Radiation therapy is an important tool in the treatment of childhood cancer. Radiotherapy not only makes tumors shrink, it also causes inflammation of the tumor and can make immune cells attack the cancer. However, tumor cells can secrete substances that prevent immune cells from killing cancer cells. In addition, certain immune cells, called regulatory T cells (Treg) and myeloid derived suppressor cells (MDSC), exist to prevent an overshooting immune response. These cells are recruited to inflamed tumor tissue and dampen the anti-cancer immune response. To overcome this problem, Dr. Otto is testing a drug in combination with radiotherapy that has shown to reduce or deplete immunosuppressive cells from tumors, and lead to increased numbers of cancer killing immune cells in the cancer tissue. In models of pediatric cancer, he is combining this drug with a particular form of radiotherapy, called radionuclide therapy that uses radioactive substances which are injected into the bloodstream to carry their radioactive load directly to tumor cells. Dr. Otto hopes that this combination therapy will lead to robust and long-lasting anti-cancer effects.

This grant is made with generous support from the Team Campbell Foundation, established in memory of Campbell Hoyt, who courageously battled anaplastic ependymoma, a rare cancer of the brain and spine for five years. Its mission is to improve the lives of families facing a childhood cancer diagnosis through raising awareness, funding research and providing psycho-social enrichment opportunities.

This year it is estimated that 800 children will be diagnosed with osteosarcoma. It is thought that sex hormones play a role in the onset of the disease, as more boys than girls get osteosarcoma and the cancer develops at the time of puberty. Dr. Miranda hypothesizes that a key molecule in estrogen signaling is turned off in osteosarcomas, preventing those cells from being normal bone. Her preliminary data shows that she can turn back on that key estrogen signaling protein. These drugs have not been tested in osteosarcoma patients, but are FDA-approved drugs, so they could provide a treatment for osteosarcoma patients in the immediate future.

This grant is generously supported by the Sweet Caroline Fund created to honor the memory of Caroline Richards who was diagnosed with osteosarcoma at age 11. She persevered through rigorous treatments with a giving spirit and a contagious smile, always thinking of how to make others happy or laugh. This fund pays tribute to her compassion for others by supporting osteosarcoma research to help kids with cancer

Rhabdomyosarcoma (RMS) is a cancer with features of skeletal muscle, and the most common soft connective tissue cancer of childhood. The alveolar variant of RMS (abbreviated ARMS) is particularly hard to cure. If we could figure out which proteins in ARMS cancer cells work together to drive this cancer, we might also be able to figure out which are good drug targets. A common genetic error in ARMS is the mutant protein PAX3-FOXO1, which turns on cellular programs that cause ARMS cells to keep dividing. However, PAX3-FOXO1 is not a good drug target, and it does not work alone – it physically interacts with other proteins that carry out its cancer-causing instructions. Here, Dr. Linardic and colleagues will use a sophisticated new method to identify proteins in PAX3-FOXO1’s cellular neighborhood, a rapid screening technology to figure out which are most crucial to ARMS, then use models of ARMS to see which of the proteins might be the best drug targets. Importantly, this project will be carried out by three research teams with unique but complementary skills working together, united in a mission to find new therapies for this difficult-to-cure cancer.

As the recipient of the Rosa and Francesco Romanello St. Baldrick's Research Grant, Dr. Lawlor is studying an aggressive tumor called Ewing sarcoma that occurs most often in teenagers. It usually starts in a bone and then can spread or metastasize throughout the body. Once it has spread, the chances of cure are very poor. She is studying how the tumor cells change the surrounding normal tissues to allow the tumor cells to leave the bone and spread to other sites in the body. Results so far have shown that the tumor cells and the normal tissues "talk to each other" and that this crosstalk is likely to be essential for the growth and spread of the tumor, both within the bone as well as in other tissues. Dr. Lawlor will decipher these messages, and the instructions they convey, so that new therapies can be developed that will intercept them and block tumor spread.

