Christine L Hann, completed her MD and Ph.D. at Jefferson Medical College/Thomas Jefferson University follwed by an internal medicine residency at the University of Chicago Hospitals. Following a fellowship at Johns Hopkins University in Hematology and Oncology, Dr. Hann joined the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center as a member of the Upper Aerodigestive Cancer Program and sees patients with non-small cell and small cell lung cancer.Dr. Hann's research focus is on developing novel therapeutics for lung cancer, particularly small cell lung cancer (SCLC) and neuroendocrine tumors (NETs) such as carcinoid tumors of the lung. As a faculty member she is involved in both clinical and laboratory research.Specific research projects include:1) Studying mechanisms of resistant to small molecule inhibitors of the antiapoptotic protein, BCL-2 using patient-derived xenograft models. Her preclinical work has led to an NCI-sponsored Phase 1/2 clinical trial combining a BCL-2 inhibitor with a TORC1/2 inhibitors which is currently underway (NCT03366103).2) Preclinical evaluation of various therapeutics including epigenetic modulators (LSD1 inhibitors) and nanoliposome chemotherapy in SCLC PDXs;3) Modeling and characterizing chemoradiotherapy resistance in preclinical models of SCLC. She, along with Dr. Luigi Marchionni in Biostatistics and Dr. Phuoc Tran in the Department of Radiation Oncology, were recently awarded a 5-year NCI-sponsored U01 grant to study mechanisms of chemoradiation resistance in SCLC. Dr. Hann is PI of several trials in SCLC and NSCLC and is leading investigator-initiated clinical trials in SCLC and NETs.
