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.

Biocryst Pharmaceuticals Inc.’s unveiling of real-world data Feb. 24 with its approved Orladeyo (berotralstat) for prophylactic treatment of hereditary angioedema (HAE) brought more attention to the space, due to yield findings from would-be competitors in the near term.

Biocryst Pharmaceuticals Inc. caught some industry observers by surprise early in 2022 when it upped its peak sales estimate for Orladeyo (berotralstat), its oral therapy for prevention of hereditary angioedema attacks, from $500 million to $1 billion. But blockbuster status appears more attainable following the latest setback from a potential competitor, as safety concerns prompted Kalvista Pharmaceuticals Inc. management to ax its phase II study testing KVD-824 in prevention of HAE attacks.

DUBLIN – Glaxosmithkline plc and Anaptysbio Inc. were able to get over some of the disappointment arising from a delayed FDA decision on their PD-1 inhibitor, dostarlimab, earlier this month, as the EMA came through Feb. 26 with a positive recommendation for the drug in endometrial cancers that are deficient in DNA mismatch repair or that are categorized as having high microsatellite instability.

HONG KONG – Japan’s Ministry of Health, Labor and Welfare (MHLW) has granted approval for Biocryst Pharmaceuticals Inc.’s Orladeyo (berotralstat), the first and only drug for prophylactic treatment of hereditary angioedema (HAE) approved in the country. Biocryst’ partner, Torii Pharmaceutical Co. Ltd., will launch the drug after completing pricing negotiations with the Japanese National Health Insurance System (NHI). Tokyo-based Orphanpacific Inc., Biocryst’s representative in Japan, holds the marketing authorization.

As expected, the FDA cleared Biocryst Pharmaceuticals Inc.’s oral, once-daily Orladeyo (berotralstat, formerly known as BCX-7353) for the prevention of hereditary angioedema (HAE) attacks. Last month, Biocryst, as part of its earnings report, said approvals of the compound, a kallikrein inhibitor evaluated by U.S. regulators without an advisory committee meeting, could come in Japan this month and in the EU by the first half of next year.
