Pancreatic cancer is the 4th most common cause of cancer death in the United States with one of the worst survival rates of any cancer. Patients with pancreatic cancer struggle to find clinical trials given the lack of options, the lack of any promising findings, the lack of functionality to tolerate many trials. Our research directly impacts cancer patients providing an innovative and promising therapy that has had success in other cancers. Our clinical trial will study pancreatic cancer patients receiving treatment with their own immune cells that we will have taken from their blood, re-engineered the cells to fight their cancer, and injected their re-engineered immune cells back into their body.Our research will study the blood from these patients and look for markers that are associated with treatment response in similar clinical trials. We will also study their tumor tissue before and after treatment and look to see if the injected, re-engineered immune cells were able to travel to the tumor, grow and thrives and kill cancer cells.

There is a new kind of cancer treatment called immune checkpoint blockade (ICB) that helps the body fight cancer by making the immune system stronger. Doctors use ICB with chemotherapy to treat triple-negative breast cancer (TNBC), but it doesn’t always work for everyone, so we need to find better ways to help these patients.
Scientists are studying tiny living things called microorganisms, like bacteria, that live in and on our bodies. These microorganisms can help us stay healthy and fight diseases. New research suggests that the gut microbiome—the collection of microorganisms in the digestive tract—might influence how well these treatments work. Some types of bacteria can help people respond better to the ICB treatment because they release beneficial metabolites.
In this project, scientists want to see if probiotics (which are good bacteria) or the beneficial metabolites they make can make the cancer treatment work better. They will look at samples from patients before and after treatment to see if these good bacteria and metabolites are helping.

Despite its exciting impact, most cancer patients still do not benefit from immunotherapy. We have discovered a strategy used by cancers to avoid detection by the immune system. This work aims to use markers to determine which patients would be more likely to benefit from blocking this pathway in order to improve the effectiveness of immunotherapy. Using such a tailored approach is expected to enhance responses in a greater number of patients while avoiding the use and costs of ineffective therapies.

About half of all cancer patients will get radiation therapy (RT) as part of their treatment. But some cancers are naturally resistant to RT, and others become resistant over time. One idea to fight this resistance is to combine RT with treatments that boost the body’s immune response. In this project, we will test if a particular type of immunotherapy can overcome resistance to radiation and make RT work better. To check this idea, we’ll start by using lab mice to figure out the best way to do this treatment. These mouse tests will show us when to give the immunotherapy with RT for the best results. Once we know this, we’ll start a clinical trial with pet dogs that have cancer. The goals of this trial are to (1) prove that combining localized immunotherapy with standard RT is safe, and (2) show that this mix works better than just RT alone. The specific immunotherapy we’re looking at is called XCSgel-IL12. It’s a new type of treatment we made. It gets injected straight into the tumor, and it can be made in large amounts for a low cost. It looks very promising for beating radioresistance in many cancer types. This study will focus on soft tissue sarcoma. If it works well, we can start trials in humans with this type of cancer. It could also spark more research on combining RT with XCSgel-IL12 in other cancers in the future.

Pediatric Diffuse Midline Gliomas (DMGs) and High-grade gliomas (HGGs) are aggressive brain tumors. Unfortunately, current treatments don’t work well for these tumors. Our research shows that energy pathways play a role in making these tumors resistant to treatment. Specifically, proteins involved in energy use become more active in resistant tumors. Our recent findings suggest that disrupting these pathways could be a new way to fight these tumors.
In our upcoming study, we will test a compound that acts like glucose but interferes with energy use. We will also test other ways to target the weaknesses of these tumors. Our tests will measure protein and gene activity, energy use, and how combination treatments work.

Cancer immunotherapy has been one of the great advances in the treatment of cancer in the past decade. In B-cell cancers, hijacking T-cells by insbertion of a synthetic receptor (CAR-T cells) enables these cells to recognize and kill lymphoma through a specific marker (CD19). However, despite CAR-T leading to high rates of remission, only about 40% of patients are cured. Some major causes for why CAR-T does not work in patients is too great a burden of tumor cells and the cancer learning to hide the target the CAR-T needs to be effective. Therefore, there is great interest in combining CAR-T with other cancer therapies to improve efficacy. We have a clinical trial combining 2 drugs, mosunetuzumab and polatuzumab, targeting other lymphoma markers (CD20 and CD79b), together with CAR-T in patients with aggressive B-cell lymphomas. Using this approach, we hope to improve outcomes by addressing the main reasons for CAR-T failure. In this grant, we will track a patient’s response to treatment by monitoring a patient’s blood for small tumor fragments, to allow us to determine when extra therapy is needed in addition to CAR-T. We will precisely measure the amount of target markers on lymphoma cells to assess its importance for success of this therapy. Lastly, as CAR-T therapy has a high risk of infection, we will monitor recovery of the immune system to learn how adding extra therapies may affect a patient’s risk.

