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.

Leukemia recurrence remains the most common type of treatment failure after allogeneic hematopoietic cell transplant for children and young adults with high-risk acute myelogenous leukemia (AML), occurring in 40-50% of patients. Novel treatment strategies are needed to attain durable remissions and provide long-term cure. We have developed a novel memory-like (ML) NK cell immunotherapy that has demonstrated potent activity against AML in preclinical and early clinical studies. We propose a new clinical trial combining donor-derived ML NK cells adoptive cellular therapy with modified αβT cell-depleted haploidentical HCT to enhance graft-versus-leukemia and reduce relapse in pediatric and young adult patients with high-risk AML.

T-acute lymphoblastic leukemia (T-ALL) is an aggressive leukemia with limited treatment options after first-line chemotherapy. Our preclinical work in animal models of T-ALL demonstrated the activity of a novel-novel combination treatment strategy, which includes LP-118 (activator of suicide pathways within leukemic cells) and tyrosine kinase inhibitors (inhibiting growth-promoting LCK and ACK1 signaling pathways). Leveraging the mechanistic insights gained from our laboratory work, we propose a phase Ib/II study investigating the feasibility and efficacy of the combined LP-118, ponatinib, and salvage chemotherapy in patients with relapsed T-ALL. This precision medicine approach addresses an unmet need in a fatal disease which lacks effective therapies.

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.
