Figure Lengend Snippet: Intracochlear injection of SENS-501 in NHPs results in a mild humoral and an undetectable cellular response to the capsid (A) AAV8 anti-drug antibody (ADA) titers measured in serum at pre-dose and at 16, 29, and 92 days post-vector administration in NHPs. (B) Anti-AAV8 neutralizing antibodies (NAb) titers measured in serum at pre-dose and at 16, 29, and 92 days post-vector administration in NHPs. (C and D) IFN-γ spot forming units (SFUs) measured by ELISpot assay at 29 (C; left) and 92 (D; right) days post-injection. Peripheral blood mononuclear cells (PBMCs) from the indicated groups were stimulated with three different AAV8 peptide pools and a positive control (PMA/ionomycin). The dotted line represents the assay-specific positivity threshold. Each dot represents one animal. Bars represent the mean ± SEM.
