42 patients. One injection each. 90% could hear again. The largest gene therapy trial for inherited deafness just published in Nature. Researchers delivered a working OTOF gene directly into the inner ear using an AAV vector. Average hearing went from 106 dB to 52 dB. Half the patients hit normal range. The youngest was under a year old. The oldest was 32, breaking the assumption this only works in developing ears. 2.5 years of follow-up. No retreatment. No dose-limiting toxicity. Cochlear implants route around the problem. This goes after the root cause.
