SAR-402663

This is a Phase 1/Phase 2 multicenter study to evaluate the safety and efficacy of a one-time single-eye intravitreal dose of SAR402663 in participants with neovascular age-related macular degeneration.
Participants will be enrolled in one of 2 parts:
* In Part I (dose escalation), multiple dose levels of SAR402663 will be evaluated in successive cohorts of participants
* In Part II (dose expansion), participants will be randomized to receive one of two dose levels selected based on data from Part I. Participants and investigators will be masked to dose.
After receiving one-time dose of SAR402663, participants will undergo regular assessments over 12 months. Following this, participants will enter an extended follow-up (EFU) phase for the assessment of safety and durability of clinical activity of SAR402663 through Year 5.
