Participant gender:
All
Summary
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.

1. At least 1 cluster period

2. Averaging 2-6 headaches per day

3. Lasting at least 7 days

tension-type headaches)

6. Women of child-bearing potential must not be pregnant, must agree to avoid pregnancy
during the trial, and must use one of the following or be surgically sterilized:

5. Previous M207/C213 exposure in a clinical trial

6. Subject has other significant pain problems that might confound the study assessments
in the opinion of the investigator

7. Diagnosis of any malignant disease (other than adequately treated or excised
non-metastatic basal cell carcinoma or squamous cell carcinoma of the skin) within the
5 years prior to screening

8. History of unstable psychiatric illness requiring medication or hospitalization in the

Aspartate Aminotransferase (AST) > 130 U/L or bilirubin > 2x ULN]

14. Clinically significant kidney disease (eGFR < 60 ml/min / 1.73 m² or to creatinine >
1.5 x ULN)

15. Subject has clinically significant ECG findings, defined by:

1. ischemic changes (defined as > 1mm of down-sloping ST segment depression in at
least two contiguous leads)

2. Q-waves in at least two contiguous leads

3. clinically significant intra-ventricular conduction abnormalities (left bundle
branch block or Wolf-Parkinson-White syndrome)

4. clinically significant arrhythmias (e.g., current atrial fibrillation)

16. History of coronary artery disease (CAD), coronary vasospasm (including Prinzmetal's
