Study summary

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.

Read the detailed description

The proposed study is a Phase I/IIa, randomized, open-label, multi-center, First In Human trial of an Advanced Therapy Investigational Medicinal Product (ATIMP) to investigate the safety of Rincell-1 as a treatment for neural hearing loss.

All participants will be recruited from adult patients who have been assessed as being eligible to receive a unilateral cochlear implant (CI) on the National Health Service at a UK CI Centre.

Trial participants will meet UK NICE criteria for cochlear implantation, and will be:

  • Cohort 1: Patients with hearing loss due to bilateral progressive presbycusis (aged-related hearing loss)
  • Cohort 2: Patients with postsynaptic Auditory Neuropathy Participants will be randomized (3:2), by cohort, to receive either Standard Care unilateral CI plus a single dose of Rincell-1 administered at the same time as CI surgery, or Standard Care unilateral CI alone. Each cohort will have up to a total of 10 participants: 6 in the CI+Rincell-1 arm, and 4 in the standard care CI arm. A total of up to 12 participants across the two cohorts will be dosed with Rincell-1.

Subjects will be followed up to 52 weeks post-implantation.

Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

MMSE and MoCA

Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

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
