Vanderbilt-Ingram Cancer Center (VICC) is the only NCI designated cancer center that serves both adult and pediatric populations in TN, one of the highest cancer-mortality states in the country. In fact, TN rural dwellers encompass about 30-50% of the states’ population, many with lower per-capita income and high school graduation rates. Influencing cancer care by facilitating underserved and minority populations to access therapeutic clinical trials as well as those focused on screening and prevention strategies remains a cornerstone objective. The Vanderbilt Health Affiliated Network (VHAN) serves as the largest provider for an organized network of hospitals, clinics, and health systems across TN. This network encompasses 12 health systems and 61 hospitals. Within VHAN, the VICC has had a formal affiliation with Baptist Memorial Healthcare Corporation (BMHCC) since 2012. BMHCC is affiliated with 22 hospitals and provides care for 8000 new cancer patients (pts) annually covering 111 counties totaling 4.3 million people. This includes 44% of the 252 counties and parishes in the Delta Regional Authority, congressionally acknowledged as the most indigent population in the US. The primary objective of the VICC community center affiliation with BMHCC is to enhance the regional level of cancer care and to advance cancer research efforts. VICC has provided guidance on a regular basis to assist BMHCC in the establishment and implementation of the Minority and Underserved National Cancer Institute Community Oncology Research Program (NCORP) grant as a successful and sustainable program. BMHCC has become amongst the top recruitment sites for NCORP, with steady growth in the proportion of rural pts seen across the health system. VICC continues to be a resource for BMHCC on providing consultations, training, and best practices for specialized services such as clinical research, radiation oncology, cancer screening, stem cell transplantation and community engagement.

We have long standing experience in the field of HCL research. The aim of this research proposal is to characterize HCL on single cell level across multiple layers to uncover interactions of HCL with its microenvironment, which supports HCL cell survival. We will further explore metabolic and functional dependencies of primary HCL cells, and we hypothesize that their attenuation compromises HCL cell survival. Finally, we aim to pharmacologically disrupt these pro-survival pathways in HCL cells.

My ultimate goal is to develop more effective, better tolerated, and individualized treatment for patients with AML. This project focuses on AML patients with IDH1 or IDH2 mutations, with a clinical trial evaluating a combination of three agents which are effective in IDH-mutated AML. While these therapies are not curative on their own, my hope is that this combination will lead to a practice changing all-oral, outpatient, and well-tolerated curative strategy for patients with IDH-mutated AML.

Dr. Madhav Dhodapkar, M.D., of Winship Cancer Institute of Emory University, Atlanta, leads a multi-institutional, multi-disciplinary LLS Specialized Center of Research team focused on advancing new immunotherapies for patients with multiple myeloma. Their goal is to improve the effectiveness of CAR T-cell immunotherapy, which engineers the patient’s T cells to find and kill cancer cells. The CAR-T they are studying targets a protein called BCMA found on the surface of all myeloma cells. BCMA-targeting therapies are showing tremendous promise for treating myeloma patients in clinical trials, but many patients eventually relapse. Dr. Dhodapkar’s group is working to understand the mechanisms that cause some patients to be resistant to the treatment. They are also investigating another type of immunotherapy that relies on natural killer T cells. His team includes researchers at Emory as well as Fred Hutchinson Cancer Center in Seattle.

In this proposal, the Choi lab is investigating mechanisms that underlie aggressive forms of T cell lymphoma. They have found a gene mutation that is found exclusively in aggressive subtypes. There is a gene that encodes for PD1 that suppresses tumor progression. In a subset of T cell lymphomas, this gene is lost or inactivated, leading to increased tumor progression and aggressiveness. Here they propose three complementary approaches to understand how this gene constrains T cell lymphomas and importantly, they are now proposing to leverage this information to generate novel treatments for the patients who need it most. 

Pediatric AML is a disease with poor outcomes and a need for improved therapeutic options. Pediatric AML is characterized by diverse lesions that often do not overlap with adult AML, which therefore means therapeutic development must be done using pediatric AML models. Recent advances in patient derived xenograft (PDX) modeling have made possible the successful development of PDX models of diverse pediatric AML subtypes.

Dr Tasian’s scientific passion is successful development of precision medicine therapies for high-risk childhood leukemia. Her translational laboratory research program focuses upon investigation of kinase inhibitors and chimeric antigen receptor (CAR) T cell immunotherapies in childhood ALL and AML using primary patient specimens and patient-derived xenograft models. Through her laboratory and clinical research, she aspires to improve cure rates and minimize toxicities for children with leukemia.

Hairy cell leukemia (HCL) is very sensitive to chemotherapy, whose toxicity to the bone marrow and the immune system is however concerning. We have established vemurafenib plus rituximab as a very effective chemotherapy-free regimen in relapsed/refractory HCL (NEJM, in press). Here, we will test it in a clinical trial against a chemotherapy-based standard of care represented by cladribine plus rituximab, aiming at lower toxicity and similar efficacy.

My research focuses on why and how risk of acute myeloid leukemia (AML) increases with aging. Studying naturally aged mouse models in combination with mice engineered to express mutations commonly found in human blood stem cells with aging, we are investigating whether certain inflammatory factors that increase during aging increase the risk of leukemia. My goal is to identify biomarkers to assess risk of AML development in aging individuals and define new therapeutic targets to prevent AML.
