1 A fresh approach to Immuno-oncology: Ex vivo analysis of drug efficacy in fresh patient tumortissue Soner Altiok, MD, PhD Chief Scientific Officer Nilogen Oncosystems Tampa, Florida

2 - Nilogen Oncosystems, a CLIA-certified laboratory, is dedicated to the improvement of cancer drug development for pharmaceutical and biotechnology companies. - Nilogen s proprietary drug testing platforms utilize fresh patient tumor tissue with intact tumor immune microenvironment to accurately assess the efficacy of immunotherapeutics.

3 Cancer immunotherapy delivers treatment of high specificity, low toxicity and prolonged activity in subsets of patients. Courtesy of Scott Antonia, MD, PhD, Chief Medical Officer
