Description

Summary

The study's main purpose is to asses the safety, tolerability, and effect of oral administration of RG7774 on the severity of diabetic retinopathy (DR) in participants with moderately severe to severe non-proliferative diabetic retinopathy (NPDR) and good vision.

Official Title

A Randomized, Double-Masked, 48-Week, Parallel-Group, Placebo-Controlled, Proof-of-Concept Study to Investigate the Efficacy and Safety of RG7774 in Patients With Diabetes Mellitus Type 1 or Type 2 With Treatment-Naive Diabetic Retinopathy

Keywords

Diabetic Retinopathy Retinal Diseases Diabetes Mellitus Diabetes Mellitus, Type 1

Ocular criteria for study eye:

  • Prior treatment for DR or other retinal diseases with any approved or investigational therapy, including but not limited to intravitreal steroids, intravitreal anti-VEGF, light therapy, periocular pharmacological intervention, and laser (e.g. focal, grid, micropulse, or pan-retinal)
  • Uncontrolled glaucoma
  • Any concurrent intraocular condition (e.g. retinal detachment, dense cataract, epiretinal membrane with traction, or vitreomacular traction, etc.) that in the opinion of the Investigator could reduce the potential for improvement, require medical surgical intervention or may confound the visual and functional assessment and interpretation of study results

Concurrent ocular conditions in either eye:

  • Any active ocular infection
  • Any active intraocular inflammation

General Criteria:

  • Previous systemic use of anti-VEGF drugs within 6 months prior to screening
  • Complications of diabetes such as end-stage renal disease or liver disease
  • Currently untreated diabetes mellitus or previously untreated patients who initiated oral or injectable anti-diabetic medication within 3 months prior to screening
  • Uncontrolled blood pressure ([BP] defined as systolic > 180mmHg and/or diastolic >100 mmHg while patient at rest)
  • History of concurrent cardio-vascular disease not considered well controlled by the Investigator
  • Any major illness or major surgical procedure within one month before screening
  • History of or currently active other diseases, metabolic dysfunction, physical examination finding, malignancies not considered cured, or clinical laboratory findings giving reasonable suspicion of a condition that contraindicated the use of the investigational medicinal drug or that might affect interpretation of the results of the study or renders the patient at high risk for treatment complications in the opinion of the investigator
  • Known hypersensitivity to any of the excipients of the drug used, fluorescein dye or dilating eye drops
  • Use of systemic medications known to be toxic to the lens, retina or optic nerve (e.g., deferoxamine, chloroquine/hydroxychloroquine, tamoxifen, phenothiazines and ethambutol) used during the 6-month period prior to screening or likely need to be used
