Advair HFA in Healthy and HAPE Predisposed Subjects

United States60 participantsStarted 2023-12-12

Plain-language 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.

Inclusion Criteria: * Written informed consent signed prior to entry into the study. * Male or female age 18-50 years of age * BMI ≥ 20 and \< 35 kg/m2 * Agreement to comply with the study-required interventions and treatment during the full duration of the study. * In good health as determined by screening medical history, physical examination, vital signs (blood pressure, heart rate, respiratory rate and temperature), clinical laboratory tests (CBC, protime (PT) (INR)/partial thromboplastin time (PTT), thyroid stimulating hormone (TSH), Total Bilirubin, blood chemistries, urine drug screening), and a resting 12-lead Electrocardiogram with a 10 second rhythm strip. * Adequate peripheral venous access for IV insertion and blood sample collection (assessments will be made prior to undergoing further assessments). * HAPE-susceptible individuals (Study 2 only) must have had a medically documented (hospital admission or emergency room visit) HAPE episode characterized by noncardiogenic pulmonary edema and hypoxemia that occurred during high altitude travel in Colorado and must reside below 3,000 feet (unacclimatized individuals; non-Colorado residents). * HAPE-resistant individuals (Study 2 only) will have had no evidence of HAPE during high altitude travel in Colorado, and must reside below 3,000 feet (unacclimatized; often being travel partners of HAPE-susceptible subjects). * Healthy controls (Study 1 only) will all be Colorado residents.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
