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

Condition Intervention Phase
Age Related Macular Degeneration Drug: Ranibizumab 0.3 mg - 3 times monthly, then quarterly Drug: Ranibizumab 0.5 mg - 3 times monthly, then quarterly Drug: Ranibizumab 0.3 mg monthly Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-masked, Active-controlled, Multi-center Study Comparing the Efficacy and Safety of Ranibizumab Administered as Two Dosing Regimens in Patients With Subfoveal Choroidal Neovascularization Secondary to Age-related Macular Degeneration

Primary Outcome Measures:
  • Mean Change From Baseline in Best-corrected Visual Acuity of the Study Eye at Month 12 [ Time Frame: Baseline to 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.


Secondary Outcome Measures:
  • Mean Change From Baseline in the Total Lesion Area of the Study Eye at Month 12 [ Time Frame: Baseline to Month 12 ]
    Fluorescein angiography was conducted in conjunction with color fundus photography at screening and at Months 6 and 12. Investigators used digital fluorescein angiograms to determine presence or absence of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).

  • Mean Change From Baseline in Retinal Thickness at the Central Point of the Study Eye at Month 12 [ Time Frame: Baseline to Month 12 ]
    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.

  • Mean Change From Baseline in Retinal Thickness at the Central Subfield of the Study Eye at Month 12 [ Time Frame: Baseline to Month 12 ]
    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.

Arms Assigned Interventions
Experimental: Ranibizumab 0.3 mg - 3 times monthly, then quarterly Drug: Ranibizumab 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.
Experimental: Ranibizumab 0.5 mg - 3 times monthly, then quarterly Drug: Ranibizumab 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.
Active Comparator: Ranibizumab 0.3 mg monthly Drug: Ranibizumab 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.
