What is being measured

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

  1. Pain freedom at 2 hours post-dose

    Percentage of participants that report no pain at 2 hours post-dose. Pain will be measured on a 4-point Likert scale (0=none, 1=mild, 2=moderate, 3=severe).

    Measured: Two hours post-dose

  2. Freedom from most bothersome symptoms (MBS) at 2 hours post-dose

    Percentage of participants that report absence of their MBS (nausea, phonophobia, or photophobia) at 2 hours post-dose. MBS will be measured using a binary scale (0=absent, 1=present).

    Measured: Two hours post-dose

Secondary outcomes (14)
  1. Pain relief at 2 hours post-dose

    Percentage of participants that report a pain level of moderate of severe (responses of 2 or 3 on the 4-point Likert scale) at baseline and then report a pain level of none or mild (responses of 0 or 1 on the 4-point Likert scale) at 2 hours post-dose.

    Measured: Two hours post-dose

  2. Sustained pain freedom from 2 to 48 hours post-dose

    Percentage of participants that do not use any rescue medication, do not experience any headache pain through the time period of interest, and do not have missing pain data at 2, 24, or 48hours post-dose.

    Measured: From 2 to 48 hours post-dose

  3. Freedom from functional disability at 2 hours post-dose

    Percentage of participants that self-report as being able to function normally on the functional disability scale in the subset of participants that reported any level of disability at baseline. The scale has a 4-point numeric rating: normal (0); mildly impaired (1); moderately impaired (2); severely impaired, requires bedrest (3).

    Measured: Two hours post-dose

  4. Pain relief at 60 minutes post-dose

    Percentage of participants that report a pain level of moderate of severe (responses of 2 or 3 on the 4-point Likert scale) at baseline and then report a pain level of none or mild (responses of 0 or 1 on the 4-point Likert scale) at 60 minutes post-dose

    Measured: Sixty minutes post-dose

  5. Proportion requiring rescue medication within 24 hours post-dose

    Percentage of participants that take rescue medication within 24 hours post-dose.

    Measured: Within 24 hours post-dose

  6. Freedom from photophobia at 2 hours post-dose

    Percentage of participants that report the absence of photophobia at 2 hours post-dose in the subset of participants that reported the presence of photophobia at baseline.

    Measured: Two hours post-dose

  7. Freedom from phonophobia at 2 hours post-dose

    Percentage of participants that report the absence of phonophobia at 2 hours post-dose in the subset of participants that reported the presence of phonophobia at baseline.

    Measured: Two hours post-dose

  8. Freedom from nausea at 2 hours post-dose

    Percentage of participants that report the absence of nausea at 2 hours post-dose in the subset of participants that reported the presence of nausea at baseline.

    Measured: Two hours post-dose

  9. Sustained pain freedom from 2 to 24 hours post-dose

    Percentage of participants that do not use any rescue medication, do not experience any headache pain through the time period of interest, and do not have missing pain data at 2 or 24 hours post-dose.

    Measured: From 2 to 24 hours post-dose

  10. Sustained pain relief from 2 to 48 hours post-dose

    Percentage of participants that do not use any rescue medications, do not experience any moderate or severe headache pain through the time period of interest, and do not have missing pain data at 2, 24, or 48 hours post-dose.

    Measured: From 2 to 48 hours post-dose

  11. Sustained pain relief from 2 to 24 hours post-dose

    Percentage of participants that do not use any rescue medications, do not experience any moderate or severe headache pain through the time period of interest, and do not have missing pain data at 2 or 24 hours post-dose.

    Measured: From 2 to 24 hours post-dose

  12. Pain relapse from 2 to 48 hours post-dose

    Percentage of participants that are pain free at 2 hours post-dose and have (a) mild, moderate, or severe pain (response of 1, 2, or 3 on the 4-point Likert scale) at any time point after 2 hours post-dose, or (b) missing pain data at 24 hours or 48 hours after 2 hours post-dose, or (c) intervening rescue medication use at or before 48 hours post-dose.

    Measured: From 2 to 48 hours post-dose

  13. Percentage of participants who experience one or more treatment-emergent adverse events (AEs)

    Measured: Up to 8 days post-dose

  14. Percentage of participants who experience one or more treatment-emergent serious adverse events (SAEs)

    Measured: Up to 8 days post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Elismetrep in people with Migraine, run by TriGemX Bio, Inc. at 113 sites 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 16 inclusion and 44 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: looking for participants now, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 113 sites 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. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Annemarie Vance (917-336-3654, annemarie@kallyope.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain freedom at 2 hours post-dose (time frame: Two hours post-dose). 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 2 Nov 2026.
