KalVista inks Japan licensing deal for HAE drug sebetralstat

CAMBRIDGE, Mass. & TOKYO – KalVista Pharmaceuticals, Inc. (NASDAQ:KALV) has entered into a licensing agreement with Kaken Pharmaceutical Co., Ltd. (JPX: 4521.T) to commercialize sebetralstat in Japan, a potential first oral treatment option for hereditary angioedema (HAE). Under the agreement, KalVista will receive an upfront payment of $11 million, with the potential for an additional $11 million upon regulatory approval, plus royalties from sales.

The partnership leverages Kaken's regional expertise in bringing innovative therapies to market, aiming to address the unmet medical needs of the HAE community in Japan. KalVista's CEO, Ben Palleiko, expressed confidence in Kaken's capabilities to successfully launch sebetralstat, which is part of the company's strategy to expand the drug's global reach. The market has responded positively to KalVista's developments, with the stock showing a strong 35% year-to-date return. InvestingPro analysis reveals that 7 analysts have revised their earnings expectations upward for the upcoming period, suggesting growing confidence in the company's prospects.

Sebetralstat has been granted Orphan Drug Designation by Japan's Ministry of Health, Labour and Welfare, with a New Drug Application currently under review. If approved, it would be the first oral on-demand treatment for HAE in Japan, providing a significant advancement in the management of this rare condition.

KalVista Pharmaceuticals focuses on developing oral therapies for rare diseases, with sebetralstat as its lead investigational product. The drug is also under regulatory review in the United States, with a Prescription Drug User Fee Act (PDUFA) goal date of June 17, 2025, and has applications pending with the European Medicines Agency and other global regulatory bodies.

Kaken Pharmaceutical specializes in orthopedics and dermatology and is recognized for its innovative pharmaceutical developments in Japan. The collaboration is expected to enhance the quality of life for patients with HAE by introducing an oral treatment alternative.

This licensing agreement is a forward-looking statement and involves risks and uncertainties that may cause actual results to differ.
