In a groundbreaking global gene therapy trial, Opal Sandy from Oxfordshire has become the first patient to receive this innovative treatment, showcasing remarkable results. Born deaf due to a rare genetic condition called auditory neuropathy, Opal's journey represents a pioneering leap forward in the field of audiology.

The condition, caused by a disruption of nerve impulses from the inner ear to the brain, left Opal without the ability to hear. However, within four weeks of receiving a gene therapy infusion to her right ear, astonishing progress was noted. Despite her cochlear implant in the left ear being switched off, Opal began to respond to sound, marking a significant breakthrough in her auditory capabilities.

Clinicians closely monitored Opal's progress and observed continuous improvement in her hearing abilities in the ensuing weeks. At the 24-week mark, her treated ear exhibited hearing levels close to normal for soft sounds, a development that left both her medical team and family astounded.

Opal's mother, Jo Sandy, expressed her joy, describing the moment when Opal first responded to their voices as "mind-blowing." The confirmation of near-normal hearing levels further fueled excitement among the clinical team, underscoring the unprecedented success of the gene therapy intervention.

The trial, known as CHORD, initiated in May 2023, seeks to explore the efficacy of gene therapy in restoring hearing for children affected by auditory neuropathy. Spearheaded by Professor Manohar Bance, an ear surgeon at Cambridge University Hospitals NHS Foundation Trust, the trial represents a significant step forward in the quest for alternative treatments for genetic-related hearing loss.

Professor Bance emphasized the critical window for intervention in children with auditory neuropathy, stressing the importance of early detection to prevent delays in speech development. He hailed the trial's outcomes as a potential game-changer in the landscape of auditory healthcare, offering hope to countless individuals affected by genetic hearing conditions.

The innovative gene therapy approach involves the infusion of a harmless virus carrying a functional copy of the OTOF gene, crucial for inner ear function, directly into the cochlea during surgery. Opal's participation in the trial not only transformed her life but also paved the way for future advancements in genomic medicine, providing hope to families worldwide grappling with similar challenges.

Opal's father, James Sandy, expressed pride in contributing to the trial's pivotal findings, envisioning a brighter future for children like Opal and their families. The results of Opal's 24-week assessment, along with other scientific data from the CHORD trial, are set to be presented at the American Society of Gene and Cell Therapy conference, offering further validation of this groundbreaking approach.

Dr. Richard Brown, Consultant Paediatrician at CUH and Investigator on the CHORD trial, highlighted the potential of such treatments to revolutionize patient care globally. With promising results and minimal adverse reactions observed thus far, the prospect of gene therapy as a viable alternative for genetic-related hearing loss holds immense promise for the future of audiology.
