Pioneers Recruitment Registry
Study objective: The goal of this study is to assess the safety and tolerability of an inner ear infusion of CGF166, a gene therapy. Another goal is to assess the effectiveness of CGF166 by measuring changes in hearing before and after treatment. Some of the possible benefits that researchers believe CGF166 may provide include improved hearing that may be revealed as improved speech recognition, and the ability to benefit from a hearing aid and avoid the need for a cochlear implant.
Am I eligible? Participants should be 21 to 70 years of age with severe hearing loss in both ears. You will be unable to participate if your hearing loss was caused by genetic/developmental disorders, surgery, or trauma. Also, participants will be excluded if they have cochlear implants, Meniere's disease, or immunodeficiency diseases.

The electrodes in a cochlear implant can be used to direct gene therapy and regrow neurons.
Researchers have demonstrated a new way to restore lost hearing: with a cochlear implant that helps the auditory nerve regenerate by delivering gene therapy.
The researchers behind the work are investigating whether electrode-triggered gene therapy could improve other machine-body connections—for example, the deep-brain stimulation probes that are used to treat Parkinson’s disease, or retinal prosthetics.
More than 300,000 people worldwide have cochlear implants. The devices are implanted in patients who are profoundly deaf, having lost most or all of the ear’s hair cells, which detect sound waves through mechanical vibrations, and convert those vibrations into electrical signals that are picked up by neurons in the auditory nerve and passed along to the brain. Cochlear implants use up to 22 platinum electrodes to stimulate the auditory nerve; the devices make a tremendous difference for people but they restore only a fraction of normal hearing.
“Cochlear implants are very effective for picking up speech, but they struggle to reproduce pitch, spectral range, and dynamics,” says Gary Housley, a neuroscientist at the University of New South Wales in Sydney, Australia, who led development of the new implant.
