Clinical trials help improve the treatment of children with cancer. But, it takes a lot of work to be able to offer clinical trials to patients. This grant will help us add another person our research team part-time. This person will gather information about clinical trials and share it with patients, families, and other providers so that people know what we have available at Duke. They will work with other doctors at Duke who treat children and young adults with cancer to make sure we are all offering clinical trials to our patients. They will also follow up with survivors of pediatric cancer to let them know of any available research options. By doing these things, we hope to be able to offer clinical trials to more patients.

We are developing a new cancer treatment that could change how we fight the disease. Our drug, FM-FolamiR-34a, is designed to treat triple-negative breast cancer (TNBC). TNBC is one of the most aggressive and hardest-to-treat types of cancer. Many cancer treatments attack a single target, but our drug works differently. It stops multiple targets at once, like a combination of drugs in a single treatment. It does this by replacing a natural tumor-fighting molecule that is missing in many TNBC cases.Earlier attempts to use this type of treatment failed because the drug broke down too quickly and did not reach tumors well. We have solved this problem by making the drug more stable and attaching it to a targeting molecule that guides it directly to cancer cells.In lab studies, this approach shrank tumors and, in some cases, made them disappear completely. To prepare for human trials, we will improve the drug, compare it to existing treatments, and complete important safety tests.This research could lead to a powerful new way to treat cancer, offering hope to patients who currently have few options. Our goal is to turn cutting-edge science into real treatments that save lives.

Glioblastoma is the most common and aggressive type of brain cancer, and sadly, most people only survive 12 to 18 months after being diagnosed. This hasn’t changed in the last 20 years. One of the reasons it’s so hard to treat is that glioblastoma is very complex and different from one patient to another.To improve treatment, we need to better understand this complexity and figure out how to target each part of the cancer. The Suva lab has spent the last decade studying glioblastoma in depth using advanced genetic tools to understand how it varies. We’ve discovered that glioblastoma can be broken down into four important parts, and each part is essential for the cancer to grow.In this research, we will develop strategies to target each of these four parts. We’ll use new technologies developed by the Bar-Peled lab that can target elements of the cancer that were once thought too hard to treat. Our first step will be to analyze tumor samples from patients to find new drug targets. From there, we will work on drug development to eventually test them in clinical trials.

Lung cancers are often discovered after they have spread throughout the body. When this happens, patients must be treated with drugs. These drugs often shrink tumors but do not cure patients. The tumor cells that survive these drug treatments are known as “residual” cells. Residual cells eventually grow back, causing death. For this reason, we are very interested in discovering drugs that can kill residual lung cancer cells. Recently we discovered that residual lung cancer cells cannot survive without an enzyme called PKN2. We have access to a drug that blocks PKN2. Further, we already know that this drug is safe for patients. We are applying for grant funds to do three things. First, we will determine which residual lung cancers are most sensitive to this drug. Second, we will determine how this drug kills residual lung cancers. Third, we will determine how well this drug prevents lung cancer from relapsing in mice. Together, these studies will advance our understanding of residual lung cancer. They will also advance a new drug therapy that can be quickly translated to clinical trials by our team of expert doctors and scientists.

After successful treatments, cancer patients often dread their disease returning months or years down the road. Even a few cancer cells hidden in the body can find ways to grow again. We will find ways to block these cancer cells from mutating so that they cannot find ways to grow again. These studies seek to provide new ways to extend survival and improve quality of life.

