Active clinical trials for "Migraine Disorders"

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.

The Purpose of this study is to evaluate the impact of percutaneous closure of a patent foramen ovale (PFO) (a hole in the heart), using the AMPLATZER PFO Occluder, on the incidence of migraine headaches.

Migraine headaches are a common reason for patients to present to an emergency department. We are comparing two different medications to see which one is better for patients who present ot an emergency room with a migraine headache.

The purpose of this study is to evaluate the safety and efficacy of telcagepant in the treatment of acute migraine in participants with stable vascular disease. Acetaminophen/paracetamol (APAP) will be used as an active comparator in this study. The primary hypothesis of this study is that telcagepant 300 mg is superior to placebo.

The purpose of this study is to evaluate the safety and effectiveness (beyond 6 months) of individualized doses (100 to 200 milligrams) of topiramate for the prevention of migraine headaches over a period of 26 weeks.

The purpose of this study is to evaluate the safety and effectiveness of an implantable device for difficult to treat migraine. There are a significant number of patients who have drug refractory migraine and alternative therapies are needed.

The purpose of this study is to investigate the efficacy and safety of an MK 0974 for migraine headache and to identify an appropriate dose range for further study.

The purpose of this study is to evaluate the safety and efficacy of three doses of topiramate (50 milligrams[mg], 100mg, and 200mg taken daily) compared with placebo in the prevention of migraine.

The study drug levetiracetam is FDA approved as an add-on medication in the treatment of partial onset seizures in adults with epilepsy. The trade name is Keppra®. This is an "open-label" trial, which means that all participating patients will receive active study drug. The Jefferson Headache Center has developed this clinical study to evaluate the safety and effectiveness of levetiracetam in preventing migraine headaches, with or without aura (visual disturbances). In addition, the study site will be performing a procedure called Transcranial Magnetic Stimulation (TMS). This procedure measures brain activity because it is thought that people with migraine experience periods of cortical hyperexcitability or over-activity in the brain. This information may help physicians in the future determine which preventive medications will work for which patients.

The purpose of this study is to evaluate the impact of topiramate (migraine prevention medicine) on the effectiveness of almotriptan malate (acute migraine medicine) when treating acute migraine headaches.
