Brief Summary:
This is a double-blinded, randomized, parallel, placebo-controlled phase 2 study to evaluate the safety and efficacy of R-verapamil in the prophylaxis of episodic cluster headache.

Condition or disease Intervention/treatment Phase
Episodic Cluster Headache Drug: R-verapamil 75 mg tablet Drug: Placebo Phase 2

Detailed Description:
Approximately 30 subjects (about 15 per treatment group),will be enrolled and randomized to receive either R-verapamil or placebo for 2 weeks. The study will consist of a 1-week run-in period and a 2-week treatment period (R-verapamil or placebo). The total duration of the study for each treatment group is 3 weeks.
