Dr. Kovach trained in Internal Medicine and Hematology at Presbyterian Hospital, Columbia University and spent six years in the laboratory of Chemical Biology at the National Institute of Arthritis and Metabolic diseases studying control of gene expression in bacterial systems.

Dr. Kovach was recruited to the State University of New York at Stony Brook (“SUNY – Stony Brook”) in Stony Brook, New York in 2000 to found the Long Island Cancer Center (now named the Stony Brook University Cancer Center). From 1994 to 2000, Dr. Kovach was Executive Vice President for Medical and Scientific Affairs at the City of Hope National Medical Center in Los Angeles, California. His responsibilities included oversight of all basic and clinical research initiatives at the City of Hope. During that time, Dr. Kovach was also Director of the Beckman Research Center at City of Hope and a member of the Arnold and Mabel Beckman Scientific Advisory Board in Newport Beach, California.

From 1976 to 1994, Dr. Kovach was a consultant in oncology and director of the Cancer Pharmacology Division at the Mayo Clinic in Rochester, Minnesota. During this time, he directed the early clinical trials program for evaluation of new anti-cancer drugs as principal investigator of contracts from the National Cancer Institute. From 1986 to 1994, he was also Chair of the Department of Oncology and Director of the NCI-designated Mayo Comprehensive Cancer Center. During that time, Dr. Kovach, working with a molecular geneticist, Steve Sommer, M.D., Ph.D., published extensively on patterns of acquired mutations in human cancer cells as markers of environmental mutagens and as potential indicators of breast cancer patient prognosis. Dr. Kovach has published over 100 articles on the pharmacology, toxicity and effectiveness of anti-cancer treatments and on the molecular epidemiology of breast cancer.

Effective February 23, 2017, Dr. Kovach retired from his part-time (50%) academic position at SUNY – Stony Brook, as a result of which he has been devoting 100% of his time to our business activities since that date.

Dr. Palmedo designed and was the first President of the Long Island Research Institute formed by Brookhaven National Laboratory, Cold Spring Harbor Laboratory, and SUNY – Stony Brook to facilitate the commercialization of technologies. In 1988, Dr. Palmedo joined in the formation of Kepler Financial Management, Ltd., a quantitative financial research and trading company. He was President and Managing Director until 1991, when Renaissance Technologies Corporation acquired the company.

Dr. Palmedo served on the boards of Asset Management Advisors, the Teton Trust Company, EHR Investments and C-Quest Capital, and is currently a member of the Board of Directors of Gyrodyne LLC.

Dr. Stephen J. Forman


Stephen J. Forman, M.D., is an internationally recognized expert in hematologic malignancies and bone marrow transplantation and is a leader in preclinical and clinical cancer research. He is co-editor of Thomas’ Hematopoietic Cell Transplantation, a definitive textbook for clinicians, scientists and health care professionals. Dr. Forman is the Francis and Kathleen McNamara Distinguished Chair in Hematology and Hematopoietic Cell Transplantation at the City of Hope Comprehensive Cancer Center, a position he has held since 1987.

In nearly 40 years at City of Hope, Dr. Forman has been instrumental in advancing the survival rates for patients suffering from cancers of the blood and immune system such as leukemia, lymphoma and myeloma.

As Director of the T Cell Immunotherapy Research Laboratory, his current research is focused on cancer immunotherapy, using the body’s own immune system to attack cancer. Pharmacological enhancement of patients’ immune responses to their cancers is of special interest to us as the enzyme target of its lead clinical compound, LB-100, has been reported recently to be critical to immune function. Much of Dr. Forman’s current work centers on T cells and their cancer-fighting potential.

Dr. Winson Sze Chun Ho


Winson Sze Chun Ho, M.D., is presently a pediatric neurosurgery fellow at the University of Utah School of Medicine. After receiving his M.D. from Yale University School of Medicine in 2011, Dr. Ho had four years of training in Neurosurgery at the University of Virginia, Charlottesville, Virginia. Prior to his final year as chief resident at the University of Virginia, Dr. Ho spent three years doing molecular pharmacologic research on methods to enhance the efficacy of cancer therapy as a Clinical and Research Fellow in the Surgical Neurology Branch, National Institute of Neurological Disorders and Stroke, National Institutes of Health. His research included several studies of our lead clinical compound, the protein phosphatase 2A inhibitor LB-100, including the demonstration that LB-100 potentiates the effectiveness of the immune checkpoint blocker PD-1 in several preclinical models. These results were recently published in the scientific journal Nature Communications.
