About 15 months after ending development of a different hereditary angioedema candidate due to liver safety worries, KalVista Pharmaceuticals, Inc. reported what analysts called best-case scenario results for its Phase III oral kallikrein inhibitor sebetralstat (KVD900) on 13 February. With the data in hand, KalVista said it plans to file sebetralstat for on-demand therapy in HAE by midyear, with expectations that it might become a foundational treatment for the rare swelling disorder.
