Pitolisant Reduces Daytime Sleepiness in Patients Nonadherent to CPAP

In patients with obstructive sleep apnea (OSA) who refuse or are nonadherent to continuous positive airway pressure (CPAP) therapy, treatment with pitolisant may reduce self-reported excessive daytime sleepiness, according to study results published in the American Journal of Respiratory and Critical Care Medicine.

Researchers conducted a phase 3, prospective, double-blind, randomized, placebo-controlled, parallel-design clinical trial (ClinicalTrials.gov Identifier: NCT01072968) in 28 hospital sleep clinics in 10 European countries between October 6, 2011, and May 7, 2014. The investigators sought to assess the efficacy and safety of the selective histamine

H3-receptor antagonist pitolisant during a 12-week period  for the treatment of daytime sleepiness in patients with moderate to severe OSA (defined as  apnea-hypopnea index ≥15/h with an Epworth Sleepiness Scale [ESS] score of ≥12) without significant cardiovascular disease. All of the patients either refused or were not adherent to CPAP therapy.

Results of the study demonstrated that ESS scores were significantly reduced among patients in the pitolisant group compared with placebo (-2.8 reduction in ESS with pitolisant; 95% CI, -4.0 to -1.5; <.001). Wake maintenance tests, however, were not improved with pitolisant. In addition, treatment with pitolisant was associated with reductions in Pichot Fatigue scores, with a significant mean change between groups (-3.6±5.6 vs -1.0±6.3; P =.005). Both patients’ and physicians’ questionnaires confirmed the overall effect of treatment with pitolisant.
