Podcast # 353: Xofluza

Author: Sam Killian, MD

Educational Pearls:

  • Japan recently approved baloxavir marboxil (Xofluza), which may potentially “kill” Flu A/B within 24 hours
  • Recent RCT trial showed superiority over oseltamavir (Tamiflu) in cessation of viral shedding (24 vs 72 hours)
  • Compared to placebo, superior in time to symptom resolution (53.7 vs 80.7 ¬†hours)
  • Administered as single dose
  • Yet to be considered for FDA approval
