Use of Modafinil in the Treatment of Tinnitus

Phase 1

Terminated

Brief Summary: A study on the effects of the FDA approved drug Modafinil upon attention problems associated with tinnitus. This is considered to be a safe drug with few side effects. Each subject will be asked to participate in 3 sessions each lasting approximately 1 hour in which cognitive testing and recordings will be taken. The study involves each subject taking a 2- week supply of Modafinil and a 2- week supply of placebo. We hypothesize inattention related to thalamocortical dysrhythmia found in tinnitus can be reduced by Modafinil thus improving vigilance.

Detailed Description: Modafinil, a drug primarily used in the treatment for narcolepsy, is also being using in treating attention problems found in Attention Deficit Hyperactive Disorder (ADHD). This study will investigate the efficacy of Modafinil upon attention deficits found in tinnitus patients by assessing pre-attentional and attentional processes (e.g., the amplitude of auditory evoked responses and simple reaction time).

Recruitment & Eligibility

Subjects should have tinnitus symptoms severe enough to seek medical attention.
Subjects will have been seen in the Hearing and Balance Center at University of Arkansas for Medical Sciences (UAMS).
Subjects will have had an audiogram.
Signed informed consent.
Women of childbearing potential must have a negative pregnancy test at screening and before being prescribed the study drug.

Exclusion Criteria

Disease-Specific Concerns

Subjects who have locally advanced breast cancer with skin ulceration will be excluded from this study due to the risk of worsening ulcers and healing difficulties
Stage IV breast cancer
Inflammatory breast cancer

General Medical Concerns

Subjects with Echo Cardiogram performance status 2, 3, and 4 are not eligible for this study
Allergy to any component of the treatment regimen
Women who are breast feeding
Pregnancy or refusal to use effective contraception while participating in this study
Inability to comply with study and/or follow-up procedures

History of myocardial infarction within 6 months
History of stroke within 6 months
Clinically significant peripheral vascular disease
Evidence of bleeding diathesis or coagulopathy
Presence of central nervous system or brain metastases
Major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to Day 0, anticipation of need for major surgical procedure during the course of the study
Minor surgical procedures such as fine needle aspirations or core biopsies within 7 days prior to Day 0
Pregnant (positive pregnancy test) or lactating
Urine protein: creatinine ratio >1.0 at screening
History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to Day 0
