Chronic subjective tinnitus treated with home-use bimodal neuromodulation

Chronic subjective tinnitus has no cure and no single dominant standard of care; the FDA-created product code this domain centers on (QVN, 21 CFR 874.3410) exists because one company's De Novo grant defined an entirely new device category in 2023, three years before this file was built. Read the thinness up front: this dossier is strong on the founding device's own published pivotal-trial data (Section 5) and on the standard-of-care comparator literature (Section 4), because those are class-2 findings a literature connector reaches directly. It is weak-to-absent on US severity-stratified epidemiology (no NHANES-derived, severity-banded prevalence figure was located), on VA-specific figures (no connector in this repo reads VBA/VHA data, and the one primary VA document located could not be text-extracted in this environment — see Section 6 and Section 10), and on reimbursement (no HCPCS/payment/ coverage cache exists on this machine). A second candidate in this domain should expect to start from a well-populated Section 5 and a nearly empty Section 1 and Section 6.

This file carries no confidence tags. Every line below is context with a source attached. To affect a score, a line must be copied into a candidate's ## Claims as unverified and pass the Verifier or the Corroborator. See README.md in this directory.


1. Condition & epidemiology

as_of: 2026-08-27 · sources searched: connectors literature ("tinnitus prevalence United States adults", "chronic tinnitus prevalence severity United States NHANES"), literature-detail on PMID 27441392, WebSearch/WebFetch of the AAO-HNS guideline fact sheet · not searched: a severity-stratified (moderate-or-greater) prevalence estimate specific to the indicated population; incidence; demographic/geographic concentration; trend direction over time (a 2026 title, PMID 42089210, "Tinnitus Trends in Young Adults: Prevalence and Duration from 2008 to 2023," was located but not read past its title)

FactQuantity (n, population, date)Source
12-month tinnitus prevalence, general US adult population9.6% (SE 0.3%) — 21.4 (SE 3.4) million of an estimated 222.1 (SE 3.4) million US adults ≥18, 2007 National Health Interview Survey, raw n=75,764 respondents, published 2016[1]
Subjective severity among those with tinnitus7.2% rated it "a big or a very big problem"; 41.6% rated it "a small problem"; 31% "not bothered" (2007 NHIS cross-section)[1]
Duration / chronicity among those with tinnitus27% reported symptoms for longer than 15 years; 36% reported nearly-constant symptoms[1]
Alternative prevalence estimate (secondary/promotional, not independently retrieved as primary)"More than 50 million people in the United States have reported experiencing tinnitus, resulting in an estimated prevalence of 10% to 15% in adults"[15]

Verbatim, for anything load-bearing:

"Among an estimated (SE) 222.1 (3.4) million US adults, 21.4 (3.4) million (9.6% [0.3%]) experienced tinnitus in the past 12 months... In terms of subjective severity, 7.2% reported their tinnitus as a big or a very big problem compared with 41.6% who reported it as a small problem." — [1]

"Tinnitus affects up to 21% of the adult population with an estimated 1% to 3% experiencing severe problems." — [11] (Cochrane review background statement, itself citing other sources not independently traced here)

Gaps: No source located gives a severity-banded prevalence figure matching the candidate's actual indicated population ("moderate or greater severity," the validated-scale threshold the pivotal trials use — see Section 4/5 THI≥38 cutoff). [1]'s 7.2% "big or very big problem" figure is a self-report severity band from a different instrument (NHIS free-text severity, not THI/TFI) and should not be read as interchangeable with "moderate or greater" on a validated tinnitus-severity scale — that is an explicit gap, not a finding. This is a class-2 vs. proxy issue: the number exists, but it does not answer the population question the candidate's intended_use: poses. Not searched: any VA/veteran- specific chronic-tinnitus prevalence figure independent of the compensation-claims data in Section 6 (a compensation count is not a prevalence estimate, and Section 6 already carries that caveat).

2. Care pathway & clinical setting

as_of: 2026-08-27 — not researched this pass beyond what the guideline fact sheet and the candidate's own frontmatter establish.

