Research we fund

The field of cancer treatment has made remarkable progress with the adoption of targeted therapy; however, small molecule drugs have limitations such as drug resistance and off-target toxicities. To overcome these challenges, we have developed an innovative approach that enhances the potency and precision of small molecule drugs. Our cutting-edge high-precision pretargeted nanoparticles can deliver potent triple inhibitors that effectively combat drug-resistant mantle cell lymphoma and dual proteolysis targeting chimeras (PROTACs) for treatment of transformed follicular lymphoma. Our proposal is supported by extensive preliminary data, and we are excited to be at the forefront of this revolutionary novel treatment strategy.

Development of a strong anti-cancer immune response requires coordinated action of the innate and adaptive parts of the immune system, but cancer cells alter their environment to suppress virtually every step in this process, which promotes cancer progression and treatment resistance. One promising strategy could be to target Heat shock protein 70 (HSP70), which plays an important role in both innate and adaptive immunity, and we therefore developed a series of novel antibodies to HSP70, one of which cured mice of multiple myeloma. Based on strong preliminary data, we propose additional studies to better understand how this antibody activates various types of immune cells, how it works against both cancer cells and modifies the immune environment in mouse models, and how it could work even better in combination with other agents against myeloma. Since this antibody is already being developed into a drug for phase I clinical trials, these studies will directly inform its use in the clinic against multiple myeloma, and possibly against other blood-related cancers such as B-cell lymphomas.

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.

We have investigated the consequences of p53 loss on stem cell properties, namely clonogenic growth, self-renewal, and drug resistance in multiple myeloma. We have found that both the level of Notch signaling and BCMA impact these properties, and we will explore novel strategies to improve outcomes in p53 mutant multiple myeloma.

Novel immune approaches have revolutionized the treatment paradigms in multiple myeloma (MM) with deep responses seen in heavily pretreated patients. However responses are largely not durable with significant gaps remaining in our understanding of the mechanisms mediating the immune escape to to CAR T cells and T cell engagers. Harnessing the power of single cell immunogenomics and building on the knowledge we amassed to date, we plan to address these therapeutics and mechanistic challenges firstly through the informed design and clinical development of a BCL2L1 armoured BCMA-targeting CAR T cell, and secondly by establishing a dictionary of the MM-TME interactome through serial interrogation of primary MM cells and their immunome generating a dynamic risk prediction model to better guide the delivery of immuno-therapeutics.

In order to develop a novel immunotherapy approach to treating AML, we propose targeting B7-H3 (CD276), a promising immune checkpoint that has been reported to inhibit NK cell activation. We have generated a novel anti–B7-H3 monoclonal antibody (T-1A5) to block B7-H3 function, showing the best in vitro and in vivo activity against AML cells. We will test the hypothesis that combination strategies such as targeting B7-H3 along with BCL2 inhibition (venetoclax) or IL-15r agonist (NKTR-255) result in synergistic inhibition of AML growth.

Acute myeloid leukemia (AML) is the most fatal type of leukemia and has a high rate of relapse following current therapies. We have recently uncovered that RSPO3-LGR4 pathway is a key regulator of leukemia-initiating cell activity and is exclusively activated in relapsed and refractory AML. Our project aims to investigate the mechanistic link between the pathway activation and therapy resistance, and design combination therapies that would overcome resistance and improve the treatment of relapsed leukemia.

Cellular immunotherapies such CAR-T cells are now firmly established as major pillars of anti-cancer therapy particularly in B-cell malignancies. However, despite their remarkable success in mediating an objective clinical response in up to 90% of patients, long-term durable remissions remain confined to only a minority of patients. It is now increasingly apparent that genetic evolution through the acquisition of new mutations cannot solely explain the molecular basis for therapeutic resistance. Therefore, to meet our ambition of precision medicine we need a better understanding of both the genetic and non-genetic mechanisms of malignant clonal dominance and therapeutic adaptation. To address this important challenge, we have developed new ex vivo and in vivo (mouse models) of resistance to CAR-T therapy. These will be coupled to a synthetic clone tracing strategy termed SPLINTR (Single-cell Profiling and LINeage Tracing) using expressed barcodes. In this proposal we will use SPLINTR in our models to uncover the clone intrinsic properties of cancer cells that enable them to evade these pioneering cellular immunotherapies. This research will deliver a blueprint around which future clinical trial strategies could be enabled to improve outcomes with these ground-breaking therapies.

RAS/MAPK mutations are the key drivers in MM, which occurs in 50% of newly diagnosed and higher in relapsed MM patients. However, RAS remains undruggable in MM. We found that RAS mutation MM growth is highly dependent on germinal center kinase(GCK). The goal of this project is to develop small molecule inhibitors against GCK with the expected outcome to provide novel treatments for relapsed/refractory and especially multi-drug resistant MM with RAS mutation, as well as other B-cell malignancies.

Patients with CLL that have progressed on BTK inhibitors have high risk disease with few clinical options. Here we propose a novel, selective inhibitor of PKCβ, MS-553, as a strategy for these patients. Our project will evaluate this drug alone and in combination with venetoclax preclinically and will perform correlative studies from an ongoing phase 1/2 trial of this drug alone and in combination with venetoclax.

Project Term: July 1, 2023 - June 30, 2026

In this project, we will test an innovative therapy called CAR T-cell therapy for children with a type of cancer called AML. In the laboratory, we have identified and developed a powerful CAR T-cell therapy that targets a protein called CD70 on AML cells. We propose to now develop a clinical trial in which we will study the effects of this CD70.CAR T-cell therapy in children with AML.

Double-hit lymphoma (DHL) is an aggressive form of diffuse large B-cell lymphoma (DLBCL) defined by co-occuring MYC and BCL2 rearrangements. DHL has been linked to very poor outcomes when treated with R-CHOP chemotherapy. Effective treatments to prevent treatment failure remain a critical unmet need. This proposal will develop novel, mechanism-based therapeutic regimens for DHL that overcome chemotherapy resistance and defective immune surveillance to improve outcomes.
