Double-Blind Comparison of the Efficacy and Safety of C213 to Placebo for the Acute Treatment of Cluster Headaches

Completed · Phase 2/Phase 3 · Has a placebo group

Conditions studied: Cluster Headache

In brief

This is a double-blind, placebo-controlled study. Subjects who meet the entry criteria will be randomized o receive one of three blinded treatments \[C213 1.9 mg patch and placebo patch; C213 3.8 mg (1.9 mg x 2 patches), two placebo patches\] on Day 1 and will have up to 48 weeks to confirm and treat a cluster headache. Subjects will self-administer the patches and respond to questions in the electronic diary (eDiary) until 1-hour post treatment administration.
