Novel Therapies in Acute Migraine Management: Small-Molecule Calcitonin Gene-Receptor Antagonists and Serotonin 1F Receptor Agonist.

OBJECTIVE

To review the efficacy, safety, and cost of 3 newly approved agents-ubrogepant, lasmiditan, and rimegepant-representing 2 therapeutic classes, calcitonin gene-related peptide (CGRP) receptor antagonist and serotonin 1F (5-HT) agonists, for the acute treatment of migraine with or without aura.

DATA SOURCES

The Institute of Health US National Library of Medicine Clinical Trials, PubMed, and Cochrane databases were queried. Abstracts, journal articles, and other relevant sources published or present were reviewed. Search terms included the following: .

STUDY SELECTION AND DATA EXTRACTION

Relevant English-language articles from June 30, 2010, to August 31, 2020, were evaluated and included in the narrative.

DATA SYNTHESIS

CGRP receptor antagonists, ubrogepant and rimegepant, achieved 2-hour pain freedom and freedom from the most bothersome migraine symptom (MBS) at 2 hours. Both agents were well tolerated, with adverse effects similar to placebo. Lasmiditan, a 5-HT receptor antagonist, also improved 2-hour pain freedom and freedom from the MBS at 2 hours. Lasmiditan is associated with dizziness, paresthesia, somnolence, nausea, fatigue, and lethargy.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

Ubrogepant, rimegepant, and lasmiditan represent a new and exciting chapter in acute migraine therapy. To date, no head-to-head studies have compared these agents with the triptans. Ubrogepant and lasmiditan are effective in triptan nonresponders. None of the 3 agents is contraindicated in cardiovascular disease, unlike the triptans.

CONCLUSIONS

Based on available data, ubrogepant, rimegepant, and lasmiditan should be reserved as second-line therapy and may be safe in patients with cardiovascular risk. Lasmiditan's adverse effect profile may limit its use.
