Under his leadership, the MedStar-Georgetown Radiation Oncology Program was one of the first to establish a CyberKnife radiation therapy program and a Mevion proton therapy site. Dr. Dritschilo has served as an advisor to the NIH and the American Cancer Society on research funding and also has served on the Board of Directors of the National Coalition for Cancer Research, on the Roster of Distinguished Scientific Advisors to the Radiological Society of North America. He is a member of the American Association of Cancer Research, American Society for Clinical Oncologists, American Society of Therapeutic Radiation Oncologists and the Radiation Research Society.  Dr. Dritschilo is also a co-inventor of patents in radiosurgery and stereotactic radiation therapy methods, radiation sensitizing drugs and personalized methods of treatment of cancer patients.  Dr. Dritschilo co-founded Shuttle Pharmaceuticals, LLC in December 2012 and has served as its Chairman of the Board and Chief Executive Officer since then.

About Dr. David A. Horwitz:
Dr. David Horwitz, MD is a physician-scientist and immunologist who is internationally recognized for his work in T-cell biology, especially related to immune regulation. He has served as Professor of Medicine and Molecular Immunology and Chief of Division of Rheumatology and Immunology at the University of Southern California (USC) Keck School of Medicine for 27 years.  He served as a Professor of Medicine at the University of Virginia, Charlottesville, VA before joining USC.  Dr. Horwitz is a Member of the American Society for Clinical Investigation (ASCI), an honor society for physician-scientists, and an active member of several professional organizations.  He is a Master of the American College of Rheumatology.

As a pioneering researcher and physician-scientist, Dr. Horwitz has characterized many abnormalities of the immune system in patients with systemic lupus erythematosus. He was the first to recognize the role of IL-2 and TGF-β in the development of regulatory/suppressor T-cells, an observation that is now immunological dogma. The primary objective of his internationally recognized academic career has been to utilize our increasing knowledge of the immune system to develop a therapy that is more effective, yet safer than the agents now used to treat systemic lupus erythematosus, other autoimmune diseases, graft versus host disease, and allograft rejection. Dr. Horwitz holds several patents on methods for treating immunologic diseases.  He published more than 100 research articles in high impact medical-scientific journals.  He is Co-Founder of Toralgen, Inc. and Chief Executive Officer of General Nanotherapeutics, LLC.  Dr. Horwitz has been developing orally delivered bile acid nanoformulations of small molecules and biologics for treatment of autoimmune diseases.  He will provide expert guidance regarding the potential application of the oral nanoformulation platform for the delivery of the Oncotelic RNA therapeutic as a “nano pill” in pancreas cancer patients.  

About Dr. Reinhard von Roemeling:

Dr. Reinhard von Roemeling, MD is an internationally recognized medical oncologist and clinical scholar with deep knowledge and experience in oncology drug development.  During his academic career, Dr. von Roemeling served as a faculty member and attending medical oncologist at the University of Minnesota, Texas University Health Sciences Center, Albany Medical College and VA Medical Center, and Fox Chase Comprehensive Cancer Center.  He has extensive global experience successfully designing robust protocols and advancing clinical trials encompassing both strong clinical and research components within large portfolios. Dr. von Roemeling directed/co-directed/supported 25+ small molecules and biologics development programs, including 10 as immunotherapy/immune-modulators in combination with other drugs (PD-(L)1 checkpoint inhibitors.