This grant is named in recognition of Salvatore Romanello for his decade of service as pro bono general counsel to the St. Baldrick's Foundation. He has chosen to name the grant in honor of his parents who instilled in him the values of generosity and caring for a greater cause.

Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant brain tumor that has a very poor prognosis despite aggressive treatment. The development of new, effective therapeutic approaches for AT/RT has been hindered by a lack of specific therapeutic targets. It is necessary to find effective therapeutic targets, preferably based on the understanding of the molecular mechanisms that promote this highly malignant brain tumor. A tumor suppressor gene (SMARCB1) is absent in the majority of AT/RT and loss of this gene leads to factors that promote tumor growth. This research involving genetic and pharmacologic inhibition of histone binding proteins (EZH2 and BRD4) is of high importance for developing effective therapies for pediatric patients with AT/RT. Dr. Hashizume will determine whether therapeutic combination of targeting two histone binding proteins, BRD4 and EZH2, provides synergistic benefits, and will inform how best to maximize the clinical potential of combination therapy for effective treatment of children with AT/RT. This research will also test how tumors adapt to this molecular targeted therapy, to ultimately inform clinicians how to treat tumors that have resistance to molecular targeted therapy. Finally, this project will explore how this combination therapy interacts with radiation in treating AT/RT, which is important due to the frequent use of radiation in treating AT/RT.

This grant is generously supported by the “Just Do It…and be done with it” St. Baldrick’s Hero Fund created in honor of Sara Martorano who was four years old when she was diagnosed with Stage IV Wilms tumor. Thanks to research, today she is cancer free. This fund celebrates the courage of cancer kids through treatment and the support of their family and friends.

Although many children being treated for cancer initially respond to therapy, cancer cells often become resistant to chemotherapy drugs. Drug resistance is a major cause of cancer relapse, recurrence, and treatment failure. Dr. Gordon's goal is to identify new approaches to block, or reverse, resistance to an important class of cancer drugs. He has already identified one approach to reverse resistance in the laboratory, which he is now testing in models of cancer. Dr. Gordon is also testing a large number of additional drugs for the ability to prevent or reverse resistance.

The immune system acts as the body's defense against cancer by recognizing and attacking cancer cells. However, cancer cells have devised strategies collectively called "immune evasion," to thwart these protective mechanisms, making it difficult for immunotherapies to be fully effective.

As the recipient of the Emily Beazley Kures for Kids Research Grant, Dr. George aims to understand how the MYCN gene, which is abnormal in over half of patients with high-risk neuroblastoma, can cause tumor growth by shutting off protective immune mechanisms. In her preliminary studies, she has observed that MYCN amplification is associated with genes that evade the immune response, but exactly how MYCN does this is not known. Dr. George will use a novel model to understand how abnormal MYCN enables tumor cells to evade the immune system. At the age of 8, Emily was diagnosed with Stage III T-cell lymphoblastic non-Hodgkin’s lymphoma and battled through three relapses. Her family prayed for a miracle but discovered Emily herself was the miracle, inspiring a community to come together to show love and change lives. She had a dream of starting a foundation to fund research and named it “Kures for Kids”. Today, Emily's family and friends carry on her dream and her mission in her memory.

NUT midline carcinoma (NMC) is a deadly cancer that affects children and young adults, with a survival of less than 7 months. NMC is caused by a protein called BRD4-NUT that changes the structure of DNA in such a way that the DNA drives expression of cancer-associated genes that promote growth of NMC. Dr. French proposes to determine what is actually happening to the structure of the DNA that allows it to express the cancer-driving genes. There are two protein types he suspects are helping BRD4-NUT distort the DNA conformation; these are called HDACs and HATs. Dr. French's team will use state-of-the-art inhibitors that target specific HDACs and HATs to determine their respective roles and help identify novel therapeutics to treat this incurable disease.

