Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Serious Adverse Events

    Assess the number of serious adverse events during the study, and compare between groups to indicate if there are more in the treatment group than the control group.

    6-weeks

Secondary Outcomes (4)

  • Number of Participants With Adverse Events

    6-weeks

  • Change in Minimum Masking Level (MML) in Units of dB (Decibels)

    6-weeks (pre-implant to after 6-weeks of VNS)

  • Percent Change in Tinnitus Handicap Inventory (THI)

    6-weeks (pre-implant to after 6-weeks of VNS)

  • Change in Tinnitus Handicap Questionnaire (THQ)

    6-weeks (pre-implant to after 6-weeks of VNS)

Other Outcomes (1)

  • Change in Tinnitus Functional Index (TFI)

    6-weeks (pre-implant to after 6-weeks of VNS)

Study Arms (2)

VNS Treatment

EXPERIMENTAL

Vagus nerve stimulation and tones are used 2.5 hours per day for a 6-week period.

Device: VNS Treatment

VNS Control

SHAM COMPARATOR

Vagus nerve stimulation and tones are given daily over a 2.5 hour period, but not in the same way as the experimental group, and in such a way that it is believed to be ineffective but still provide both VNS and tones so that blinding is maintained.

Device: VNS Control

Interventions

VNS is given in brief bursts over a 2.5 hour period. The subject also has headphone connected to a computer, and hears audio tones through the headphones that occur during VNS.

Also known as: VNS paired with tones, Serenity System
VNS Treatment

This is the sham-control group; subjects in this group will receive both tones and VNS, but in a manner that is expected to be ineffective.

Eligibility Criteria

Age22 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • to 65 years of age
  • Have been diagnosed as suffering from sensorineural tinnitus and at least some tonal quality of the tinnitus
  • Unilateral or bilateral tinnitus
  • Have experienced tinnitus for at least one year and failed at least one tinnitus therapy (such as a counseling or sound therapy procedure. The diagnosis of tinnitus will include an audiological or medical diagnosis in their health records, as well as a patient affirmation of tinnitus greater than 12 months
  • MML \>= 7 dB (decibel)
  • Have tinnitus score of 40 or greater on the Tinnitus Handicap Questionnaire; (THQ)
  • No tinnitus treatment for at least 4 weeks prior to study entry.
  • Willing and able to understand and comply with all study-related procedures during the course of the study

You may not qualify if:

  • Acute or intermittent tinnitus
  • Severe hearing loss in any ear, as defined as more than an 80 dB HL (decibels hearing level) at frequencies from 250 Hz. to 8,000 Hz.
  • Meniere's disease, ear tumors, or evidence of active middle ear disease (such as fluid, infection, tumor, mass)
  • Any other implanted device such as a pacemaker or other neurostimulator; any other investigational device or drug
  • Pregnant or plan on becoming pregnant or breastfeeding during the study period
  • Currently require, or likely to require, MRI or diathermy during the study duration
  • History of adverse reactions to anesthetics (e.g., lidocaine) that in the Investigator's opinion make surgery too risky
  • Beck Depression Inventory (BDI) of 30 or greater
  • Any other form of tinnitus treatments (e.g. Herbal medication, acupuncture or chiropractic medicine) are not allowed during the study.
  • Any drug known to mimic, increase or decrease release or removal of a diffuse neuromodulator, such as norepinephrine, dopamine, serotonin, benzodiazepines, and acetylcholine is not allowed, as well as any psychoactive medications.
  • Significant cardiac history
  • Use of any medication known to cause or increase tinnitus, such as NSAIDS (ibuprofen, naproxen, nabumetone, etc.), aspirin and other salicylates, furosemide (Lasix) and other "loop" diuretics, "mycin" antibiotics such as vancomycin, quinine and related drugs, and chemotherapy agents such as cisplatin.
  • Involvement in litigation (e.g., worker's compensation claim and/or receiving disability benefits related to tinnitus and/or hearing loss).
