T cell Memory in Cure of Diffuse Large B Cell Lymphoma: An Investigation of the Immune Interactome

While many patients with diffuse large B cell lymphoma (DLBCL) are cured with initial treatment, some patients relapse even after multiple therapies, and their outcomes are poor; we believe that the quality of the patient’s T cell memory plays a critical role in determining how they respond to treatment. To investigate, we will analyze the response pattern of circulating immune cells in cured and relapsed DLBCL patients, as well as the immune signals generated by the tumors, and create CAR T cells from the T cells with anti-tumor properties found in cured patients. We will evaluate the ability of these CAR T cells to fight lymphoma; if successful, our research can rapidly be translated into new immune therapies for patients with high risk or relapsed DLBCL.

Targeting the microenvironment to increase immunity and immunotherapy response in DLBCL

To survive and proliferate lymphoma cells must co-opt normal cells residing the tumor microenvironment. This process results in the suppression of the activity of immune cells that otherwise will attack cancer cells. In this project we will develop a novel oral treatment that by acting on the microenvironment will restore lymphoma immunity and increase the activity of immunotherapy.

Towards Risk-Adapted Therapeutic Strategies in CNS Lymphoma

This project will significantly advance the treatment and prevention of CNS lymphomas in two key areas. One, we will further develop and validate candidate genomic biomarkers that identify high risk disease and that are useful in risk stratification in future clinical investigations in primary CNS lymphoma. Two, we will evaluate novel pharmacologic interventions that we hypothesize will: a) potentiate both the anti-lymphoma immune response, including agonists of the toll like receptor 7 and 8 pathway, as well as the combination of the anti-CD19 monoclonal antibody tafasitamab plus lenalidomide; and b) antagonize the NFkB pathway, via the orally-administered BTK degrader, Nx-5948, that we have demonstrated to be active in preclinical models using patient-derived CNS lymphomas.

Exploiting escape from Y-inactivation as a synthetic dependency in MYC-driven lymphoma

As a lymphoma develops it expresses genes that are normally silenced to convey a survival advantage. When these genes are on the X or Y (sex chromosomes) they may present a gender-specific therapeutic target. We have identified a gene (DDX3X in females or DDX3Y in males) that is reactivated in lymphomas such that the lymphomas cannot survive if this gene is removed. This project will develop new ways to inhibit DDX3X and Y as a novel treatment for poor-risk and aggressive lymphoma.

KT1, a novel NK trispecific antibody for the treatment of AML and MDS

New treatments for AML and MDS are urgently needed. We have developed and performed preliminary testing of a novel, patent-protected, trispecific NK cell engager named KT1 which targets AML blasts and leukemia stem cells (LSCs) expressing CD33 and CD123 for elimination by effector cells that express CD16a/b. We plan to test the ability of KT1 to release cytokines and facilitate killing of CD33- and/or CD123-expressing targets by different types of CD16a/b-positive effector cell populations including resting natural killer (NK) cells, cytokine-induced memory-like (ML) NK cells, gamma/delta T cells, and macrophages both in vitro and in leukemic mice. We anticipate that a future treatment of AML and/or MDS with KT1 combined with a donor leukocyte transfer of allogeneic NK, ML NK, or gamma/delta T cells will have excellent therapeutic efficacy and a far better safety profile than many currently studied immunotherapies being tested in patients with AML or MDS.

Targeting Leukemia Stem Cells with the Novel Antibody Drug Conjugate

To improve the cure rate of patients suffering from acute myeloid leukemia (AML), our study aims to target resistant leukemia stem cells by developing an 'antibody-drug conjugate' (ADC) against CD99, a protein expressed on these cells. Initial tests of two ADC versions have shown promise in combating AML. Our next steps involve refining the anti-CD99 antibody, identifying the optimal drug for conjugation, and testing the ADC on patient-derived leukemia models. Completing these objectives will pave the way for a phase 1 clinical trial, offering a potentially transformative treatment for AML.

Pluripotent Stem Cell-derived CAR-T and CAR-NK Cells for Immunotherapy of Leukemia and Lymphoma

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.

