Clinical outcome of high-risk Myelodysplastic Syndrome (MDS) and AML with mutant (mt) RUNX1 is relatively poor. Supported by our preclinical data, we propose a Phase Ib clinical trial of omacetaxine mepisuccinate (OM) and venetoclax along with correlative science studies in patients with relapsed MDS or AML exhibiting mtRUNX1. Studies proposed will also determine pre-clinical activity of novel, OM-based combinations against mtRUNX1-expressing, patient-derived, pre-treatment AML cells.

We will enroll transplant-eligible patients with intermediate-risk AML, and define mutation clearance after recovery from induction using deep exome sequencing. Patients who clear all mutations will be consolidated with chemotherapy only (HiDAC). Patients who fail to clear all mutations will be offered an allogeneic transplant. This prospective study may improve outcomes for intermediate-risk patients by more precisely using transplantation in first remission.

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.

Mutations in the spliceosome gene SF3B1 are common in myeloid malignancies, but they are currently untargetable. Our previous work has shown that SF3B1 mutations reprogram energy metabolism and create vulnerability to restriction of the nonessential amino acid serine. Here we propose a preclinical project studying PEGylated cystathioinine beta synthase (pCBS), a recombinant enzyme that catabolizes serine, as a treatment for SF3B1-mutant myeloid malignancies.

Novel therapies are needed for ~40% of Diffuse Large B-Cell Lymphoma (DLBCL) patients who do not respond to the standard immune-chemotherapy regimen. Repurposing for DLBCL FDA-approved drugs and other targeted compounds in clinical development may offer a fast-track route to the clinic. Toward this end, we identified inhibitors of the enzyme NAMPT as active against a subset of DLBCL. The goal of this proposal is to thoroughly develop the pre-clinical rationale for NAMPT inhibition against DLBCL.

We propose laboratory and clinical studies to understand the mechanisms of anti-myeloma activity of tasquinimod, a small molecule inhibitor of S100A9. This proposal is part of an ongoing collaboration between Dr. Yulia Nefedova, whose laboratory studies the myeloma bone marrow microenvironment and its immunosuppressive effects, and Dr. Dan Vogl, whose clinical and translational research program focuses on novel therapies for relapsed and refractory myeloma.

STAT3 is over-expressed in highly purified leukemic stem & progenitor cells and its expression is associated with a worse prognosis. Inhibition of STAT3 by an anitsense oligonucleotide AZD9150 leads to decreased viability of leukemic stem cells in in vitro & in vivo models. In the proposed studies, we will comprehensively examine the role of STAT3 in AML stem cell dynamics, identify the mechanisms of its actions and determine the efficacy of clinically available STAT3 inhibitors.

Myeloproliferative neoplasms (MPNs) carry JAK2(V617F), MPL(W515L) and mutations in calreticulin (CALRmut) often accompanied by mutations in TET2, ASXL1, DNMT3A, EZH2, and other genes. We will develop a strategy based on gene mutation profiling to identify MPNs displaying specific defects in DNA repair. These defects will be then explored by specific DNA repair inhibitors to eliminate quiescent and proliferating MPN stem and progenitor cells without affecting normal cells and tissues.

Project Term: July 1, 2021 - June 30, 2024

We will test if Gene Expression and Mutation Analysis (GEMA) could be applied as personalized medicine tool to identify individual patients with AML displaying specific preferences for repairing spontaneous and drug-induced DNA damage. These preferences will predispose leukemia stem and progenitor cells to synthetic lethality triggered by already approved as well as novel DNA repair inhibitors.

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.

This proposal aims to understand the molecular mechanisms underlying response to AZA therapy in MDS, as a basis for developing more effective therapies. A ribonucleotide, AZA’s effects on RNA remain unknown. Here, we will investigate the impact of in vivo AZA therapy on RNA alternative splicing and DNA demethylation in MDS patients. Secondly, we will investigate whether AZA treatment exposes neoepitopes in the dysplastic cells of patients, which could be exploited for cancer immunotherapy in MDS

The oncoprotein eIF4E is dysregulated in many cancers including AML. We show that eIF4E drives production of the glycosaminoglycan hyaluronan (HA). Further, HA elevation alters the surface architecture of high-eIF4E AML cells and this is required for eIF4E’s oncogenic activity. We will explore HA’s involvement in AML and the efficacy of depleting HA in patients using hyaluronidase in a Phase I trial in AML.
