He stayed in his hometown near Frankfurt/Main until completion of high school when he decided to join a Catholic church group for a mandatory civilian service. Henning has been dedicated to patient care since he started working with patients and elderly with special needs during this period of civilian service. This inspired him to join nursing school for a 3-year training to become licensed nurse.

Dr. Schade has published several scientific articles, abstracts and posters at ASCO, ASH and EBMT, including his doctoral thesis about second allogeneic stem cell transplantation in patients with relapsed hematologic malignancy. During his time as an internal medicine resident at MUSC he worked in Dr. Yubin Kang’s lab on Multiple Myeloma cell lines and became interested in translational research. During his fellowship in Hematology/Oncology at the University of Colorado he worked in Brent Palmer’s lab and studied PD-1 expression on CD4+ T cells and CMV+ T cells after allogenic stem cell transplantation. The results were published in BBMT in 08/2016. These findings were the fundamental basis for his upcoming research projects.

Dr. Schade’s research interest is primarily in the treatment of plasma cell and lymphoid diseases. He is the primary investigator for several clinical studies that investigate novel treatment options for patients with Multiple Myeloma and Hodgkin lymphoma. He also has a strong research interest in immune reconstitution after autologous and allogenic stem cell transplantation and has published his research in journals such as BBMT. At The Colorado Blood Cancer Institute he developed an investigator initiated a phase 1 protocol for patients with chemotherapy-refractory AML/MDS using GVHD prophylaxis with posttransplant cyclophosphamide followed by PD-1 inhibition with Nivolumab for consolidation. This protocol now offers a potentially curative treatment option for patients that otherwise would not meet criteria to undergo allogenic stem cell transplantation. 

Dr. Schade loves to bake all kinds of goodies including sourdough bread, bagels and New York style pizza. He also loves to go fishing with his kids. He loves the outdoors and can be found in the mountains hiking and skiing with his family. Dr. Schade is an enthusiastic fan of the Denver Nuggets and he of course is a big fan of European soccer.