Mitochondrial reprogramming to restore age-driven dysfunction in T cell and boost CAR-T cell therapy

In the Cancer Immunology field, the “aging” variable has not been investigated profoundly yet, even though aging is the first factor associated to cancer. This represents a major limitation on the significance of the experimental results and their translation to the clinic. We believe that with our proposal we can shade light on important biological processes which drive immunotherapy failure. We have shown that T cell function is dependent not only on the differentiation state but also on their biological age. Thus, taking in consideration aging and the age-driven metabolic defects in T cells will help to better understand their biology and develop better strategies to boost immunotherapy.

Improving outcomes of multiple myeloma using TGF-beta resistant BCMA-targeted CAR T cells

Immunotherapy using chimeric antigen receptor (CAR) T cells, or CARTs for short, holds great promise for improving outcomes and survival of patients with relapsed and/or refractory multiple myeloma (RRMM). Next-generation “armored” CARTs that can overcome transforming growth factor beta (TGF-beta) dependent immune suppression in the tumor microenvironment may provide deeper and more durable disease control than the TGF-beta sensitive CART products currently in clinical use.

Targeting the Osteogenic Lineage as a Therapeutic Strategy in Multiple Myeloma

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.

Enhancing the “fitness” of anti-BCMA CAR T cells for improved efficacy in multiple myeloma

Chimeric antigen receptor (CAR) T cell therapy is a form of immune-based therapy where a patient’s own immune cells are genetically engineered to recognize and kill the tumor cells. This therapy has revolutionized the treatment of certain blood cancers and excitingly, two CAR T cell products were recently approved for the treatment of multiple myeloma.

Despite impressive initial clinical data showing responses in 73-98% of patients, most patients still relapse after CAR-T cell therapy within 3 years. Therefore, there is a significant unmet need to further enhance the effectiveness of CAR T cell therapy in this disease. In this project we will investigate whether an approach we have shown to make CAR T cells “fitter” and more effective in solid tumors is also effective in the context of multiple myeloma.

Toward improvement of BCMA/CST6-CAR-T therapy to target both myeloma cells and bone resorption

We have observed that non-glycosylated CST6 proteins suppress osteoclast differentiation and function without causing immunosuppression. We aim to determine whether BCMA-CAR-T cells which are engineered to secret CST6 proteins kill myeloma cells and suppress bone lytic lesions without immune suppressive effects in myeloma. Our ultimate goal is to develop a CAR-T-cell based immune therapy to prevent bone loss and disease progression in myeloma patients.

Exploiting tumor-immune dynamics to inform curative combination therapy for follicular lymphoma

Follicular lymphoma is a common form of blood cancer, affecting 15,000 new patients annually in the United States, but it remains incurable with conventional treatments. Bispecific antibodies represent a new class of therapies that engage the immune system to attack lymphoma cells and have shown promising effectiveness in inducing remissions in patients with this disease, but even they are unlikely to be curative. Researchers from the Dana-Farber Cancer Institute here propose to analyze lymphoma cells from patients undergoing treatment with bispecific antibodies on several complementary clinical trials to determine how these cells evade the immune system and develop resistance. It is believed that such mechanisms of resistance may reveal vulnerabilities within the lymphoma cells that novel treatments can overcome in combination with bispecific antibodies to cure patients with follicular lymphoma.

Targeting HSP70 to Immune Effector Cells to Overcome the Immune Suppressive Myeloma Microenvironment

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.

211Astatine-CD123 Radioimmunotherapy for Cancer (Stem) Cell-Directed Treatment of Acute Leukemia

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.

Development of a novel BCL2L1 armored CAR T-cell and a tumor-immune interactome in 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.

Arming NK Cells to Target B7-H3+ AML Cells

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.

Strategic combinations to overcome therapeutic resistance and relapse in acute myeloid leukemia

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.

Understanding molecular determinants of immune evasion to CAR-T cells at single clone resolution

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.

Targeting GCK as a novel and selective therapeutic strategy against RAS mutated Multiple Myeloma

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.

Developing Novel CAR-T Cell Therapy For Hematologic Malignancies

We observed that patients with many hematologic cancers expressed high levels of DKK1 and generated novel human DKK1-A2 CAR-T cells that can kill cancer cells from HLA-A2+ patients with myeloma, lymphoma, or leukemia. We also found that Th9-polarized T cells have enhanced antitumor effects in vivo. In this proposal, we will determine 1) whether and how Th9-polarized DKK1-A2 CAR-T cells are promising effector T cells for immunotherapy of human patients, and 2) whether Th9-polarized DKK1-A2 CAR-T cells are associated with reduced on- and off-target toxicities. Completing these studies are critical for developing new and effective CAR-T therapy for patients with hematologic malignancies who are still dying from the disease.

