Randomized Controlled TrialPitolisant for Daytime Sleepiness in Obstructive Sleep Apnea Patients Refusing CPAP: A Randomized Trial.
Rationale: Excessive daytime sleepiness is a common disabling symptom in obstructive sleep apnea syndrome. Objectives: To evaluate the efficacy and safety of pitolisant, a selective histamine H3 receptor antagonist with wake-promoting effects, for the treatment of daytime sleepiness in patients with moderate to severe obstructive sleep apnea refusing continuous positive airway pressure treatment. Methods: In an international, multicenter, double-blind, randomized (3:1), placebo-controlled, parallel-design trial, pitolisant was individually titrated at up to 20 mg/d over 12 weeks. ⋯ Adverse event incidence, mainly headache, insomnia, nausea, and vertigo, was similar in the pitolisant and placebo groups (29.5% and 25.4%, respectively), with no cardiovascular or other significant safety concerns. Conclusions: Pitolisant significantly reduced self-reported daytime sleepiness and fatigue and improved patient-reported outcomes and physician disease severity assessment in sleepy patients with obstructive sleep apnea refusing or nonadherent to continuous positive airway pressure. Clinical trial registered with www.clinicaltrials.gov (NCT01072968) and EU Clinical Trials Register (EudraCT 2009-017251-94).

Randomized Controlled Trial Comparative StudyThrombomodulin alfa for Acute Exacerbation of Idiopathic Pulmonary Fibrosis: A Randomized, Double-blind, Placebo-controlled Trial.
Rationale: Acute exacerbation during the course of idiopathic pulmonary fibrosis causes a poor prognosis. Coagulation abnormalities and endothelial damage are involved in its pathogenesis. Thrombomodulin alfa, a recombinant human soluble thrombomodulin, has anticoagulant and antiinflammatory effects. ⋯ Conclusions: Thrombomodulin alfa did not improve the 90-day survival proportion. The present results suggest that the use of thrombomodulin alfa for the treatment of acute exacerbation of idiopathic pulmonary fibrosis not be recommended. Clinical trial registered with www.clinicaltrials.gov (NCT02739165).
