Brief Title
Cochlear Implant With Dexamethasone Eluting Electrode Array
Official Title
Cochlear Implant With Dexamethasone Eluting Electrode Array (The CI-DEX Study): Pivotal Study
Brief Summary
An evaluation of Cochlear's cochlear implant electrode array which passively elutes dexamethasone for a defined period of time to help reduce inflammatory responses.
Detailed Description
The primary objectives of the pivotal evaluation is to show the efficacy of the dexamethasone eluting electrode through reduction in electrode impedances as compared to a standard electrode and the improvement of speech recognition from preoperative baseline. The secondary objectives are to assess the benefit-risk balance of a dexamethasone eluting electrode as similar to a standard electrode by comparison of adverse events and speech outcomes.
Study Type
Interventional
Primary Outcome
Comparison of Monopolar (MP1+2) impedance measurement (kOhms) between randomisation groups measured through Custom Sound software during clinical visits.
Secondary Outcome
Comparison of rate and type of device related adverse events between randomisation groups.
Condition
Sensorineural Hearing Loss
Intervention
CI632D
Study Arms / Comparison Groups
