Targeting aberrant epigenetic condensates in myeloid malignancies

Genetic changes of ASXL1 are very frequent in human blood cancers. We found that the altered forms of ASXL1 protein promote blood cancers through forming tiny liquid-like droplets in the cell. In this project, we aim to develop a method to specifically break these droplets to inhibit its activity in driving blood cancers.

Lower Dose Mitoxantrone for Venetoclax Resistant Acute Myeloid Leukemia

Venetoclax-based regimens are the standard of care for many patients with acute myeloid leukemia (AML) and are highly active therapeutic strategies for this challenging disease. However, some patients do not respond, and most patients who do respond will relapse. We have discovered that resistance to venetoclax may be mediated by the movement patterns of calcium throughout a cell. Furthermore, we have found that mitoxantrone, a conventional chemotherapy agent, can interrupt these calcium fluctuations at very low doses. Therefore we have proposed a clinical trial using lower-dose mitoxantrone for AML patients whose disease has resistance to venetoclax-based regimens.

Targeting Myeloid Malignancies through IRAK4 Synthetic Lethality Dependencies

Based on our preliminary data, we hypothesize that IRAK4 inhibition leads to LSPC reprogramming in MDS and AML. Aim 1 will evaluate the mechanism by which IRAK4 inhibition leads to LSPC reprogramming in cell lines, mice, and PDX samples. Aim 2 will concentrate on understanding of how IRAK4 inhibition creates synthetic lethal dependencies with the CELMoD CC-885 and how neosubstrates of CC-885 mediate the synergy upon IRAK4 inhibition in leukemic cells.

KT1, a novel NK trispecific antibody for the treatment of AML and MDS

New treatments for AML and MDS are urgently needed. We have developed and performed preliminary testing of a novel, patent-protected, trispecific NK cell engager named KT1 which targets AML blasts and leukemia stem cells (LSCs) expressing CD33 and CD123 for elimination by effector cells that express CD16a/b. We plan to test the ability of KT1 to release cytokines and facilitate killing of CD33- and/or CD123-expressing targets by different types of CD16a/b-positive effector cell populations including resting natural killer (NK) cells, cytokine-induced memory-like (ML) NK cells, gamma/delta T cells, and macrophages both in vitro and in leukemic mice. We anticipate that a future treatment of AML and/or MDS with KT1 combined with a donor leukocyte transfer of allogeneic NK, ML NK, or gamma/delta T cells will have excellent therapeutic efficacy and a far better safety profile than many currently studied immunotherapies being tested in patients with AML or MDS.

Targeting Leukemia Stem Cells with the Novel Antibody Drug Conjugate

To improve the cure rate of patients suffering from acute myeloid leukemia (AML), our study aims to target resistant leukemia stem cells by developing an 'antibody-drug conjugate' (ADC) against CD99, a protein expressed on these cells. Initial tests of two ADC versions have shown promise in combating AML. Our next steps involve refining the anti-CD99 antibody, identifying the optimal drug for conjugation, and testing the ADC on patient-derived leukemia models. Completing these objectives will pave the way for a phase 1 clinical trial, offering a potentially transformative treatment for AML.

211Astatine-CD123 Radioimmunotherapy for Cancer (Stem) Cell-Directed Treatment of Acute Leukemia

Because acute leukemias are very sensitive to radiation, radioisotopes are ideal payloads to arm antibodies against these difficult-to-cure, aggressive blood cancers. Here, we will develop fully human anti-CD123 antibodies carrying the highly potent alpha-emitter astatine-211 (211At) as a new therapy for acute leukemia. CD123 is broadly displayed on acute leukemia cells in most patients and overexpressed on leukemic stem cells but is only found on a small subset of normal blood cells, enabling the use of 211At-CD123 radioimmunotherapy in the transplant and non-transplant setting with limited toxicities to normal tissues.

Towards clinical testing of epitope editing to enable novel adoptive immunotherapies

Innovations in gene engineering have made it possible to reprogram immune cells to attack specific targets on cancer cells, allowing the first adoptive cellular immunotherapies, known as CAR T cells, to be approved by the FDA for the treatment B lymphoblastic leukemia. A similar approach is currently under development for AML, but in contrast to B-ALL, there is no leukemia-specific target which would be amenable to targeting by immune cells without incurring severe adverse effects. Here, we aim to modify normal bone marrow stem cells used for allogeneic transplantation to make them resistant to CAR-T cells, thus enabling targeting proteins essential for tumor survival without the risk of severe toxicity on the healthy tissue counterpart.

Multi-modal Immunotherapeutic Targeting of AML-restricted Targets in Infants and Children

Advances in understanding and management of AML in children has been stagnant for decades. Observed improvements in survival are more directly linked to improvements in supportive care or risk identification rather than advances in therapeutics. Excitement around FDA approval of two new IDH1/2 inhibitors did not reach the pediatric oncology community given paucity or absence of such mutations in children. This also highlights the stark differences between AML in older adults and that in younger patients. Thus, “trickle down therapeutics” where therapies that are developed in older adults are used effectively in children is a flawed concept. Discoveries and therapeutic development in younger patients must be prioritized if meaningful advances are to be made in curing AML in younger patients. Given that AML in children is not a priority for the pharmaceutical companies, alternate mechanisms for advancing therapeutics in children and young adults should be implemented.

