presented at the congress, indicating the potential of sebetralstat as a complementary treatment to existing long-term prophylaxis options.
