A Phase 3 interventional study of Bevacizumab and Lucentis® in Diabetic Macular Edema, sponsored by Laboratorios Sophia S.A de C.V.. Completed at 1 site in Mexico. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-22.
Sponsored by Laboratorios Sophia S.A de C.V. · Phase 3, Interventional, and Treatment
Phase III clinical study to evaluate the efficacy, expressed as improvement in visual acuity in patients suffering diabetic macular edema after one year of treatment with PRO-169, compared to treatment with Lucentis® (ranibizumab).
A total of 442 patients with diabetic macular edema will be randomized 1:1 to be treated with either PRO-169 (bevacizumab) or Lucentis® (ranibizumab). There will be a total of 14 visits, including selection and final visits. Monthly evaluations will include ophthalmologic evaluations of anterior and posterior segments, as well as OCT (optic coherence tomography) to obtain central macular width and retinal volume. Fluorescein angiography will be performed on selection visit as well as 6 and 12 months into the study (visits 7 and 13). All patients will be exposed to intravitreal injection of either of the studied drugs monthly for the first 4 months. Starting on visit 5 patients will be injected depending on their response to treatment, calculated according predetermined algorithms including clinical and image variables. Starting on month 6, patients may be subjected to rescue therapy with photocoagulation if they comply with predetermined criteria for such measure.
Exclusion Criteria:
Bevacizumab 1.25 mg / 0.05mL for intravitreal injection. All patients in this arm will be exposed to one monthly injection for the first four months. During the rest of the study, during the monthly visits, it will be decided if injections are to be continued or postponed. The maximum amount of intravitreal injections to be administered are 12.
Biological: Bevacizumab
Ranibizumab 0.5 mg / 0.05mL for intravitreal injection. All patients in this arm will be exposed to one monthly injection for the first four months. During the rest of the study, during the monthly visits, it will be decided if injections are to be continued or postponed. The maximum amount of intravitreal injections to be administered are 12.
Biological: Lucentis®
Administration of monthly intravitreal bevacizumab (4-12 injections)
Administration of monthly intravitreal ranibizumab (4-12 injections)
