Efficacy and Safety of Conbercept for Diabetic Macular Edema Combined With Severe Non-proliferative Diabetic Retinopathy
China58 participantsStarted 2024-04-01
Plain-language summary
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

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 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
Exclusion Criteria:
* 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)
* history of glaucoma or optic neuropathy of any kind
* previous vitreoretinal surgery or pan-retinal photocoagulation
* intravitreal injection anti-VEGF drugs within 6 months or intravitreal injection glucocorticoid within 3 months
* macular focal/grid laser photocoagulation within 3 months
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
