In collaboration with the NIHR Nottingham Hearing Biomedical Research Unit, a new trial into Tinnitus has opened at Nottingham University Hospitals.

AUT00063 (the study medicine) is an experimental new medicine for treating hearing disorders, such as loss of
hearing or tinnitus (a `ringing’ or buzzing noise in the ears). Hearing disorders are common in older people and have
recently become more common in young people. There are no licensed drugs available for hearing loss or tinnitus.
Reduced activity at certain sites in the brain (called “voltage-gated potassium channels”) has been linked to hearing
loss. The study medicine has been developed to treat the brain component of hearing disorders.
The main purpose of this study is to demonstrate a clinically relevant improvement in tinnitus severity after repeat
dosing of the study medicine or the placebo, in subjects with subjective tinnitus.
This will be determined by looking at a number of assessments (physical examinations, blood sampling, audiometric
assessments, questionnaires, etc.) done on patients experiencing noise or age-related tinnitus. Each patient will be
maximum 11 weeks in the study and will need to visit the clinic 5 times.

Gill suffers from tinnitus and is a Nottingham NIHR Hearing BRU trial participant. In this video, Gill describes her experiences of being part of a clinical trial with the Unit. Gill says: I became involved in the tinnitus trial because 23 years ago (when the tinnitus was diagnosed), the consultant I saw said “I don’t know much about tinnitus”. “We don’t really understand what it is all about”. And now, here and now, research is being done.” Continue reading

COCHLEAR IMPLANTATION IN PATIENTS WITH SINGLE-SIDED DEAFNESS
Individuals with severe/profound hearing loss in one ear experience great difficulty to understand speech in
background noise and to localize sounds. The “standard of care” is a specialized hearing aid called a “contralateral
routing of signals” (CROS) system, which picks up sound at the deaf ear and delivers it to the opposite ear. This
enables the user to hear sounds at the poor side, but does not allow spatial separation of sound sources as all
sounds are perceived in one ear. Consequently, benefits are limited and uptake of CROS systems is low.
A cochlear implant (CI) is a surgically implanted hearing aid, and an approved treatment for bilateral deafness. There have been some recent reports, from outside the UK, of successful CI use in patients with single-side deafness
(SSD), where a CI can restore some hearing in the deaf ear. The aim of the proposed pilot study is to measure
outcomes from a cohort of such patients in detail, and to compare them with outcomes using a CROS system. The
study is funded by an NIHR grant, by Nottingham University Hospitals NHS Trust, the MRC Institute of Hearing
Research and by industry support from Cochlear Europe Ltd.
Adults with SSD will be recruited at five UK CI centres. They will be fitted with modern CROS systems for a 3 month trial, and then be given the option to proceed to cochlear implantation. 10 participants will be implanted. Detailed measures of sound localization, speech understanding in noise and a range of self-report questionnaires will be administered before treatment (baseline), and at intervals during the CROS trial and the first 9 months post implantation in order to obtain performance and healthutility comparisons between CROS and CI systems, which will potentially inform future NHS funding.
· Eighteen years of age or older at the time of entry to the study.
· Able and willing to undertake all assessments required by the study.
· Good understanding of written and spoken English.
· Normal anatomy of the cochlea and auditory system on MRI scanning.
· Medical fitness to undergo general anaesthesia.
· Poorer ear (ear to be implanted): (i) Acquired (post-lingual) severe to profound sensorineural hearing loss of
greater than 6 months and 90dB HL at 1 & 4 kHz, and no better than 65 dB HL at 500 Hz, (ii) Minimal benefit from hearing aids defined as scoring
less than 50% on Bamford-Kowal-Bench (BKB) sentences presented at 70 dB SPL.
· Better ear (contralateral ear): Normal or near-normal hearing. For the purposes of this study this is defined as hearing thresholds with a puretone average (PTA) of 30 dB HL at 500, 1000, and 2000 Hz.
· Evidence of middle-ear pathology based on otologic examination and immitance testing (NB: it is possible that
some such cases might be resolvable by medical/surgical treatment, so that the subject may be eventually included).
· Medical or psychological conditions that contraindicate undergoing surgery.
· Tinnitus as primary motivation for treatment.
· Abnormal anatomy of the cochlea that might prevent complete insertion of the electrode array and abnormalities of the
· Hearing loss of neural or central origin, including auditory neuropathy and neurofibromatosis type II.
· Additional handicaps that would prevent or restrict participation in the audiological evaluations.
· Unrealistic expectations on the part of the subject regarding the possible benefits, risks, and limitations which are
inherent to the surgical procedure and prosthetic device.
· Any known factor which would limit the benefit obtainable from a cochlear implant device.