Step in the pathwaySetting / site of serviceWho performs itWhat equipment is already thereSource
Initial evaluation, ruling out treatable/pulsatile causesAudiology or otolaryngology clinicAudiologist or physicianAudiometric booth, tympanometry[15] (guideline recommends against imaging for typical, non-pulsatile, non-asymmetric cases)
Device fitting (candidate's proposed model: remote)Predicate's model: in-clinic; candidate proposes remote fitting as its own product changeAudiologist/physician (predicate); remote per candidate's designFitting software, headphones, electrode componentCandidate frontmatter (mechanism:); not independently verified against the predicate's actual fitting protocol in this pass
Home daily treatmentPatient's homePatient, unsupervised between visitsHeadphones + electrical-stimulation unitCandidate frontmatter
Follow-up / outcome assessmentAudiology clinic (pivotal trials) or virtual visit (NCT05518682 protocol)AudiologistTHI/TFI questionnaires[16], [18]

Gaps: Not researched: staffing model and time-per-patient for fitting/follow-up, whether audiology clinics that dispense the predicate already have spare capacity or would need to add staff, and whether "remote fitting" as the candidate proposes has been done for any device in this classification (NCT05518682, [18], is a University of Minnesota protocol that explicitly tests self-adjustment via virtual visits, but it has posted no results — hasResults=false — so this is a registered intention, not a finding, on exactly the question the candidate's design rests on).

3. User groups & incentives

as_of: 2026-08-27 — not researched this pass; entries below are read off frontmatter and Section 5/6 findings, not independently sourced.

RoleWho they areWhat they gainWhat they lose / what it costs themWhose budgetSource
Prescriber / deciderLicensed audiologist or physician (per candidate intended_use:)A second device line to offer, per unverified deck assumptionTime to learn a new fitting workflowN/ACandidate frontmatter (not independently sourced here)
Operator / daily userPatientPotential symptom reduction (see Section 4/5 effect sizes)Daily adherence burden; no cure — tinnitus is not eliminated in any trial reviewedPatient (self-pay, per Section 6)[2], [3], [1]
PurchaserPatient, or VA formulary (channel-dependent)Device cost ($3,500-$4,750 self-pay range per secondary/blog sources, not independently confirmed against a primary price list — see Section 6)Patient out-of-pocket, or VA budget if VA-dispensedSecondary sources only, flagged as such in Section 6
PayerCommercial insurers reportedly do not cover Lenire (secondary-source claim, not independently verified)Not independently retrieved as primary; recorded as unconfirmed pending a payer policy document
PatientSame as operator above

Gaps: This section was not researched independently in this pass; every row rests on material already gathered for Sections 5/6 rather than a dedicated incentive-mapping exercise. Not searched at all: audiologist compensation/incentive structure for dispensing a device family, VA clinician workload/formulary-decision process.

4. Standard of care & clinical evidence

as_of: 2026-08-27 · sources searched: connectors literature on TRT/CBT/sound-therapy RCTs and Cochrane reviews, literature-detail on four PMIDs, WebSearch/WebFetch of the AAO-HNS 2014 guideline fact sheet · not searched: any post-2014 AAO-HNS guideline update (none was found to exist as of this search; not confirmed absent, just not located)

