Brief Summary
Many people with migraine also experience tinnitus - a persistent ringing, buzzing, or hissing in the ears - and research suggests these conditions share underlying biological mechanisms, including a protein called calcitonin gene-related peptide (CGRP) that is active in both the brain and the inner ear. COMPACT-PM is a randomized trial comparing two classes of migraine preventive medications in adults with bothersome tinnitus and a history of migraine: anti-CGRP therapies (newer injectable or oral agents that block CGRP or its receptor) versus conventional migraine preventives (antidepressants including amitriptyline, nortriptyline, and venlafaxine; antihypertensives including propranolol, verapamil, and candesartan; and the anticonvulsant topiramate). Participants are randomly assigned - like a coin flip - to one of the two treatment groups; neither group receives a placebo, as both receive active migraine treatment. The study's primary outcome is change in the Tinnitus Functional Index (TFI) over 24 weeks, with additional measures including hearing tests, balance assessments, auditory brainstem response testing, and a comprehensive symptom diary. The study is conducted at the Stanford Ear Institute and is funded by a philanthropic gift to the Department of Otolaryngology - Head \& Neck Surgery at Stanford University.

Outcome Measures
Primary Outcomes (1)
Change in Tinnitus Functional Index (TFI) Score
The TFI is a validated 25-item self-report questionnaire measuring the negative impact of tinnitus on daily life. Scores range from 0-100; higher scores indicate greater tinnitus burden. The minimally important clinical difference is 13 points. The primary endpoint is the between-arm difference in TFI change from baseline to 24 weeks. The Tinnitus Functional Index (TFI) is a validated 25-item self-report questionnaire measuring the negative impact of tinnitus on daily life. Scores range from 0-100; higher scores indicate greater tinnitus burden. The minimally important clinical difference is 13 points. The primary endpoint is the between-arm difference in TFI change from baseline to 24 weeks, with a greater reduction indicating better outcome.

Study Arms (2)
CGRP-Targeting Therapy
EXPERIMENTALParticipants assigned to this arm receive one CGRP-targeting migraine preventive agent selected by the treating clinician based on clinical appropriateness and patient factors. Options include anti-CGRP monoclonal antibodies (galcanezumab, erenumab, fremanezumab, eptinezumab) or gepants (atogepant, rimegepant). Treatment duration is 24 weeks.
Conventional Migraine Preventive Therapy
ACTIVE COMPARATORParticipants assigned to this arm receive one conventional migraine preventive agent selected by the treating clinician based on clinical appropriateness and patient factors. Options are organized by class: antidepressants (amitriptyline, nortriptyline, venlafaxine), antihypertensives (propranolol, verapamil, candesartan), or anticonvulsants (topiramate). Treatment duration is 24 weeks.

Eligibility Criteria
You may qualify if:
- Age 18 years or older
- Non-pulsatile, subjective tinnitus present for at least 6 months
- Tinnitus Functional Index (TFI) score greater than 25 at screening, indicating at least mild-to-moderate tinnitus burden
- Current or past history of migraine, vestibular migraine, or episodic headache disorder, diagnosed by a physician or meeting ICHD-3 criteria
- Clinically appropriate candidate for migraine preventive therapy as determined by the treating clinician
- Stable medication regimen for at least 3 months prior to enrollment (no new medications started or stopped within 3 months of screening)
- Ability to provide written informed consent
- Ability to complete self-report questionnaires in English or with certified interpreter assistance
- Willingness to attend three in-person study visits over 24 weeks and complete daily symptom diaries
You may not qualify if:
- Pulsatile tinnitus or objective tinnitus (tinnitus audible to examiner)
- Pregnancy, planned pregnancy during the study period, or breastfeeding
- Participation in any other interventional tinnitus treatment research protocol during the study period
- Currently receiving a CGRP-targeting medication (for participants being considered for the conventional arm) or a conventional migraine preventive medication listed in this protocol (for participants being considered for the CGRP arm) - to avoid within-arm ineligibility at randomization
- Known contraindication to all medications within the assigned study arm
- History of serious cardiovascular event (myocardial infarction, stroke, or unstable angina) within 6 months of enrollment
- Severe hepatic or renal impairment that would contraindicate study medications
- Active psychiatric disorder requiring medication adjustment within 3 months of enrollment
- Known hypersensitivity or prior serious adverse reaction to a medication within the assigned study arm
- Active malignancy or life expectancy less than 12 months
- Inability to complete study procedures or follow-up visits in the judgment of the investigator
