Sodium Oxybate in Patients With Episodic and Chronic Cluster Headache (SOinCH)

December 18, 2015 updated by: Ramin Khatami

Safety and Efficacy of Sodium Oxybate in the Prophylaxis of Headache and Sleep Disturbances in Patients With Chronic and Episodic Cluster Headache

The purpose of this study is to test the effects of sodium oxybate on headache response (frequency), sleep quality and quality of life in the prophylactic treatment of patients with chronic and episodic cluster headache. Oral sodium oxybate, 3-9g per night, starting with 3g in two nightly dosages of 1.5g and increased by steps of 1.5g every second or third night until treatment Response will be evaluated in an interventional, placebo-controlled, double-blind, randomised, parallel group, multicentre study. Primary outcome is reduction of nocturnal pain frequency Secondary outcomes are improvement of sleep quality at a subjective level as assessed by diary and standardized scales (PSQI, FOSQ), duration of pain free episodes, general clinical outcome (global evaluation), clinical global impression (CGI-S, CGI-I, CGI-E), quality of life (SF 36) and daytime sleepiness (Epworth Sleepiness Score).

Detailed Description

Multicenter study to test the safety and efficacy of sodium oxybate in the prophylaxis of headache and sleep disturbances in patients with chronic and episodic cluster headache using a placebo-controlled, double blind, randomized study, parallel group design. Patients with predominant nocturnal attacks and poor sleep quality will be evaluated; At least 1 attack every other day and at least 8 attacks cumulatively by the time prior to randomization are required. Sodium oxybate will be orally administered, 3-9g per night, starting with 3g in two nightly dosages of 1.5g (the first at bedtime and the second 4 hours later). Dosage will be gradually increased by steps of 1.5g every second night until treatment response during a titration period of 14 days. Effects od sodium oxybate will be monitored via pain and sleep diaries during a 14 days stable treatment phase by reviewing sleep/pain diaries and Quality of life assessement. Primary outcomes are frequency of nocturnal pain attacks; Main secondary outcomes are frequency, intensity and duration of daytime pain attacks, improvement of sleep quality, quality of life, duration and rates of pain free episodes, decrease in escape medication for acute headache attacks (use of triptans). Safety parameters are ECG, laboratory, depressions scales, vital signs, respiratory polygraphy. Intent-to treat analysis, multivariate analysis of variance (MANOVA) with depending variable (reduction of pain frequency and pain intensity of nocturnal attacks) and the co-variates (age, sex , chronic vs. episodic CH).

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
