Episodic Cluster Headache | Sumatriptan 4 mg Statdose in the Acute Treatment of Cluster Headache

Episodic Cluster Headache research study

What is the primary objective of this study?

This study's hypothesis is the 4mg StatDose sumatriptan is effective for the acute treatment of cluster headache and provides good safety and tolerability across multiple doses of the study medication as well as across multiple attacks of cluster headache. This study seeks to determine the safety and efficacy of the commercially available 4mg StatDose formulation of sumatriptan as an acute treatment of cluster headache. Patients are allowed to use repeated dose of the study medication for a given headache if they have had a partial response to the first dose. They may treat up to 3 attacks of cluster headache with the study medication. Safety assessment will be through adverse event reporting and physical examination. Patients with both episodic cluster headache as well as chronic cluster headache will be studied. Patients must either not have started preventive treatment for cluster headache or be on a stable dose of preventive medication.

Exclusion Criteria: - Subject has confirmed or suspected ischemic heart disease, Prinzmetal's angina, or signs/symptoms consistent with any of the above. - Subject has cardiac arrhythmias requiring medication or a history of a clinically significant electrocardiogram abnormality that, in the investigator's opinion contraindicates participation in this study. - Subject has a history of congenital heart disease. - Subject has a history of cerebrovascular pathology including stroke. - The subject, in the investigator's opinion, is likely to have unrecognized cardiovascular disease. - Subject has evidence or history of ischemic abdominal syndromes or peripheral vascular disease. - Subject has uncontrolled hypertension at screening. - Subject has a history of epilepsy or structural brain lesions which lowers the convulsive threshold. - Subject has a history of impaired hepatic or renal function. - Subject is currently taking a monoamine oxidase inhibitor (MAO) or has taken a MAOI within the 2 weeks prior to screen - Subject is currently taking an ergotamine-containing or ergot-type cluster headache preventive medication like ergotamine tartrate or methylergonovine. - Subject has hypersensitivity or contraindication to the use of sumatriptan, any of its components, or any other 5-HT1B1D receptor agonist. - Subject is pregnant, actively trying to become pregnant or breast-feeding - Subject is of childbearing potential and not using adequate contraceptive measures. - Subject has evidence of alcohol or substance abuse within the last year which, in the investigator's judgment, will likely interfere with the study conduct, subject cooperation, or evaluation and interpretation of the study results. - Subject has any concurrent medical or psychiatric condition that, in the investigator's opinion, may affect the interpretation of efficacy and safety date or which otherwise contraindicates participation in a clinical trial. - Subject has participated in an investigational drug trial within the previous four weeks. - Subject is unable or unwilling to self administer subcutaneously administered Imitrex.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Sumatriptan 4mg Statdose injection4mg Sumatriptan Statdose injection for use as acute therapy in a cluster headache. Consistency of response in three attacks will be measured

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Study Status

Unknown status

Start Date: November 2006

Completed Date: August 2010

Phase: Phase 4

Type: Interventional


Primary Outcome: The primary efficacy parameters will be the percentage of cluster headache attacks that result in the cluster headache pain being reduced to mild or none following a single dose of 4 mg subcutaneous sumatriptan at 15 minutes and at 30 minutes.

Secondary Outcome: The time meaningful relief of cluster headache.
