SGLT2 Inhibitors in Geographic Atrophy

Q: Who can participate in NCT07174687?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT07174687?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

Efficacy of Dapagliflozin in the Progression of Geographic Atrophy Secondary to Age-Related Macular Degeneration

SGLT2 Inhibitors in Geographic Atrophy (NCT07174687) is a Phase 2 interventional studying Retinal Degeneration and Retinal Diseases, sponsored by Washington University School of Medicine. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

AMD is a leading cause of blindness in individuals over 50 years old, with dry AMD being the most common form. Geographic atrophy (GA) is an advanced stage of dry AMD characterized by progressive retinal cell degeneration. The primary objectives of the study are to assess the safety, tolerability, and evidence of activity of SGLT2 inhibitors in subjects with Geographic Atrophy associated with AMD.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Retinal Degeneration and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 70 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Retinal Degeneration subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Capable of giving signed willing to sign a consent form, which includes compliance with the requirements and restrictions listed in the ICF and in this protocol 2. Are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedures 3. Participant is male or, if female, participant is surgically sterilized or amenorrheic for at least one year 4. ≥50 years old 5. Evidence of dry advanced AMD with the presence of non-foveal Geographic Atrophy (GA) 1. The geographic atrophy must not involve the center point of the fovea. 2. Total area of geographic atrophy must be between 2.5 mm2 and 17.5 mm2 (1 - 4 disc areas, respectively). 3. If the geographic atrophy consists of multiple lesions, at least one lesion must have an area of ≥1.25 mm² (equivalent to 0.5 disc areas). 6. BCVA between 20/25 and 20/320 7.
