About this study
Official title: A Real-world Study on the Use of CGRP-targeted Medications for the Treatment of Vestibular Migraine in Chinese Patients
Vestibular migraine is a phenotype of migraine, characterized by more prominent vertigo symptoms compared to headache. Treatments for VM are mainly divided into two categories: acute treatment and preventive treatment. Acute treatment aims to reduce the severity and duration of a single episode, while preventive treatment aims to decrease the frequency, severity, and duration of attacks. Current acute treatments are primarily divided into pain relief and anti-dizziness, with specific drugs such as triptans and ergots being applicable for pain relief, but only betahistine has weak evidence for anti-dizziness, and relevant clinical evidence is very scarce. Preventive treatment mainly refers to migraine preventive treatments, with recommended medications including traditional drugs like topiramate, flunarizine, propranolol, etc., but the efficacy and safety of these drugs are limited. CGRP-targeted drugs are believed to play a role in the preventive treatment of VM, and there are related literature reports, but most are small-sample studies or retrospective studies. This study aims to explore the real-world efficacy of CGRP-targeted drugs in the acute and preventive treatment of VM through a prospective real-world study.

| Study group | Role | What they receive |
|---|---|---|
| A1 | Group A is the acute treatment group, which will observe the effectiveness of medication used for acute treatment after a VM (Vestibular Migraine) attack in the participants. Subgroup A1 will include participants who undergo acute treatment with CGRP-targeted drugs. Receives: Drug: CGRP R Inhibitor; CGRP Inhibitor | |
| A2 | Group A is the acute treatment group, which will observe the effectiveness of medication used for acute treatment after a VM (Vestibular Migraine) attack in the participants. Subgroup A2 will include participants who undergo acute treatment with medications other than CGRP drugs (such as NSAIDs, triptans, etc.). Receives: Drug: none-CGRP | |
| B1 | Group B is the preventive treatment group, which will observe the efficacy of 12-week prophylactic medication in participants. Subgroup B1: Patients receiving CGRP-targeted drugs (e.g., CGRP monoclonal antibodies or gepants) for preventive treatment. Receives: Drug: CGRP R Inhibitor; CGRP Inhibitor | |
| B2 | Group B is the preventive treatment group, which will observe the efficacy of 12-week prophylactic medication in participants. Subgroup B2: Patients receiving non-CGRP preventive medications (e.g., flunarizine, topiramate, propranolol, etc.). Receives: Drug: none-CGRP |
What is being measured
The primary outcome is the main question the study is designed to answer.
The average scores of the most severe vestibular symptom post-dose measured by VAS scale to evaluate the effectiveness of CGRP medication in the acute treatment of vestibular migraine
Vestibular symptom severity post-dose will be measured on Visual Analogue Scale (VAS) (0=No vestibular symptom, 10=worst vestibular symptom).
Measured: within 48 hours post-dose of CGRP medication
Change in number of Moderate/Severe vestibular symptom days as defined by Bárány Society for participants measured daily from the observational phase compared to baseline between group B1 and B2
After the start of treatment, participants are required to keep a daily dizziness diary. The definition of moderate and severe vestibular symptoms refers to the Barany Society. Symptoms that have an impact on daily activities but can still be endured are defined as moderate, while symptoms that completely prevent daily activities from being carried out are defined as severe.
Measured: 12 weeks after treatment
Secondary outcomes (1)
The percentage of patients satisfied with medication to evaluate the effectiveness of different treatment in the treatment of VM
Satisfaction with medication will be measured via 7-point SM scale
Measured: Within 48 hours post-dose of medication for group A1 and A2, 12-weeks after treatment for group B1 and B2
