What this trial studies

This multicenter Phase 1/Phase 2 study evaluates the safety and efficacy of a single intravitreal dose of SAR402663 in adults with neovascular age-related macular degeneration. Participants will be enrolled in two parts: Part I focuses on dose escalation with multiple cohorts, while Part II involves randomization to one of two selected doses based on earlier results. Following treatment, participants will undergo regular assessments for 12 months, with an extended follow-up phase lasting up to five years to evaluate safety and clinical activity durability.

Who should consider this trial

Good fit: Ideal candidates are adults aged 50 to 90 with a diagnosis of macular neovascularization secondary to age-related macular degeneration who are currently receiving anti-VEGF treatment.

Not a fit: Patients with conditions that may prevent visual acuity improvement or those with a history of active ocular infections or uncontrolled glaucoma may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve vision and quality of life for patients suffering from neovascular age-related macular degeneration.

How similar studies have performed: Other studies have shown promise with similar approaches in treating neovascular age-related macular degeneration, but this specific treatment is being evaluated for the first time.
