lunsotogene parvec · OTOF (AAV, intracochlear)
Efficacy evidence
Otof-Q828X homozygous deafness mouse: dose-dependent ABR threshold recovery with otoferlin expression in IHCs
“Nonclinical pharmacology studies were conducted in Otof-Q828X hom (homozygous) mice, a model of OTOF-related deafness that recapitulates the human phenotype with profound hearing loss and absent auditory brainstem responses (ABRs).”
Why that model
Otof-Q828X mouse recapitulates human OTOF deafness (profound hearing loss, absent ABRs)
“Nonclinical pharmacology studies were conducted in Otof-Q828X hom (homozygous) mice, a model of OTOF-related deafness that recapitulates the human phenotype with profound hearing loss and absent auditory brainstem responses (ABRs).”
Reviewer's view of the efficacy data
Supportive: sustained otoferlin expression and durable ABR improvement for at least 30 weeks support long-term benefit
“This study demonstrated that a single IC administration of DB-OTO resulted in sustained otoferlin protein expression in IHCs and durable ABR threshold improvements that were maintained for at least 30 weeks post-administration.”