Leukemia is a blood cell cancer that frequently affects children. Despite the advances in treatment options, children with certain subtypes of leukemia are resistant to current therapy. Novel therapy for childhood leukemia is urgently needed. Dr. Fang's team recently found a protein, whose name is GPR68. They found that the levels of GPR68 were increased in blood cells of leukemia patients. When they decreased GPR68 levels, leukemia cells died, suggesting that increased GPR68 helped leukemia cells survive. Interestingly, normal blood cells with reduced levels of GPR68 were normal, suggesting that only leukemia cells need GPR68. Dr. Fang's findings suggest that lowering GPR68 levels or limiting its function may help cure leukemia without injuring normal blood cells. As the recipient of the Emily Beazley's Kures for Kids Fund St. Baldrick's Research Grant, she will be working to understand the function of GPR68 in leukemia cells and normal blood cells, and test drugs that could cure leukemia by inhibiting GPR68 function.

This grant is funded by and named for Emily Beazley's Kures for Kids Fund, a St. Baldrick's Hero Fund. At the age of 8, Emily was diagnosed with Stage III T-cell lymphoblastic non-Hodgkin’s lymphoma and battled through three relapses. Her family prayed for a miracle but discovered Emily herself was the miracle, inspiring a community to come together to show love and change lives. She had a dream of starting a foundation to fund research and named it “Kures for Kids”. Today, Emily's family and friends carry on her dream and her mission in her memory.

Neuroblastoma is a cancer formed in certain types of nerve tissue and is the most common pediatric solid tumor outside of the brain. It is the leading cause of cancer-related death in children under five years old. Those patients who do survive often develop long-term side effects from intensive chemotherapy and radiation therapy. Thus, we need to develop better, safer alternative therapies for neuroblastoma. Dr. Cripe is currently studying the use of genetically modified herpes viruses. These viruses, which include the recently FDA-approved herpes virus T-VEC, can selectively infect and kill cancer cells without harming normal cells. In addition, these viruses are also able to enhance the patient's immune response against the cancer cells, potentially leading to a systemic and long-lasting protective immunity against cancer dissemination and recurrence. In the course of his studies, Dr. Cripe found that tumors infected with virus induce a counter measure by attracting cells that suppress immunity. In this study, he will test if he can improve therapy by interfering with that counter measure. If successful, these results may lead to a novel clinical trial for neuroblastoma patients.

Current cancer therapy is very toxic and does not always work. We have developed a way to deliver much more drug to the tumor, and much less to the patient, by packaging the drug in properly designed nanomedicines. These delivery systems take advantage of the fact that most aggressive tumors have leaky blood vessels, so our nanomedicines can pass through into the tumor, but they bypass most normal tissues. Using these formulations, we can deliver 10-100 times as much drug to the tumor, so we can use less total drug and still get better results. In addition, Dr. Brodeur is using a novel drug called SN22. Although SN22 is related to a commonly used chemotherapy agent called irinotecan, it is an active drug, and unlike irinotecan it does not have to be activated by the liver. It is not only much more potent but also harder for the tumor cells to get rid of. These features make SN22 much more therapeutically effective. The carrier Dr. Brodeur is using to make this nanomedicine can deliver four molecules of SN22 within each “packet” that enters the tumor. Because he can use less total drug, and because the nanomedicine can circulate for a long time with the drug attached, there is much less exposure to the rest of the body, so side effects are dramatically reduced. As the recipient of the Invictus Fund St. Baldrick's Research Grant, Dr. Brodeur's goal is to develop more effective but less toxic therapy to treat children with cancer, and he can accomplish that goal with this approach using nanomedicine-based drug delivery. The nanomedicines he is developing should be effective against many different solid tumors in children or adults and he hopes to bring them forward to Phase 1 clinical trials.

