    Introduction:

    Physical deconditioning is common in patients with COPD, limiting exercise tolerance.

    Aim:

    PHYSACTO® (NCT02085161) tested the effects of bronchodilators alone or with exercise training (ExT), combined with a standardised physical activity self-management behaviour-modification (BM) programme, on exercise endurance time (EET) in patients with COPD.

    Methods:

    A 12-week (wk) randomised, partially double-blind, placebo (P)-controlled, parallel-group trial at 34 sites in Australia, New Zealand, USA, Canada and Europe. Interventions (all with 12-wk BM): P; tiotropium (T) 5 µg; T + olodaterol (T+O) 5/5 µg; T+O 5/5 µg with 8 wks' ExT (T+O 5/5 µg + ExT). EET (log transformed) during an endurance shuttle-walk test (ESWT) to symptom limitation was assessed after 8 wks (primary end point) and 12 wks.

    Results:

    303 patients (200 men) were randomised and treated (full analysis set n = 274). Mean post-bronchodilator FEV1 was 1.59 L (56.7% predicted). EET significantly increased with T+O 5/5 µg and T+O 5/5 µg + ExT versus P at 8 wks (Fig); 13 patients reached test termination criteria (20 mins) without symptom limitation (P, n = 0; T, n = 3; T+O, n = 2; T+O + ExT, n = 8) at 8 wks. No safety concerns were identified.

    Conclusions:

    T+O 5/5 µg, alone and combined with ExT, improved EET during ESWT compared to P in moderate to severe COPD.