Targeting Epigenetics in Myeloid Malignancies

We have a highly collaborative team of investigators, whose goal is to develop novel therapeutic approaches to MDS and AML as well as to improve current therapies for these diseases based on a detailed understanding of how epigenetic dysregulation contributes to myeloid neoplasia. We are focusing on the clonal MDS or AML cell and on the bone marrow microenvironment (BMME), including immune cells that could contribute to or limit the progression of these disorders. Our Center brings together chemists, biochemists, cellular biologists and molecular biologists, who are supported by three core facilities, including an Administrative core, an Epigenomics core and a Bioinformatics and Big data sharing core. To advance our Center’s ability to implement personalized therapies for patients with myeloid malignancies, we have generated and will generate novel reagents, and utilize state-of-the-art in vitro and in vivo assays to identify key modulators of drug sensitivity or resistance. We will focus on so-called “epigenetic-focused” therapy, realizing that many of the enzymes that regulate epigenetic control of cell fate, influence signal transduction pathways, RNA splicing events, and the activity of key cellular proteins, such as BCL2 family members and p53.

The genetic mutations that underlie myeloid malignancies have been identified, and we and others have generated mouse models that have pinpointed the role that these genes and their mutations play in normal and malignant hematopoiesis. Our institutions have biospecimen banks with large numbers of MDS and AML samples, and active clinical trial portfolios, that have led to FDA approval of a variety of novel agents, including IDH1/2 inhibitors. The next step in delineating the pathogenesis and Achilles’ heel of these disorders is to better define the role of epigenetic abnormalities play in disease initiation and progression, and to define how targeting LSD1, the CoREST complex, PRMT5 and inflammation signals may advance current treatment strategies (e.g. VEN/AZA), and to enhance the activity of promising agents currently under investigation (menin inhibitors, etc.). Identifying the dependencies and vulnerabilities created by genetic or epigenetic abnormalities will allow us to more rationally advance the treatment of myeloid malignancies, a disease focus where headway is beginning to be made.

Defining the crosstalk between different epigenetic regulators, and how they affect cellular and extracellular processes other than histone proteins, may identify unique sensitivities that can increase the therapeutic index for novel, epigenetic-focused treatments, and identify potentially synthetic-lethal combination therapies. The individual projects in our Center, cover three key aspects of gene regulation and chromatin structure. Project 1 is focused on the LSD1 demethylase, which plays a role in myeloid differentiation, Project 2 is focused on the role of PRMT5 in regulating LSC self-renewal, proliferation and survival, and the expression of potential immunogens, and Project 3 is focused on the interaction between the BMME and the epigenome in mediating sensitivity to epigenetic agents in CMML and MDS. Thus, our center will span the continuum from basic mechanisms of disease initiation and progression, to clinical issues related to therapeutic sensitivity vs. resistance.

Ramin Shiekhattar first discovered that MAO inhibitor antidepressants such as tranylcypromine (TCP), can inhibit the LSD1 demethylase. This finding led to a recently published clinical trial of AZA + TCP in MDS and AML patients led by Justin Watts, and to a new clinical program, that will be continued at Sylvester and MSKCC. They will work with Phil Cole, who founded a biotech company in 2011 that is synthesizing novel epigenetic-focused therapies, to examine how targeting the CoREST complex can synergize with clinically available MDS/ AML cells differentiation- or apoptosis-inducing agents. Several lead compounds are now being tested in the Shiekhattar and Nimer labs.

Omar Abdel-Wahab and Stephen Nimer have discovered several oncogenic functions of PRMT5, an arginine methyltransferase targeted by several small molecule inhibitors that are now in clinical trials for MDS or AML patients at Sylvester and MSKCC. They will work with Luisa Cimmino to exploit their work implicating PRMT5 in regulating homologous recombination, RNA splicing and p53 function. Maria Figueroa has extensively studied predictors of the clinical response to DNA hypomethylating agents (HMA) and has identified critical mediators of HMA resistance originating in the BMME. She will work with Ross Levine, a leader in delineating the molecular pathogenesis of hematologic malignancies, to evaluate how signals from the BMME impact the responsiveness of MDS and CMML cells to HMA combinations as well as how to overcome primary resistance to HMA by targeting key signals in the niche.

