Active clinical trials for "Migraine Disorders"

A pharmacokinetic drug interaction study of erenumab and an oral contraceptive containing progestin and estrogen.

This will be a double-blind, randomised, placebo-controlled, two period cross over study of ibudilast in the treatment of chronic migraine. For participants resident in Adelaide, South Australia (i.e. "local participants"): The study will involve a screening visit followed by eight visits to the Pain and Anaesthesia Research Clinic (PARC), within the Royal Adelaide Hospital (RAH), for baseline testing, initiation of the study medications and ongoing data collection (one baseline and three study visits during each treatment period). At the baseline visit, blood samples to assess biomarkers (glutamate, calcitonin gene-related peptide, glial fibrillary acidic protein and S100β) will be taken. Patients will then be randomised (in a 1:1 ratio) to commence either ibudilast or placebo treatment, which will continue for 8 weeks. Subsequently participants will undergo a 4-week washout period. At the end of the washout period a second 8-week treatment block with the alternative treatment will commence. Patients will complete a headache diary daily for at least 4 weeks prior to the baseline visit, throughout the treatment and washout periods and for 4 weeks after treatment ceases. The diary will record headache frequency, duration, intensity, pain characteristics and medication intake for comparison with baseline data. From screening until the final study visit (over a minimum of 6 months) a total of approximately 200 mL in blood samples will be taken from each local participant. For participants located in country or interstate locations: The same study will be undertaken, but instead of attending the Pain and Anaesthesia Research Clinic (PARC), within the Royal Adelaide Hospital (RAH) for screening and study visits, these will be managed remotely through: basic input from the participant's GP during the screening period correspondence with the PI and study staff via registered post, phone or Skype scheduled visits to the nearest pathology collection centre for blood biochemistry and haematology analysis Interstate or country participants will also be exempt from collection of blood samples for biomarker analysis, hence a total of approximately 120 mL of blood samples will be taken from each interstate or country participant.

The purpose of the study is to assess whether, in individuals with migraines, a low-fat, vegan diet improves pain more effectively than a control supplement or a placebo. The principal measures are pain as measured by Visual Analog Scale (VAS) and the change in migraines frequency. The study duration is 36 weeks.This study also tests that a low fat, plant-based (vegan) diet free of foods commonly identified as triggers improves mood, using the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), and the Beck Depression Inventory II (BDI-II).

A major reason for the substantial underuse of pharmacological prevention of migraine is its inadequate efficacy, since only ~50% of patients respond to a specific agent. There is currently no evidence-based way to identify the patients that will respond to a specific preventive treatment. Amitriptyline is one of the commonest agents used for migraine prevention, strengthening patient's pain inhibitory capacity. Individual tailoring of analgesics according to pain inhibitory capacity has been shown effective by our group for painful diabetic neuropathy patients. Specifically, patients with reduced pain inhibition capacity gained more from a drug that augment pain inhibition as compared to those with efficient inhibitory capacity. The investigators now propose to assess migraineurs for their pain inhibition capacity, and examine whether, along similar reasoning, those with reduced inhibitory capacity are the ones more likely to respond to amitriptyline. Psychophysical and neurophysiological dimensions of pain inhibitory modulation will be assessed in migraineurs, who will, subsequently, receive either amitriptyline or placebo for 8 weeks, in a randomized two arms parallel double blind design, and followed up for attacks reduction. The investigators expect to identify the best predictors for efficacy of migraine prevention by the study drug. This approach will promote individualization of migraine therapy.

In a double blind placebo-controlled cross-over study the effect of cilostazol on aura induction and endothelial response is tested in patient with migraine with aura.

In a double blind placebo-controlled cross-over study the effect of Sildenafil on aura and migraine headache induction is tested in patient with migraine with aura.

The purpose of this trial is to study the use of soy isoflavones in the prevention of menstrually-associated migraines. Additionally, this trial may provide insight into the menstrual cycle and menstrually-related headaches in women. With this information, we may be able to change current treatment methods or even develop new methods in order to advance current approaches in the treatment of menstrual migraine.

Background: Medically intractable chronic migraine (CM) is a disabling illness characterized by headache greater than 15 days per month. Method: A multicenter, randomized, blinded, controlled feasibility study was conducted to obtain preliminary safety and efficacy data on occipital nerve stimulation (ONS) in CM. Eligible subjects received an occipital nerve block, and responsers were randomized to adjustable stimulation (AS), preset stimulation (PS) or medical management (MM) groups.

The objective of this study is to assess the long-term safety and effectiveness of topiramate in the prevention of basilar and hemiplegic migraine in children and adolescents.

This study will examine the influence of stress and fasting on headache activity. Participants will receive both a control and stress session and be randomized to either fasting or not fasting for the visits.
