KalVista Pharmaceuticals Inc.

Company Overview

Business Model: KalVista Pharmaceuticals, Inc. is a global biopharmaceutical company focused on the discovery, development, and commercialization of life-changing oral therapies for rare diseases with significant unmet needs. The company's primary revenue generation mechanism is expected to be through the commercialization of EKTERLY (sebetralstat), its novel, orally delivered, small molecule plasma kallikrein inhibitor, for the treatment of acute attacks of hereditary angioedema (HAE). The company also aims to generate revenue through commercialization partnerships in international markets and by developing a sustainable pipeline of new drug candidates.

Market Position: KalVista Pharmaceuticals, Inc. has achieved a significant market position with the U.S. Food and Drug Administration (FDA) approval of EKTERLY (sebetralstat) on July 3, 2025, making it the first and only oral, on-demand therapy for HAE. This differentiates it from all prior on-demand HAE treatments, which required intravenous or subcutaneous administration. The company believes EKTERLY (sebetralstat) has the potential to fundamentally shift HAE management by enabling earlier treatment and reducing treatment burden. HAE is a rare genetic condition affecting approximately 1 in 35,000 to 1 in 50,000 people.