Multiple myeloma is a type of cancer that affects plasma cells. This disease can lead to infections, kidney problems, and bone pain or fractures. There have been great improvements in the treatment of multiple myeloma in recent years. However, most people are still not cured by current therapy. Treatments that use the immune system have shown great promise. One important example is CAR T-cell therapy. CAR T cells are made by taking a patient’s T cells (a type of immune cell), and changing them so they can recognize and kill cancer cells. These cells are then given back into the patient by an intravenous infusion. CART cell therapy has resulted in dramatic improvements in outcomes for patients with multiple myeloma. Our group has studied a new combination approach to improve upon responses to CART cell therapy. We have developed a personalized cancer vaccines using a patient’s own cancer cells. To make the vaccine, a patients plasma cells are collected from the bone marrow and are combined with immune cells called dendritic cells, which help activate the immune system. In a national study, this vaccine was shown to be safe, could be made at centers across the country, and was shown to stimulate immune responses. In this new study will test the vaccine in combination with CAR T-cell therapy. This DC/MM fusion vaccine has the potential to stimulate a broad immune response, preventing the development of resistance and can expand the CART cells to enhance their durability and effect.

The Southeastern American Indian Cancer Health Equity Partnership (SAICEP) is a team made up of three cancer centers in North Carolina. These centers are working together to help lower cancer rates in American Indian communities. This year, with help from the V Foundation, SAICEP is starting a new project for Native youth and young adults, ages 16 to 30. The goal is to lower the risk of cancer by focusing on three things: getting the HPV vaccine, staying safe in the sun, and stop the use of unsafe tobacco products. To do this, SAICEP will work with the North Carolina Native American Youth Organization (NCNAYO). They will choose and train Native youth to become health ambassadors. These ambassadors will share important health information in their communities. SAICEP will also go to Native events across the state to talk with people and hand out materials about cancer health. At the end of the project, they will ask the youth and others what they learned and how the project helped. This project will help more young Native people stay healthy and avoid cancer in the future. It also gives Native youth a chance to lead and help their own communities.

Acute Myelogenous Leukemia (AML) is a fast-growing cancer of the blood and is the most common type in adults. Unfortunately, current treatments often don’t work well, and many patients get sick again or die. That’s why new and better treatments are needed. In our research, we looked at a protein that is found in large amounts on the outside of leukemia cells. Our earlier studies showed that this protein is needed for the cancer to grow. Because it’s on the outside of the cell, we can try to block it using special tools called antibodies. These antibodies attach to the protein and stop it from working. Here, we propose to develop an antibody that is able to target the protein and stop the cancer cells from growing. If we are successful, we plan to test the antibody in patients who are newly diagnosed or who haven’t gotten better with current treatments. This new antibody treatment could be a powerful new way to help people with AML live longer and healthier lives.

Immunotherapy is a type of cancer treatment that helps the body’s immune system fight cancer. It has changed how we treat many cancers. But not all patients benefit from it. So, we need new ways to make this treatment work better. One area of interest is the gut microbiome. This is the group of trillions of bacteria that live in our gut. These bacteria can affect how the immune system works and how well immunotherapy works. Our research, and that of others, has shown that people who respond to immunotherapy have different gut bacteria than those who do not. Diet plays a big role in shaping the gut microbiome, as the bacteria in our gut eat what we eat. We have shown that diet is linked to how well people respond to immunotherapy. In mice, changing the diet changed both the gut bacteria and the response to treatment. Now, we are testing if diet changes can help patients who are starting immunotherapy. We want to see if we can improve their gut bacteria and boost their immune response through their diet. If this works, it could be a simple and low-cost way to help more people benefit from immunotherapy. We also found that a plant-based, high-fiber diet lowers certain bile acids in the body; these acids may weaken the patient’s immune response. In this study, we will test if these bile acids can be used as a marker of the extent to which the diet and treatment are working.

Women with excess body weight are more likely to get breast cancer than women with a healthy weight. The effect of excess body weight is especially harmful to women with a family history of breast cancer. Excess body weight can cause many harmful effects to cells. By limiting or reversing these changes, we may be able to prevent breast cancer. We think that exercise or weight loss can decrease the risk of breast cancer by reducing damage to cells. This is very important as it may provide options for women who decide not to get prevention surgery. In the future, we will apply what we have learned to a clinical trial.
