ObjectivesThe primary objective was to evaluate the effects of pregabalin relative to placebo in patients with chronic unilateral cervicogenic headache. Primary and secondary end points: To assess the change from baseline in the frequency of cervicogenic headache days per 28-day period between placebo and treatment group. To assess the change from baseline in the intensity of headache, and health outcome measures.Study DesignThis was a double-blind, randomized, placebo-controlled, parallel-group study, evaluating the efficacy and safety of pregabalin in patients with cervicogenic headache.ProceduresThe study consisted of two phases. A baseline of -28 days and a double-blind placebo-controlled phase: with an escalation and maintenance phase, during which patients remained at their highest dose until the end of the study, at Day 86.ResultsForty one patients were randomized, predominantly females, with a mean age of 52 years old. At screening, both groups had, on average, 26 headache-days per month. By the final phase of the study, the number of headache days dropped to 16 per month for the pregabalin group while remaining stable for the placebo group (p=0.037). No serious adverse events were reported during the study.ConclusionIn this study, primary objectives were achieved with a statistically significant change of ten days in frequency of headache days; with minor side effects that were well tolerated.