Three Cores will enable the efficient completion of our collaborative studies. Core A, the Administrative Core, will be housed at UM; it will provide infrastructure support, to optimize interactions between the various labs represented here, handle all financial and reporting aspects of the grant, assist with the SCOR site visit and the annual meeting of the Center, and maintain regulatory compliance for the Center (e.g. assuring access to bio-specimens, handling IRB and IACUC approvals, etc.). Both UM and MSKCC continue to collect MDS/AML/MPN bio-specimens. Core B, the Epigenomics Core, led by Sion Williams and Lluis Morey, will perform various NGS-based assays to assess genome-wide changes in gene expression, DNA methylation, and histone post-translational modifications. Core C, the Bioinformatics and Big Data Core, led by Stephan Schürer, will provide bioinformatics support and ensure complete and efficient sharing of data for all three projects in the SCOR.

Leveraging dysregulated signaling networks for therapeutic benefit in myeloproliferative neoplasms

The objective of this project is to decipher mechanisms driving transformation of myeloproliferative neoplasms (MPNs) to secondary acute leukemia (sAML). We have identified increased expression of DUSP6 and RSK1 in sAML patient cells. Genetic/pharmacologic targeting suggest a role for DUSP6 and RSK1 in MPN development. We thus propose studies to determine how DUSP6 and RSK1 contribute to MPN pathogenesis, and to evaluate the therapeutic potential of DUSP6 and/or RSK1 inhibition for MPN patients.

Pan-heme CAR: Anti-CD38 CAR T cells for myeloid, lymphoid and plasma cell malignancies

Our SCOR team has a razor-sharp focus on an exciting new treatment modality for blood cancers: chimeric antigen receptor (CAR) T cells. T cells can be trained to target cancer cells by genetic modification. In fact, previous support from the Leukemia & Lymphoma Society allowed us to successfully develop CAR T cells targeted to CD19, a pan-B cell marker. This treatment, generically called CART-19, was approved by the FDA in 2017 for the treatment of B-cell acute lymphoid leukemia (B-ALL) and in 2018 for some non-Hodgkin lymphoma (NHL), with promising results in other B cell malignancies such as chronic lymphocytic leukemia (CLL). Thus, the development of a single therapy for a single disease (initially, CLL) paid handsome dividends when translated to a broader range of CD19-expressing malignancies (ALL, NHL).

Targeting Leukemia Stem Cells in the Clinical Setting: The Development of A Comprehensive Program

My focus is to develop a program in which novel therapies targeting leukemia stem cells (LSCs) are tested in clinical trials. This is achieved via partnership with laboratory-based colleagues who identify vulnerabilities in LSCs. Once recognized, we find or develop drugs to exploit these weaknesses through clinical trials for acute myeloid leukemia patients. The goal is to bring forward new therapies that result in deep and durable responses, which also have the potential to cure this disease.

Targeting cathepsin G in acute myeloid leukemia

We developed a chimeric antigen receptor (CAR) targeting an epitope of the myeloid associated antigen cathepsin G that is processed and presented in the contest of the MHC complex in myeloid leukemic cells. T cells expressing the cathepsin G specific CAR (CG1.CAR) recognize HLA-A2+ myeloid target cells expressing cathepsin G. We intend to study efficacy and safety of CG1.CAR-T cells in preclinical models in preparation of a phase I clinical study in patients with relapsed/refractory AML.

A precision-based all-oral combination of venetoclax, oral decitabine, and IDH1/2 targeted inhibition for patients with IDH1 or IDH2 mutated AML

My ultimate goal is to develop more effective, better tolerated, and individualized treatment for patients with AML. This project focuses on AML patients with IDH1 or IDH2 mutations, with a clinical trial evaluating a combination of three agents which are effective in IDH-mutated AML. While these therapies are not curative on their own, my hope is that this combination will lead to a practice changing all-oral, outpatient, and well-tolerated curative strategy for patients with IDH-mutated AML.

Aberrant LZTR1 and RIT1 signaling as a driver of clonal hematopoietic disorders

Our research focuses on a novel mechanism of RAS protein regulation via the protein LZTR1, which is altered in leukemia and hinders the effectiveness of leukemia therapies. We will utilize mouse models and functional genomic studies to uncover how altered RAS degradation drives leukemia and identify novel drug targets. This effort will help us identify the clinical impact of alterations in this novel RAS pathway in patients and potential means to improve leukemia treatment.

Discovery of Aging-Driven Mechanisms Causing Clonal Hematopoiesis (CH) and its Progression to Hematological Malignancy

My research focuses on why and how risk of acute myeloid leukemia (AML) increases with aging. Studying naturally aged mouse models in combination with mice engineered to express mutations commonly found in human blood stem cells with aging, we are investigating whether certain inflammatory factors that increase during aging increase the risk of leukemia. My goal is to identify biomarkers to assess risk of AML development in aging individuals and define new therapeutic targets to prevent AML.

Targeting non-genetic mechanisms of therapeutic resistance in Acute Myeloid Leukaemia

Drug resistance in AML can develop via a non-genetic process which remains poorly understood. Using our novel cellular barcoding technology that can trace the growth of thousands of cancer cells, our research will identify genes that are switched on or off in AML cells that lead to drug resistance and relapse. This work will reveal the factors underpinning non-genetic drug resistance that may be targeted with new drugs to prevent relapse and ultimately improve quality of life and survival.
