GlaxoSmithKline's Scores FDA Approval For First IL-5 Inhibitor In Nasal Polyps

  • The FDA approved GlaxoSmithKline Plc's GSK Nucala (mepolizumab) for chronic rhinosinusitis with nasal polyps, making it the first IL-5 inhibitor to break into the indication.
  • The approval comes as an add-on maintenance therapy for adults with inadequate response to nasal corticosteroids.
  • The approval marks Nucala's fourth in eosinophilic-driven diseases.
  • The FDA based its approval on results from the phase 3 SYNAPSE study, which pitted Nucala against placebo in more than 400 patients.
  • In the 52-week trial, 57% fewer patients on Nucala needed surgery versus those in the placebo arm, GSK noted. Fewer patients on Nucala needed systemic corticosteroids, too. 
  • The drug also cut the size of nasal polyps and nasal obstruction over the 52 weeks.
  • Price Action: GSK shares are down 0.5% at $39.92 during the market session on the last check Friday.
