Brief summary
Ranibizumab is a humanised recombinant monoclonal antibody fragment targeted against human vascular endothelial growth factor A. This study will assess the safety and efficacy of ranibizumab administered on an as-needed dosing regimen in patients with subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).

Recruitment details
The study population consisted of two groups, one group being naïve to ranibizumab (Non-ANCHOR patients) and the other group were those patients who previously were treated with ranibizumab in the ANCHOR study (NCT00061594; ANCHOR patients).
Participants by arm
| Arm | Count |
|---|---|
| Ranibizumab Non-ANCHOR Patients received up to 12 intravitreal injections (Month 0 through Month 11). The dose of 0.3 mg ranibizumab was administered monthly for three consecutive months. From Month 3 through Month 11, either 0.3 mg ranibizumab or, after implementation of an amendment to the protocol, 0.5 mg ranibizumab were injected as individually needed based on retreatment criteria described in the protocol. Ranibizumab was administered no sooner than 14 days after the previous treatment. | 513 |