ItemWhat it establishesEvidence quality (design, n, endpoint)Source
Guideline position — hearing aids"Clinicians should recommend hearing aid testing for patients with hearing loss and persistent, bothersome tinnitus"AAO-HNSF 2014 multidisciplinary guideline, 13 recommendations[15]
Guideline position — CBT"Clinicians should recommend cognitive behavior therapy to patients with persistent, bothersome tinnitus"Same guideline[15]
Guideline position — sound therapy"Clinicians may offer sound therapy to patients with persistent, bothersome tinnitus" (weaker verb — "may offer," not "should recommend")Same guideline[15]
Guideline position — electrical/neuromodulation"Clinicians should NOT recommend transcranial magnetic stimulation for treating patients with persistent, bothersome tinnitus." No guideline statement located on bimodal acoustic-electrical neuromodulation specifically — the QVN classification postdates this 2014 guideline by nine yearsSame guideline; TMS is a different modality from the candidate's, noted for completeness, not read as directly on-point[15]
Pivotal trial(s) — predicate's own configuration (tongue stimulation)TENT-A2: RCT, n=326 adults with chronic subjective tinnitus, 3 arms, 12-week treatment + 12-month follow-up. THI Cohen's d -0.87 to -0.92 (P<.001); TFI -0.77 to -0.87 (P<.001). "High compliance and satisfaction rates with no treatment-related serious adverse events."Randomized, double-blinded, exploratory, industry-sponsored (Neuromod)[2]
Pivotal trial(s) — predicate, settings-optimization follow-onSecond large RCT testing whether background noise was necessary and whether re-adjusting settings at 6 weeks overcomes habituation. Cohen's d -0.7 to -1.4 across arms/measures over the full period. "High compliance rate (83.8%) with 70.3% of participants indicating benefit."Randomized, double-blinded[3]
Effect size vs. comparator — standard of care (TRT), independent of the predicateMulticenter phase 3 RCT, 151 active-duty/retired military and dependents, moderate-to-severe subjective tinnitus, TRT vs partial-TRT vs standard of care, 18-month follow-up. "There were few differences between treatment groups" on the primary Tinnitus Questionnaire endpoint; "About half of participants showed clinically meaningful reductions" — but this held across all three arms including standard of care, not preferentially for TRTRandomized, placebo-controlled, phase 3, NCT01177137, 6 US military hospitals[10]
Effect size vs. comparator — CBTCochrane review, 28 studies, n=2,733. CBT vs audiological care: THI mean difference -5.65 points (95% CI -9.79 to -1.50), moderate certainty, MCID=7 points — i.e. the pooled effect falls short of the study's own minimal-clinically-important-difference threshold. CBT vs no intervention: SMD -0.56, low certaintyCochrane systematic review/meta-analysis, GRADE-rated[11]
Effect size vs. comparator — sound therapy (hearing aids / sound generators)Cochrane review, 8 studies, n=590. "There is no evidence to support the superiority of sound therapy for tinnitus over waiting list control, placebo or education/information with no device." Quality of evidence "low" throughoutCochrane systematic review, GRADE-rated[12]
Known negative / equivocal findingsThe single largest, most rigorous RCT located for the standard-of-care comparator (TRT, [10]) found no meaningful separation from standard of care at 18 months; the Cochrane sound-therapy review ([12]) found no evidence of superiority over no treatment at allSee rows above[10], [12]

Verbatim:

"Longitudinal analyses showed no difference between partial TRT or TRT compared with SoC, or partial TRT compared with TRT, on TQ, TFI, or THI total scores... There were few differences between treatment groups." — [10]

"There is no evidence to support the superiority of sound therapy for tinnitus over waiting list control, placebo or education/information with no device... The quality of evidence for the reported outcomes, assessed using GRADE, was low." — [12]

Gaps: No head-to-head trial of bimodal acoustic-electrical neuromodulation against TRT, CBT, or sound therapy was located — [2] and [3] are single/parallel-arm comparisons of the predicate's own settings against each other, not against another standard-of-care modality. Read at abstract depth only; risk-of-bias tables, full CONSORT flow, and funding/COI disclosures were not read for any trial in this table. No post-2014 AAO-HNS guideline update was located (not confirmed to be absent — simply not found by this search).

