Trial Summary

What is the purpose of this trial?

This trial aims to test the safety of rimegepant, a medication for treating migraines. The study focuses on children and adolescents aged 6 to 17 years who experience moderate to severe migraines. Rimegepant works by blocking a protein that triggers migraine pain, helping to alleviate symptoms.

Will I have to stop taking my current medications?

The trial allows participants to continue taking their current migraine prevention medication if the dose has been stable for at least 12 weeks before the study starts. The protocol does not specify about other medications, so it's best to discuss with the trial team.

Is Rimegepant safe for humans?

Rimegepant has been generally well tolerated in clinical trials for migraine treatment in adults, with no evidence of liver or heart toxicity. Most side effects were mild or moderate and did not lead to stopping the trials. ^{1 2 3 4 5}

How is the drug Rimegepant unique for treating pediatric migraine?

Rimegepant is unique because it is a calcitonin gene-related peptide (CGRP) receptor antagonist available as an orally disintegrating tablet, which can offer convenience and potentially faster relief compared to conventional tablets. It is the first drug approved for both the acute treatment and prevention of migraine, making it a versatile option for managing migraines. ^{1 3 4 6 7}

Findings from Research

Rimegepant is an effective treatment for migraines, showing significant pain relief and reduction in bothersome symptoms compared to placebo in phase III trials, and it can also reduce the number of monthly migraine days when used preventively.

The medication is generally well tolerated, with no signs of liver or heart-related side effects, making it a safe option for adults managing migraines.

Rimegepant: A Review in the Acute Treatment and Preventive Treatment of Migraine. Blair, HA.[2023]

Rimegepant significantly improves outcomes for migraine patients, including freedom from pain and pain relief at 2 hours, with odds ratios indicating strong efficacy compared to placebo.

The treatment shows sustained benefits at 24 hours and does not appear to increase the risk of adverse events, suggesting it is a safe option for migraine management.

Efficacy and Safety of Rimegepant for Migraine Patients: A Meta-analysis of Randomized Controlled Studies. Yang, C., Zhang, Y.[2023]

In a study involving 13 patients with migraines, rimegepant was found to be well tolerated when used as an acute treatment alongside CGRP monoclonal antibodies (mAbs) for preventive treatment, with no serious adverse events reported.

Out of the patients, 38% experienced mild to moderate adverse events, primarily nasopharyngitis, indicating that while some side effects occurred, they were generally not severe and did not lead to treatment discontinuation.

Safety of Rimegepant, an Oral CGRP Receptor Antagonist, Plus CGRP Monoclonal Antibodies for Migraine. Berman, G., Croop, R., Kudrow, D., et al.[2021]

Rimegepant, taken every other day, significantly reduced the mean number of migraine days per month compared to placebo, with a difference of -0.8 days, indicating its efficacy as a preventive treatment for migraines.

The safety profile of rimegepant was comparable to that of placebo, with similar rates of adverse events and no serious safety concerns reported during the study involving 747 participants.

Oral rimegepant for preventive treatment of migraine: a phase 2/3, randomised, double-blind, placebo-controlled trial. Croop, R., Lipton, RB., Kudrow, D., et al.[2021]

In a phase 3 trial involving 1466 participants, the orally disintegrating tablet formulation of rimegepant (75 mg) was significantly more effective than placebo in providing freedom from pain (21% vs 11%) and freedom from the most bothersome symptom (35% vs 27%) at 2 hours post-dose.

The safety profile of rimegepant was comparable to placebo, with no serious adverse events reported, and the most common side effects were mild, such as nausea and urinary tract infections, indicating good tolerability.
