Must have
Male or female patients ≥50 years of age
Active CNV membranes with subfoveal leakage or juxtafoveal leakage too close for laser photocoagulation
Must not have
Patients having additional eye disease in the posterior segment of study eye other than wAMD
Any other pathology involving the CNV lesion like retro foveolar atrophy or permanent structural damage to fovea or fibrosis/ hemorrhage involving fovea > 50 % of lesion area of study eye that can affect the efficacy of drug
Timeline

Summary

This trial will compare a new eye drop for age-related macular degeneration to a placebo to assess safety and effectiveness.

Who is the study for?
This trial is for men and women over 50 with wet age-related macular degeneration (wAMD) in one eye. They must have certain levels of vision clarity, a specific thickness in the retina, and active blood vessel growth under the fovea. Women must be non-childbearing or using birth control. Excluded are those with other major eye diseases, recent surgeries, uncontrolled health conditions like diabetes or hypertension, or who've had certain wAMD treatments recently.
What is being tested?
The study tests CG-P5 peptide eye drops against a placebo to see if they're safe for people with wAMD. It's randomized: participants don't choose their treatment group. Some will get the real drug; others won't (placebo). A known treatment called Aflibercept [Eylea] is also part of the study for comparison purposes.
What are the potential side effects?
While side effects aren't detailed here, typical ones from eye drops may include irritation at the application site, redness, discomfort or itching in the eyes. Since this trial includes an injection (Aflibercept), there could also be risks associated with injections such as infection or inflammation.
