Active clinical trials for "Migraine Disorders"

Triptans are first choice drugs in the acute treatment of migraine and cluster headache. However, while in cluster headache the response rate to subcutaneous sumatriptan is 96%, around 30% of patients fail to respond to a particular triptan. Nonresponse is likely to be due to a variety of factors, including low and inconsistent absorption, inadequate dosing, and variability in individual response5. Timing of administration is also a crucial issue. In fact, an early treatment of the attack, when the pain is still mild, may increase the responders rate by circumventing the development of cutaneous allodynia (expression of central sensitization of pain pathway) during the course of the attack. Several studies have been performed in an attempt to genetically, psychologically and clinically characterize the triptan responders but failed to provide conclusive results. Nevertheless, we suggested that the presence of UAs during the migraine attack might predict a good response to triptans. UAs are common in migraine patients. They have been reported in almost one out of two migraineurs (45.8%) attending a tertiary headache centre and in more than one out of four (26.9%) in a population-based study. In an open study with sumatriptan 50 mg performed on 72 migraine patients with UAs, we described pain relief in 65.3% of the patients at 1 h and in 81.9% at 2 h, while pain-free in 30.6% at 1 h and in 61.1% at 2 h. We hypothesized a large-scale recruitment of peripheral neurovascular 5-HT1B/1D receptors consequent to the activation of the trigeminal-autonomic reflex in such patients. Our hypothesis has received further confirmation by the demonstration of higher levels of calcitonin gene-related peptide, neurokinin A and vasoactive intestinal peptide (the hallmark of the activation of the trigeminal autonomic reflex) in external jugular blood in rizatriptan responders than in non-responders. The investigators therefore postulate that migraineurs with UAs may respond better to rizatriptan than "general" migraine population. The aim of the study is to evaluate the efficacy of rizatriptan 10 mg lyophilized wafer (MLT) compared to placebo in the treatment of acute migraine in patients with unilateral autonomic symptoms (UAs: unilateral lacrimation, eye redness, eyelid oedema, nasal congestion or rhinorrhoea, miosis or ptosis, forehead or facial sweating) during the migraine attack.

This study was designed to determine how well the combination medication, sumatriptan and naproxen sodium, treats migraine headache in adolescents 12-17 years old

A study to assess safety and PK of an investigational drug in migraine patients during and between migraine attacks.

The purpose of this study is to determine whether a painless and noninvasive procedure called Transcranial Direct Current Stimulation (tDCS) can be an effective therapy for the treatment of migraine and migraine-associated pain. Stimulation of the motor cortex with tDCS has already been shown to relieve pain in patients with other chronic pain syndromes, including traumatic spinal cord injury and fibromyalgia. Patients with migraine are usually extremely sensitive to pain. A treatment that targets the areas of the brain that are related to the experience of pain may also help decrease pain in patients with migraine. Pain control with this localized approach may help avoid the problems due to pain medications that affect all organs in the body. We hypothesize that 10 sessions of Transcranial Direct Current Stimulation (tDCS) applied over the area of the brain that controls pain and motor function will decrease pain and headache frequency in patients with migraine.

A study to assess the safety, tolerability, and single dose pharmacokinetics of a marketed drug in pediatric subjects with migraines. After completion of a portion of the study (Panels A and B), a regulatory agency issued an amended request that the 12-17 year old age group studied should include a similar number of male and female subjects. Therefore, the study was amended to add an additional panel of subjects (Panel C) to ensure gender balance specifically in this age group.

The objective of this study was to evaluate the tolerability, safety, and pharmacokinetics of inhaled prochlorperazine

The primary objective is to compare the pharmacokinetics (PK) profiles among five NP101 patches in healthy volunteers. The secondary objective is to evaluate the safety of NP101 in healthy volunteers.

The purpose of this study is to evaluate the safety and effect of nasal carbon dioxide in the treatment of mild headaches in people who have migraines.

The general aim is to evaluate the relative oral bioavailability of BI 44370 TA tablets during and between migraine attacks as well as Safety, Tolerability and Pharmacokinetic

The purpose of this study is to determine the effectiveness of melatonin 3 mg compared to placebo and amitriptyline 25 mg in the preventive treatment of migraine.
