Long Term Follow-up Study of AAVAnc80-hOTOF Gene Therapy

After completing one year of initial safety and efficacy assessments following an intracochlear administration of AAVAnc80-hOTOF in AK-OTOF-101, participants will continue to be observed for an additional approximately four years of safety and efficacy follow-up in this LTFU study, for a total of approximately five years of safety and efficacy observations after vector administration. For each participant, evaluations in the LTFU study will occur at approximately one and a half years and two years after vector administration, followed by annual visits through Year 5; the duration in this LTFU study is approximately four years, with the aim of understanding and mitigating any risks related to delayed adverse events, as well as characterizing the durability of effect of the AAVAnc80-hOTOF.
