Bio: David R.P. Almeida, MD, MBA, PhD, is an investigator with Erie Retina Research and the Centers for Advanced Surgical Exploration (caseX). His work includes clinical research in retina, including diabetic macular edema and investigational intravitreal gene therapy. At the 2025 American Society of Retina Specialists annual meeting, Dr. Almeida presented interim results from SPECTRA, a phase 2a multicenter trial evaluating 4D-150 for adults with diabetic macular edema. The study assessed safety and clinical activity after aflibercept loading injections followed by a single 4D-150 injection.
