A Study Assessing the Safety, Tolerability, and Efficacy of RG6147 in Participants With Geographic Atrophy Secondary to Age-Related Macular Degeneration (AMD) (GALLEGO)

This study will evaluate the safety, tolerability, and efficacy of intravitreal injections of RG6147 administered every 4 weeks (Q4W) or every 8 weeks (Q8W) for approximately 76 weeks in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) compared with sham control. After completing the study's last visit (Week 76), eligible participants will have the option to enroll in open-label extension study NCT03972709 (GR42558) and receive open-label RG6147 injections.

• Well-demarcated area of GA secondary to AMD with no evidence of prior or active choroidal neovascularization (CNV) in either eye.
Exclusion Criteria:
Ocular Exclusion Criteria, Study Eye:
• History of vitrectomy surgery, submacular surgery, or any surgical intervention for AMD;
• Previous laser photocoagulation or ITV anti-vascular endothelial growth factor (anti-VEGF) for CNV, diabetic macular edema, retinal vein occlusion, or proliferative diabetic retinopathy. Ocular Exclusion Criteria, Both Eyes:

• Active uveitis and/or vitritis (grade trace or above) in either eye;
• Active, infectious conjunctivitis, keratitis, scleritis, or endophthalmitis in either eye;
• Retinal pigment epithelium (RPE) tear that involves the macula in either eye;
• Previous participation in interventional clinical trials for GA or dry AMD, except for vitamins and minerals, regardless of the route of administration (i.e., ocular or systemic) within the last 6 months.

Does Insulin Sensitivity Impact the Potential of Metformin to Slow Aging

Aging is the number one risk factor for the majority of chronic diseases. There are no pharmaceutical treatments to slow aging and prolong healthspan. The anti-diabetic drug metformin is considered a likely pharmaceutical candidate to slow aging. In this study, the investigators hypothesize that metformin treatment in subjects free of type 2 diabetes will improve insulin sensitivity and glucoregulation in insulin resistant individuals, but will decrease insulin sensitivity and glucoregulation in insulin sensitive subjects. Further, the investigators hypothesize that long-term metformin treatment will remodel mitochondria in a way that decreases mitochondrial function in subjects that are insulin sensitive, but improves mitochondrial function in subjects that are insulin resistant. The investigators will use a dual-site, 12- week drug intervention trial performed in a double-blind, placebo-controlled manner on 148 subjects recruited from two separate sites (Oklahoma Medical Research Foundation (OMRF) and University of Wisconsin-Madison (UWM)). After consent and initial subject screening for chronic disease, subjects will be stratified to insulin sensitive (IS) or insulin resistant (IR) groups. Over a 12- week intervention, half of each group will take metformin and half will take a placebo. Pre- and post--intervention, subjects will complete a series of procedures to assess insulin sensitivity, glucose regulation, and biomarkers of aging. The same subjects will provide a skeletal muscle biopsy pre-- and post-intervention to assess the change in mitochondrial function and mitochondrial remodeling with and without metformin treatment. By completion of this project, the investigators expect to provide evidence that helps further delineate who may benefit from metformin treatment to slow aging.
