  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • A diagnosis of episodic cluster headache according to the International Classification of Headache Disorders 3rd edition as well as cluster periods that are predictable and have a duration of 6 weeks or greater and approximately one attack daily minimum OR
  • A diagnosis of chronic cluster headache according to the International Classification of Headache Disorders 3rd edition as well as approximately one attack daily
  • Participants who are unlikely to need to change their preventive cluster headache treatment regimen in the next 6 weeks.

Who cannot join

  • Co-existing disease or other characteristic that precludes appropriate diagnosis of cluster headache.
  • Active drug or alcohol use or dependence that, in the opinion of the site investigator,would interfere with adherence to study requirements.
  • Inability or unwillingness of subject to give informed consent.

  • Concurrent use of Vitamin D and/or multivitamin along with the inability to stop them before the study begins.
  • Liver failure or known coagulation disorder (as this study includes vitamin K) such as haemophilia, von Willebrand disease, Factor V Leiden, Antithrombin III deficiency, Protein C or S deficiency, or anti-phospholipid antibody syndrome.
  • A personal medical history of more than 1 deep venous thrombosis and/or pulmonary embolism (as this study includes vitamin K).
  • Current use of anticoagulants (as this study includes vitamin K). Anticoagulants include: apixaban (Eliquis), betrixaban (Bevyxxa), dabigatran (Pradaxa), dalteparin (Fragmin), edoxaban (Savaysa), enoxaparin (Lovenox), fondaparinux (Arixtra), heparin, rivaroxiban (Xarelto), and warfarin (Coumadin).
  • Current use of medications that alter vitamin D metabolism, including steroids,interferon, phenytoin, phenobarbital, digitalis/digoxin, and thiazide diuretics (such as hydrochlorothiazide or chlorthalidone)
  • Participants who are aware that their most recent labwork in the last 2 years showed any of the following:
  • 25-hydroxyvitamin D levels >75 nmol/L
  • Elevated calcium level
  • Elevated phosphate level
  • Abnormal parathyroid hormone levels
  • Elevated creatinine level
  • Of note if any values are outside the acceptable range for the study, candidates may still participate in the study if the most recent lab testing is inside the acceptable range for the study. For example, if a candididate were taking a vitamin or medication that may have caused these elevated levels, but no longer take the vitamin or medication, they may be enrolled if retesting is normal.

About this study

Official title: High Dose Vitamin D Plus Multivitamin in the Prevention of Cluster Headache: a Randomized, Double-blind, Placebo Controlled Trial.

This study intends to investigate the use of high-dose Vitamin D3 plus a multivitamin in the prevention of cluster headache attacks.

Participants can be enrolled anywhere in the United States that has access to one of our participating labs (for blood work - anticipated to be available in most of the USA).

The study may include:

  • Screening: Participants may be interviewed, examined, fill out surveys, and get blood testing
  • Week 1: baseline period (no added medications - to establish a baseline)
  • Weeks 2-4: double-blinded experimental period - participants receive either 1) high-dose Vitamin D3 + multivitamin, or 2) placebo + multivitamin. Participants also fill out a survey and have blood testing.
  • Weeks 5-7: open-label period - ALL participants receive high-dose Vitamin D3 + multivitamin. Participants also fill out a survey and may have blood testing.

Specifically, our primary outcome is the change from baseline to experimental weeks 1-3 in the frequency of cluster headache attacks between placebo and high-dose vitamin D. Specific primary and secondary outcomes are listed below.

Questions about this trial

What is this clinical trial studying?

A study testing Vitamin D and multivitamin in people with Cluster Headache, run by The University of Texas Health Science Center, Houston at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 6 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Low number met criteria to randomize.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in average weekly frequency of cluster headache attacks (time frame: (baseline, average of weeks 1-3)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2025.