Pancreatic cancer is a really bad disease that’s hard to treat. Even though treatments like immunotherapy have helped with other cancers, they haven’t worked well for pancreatic cancer. Some people get pancreatic cancer because of a problem gene passed down in their family, like BRCA. We tried treating these people with a mix of immunotherapy drugs, and it worked amazingly well for a few. Their cancer completely went away, and they stayed cancer-free for over 5 years. Now, we’re trying to figure out why it worked for some and not others. We are doing some lab experiments in mice with pancreatic cancer and it seems like something in the cancer cells called STING might be the main reason why this treatment is working. We want to study more tumors from people with pancreatic cancer and the BRCA gene problem to confirm this. Also, we plan to do more tests on mice to see if we can make STING work better in those that don’t respond to treatment at first. If these tests work, it could help create a new treatment for pancreatic cancer in the future.

Blood cell cancers often bear mutations in STAT3. This protein is normally beneficial but, when overactive, becomes a cancer ‘driver’. More than 150 relevant mutations have been identified but only 7 have been studied in any detail. Thus, it remains unknown how mutations alter STAT3 activity to drive blood cancers. In fact, the same can be said of most oncogenes. The capacity to identify mutations far exceeds the capacity to appraise them. Our research will directly address this problem. To that end, we have devised an experimental platform that enables us to study all known STAT3 mutations at once. This platform is scalable, new mutations can be easily added, and readily adaptable to other cancer drivers. It is also designed to be implement in mice, allowing us test drugs in vivo, across all mutants at once. Using this platform, we will advance basic understanding of STAT3 and inform treatment options for associated blood cancers.
Diffuse large B-cell lymphoma (DLBCL) is a common and aggressive type of malignant B-cell tumor. Despite progress in lymphoma treatment, up to 40% of patients will ultimately succumb to their disease. Chimeric antigen receptor (CAR) T-cells (CAR-T) are immune cells from patients where a patient’s own white blood cells are isolated and engineered to target and kill tumor cells. CAR-T cell therapies demonstrated an entirely new paradigm for cancer therapy and produced unprecedented initial responses in patients of relapsed or refractory DLBCL. However, our group and others recently observed that over half of patients on CAR-T therapy eventually had disease relapse and fatal progression due to development of resistance. Thus, there is an urgent need to improve the efficacy of response and delay or prevent CAR-T therapy resistance. To tackle this major obstacle, my group has developed sophisticated models and expertise to develop a novel strategy to target the tumor in a more precise, personalized manner to overcome chemo-, targeted- and CAR-T therapy resistance. Ultimately, we will rationally design and test the improved and safe combinations of CART with the newly discovered inhibitor for DLBCL therapy. The outcomes of this study have broad applicability 1) improve the current standard of care by overcoming refractory and relapsed DLBCL current therapy resistance, 2) enhance the CAR-T therapy efficacy, and 3), we anticipate, can be readily translated to improve quality of life and/or length of life and has immediate impact on DLBCL patient care.
North Carolina (NC) has the largest American Indian (AI) population east of the Mississippi River. Yet, we do not know much about the health and health care of AIs in NC. We do know cancer is their number one cause of death. We need to better understand cancer and cancer-related needs in this group to reduce the burden of cancer. Three NC cancer centers joined together in 2021 to learn more about how to help AIs with cancer. We will study how cancer of the liver and stomach affects American Indians in NC. And we want to find and create resources for our AI community. First, we will use the NC Cancer Registry and health insurance files to learn more about how and where AIs in NC get cancer care and any potential disparities. We will then have a community event to test for and treat the top cause of stomach cancer. Lastly, we will educate about liver and stomach cancer to help prevent them. This work will help AIs in NC by showing what the greatest needs are and the opportunities for better care. The long-term goal is to improve cancer outcomes in all AIs.
