About this study

Official title: A Pre-Marketing, Prospective, Single-Site, Open-Label, Within-Subject, Pilot, Interventional Study of Adult Cochlear Implant Speech Perception With the CP1150 Sound Processor Compared With the Next Generation of Signal Processing Technology

This clinical study aims to investigate speech performance in quiet with an OTE Sound Processor with modified firmware compared with the commercially available CP1150. The study also investigates CP1110 and CP1150 with Forward Focus.

Read the detailed description

This study will build on the evidence previously collected on OTE and BTE Sound Processors and will support the design goals for access to the same sound processing algorithms across future OTE and BTE variants, including evidence required on the automation of FF and future implant compatibility.

Being tested
CP1150 Sound Processor, CP1150 NF, CP1150 + FF, CP1110

Questions about this trial

What is this clinical trial studying?

A study testing CP1150 Sound Processor, CP1150 NF and CP1150 + FF in people with Hearing Impairment, Sensorineural, run by Cochlear at 1 site in Australia.

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 10 inclusion and 7 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 7 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 5 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Speech Perception in Quiet Using an CP1150 Sound Processor (time frame: One day (in booth testing)). 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 7 Feb 2025.
