Co-Founders
Ranjit Bindra, MD, PhD
Professor, Yale Medical School
Dr. Ranjit Bindra is a physician-scientist at the Yale School of Medicine and Co-Director of the Yale Brain Tumor Center. His group recently reported the stunning discovery that 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, Nature Genetics, and Nature, and it has received international attention with major clinical implications. Dr. Bindra is now translating this work directly into patients, in four phase I/II clinical trials. In addition, he is co-PI of a 35-site, NCI-sponsored Phase II trial testing the PARP inhibitor, olaparib, in adult IDH1/2-mutant solid tumors (NCT03212274).
As a biotech entrepreneur he co-founded Cybrexa Therapeutics, a clinical stage company developing a new class of tumor-targeted DNA damaging agents.
Dr. Bindra received his undergraduate degree in Molecular Biophysics and Biochemistry from Yale University in 1998, and both his MD and PhD from the Yale School of Medicine in 2007. He completed his medical internship, radiation oncology residency, and post-doctoral research studies at the Memorial Sloan-Kettering Cancer Center (MSKCC) in 2012.
Charles Brenner, PhD
Professor and Chair, City of Hope
Charles Brenner is one of the world’s leading experts on nicotinamide adenine dinucleotide (NAD), the central catalyst of metabolism. He discovered the vitamin activity of nicotinamide riboside (NR) and the eukaryotic NR kinase pathway and developed targeted quantitative NAD metabolomic technologies that uncovered the phenomenon that the NAD metabolome is frequently disturbed in conditions of metabolic stress. He runs an active research program on mechanistic dissection and translation of NAD dysregulation as the Alfred E. Mann Chair of the new Department of Diabetes and Cancer Metabolism at City of Hope National Medical Center in Duarte, California. Prior to his faculty position at City of Hope, Charles held faculty positions at Thomas Jefferson University, Dartmouth College and most recently, the University of Iowa.
Charles is an experienced advisor for biotechnology companies including roles on the scientific advisory board of Cytokinetics and Ridgeline. He also currently serves as the Chief Scientific Advisor for ChromaDex.
