Hearing Loss clinical trials at UC Health
3 in progress, 1 open to eligible people

  • Randomized Controlled Trial of Valganciclovir for Cytomegalovirus Infected Hearing Impaired Infants

    open to eligible people ages 1 month to 5 months

    The overall goal of this study is to determine the clinical benefit and safety of antiviral therapy for asymptomatic congenital cytomegalovirus (cCMV) infected hearing-impaired infants. We will conduct a multi-center double-blind randomized placebo-controlled trial to determine whether hearing-impaired infants with asymptomatic cCMV have better hearing and language outcomes if they receive valganciclovir antiviral treatment. We will also determine the safety of antiviral valganciclovir therapy for asymptomatic cCMV-infected hearing impaired infants. This study will be unique in that the cohort enrolled will only include hearing-impaired infants with asymptomatic cCMV. Primary Objective: To determine if treatment of cCMV-infected hearing impaired infants with isolated hearing loss with the antiviral drug valganciclovir reduces the maximum worsening in left or right ear hearing 8 months after randomization compared to untreated cCMV-infected hearing impaired infants. Main Secondary Objectives: 1. To determine if valganciclovir treatment improves the following outcomes when compared to the control group: 1. The risk of a clinically significant worsening of hearing defined by occurrence of cochlear implantation due to progressive hearing loss or a ≥ 10 dB (decibel) increase in the minimum response level (MRL) at two or more audiometric test frequencies (from among 1 kHz, 2 kHz, and 4kHz) in either the left or right ear or a ≥ 15 dB increase at any of these frequencies in either the left or right ear between baseline and 8 months post-randomization. 2. The MacArthur-Bates Communicative Development Inventory (CDI) percentile score for words produced at 22 months of age. 3. The change in the average MRL across the 2 and 4 kHz frequencies from baseline to 8 months post-randomization in the best-ear. 2. To evaluate safety measures based on all grade 3 or greater new adverse events designated by the NIAID Division of AIDS (DAIDS) toxicity tables.

  • A Comparison of User-adjusted and Audiologist-adjusted Hearing Amplification

    Sorry, not yet accepting patients

    Fifty adults with mild to moderately severe sensorineural hearing loss will be fit with hearing amplification using two adjustment techniques. For the "audiologist fitting" technique, a licensed audiologist will adjust the hearing device using the standard of care procedures which include adjustment and verification of output to match prescribed targets (NAL-NL2) and subsequent fine tuning to optimize adjustments based on participant feedback. The second technique is "user-adjustment" of the device consisting of adjustment to overall level, high-frequency boost, and low-frequency cut by the participant while listening to speech. A cross-over design will be used in which half the participants are initially fit using the audiologist technique and the other half are initially fit using the user self-adjustment technique. Following a seven-day field trial, participants will return to the lab and the aids will be reset use the other technique. Participants will be blinded to the condition. During each seven-day field trial, users will have access to a volume control, Following the end of the two trials, participants will return to the lab for outcome assessment.

  • Clinical Evaluation of the Cochlear Nucleus CI532 Cochlear Implant in Adults

    Sorry, in progress, not accepting new patients

    The purpose of this study is to gather long-term data on the FDA approved CI532 cochlear implant, and CP1000 (Nucleus 7) sound processor
