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).

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.

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.

Multiple myeloma (MM) relies on the bone marrow (BM) niche to progress to refractory disease. We found that beta blockers alter BM niche elements fostering MM growth and also reduce MM cell survival. Our objective is to elucidate the cellular and metabolic basis of how beta adrenergic signals impact the BM niche and MM progression. Knowledge of the prophylactic and therapeutic utility of beta blockers in MM will unravel new means to target neural niche remodeling fueling this fatal malignancy.

The goal of this project is to explore a novel immunologic therapeutic target for hematologic malignancies, SIGLEC15 (Sig15). The central hypothesis is that Sig15 is aberrantly expressed in malignant B cells, is released to attenuate immune responses and can be targeted therapeutically to promote immune responses to malignant hematopoietic cells. This work will accelerate therapeutic exploitation of the immune system for the treatment of leukemia and lymphoma by targeting Sig15.

SARS-Cov-2 infections may be prolonged in cancer patients and may enable intrahost development of virulent viral variants. Adoptive immunotherapy with virus-specific T-cells has been an effective treatment for refractory viral infections in immunocompromised patients following HSCT. We propose to study the functionality of coronavirus-specific T-cells (CSTs) from healthy donors, and utilize CSTs as preventative therapy for patients undergoing bone marrow transplant in a phase I study.
