Project Title: Capture and Analysis of Circulating Tumor Cells in Patients with Ewing Sarcoma

Innovation and Impact:

We propose a collaborative effort to develop a novel biomarker platform in patients with Ewing Sarcoma. The proposed studies will constitute an exciting first step towards the use of CTC in sarcoma, and will serve as the basis for a larger, federally-funded prospective trials aimed at establishing a new paradigm of CTC-guided molecularly-based, precision management in these diseases. As such, this proposal is uniquely suited to the Kure It mission and project criteria, as it “uses human subjects”, is “conducted by MD’s”, and is “focused on an underfunded cancer,” and will “lead to individualized therapeutic options for treatment”.

Project Title: Antibody Treatment of Prostate Cancer Expressing the Luteinizing Hormone Receptor (LHR)

Summary:

In the treatment of advanced PC, the response to androgen ablation therapy is often dramatic but transient. Over time, PC cells develop castration resistance. High intratumoral androgen levels and androgen receptor (AR) activity have been described in PC cells despite the low levels of circulating androgens resulting from androgen deprivation therapy (1-3). One potential explanation for these findings is de novo androgen synthesis. Recently, several groups have shown that PC cells are capable of producing testosterone directly from cholesterol (4-6). Up-regulation of genes and proteins encoding the necessary steroidogenic enzymes has been observed during castration resistant PC (CRPC) progression (6). Although up-regulation of steroidogenic enzymes has been described in CRPC, the regulation of this androgen synthesis is poorly understood.

Project Title: Targeting the P13KL-AKT-mTOR pathway in pediatric bone and soft tissue sarcomas: Translating a targeted therapeutic from bench to bedside

Summary:

Bone and soft tissue sarcomas are a heterogeneous group of malignancies that although rare are one of the most common cancers in children while having one of the worst prognoses overall. Furthermore, the research field of childhood sarcomas is one of the most underfunded in the cancer research field as a whole. Despite advances in current non-targeted chemotherapies the survival has plateaued for these aggressive malignancies, and we have made no progress in the treatment of metastatic sarcomas with an overall 5 year survival of about 20%. There is a dire need for development of new targeted therapeutics in these cancers, which would be applicable across the age groups from children to adults.

 Project Title: Therapeutically targeting oxidative stress in LKB1/STK11 deficient lung cancer

Summary:

Currently there are few effective, targeted therapies for the treatment of non-small cell lung cancer (NSCLC) and no effective strategies for the prevention of lung cancer. The LKB1/STK11 tumor suppressor gene is frequently mutated in both NSCLC, and to date there are no targeted therapies for patients with LKB1 mutations. LKB1 is a serine/threonine kinase that functions as a tumor suppressor regulating growth, metabolism and mitochondrial homeostasis through the adenosine monophosphate activated kinase (AMPK) and Unc1 like kinase 1 (ULK1) pathways. Recent studies have shown that loss of LKB1 predisposes NSCLC tumor cells and hematopoietic stem cells to mitochondrial defect resulting in high levels of reactive oxygen species (ROS) and my lab has recently discovered that the oxidative stress response (OSR) is highly unregulated in human and murine LKB1 deficient lung tumors across multiple tumor subtypes including ADC and SQCC leads to elevated levels of NAD(P)H:quinone oxidoreductase (NQ01), a key effector of the OSR.

Defining the RCC kinome for target discovery and individualized therapy

Dr. William Kim is an Assistant Professor of Medicine and Genetics in the Division of Hematology / Oncology as well as member of the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill.  Dr. Kim received his MD degree from Brown University and completed his medical residency and oncology fellowship at the Beth Israel Hospital and Dana-Farber Cancer Institute (Harvard Medical School) respectively.  A medical oncologist by training, Dr. Kim specializes in the treatment of patients with renal cell carcinoma (RCC) and runs a research laboratory focused on understanding the functional consequences of genetic and epigenetic events in RCC. 

"Approximately 65,000 new cases of renal cell carcinoma (RCC) occur annually in the US and its incidence is on the rise. While a number of kinase inhibitors are FDA approved for use in advanced RCC, their primary mode of action is believed to be antiangiogenic, via inhibition of the vascular endothelial growth factor receptor (VEGFR), or by inhibition of the mammalian target of rapamycin (mTOR). While sequencing of RCC has revealed inactivating mutations of tumor suppressor genes as well as genes involved in histone and chromatin modification, there is a paucity of kinase mutations. We have defined that there are three intrinsic kinomic subclasses of RCC and hypothesize that the RCC kinome, despite not being mutated, remains a tractable and actionable therapeutic target. Our work will define the activation state of the RCC kinome at the protein level and determine whether RCC kinomic subclass can predict therapeutic response to tailored kinase inhibition. The information garnered from this study should allow us to define a subset of kinases that are activated in RCC, differentiate kinomic subclasses of RCC, and lay the groundwork to begin to personalize kinase therapy based on the currently therapeutically actionable subset of the genome: the kinome."

HDM2/HDMX as a Therapeutic Target in Renal Cell Carcinoma

Dr. James W. Mier is a graduate of Indiana University School of Medicine. He was a Clinical Associate in the NCI Medicine Branch and Laboratory of Tumor Cell Biology, where he worked under the direction of Dr. Robert C. Gallo on the isolation and characterization of Interleukin-2 (IL-2). After leaving the NCI, he spent several years in the Hematology-Oncology Division at Tufts Medical Center in Boston, where he continued his work on IL-2 as a form of immunotherapy for patients with renal cell carcinoma and melanoma. In 1997, he moved to the Beth Israel Deaconess Medical Center, where he is currently an Associate Professor in the Division of Hematology-Oncology.  His laboratory research is currently focused on the various mechanisms by which renal cell carcinomas develop resistance to VEGF-targeted therapies. He is a Co-Leader of three projects in the DF/HCC Skin and Kidney Cancer SPOREs. 

"Tyrosine kinase inhibitors (TKIs) that target VEGF receptor signaling are among the drugs most frequently used in the first-line treatment of patients with renal cell carcinoma (RCC). Although treatment with these agents delays disease progression for several months in the majority of patients, it almost never induces complete responses and in those patients that respond initially, resistance inevitably develops after a few months of treatment. My laboratory has been focused on the mechanisms by which RCCs escape from VEGF-targeted treatment. One of the adaptations we have observed in RCC xenografts that have become resistant to sunitinib is the disabling of p53 function. Although the p53 gene is intact in the majority of RCC and the expression of p53-dependent genes is readily induced by treatment, these alterations in gene expression are not sustained during TKI treatment, despite the persistence of p53 levels. The concurrent administration of an HDM2 antagonist, however, results in persistent expression of p21 and other p53-dependent genes and sustained tumor non-progression. Treatment with sunitinib results in an influx of CD11b+/Gr-1+ myeloid-derived suppressor cells (MDSC), presumably due to the induction of the chemokine SDF-1. Both SDF-1 induction and the infiltration of tumor tissue by MDSC are suppressed by HDM2 antagonists. Finally, HDM2 antagonists suppress the expression of HIF-2a, the dominant oncoprotein in VHL-deficient RCC. Collectively, these data suggest that HDM2 antagonists might be ideal adjuncts to VEGF-targeted TKIs in the management of RCC. We hope to use the funds from Kure-It/AACR grant to further define the mechanisms by which HDM2 antagonists cooperate with TKIs to limit the growth and vascularity of RCC xenografts and ultimately, to apply our findings to the design of clinical trials that test the efficacy of these drug combinations in RCC patients."
