KalVista Pharmaceuticals Presents Promising Preclinical Data for Oral Factor XIIa Inhibitor Program
– First preclinical data presented for structurally diverse oral Factor XIIa inhibitors -
– Additional Sebetralstat data also presented -
CAMBRIDGE, Mass. & SALISBURY, England--(BUSINESS WIRE)--$KALV--KalVista Pharmaceuticals, Inc. (NASDAQ: KALV), a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of oral, small molecule protease inhibitors, today presented data for its oral Factor XIIa (FXIIa) and plasma kallikrein (PKa) inhibitor programs at the KININ2022 conference in Annecy, France. Presentations for oral FXIIa inhibitors showed that the compounds block the initiation and amplification of the kallikrein kinin system (KKS) in preclinical models. Of note, small molecule FXIIa inhibitors were shown to suppress FXII zymogen enzyme activity, which has been recently implicated as a distinct initiator of KKS activation, and thus may contribute to disease.
“The oral FXIIa inhibitors we are evaluating show great promise by blocking the earliest steps of kallikrein kinin system activation,” said Andrew Crockett, Chief Executive Officer of KalVista. “The discovery of potent, selective, and orally available FXIIa inhibitors may provide novel therapeutic opportunities to treat HAE and other KKS-mediated diseases.”
The following posters were presented at KININ2022:
- Oral factor XIIa inhibition blocks angiotensin converting enzyme inhibitor induced angioedema in mouse. Clermont AC, Murugesan N, Feener EP Link here
- Oral FXIIa inhibitor KV998086 suppresses FXII zymogen mediated Kallikrein Kinin System activation. Murugesan N, Lee DK, Duckworth EJ, Clermont AC, Hampton SL, Feener EP Link here
- Oral sebetralstat (KVD900) provides rapid inhibition of the kallikrein kinin system in patients with HAE. Duckworth EJ, Lee DK, Murugesan N, Rushbrooke L, Hampton SL, Smith M, Yea C, Audhya P, Feener EP Link here
The following presentations occurred at KININ2022:
