Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Psychological and behavioral interventions, such as Cognitive Behavioral Treatment (CBT) and Tinnitus Retraining Therapy (TRT), are commonly applied either alone or in combination for the management of tinnitus but selection of the intervention model remains arbitrary. Our purpose is to evaluate the hypothesis that genetic markers may guide the choice of tinnitus treatment towards improved therapeutic outcomes. Patients with subjective idiopathic tinnitus are assigned to either a genetically-informed CBT or TRT intervention protocol based on the status of four single nucleotide polymorphisms (SNPs) of the dopamine and serotonin pathways, namely COMT rs4680, HTR2A rs7997012, HTR2A rs6311, and TPH2 rs4570625, that have been associated with behavioral or cognitive responses (Group A), or to a conventional approach (Group B) in which the choice of treatment was not directed by genotypic data. Tinnitus Handicap Index (THI) scores of perceived tinnitus severity are recorded at the initial and at the fourth session of treatment using appropriate questionnaires.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

group A genetically informed intervention

Group A patients are offered a genetically based approach to tinnitus management that includes a genetic test and at least three office based treatment sessions. A rationally-designed personalized management plan based on the genetic results is based on four single nucleotide polymorphisms (SNPs) of the dopamine and serotonin pathways, namely COMT rs4680, HTR2A rs7997012, HTR2A rs6311, and TPH2 rs4570625, that have been associated with behavioral or cognitive responses

Group Type EXPERIMENTAL

Cognitive Behavioral Treatment (CBT) and Tinnitus Retraining Therapy (TRT)

Intervention Type BEHAVIORAL

CBT is a psychologically informed treatment. Depending on individual patient needs, relevant areas of tinnitus education and management/self-management strategies, such as managing the emotional consequences of tinnitus, rapid relaxation, managing fear and avoidance behaviors and changing unhelpful thoughts and beliefs, are applied in accordance to a published manual \[10\].

TRT is based on the neurophysiological model focusing more on education and sound therapy than on analytical cognitive and behavioral interventions. A TRT program is usually included in a management scheme with hearing aids.

group B control

In Group B, treatments are offered randomly taking care to offer CBT to equal number of patients as in Group A. In both groups, during the first visit, patients are offered a simple, few-minute tinnitus update and advice, relevant to their educational level and are being suggested that an average of 4 sessions are required over a period of approx. 4 months for making tinnitus noise less or not bothersome

Group Type OTHER

Depending on individual patient needs, relevant areas of tinnitus education and management/self-management strategies, such as managing the emotional consequences of tinnitus, rapid relaxation, managing fear and avoidance behaviors and changing unhelpful thoughts and beliefs, are applied in accordance to a published manual \[10\].

TRT is based on the neurophysiological model focusing more on education and sound therapy than on analytical cognitive and behavioral interventions. A TRT program is usually included in a management scheme with hearing aids.
