Research we fund

The goal of our work is to use a “bench to bedside and back” approach to develop new treatments for patients with relapsed/refractory AML. Through genetic analysis of patients who relapse or do not respond to standard and investigational treatments, we discover potential resistance mechanisms. In the lab, we test novel drugs and identify new drug targets that may address these resistance mechanisms when used in combination with other therapies. The overall goal of our research program is to improve treatment options and survival of patients with refractory AML.

We focus on blastic plasmacytoid dendritic cell neoplasm (BPDCN), an aggressive blood cancer with limited treatment options and poor outcomes. We want to understand what causes the disease, develop laboratory tools, and identify new treatments and ways to overcome therapy resistance. We have translated our discoveries to clinical trials. Our goal is to continue this bench to beside approach to develop the next generation of BPDCN therapies that improve survival and minimize treatment toxicity.

We are investigating new interventions that could improve the effectiveness of CAR T-cell therapy for lymphoma. A clinical trial will test radiation immediately followed by CAR-T. Larger lymphoma tumors are less likely to respond to CAR-T and we expect that radiation could reduce the amount of tumor, leading to improvement in responses. We will also conduct a series of trials to determine the effectiveness of vaccinations before and after CAR T cell therapy, and if anti-cancer vaccines could improve outcomes.

We want to understand how leukemia inhibits blood production as this is one of the main causes of death in leukemia patients. We use new microscopy techniques developed by our group to image—for the first time—all types of blood cells and how they are eradicated by leukemia cells. Identification of the mechanisms through which leukemia inhibits blood production will be the foundation for new studies to develop drugs to maintain normal blood levels and prevent death in leukemia patients.

CAR T-cells are highly effective in lymphoma but limited by a profound and potentially fatal toxicity involving the central nervous system (CNS). Little is known about how CAR T-cells eliminate lymphoma cells in the CNS nor how this therapy causes toxicity. I will study CAR T-cells in patients with CNS lymphomas with the goal of expanding CAR T-cell indications. I will also examine serial blood and CNS samples to understand neurologic toxicity to inform new therapies to control this toxicity.

Coming soon.

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.

In this proposal, the Choi lab is investigating mechanisms that underlie aggressive forms of T cell lymphoma. They have found a gene mutation that is found exclusively in aggressive subtypes. There is a gene that encodes for PD1 that suppresses tumor progression. In a subset of T cell lymphomas, this gene is lost or inactivated, leading to increased tumor progression and aggressiveness. Here they propose three complementary approaches to understand how this gene constrains T cell lymphomas and importantly, they are now proposing to leverage this information to generate novel treatments for the patients who need it most.
