This proposal seeks to develop for the first time in humans a novel CD5 knocked out (KO) anti-CD5 chimeric antigen receptor T cell (CART) product for patients with relapsed or refractory T-cell lymphomas. In Aim#1, we will generate and test a clinical-grade CD5 KO CART5 product, and in Aim#2, we will perform a phase I clinical trial. This project is highly relevant to those parts of the LLS's mission that pertain to the development of personalized and novel therapies for cancer treatment.

Our team is the first to develop a polyomic pediatric cGvHD biomarker test for assessing the risk of developing cGvHD. A cooperative adult phase III clinical trial, CTTC1901, between Canada and Australia, focused on decreasing cGvHD (N=350 patients), offers an ideal opportunity to validate adult cGvHD biomarkers. This proposal will utilize the pediatric polyomic approach to validate a cGvHD risk assignment and diagnostic algorithm in adult hematopoietic stem cell transplant (HSCT).

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive malignancy that is exceptionally difficult to cure after relapse. We have previously shown that T-ALL expresses high levels of the enzyme AKR1C3, leading to clinical trials of AKR1C3-activated prodrugs. This project will focus on identifying the determinants of responses to AKR1C3-activated prodrugs in T-ALL and optimizing the use of a second generation AKR1C3-activated prodrug, SN36008, in T-ALL patient-derived xenografts.

In recent work of our collaborating labs, the protein acetyltransferases P300 and CBP emerged as potent and preferential dependencies for multiple myeloma (MM) based on genetic depletion, catalytic inhibition or chemical degradation studies. Our current project will define distinct vs. redundant molecular and biological functions of P300/CBP in MM, identify the mechanisms of resistance to their inhibition/degradation and exploit these findings to develop new therapeutic modalities to treat MM.

Despite the promise of CAR-T cell immunotherapy for patients with lymphoma and multiple myeloma, a significant proportion of patients fail to respond or relapse following treatment. This project will focus on the clinical translation of a new treatment designed to improve durable response rates by combining CAR-T cell therapy with a new class of anticancer drugs called SMAC-mimetics. The results will provide the evidence base to drive a first-in-human clinical trial of this combination strategy.

Evolving insights into the B cell-restricted FCRL1 surface protein reveal that it integrates with critical signaling pathways and is a promising immunotherapeutic target in CLL. Based on preclinical evaluation of novel FCRL1 monoclonal antibodies, we propose developing chimeric antigen receptor (CAR) T cells for targeting in unique mouse models and patient-derived cells. The results will form the basis for strategic drug development and clinical testing in CLL and related B cell malignancies.

The proposed studies will identify alterations in hematopoietic regulation that predict for risk for therapy-related myeloid neoplasm (TMN) and improve understanding of disease evolution to guide strategies to prevent TMN in patients receiving autologous hematopoietic cell transplantation (aHCT) for lymphoma. They will investigate alterations in hematopoietic function in peripheral blood stem cell used for aHCT, and serial evolution of hematopoietic defects leading to development of TMN.

Myelofibrosis is a severe myeloproliferative neoplasm with no known cure. We have obtained unique insights into the underlying mechanisms responsible for the emergence of myelofibrosis and designed new approaches to selectively control it. By combining our mutation-specific isolation methods with single cell sequencing, we will identify myelofibrosis-initiating stem cell populations, demonstrate efficacy of stem cell targeting and enumerate residual normal stem cells to inform a Phase I/II trial.

Multiple myeloma is an incurable blood cancer complicated by bone diseases and compromised immune system. Our work indicated that checkpoint inhibitor PD-1H(VISTA) functions as the MMP-13 receptor, and the MMP-13/PD-1H signaling axis plays a critical role in multiple myeloma induced bone disease and immunosuppression. Therefore, immunotherapy targeting the novel MMP-13/PD-1H interaction module represents a novel approach to cure this devastating cancer.

Extremely low dose radiation can improve blood cancer outcomes. But the mechanisms of how sublethal radiation (SRT) affects tumors, the microenvironment and immune system remain unclear. We envision a broad, nuanced role for SRT with benefits across diverse clinical situations and propose 3 clinical trials with deep translational components. Each can be paradigm-changing, but are thematically unified to improve mechanistic understanding of how such exceptionally small doses might offer so much.

Leukemia patients with chromosomal translocations of the Nucleoporin (NUP98) gene suffer from very poor prognosis. In this project we will identify new treatment for these patients by combining menin inhibitor with FDA approved drugs. We will evaluate effectiveness, mechanism of action and biomarkers of treatment response to these combinations in advanced pre-clinical models of NUP98 leukemia. We expect these studies will lead to future clinical trials in AML patients with NUP98 translocations.

The present project will investigate the ability of quantitative immune precipitation mass spectrometry (QIP-MS) to anticipate relapsed or progressive disease in peripheral blood samples from patients with multiple myeloma. In the context of the GEM2014MAIN trial (lenalidomide and dexamethasone plus or minus ixazomib as maintenance), we will assess the presence of disease by QIP-MS in parallel with conventional methods in serum and next generation flow in bone marrow samples.
