Oxygen/Therapeutic Use clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Correction of Exercise-induced Desaturation by Acute Oxygen Supply and Exercise Responses in COPD

RePox-1

Start date: February 2014
Phase: N/A
Study type: Observational

In the literature, the effects of acute oxygen administration on exercise tolerance and related symptoms have often appeared to be contradictory. Some investigations have reported benefits from acute oxygen supply during exertion, including increased exercise performance, reduced dyspnea, and better cardiorespiratory adaptations, whereas other studies have reported no improvement. Recently, we advanced then the hypothesis that some patients would be non-responders and even worsen under oxygen treatment. The preliminary results confirmed our hypothesis since we demonstrated that while 56% of the patients were improved with supplemental oxygen, 16% were non-responders and 28% were negative-responders (decreased performance and increased dyspnea during endurance exercise with supplemental oxygen). However, this was a pilot study offering preliminary insights and tentative conclusions that must be confirmed in a larger case series. The aims of this retrospective study was : 1. To confirm on cohorte and with clinical test (the 6-minute walking test - 6WT) the deleterious responses to acute oxygen supplementation in LTOT (long terme oxygenotherapy treatment) and non-LTOT patients who exhibit exercise desaturation. 2. To identify the predictive factors among the clinical data (i.e., anthropometric, spirometric and gazometric data) and/or functional data recorded during rehabilitation program
