Baloxavir Marboxil Shows Promise in 2 Phase 3 Studies

In October 2018, the FDA approved baloxavir marboxil (Xofluza) for the treatment of acute, uncomplicated influenza in people 12 years of age and older. The approval marked the first new antiviral flu treatment with a novel mechanism in nearly 2 decades.

On September 1, 2019, at the OPTIONS X Congress in Singapore, investigators from Genentech announced favorable results from 2 phase 3 trials of baloxavir marboxil, MINISTONE-2 and BLOCKSTONE, in a late-breaking session.

MINISTONE-2

The MINISTONE-2 study was a phase 3 trial that evaluated the pharmacokinetics and efficacy of 1 dose of baloxavir marboxil compared with oseltamivir in children <1 year to 12 years of age.

BLOCKSTONE

The phase 3 BLOCKSTONE trial was a randomized, post-exposure prophylaxis study that evaluated a single dose of baloxavir marboxil compared with placebo as a preventive treatment for individuals living with someone with an influenza infection confirmed by a rapid influenza diagnostic test.
