A 12 Month Core Study to Assess the Efficacy and Safety of Ranibizumab (Intravitreal Injections) in Patients With Visual Impairment Due to Diabetic Macular Edema and a 24 Month Open-label Extension Study (RESTORE)
A Randomized, Double-masked, Multicenter, Laser-controlled Phase III Study Assessing the Efficacy and Safety of Ranibizumab (Intravitreal Injections) as Adjunctive and Mono-therapy in Patients With Visual Impairment Due to Diabetic Macular Edema
CRFB002D2301: The core study was designed to confirm the efficacy and safety of ranibizumab (0.5 mg) as adjunctive therapy when added to laser photocoagulation and/or mono-therapy in patients with visual impairment due to diabetic macular edema.
CRFB002D2301E1: A 24 month open-label extension study for participants who completed the 12 month core study evaluated the long-term safety and efficacy of ranibizumab (0.5 mg) as symptomatic treatment for visual impairment due to diabetic macular edema.

Experimentell: Ranibizumab 0.5 mg
Ranibizumab 0.5 mg was administered monthly by intravitreal injection in the study eye for 3 months. After the third injection, treatment was suspended if either one of the following criteria was met: Improvement in best corrected visual acuity (BCVA) could not be attributed to treatment at the last 2 visits, in the opinion of the investigator, or BCVA > 84 letters (approximate Snellen equivalent of 20/20) was observed at the last 2 last visits. Patients also received sham laser treatment on Day 1 and subsequently at intervals of at least 3 months, if deemed necessary by the evaluating physician. Active/sham laser treatment was always administered before (sham) intravitreal injections. The minimum interval between the 2 treatments was 30 minutes. In the extension study at the investigator's discretion, patients received open-label ranibizumab 0.5 mg intravitreal injections once a month until stable vision was reached (a maximum of 24 injections) and could receive laser therapy. |

Experimentell: Ranibizumab 0.5 mg + laser
Ranibizumab 0.5 mg was administered monthly by intravitreal injection in the study eye for 3 months. After the third injection, treatment was suspended if either one of the following criteria was met: Improvement in best corrected visual acuity (BCVA) could not be attributed to treatment at the last 2 visits, in the opinion of the investigator, or BCVA > 84 letters (approximate Snellen equivalent of 20/20) was observed at the last 2 last visits. Patients also received active laser treatment on Day 1 and subsequently at intervals of at least 3 months, if deemed necessary by the evaluating physician. Active/sham laser treatment was always administered before (sham) intravitreal injections. The minimum interval between the 2 treatments was 30 minutes. In the extension study at the investigator's discretion, patients received open-label ranibizumab 0.5 mg intravitreal injections once a month until stable vision was reached (a maximum of 24 injections) and could receive laser therapy. |

Core Study: Difference Between the Baseline Level of Visual Acuity (Letters) of the Study Eye and the Mean Visual Acuity Averaged Over All Monthly Post-baseline Assessments From Month 1 to Month 12
Tidsram: Baseline through the end of study (Month 12)
|
Visual acuity (VA) was assessed on both eyes during every study visit using best correction determined from protocol refraction.
VA measurements (number of letters correctly identified) were performed with the patient in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts at a testing distance of 4 meters.

Extension Study: Percentage of Participants With Ocular Adverse Events (AEs) in the Study Eye in the 24 Month Extension Study
Tidsram: Extension baseline (Month 12 -end of core study) to Month 36 (end of extension study) [24 Months]
|
Participants with ocular (occurring in the eye) serious adverse events (SAEs) and non-serious AEs in the study eye. The study eye is the eye that received the treatment. AEs are the appearance or worsening of any undesirable sign, symptom, or medical condition occurring after starting the study drug even if the event is not considered to be related to study drug. A serious adverse event is defined as an event that is fatal or life-threatening, results in persistent or significant disability/incapacity, constitutes a congenital anomaly/birth defect, requires inpatient hospitalization or prolongation of existing hospitalization or is medically significant. Additional information about adverse events can be found in the Adverse Event section. |

Core Study: Mean Change From Baseline in Patient-reported Visual Functioning
Tidsram: Baseline to Month 12
|
The National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) was used to measure a patient's subjective assessment of vision-related quality of life.
The 12 subscales in the VFQ-25 are general health, general vision, ocular pain, near activities, distance activities, social function, mental health, role difficulties, dependency, driving, color vision, and peripheral vision.
The scores on the subscales were added together for a total score, which ranged from 0 to 100.
A higher score indicated improvement in quality of life due to vision function.
