Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 year to 18 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Study population: Children with bilateral severe to profound sensorineural hearing loss who undergo implantation with the Nucleus Freedom Cochlear Implant System

Who may be able to join

  • 1 year to 17 years, 11 months of age.
  • Bilateral severe to profound sensorineural hearing loss for those 1 to 2 years of age. Severe hearing loss for those 2 years of age and older.
  • Limited benefit from bilateral hearing aids. Limited benefit is defined as a lack of progress in the development of simple auditory skills in conjunction with appropriate amplification and intensive aural rehabilitation over a 3 to 6 month period.
  • For younger children, unable to take speech perception tests due to age-related cognitive and linguistic limitations, limited benefit will be quantified using the Infant Toddler Meaningful Auditory Integration Scale (IT-MAIS)1 or Meaningful Auditory Integration Scale (MAIS)1.
  • For older children, capable of speech perception tasks, limited benefit is defined as £ 30% on the recorded open-set Multisyllabic Lexical Neighborhood Test (MLNT)2 or Lexical Neighborhood Test (LNT) 2, depending on the child's cognitive and linguistic skills.
  • English spoken as a primary language.
  • Willingness to participate in and to comply with all requirements of the protocol.

Who cannot join

  • Ossification or any other cochlear anomaly that might prevent complete insertion of the electrode array, as confirmed by medical examination and tests including MRI.
  • Signs of retrocochlear or central origin to hearing impairment as confirmed by medical examination and tests including MRI.
  • Medical or psychological conditions that would contraindicate undergoing surgery (e.g., active middle ear infections, tympanic membrane perforation).
  • Additional handicaps that would prevent or restrict participation in the evaluations.
  • Unrealistic expectations on the part of the subject or subject's parents/guardians, regarding the possible benefits, risks and limitations that are inherent to the surgical procedure and prosthetic device.
  • Unwillingness or inability of the candidate or candidate's parents/guardians to comply with all study requirements.

About this study

The objective of this multisite study is to evaluate the performance of the Nucleus Freedom cochlear implant system in a large population of sequentially implanted pediatric subjects.

Read the detailed description

The proposed study will include 50 pediatric subjects ages 1 year to 17 years, 11 months of age, implanted at up to 5 sites in the United States and Canada. The estimated duration of this multisite study is 18 to 24 months. The duration of individual subject participation is not to exceed 12 months.

The study will be conducted as a within-subject repeated measures experiment (in which each subject serves as his or her own control) in order to accommodate the heterogeneity that is well known to characterize hearing-impaired populations

Questions about this trial

What is this clinical trial studying?

An observational study of Sensorineural Hearing Loss, run by Cochlear.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

IT-MAIS (time frame: 12 Months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2014.
