European Medicines Agency Validates Marketing Authorization Application for Oral, Once-Daily Berotralstat (BCX7353) to Prevent HAE Attacks

RESEARCH TRIANGLE PARK, N.C., March 30, 2020 (GLOBE NEWSWIRE) — BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) announced that the European Medicines Agency (EMA) has validated its marketing authorization application (MAA) submission for approval of oral, once-daily berotralstat (BCX7353) for the prevention of hereditary angioedema (HAE) attacks.
With this validation, the EMA has begun their formal review of the MAA under the centralized procedure for all member states of the European Union, and Norway, Iceland and Liechtenstein.An opinion from the Committee for Medicinal Products for Human Use (CHMP) is expected within approximately 12 months.“Berotralstat would represent the first targeted oral therapy approved for HAE prophylaxis in Europe and would deliver a major advance in therapy to HAE patients,” said Jon Stonehouse, chief executive officer of BioCryst.“HAE treatment in Europe tends to be consolidated and we have developed excellent relationships with HAE-treating physicians through our clinical trials. This is allowing us to build an efficient and experienced European commercial team to bring our innovative medicine to patients,” Stonehouse added.BioCryst expects three regulatory approvals for berotralstat in 2020 and early 2021. The U.S. Food and Drug Administration (FDA) is currently reviewing a new drug application for berotralstat and has set an action date of December 3, 2020 under the Prescription Drug User Fee Act (PDUFA). In Japan, the Pharmaceuticals and Medical Devices Agency (PMDA) is reviewing a new drug application (JNDA) for berotralstat under the Sakigake timeline, and the company expects Japanese approval in the second half of 2020.About BioCryst PharmaceuticalsBioCryst Pharmaceuticals discovers novel, oral small-molecule medicines that treat rare diseases in which significant unmet medical needs exist and an enzyme plays a key role in the biological pathway of the disease.
