Pitolisant (BF2.649) in the Treatment of EDS in Patients With OSA
- Conditions
- Excessive Daytime SleepinessObstructive Sleep Apnea
- Interventions
- Drug: Placebo
- Registration Number
- NCT02739568
- Lead Sponsor
- Bioprojet
- Brief Summary
The first objective of this study is to demonstrate the efficacy and safety of pitolisant given at 10, 20, or 40 mg per day versus placebo during 12 weeks of the Double Blind period, to treat the Excessive Daytime Sleepiness (EDS) in patients with Obstructive Sleep Apnea (OSA) refusing the nasal Continuous Positive Airway Pressure (nCPAP) therapy or treated by nCPAP but still complaining of EDS.
The secondary objectives of the study include assessing the long-term tolerance as well as the maintenance of efficacy of pitolisant given at 10, 20 or 40 mg per day during 39 weeks of Open Label Extension period and further investigating the co-variates or co-medications that affect the pharmacokinetics of pitolisant in the target population.

- Polysomnography performed (for patients submitted to nCPAP therapy - under nCPAP) between V1 and V2 or during the last 12 months with Apnea-Hypopnea Index (AHI): for patients without nCPAP therapy ≥ 15; for patients under nCPAP therapy less or equal to 10
- For patients submitted to nCPAP therapy: nCPAP ≥ 4 hours / day (compliance checked on the clock-time counter of the CPAP machine)

- If specified by the investigator, the patient must be willing not to operate a car (if sleepy at wheel) or heavy machinery for the duration of the trial or as long as the investigator deems it clinically indicated. In addition, the patient should be willing to maintain during the study their usual behaviors which could affect their diurnal sleepiness (e.g. circadian rhythm, caffeine consumption, nocturnal sleep duration)