Targeting acetyl-CoA synthetase 2 to remodel obesity-evoked inflammatory microenvironment in myeloma

Our proposal aims to develop a novel strategy to improve therapeutic efficacy for patients with multiple myeloma by remodeling obesity-induced inflammatory microenvironment. We hypothesize that acetyl-CoA synthetase 2, which is stimulated by obesity, enhances inflammatory cytokine production from myeloma cells, leading to an inflammatory niche where anti-tumor function of CD8+ T cells is dampened, and tumor growth is promoted. Our study will be the first to explore a novel insight for how obesity impacts the interaction between myeloma cells and microenvironment. In preparation of using the inhibitor of acetyl-CoA synthetase 2 in the clinical setting, we will establish its potential as a single agent or in combination of other chemo- or immuno- drugs to treat myeloma.

Memory-like natural killer cells and venetoclax to eradicate measurable residual disease in AML

This proposal is to conduct a phase I (early phase) clinical trial to test whether the combination of the approved targeted therapy venetoclax with memory-like Natural Killer (NK) cells is safe and active in patients with acute myeloid leukemia (AML). Based on laboratory research at Dana-Farber Cancer Institute, we believe that the addition of memory-like NK cells obtained from an haploidentical (‘half matched’) donor will be able to eradicate residual leukemia cells left over after prior venetoclax treatment and hence prevent a future relapse of the disease. A total of 10 patients will be treated with two different doses of NK cells and a constant dose of venetoclax. We also plan scientific studies on patient samples to learn more about the function of NK cells when combined with venetoclax, evaluate for clearance of residual leukemia cells with this combination therapy and explore potential resistance mechanisms.

Designed biosensor to enhance CAR T cell therapy for multiple myeloma

We will develop a novel T cell therapy strategy for multiple myeloma (MM) that will combine existing chimeric antigen receptors (CARs) with a novel designed biosensor responding to soluble factors abundantly present in the MM bone marrow environment in patients. The biosensor will be expressed as novel type of chimeric receptor in T cells concomitantly with the CAR and signal the T cells to persist longer and keep eliminating cancer cells from the body. We will deeply characterize the effects of our novel biosensor in CAR T cells to precisely understand how the treatment works. If successful, we expect that CAR T cell therapy for MM can be made more efficient, and the same strategy could potentially also be applied to other cancer types.

Pharmacological strategies to enhance T- and NK-cell-based therapies in blood cancers

Although they represent a major therapeutic progress for blood cancers, CAR-T cells and other T-cell based therapies are subject to eventual development of resistance to many patients. Natural killer (NK) cell-based therapies are highly active against many types of blood cancer cells which are resistant to T cells, but in our CRISPR studies death receptor signaling defects emerge as a common downstream mechanism of resistance to both T- and NK-cell therapies. Building on extensive pharmacological and genomic screens, this project will specifically examine the role of SMAC mimetics and JAK/STAT inhibitors in enhancing the response of blood cancer cells (e.g., multiple myeloma, leukemias) to CAR-T or NK cell therapies. We will place emphasis of studies with patient-derived samples in vitro (Integrated Functional Immune Profiling Platform) and in vivo, including humanized bone marrow-like scaffolds, to provide a translationally-relevant simulation of the potential of these compounds to enhance the clinical activity of cell-based immunotherapies in blood cancers.

Targeting mutated MYD88 pro-survival signaling in B-cell malignancies

Our laboratory and those of others discovered highly recurring mutations in the gene MYD88 which are found in patients with various B-cell cancers including Waldenstrom’s Macroglobulinemia (95-97%), ABC Subtype of Diffuse B-cell Lymphoma (30-40%), Primary Central Nervous Lymphoma (80%), Marginal Zone Lymphoma (10%) and Chronic Lymphocytic Leukemia (5-10%). Our laboratory and those of others showed that mutated MYD88 triggers BTK, which is the target of BTK-inhibitors like ibrutinib, acalabrutinib and zanubrutinib though complete remissions are rare with these agents largely in part because other pro-survival molecules are activated by mutated MYD88 such as HCK and IRAK1. In these studies, we will develop potent and selective inhibitors to HCK and IRAK1, including PROTACs which inhibit and degrade these molecules, using lead molecules and scaffolds whose target selectivity and activity we previously validated. We will also investigate the mechanisms underlying the inactivation of the Inhibitor of BTK (IBTK) as a potential new target for development of inhibitors for use in MYD88 mutated lymphomas.

