KalVista Secures FDA Approval for First Oral On-Demand Hereditary Angioedema Treatment
SHERIDAN, WYOMING – July 8, 2025 – KalVista Pharmaceuticals has received U.S. FDA approval for its oral treatment Ekterly (sebetralstat), marking a major milestone as the first and only on-demand tablet therapy for hereditary angioedema (HAE) in patients aged 12 and older.
The company confirmed that the drug will be available in the U.S. “immediately” under the brand name Ekterly. According to KalVista’s press release, it is “the first and so far only oral and on-demand treatment for hereditary angioedema (HAE).”
Regulatory delays and internal agency tensions
Ekterly’s road to approval was not smooth. Last month, the FDA informed KalVista that it would not meet its original target action date of June 17, citing “heavy workload and limited resources,” according to the biotech’s announcement at the time.
