In its largest acquisition to date, Chiesi Group is buying Kalvista Pharmaceuticals Inc. for $27 per share, a roughly 40% premium to the previous day’s closing price, putting the total deal value at about $1.9 billion. In return, the Italian pharma firm adds to its rare disease franchise Kalvista’s recently approved hereditary angioedema (HAE) drug, plasma kallikrein inhibitor Ekterly (sebetralstat), which has gotten off to a strong commercial launch as the only orally available, on-demand treatment for HAE.
Biocryst Pharmaceuticals Inc.’s near-term dilution should “pave the way for entrenchment” in the hereditary angioedema (HAE) space, thanks to the buyout of Astria Therapeutics Inc., RBC analyst Brian Abrahams said.
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.
