An Adaptive Design Trial Of GW274150 In The Treatment Of Acute Migraine

Phase 2

Completed

• Conditions: Migraine Disorders; Migraine

• Registration Number: NCT00319137
• Lead Sponsor: GlaxoSmithKline

Brief Summary

Nitric oxide (NO) is likely to be involved in the development of migraine headache. Nitric oxide synthase (NOS) is an important chemical involved in the production of NO. Reduction of NOS, and therefore NO, may be an effective technique for the treatment of migraine headache. GW274150 is a highly selective inhibitor of NOS and offers the potential of anti-inflammatory activity in migraine through a novel mechanism of action. The intent of this study is to investigate the safety and efficacy of GW274150 for the acute treatment of migraine headache.

• Typically have moderate to severe migraine pain preceded by an identifiable mild pain phase.
• No clinically significant abnormality identified on the medical or laboratory evaluation. A subject with a clinical abnormality or laboratory parameters outside the reference range may be included only if the doctor considers that the finding will not introduce additional risk factors and will not interfere with the study procedures.

• History of alcohol, substance or drug abuse within the last year.
• Taken a migraine prophylactic medication within 1 month of the Screening Visit.
• Uses an opiate as first line acute treatment for migraine attacks.
• History of ergotamine, triptan, opioid, or combination medication intake on greater than/equal 10 days per month on a regular basis for greater than/equal 3 months.
• History of simple analgesic intake on greater than/equal 15 days per month for greater than/equal 3 months.
• Do not receive migraine relief from a triptan migraine treatment.
• Uncontrolled hypertension at the Screening Visit, defined as systolic blood pressure >140mmHg or diastolic blood pressure >90mmHg.
