We have identified the multi-domain protein DCAF1 as a genetic dependency in multiple myeloma and developed a series of potent on-target DCAF1 inhibitors that have a unique mode of action compared with existing therapies. In this proposal we will continue the detailed molecular characterization of our lead compound Vpr8. In parallel, using Vpr8 as the scaffold, we will develop a new series of PROTAC drugs that engage the ubiquitin ligase activity of DCAF1-containing E3 complexes.

Through phenotypic and functional studies of immune cells, proteomic mapping of immune responses and genomic studies of variant strains, this project will assess the evolution of natural SARS-CoV-2 infection and COVID-19 vaccine responses in hemato-oncology patients. Integration of immunological profiles and genomic outcomes with clinical characteristics will inform future best patient management, especially for those patients at risk of prolonged infection with long term viral shedding.

Our research aim is to improve outcomes for high-risk myelodysplastic syndrome and associated acute myeloid leukaemia patients who are refractory to azacitidine or its derivative decitabine, the most effective pharmacotherapeutics for these blood cancers. To this end, we will identify and evaluate therapeutic alternatives for this population of patients by leveraging discoveries and using clinical samples collected from an on-going investigator initiated clinical trial.

The most aggressive forms of DLBCL are marked by alterations that result in MYC and BCL2/6 activation. In cases without genetic alterations at these loci, the mechanisms underpinning their overexpression remains largely unknown. Herein, we will examine how a putative driver of DLBCL (hnRNP K) impacts disease progression through its direct regulation of these critical oncogenes and evaluate treatment responses using clinical samples and animal models for this high-risk DLBCL patient population.

Current therapy for MPNs remains suboptimal with ongoing risks for thrombosis. Newer drug such as JAK inhibitor has toxicity and is not curative. New targeted therapy with less side effects is urgently needed in the field. This project focuses on the inhibitors of Plek2, a novel target of MPNs. We have identified lead compounds of Plek2 through screening and medicinal chemistry. We propose to further study the mechanisms of action of the inhibitors and perform in vivo studies using MPN models.

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.

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.

We will test rational drug combinations in accurate preclinical model systems that reflect the distinct genomic features of pediatric AML. The use of genetically accurate mouse models to inform clinical translation is particularly important in pediatric AML given its relatively low incidence and difficulties inherent in testing drug combinations in children. Our preliminary studies have identified combined BET and MEK inhibition as a particularly promising combination for pediatric AML.

This project is focused to develop small molecule degraders of ASH1L histone methyltransferase as a treatment for aggressive sub-types of AML and ALL with high expression of HOXA genes by utilizing the PROTAC (proteolysis targeting chimera) approach. Optimization of ASH1L degraders and their comprehensive evaluation in in vitro and in vivo leukemia models are proposed. We expect these studies will lead to new therapeutics for aggressive acute leukemias with high HOXA expression.

This project will evaluate a novel two-drug combination to improve killing of multiple myeloma (MM) cells. First, we will test the hypothesis that statins increase killing of MM cells by BH3 mimetics including venetoclax and the MCL-1 inhibitor AMG 176. Second, we will identify biomarkers that predict response. This project will have significant positive impact on two fields: repurposing statins for blood cancer, and application of BH3 mimetics to improve health and survival of MM patients.

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.
