Although the latter compounds have shown some efficacy in reducing the attack frequency, the evidence for their effect is weak. All current prophylactics are prescribed off-label and are limited in their utility due to associated side effects. Despite treatment, many (notably chronic) cluster headache patients continue suffering headache attacks.\n\nInvasive, expensive treatments like hypothalamic deep brain stimulation, occipital nerve stimulation and sphenopalatine ganglion stimulation are last resort options. Recently, a monoclonal antibody targeting calcitonin gene related peptide (CGRP) received FDA approval for episodic cluster headache, but was shown to be ineffective in cCH. Thus, there is a considerable unmet need for effective treatments that are better tolerated, safe and affordable.\n\nIn this study, the investigators will assess the efficacy of prophylactic treatment with LSD in cCH. The evidence for the efficacy of LSD is limited, with the majority of data originating from case reports or uncontrolled and retrospective (internet) surveys. Nevertheless, these studies do provide indications that LSD may hold potential as a cluster headache prophylaxis.\n\nThe primary objective of this randomized double-blind placebo-controlled trial is to compare the efficacy of LSD 25μg every 3 days for 3 weeks versus placebo in cCH. The investigators aim to show that, at the end of treatment, verum is more efficacious than placebo with comparable tolerability in an ambulatory setting. To explore the sustainability of benefit the investigators will also assess the (sustained) response at 5 weeks post-treatment (8 weeks postrandomization).\n\nIf the study findings are positive, LSD should be further studied before use in routine clinical practice. Non-hallucinogenic low-dosed LSD may provide an alternative or adjunctive option for patients who do not respond to or cannot tolerate currently available treatments.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '16 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* CCH according to the International Classification of Headache Disorders version 3 (ICHD-3)\n* At screening: stable weekly attack frequency in the 4 weeks prior to screening (assessed retrospectively), averaging at least 8 per week and each week within a 40% window around the average\n* At randomization: average of at least 8 attacks per week and no absence of attacks on more than two consecutive days during baseline\n\nExclusion Criteria:\n\n* Use of excluded concomitant treatment at screening (lithium; other prophylactics if not on a stable dose for less than one month; steroids/GON block within 2 months before screening; sphenopalatinum block, neurostimulation (changed setting within 3 months before screening) or botulinum toxin within 3 months before screening) and during the double-blind phase\n* Use of LSD(-derivatives) (other than investigational drug), psilocybin, ketamine or cannabis within 3 months prior to screening and throughout the study\n* Lifetime and/or family history (first degree relatives) of psychotic or bipolar disorder, suicidal intention or attempt\n* A score of 6 or more on the 'Ervaringenlijst' (PQ-16) to exclude subclinical susceptibility to psychosis\n* Actual abuse of alcohol and/or recreational drugs\n* Lifetime history of cardiac valvular disease\n* History or evidence of cognitive disorder at screening\n* Positive urine drug screen at screening\n* Females: Pregnancy, lactation, no acceptable contraceptive use"}, 'identificationModule': {'nctId': 'NCT05477459', 'acronym': 'LICIT', 'briefTitle': 'LSD to Improve Cluster Headache Impact Trial', 'organization': {'class': 'OTHER', 'fullName': 'Radboud University Medical Center'}, 'officialTitle': 'Efficacy and Safety of Minidosing Lysergic Acid Diethylamide (LSD) for Chronic Cluster Headache: a Randomized Placebo-controlled Study', 'orgStudyIdInfo': {'id': '131-2022'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Verum', 'description': 'Lysergic diethylamide tartrate (equivalent to 25 microgram LSD base), one dose every 3 days for 3 weeks (totalling 7 vials)', 'interventionNames': ['Drug: LSD tartrate']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'Placebo vial looking like verum vial, one vial every 3 days for 3 weeks (totalling 7 vials)', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'LSD tartrate', 'type': 'DRUG', 'otherNames': ['Lysergic acid diethylamide'], 'description': 'LSD tartrate equivalent to 25 microgram LSD base', 'armGroupLabels': ['Verum']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'Placebo with equal appearance', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Leiden', 'status': 'RECRUITING', 'country': 'Netherlands', 'contacts': [{'name': 'Martien van Liefland', 'role': 'CONTACT', 'email': 'LICIT@LUMC.nl', 'phone': '071 526 21 11'}, {'name': 'Rolf Fronczek, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Martien van Liefland, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': 'Leiden University Medical Center (LUMC)', 'geoPoint': {'lat': 52.15833, 'lon': 4.49306}}, {'city': 'Nijmegen', 'status': 'RECRUITING', 'country': 'Netherlands', 'contacts': [{'name': 'Julia Jansen', 'role': 'CONTACT', 'email': 'LICIT@cwz.nl', 'phone': '024 365 82 10'}, {'name': 'Willemijn Leen, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}, {'name': 'Julia Jansen, MD', 'role': 'SUB_INVESTIGATOR'}], 'facility': 'Canisius-Wilhelmina Ziekenhuis (CWZ)', 'geoPoint': {'lat': 51.8425, 'lon': 5.85278}}], 'centralContacts': [{'name': 'Julia Jansen, MD', 'role': 'CONTACT', 'email': 'julia.jansen@cwz.nl', 'phone': '+31 24 3658765'}], 'overallOfficials': [{'name': 'Kees Kramers, Prof.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Radboud University Medical Center'}]}, 'ipdSharingStatementModule': {'infoTypes': ['STUDY_PROTOCOL'], 'timeFrame': '9-36 months after article publication', 'ipdSharing': 'YES', 'description': 'Individual patient data underlying publication, after deidentification, will be shared upon request to the corresponding author', 'accessCriteria': 'For purpose of meta-analysis and approved by an independent review board'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Radboud University Medical Center', 'class': 'OTHER'}, 'collaborators': [{'name': 'ZonMw: The Netherlands Organisation for Health Research and Development', 'class': 'OTHER'}, {'name': 'Canisius-Wilhelmina Hospital', 'class': 'OTHER'}, {'name': 'Leiden University Medical Center', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
