Outcomes

Primary Outcome Measures

Percentage of Patients Who Gained ≥ 15 Letters in Their Best Corrected Visual Acuity (BCVA) Score From Baseline at Month 24

BCVA was measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity (VA) chart starting at a test distance of 4 meters. The BCVA score is the number of letters read correctly by the patient. An increase in the BCVA score indicates an improvement of vision.

Secondary Outcome Measures

Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) Score at Months 24, 36, and 48

Percentage of Patients With a Visual Acuity (VA) Snellen Equivalent of 20/40 or Better at Months 24, 36, and 48

VA was measured using the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart starting at a test distance of 4 meters. An increase in the number of lines read correctly by the patient in the ETDRS chart indicates an improvement of vision. The Snellen equivalent of 20/40 or better is 69 or more letters correctly read in the EDTRS chart.

Percentage of Patients Who Lost < 15 Letters in Their Best Corrected Visual Acuity (BCVA) Score From Baseline at Months 24, 36, and 48

Mean Change From Baseline in Best Corrected Visual Acuity (BCVA) Score at Months 24 and 36 in Patients With Focal Edema at Baseline

Mean Change From Baseline in Central Foveal Thickness at Months 24, 36, and 48

Central foveal thickness was assessed in optical coherence tomographic images by the central reading center. A decrease in foveal thickness suggests a reduction in macular edema. A negative change score indicates improvement.

Percentage of Patients With a ≥ 3-step Worsening From Baseline in the Early Treatment Diabetic Retinopathy Study (ETDRS) Diabetic Retinopathy Severity Scale Score for Eyes at Months 24 and 36

The severity of diabetic retinopathy was graded on a 10-point scale by the central reading center by comparing patient fundus photographic images with a set of standard images. 1=diabetic retinopathy (DR) severity level 10, 12 (DR absent), 2=DR severity level 14A-14C, 14Z, 15, 20 (DR questionable, microaneurysms only), 3=DR severity level 35A-35F (mild non-proliferative [NP]DR), 4=DR severity level 43A, 43B (moderate NPDR), 5=DR severity level 47A-47D (moderately severe NPDR), 6=DR severity level 53A-53E (severe NPDR), 7=DR severity level 60, 61A, 61B (mild proliferative [P]DR), 8=DR severity level 65A-65C (moderate PDR), 9=DR severity level 71A-71D (high-risk PDR), 10=DR severity level 90 (cannot grade). A lower score indicates less severe diabetic retinopathy.

Percentage of Patients With Resolution of Leakage at Month 24

Resolution of leakage was defined as total area of fluorescein leakage in the central, inner, and outer subfields of the 0 Disc Area. Leakage was assessed in fluorescein angiographic images by the central reading center.

Mean Number of Macular Laser Treatments From Baseline Through Months 24 and 36

The need for macular laser treatment was evaluated by the masked (evaluating) physician. Macular laser was administered per protocol-specified objective and subjective criteria starting at Month 3.

Percentage of Patients Who Gained ≥ 15 Letters in Their Best Corrected Visual Acuity (BCVA) Score From Baseline at Months 36 and 48

Mean Change From Month 36 in Best Corrected Visual Acuity (BCVA) Score in the Study Eye at Month 48

Percentage of Patients Who Lost < 15 Letters in Their Best Corrected Visual Acuity (BCVA) Score in the Study Eye From Month 36 at Month 48

Mean Change From Month 36 in Central Foveal Thickness in the Study Eye at Month 48

5. Study Description

Brief Summary

This study is a Phase III, double-masked, multicenter, randomized, sham injection-controlled study of the efficacy and safety of ranibizumab injection in patients with clinically significant macular edema with center involvement (CSME-CI) secondary to diabetes mellitus (Type 1 or 2). This study is identical in design to study NCT00473330 (Protocol ID FVF4170g). The open-label extension phase of the study was stopped after receiving FDA approval of the study drug (ranibizumab) for diabetic macular edema.

Detailed Description

This study is composed of 3 phases: (1) A 24-month controlled treatment period (monthly treatment with ranibizumab 0.3 mg, ranibizumab 0.5 mg, or sham injection) followed by (2) a 12-month treatment period in which patients randomized to the sham group who had not discontinued from treatment (still masked) could choose to receive monthly ranibizumab 0.5 mg while the 2 ranibizumab treatment groups continued on the same treatment they received in the first 2 years. Patients who had not discontinued treatment by Month 36 were eligible to continue treatment with ranibizumab 0.5 mg as needed (pro re nata, PRN) in (3) an extension phase of the study for up to 2 more years, resulting in up to 5 years possible total treatment time for some patients. As per the protocol, Genentech terminated the study approximately 30 days after approval of ranibizumab for diabetic macular edema in the United States.
