Filter by:The primary objective is to evaluate the safety of long-term treatment with NP101 as assessed by: - Subject self-examination skin irritation scores - Adverse events - Changes in vital signs and ECG parameters The secondary objective is to evaluate the long term efficacy of NP101 as assessed by: - Headache pain free at two hours after patch activation for all initial acute migraine attacks treated with NP101 - Headache pain relief at two hours after patch activation for all initial acute migraine attacks treated with NP101 - Nausea free at two hours after patch activation for all initial acute migraine attacks treated with NP101 - Phonophobia free at two hours after patch activation for all initial acute migraine attacks treated with NP101 - Photophobia free at two hours after patch activation for all initial acute migraine attacks treated with NP101 - Migraine free at two hours after patch activation for all initial acute migraine attacks treated with NP101 This study will use an open-label design to assess the long term safety of NP101 (sumatriptan iontophoretic transdermal patch). Subjects who continue to be in good health (use of a triptan or use of an NP101 patch is not contraindicated) and received treatment (patch activation) with the study patch for a qualifying migraine under study NP101-007 will be considered eligible for enrollment into the open-label study. Subjects will be expected to remain in the study for up to 12 months.
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.
To assess CGRP levels in saliva through the evolution of migraine.
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.
This study will test the safety and how effective telcagepant is when taken with ibuprofen or acetaminophen in participants with migraine with or without aura. The primary study hypothesis is that at least one drug combination is superior to telecagepant alone in the treatment of acute migraines.
What is the course of migraine headache recurrence, how is it managed, what characteristics are associated with it, and how does it influence patient satisfaction with treatment?
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.
The objective of this trial is to assess the safety, tolerability, and efficacy of three doses of BI 44370 TA in the treatment of patients with an acute migraine attack and headache pain of moderate or severe intensity, compared to placebo and an active comparator.
This study will be the first to provide data about the relationship between PFO and migraine in children. By establishing the actual prevalence, we will better understand if PFO plays a role in the occurence of pediatric migraine and, thus, provide the incentive to perform additional studies evaluating whether PFO closure is an effective treatment option for pediatric migraine. For children with migraine headaches, discovering novel and effective treatments would be life altering.
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