5. Reference products — and why people stop using them

as_of: 2026-08-27 · sources searched: connectors literature/literature-detail, connectors trials/trial-detail, connectors clearances/recalls/classification, WebSearch/WebFetch of company and press materials · not searched: MAUDE adverse-event narratives specific to Lenire (no MAUDE connector run this pass), post-market surveillance reports, any formal withdrawal-reason table from the pivotal trials (none of the abstracts read report a per-arm dropout/attrition count — see gap below)

Lenire (Neuromod Devices Limited) — the QVN-founding device

SignalQuantity (n, population, date)Source
Discontinuation / dropout rate, pivotal RCT (TENT-A2)Not reported in the abstract read; "no treatment-related serious adverse events" and "high compliance and satisfaction rates" stated in aggregate, no per-arm attrition count given[2]
Discontinuation / dropout rate, settings RCTNot reported as a discontinuation figure; compliance reported as 83.8% (i.e. an adherence rate, not a dropout count) with 70.3% reporting benefit[3]
Discontinuation / dropout rate, real-world US retrospective chart review220 patients identified; 212 had available outcome data at ~12 weeks (8 of 220, 3.6%, had no outcome recorded — the paper does not state whether this is loss-to-follow-up/discontinuation or a data-completeness artifact; not the same claim as a discontinuation rate, flagged as a gap, not a finding)[1a]
Adherence over time83.8% compliance rate reported in [3]; no adherence curve over the full recommended treatment duration was located[3]
Stated reasons for discontinuationNot found. No trial or chart review read in this pass reports a withdrawal-reason table
Recurring complaint or failure modeNot found. No MAUDE search run this pass; no adverse-event narrative source retrieved
Recalls / enforcement0 records. recalls --product-code QVN --since 5y → 0; recalls --firm "Neuromod" --since 5y → 0. A Stage-0 scan result, carries no confidence tag — absence of a recall record is not the same as absence of a field-performance problemopenFDA recalls scan
Withdrawn from commercial distributionNot found; no indication located that Lenire has been withdrawn

"out of 212 patients with available data, there was a high responder rate of 91.5% (95% CI: 86.9%, 94.5%) with a mean improvement of 27.8 ± 1.3 (SEM) points, and no device-related serious adverse events." — [1a]

Gaps: The single most decision-relevant number this section is missing — a stated, per-arm discontinuation/dropout rate with reasons, of the kind docs/research-lane-spec.md §3.1 asks for — was not found in any of the three predicate-specific publications read at abstract depth. This may be a "not searched at full-text depth" problem rather than a "does not exist" problem: full-text methods/results sections (not retrieved in this pass) commonly report CONSORT flow diagrams with exact per-arm dropout counts that an abstract omits. Recorded as not found at abstract depth, not searched at full-text depth.

Tinnitus retraining therapy (TRT) — standard-of-care comparator

SignalQuantity (n, population, date)Source
Effect vs. standard of careNo statistically meaningful separation from standard of care at 18 months on the primary endpoint, across TRT, partial-TRT, and SoC arms alike[10]
Responder rate, TRT arm vs. others"About half of participants showed clinically meaningful reductions in the effect of tinnitus" — reported in aggregate, not broken out as a TRT-specific advantage over SoC[10]
Meta-analytic supportA 2021 meta-analysis of 13 RCTs (n=1,345) found TRT-plus-drugs outperformed drugs alone, but rated the underlying evidence "low-quality... with a high risk of bias"[13]

"Analysis of limited studies low-quality evidence with a high risk of bias showed that the TRT was an effective treatment for tinnitus... However, more multicenter RCTs with a large sample number and high quality should verify the conclusion." — [13]

Cognitive behavioral therapy (CBT) — standard-of-care comparator

SignalQuantity (n, population, date)Source
Effect vs. audiological careTHI mean difference -5.65 points (95% CI -9.79 to -1.50), moderate certainty — below the review's own 7-point MCID[11]
Trial attrition, internet-delivered CBT for acute tinnitus34.48% dropout attrition; 64.4% "training attrition" (non-usage) in the internet-delivered arm of a 337-participant RCT (87 in the internet-training condition)[14]

"There was a 34.48% dropout from the Internet-based training (dropout attrition). The training attrition from the Internet-based training was even higher at 64.4%." — [14]

Note this is acute tinnitus and an internet-delivery format, not the candidate's chronic/home-device population — carried here as the closest attrition figure located for a psychological-counseling comparator, with that scope difference flagged explicitly.

