Double-Blinded, Placebo-Controlled, Randomized, 2 Period, Crossover Phase 1/2a Study Testing Safety/Efficacy of Advair HFA (Salmeterol, Fluticasone) in Resting & Exercising Healthy & High Altitude Pulmonary Edema (HAPE) Predisposed Subjects
University of Colorado, Denver
Summary
The current protocol is composed of two studies. The first study is designed to carefully evaluate the safety of high-dose salmeterol/fluticasone (Advair HFA) versus placebo (hydrofluoroalkane, HFA) administration over 7 days, as well as the efficacy of the study drug to increase exercise performance, in healthy individuals exercising under hypoxic, simulated high-altitude conditions (Phase 1/2a study). The second study will examine sensitive measures of cardiopulmonary function using invasive cardiopulmonary testing, in both HAPE-sensitive and HAPE-resistant individuals, to assess the potential efficacy of salmeterol/fluticasone to prevent pulmonary edema and to enhance exercise capacity (Phase 2a) in these individuals.
Description
Both Study 1 and Study 2 are double-blinded, randomized, placebo-controlled, two-period, crossover studies. Study 1 (Phase 1/2a) is a Double-Blinded, Placebo-Controlled, Randomized, 2 Period, Crossover study examining safety and efficacy in healthy subjects dosed with salmeterol/fluticasone 126mcg/270mcg twice daily vs. placebo, for 7 days. Subjects will exercise under hypoxic conditions one time during each study period with the primary efficacy outcome being maximal oxygen uptake (VO2max), and secondary outcomes of arterial partial pressure of oxygen (PaO2), alveolar-arterial oxygen (Aa) gr…
