Efficacy and Safety of Conbercept for Diabetic Macular Edema Combined With Severe Non-proliferative Diabetic Retinopathy

The Efficacy and Safety of Conbercept for Diabetic Macular Edema Combined With Severe Non-proliferative Diabetic Retinopathy: 12-month Results From a Prospective Multicenter Open Label Study

Source: ClinicalTrials.gov · Last updated 30 May 2025

Brief summary (registry, in English)

The goal of this prospective multicenter open label study is to evaluate the efficacy and safety of intravitreal injection Conbercept (IVC) for the treatment of diabetic macular edema (DME) combined with severe nonproliferative diabetes retinopathy (sNPDR). The main questions it aims to answer are: * mean changes in best corrected visual acuity (BCVA) and central macular thickness (CMT) in comparison with baseline at 12 months after initial treatment * proportion of eyes with visual gain ≥15 letters in Early Treatment Diabetic Retinopathy Study (ETDRS) chart and ≥2-step improvement in Diabetic Retinopathy Severity Scale (DRSS) score after 12 months of the treatment * proportion of eyes actually underwent PRP treatment after 3 and 12 months of the treatment * mean changes in BCVA and CMT from baseline to monthly follow-up time point * complications and adverse effects

Built from the registry fields of ClinicalTrials.gov. It describes the study, not your situation.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • concomitant or previous macular diseases that may hinder visual improvement other than diabetic retinopathy (e.g., retinal vein occlusion, age-associated macular degeneration, uveitis, vitreomacular traction or epiretinal membrane)
  • previous vitreoretinal surgery or pan-retinal photocoagulation
  • intravitreal injection anti-VEGF drugs within 6 months or intravitreal injection glucocorticoid within 3 months

Other illness

  • history of glaucoma or optic neuropathy of any kind

Other

  • macular focal/grid laser photocoagulation within 3 months

Who the study is looking for

  • symptomatic patients aged 18 years or above with center involved diabetic macular edema in the involved eye and without clinically significant diabetic macular edema in the fellow eye defined on the basis of spectral-domain optical coherence tomography (OCT)
  • central macular thickness (CMT) ≥300 μm measured by OCT
  • the involved eyes diagnosed as severe non-proliferative diabetic retinopathy (sNPDR) confirmed by two independent experienced ophthalmologists based on the ETDRS standard seven field color fundus photographs

Age in the registry: 18 years to - · Sex: All · Does not accept healthy volunteers
