Alnylam Pharmaceuticals Inc. (NASDAQ:ALNY) announced that the European Commission has approved Givlaari (givosiran) for the treatment of acute hepatic porphyria (AHP) in patients aged 12 years or older. The drug will be available as subcutaneous injection. The approval in Europe was expected as the drug had received positive recommendation from the Committee for Medicinal Products for Human Use of the European Medicines Agency in January 2020.

The ultra-rare AHP disease can lead to severe abdominal pain, vomiting and seizures, which can be life-threatening due to the possibility of paralysis and respiratory arrest during attacks.

The approval was based on impressive data from the phase III ENVISION study, which showed that treatment with Givlaari resulted in 74% reduction in the rate of porphyria attacks. The drug is the first and only therapy approved in Europe, which demonstrated prevention of AHP attacks, reduction in chronic pain and improving quality of life.

Please note that Givlaari was approved by the FDA in November last year for the same indication. It has already been launched in the United States and generated $0.2 million in the fourth quarter of 2019. The drug is priced at $575,000 per annum in the U.S. market.

Shares of the company have rallied 31.1% year to date against the industry ’s decrease of 7.7%.
