Brief summary

The study will test if the efficacy and safety of an alternative dosing regimen is as effective as monthly injections.

Interventions

DRUGRanibizumab 0.3 mg - 3 times monthly, then quarterly

Subjects received intravitreal injections (in the study eye) of ranibizumab 0.3 mg over a duration of 12 months. They were treated monthly for 3 consecutive months and then quarterly for the remainder of the study. On those months when ranibizumab was not administered, patients received a sham injection to preserve the masking of the treatment arms.

DRUGRanibizumab 0.5 mg - 3 times monthly, then quarterly

Subjects received intravitreal injections (in the study eye) of ranibizumab 0.5 mg over a duration of 12 months. They were treated monthly for 3 consecutive months and then quarterly for the remainder of the study. On those months when ranibizumab was not administered, patients received a sham injection to preserve the masking of the treatment arms.

DRUGRanibizumab 0.3 mg monthly

Subjects received monthly intravitreal injections (in the study eye) of ranibizumab 0.5 mg over a duration of 12 months. On those months when ranibizumab was not administered, patients received a sham injection to preserve the masking of the treatment arms.

Outcome results

Primary

Mean Change From Baseline in Best-corrected Visual Acuity of the Study Eye at Month 12

Visual acuity (VA) was assessed in both eyes at each study visit using best correction determined from protocol refraction. VA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at an initial testing distance of 4 meters.

Time frame: Baseline to Month 12

Population: Per-Protocol (PP) population includes a subset of patients from the Intent to Treat (ITT) population who completed Month 12/Visit 15, had an assessment of Best Corrected Visual Acuity in the study eye at Month 12/Visit 15 and did not have any major study protocol deviations.

Optical Coherence Tomography (OCT) was performed on both eyes at screening and monthly from baseline through Month 12 prior to study drug administration. OCT images were evaluated at the central reading center (CRC) by trained graders and ophthalmologists experienced in clinical trials.

Time frame: Baseline to Month 12

Population: Intent to Treat (ITT) population, with use of Last Observation Carried Forward (LOCF), consisted of all patients randomized into the study. Patients were analyzed according to the treatment group to which they were randomized. Only patients with available data at baseline and Month 12 were included in the analysis.