Hearing aids / sound generators — standard-of-care comparator

"There is no evidence to support the superiority of sound therapy for tinnitus over waiting list control, placebo or education/information with no device. There is insufficient evidence to support the superiority or inferiority of any of the sound therapy options... over each other." — [12]

No discontinuation-rate table was located within this review; "insufficient evidence" is the review's own limitation statement, not a dropout figure.

Section 5 overall gaps: No product in this section has a sourced, quantified discontinuation/dropout-with-reasons table at the standard this section's template asks for. The closest approaches are [14]'s attrition figures (wrong population/modality) and [1a]'s 212-of-220 completion figure (real-world, right device, but not stated by the authors as a discontinuation rate). This is the section's single biggest open item and the first place a Corroborator or a later Researcher pass should look at full-text depth.

ItemDetailSource
Codes in use (HCPCS; CPT only if licensed)None confirmed. hcpcs/payment/coverage connectors return unconfirmed for lack of a local CMS cache (data/hcpcs_level_ii.csv, data/hcpcs_payment_rates.csv, data/medicare_coverage_policies.csv all absent on this machine) — this is a missing-cache gap, not a confirmed absence of any codeConnector probes, this pass
Payment rate / fee scheduleNot established; no code confirmed to check a rate against
Coverage policy (NCD/LCD, commercial)Not established via connector. Secondary/consumer sources state Lenire is "not covered by insurance" and is self-pay — not independently verified against a payer policy document, recorded as an unconfirmed secondary claim, not a findingSecondary web sources only
Site-of-service differentialNot researched
Whose budget it comes out of — private channelPatient, self-pay (per unconfirmed secondary sources above)
Whose budget it comes out of — VA channelReported by the manufacturer to be available via a VA Federal Supply Schedule 65 II A Medical Equipment and Supply Contract to "Neuromod USA Inc.," effective per the press release 2024-06-17, also extending to DoD, Bureau of Prisons, Indian Health Services, Public Health Service[20], [21]
VA procurement mechanism, general (not Lenire-specific)The VA National Acquisition Center's Schedule 65 II A covers "worldwide distribution of hearing aids, hearing aid accessories, auditory implants, assistive devices, batteries... Telehealth messaging devices and peripherals." Contracts are "indefinite delivery/indefinite quantity type contracts awarded to pre-approved vendors using full and open competition," requiring "a proposal and undergo a thorough review process that considers ... commercial sales practices, capabilities, financials, and past performance."[19]
VA disability-compensation context (not a market-size or coverage figure)Company press materials state, citing "US VA Benefits Report Fiscal Year 2023": "More than 2.9 million veterans received more than $5 billion in compensation in 2023" for tinnitus and "Sixty-three percent of all auditory Veteran Compensation Claims were for tinnitus." This is sourced to a company press release quoting a federal document, not to the federal document's own text — see the attempted primary retrieval below[21]

Verbatim:

"Neuromod USA Inc. has been awarded a Federal Supply Schedule 65 II Medical Equipment and Supply Contract from the US Government" — [20], dated in the release to 2024-06-17

"Contracts are awarded to pre-approved vendors using full and open competition. To obtain a VA Schedule Contract a company must submit a proposal and undergo a thorough review process that considers factors including commercial sales practices, capabilities, financials, and past performance." — [19]

CPT descriptors are AMA-licensed and must not be reproduced here. No candidate HCPCS code was named or tested in this pass beyond exploratory probes on V5299/L8679, both of which returned unconfirmed for a missing cache, not for the code being wrong or right.

