Active clinical trials for "Migraine Disorders"

This study will evaluate the effectiveness and benefit of treatment with onabotulinumtoxinA in Chronic Migraine patients who have received a minimum of 7 treatment cycles.

Anti-migraine drugs, including triptans, are not indicated for use in pregnancy. However, the peak prevalence of migraine is in women of childbearing age. This, coupled with the sporadic nature of migraine attacks and high rates of unplanned pregnancies, makes unintentional exposure to anti-migraine medications during pregnancy likely. Prior to an anti-migraine medication being marketed there are few data available on drug safety in pregnancy: data from animal models may not translate directly to humans and pregnant women are routinely excluded from clinical trials. The Sumatriptan Pregnancy Registry was established by GlaxoSmithKline (GSK) in 1996 to monitor the safety of sumatriptan during pregnancy. It was combined with the Naratriptan Pregnancy Registry in 2001 and data collection on the sumatriptan-naproxen combination (Treximet) began in 2008.

Intraject is a needle-free, single use, disposable, subcutaneous delivery system pre-filled with 6mg Sumatriptan to be used by patients to treat acute migraine treatment. Study participation will last one month and include 2 doctor visits and 2-4 phone calls.

The purpose of the study is to compare the rate of comorbidities associated with migraine aura (MA) between persons who have a large circulatory right-to-left shunt (RLS) and those who do not have RLS. Approximately 50% of individuals who have MA also have RLS due to patent foramen ovale (PFO). A PFO is an anatomical opening or flap between the upper chambers of the heart or atria that permits blood to pass from the right of the heart to the left side of the heart, without first going to the lungs to be filtered and oxygenated. Many health conditions and clinical syndromes including stroke, sleep apnea, and migraine have been linked to PFO. Although the mechanism is undetermined, it is hypothesized that microscopic blood clots and chemicals such as serotonin can pass through the PFO, travel to the brain, and cause headache and aura. Persons who have MA are at increased risk for stroke and transient ischemic attacks relative to people who do not have migraine. Migraine is also associated with the presence of white matter lesions in the brain and mild deficits in cognitive function associated with the posterior brain (vision, memory, processing speed). The risk of stroke in migraine is highest for women under the age of 45 who have aura and a high number of migraine headache days per month. No convincing evidence has been produced to explain the mechanism for the increased risk of ischemic stroke in migraine; however, increased platelet activation and aggregation is a plausible theory. We hypothesize that migraineurs with aura and large RLS (presumably due to a PFO) will be more likely to have sleep apnea, increased platelet activation, cognitive deficits, alterations in cerebral vasomotor function, and white matter lesions than migraineurs with aura who do not have PFO. The results of this exploratory study will generate hypotheses as to why subgroups of migraineurs have an increased risk of stroke and the impact of large PFO on comorbid conditions associated with migraine aura. Early identification of migraine subgroups with a constellation of clinical syndromes that increase risk of neurovascular diseases will allow initiation of preventive strategies that may ultimately reduce burden and improve the productive quality of life for these individuals.

The study is designed to investigate the information on safety and efficacy of naratriptan tablets on Japanese subjects with migraine headache during Japanese post-marketing surveillance period.

To investigate the long-term safety and efficacy of AMERGE (naratriptan hydrochloride) on Japanese patients with migraine headache in clinical setting

The purpose of this study is to determine the central 5-HT1B receptor occupancy of ZOMIG® Rapimelt (zolmitriptan) in healthy male volunteers.

AM is a naturally occurring peptide in the body and consists of 52 amino acids. AM belongs to the calcitonin gene-related peptide (CGRP) superfamily and has several structural, physiological and pharmacological similarities to CGRP, intermdine and amylin. In a randomized double-blind, placebo controlled cross-over design 20 migraine patients without aura recruited to receive infusion of adrenomedullin or placebo (saline).

Treatment of chronic migraineurs who have failed more than 3 preventive drugs with Erenumab alone, to reduce frequency of monthly migraine days or as an add on therapy

This study aims to investigate the effect of erenumab on efficacy outcomes, tolerability outcomes, and patient-reported outcomes in individuals with migraine. Furthermore, the study aims to identify clinical predictors of erenumab response.
