Previously appointed members of Cybrexa’s SAB include:

Dr. Ranjit Bindra is a physician-scientist and biotech entrepreneur at the Yale School of Medicine and a co-founder of Cybrexa. Clinically, Dr. Bindra treats adult and pediatric primary CNS tumors, and he is a member of the Yale radiosurgery team, with expertise in treating brain metastases and benign tumors such as arteriovenous malformations. Dr. Bindra also runs Phase I and II clinical trials at Yale, which are largely based on discoveries from his own laboratory. Dr. Bindra’s group led four major laboratories at Yale discovering IDH1/2-mutant tumors harbor a profound DNA repair defect that renders them exquisitely sensitive to PARP inhibitors. This work was published in Science Translational Medicine and has received international attention with major clinical implications. As a biotech entrepreneur, Dr. Bindra has started two life sciences ventures over the last decade and is incubating a third company via a Program in Innovative Therapeutics for Connecticut’s Health (PITCH) award at Yale. Dr. Bindra received his undergraduate degree in Molecular Biophysics and Biochemistry from Yale University, and both his M.D. and Ph.D. from the Yale School of Medicine. He completed his medical internship, radiation oncology residency, and post-doctoral research studies at the Memorial Sloan-Kettering Cancer Center.

Dr. Peter Glazer is currently the Hunter Professor and Chairman of the Department of Therapeutic Radiology and Professor of Genetics at Yale. Dr. Glazer lab’s main focus has been on elucidating the regulation of DNA repair in cancer and developing novel agents to exploit DNA repair for cancer therapy. He is credited with making the seminal observation that tumor hypoxia promotes genetic instability, and he has systematically dissected the mechanism for this effect, revealing that DNA repair is dysregulated in hypoxic cancer cells. Dr. Glazer has also pioneered the use of triplex-forming oligonucleotides for targeted gene editing, with recent work demonstrating successful gene editing in a living animal by simple intravenous administration of oligonucleotide-containing nanoparticles, providing a potentially safer and simpler alternative to CRISPR. Dr. Glaser Glazer served as Chairperson of the Radiation Therapeutics and Biology Study Section for NIH, as well as on councils and program committees for several national societies. He has also led the Yale Cancer Center’s Radiobiology & Radiotherapy research program for more than 20 years.