Analysis and Targeting of Tumor-Associated Monocytes/Macrophages that Inhibit PD-1 Blockade

Inhibition of a tumor-triggered immune exhaustion pathway, termed PD-1 blockade, enables immune effector cells to attack cancers. In classic Hodgkin Lymphoma (cHL), PD-1 blockade is now a standard treatment for relapsed disease and a component of experimental frontline therapy. We have identified a major population of monocyte/macrophages in patients with cHL that inhibit tumor cell killing and limit the efficacy of PD-1 blockade. Our goal is to fully characterize these tumor-specific monocytes/macrophages and target their immunosuppressive and tumorigenic program for therapeutic benefit in patients with cHL and other lymphoid malignancies.

Towards clinical testing of epitope editing to enable novel adoptive immunotherapies

Innovations in gene engineering have made it possible to reprogram immune cells to attack specific targets on cancer cells, allowing the first adoptive cellular immunotherapies, known as CAR T cells, to be approved by the FDA for the treatment B lymphoblastic leukemia. A similar approach is currently under development for AML, but in contrast to B-ALL, there is no leukemia-specific target which would be amenable to targeting by immune cells without incurring severe adverse effects. Here, we aim to modify normal bone marrow stem cells used for allogeneic transplantation to make them resistant to CAR-T cells, thus enabling targeting proteins essential for tumor survival without the risk of severe toxicity on the healthy tissue counterpart.

Adenylate Kinase 2-A Novel Therapeutic Target in Multiple Myeloma

We identified the adenine nucleotide regulator AK2 as a selective dependency in multiple myeloma (MM) that is more essential for survival of MM cells overexpressing the histone methyltransferase NSD2. Here, we propose a series of experiments to understand the role of AK2 in MM cell fitness and response to existing therapies and elucidate the molecular basis of the increased dependence on AK2 driven by NSD2 overexpression. This study will elucidate the effects of AK2 inhibition in MM and will credential the enzyme as a therapeutic target.

Targeting aberrant non-canonical NF-κB pathway activation in B-cell lymphomas

The impact of biological heterogeneity on treatment outcomes is evidenced by a large proportion of lymphoma patients who experience relapsed/refractory disease. To address this knowledge gap, we sequenced primary lymphoma samples and found recurrent mutations in the non-canonical NF-kB pathway (NC NF-kB) and uncovered the NIK kinase as a targetable candidate. Our next steps focus on using advanced genetic modelling approaches to provide preclinical rationale for targeting NC NF-kB in lymphomas.

Niclosamide for the Treatment of Relapsed/Refractory Pediatric Acute Myeloid Leukemia

Niclosamide is an FDA approved anti-parasitic drug that is well tolerated and acts synergistically with chemotherapy to kill AML cells. We will conduct a Phase I clinical trial with niclosamide in combination with cytarabine for children with relapsed/refractory pediatric AML. ShRNA/CRISPR screens demonstrated that Bcl-2 is upregulated in niclosamide resistant cells. We will study the effects of the Bcl-2 inhibitor venetoclax in combination with niclosamide in pediatric AML.

TCR directed immunotoxins and antibody drug conjugates for the treatment of T cell malignancies

Few treatment options are available for T cell leukemias and lymphomas, collectively called T cell cancers that affect ~100,000 patients worldwide each year. The current proposal will generate new antibodies attached to drugs and toxins that kill the T cell cancers. Importantly, the antibodies will preserve enough healthy T cells to maintain a functioning immune system. These modified antibodies may improve patient outcome and limit side effects associated with traditional chemotherapies.

Overcoming RAS-driven Mechanisms of Resistance in Leukemia

The mitogen-activated protein kinase (MAPK) pathway is activated in high-risk leukemia and is a hallmark of resistance to therapies. This project uses patient-derived xenograft models of relapsed pediatric ALL and AML with activated RAS/MAPK to test whether clinically relevant MAPK mutations activate the VAV3/RAC pathway and if pharmacological inhibition of that pathway by a small molecule we developed synergizes with a MAPK-inhibitor to provide a new treatment strategy for RAS-driven leukemia.

