DyspneaEarly Phase 1NCT01851993
Inhaled Ondansetron & Dyspnea
A Early Phase 1 study testing Ondansetron in people with Dyspnea, run by McGill University at 1 site in Canada.
Trial summary
"Dyspnea" refers to the awareness of breathing discomfort that is typically experienced during exercise in health and disease. In various participant populations, dyspnea is a predictor of disability and death; and contributes to exercise intolerance and an adverse health-related quality-of-life. Read more about this study

About this study
Official title: Effects of Inhaled Ondansetron on Perceived Respiratory Discomfort (Dyspnea) During Exercise in the Presence of External Thoracic Restriction
"Dyspnea" refers to the awareness of breathing discomfort that is typically experienced during exercise in health and disease. In various participant populations, dyspnea is a predictor of disability and death; and contributes to exercise intolerance and an adverse health-related quality-of-life. It follows that alleviating dyspnea and improving exercise tolerance are among the principal goals of disease management. Nevertheless, the effective management of dyspnea and activity-limitation remains an elusive goal for many healthcare providers and current strategies aimed at reversing the underlying chronic disease are only partially successful in this regard. Thus, research aimed at identifying dyspnea-specific medications to complement existing therapies for the management of exertional symptoms is timely and clinically relevant. The purpose of this study is to test the hypothesis that single-dose inhalation of nebulized ondansetron (a serotonin 5-HT3 receptor antagonist) will improve the perception of dyspnea during strenuous exercise in health, young men. To this end, the investigators will compare the effects of inhaled 0.9% saline placebo and inhaled ondansetron (8 mg) on detailed assessments of neural respiratory drive (diaphragm EMG), ventilation, breathing pattern, dynamic operating lung volumes, contractile respiratory muscle function, cardio-metabolic function and dyspnea (sensory intensity and affective responses) during symptom-limited, high-intensity, constant-work-rate cycle exercise testing in healthy, men aged 20-40 years.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Ondansetron in people with Dyspnea, run by McGill University at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sensory Intensity (Borg 0-10 scale) ratings of dyspnea at isotime (time frame: Participants will be followed until all study visits are complete, an expected average of 3 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2015.
