Active clinical trials for "Cluster Headache"

Cluster headache is a disorder marked by frequent attacks of short-lasting, severe, unilateral head pain with associated autonomic symptoms. It is the most severe head pain syndrome known. Currently, the two most common treatments for cluster headaches are inhaled oxygen and injectable sumatriptan. These treatments do not work for all cluster headache patients, and patients who smoke may eventually develop contraindication to triptans. New treatment options are needed. An alternative method of oxygen delivery (as opposed to continuous flow) uses a demand valve that is controlled by respiration rate, allowing increased oxygen flow in response to increased demand. This system may be more efficacious at stopping a cluster headache attack than the currently prescribed oxygen delivery system. This study will compare the effectiveness of oxygen delivered via demand valve versus continuous high flow oxygen via non-rebreather face mask in the acute treatment of a cluster headache attack. All patients will treat one cluster headache with each of the 2 treatment methods.

The purpose of this study was to determine if SOM230 is safe and effective for the treament of cluster headache.

Topiramate is a medication that has been approved by the Food and Drug Administration (FDA) for the treatment of patients with seizures. The trade name for this drug is Topamax®. Topiramate has not been approved by the FDA for the treatment of cluster headache and is experimental for the purposes of this research study. If a subject participates in this study, he/she will increase his/her dose of topiramate rapidly in the first few weeks to try to stop the cluster attacks and then will continue on a maintenance dose of topiramate in order to determine if it can prevent attacks from occurring during that cluster period. We believe that this will lead not only to a faster but a more complete remission of the cluster period.

Cluster headache is also called suicide headache due to excruciating nocturnal attacks. There are few treatment options available. Inhalation of oxygen has shown to abort the attacks. Continuous positive airway pressure (CPAP) is a machine used during sleep to treat respiratory failure. Automatic CPAP machines adjust the air pressure through the night to keep the upper airways patent. Single reports have shown a high prevalence of obstructive sleep apnea in people suffering from cluster headache, and positive effects of CPAP treatment, but no randomized controlled trial has been conducted so far. If proven effective CPAP would make an affordable treatment option for many patients within the existing healthcare system.

The investigators aim to investigate the effectiveness and safety of sphenopalatine ganglion pulsed radiofrequency on cluster headache.

The purpose of the proposed clinical study is to evaluate the use of an implanted Neurostimulator to provide Sphenopalatine Ganglion (SPG) stimulation for the management of the pain associated with cluster headaches.

The purpose of this study is to collect and evaluate information on the use of Depakote Extended Release (ER) and Depacon Intravenous (IV) in patients with cluster headaches. Patients who are currently in a cluster cycle will be treated with 2 consecutive days of IV Depacon followed by oral Depakote ER. Patients will receive a total of 1,000mg of Depacon and 1,000mg of Depakote ER each day. Patients may have a 3rd day of IV Depacon followed by oral Depakote ER if the primary investigator believes it to be beneficial. The patient is then sent home on oral Depakote ER. The dose of Depakote ER can range from 500mg to 2,000mg this dose is to be determined by the primary investigator. The patient will continue the oral Depakote ER until the end of their cluster cycle or for a maximum of 6 weeks, which ever comes first.

The purpose of this study is to determine whether candesartan cilexetil are effective prophylactic treatment of episodic Cluster headache

This is a 49-day study to evaluate the effectiveness of Intranasal Civamide (Zucapsaicin) in the treatment of an episodic cluster headache period compared to placebo (medically inactive substance which does not contain any active ingredients).

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.
