Is this trial a fit for you?
✓Likely a good fit
Adults with Type 1 or Type 2 diabetes and Diabetic Macular Edema, treatment-naïve or previously treated, able to consent.
✕Probably not a fit
Patients with active iris or angle neovascularization, neovascular glaucoma, or a history of retinal detachment in the study eye may not benefit from this trial.

What this trial studies
This Phase 3 trial compares Tabirafusp Tedromer to Aflibercept 2.0 mg in adults with DME. Participants are randomized to receive either the experimental antibody biopolymer conjugate or the standard anti-VEGF therapy, with safety and efficacy monitored over time. Eligible participants include adults with diabetes and DME, regardless of prior treatment status, who meet specific health criteria. Primary outcomes typically include changes in vision and retinal thickness, along with safety assessments. The study is conducted at Kodiak Research Centers in Scottsdale, Bakersfield, and Glendale, California.
Why it matters
Potential benefit: If successful, participants may experience improved vision and retinal health, and this approach could offer an alternative treatment option for DME.
How similar studies have gone: Other anti-VEGF or antibody-based therapies have shown benefit in DME; this study tests a novel Tabirafusp Tedromer approach.
