Research we fund

Blood cancers called myeloproliferative neoplasms occur when one of the blood stem cells picks up a mutation. Some patients stay in the chronic phase of the disease for years whereas others rapidly progress with poor outcome. We recently measured when the cancer mutation first occurs and the rate of expansion of the cancer cells in individual patients. We will develop a method that uses the history of disease in each patient to identify those that are at risk of progression.

We recently identified a pervasive, pathogenically relevant mutational mechanism that targets super-enhancers (SE) in DLBCL, leading to target gene deregulation. Here we will dissect the mechanistic role of 3 highly recurrent hotspots in the BCL6, BTG2 and CXCR4 SEs in driving lymphomagenesis and tumor dependency in vitro and in vivo using novel mouse models. These studies will significantly transform our understanding of DLBCL and identify novel therapeutic targets.

Based on our preliminary data, we hypothesize that IRAK4 inhibition leads to LSPC reprogramming in MDS and AML. Aim 1 will evaluate the mechanism by which IRAK4 inhibition leads to LSPC reprogramming in cell lines, mice, and PDX samples. Aim 2 will concentrate on understanding of how IRAK4 inhibition creates synthetic lethal dependencies with the CELMoD CC-885 and how neosubstrates of CC-885 mediate the synergy upon IRAK4 inhibition in leukemic cells.

Our research focuses on the preclinical evaluation of new targeted therapies for high-risk subtypes of childhood AML. We are deploying screening approaches to delete each gene, one-by-one, to identify genes whose deletion leads to death of the leukemia cells. We will evaluate drugs developed against these targets in state-of-the-art models of pediatric AML. Our goal is to translate the most promising findings to clinical trials for children with these very poor outcome subsets of AML.

Our recent studies have identified specific bacteria that can potentially promote the growth of human myeloma tumor cells. We are now testing if eradicating these bacteria in MGUS patients will be effective for prevention of myeloma.

Survival rates for those afflicted with MDS have not improved despite extensive effort to identify the key genetic events in its pathogenesis. This project elucidates the contributions of aberrant NPM1 to hematological disorders, with a focus on mitochondrial fitness and inflammasome activation. The resulting insights into the metabolic, genetic and proteomic requirements of homeostasis that are critical to preventing aging will have a major impact on the treatment of hematological malignancies.

The goal of this SCOR project is to identify and eradicate the root cause of acute myeloid leukemia, the so-called leukemia stem cell (LSC). In the previous cycle of this SCOR grant, we developed two unique strategies, each of which efficiently eradicates LSCs in the laboratory. Going forward, we will expand our scientific efforts to further improve these approaches and also conduct clinical trials to determine whether our approaches to killing LSCs will benefit AML patients.

In June 2022, LLS made an equity investment in ImCheck Therapeutics to "Support Clinical Development of the ICT01 Program for Blood Cancer Indications."

ImCheck Therapeutics is designing and developing a new generation of immunotherapeutic antibodies targeting butyrophilins, a novel super-family of immunomodulators.

ICT01 is a humanized, anti-BTN3A (also known as CD277) monoclonal antibody that selectively activates γ9δ2 T cells, which are part of the innate immune system that is responsible for immunosurveillance of malignancy and infections. The EVICTION study is currently enrolling a Phase 2 cohort expansion of ICT01 in combination with azacitidine and venetoclax in patients with newly diagnosed acute myeloid leukemia (NCT04243499).

In January 2023, LLS made an equity investment in BioInvent to "Support Clinical Development of BI-1206 for NHL Indications and BI-1808 for T-Cell Lymphoma Indications Including CTCL."

BioInvent International AB is a clinical-stage biotech company that discovers and develops novel and first-in-class immuno-modulatory antibodies for cancer therapy, with currently four drug candidates in five ongoing clinical programs in Phase 1/2 trials for the treatment of hematological cancer and solid tumors, respectively. The Company's validated, proprietary F.I.R.S.T™ technology platform identifies both targets and the antibodies that bind to them, generating many promising new drug candidates to fuel the Company's own clinical development pipeline and providing licensing and partnering opportunities.

BI-1808 is an anti-TNFR2 antibody being evaluated in a Phase 2 trial, as a single agent and in combination with the anti-PD-1 therapy Keytruda^® (pembrolizumab) in patients with ovarian cancer, non-small cell lung cancer and cutaneous T-cell lymphoma (NCT04752826).

Overactivation of the inflammasome is seen in CMML and leads to worsening of this condition. We will explore the potential of a new inflammasome inhibitor drug, HT-6184, in CMML patient samples and in animal models. Our preliminary results show that this drug can decrease inflammation and improve red cell development in CMML models. The new drug is approved for clinical trial use and our work will potentially lead to its use in clinical investigations in CMML.

Chronic myelomonocytic leukemia (CMML) is a rare but poorly understood blood cancer often presenting with crippling inflammatory symptoms that frequently evolves into acute leukemia. In an ongoing clinical trial, we have compelling molecular and clinical data that this disease responds effectively to blockade of GM-CSF with lenzulimab, a well-tolerated and safe antibody, in combination with azacitidine. Here, we propose an integrated research program to investigate targeting of the GM-CSF pathway in high risk CMML using our carefully matched patient samples, proprietary GM-CSF tools, and humanized in vivo CMML models.

Multiple myeloma causes devastating bone disease characterised by focal bone lesions and generalise bone loss, which leads to an increase in bone fractures. Current therapies only stop bones from getting worse so patients continue to suffer fractures. We discovered that inhibiting a molecule called sclerostin in mice increases bone and is much better than current treatments. In this program we will investigate whether inhibiting sclerostin is able to restore lost bone and reduce fractures in patients with myeloma.
