Gainesville, FloridaAdenylate Kinase 2-A Novel Therapeutic Target in Multiple Myeloma
We identified the adenine nucleotide regulator AK2 as a selective dependency in multiple myeloma (MM) that is more essential for survival of MM cells overexpressing the histone methyltransferase NSD2. Here, we propose a series of experiments to understand the role of AK2 in MM cell fitness and response to existing therapies and elucidate the molecular basis of the increased dependence on AK2 driven by NSD2 overexpression. This study will elucidate the effects of AK2 inhibition in MM and will credential the enzyme as a therapeutic target.

Vancouver, British ColumbiaTargeting aberrant non-canonical NF-κB pathway activation in B-cell lymphomas
The impact of biological heterogeneity on treatment outcomes is evidenced by a large proportion of lymphoma patients who experience relapsed/refractory disease. To address this knowledge gap, we sequenced primary lymphoma samples and found recurrent mutations in the non-canonical NF-kB pathway (NC NF-kB) and uncovered the NIK kinase as a targetable candidate. Our next steps focus on using advanced genetic modelling approaches to provide preclinical rationale for targeting NC NF-kB in lymphomas.

Few treatment options are available for T cell leukemias and lymphomas, collectively called T cell cancers that affect ~100,000 patients worldwide each year. The current proposal will generate new antibodies attached to drugs and toxins that kill the T cell cancers. Importantly, the antibodies will preserve enough healthy T cells to maintain a functioning immune system. These modified antibodies may improve patient outcome and limit side effects associated with traditional chemotherapies.

The mitogen-activated protein kinase (MAPK) pathway is activated in high-risk leukemia and is a hallmark of resistance to therapies. This project uses patient-derived xenograft models of relapsed pediatric ALL and AML with activated RAS/MAPK to test whether clinically relevant MAPK mutations activate the VAV3/RAC pathway and if pharmacological inhibition of that pathway by a small molecule we developed synergizes with a MAPK-inhibitor to provide a new treatment strategy for RAS-driven leukemia.

The B-cell kinase SYK and its T-cell homolog ZAP70 have almost identical functions but are strictly segregated to B- and T-cells. We recently discovered that B-cell malignancies frequently coexpress ZAP70 and that only SYK but not ZAP70 can trigger negative B-cell selection and cell death. Here we test the hypothesis that ZAP70 enables malignant B-cell transformation, test pharmacological SYK-hyperactivation and validate ZAP70 as biomarker of patients who benefit from this approach.

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.

In a non-human primate model, a single dose of an antibody targeting the Notch ligand DLL4 markedly increased GVHD-free survival as a single agent. Building on the highly conserved role of Notch signaling in GVHD, we propose to identify and characterize the most promising combination therapeutic strategies for clinical translation to patients.

Incorporation of circulating tumor DNA (ctDNA) monitoring into clinical trials of classic Hodgkin lymphoma (cHL), which is the primary objective of this proposal, will allow to: i) precisely define ctDNA accuracy in anticipating disease course; and ii) test if ctDNA results can be used to guide treatment decisions. The project results can translate ctDNA monitoring as a routine response assessment tool for cHL.

This project will generate optimized single-chain antibodies (nanobodies) against HVEM and BTLA, two cell receptors that are misregulated in ~75% of follicular lymphomas. We will select for nanobodies that inhibit lymphoma tumor growth through restoration of HVEM or BTLA activity. We will further engineer lymphoma-targeted CAR-T cells, which have shown anti-tumor activity in other malignancies, to secrete these anti-HVEM or anti-BTLA nanobodies, in an alternative combination therapy approach.

Niclosamide is an FDA approved anti-parasitic drug that is well tolerated in adults and children. AML cells are sensitive to niclosamide, act synergistically with chemotherapy in vitro, and inhibit the proliferation of primary AML stem cells in vivo. We propose to examine the effects of niclosamide in combination with chemotherapy in animal models of AML and study the mechanism of action of niclosamide in AML cells in anticipation of a clinical trial in children with relapsed AML.

Atlanta, GeorgiaDeciphering the metabolic basis for t(11;14) multiple myeloma venetoclax sensitivity
The BCL-2 antagonist venetoclax is highly cytotoxic in a subset of t(11;14) multiple myeloma (MM). In investigating the metabolic basis for the sensitivity of t(11;14) MM to venetoclax, we determined that sensitive cells exhibit significantly reduced succinate ubiquinone reductase (SQR) activity. In addition, inhibition of SQR sensitizes resistant MM to venetoclax. Our proposal seeks to investigate SQR as a diagnostic and therapeutic target to broaden the application of this potent BH3 mimetic.

Nearly half of patients with diffuse large B-cell lymphoma (DLBCL), ultimately fail current therapies and die from their disease. Selective targeting of cyclin-dependent kinase 9 (CDK9) is a promising strategy, as evidenced by potent anti-tumor effects in preclinical models of DLBCL. Yet tumors evade therapy by developing resistance. This proposal seeks to both elucidate and circumvent the oncogenic events underlying this resistance in order to offer novel therapeutic approaches to treat DLBCL.

Refractory pediatric B- and T- lymphoid cancers exhibit hyperactivation of MYC and its downstream pathways. Experimentally, MYC inactivation sustains tumor regression. However, MYC’s requirement in normal B/T-cells has hampered the development of MYC inhibitors. Recently, we showed that MYC-High B/T-Lymphoid Neoplasms (B/T-MLN) evade Natural Killer (NK) cell surveillance. Hence, we propose to develop targeted off-the-shelf NK therapies as an alternative to MYC inhibition for treating B/T-MLN.
