Purpose of review To discuss antisense oligonucleotide (ASON) therapy for autosomal dominant retinitis pigmentosa (adRP) caused by the proline-23-histidine (P23H) mutation in the rhodopsin gene. Recent findings Viral and nonviral therapies to treat adRP are currently under investigation. A promising therapeutic option is a nonviral approach using ASONs. This form of genetic therapy has demonstrated a dose-dependent and highly selective reduction of P23H mutant rhodopsin mRNA in animal models, and it is currently being investigated as a human phase 1/2 clinical trial. Summary There are promising new therapies to treat adRP. ASON has shown encouraging results in animal models and has undergone a phase 1 clinical trial. ASON does not use a viral vector, is delivered with standard intravitreal injection, and its effects are reversible.
