What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • LevcromakalimDrug

    Study participants will be allocated to receive continuous intravenous infusion of 0.05 mg/min (20 ml of 50 mg/ml) levcromakalim.

  • PlaceboDrug

    Also called Isotonic Saline

    Study participants will be allocated to receive continuous intravenous infusion of 20 mL placebo (isotonic saline).

Study groups in NCT05243953
Study groupRoleWhat they receive
LevcromakalimExperimentalA time- and volume-controlled infusion pump is used to administer levcromakalim by intravenous infusion over 20 minutes.
Receives: Drug: Levcromakalim
Placebo (isotonic saline)Placebo comparatorA time- and volume-controlled infusion pump is used to administer placebo (isotonic saline) by intravenous infusion over 20 minutes.
Receives: Drug: Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Migraine-Like Headache

    Difference in incidence of headache with migraine-like features (0 to 12 hours) between levcromakalim and placebo.

    Measured: 12 Hours

Secondary outcomes (1)
  1. Headache Intensity Scores

    Difference in area under the curve (AUC) for headache intensity scores (0 to 12 hours) between levcromakalim and placebo.

    Measured: 12 Hours

Questions about this trial

What is this clinical trial studying?

A study testing Levcromakalim in people with Post-Traumatic Headache, run by Danish Headache Center at 1 site in Denmark.

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 4 inclusion and 15 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: finished, as of the sponsor's last update on 8 Jul 2022. 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 Denmark. 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. Some participants in this study may receive a placebo. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Incidence of Migraine-Like Headache (time frame: 12 Hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05243953, which also lists 1 linked publication.

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 8 Jul 2022.
