NCT02637648
First received: December 9, 2015
Last updated: December 18, 2015
Last verified: December 2015
  Purpose
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

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Current diagnosis of cluster headache according to the criteria of International Headache Classification (ICHD-II, 2005) of the International Headache Society (IHS).
  2. Diagnosis of cluster headache has been made at least 6 weeks after start of screening
  3. Patients will have nocturnal pain attacks
  4. Duration since onset of current cluster episode at least 1 week
  5. Patients will have at least 1 attack per 48 hours and at least 4 attacks cumulatively by the time of visit 2 (prior to randomization)
  6. Disturbed sleep quality
  7. Patients have expressed a willingness to participate in and complete the study, and signed and dated informed consent prior to beginning protocol required procedures.
  8. Women must be surgically sterile or 2 years postmenopausal. Females of child-bearing potential must use a medically accepted effective method of birth control. Patients should agree to continue this method for the duration of the study and for one month after the discontinuation of SO treatment. Women should be negative to serum pregnancy test performed at the screening visit. Females should not be breastfeeding patient.
  9. In the opinion of the investigator, the patient must have adequate support to comply with the entire study requirements as described in the protocol (e.g., transportation to and from trial site, self rating scales and diaries completion, drug compliance, scheduled visits, tests).
  10. If indicated by investigator, patient must be willing to not operate a car or heavy machinery for 6 hours after the last intake of the investigational drug during the duration of the trial or as long as the investigator deems clinically indicated. In addition, the patient should be willing to abstain during the study any alcohol consumption or behaviours which could interact with the investigational drug.

  12. Patients having a severe renal impairment (e.g. serum creatine greater than 2.0 mg/dl), or a with severe hepatic impairment (abnormal liver function tests SGOT [AST] or SGPT [ALT] more than twice of the upper limit of normal) or elevated serum bilirubin (more than 1.5 times the upper limit of normal) or receiving anti-vitamin K substances.
