Research we fund

Outcomes for acute myeloid leukemia (AML) and multiple myeloma (MM) patients remain inadequate and new treatment options to combat resistance against existing agents are urgently needed. My research aims to identify and target selective vulnerabilities of AML and MM cells. I am particularly interested in epigenetic and metabolic pathways that control self-renewal and differentiation of hematopoietic cells and that can be leveraged to modulate cell fate for therapeutic benefit.

The primary focus of research is to better understand mechanisms of resistance to immunotherapies and design treatment approaches to improve outcomes. I hope to accomplish this by conducting clinical trials that concurrently target both BCMA and GPRC5D in patients with advanced multiple myeloma and by studying antigen expression, tumor genetics, and T cell characteristics to better understand mechanisms of resistance. The goal is to develop more effective immune treatments for myeloma.

Mutations in RNA splicing factors, particularly those involving the core splicing factor SF3B1 are amongst the most common mutations found in myeloid neoplasms. We recently identified a cofactor protein known as GPATCH8 which is required for the aberrant function of mutant SF3B1. We now seek to understand and target the ways in which GPATCH8 and SF3B1 interact. In so doing we hope to develop new treatments for leukemias containing mutant splicing factors.

We are evaluating two parallel clinical trials with synergistic immunotherapies in mantle cell lymphoma (MCL), including 1) tafasitamab and lenalidomide and 2) glofitamab and lenalidomide. We will investigate how these treatments impact the MCL immune microenvironment and mediate anti-tumor immune responses, and will correlate these changes with outcome.

Our goal is to develop safe, effective, and "off-the-shelf" immunotherapies to improve outcomes for patients with relapsed, refractory MCL.

Advances in the treatment of Langerhans cell histiocytosis and Erdheim-Chester disease have led to a growing survivor population; however, there is a lack of information regarding the long-term outcomes, healthcare needs, and health-related quality of life in the era of targeted therapies. We propose the creation of a large national cohort of survivors with histiocytosis to address unanswered questions, eventually leading to targeted survivorship programs for this vulnerable population.

Vitamin A is safe, well tolerated and positively affects gut immune health. Graft versus host disease (GVHD) is a life-threatening complication of bone marrow transplant (BMT) which happens due to inflammatory changes in the gut. We harnessed the anti-inflammatory properties of vitamin A by giving it to children before bone marrow transplant (BMT) and showed reduction in acute gut and moderate/severe chronic GVHD. We will validate our findings in this currently proposed study of an independent group of adult BMT patients. We will give vitamin A or placebo before BMT to adult BMT patients and observe for reduction of chronic GVHD in vitamin A recipients compared to placebo. This study will be a step forward in adoption of vitamin A as a universal strategy to prevent GVHD which is affordable ($1.25 for entire treatment), non-toxic, and doesn’t suppress the immune system.

Our focus is to unravel how clonal hematopoiesis (CH) progresses to leukemia. We will investigate how epigenetic heterogeneity affects Tet2-mutant hematopoietic stem cells (HSCs) during aging. We plan to simultaneously trace HSC clonal identity and clonal history by genetic barcode and single-cell multi-omics and determine their epigenetic configurations adaptive in the aged, inflammatory bone marrow. The long-term goal is to create innovative therapeutics to mitigate CH and prolong health span.

In collaboration with 10 community-based oncology practice sites, this study will implement a multi-level intervention trial to test the effectiveness of two community oncology strategies designed to increase trial accrual by focusing on a) enhancing the relationship between community oncologists and trial PIs and reducing barriers to referral, and b) an interactive online training focusing on improving community oncologists’ knowledge and attitudes about trials, as well as their ability to discuss clinical trials with their patients. ​

Fertility preservation (FP) treatments can prevent infertility caused by blood cancer. However, FP costs are high, and these services are typically not covered by insurance, contributing to low utilization. New state laws require insurers to cover FP, but it is unknown if they improve access to care. Using national insurance data, this study will examine how much out-of-pocket costs remain, whether patients’ share of costs is like that of other cancer services, and whether and which types of laws increase use and affordability.

Black and Hispanic individuals diagnosed with Hodgkin lymphoma (HL) face worse survival rates across all ages. Using an innovative data source, this study will examine differences by insurance status in the receipt and quality of HL treatment in Aim 1 and care engagement and support after treatment (survivorship care) in Aim 2. Using diverse patient voices, this study will characterize and understand how patients make decisions about treatment and survivorship care by insurance type in Aim 3.

Cytotoxic cells of the immune system, including T and NK cells, can be targeted to seek out and destroy leukemia, lymphoma and myeloma cells by engineering them to express chimeric antigen receptors (CARs) which empower the cell to home to and kill the cancer cells. Typically, such CAR-T and CAR-NK cells are generated from a patient's own blood, but sometimes heavy pre-treatment with chemotherapy leaves inadequate supplies of T and NK cells. We propose to generate T and NK cells from Pluripotent Stem Cells, which through genetic manipulation can be rendered suitable for treating any patient with an "off-the-shelf" cell product, hence facilitating otherwise cumbersome, labor-intensive, and expensive patient-specific cell therapies.

Relapse in patients with acute myeloid leukemia (AML) after hematopoietic cell transplant (HCT) is associated with extremely poor prognosis and thus remains a major unmet need. Natural killer (NK) cells are attractive for treating relapse in the post-HCT setting as these cells are not associated with causing graft-versus-host-disease. Cytokine-induced memory-like (CIML or memory-like) NK cells described by our group, demonstrate enhanced anti-leukemia activity, and persist for up to several months in an immune compatible post HCT setting (when derived from the stem cell donor). The goal of this trial is to evaluate donor CIML NK cells early after HCT in AML patients with measurable residual disease (MRD) and therefore otherwise with a high risk of relapse.
