Active clinical trials for "Migraine without Aura"

Primary objective: To investigate the efficacy and tolerability of two doses of tonabersat compared to placebo in the prophylaxis of migraine headache and to evaluate the longer term tolerability of tonabersat in an open label extension. Secondary objective(s): To obtain further data on the efficacy and dose response of tonabersat; To extend the safety and tolerability database of tonabersat; To obtain data on the pharmacokinetics of tonabersat.

Overall trial objectives: Can treatment with tonabersat reduce the number of days with a migraine headache in patients who suffer from frequent migraine attacks How well tolerated is treatment with tonabersat The study is based on the hypothesis that the unique mechanism of action of tonabersat will inhibit some of the early events in the generation of migraine and so be effective as prophylactic treatment

This study aims to detect changes in RNFL thickness in patients with different types of migraine in comparison to healthy control. This will be accomplished by comparing the optic nerve head (ONH) parameters, RNFL thickness, and ocular perfusion pressure (OPP) in migraine patients with age and sex matched healthy control.

Amylin and calcitonin gene related peptide (CGRP) are related to the same peptide family. Both share 16 out of 37 amino acids and can activate each others receptor. CGRP is implicated in migraine pathophysiology but the role of Amylin and its receptor in migraine is not fully clarified.

The purpose of this study is to examine and compare the effect of pituitary adenylate cyclase-activating polypeptide-38 (PACAP38) and vasoactive intestinal polypeptide (VIP) on intracranial arteries and neuronal activity in patients with migraine without aura using a high resolution magnetic resonance imaging (MRI), including MR angiography (MRA) and functional MRI (fMRI). MRA will be used to detect changes in intracranial artery circumferences before and after PACAP38 and VIP. fMRI will be used oo detect changes in blood-oxygenation-level-dependent-signal (BOLD-signal). PACAP38 but not VIP induces migraine like attacks in migraine patients. The migraine specific drug sumatriptan will be given to relieve pain and the effect will also be registered using MRA and fMRI.

The investigators hypothesized that migraine without patients with many genetic loci associated with migraine (high genetic load) would be more sensitive and get provoked more migraine attacks by calcitonin gene-related peptide (CGRP) compared to patients with few genetic loci associated with migraine (low genetic load).

This study recruits 30 subjects into three groups, including two experimental groups and one control group. The two experimental groups receive acupuncture treatment for 4 weeks and two times functional magnetic resonance imaging scans as well as clinical symptom assessments. The control group receive one scan without any intervention. The aim of this study is to find the whether the effect of acupuncture treatment have diversity among migraineurs with different disease course.

The purpose of the study is assessment of the safety and efficacy of the De-Novo therapy in the treatment of craniofacial neuralgia and migraine headaches.This is an open-label study of simultaneous administration of combination of dexamethasone, lidocaine, and thiamine into the trigeminal nerve branches as well as greater and lesser occipital nerve bilaterally in one session. Patients who meet the exclusion and inclusion criteria are eligible for trial if they have experienced chronic migraine and craniofacial pain not responding to other prior therapies.

The aim is to compare the effectiveness of a behavioral treatment, the Acceptance and Commitment Therapy, provided as an add-on to the prophylactic treatment (treatment as usual-TaU) against TaU only on the reduction of monthly headaches frequency over 12 months in a sample of patients with high-frequency migraine without aura (i.e. reporting 9-14 days with headache per month in the previous three months). ACT will be provided in small groups (5-7 patients each) by specifically trained therapists. The ACT consists in 6 weekly sessions, 90 minutes each, and 2 supplementary "booster" sessions, at two and four weeks after the conclusion of the weekly session. The main focus of the six ACT session will be the following: 1) Creative helplessness: the problem of control; 2) Identifying values: introduction to Mindfulness; 3) Actions guided by values: working with thought; 4) Working with Acceptance and Willingness; 5) Committed Actions: self-as-context; 6) Integration: working with obstacles - wrap-up. The booster session starts with a mindfulness exercise, followed by a review of the contents covered across the ACT program. TaU will consist of education of patients, followed by pharmacological prophylaxis. Prophylaxis is prescribed based on patients' profile, such as previous failures, contraindications and so on by a neurologist with expertise in headache treatments and limited to Topiramate, Propanolol, Amytriptiline or Calcium channel blockers. The study will be a Phase II Trial; randomized, Open-Label; Multicenter study. Patients will be randomized 1:1 to the two groups: 64 patients (32 per group) will be enrolled to detect an absolute difference of at least 2 migraine days/month in the experimental group (assuming alfa 5%, power 95%, up to 15% loss to follow-up).
