Efficacy of Albuterol SPIROMAX® in Adult and Adolescent Patients With Exercise-Induced Bronchoconstriction (EIB)

A Single-Dose Study to Assess the Efficacy of Albuterol SPIROMAX® in Adult and Adolescent Patients With Exercise-Induced Bronchoconstriction (EIB)

The primary objective of this study is to evaluate the efficacy of a single dose (2 inhalations, 180 mcg total) of Albuterol SPIROMAX (90 mcg per inhalation) versus placebo in patients with EIB.

This study is a single-dose, randomized, double-blind, placebo-controlled, 2-treatment, 2-sequence, 2-way crossover, multicenter study in patients with a documented history of EIB, with or without underlying asthma. Each patient will participate in the study for approximately 5 weeks. Each patient will complete 2 screening visits (SV1 and SV2), 2 treatment visits (TV1 and TV2), and a follow-up telephone call (FV).
