Filter by:The purpose of this study is to validate the novel hypothesis that daily use of L-cysteine (Acetium® capsules) is an effective means to decrease the frequency of (or completely abort) the attacks of cluster headache.
This is a double-blinded, randomized, parallel, placebo-controlled phase 2 study to evaluate the safety and efficacy of R-verapamil in the prophylaxis of episodic cluster headache.
The primary objective of the study is to demonstrate the safety and efficacy of SPG stimulation with the ATI Neurostimulation System when used to treat acute cluster attacks in chronic cluster headache patients.
The occipital nerve stimulation (ONS) is used to treat patients with refractory primary chronic headache but its mechanism of action (MoA) remains unknown. Different hypothesis have been suggested in particular a specific action on cerebral generators involved in different types of primary headaches or a non specific action on pain modulatory network. The aim of this study, using the chronic cluster headache as a model, is to determine the changes in cerebral metabolism induced by ONS to precise its MoA in the treatment of primary chronic headache.
Cluster headache is an intense and powerful, one-sided headache accompanied by involuntary symptoms such as red eye, droopy eyelids, flow of tears, small pupils and one-sided facial sweating. The headache is believed to be the most intense of all headaches and among many is totally disabling and of great personal and social consequences. For a small group of patients with episodic and most chronic form, drug therapy has little effect. For them, surgery can be a solution. Neuroradiology has found evidence of a possible original activation of cluster headache from the portion of the brain called hypothalamus. Furthermore, an activation of the parasympathetic nervous system through the sphenopalatine ganglion, which may also explain some of the one-sided involuntary symptoms, is suspected in cluster headache. Injection of Botulinum toxin type A (BTA) inhibits secretion of synaptic acetylcholine resulting in nerve signals being blocked. The duration of such a blockade is believed to be 3-9 months. The purpose of the present study is to develop and evaluate a new surgical procedure with injection of BTA for blocking of the sphenopalatine ganglion. The goal is to relieve the symptoms of refractory cluster headache with a minimal invasive procedure. The main objective of the project is to determine the safety of BTA injection in the area of the sphenopalatine ganglion of refractory cluster headache and detect the adverse events. Secondary objectives are to identify the changes of headache attacks by the method used.
The study will look at a non-invasive treatment for people suffering with chronic and episodic headaches. Study subjects will be randomized to an active treatment or an in-active treatment for 2 weeks. After the 2 weeks all subjects will continue to treat with an active treatment for an additional 2 weeks.
This study will be looking at the clinical efficacy of using a intranasal evaporative cooling device in providing relief of the symptoms of migraine and cluster headache. It will involve using a nasal catheter to spray a liquid coolant into the nasal cavity where it evaporates and removes heat from the tissue, thereby cooling the tissue and the blood vessels which supply blood to the brain. This cooling effect will cause the blood vessels to constrict and it is thought that this may provide symptomatic relief in both these forms of headache. 10 migraine patients and 5 cluster headache patients will be enrolled in the study and will receive 10 treatments each, for a maximum of 20 minutes at a time. They will be monitored during the treatment and for two hours afterwards to assess headache severity and side effects. There will be a further follow up 2 months after the last treatment to assess for longer term side effects from the treatment.
Multi-center, prospective, double-blind, randomized, sham-controlled pivotal study of non-invasive vagus nerve stimulation with the GammaCore® device for the acute treatment of cluster headache. The study compares the safety and effectiveness of an active treatment (GammaCore) against a sham treatment.
Subjects enrolled into this 10 week study will for the first two weeks document the number of cluster headaches and the means of treating (medication) of these attacks. Subjects will then be randomized to into either two groups. The first group is continuing with standard of care and the second group is treatment with the investigational device (GammaCore) for a period of 4 weeks. After this 4 week period, all subjects will treat with the GammaCore for another 4 week period. It is hypothesized the the treatment group will have a reduction in mean cluster headaches per week by 50% compared to the standard of care group.
The primary objectives of the Registry are to: 1. Monitor the transfer of the ATI Neurostimulation System and its safety/clinical performance to a larger number of centers in the post market phase and 2. Collect additional evidence to support reimbursement and clinical acceptance and long term follow up
