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

Randomized, Double-Blind, Multi-Center, Parallel-Group Comparison of the Efficacy and Safety of the C213 (Zolmitriptan Microneedle System) to Placebo for the Acute Treatment of Cluster Headaches

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.

Study Overview

• Status: Completed
• Conditions: Cluster Headache
• Intervention / Treatment: Drug: C213 Microneedle System; Drug: Placebo

Detailed Description

This is a randomized, double-blinded, placebo-controlled study. Approximately 120 subjects who meet the entry criteria will be randomized 1:1:1 to 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].

Qualified subjects will randomize to the double-blind treatment period at Day 1 and will have up to 48 weeks to confirm and treat a cluster headache. Using the eDiary to confirm they are experiencing a cluster headache, subjects will self-administer the patches and continue to respond to questions in the eDiary until 1-hour post treatment administration.
