NCT07731230

Brief Summary

This study tested whether a skin patch, worn behind the ear, could help reduce tinnitus (ringing or buzzing in the ears) in adults. Eighty participants took part. Half wore an active patch, and half wore a patch that looked the same but had no active effect (a placebo). Neither the participants nor the researchers knew who received which patch until the study ended. All participants also received an educational counseling session about tinnitus and how to manage it. Participants were assessed before treatment, three weeks later, about seven weeks later, and again about one year later. The researchers measured how much tinnitus affected their daily life, their sensitivity to sound, and their anxiety or mood.

Outcome Measures

Primary Outcomes (1)

  • Change in Tinnitus Handicap Inventory (THI) Score from Baseline to Day 51

    THI is a 25-item questionnaire (score range 0-100), with higher scores indicating greater tinnitus-related handicap.

    Baseline and Day 51 (21 days post-treatment + 30 days)

Secondary Outcomes (4)

  • Change in THI Score from Baseline to Day 21

    Baseline and Day 21

  • Change in THI Score from Baseline to 1 Year

    Baseline and approximately 1 year

  • Change in Hyperacusis Questionnaire (HQ) Score

    Baseline, Day 21, Day 51, and 1 year

  • Change in Hospital Anxiety and Depression Scale (HADS) Score

    Baseline, Day 21, and Day 51

Study Arms (2)

Biomodulator Patch

EXPERIMENTAL

Participants applied an active steady-state coherent biomodulator patch (Antinitus, Sensori AB, Sweden) behind the ear daily for three weeks. All participants in this arm also received a standardized one-hour informative counseling session at study entry, covering the auditory system, tinnitus, and management strategies

Device: Steady-State Coherent Biomodulator Patch (Antinitus)

Placebo Patch

PLACEBO COMPARATOR

Participants applied a placebo patch, visually indistinguishable from the active patch, behind the ear daily for three weeks. All participants in this arm also received the same standardized one-hour informative counseling session at study entry as the experimental group

Device: Placebo Patch

Interventions

A passive, light photon-driven biomodulator patch applied behind the ear and replaced daily for three weeks, intended to influence auditory neural activity through effects on tissue water coherency.

Biomodulator Patch

A patch visually indistinguishable from the active biomodulator patch but without active photon-driven effect, applied behind the ear and replaced daily for three weeks

Placebo Patch

PARTICIPANT, CARE PROVIDER, INVESTIGATOR, OUTCOMES ASSESSOR
Masking Details
Active and placebo patches were sealed in identical, indistinguishable envelopes by a third party, who recorded the allocation key separately. The investigator, who also served as the care provider and outcomes assessor (delivering counseling, dispensing patches, and administering weekly questionnaires), remained unaware of group allocation until the study concluded.

Intervention Model
PARALLEL
Model Details: Participants were randomly assigned in a 1:1 ratio to one of two parallel groups: an experimental group receiving the active biomodulator patch (Antinitus) or a control group receiving a visually identical placebo patch. Both groups applied their assigned patch behind the ear daily for three weeks and received the same standardized informative counseling session at study entry. Group allocation remained blinded to both participants and investigators throughout the study
