Fudan Tinnitus Doctor for Tinnitus Management

4. maj 2026 opdateret af: Eye & ENT Hospital of Fudan University

A Multi-agent Large Language Model Conversational AI for Tinnitus Management: The Fudan Tinnitus Doctor Randomized Controlled Trial

The goal of this clinical trial is to evaluate whether a conversational artificial intelligence-based digital intervention can improve symptoms in adults with chronic subjective tinnitus.

The main questions it aims to answer are:

Does the Fudan Tinnitus Doctor (FTD) system reduce tinnitus severity as measured by the Tinnitus Handicap Inventory (THI).

Does the FTD system improve sleep quality, anxiety, depression, and overall patient-reported outcomes.

Researchers will compare the FTD system to a non-conversational digital education program to determine whether the AI-based intervention provides greater clinical benefits.

Participants will:

Use either the FTD conversational AI system or a static digital education program for 30 days.

Complete standardized questionnaires assessing tinnitus severity, sleep, mood, and overall improvement at baseline, Day 14, and Day 30.

Engage with the digital platform for tinnitus self-management.

Studieoversigt

Detaljeret beskrivelse

This study is a prospective, two-arm, parallel-group, open-label randomized controlled trial designed to evaluate the efficacy, usability, and safety of a multi-agent large language model (LLM)-based conversational artificial intelligence system (Fudan Tinnitus Doctor, FTD) for the management of chronic subjective tinnitus.

A total of 256 participants will be randomized in a 1:1 ratio to either the FTD intervention or a non-conversational digital education control. The intervention period is 30 days. The FTD system delivers personalized, real-time tinnitus management using a multi-agent architecture integrating cognitive behavioral therapy (CBT)-based strategies, including psychoeducation, cognitive restructuring, relaxation training, and sleep hygiene guidance. The control group receives a static digital program consisting of educational materials and a fixed-response question-and-answer module.

The primary outcome will be the change in tinnitus severity measured by the Tinnitus Handicap Inventory (THI) from baseline to Day 30. Secondary outcomes will include sleep quality (Pittsburgh Sleep Quality Index, PSQI), anxiety (GAD-2), depression (PHQ-2), and overall perceived improvement (Patient Global Impression of Change, PGIC). Exploratory outcomes will assess usability (System Usability Scale, SUS), satisfaction (Net Promoter Score, NPS), and engagement metrics. All outcomes will be analyzed using mixed-effects models under the intention-to-treat principle.

Beskrivelse

Inclusion Criteria:

  1. Diagnosis of subjective tinnitus confirmed by a qualified investigator.
  2. Tinnitus duration ≥ 3 month prior to screening.
  3. THI score of ≥ 18
  4. Aged between 18 and 70 years
  5. The ability to use a smartphone: Both groups will receive therapeutic support and disease management primarily through a mobile application or web-based platform. This requires functional ability to operate the provided software and willingness to engage with the digital intervention protocol.
  6. Perceptibility: Tinnitus is present and recognizable by the participant under ordinary daily conditions (not only in quiet environments).
  7. Compliance and consent: Participant is assessed by the Investigator as able to understand study procedures, voluntarily agrees to participate, is willing to comply with all trial-related requirements, and provides signed informed consent prior to performance of any protocol-specified procedure.

Exclusion Criteria:

  1. Acute-phase tinnitus (duration < 3 month or tinnitus secondary to acute otologic events).
  2. Pulsatile or objective tinnitus.
  3. Unstable symptoms: Fluctuating tinnitus loudness at screening or baseline.
  4. Psychiatric contraindication: History or current presence of severe psychiatric disorders (e.g., major depressive disorder with recent suicidality, schizophrenia) that, in the opinion of the Investigator, may interfere with study participation or data validity.
  5. Testing limitations: Inability to adequately complete tinnitus testing procedures or comply with study assessments.
  6. Prior therapy exposure: Previous history of sound therapy specifically for tinnitus management.
  7. Concurrent treatments: Ongoing psychotherapy for conditions such as anxiety or depression, or any other psychological treatment that may interfere with the study endpoints.
  8. Concurrent trial participation: Active participation in another interventional research study that, in the opinion of the Investigator, could affect tinnitus symptoms or interact with study procedures.
  9. Investigator judgment: Any condition (medical, surgical, psychiatric, or social) or factor which, in the Investigator's judgment, renders the subject unsuitable for participation, places the patient at higher risk, or may interfere with compliance or scientific validity of the trial.

Foranstaltningsbeskrivelse
Tidsramme
Tinnitus Handicap Inventory (THI)
Tidsramme: Baseline, dag 14 og dag 30
THI-spørgeskemaet, som er bredt anvendt i forskning, inkluderer funktionelle, følelsesmæssige og katastrofale subskalaer. Det består af 25 spørgsmål, og svar vurderes på en skala med "ja" (4 point), "nogengange" (2 point) og "nej" (0 point). Den samlede score beregnes ved at lægge scorerne for alle spørgsmål sammen og klassificere tinnitusens sværhedsgrad som ingen handicap (0-16), let handicap (18-36), moderat handicap (38-56) og svær handicap (58-100).

Foranstaltningsbeskrivelse
Tidsramme
Patient Health Spørgeskema-2 (PHQ-2)
Tidsramme: Baseline, dag 14 og dag 30
PHQ-2 vil måle depressive symptomer over de sidste to uger. Hver af de to poster vurderes fra 0 ("slet ikke") til 3 ("næsten hver dag"). Den samlede score spænder fra 0 til 6, hvor højere score indikerer større depressive symptomer. En score ≥3 indikerer klinisk signifikant depression.
Baseline, dag 14 og dag 30
Patient Global Impression of Change (PGIC)
Tidsramme: Dag 14 og Dag 30
PGIC vil vurdere deltagerens overordnede opfattelse af forbedring siden starten af interventionen. Det vurderes på en 7-punkts Likert-skala fra 1 ("meget forbedret") til 7 ("meget forværret"), hvor lavere scorer repræsenterer større opfattet forbedring.
Dag 14 og Dag 30
Generalized Anxiety Disorder Scale (GAD-2)
Tidsramme: Baseline, Day 14, and Day 30]
The GAD-2 will assess anxiety symptoms over the past two weeks. Each of the two items is rated from 0 ("not at all") to 3 ("nearly every day"). The total score ranges from 0 to 6, with higher scores indicating greater anxiety. A score ≥3 suggests clinically significant anxiety.
Baseline, Day 14, and Day 30]
Pittsburgh Sleep Quality Index (PSQI)
Tidsramme: Baseline, Day 14, and Day 30
The PSQI will be used to evaluate subjective sleep quality over the past month. It comprises 19 items yielding seven component scores (subjective sleep quality, latency, duration, efficiency, disturbances, use of sleep medication, and daytime dysfunction). The global PSQI score ranges from 0 to 21, with higher scores indicating worse sleep quality.
