Objective:

To evaluate the efficacy and safety of ixoberogene soroparvovec (ixo-vec) in treating neovascular age-related macular degeneration (nAMD) through sustained aflibercept expression after a single injection, which may significantly reduce treatment burden.

Key Findings:

• Persistent aflibercept expression was detected 4 to 5 years post-treatment in the OPTIC trial.
• Patients averaged fewer than 2 injections annually after receiving ixo-vec, compared to approximately 10 prior to enrollment, indicating a significant reduction in treatment burden.
• Visual acuity and central subfield thickness remained stable, with reduced treatment burden observed in a population previously requiring high-frequency injections.

Interpretation:

The findings suggest that ixo-vec may provide a durable treatment option for nAMD, addressing the variability and high treatment burden associated with current anti-VEGF therapies, which often require frequent dosing.

Limitations:

• The studies primarily involved patients with high treatment burden, which may not represent all nAMD populations and could limit the generalizability of the findings.
• Long-term safety and efficacy data are still pending from ongoing phase 3 trials.

Conclusion:

Ixo-vec shows promise as a long-term solution for nAMD, with significant reductions in treatment frequency and stable visual outcomes, addressing a critical need in the management of this condition.
