The Food and Drug Administration (FDA) has approved the supplemental New Drug Application (sNDA) for Trelegy Ellipta (fluticasone furoate, umeclidinium, vilanterol; GlaxoSmithKline) for the maintenance treatment of asthma in patients aged 18 years and older.

Trelegy Ellipta combines fluticasone furoate, an inhaled corticosteroid with umeclidinium, an anticholinergic and vilanterol, a long-acting β2-adrenergic agonist (LABA). The approval was based on data from the double-blind, active-controlled phase 3 CAPTAIN study that evaluated the efficacy and safety of Trelegy Ellipta in 2436 adults with inadequately controlled asthma despite treatment with an inhaled corticosteroid (ICS)/LABA. Patients were randomized to 1 of the following groups and treatment was administered once daily:

  • Trelegy Ellipta 100/62.5/25mcg (n=406),
  • Trelegy Ellipta 200/62.5/25mcg (n=408),
  • Fluticasone furoate/umeclidinium/vilanterol 100/31.25/25mcg (n=405),
  • Fluticasone furoate/umeclidinium/vilanterol 200/31.25/25mcg (n=404)
  • Fluticasone furoate/vilanterol (FF/VI) 100/25mcg (n=407), or
  • Fluticasone furoate/vilanterol200/25mcg (n=406). 

The primary end point was the change from baseline in trough forced expiratory volume in 1 second (FEV1) at 24 weeks.

Results of the study showed a statistically significant 110mL improvement in trough FEV1 with Trelegy Ellipta 100/62.5/25mcg compared with FF/VI 100/25mcg (P <.001, 95% CI, 66-153mL). In addition, there was a statistically significant 92mL improvement in trough FEV1  with the Trelegy Ellipta 200/62.5/25mcg dose vs FF/VI 200/25mcg (P <.001, 95% CI, 49-135mL).