This grant is funded by and named for the Invictus Fund, a St. Baldrick's Hero Fund created in memory of Holden Gilkinson and honors his unconquerable spirit in his battle with bilateral Wilms tumor as personified in the poem “Invictus” by William Ernest Henley. His family hopes to fund cures and treatments to mitigate side and late effects of childhood cancer.

Neuroblastoma is a cancer of the nervous system that causes aggressive disease in infants and young children, and the overall survival rate of high-risk (stage IV) patients is low. Ornithine decarboxylase (ODC) is a validated target in several cancers and we advanced the ODC inhibitor DFMO into neuroblastoma clinical studies. While promising, large quantities of DFMO are needed for patient treatments because about 80% of the drug is released into the urine. To improve the retention of DFMO in the blood, this study explores the combination of DFMO with an FDA-approved adjuvant. We expect that DFMO in the presence of this adjuvant will (a) increase the DFMO concentration in the blood and (b) induce more potent anti-tumor effects in neuroblastoma tumor-bearing mice. Since both DFMO and the adjuvant are FDA-approved drugs, this new regimen could rapidly advance to neuroblastoma clinical studies.

Pediatric undifferentiated sarcomas are highly aggressive cancers that typically affect soft tissues of young children. Due to their uncertain classification and lack of molecular signature there are no standard criteria for diagnosis or treatment. With the Alan's Sarcoma Research Fund St. Baldrick's Research Grant, Dr. Antonescu is applying state of the art genomic methods to provide a detailed genetic characterization in these orphan cancers and investigating driving chromosomal translocations or mutations involved in their growth. These results will establish an objective classification of these tumors based on their genetic abnormalities and will provide potential therapeutic targets for further novel therapies. Furthermore these findings will inform the generation of faithful models for studying sarcoma formation and new drug development.

This grant is funded by and named for the Alan's Sarcoma Research Fund, a St. Baldrick's Hero Fund. Alan Sanders was diagnosed with a rare sarcoma in his hip at 17 months. He had an indomitable spirit and throughout his 4 ½ year battle with cancer, he was joyful, upbeat and pressed on courageously in spite of surgery and treatments. Today his family and friends carry on his legacy and his rallying cry, “Fight’s on!” in the battle against childhood cancer by funding sarcoma research.

Phthalates are chemicals added to many products that we use every day, including some common medications. Phthalates interfere with hormone systems in our bodies, which might cause cancer. Dr. Ahern wants to know if phthalate exposure while in the womb or during childhood increases the risk of childhood cancer. It would usually be time-consuming and expensive to answer this question scientifically. However, Dr. Ahern's team has developed a way to measure phthalate exposure using electronic pharmacy records that is both fast and inexpensive. This technique works because phthalate exposure from medications dwarfs exposure from other products. He will use this technique on existing pharmacy and cancer data from the entire population of Denmark. Dr. Ahern will measure phthalate exposure in pregnant women and in their children, and calculate whether that exposure increases a child's chances of developing cancer. If he finds that it does, we could prevent childhood cancer cases by limiting the amount of phthalates used in consumer products.

In the U.S., children with a blood cancer called Hodgkin lymphoma (HL) are usually treated successfully. Some of these children will suffer health problems several years later because of the treatment they received. Because of this, doctors use powerful imaging tools to identify patients who are likely to do well or not. Those who are likely to do well require less treatment and those who are less likely to do well can receive more treatment. But in low-income countries like Malawi, these tools are unavailable, and the children there often receive treatment that may be unnecessary. Scientists have found unique abnormalities in adults with HL that can tell us who is less likely to do well. Here, Dr. Ozuah is testing whether these abnormalities are present in children and could be used to decide how best to treat children with HL in low-middle income countries

Osteosarcoma is the most common primary bone tumor in childhood. The survival rate remains dismal, mainly due to ineffective therapeutic approaches for the relapsed/metastatic patients. One major obstacle of treating osteosarcoma is lack of suitable preclinical models. Dr. He's studies have established the first cultured osteosarcoma tissue model (an organoid). Dr. He aims to establish the first biobank of osteosarcoma organoids from patients as an open resource for the field, and utilize this organoid biobank to evaluate a novel class of therapeutics targeting key signaling pathways in osteosarcoma cells. This study will provide a powerful platform for predicting clinical treatment responses and developing new therapeutics for treating osteosarcoma.

