The goal of this clinical trial is to assess the efficacy and safety of multiple doses of foselutoclax (UBX1325) in patients with Diabetic Macular Edema. The main questions the study aims to answer are: * Assess the efficacy of foselutoclax compared to aflibercept * Assess the safety and tolerability of foselutoclax
This study is intended to assess the efficacy and safety of foselutoclax, a phosphate pro-drug, and its active parent molecule (UBX0601, a BCL-xL inhibitor) following repeat intravitreal (IVT) injections of foselutoclax in patients with Diabetic Macular Edema (DME). Approximately 50 patients will be enrolled and randomized 1:1 into either the foselutoclax arm,10 μg given 8 weeks apart, or the control arm of aflibercept, 2 mg every 8 weeks in order to assess the primary objective. All patients will be followed for approximately 36 weeks. The injector will be unmasked but the evaluator will remain masked throughout the study. This study will enroll participants ≥18 years of age with active DME disease despite treatment, with best corrected visual acuity (BCVA) between 70 to 30 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (equivalent to 20/40 to 20/250 on the Snellen chart). Once patients meet inclusion/exclusion criteria, patients will receive 3 run-in injections of aflibercept approximately 4 weeks apart, with the last aflibercept injection 4-6 weeks prior to Day 1.

Assess Other Efficacy Outcome - Rescue Metrics
At any visit, including Unscheduled visits, patients who exhibited increase in disease activity, were allowed to be rescued with aflibercept. Increase in disease activity was defined as ANY of the following: * Worsening CST by ≥75 µm from baseline per SD-OCT * A ≥10 letter decrease in BCVA compared to baseline * New clinically significant blood or heme present compared to previous visit * PI discretion (rationale to be documented in the EDC)
Time frame: 36 weeks
Assess Safety Outcome - Safety and Tolerability

Time frame: 36 weeks
Ocular Safety and Tolerability
Ocular Safety is evaluated by incidence of ocular Treatment Emergent Adverse Events (TEAEs).
Time frame: 36 weeks
