Research we fund

AML risk stratification established by previous studies do not reflect survival outcomes observed in Black patients. Exome sequencing of 100 Black AML patients revealed the novel variants previously not affiliated with AML, including PHIP. Using multiomic patient sample captures and GEMMs, we will functionalize variants in PHIP and assess if they drive leukemogenesis and/or therapy resistance. The overall goal of this work is to implement inclusive genetic assessment tools for AML diagnosis.

Myelodysplastic neoplasms are malignant disorders driven by expansion of diseased hematopoietic stem cells and progression to leukemia. Our investigations have identified the important role of the transporter of amino acid glutamine SLC38A1 in sustaining metabolic demands of rapidly growing malignant stem cells. The goal of this project is to genetically target this transporter to understand its role on tumorigenesis and progression; and to develop SLC38A1 inhibitors as novel therapeutic tools.

We have observed that non-glycosylated CST6 proteins suppress osteoclast differentiation and function without causing immunosuppression. We aim to determine whether BCMA-CAR-T cells which are engineered to secret CST6 proteins kill myeloma cells and suppress bone lytic lesions without immune suppressive effects in myeloma. Our ultimate goal is to develop a CAR-T-cell based immune therapy to prevent bone loss and disease progression in myeloma patients.

TP53-Y220C is a recurrent hotspot TP53 mutation observed predominantly in AML and MDS among hematological malignancies. This study aims to investigate the mechanism of action and therapeutic activity of PC14586, a compound designed to bind p53-Y220C protein and stabilize it in the wild-type conformation and to develop mechanism-based combinations that improve its efficacy in TP53-Y220C mutant AML.

Follicular lymphoma is a common form of blood cancer, affecting 15,000 new patients annually in the United States, but it remains incurable with conventional treatments. Bispecific antibodies represent a new class of therapies that engage the immune system to attack lymphoma cells and have shown promising effectiveness in inducing remissions in patients with this disease, but even they are unlikely to be curative. Researchers from the Dana-Farber Cancer Institute here propose to analyze lymphoma cells from patients undergoing treatment with bispecific antibodies on several complementary clinical trials to determine how these cells evade the immune system and develop resistance. It is believed that such mechanisms of resistance may reveal vulnerabilities within the lymphoma cells that novel treatments can overcome in combination with bispecific antibodies to cure patients with follicular lymphoma.

Despite remarkable progress in the last 20 years, multiple myeloma remains an incurable disease. In recent years, 2 CAR T cell products that target BCMA on the myeloma cell have been approved. These products result in remarkable initial responses however the duration of these responses has been disappointing. In this proposal, we will take a novel approach to isolate and characterize myeloma cells that interact with CAR T cells but are not killed by them as a potential resistance mechanism.

Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma characterized by resistance to standard treatments and short survival. For the 2023 LLS MCLII Synergistic Team Award, we have assembled a team of leaders in basic, translational, and clinical research in MCL to tackle the current significant obstacles in understanding and treating MCL. In the last decade, we investigated the therapy resistance mechanism of MCL, and pioneered clinical trials for targeted therapies (ibrutinib, lenalidomide) and chimeric antigen receptor T-cell (CAR-T) therapy. However, despite these dramatic advancements, resistance to these newer therapies, including targeted therapy and CAR-T cells, is seen in over 50% of patients. Thus, it remains an unmet need to better define the mechanisms of resistance and then develop rationally designed strategies to overcome resistance. The overall goal of this Synergistic Team Award is to develop improved curative therapies for patients with MCL at relapse. The goals will be addressed in three highly focused, independent but highly integrated projects that utilize state-of-the-art genomic technologies, patient-derived xenograft models, clinical data and primary MCL samples. With the joint effort of our laboratories, highly interactive and accomplished scientists, and physician researchers from multiple institutions with expertise in MCL and therapy, we are uniquely poised to develop improved next-generation of combination therapy for relapsed MCL patients.

The focus of my research is to evaluate the efficacy of and to unravel the molecular mechanisms underpinning a novel drug combination in AML targeting oncogenic protein translation and apoptosis. We will utilize genetic perturbation and other orthogonal approaches, including in vitro and ex vivo assays, and in vivo AML PDX models. The goal of my research is to transform the clinical management of AML patients, particularly for relapsed and difficult-to-treat subgroups.

In July 2012, LLS began its partnership with Constellation to support three first-in-human Phase 1 clinical trials for blood cancer patients and the partnership led to the ongoing trial "A Phase 3, Randomized, Double-blind, Active-Control Study of CPI-0610 and Ruxolitinib vs. Placebo and Ruxolitinib in JAKi Treatment Naive MF Patients."

Constellation Pharmaceuticals was a clinical-stage biopharmaceutical company developing novel therapeutics that selectively modulate gene expression to address serious unmet medical needs in patients with cancer. MorphoSys acquired Constellation in July 2021 and continues to enroll patients with myeloproliferative neoplasms in multiple clinical studies.

Pelabresib (CPI-0610) is a small molecule inhibitor of bromodomain and extra-terminal (BET) proteins. A Phase 3 clinical trial (NCT04603495) of pelabresib in combination with ruxolitinib for myelofibrosis patients that have not been previously treated with Janus kinase inhibitors completed enrollment.

NPM1-mutated leukemia is the most common AML in adult and characterized by upregulations of HOXA/B genes and MEIS1. Given the importance of oncogenic transcriptional program, I will determine regulatory molecules that cooperate with mutant NPM1 on chromatin by combining CRISPR/Cas9 screening approach in an innovative model system of endogenous transcription reporters with proteomics approach. This will facilitate identification of novel therapeutic targets specific for NPM1-mutated AML.
