About this study

Official title: How to Predict Response to Acute Treatment of Migraine With Rimegepant 75 mg: a Biochemical and Neurophysiological Study.

Tools to predict which patients could better respond to abortive CGRP target therapy are still lacking. We propose to investigate if biochemical (salivary CGRP) and neurophysiological (evoked potentials) biomarkers can recognize patients with the best chances of responding to Rimegepant 75 mg as an acute treatment of migraine.

Read the detailed description

Background: The understanding of the central role of CGRP in migraine pathophysiology led to the development of new target therapies against this molecule pathway, including Rimegepant. Despite the central role of the CGRP pathway in migraine, it was recently discovered that some migraine attacks are non CGRP-dependent. Tools to predict which patients could better respond to abortive CGRP target therapy are still lacking.

Objective: We propose to investigate if biochemical (salivary CGRP) and neurophysiological (evoked potentials) biomarkers can recognize patients with the best chances of responding to Rimegepant 75 mg as an acute treatment of migraine.

Design of the study and methods: This will be a prospective observational study. The study will be subdivided into four phases: screening visit (T0), salivary collection, observational phase, follow-up visit (T1). At the screening visit (T0) patients with episodic migraine (20 patients), which will be prescribed Rimegepant 75 mg as abortive treatment, will be asked to participate in the study. During the salivary collection phase, patients will be instructed to collect daily saliva samples for a minimum of 7 days and a maximum of 14 days to include a minimum of 1 migraine attack. During the observational phase (1-month duration) patients will take Rimegepant 75 mg for abortive treatment of migraine attacks and, they will be instructed to take extra saliva samples (headache onset, after 2h and 8h) at each migraine attack. Neurophysiological procedures (somatosensory evoked potentials and nociceptive blink reflex) will be recorded at baseline (T0) and after 1 month (follow-up visit, T1) of administration of Rimegepant 75 mg as an abortive migraine treatment. We chose somatosensory evoked potentials (SSEPs) to assess the integrity of the non-pain-related somatosensory lemniscal system and to study habituation phenomena, and nociceptive blink reflex (nBR) to investigate the activity of the caudal trigeminal nucleus. CGRP salivary levels will be quantified with ELISA kit.

Specific aim: We aim to predict Rimegepant (used as abortive therapy) response from baseline CGRP salivary levels and neurophysiological parameters (habituation and sensitization from somatosensory evoked potentials and nociceptive blink reflex). Mixing and comparing these two approaches could help to find a combination of biomarkers able to predict the treatment success. We hypothesize that patients with marked habituation deficit, less sensitization, and more elevated CGRP salivary levels during the attack will be the patients who will respond the most to Rimegepant 75 mg as abortive migraine therapy.

  3. Changes from Baseline in the pain threshold after 1 month of therapy

    Comparison between pain threshold (mA) at baseline and pain threshold (mA) after one month of abortive therapy with Rimegepant 75 mg

    Measured: one month after the start of therapy

  4. Changes from Baseline in the sensory detection threshold after 1 month of therapy

    Comparison between sensory detection threshold (mA) at baseline and sensory detection threshold (mA) after one month of abortive therapy with Rimegepant 75 mg

    Measured: one month after the start of therapy