Gaps — primary-document attempt and its outcome, stated plainly: The VA Benefits Administration's own Annual Benefits Report (located at https://www.benefits.va.gov/REPORTS/abr/docs/2025-compensation.pdf, a real, retrievable federal PDF) was fetched, but this environment has no PDF text-extraction tool (pdftoppm/poppler-utils absent, pypdf/PyPDF2/fitz unusable) and the fetched document could not be read for its table content. This is "not retrieved," not "not found": the primary document exists and its URL is recorded, but its text was not confirmed to say what the press release says it says. The 2.9-million/63%/"#1 disability since 1955" figures therefore remain sourced only to a company press release quoting the report, not to the report's own text, and should not be treated as independently confirmed. Also not searched: the VA National Acquisition Center's contract-catalog tool for the actual FSS contract number, which would let a later pass confirm the contract's existence and terms independently of company messaging.

7. Technology trajectory

as_of: 2026-08-27 · sources searched: connectors clearances --product-code QVN (3y and 5y windows) · not searched: a longer historical view of tinnitus-device clearance activity generally (only the QVN-specific window was run), FDA guidance on tinnitus devices

Non-intraoral (auditory-somatosensory) bimodal research activity outside the predicateOngoing — NCT03621735 (completed, results posted, University of Michigan, trigeminal/somatosensory-adjacent, n=100), NCT07092033, NCT07158034, NCT06508060, NCT07393880 (various non-intraoral electrode/modality approaches, mostly academic-sponsored, mostly no results posted yet)Establishes that non-intraoral bimodal stimulation is an active academic research area, separate from the predicate's own intraoral configuration — directly relevant to the candidate's central technical risk (Claim 14 in idea-006)[16] and trial registry scan

Gaps: No count of tinnitus-device clearances outside QVN (e.g., under 874.3400 or 874.3300) over time was run, so "the clearance rate over time" for the broader category (rather than just QVN) is unestablished.

8. Market players & dynamics

Gaps: No funding-round, company-financial, or competitor-intent data was researched. This section should not be read as a market map — it is a byproduct of the regulatory and clinical-evidence searches above, not an independent market scan.

9. Open questions — and what would settle them

QuestionClass (1 registry / 2 published / 3 stakeholder-future)What would settle itReachable by?

Would VA audiologists prescribe a cheaper follower device over the incumbent Lenire?3 — stakeholder futureNot answerable. Revealed-behaviour twin: the incumbent's own real-world US chart-review outcome data ([1a]) and its documented VA/DoD Federal Supply Schedule contract terms are the closest observable analogue to "the VA channel accepted this device family at all" — researched above in Sections 5-6. What remains genuinely unanswerable is whether a second device would be added, which is the class-3 core of the question and is recorded, not answered, hereTwin researched; original left class 3
Would patients pay several thousand dollars out of pocket for a non-curative device when TRT/CBT/hearing aids (cheaper, often covered) show similarly modest effect sizes?3 — stakeholder future, with a revealed-behaviour twinNot answerable directly. Twin: what fraction of TRT/CBT/hearing-aid users discontinue those cheaper standard-of-care options, and why (Section 5) — researched above, and the honest finding is that none of the three standard-of-care abandonment tables were fully populated either (dropout figures found for CBT's internet-delivery format only, [14], in the wrong population)Twin partially researched; gap recorded
What does the CFR §874.3410 special-controls set (seven controls per idea-006's own Verifier note) require for clinical performance testing, and does it constrain the candidate's electrode-site change?1 — registry factconnectors regulation 874.3410 (already run by idea-006's own Verifier pass, per its Claims section)Yes, and already done at the candidate level — recorded here for domain reuse

What this dossier has never looked at: MAUDE adverse-event narratives for Lenire or any tinnitus device; any FDA guidance document on tinnitus devices (fda.gov intermittently gates automated requests, per this repo's standing caveat, and none was attempted here); CPT coding (licensed, out of scope by design); veterinary tinnitus data (does not apply — no US federal dataset exists for veterinary anything, noted for completeness); the VA's own contract-catalog system, as opposed to company press materials describing a VA contract; patent/FTO landscape for bimodal stimulation (out of scope for a domain dossier — this is a per-candidate FTO question, already flagged as idea-006's own most conspicuous gap in its Claims section, not duplicated here).
