Commitment afterwards
The first enquiry is estimated at five minutes. Participation would involve a 12-week course of trial tablets or placebo and clinical assessments in Japan. Ask the team about appointments, usual-care costs, the study protocol and consent before deciding.

Important to know. The study is in Toyama, Japan. Criteria describe outpatients in the published 20–80 age range with first-onset, persistent unilateral subjective tinnitus lasting 2–18 months, specified sensorineural hearing loss and symptom scores; further exclusions apply. The team must confirm the exact age boundary and language arrangements. NMN is investigational for tinnitus in this trial. Only the study team can assess eligibility and explain risks, costs and consent. An enquiry is not enrolment, and no personal benefit is promised. Tinnitus Action is independent and does not receive your enquiry or health information.

About this opportunity
Purpose
A university trial is testing NMN against placebo for a narrowly defined tinnitus group. Research participation can help determine effects and safety; efficacy is not established by its listing.

Pause for editorial review if recruitment closes, the study contact no longer accepts enquiries, or the participation route becomes unavailable.
