KalVista Pharmaceuticals, Inc.

The Innovation Passport is the first step in the UK’s Innovative Licensing and Access Pathway (ILAP), which is designed to accelerate a product’s time to market and facilitate patient access to innovative medicines.

“As a company which has its roots in the UK, we are pleased to receive the ILAP designation, which will enable us to further accelerate our regulatory submission for sebetralstat,” said Andrew Crockett, Chief Executive Officer of KalVista. “We look forward to collaborating with the MHRA and other health regulatory agencies worldwide as we continue to work towards bringing the first oral, on demand treatment to people living with HAE.”

KalVista recently provided topline phase 3 data for sebetralstat, which displayed clinically and statistically significant results across all endpoints, and an excellent safety and tolerability profile. The Company will be presenting late-breaking KONFIDENT trial data on February 25, 2024, at the upcoming American Academy of Allergy, Asthma & Immunology (AAAAI) Annual Meeting.
