Active clinical trials for "Migraine Disorders"

The purpose of this study is to determine the prevalence of migraine in infertile women and during in Vitro Fertilization protocol. Migraine is two to three times as common in women as in men. Migraine has considerable impact on quality of life. In Vitro Fertilization has become a common therapeutic modality in modern fertility medicines. Treatment protocols are associated with exaggerated hormonal fluctuations. Estrogen is considered to be closely linked to migraine and its fluctuations have been considered to trigger migrainous headaches.

This is a multi-center registry that will prospectively collect regulatory compliant data from children and adolescents with migraine. This study will enroll approximately 200 participants from approximately 20 sites and will examine migraine symptoms, therapeutics used, and biomarkers associated with migraine.

The main aim of the present pilot study is to prove the possibility to use the Nitroglycerin (NTG) model to describe the pathophysiology of headache using task-free advanced Magnetic Resonance Imaging (MRI) techniques, in order to depict the static changes of the ictal and inter-ictal phase of migraine attacks vs the pain free state in healthy subjects and to compare that with the spontaneous headache attack experienced by chronic migraineurs.

The goal of this study is to measure medical resource utilization, treatment patterns, and costs for 1.) triptan-naïve patients with new pharmacy claims for a combination treatment of sumatriptan and naproxen sodium (SumaRT/Nap) or single-entity triptan and 2.) patients who are switched from one triptan to either SumaRT/Nap or a different single-entity triptan. The analysis will compare the mean number of prescription tablets used (including triptans, NSAIDs, opioids, and ergots) and migraine-specific medical resource utilization/costs and pharmacy costs incurred by health plan members who switched to SumaRT/Nap from a single-entity triptan. The null hypothesis for the triptan-naïve analysis is that no difference will be observed between resource utilization and costs incurred by patients treated with SumaRT/Nap and those treated with a single-entity triptan. The test hypothesis is that one group will incur significantly fewer costs and/or significantly lower health care utilization. For the triptan switch analysis, the null hypothesis is that no difference will be observed in the costs or health care utilization between triptan patients who are switched to SumaRT/Nap compared with those switched to a new triptan. The test hypothesis is that one treatment group will experience significantly lower costs and/or lower health care utilization. The source of data for this analysis is the Lifelink Health Plan Claims Database (owned by IMS Health, Inc). This claims database includes more than 60 million covered lives. In addition to inpatient and outpatient records, this database includes standard and mail-order pharmacy claims with paid and charged amounts and dates of service. Data from July 1, 2008 to December 31, 2009 (study period) will be used to conduct these retrospective analyses. Patients with at least one pharmacy claim for SumaRT/Nap between January 1, 2009 and June 30, 2009 (enrollment period) will be identified. The date of the first SumaRT/Nap pharmacy claim will be the index date for those patients. Each patient will be propensity score matched with an oral triptan patient based on the following pre-index covariates: age; gender; payer; geographic region; average monthly number of tablets of triptans, NSAIDs, and opioids; and average number of hospitalizations, emergency department visits, and physician visits in the month immediately preceding the index date as well as the mean number of hospitalizations, emergency department visits, and physician visits in the 5-month pre-index period. SumaRT/Nap patients and their single-entity matched controls who had no pharmacy claims for triptans prior to the index date will be analyzed in the triptan naïve group, and the SumaRT/Nap patients and their single-entity matched controls who switched to a new triptan will be analyzed in the switch analysis.

The purpose of this study is to determine whether there is an association between migraine in children and certain patterns of appetite or eating behaviour that may lead to later obesity.

This is a 2 visit research study for patients with or without a diagnosis of migraine. Participants will be administered informed consent, have a medical history taken and a physical examination performed, and complete 3 questionnaires at the first visit. The participants will have a functional MRI performed after completion of Visit 1. Study stipends will be given for each completed research visit. The purpose of this study is to potentially identify risk factors and/or biomarkers (which are differences in the brain structures)by comparing the brain MRI scans of migraine sufferers to brain scans of control persons to attempt to identify migraine progression using the functional MRI scans.

The purpose of this study is to determine if there are genetic variations that can explain a genetic basis for cyclic vomiting syndrome (CVS).

Migraine was described as related to stroke in adults and children as well. Complete thrombophilic status was not study in large groups of pediatric patients. The purpose of our study is to assess the prethrombotic profile among children and teenagers diagnosed as suffering from migraine attacks.

Transformed migraine is the most common and challenging subtype of chronic daily headache disorders35. Patients with transformed migraine often report an evolutionary process that occurs over months or years in which headaches increase in frequency, change characteristics and ultimately result in patterns of daily or near-daily headaches resembling a mixture of tension-type headache and migraine.

The proposed study is a retrospective, non-interventional analysis that uses medical and pharmacy claims data in the US from Komodo Health
