We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Can healthy volunteers participate?
Key exclusion criteria
1. Ossification or any other cochlear anomaly that might prevent complete insertion of
the electrode array or increased risk of infection (i.e. dysplastic cochlea), as
confirmed by medical examination and imaging including MRI

2. Current use of grommets or evidence of tympanic membrane perforation

3. Known allergic reaction to dexamethasone or similar medicine

4. Diagnosis of Auditory Neuropathy

5. Active middle ear infection or history of middle ear infection within past two years

6. Unrealistic expectations on the part of the subject regarding the possible benefits,
risks, and limitations that are inherent to the surgical procedure and use of the
prosthetic device

7. Unwillingness or inability of the candidate to comply with all investigational

8. Additional disabilities that would prevent or restrict participation in the
audiological and medical evaluations required of the clinical investigation

Brief summary
In an effort to further preserve residual acoustic hearing after cochlear implantation, it
may be beneficial to incorporate anti-inflammatory agents into the electrode array for
passive elution over a time course after implantation. This study aims to assess the ease and
effectiveness of such an electrode design, and to assess the preliminary safety of use of
such a device in the post-operative period. This study is a first-time-in-human study of the
investigational device.

In the first instance, the aim of the current investigation is to obtain first experience in
use of a Combined Device in the adult clinical population, and to assess tools and techniques
that may be considered in future clinical studies of similar devices.
