2019-2020 Duke-UNC Immunotherapy Training Program Postdoctoral Fellows

Joshua J. Bies, MD

Research Mentor: Barbara Savoldo, MD, PhD

Research Interests

My research interests are in the use of chimeric antigen receptor (CAR) T-cells in solid tumors, with a focus on pediatric malignancies and sarcomas. This involves confirming appropriate targets, and determining ways to overcome the challenges of solid tumors and immunotherapy such as tumor heterogeneity, antigen escape, and the immunosuppressive microenivornment.

William Cameron McManigle, MD

Research Mentor: Stefanie Sarantopoulos, MD, PhD

Research Interests

After graduating from the College of William & Mary, I completed a post-baccalaureate Intramural Research Training Award fellowship at the NIH. While at the NIH, I engaged in weekly rounds with the Immunotherapy Fellowship Training Program within the National Cancer Institute, where I was first introduced to concepts including targeted immunotherapy. I decided to learn how to conduct research devoted to improving both safety and efficacy of immunotherapies for cancer. As a medical student at Duke University, utilizing a mouse model of human adult bone marrow transplantation, I investigated the role of specific T-cell populations and associated cytokines in chronic graft-versus-host disease of the lung. After medical school, I remained at Duke to complete Internal Medicine residency and then sub-specialty training in Pulmonary and Critical Care Medicine. I have actively fostered a specific clinical interest in pulmonary complications of hematologic malignancy and cellular therapy and am caring for these patients in both the inpatient and outpatient clinic settings. The intersection of immunology, pulmonology and intensive care led me to join Dr. Sarantopoulos’ laboratory, to learn how to address pertinent, impactful questions using both human patient samples and mouse models, while obtaining in-depth training in allogeneic hematopoietic stem cell transplantation.

Nicholas Tschernia, MD

Research Mentor: Barbara Savoldo, MD, PhD & Benjamin Vincent, MD

Research Interests

My research focus: I am a Hematology / Oncology fellow at the University of North Carolina – Chapel Hill and have a deep rooted interest in the development of cellular therapy for hematologic and solid malignancies. My areas of active interest include: the expansion of our CAR-T cell therapy pipeline to include specific solid malignancies, such as nonseminomatous germ cell tumors, and a collaboration with our Immunocompromised Infectious Disease Division for a prospective biomarker trial evaluating the microbiome of CAR-T patients. In addition, I am working on a multi-institution collaborative endeavor through the Society for Immunotherapy of Cancer (SITC), called Project TimIOs, spanning 14 young investigators at 10 different institutions. This latter projects goal is to develop an unbiased database of immunotherapy outcomes in order to conduct both unsupervised and supervised analysis of existing RNA-seq datasets from pre-treatment biopsies. With the intent to identify immune gene expression signatures distinguishing pre-specified clinical outcomes.

2017-2018 Duke-UNC Immunotherapy Training Program Postdoctoral Fellows

Miranda Carper, PhD

Mentors: Barbara Savoldo, MD, PhD; Antonio Amelio, PhD

Research Interests
As a researcher, I am passionate about studying the molecular changes that occur during tumorigenesis with an interest towards developing targeted cancer therapies. The incidence of HPV-induced HNSCC is steadily increasing and is currently implicated in approximately 60 percent of all oropharyngeal carcinomas. Unfortunately, patients continue to suffer from high morbidity and mortality due to limited treatment options despite decades of research. While at UNC-CH under the advisement of Antonio Amelio, PhD, I have been characterizing a novel autochthonous genetically engineered mouse model (GEMM) for investigating HPV induced oral cancers since current models do not accurately recapitulate key features of this cancer. Specifically, I developed and validated a novel intra-lingual method of tamoxifen administration to ensure site-directed high-risk HPV16 E6 and E7 expression in the oropharyngeal mucosa using minimal tamoxifen. Currently, our recent discovery of immune cell infiltration by HPV16 E6 and E7 oncoproteins in our GEMM has prompted investigation into the mechanisms of immune suppression in the tumor microenvironment with hopes of developing adoptive T-cell therapies.

Alan Chen, PhD

Mentors: H. Kim Lyerly, MD

Research Interests

My goal is to develop immunotherapies to treat breast cancer. Therapeutic treatment of HER2+ (Human epidermal growth factor receptor 2) breast cancer with anti-HER2 monoclonal antibodies is part of the current standard of care. However, more than half of HER2+ breast cancer patients develop resistance against HER2-targeted antibodies and relapse during their first year. This reality highlights the need for the development of additional therapies. I am interested in the enhancing vaccines to elicit a stronger, more durable immune response against HER2+ tumors through the underutilized MHC-II pathway. I am also interested in exploring the synergisms between vaccination platforms and checkpoint inhibitors as a combinatory treatment for HER2+ breast cancers which have become resistant to the current standard of care immunotherapies.

Nancy Kren, PhD

Mentors: Shelton Earp, MD; Yuliya Pylayeva-Gupta, PhD

Research Interests
My overarching goal is to gain a better understanding of the role that immune response plays in the development and progression of pancreatic cancer. Specifically, I am interested in myeloid cell populations and how they contribute to the overwhelming immunosuppressive tumor microenvironment. Pancreatic tumors, as well as pre-invasive lesions, have significant immune cell infiltration, including tumor-associated macrophages and myeloid-derived suppressor cells (MDSCs), however, effector T-cells are rare. This increase in myeloid populations is associated with the lack of infiltrating effector T-cells. The underlying mechanisms that confer activation of immunosuppressive pathways in these myeloid populations in pancreatic cancer is not well understood. Currently, through a collaboration with the Earp lab, I am investigating how Mer and Tyro receptor tyrosine kinases, on monocytes and MDSCs, contribute to the immunosuppressive phenotype of myeloid cell populations. Mer and Tyro kinases can be activated by apoptotic material and act to polarize macrophages to a M2 or anti-inflammatory phenotype to prevent prolonged or chronic inflammation. In the context of pancreatic cancer, this fail-safe can contribute to the immunosuppressive tumor microenvironment. We are currently interrogating Mer and Tyro receptor tyrosine kinases in pancreatic cancer models utilizing genetic models as well as small molecule inhibitors.

Eben Lichtman, MD

Mentor: Gianpietro Dotti, MD

Research Interests
I am currently in my third year of training in the clinical hematology/oncology fellowship program at the University of North Carolina. My clinical interest is in multiple myeloma, and research interests focus on the development of cellular immunotherapies for patients with hematologic malignancies. In the lab, I work under the mentorship of Gianpietro Dotti, MD, to investigate potential chimeric antigen receptor T-cell based therapies for the treatment of acute myeloid leukemia. 

Alex Robeson, PhD

Mentor: Jonathan Serody, MD

Research Interests
My desire as a cancer biologist is to study the complex tumor microenvironment, with the ultimate goal to identify weaknesses and new therapeutic targets. In particular, I study B-cells that infiltrate breast tumors, with a focus on characterizing the B-cell receptor (BCR) repertoire. B-cell infiltration has been correlated with an improved prognosis in some breast cancer subtypes. Based on previous work, we believe that these B-cells have a direct, anti-tumor effect through BCR targeting. By employing single-cell genome and transcriptome sequencing, as well as bioinformatics tools developed by my predecessors, we aim to identify anti-tumor BCRs that can be turned into therapeutic agents as well as tumor-associated antigens that could serve as novel targets. Doing so could have a significant impact for breast cancer patients whose tumors are characterized by infiltrating lymphocytes, as is often the case for basal-like triple-negative tumors.
