About this trial

Rinri Therapeutics is conducting a clinical trial of a new cell therapy called Rincell-1. Rincell-1 is being developed to treat adults with neural hearing loss, either age related hearing loss or auditory neuropathy, who also meet criteria for a cochlear implant. The goals of this study are:

* To learn about the safety profile of Rincell-1, the procedure used to inject it and the medications given to promote the growth of the cells * To evaluate how well Rincell-1 works by measuring changes in the function of auditory neurons. * To understand if Rincell-1 can be easily and successfully given at the same time as cochlear implant surgery

Participants will be randomly assigned to one of two groups: one group that receives a standard care cochlear implant, and the other that will receive an injection of Rincell-1 at the same time as their standard care cochlear implant. Researchers will compare the safety of Rincell-1 in combination with a cochlear implant to a cochlear implant on its own.

Participants will take part in the trial for 52 weeks after CI surgery. During that time, they will have regular follow-ups and will take daily measurements at home of their hearing health.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Hearing Loss due to bilateral progressive presbycusis

Approved for unilateral cochlear implantation as per UK NICE criteria (TA566)

Trial outcomes

Primary outcomes

1

Frequency and severity of AEs

Frequency and severity of AEs considered related to Rincell-1 alone, the procedure used to administer Rincell-1, and to the CI device and/or the administered concomitant NIMP regime.

Time frame
From baseline (at screening) to 52 weeks post-implantation

Secondary outcomes

1

Changes in mean ECAP thresholds

Change from baseline to primary evaluation timepoint in mean ECAP threshold, measured at each electrode for each participant

Time frame
From post-implantation baseline to 40 weeks post-implantation
2

Feasibility of administration of Rincell-1

Evaluated in terms of: * On-time delivery to theatre of the DP * Successful in-theatre DP preparation * Injection of the full DP into the target anatomical structure * DP sterility and viability

Time frame
At time of administration
