Safety and Efficacy Trial of MTX101 2mg for the Acute Treatment of Migraine in Adults

The goal of this clinical trial is to learn if drug MTX101 works to treat acute migraine attacks in adults. It will also learn about the safety of the drug MTX101. The main questions it aims to answer are:

Does the drug MTX101 lower headache pain for participants and the need to use a rescue medication? What side effects, if any, do participants have when taking the drug MTX101? Researchers will compare the drug MTX101 to a placebo (a look-alike substance that contains no drug) to see if the drug MTX101 works to treat acute migraine attacks.

Participants will:

Take the drug MTX101 or a placebo to treat 1 migraine attack with each treatment.

Visit the clinic twice and have one phone call over a 4 week period for checkups and tests.

Keep a diary of their symptoms and the number of times they use a rescue medication.

About this study

Subjects enrolled in the study will be randomized to receive investigational product (MTX101 2mg or placebo), to be taken as soon as they have a migraine headache that reaches moderate to severe intensity. Subjects will take a single dose of either active or placebo to treat one migraine headache. Rescue medication should not be taken until at least 2 hours post study medication dose.

The subject will have a telephone check up within 72 to 120 hours after treatment of the first migraine headache.

The subject will treat a 2nd moderate to severe migraine at least 48 hours after the first treated migraine headache.

The subject will return to the clinic for re-evaluation within a 4 week period from the start of the study.

Treatment and study plan

MTX101

Drug

One 2 mg sublingual tablet of MTX101

Placebo

Drug

One sublingual tablet of placebo

Primary outcomes

  1. Safety assessment (occurrence of adverse events, treatment emergent adverse events and serious adverse events).

    Time frame: Treatment emergent adverse event safety assessments will be limited to the first 48 hours after a treated attack.

    To assess the tolerability and safety of MTX101. This objective will be measured by assessing the number of unique subjects with deaths, serious adverse events, and moderate and severe adverse events.

Secondary outcomes

  1. The change in migraine headache pain score, using an 11-point Numerical Rating Scale, (0=no pain, 10=worst possible pain).

    Time frame: From the time of dosing (t=0 hour) to 2 hours post-dose.

    This objective will be measured by change in migraine headache pain score, using an 11-point Numerical Rating Scale, (0=no pain, 10=worst possible pain), from the time of dosing (t=0 hour) to 2 hours post-dose as recorded on the subject's Diary.
