Theravance has reported positive results from a third lung function trial comparing the efficacy and safety of Anoro Ellipta (umeclidinium /vilanterol, UMEC/VI) with the LAMA tiotropium, administered in the HandiHaler inhaler, in patients with chronic obstructive pulmonary disease (COPD).

Anoro Ellipta is a combination of long-acting muscarinic antagonist (LAMA) and long-acting beta2-adrenergic agonist (LABA).
The 24-week, blinded, parallel group, multicenter trial evaluated the efficacy and safety of UMEC/VI 62.5/25mcg inhalation powder administered once-daily in the dry powder inhaler, Ellipta, compared to tiotropium 18mcg administered once-daily in the HandiHaler inhaler.
The trial enrolled a total of 905 patients with COPD and they were randomized 1:1 to UMEC/VI 62.5/25mcg inhalation powder or tiotropium 18mcg.
At the end of the treatment period, UMEC/VI 62.5/25mcg showed a statistically significant improvement of 112mL compared with tiotropium 18mcg.
The most commonly reported side effects for both UMEC/VI and tiotropium included headache, nasopharyngitis, cough and back pain.
Theravance president and chief executive officer Michael Aguiar said: "We believe the results from this positive study will provide physicians with additional useful data regarding the potential benefits of Anoro Ellipta as a treatment option for appropriate patients with COPD."
