Can your genes predict which eye drug works best?
NCT ID NCT06952452
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial is testing whether a person's genetic makeup influences how well they respond to two standard drugs for wet age-related macular degeneration: ranibizumab and bevacizumab. About 630 patients will receive one of the two drugs and be followed for three years. The goal is to see if certain gene variants are linked to better or worse vision outcomes, which could help personalize treatment in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ranibizumab and bevacizumab (anti-VEGF drugs injected into the eye)
- What this could lead to
- If successful, this could help doctors choose the most effective anti-VEGF drug for each patient based on their genetics, potentially improving vision outcomes and reducing costs.
- What could go wrong
- This is a large phase 3 trial, but it focuses on genetic markers that may not strongly predict treatment response. The results may not change clinical practice if the genetic links are weak.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients diagnosed with neovascular Age-related Macular Degeneration * Age of 50 years or older. * That at the discretion of the ophthalmologist has an indication of receiving treatment with an anti-VEGF agent as usual in clinical practice. * Without previous treatment in the eye under study (no previous treatment for AMD). Exclusion Criteria: * Participate or have participated in another clinical trial with an experimental drug in the last 6 months. * Patients with other eye diseases, p. eg, advanced glaucoma or visually significant cataracts, which are likely to require surgery during the follow-up period in the eye under study. * Concomitant, ocular or systemic, administration of drugs up to 3 months before the treatment with another anti-VEGF in the contralateral eye. * High cardiovascular risk: poorly controlled arterial hypertension, history or risk of arterial thromboembolic events, history of stroke or acute myocardial infarction, anticoagulant treatment, proteinuria or major elective surgery within 3 months. * Ophthalmological risk with the intraocular injection (all intravitreal treatments): active or suspected ocular or periocular infection, severe blepharitis, history of endophthalmitis, history of retinal detachment, myopathy, glaucoma. * Hypersensitivity to the active substance or to the excipients. * Diabetic retinopathy documented. * Pregnant or nursing (lactating) women. Patients who meet elegibility criteria and decline participation due to treatment randomization, will participate in an observational follow-up, collecting saliva for the analysis of genetic polymorphisms and clinical data related to antiVEGF received out of the clinical trial and AV, OCT results and adverse events registered in medical records at 6m, 12m, 24m, 36m.
