After delaying a June PDUFA date, the U.S. FDA has approved Kalvista Pharmaceuticals Inc.’s Ekterly (sebetralstat) for hereditary angioedema (HAE) in those aged 12 and older. The plasma kallikrein inhibitor now joins a market with previously approved drugs for the rare, genetic, life-threatening condition, as well as other companies with HAE drugs in development. Ekterly is the first orally-delivered on-demand treatment, as all others in the U.S. are intravenously or subcutaneously administered.
