UPDATE – PharmaEssentia has corrected the press release issued 6 January about the Phase III results for Besremi in essential thrombocytopenia to note the incidence of two treatment-related serious adverse events in the Besremi arm; the previous press release reported zero TRSAEs. Scrip has revised this article to include the new data and confirmed the company’s view that Besremi has a relatively better safety profile than anagrelide.

Taiwan-headquartered PharmaEssentia is advancing toward its goal of adding a second indication – essential thrombocytopenia – to the label for Besremi, its pegylated interferon product approved in 2021 for polycythemia vera

Key Takeaways
  • PharmaEssentia reported successful Phase III data for Besremi in essential thrombocytopenia, a disease with no new drugs approved in the US since 1997.
  • Besremi is approved to treat polycythemia vera; adding ET to the product label would nearly double the product’s addressable patient population
