1. BACKGROUND

This Statistical Analysis Plan (SAP) documents the statistical methods for summarizing and analyzing the efficacy and safety data from study BP29647. The main purpose of this SAP is to describe the data handling rules, derivation rules, and statistical analysis methods.

2. STUDY DESIGN

This is a multiple-center, multiple-dose and regimen, randomized, active comparator controlled, double-masked, five parallel groups, 36-week study in patients with subfoveal CNV secondary to AMD. The study design is shown in Figure 1 Study Design.

The five groups of this study are as follows.

• Arm A: 0.5 mg ranibizumab IVT every 4 weeks for 32 weeks (9 injections)

• Arm B: 1.5 mg R068674611VT every 4 weeks for 32 weeks (9 injections)

• Arm C: 6 mg R06867461 IVT every 4 weeks for 32 weeks (9 injections)

• Arm 0: 6 mg R06867461 IVT every 4 weeks up to Week 12 (4 injections), followed by 6 mg R06867461 IVT every 8 weeks (i.e., on Weeks 20 and 28; 2 injections)

• Arm E: 0.5 mg ranibizumab lVT every 4 weeks up to Week 8 (3 injections), followed by 6 mg R06867461 IVT every 4 weeks (6 injections)

These treatment arms have been chosen to compare the treatments in a treatment-na"ive population and in an anti-VEGF- incomplete-responder population. For the treatment-na"ive population the arms Band C will be compared with the reference arm A. For the anti-VEGF incomplete responder population, a subgroup of arm E will be compared to a similar subgroup of arm A.
