Cochlear Implant PDA Based Research Platform (ciPDA)

June 12, 2012 updated by: Philip Loizou

Multi Center Clinical Study to Assess the Safety of the UTD Cochlear Implant PDA (ciPDA) REsearch Platform

The primary purpose of the research is to study how individuals who wear cochlear implants process sounds in noisy environments and also whether newly designed programs can help improve the communicative ability of cochlear implant patients in noisy situations.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

Cochlear implants have been successful in restoring partial hearing to profoundly deaf people. Despite their success, most implant patients are not able to communicate in noisy environments (e.g., in a restaurant). Communicating in noise still remains one of the biggest challenges in cochlear implants. Little is known about the factors that contribute to the poor performance of CI users in noise. In this project, we propose a series of experiments aimed at isolating these factors. We propose new programs that can be tailored for noisy situations.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Post-lingually deafened adults:

    • 18 years of age or older
    • Unilateral or bilateral Nucleus implant users (this includes all three generations of the Nucleus system, i.e., CI22, CI24 and CI24R).
    • With or without residual hearing in the contralateral ear. Subjects may use amplification (hearing aid) in the opposite or same ear as the implant.
    • A minimum test score of 30% in tape-recorded open-set sentence recognition scores (e.g., spondee identification).
    • Minimum of 6 months experience with their implant device. This is done to ensure that all patients are familiar with the hearing sensations perceived by a cochlear implant.
    • Minimum number of active electrodes: 10
    • Minimum number of subjects for each test site: 5

  2. Prelingually and perilingually deafened adults:

    • 18 years of age or older
    • Unilateral or bilateral Nucleus implant users.
    • With or without residual hearing in the contralateral ear. Subjects may use amplification (hearing aid) in the opposite or same ear as the implant.
    • A minimum test score of 10% in tape-recorded open-set sentence recognition scores (e.g., spondee identification).
    • Minimum of 6 months experience with their implant device. This is done to ensure that all patients are familiar with the hearing sensations perceived by a cochlear implant.
    • Minimum number of active electrodes: 10
    • Minimum number of subjects for each test site: 5

Exclusion Criteria:

  • Non-English speaking
  • Hearing loss of neural or central origin
  • Absence of cochlear or VIII nerve development
  • The presence of systemic condition which would preclude use of a cochlear implant
  • Active middle ear infection/tympanic membrane perforation
  • Significantly abnormal cognitive function, as determined by case history information and/or clinical observations
  • Significant psychiatric disorder, as determined by case history information and/or clinical observations
