Active clinical trials for "Migraine Disorders"

This study is being conducted to evaluate the efficacy of a 91-day extended cycle oral contraceptive compared to placebo for decreasing the frequency and severity of menstrually-related migraine headaches.

The circadian system with its centre in the hypothalamus is involved in migraine pathophysiology. Whether it plays a pivotal role is not clarified. The investigators postulate that a destabilized circadian system may increase migraine attack susceptibility, and that stabilization by supplying melatonin a migraine preventive effect will be achieved. A previous open label study has shown effects that certainly warrant a placebo controlled study.

The purpose of this study is to compare the reduction in the number of severe headache days at six months in people with chronic migraine treated with topiramate and propranolol versus those treated with topiramate and a placebo.

The primary objective of this study was to determine whether frovatriptan was effective in the prevention of menstrually associated migraine (MAM) headaches when compared to placebo. Secondary objectives included determining the effectiveness of frovatriptan in reducing the incidence, severity and duration of MAM headaches and associated symptoms, to evaluate the safety and tolerability of the two frovatriptan dosing regimens and to compare the effectiveness of these regimens in the prevention of MAM headaches. In this cross-over study, patients treated each of 3 perimenstrual periods (PMPs) with placebo, frovatriptan 2.5 mg daily (QD) and 2.5 mg twice daily (BID) for 6 days, starting 2 days before the anticipated onset of a MAM headache. A statistically significant reduction in the incidence of MAM headache (p<0.0001) was observed with both dosing regimens of frovatriptan when compared to placebo. Additionally, the frovatriptan BID regimen was superior to the frovatriptan QD regimen in the prevention of MAM headache (p<0.001). Significant reductions in MAM headache severity and duration, the incidence of associated symptoms and characteristics, and the use of rescue medication were observed when the PMP was treated with frovatriptan, compared to placebo. Both dose regimens of frovatriptan were equally well tolerated and no cardiovascular or other safety and tolerability concerns arose with repeated administration of frovatriptan over a 6 day period.

The purpose of this study is to evaluate the efficacy of botulinum toxin type A (Dysport®) injections into pericranial muscles compared to placebo to prevent migraine attacks.

The purpose of this study is to evaluate the efficacy and safety of Laxymig® ER compared with placebo in prophylactic monotherapy treatment of migraine headache.

The purpose of this study is to compare the effectiveness and safety of two treatment regimens in preventing migraines. The antidepressant amitriptyline has been used successfully to prevent migraine headaches.

The purpose of this study is to assess the safety and effectiveness of topiramate as compared to placebo for the prevention of headaches in patients with chronic migraine. Topiramate has been approved to prevent migraine headaches as well as in the treatment of epilepsy.

The purpose of this is study is to compare the efficacy of BHV-3000 (rimegepant) to placebo as a preventive treatment for migraine, as measured by the reduction in the number of migraine days per month.

To assess whether there is a sustained benefit and good safety with repeated onabotulinumtoxinA sessions in chronic migraine over more than three years of treatment. We prospectively enrolled 65 chronic migraine patients, who were classified as responders after three sessions of onabotulinumtoxin A and were eligible to further continue treatment.