Targeting SYK:ZAP70 coexpression in refractory B-cell malignancies

The B-cell kinase SYK and its T-cell homolog ZAP70 have almost identical functions but are strictly segregated to B- and T-cells. We recently discovered that B-cell malignancies frequently coexpress ZAP70 and that only SYK but not ZAP70 can trigger negative B-cell selection and cell death. Here we test the hypothesis that ZAP70 enables malignant B-cell transformation, test pharmacological SYK-hyperactivation and validate ZAP70 as biomarker of patients who benefit from this approach.

Acute myeloid leukemia (AML) is a blood cancer characterized by poor clinical outcomes. We developed an antibody that inhibits AML in models by triggering anti-leukemia immunity. Now we developed a new version of this antibody with higher affinity to the leukocyte receptors that mediate anti-leukemia immunity. We will establish the ability of this optimized antibody to elicit greater inhibition of AML. The studies will generate important information about how to induce anti-leukemia immunity.

Therefore, immunotherapy targeting the novel MMP-13/PD-1H interaction module represents a novel approach to cure this devastating cancer.

Development of natural killer (NK) cell-based therapies to treat MYC-high pediatric lymphoid cancers

Refractory pediatric B- and T- lymphoid cancers exhibit hyperactivation of MYC and its downstream pathways. Experimentally, MYC inactivation sustains tumor regression. However, MYC’s requirement in normal B/T-cells has hampered the development of MYC inhibitors. Recently, we showed that MYC-High B/T-Lymphoid Neoplasms (B/T-MLN) evade Natural Killer (NK) cell surveillance. Hence, we propose to develop targeted off-the-shelf NK therapies as an alternative to MYC inhibition for treating B/T-MLN.

Preventing follicular lymphoma progression and transformation through precision therapy

Follicular lymphomas (FL) depend on stromal cells for survival and proliferation and evade T-cell immune surveillance. Although indolent, most FLs eventually undergo either progression or transformation to an aggressive lymphoma. Effective treatments to prevent this remain a critical unmet need. This proposal will develop novel, mechanism-based therapeutic regimens for FL that overcome defective immune surveillance, prevent FLs from receiving stromal support and prevent disease progression.

XPO-1 as a novel therapeutic target in GATA-3 expressing mature T-cell lymphomas

GATA-3 identifies high-risk subtypes of mature T-cell lymphomas (MTCL), as its target genes, which we have systematically identified, have significant cell-autonomous and non-cell-autonomous (by regulating constituents of the tumor microenvironment) roles in these MTCL. As our preliminary data suggests that XPO-1 inhibition is a novel, and largely unexplored, therapeutic strategy in these MTCL, we will examine its cell-autonomous (Aim #1) and non-cell-autonomous (Aim #2) role in GATA-3+ MTCL.

Restoring lymphoma immunosurveillance by combined EZH2 inhibition and immunotherapy

The project builds on evidence that mutations leading to persistent EZH2 activation drive germinal center B-cell lymphomagenesis by disrupting T-cell surveillance, and will test the hypothesis that EZH2 inhibition synergizes with immune checkpoint blockade and/or co-stimulation to eradicate these diseases. These results will provide the rationale for clinical development of precision-medicine immune-epigenetic combination therapies for lymphomas where these mechanisms are specifically altered.

Testing targeted therapy in LCH

We propose to the hypothesis that patients with LCH who fail initial chemotherapy will respond to a targeted strategy of blocking MAPK signaling through MEK inhibition.  This trial is a Phase 2 study to evaluate the safety and efficacy of cobimetinib in patients with refractory LCH.  Exploratory aims will evaluate response of lesions with specific mutations, ability of peripheral blood mononuclear cells to determine disease burden, and development of somatic mutations in patients who relapse.

Development of LILRB1-based immunotherapy for multiple myeloma treatment

LILRB1 is a human immune inhibitory receptor expressed on a variety of immune cells. Based on preliminary data, we hypothesize that blocking LILRB1 signaling in immune effector cells of myeloma patients will lead to increased anti-cancer activities of immune cells. We will identify subsets of myeloma patients with higher LILRB1 expression on immune cells, and determine whether anti-LILRB1 antagonizing antibodies can improve the function of immune cells for multiple myeloma treatment.
