Active clinical trials for "Cluster Headache"

The purpose of this study is to demonstrate the safe use of a novel cranio-facial Peripheral Nerve Stimulator PNS System in subjects with chronic cluster headache. This is a single-centre, open label, prospective, first in human study to collect initial clinical data on the PNS System for the treatment of chronic cluster headache.

The purpose of this study is to evaluate the efficacy of eptinezumab in participants with episodic Cluster Headache (eCH)

The purpose of this study is to investigate the effects of an oral psilocybin pulse regimen in cluster headache. Subjects will be randomized to receive oral placebo, low dose psilocybin, or high dose psilocybin in three experimental sessions, each separated by 5 days. Subjects will maintain a headache diary prior to, during, and after the pulse regimen in order to document headache frequency and intensity before, during, and after the pulse regimen. After at least 6 months from the last experimental session, subjects may be invited for a second round, in which they will be randomized to receive either low dose or high dose psilocybin.

Background: - The effect of repeated GON-injections has never been studied in a double-blind randomized trial as a prophylactic therapy in a well-documented group of chronic patients. As such, (repeated) GON-injection has not yet found its place in current (inter)national treatment protocols for chronic cluster headache. Objectives: - The primary objective is to determine if repeated GON-injection result in effective control of cluster headache attacks for more days compared to placebo in chronic cluster headache. Eligibility: - Patients will be selected from the LUMC (Leiden University Medical Center) and CWZ (Canisius Wilhelmina Hospital) chronic cluster headache populations, diagnosed based upon the ICHD-3. Design: - Bi-centre, randomized, double-blind, placebo-controlled retention trial with a maximum follow-up of one year.

The objective of this study is to survey patients with cluster headache about treatment effectiveness and their views on treatments. Participants will complete one brief questionnaire online.

This study aims to investigate the efficacy and safety of LSD 25μg every 3 days for 3 weeks versus placebo in the treatment of chronic cluster headache (cCH). It is a 3-week double-blind placebo-controlled intervention study, preceded by a 4-week baseline observation period and followed by a 5-week post-treatment observation period. Primary objective: to evaluate the efficacy of LSD 25μg every 3 days for 3 weeks in cCH. Additional objectives: To evaluate the safety of LSD 25μg every 3 days for 3 weeks in cCH. To explore the exposure-response relationship of 25μg LSD in cCH. To assess the effect of treatment with 25μg LSD on hypothalamic functional connectivity in patients with cCH, using resting state functional magnetic resonance imaging (rsMRI). To explore cost-effectiveness of treatment with LSD in cCH. To evaluate the efficacy of LSD on health-related quality of life.

In the Chinese Headache and Vertigo Registration Study, patients aged 4-99 years with headache (primary headache and secondary headache such as migraine and tension type headache), vertigo (vertigo diseases such as vestibular migraine) and chronic pain (fibromyalgia and other diseases) were collected. The biomarkers, imaging features, right-to-left shunt of the heart (lung), genetic characteristics, treatment, and outcome (in relation to other diseases) of headache-related diseases were studied, and long-term follow-up was planned.

The main purpose of this study is to evaluate the efficacy of erenumab in participants with chronic cluster headache.

This study investigates molecular and physical biomarkers of headaches in order to better understand mechanisms of these diseases. There are 3 main parts: Use of capsaicin (active ingredient in hot chili peppers) to trigger release of calcitonin gene related peptide - the hypothesis is that this will be different in headache subjects compared to controls (and if so might be used to predict how these patients will respond to certain medications that modulate calcitonin gene-related peptide). Subjects will be given capsaicin as a cream applied to the forehead or the inner nostril, or a hot sauce that is ingested. Use of capsaicin to trigger eye watering - the hypothesis is that oxygen gas will slow down the amount of eye watering. Cluster headache patients respond very powerfully to oxygen gas but to very little else. The mechanism for oxygen is unknown but in rodents there is data that it works on the parasympathetic / lacrimal gland system. This study translates rodent data into humans in a non-invasive way to confirm the mechanism of this very effective treatment. Use of ice water to trigger headaches - brain freeze causes a very short-lived but intense headache that may cause similar biomarker release as other headache disorders. This may be a useful human model for other headache disorders.

The purpose of this study is to evaluate the safety and efficacy of intranasally administered civamide nasal solution in the prevention of cluster headaches during an episodic cluster headache period.
