FDA Delays Approval of Brilinta (Ticagrelor) 1

Updated, Friday December 17, 1 PM– Despite widespread expectations of an easy approval, the FDA has issued a complete response letter to AstraZeneca for Brilinta (ticagrelor). According to a press release from the company, the FDA has asked for additional analyses of the PLATO data, but did not request any additional studies. AstraZeneca said it is evaluating the letter and will respond to the FDA as soon as possible. The company said it remains confident that the drug will eventually gain approval.

Revising an earlier estimate based on the initial press release, a Leerink Swann analyst said on Friday that the company had “a very high degree of confidence in a rapid response to FDA’s request for add’l data analyses for the Brilinta NDA.” Seamus Fernandez said the company would respond to the FDA in January and predicted approval in 6-9 months. Although details are not yet available, a major concern of the FDA is likely to involve the lack of efficacy of ticagrelor in the pivotal PLATO trial in patients treated in the US.
