Details and patient eligibility

About

The study was designed to assess the efficacy and safety of Lucentis® (ranibizumab 0.5 mg) in diabetic patients presenting with reduced visual acuity due to diabetic macular edema and evaluating spacing out of follow-up after initial intensive treatment phase.

Full description

This was a multicenteric, open-label, phase IIIb study, which comprised of 2 groups: the Main Group and the Rescue Group.

Patient's eligibility was assessed during a screening visit (Visit 1) which took place 14 days maximum before treatment initiation (Visit 2 [Day 0]). All patients were initially included in the Main Group and were to receive an initial loading treatment (6 injections during the intensive treatment phase i.e. every month from Day 0 to Month 5, followed by 2 additional injections at Months 8 and 11). Patients were to be followed-up every 3 months for 18 months (spaced-out follow-up period). Their visual acuity was to be checked at each study visit (Months 3, 6, 8, 11, 14, 17, 20, and 23) to assess their response to treatment. Patients who responded to treatment were maintained in the Main Group. Patients who did not meet pre defined criteria were moved to the Rescue Group and treated at the investigator's discretion.

The trial was terminated before any patient reached month 12.
