Effect of Highly Bioavailable Curcumin on Subjective Tinnitus

April 18, 2023 updated by: Ascension South East Michigan
This study will assess the effectiveness of highly bioavailable curcumin in suppressing subjective tinnitus based on pre- and post-treatment evaluations using the validated Tinnitus Functional Index (TFI) and Tinnitus Handicap Inventory (THI) surveys.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects with severe, subjective tinnitus due to sensorineural hearing loss will complete both TFI and THI surveys prior to starting therapy. Subjects will then be randomized to a treatment or placebo group. The treatment group will be provided with a supply of capsules containing 500 mg of curcumin-phosphatidylcholine combined with 250 mg of boswellia-phosphatidylcholine, which increases curcumin bioavailability. Subjects in the treatment arm will be instructed to take 1 capsule by mouth twice daily for 30 days. Placebo group subjects will be provided with a placebo compound with instructions to take the same number of capsules by mouth for the same period of time. Both the active compound and the placebo will be provided by Smartceuticals, Inc (910 W. Van Buren St. Ste 100-376 Chicago, IL 60607) to the outpatient pharmacy at Ascension Providence Park (Novi, MI), which will be responsible for storage, distribution and tracking. After 30 days, patients will be asked to return bottles to the pharmacy with any unused capsules to confirm and monitor compliance. Placebo and active agent capsules and bottles will be identical in appearance with the exception of a unique alphanumeric code on the bottle label that identifies whether the distributed capsules contain active agent or placebo. This code will be matched to the participating subject by the pharmacy and will be used at the end of the study to determine which treatment arm each subject was in. To facilitate blinding, the master list of alphanumeric codes will be maintained by the manufacturer. At the completion of therapy, subjects from both groups will re-take the TFI and THI.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Adults with subjective tinnitus due to sensorineural hearing loss as determined by routine audiogram.

Exclusion Criteria:

  • Adults with subjective tinnitus due to another cause
  • Sensitivity or allergy to test compounds
  • Use of other off-label medications, substances, treatments specifically for tinnitus mitigation (e.g., anti-depressant/anxiety medications, GABA-inhibitors, psychiatric-based interventions/counseling)
  • Pregnancy
  • Patients taking anticoagulants to minimize risk of drug-drug interactions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean change on the Tinnitus Functional Index (TFI)
Time Frame: Evaluate at the beginning of the trial and at the end of the 30 day treatment period.
Administer the TFI survey
Evaluate at the beginning of the trial and at the end of the 30 day treatment period.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