Cancer cells rely on specific nutrients for growth and survival, rendering nutrient restriction as a potential therapeutic strategy. Along this line, acute lymphoblastic leukemia (ALL) cells have been found to be dependent on exogenous supply of asparagine, a nonessential amino acid, for protein synthesis. As a result, depletion of asparagine in the blood stream by L-asparaginase, a chemo-agent, has been successfully used to treat pediatric ALL for 40 years. However, ALL patients can develop resistance to the continuous application of this chemo-agent. Dr. Zhang is determining how ALL cells become resistant to L-asparaginase treatment, and therefore to provide experimental evidence of novel therapeutic targets that can potentially improve the outcome in pediatric ALL patients.

Sarcomas are tumors of the bone and soft tissues that comprise up to 20% of cancer diagnoses in children. Despite dismal outcomes for patients with recurrent or metastatic disease, treatment regimens have remained largely unchanged for decades – intense non-specific chemotherapy combined with surgery or radiation. Dr. Tulpule studies Ewing’s sarcoma (ES), a bone tumor caused by a unique genetic change that creates a tumor-specific protein EWS-FLI1. To date, no drug has been identified to directly block the cancer causing EWS-FLI1 protein. His research takes a different approach to combating ES by asking a fundamental question: can we identify a targetable weakness in ES tumors that is caused by the EWS-FLI1 protein? Using a cutting-edge screening technology called CRISPR interference, Dr. Tulpule's team identified a specific vulnerability in ES cells’ capacity to repair damage to their DNA. Normal cells have many backup systems in place to repair DNA damage, but they have shown that EWS-FLI1 causes ES cells to become overly reliant on a single pathway, known as homologous recombination (HR) repair, such that blocking HR is an effective and specific way to kill ES. Dr. Tulpule is building a detailed understanding of why ES cells are so vulnerable to HR pathway blockade and then applying that knowledge towards developing less toxic and more effective treatments for ES patients.

Despite improvements in outcome for patients with acute lymphoblastic leukemia (ALL), up to 25% of children and 40% of adults fail frontline therapy and their prognosis is dismal, especially for high-risk and relapsed leukemia. Cure rates for ALL patients that are relapsing on therapy is approximately 20% and currently there are no targeted therapies. Dr. Tsirigos' goal is to address this significant clinical need by studying how DNA, our genetic material, is organized inside the nucleus of the cells, i.e. how it is folded in three-dimensional space. Over the past decade, seminal studies have demonstrated that DNA folding is of fundamental importance in that it allows the cell to properly perform its function and retain its identity (e.g. a liver cell versus a blood cell). Very recent studies have demonstrated that disruptions of DNA folding may cause various diseases, such as developmental defects and cancer. However, no study has addressed the question of disruptions of DNA folding on the genome-wide scale in cancer or how such disruptions may be exploited for more effective treatments. Dr. Tsirigos is attempting to answer two key questions. First, are cancer-promoting genes (“oncogenes) capable of disrupting normal DNA folding to transform normal cells into malignant ones? And, second, can drug treatment restore DNA folding and thereby also restore normal cell function?

This grant is made with generous support from the Rally for Ryan Fund. Ryan was diagnosed with high risk ALL when he was 7 years old. He endured 3½ years of treatments with a brave acceptance that this was his fight to win. He recently relapsed and is in the fight again. This fund honors Ryan’s perseverance and his commitment to make a difference for kids with cancer by shaving for St. Baldrick’s and raising funds for research.

Based on progress to date, Dr. Osborn was awarded a new grant in 2022 and 2023 to fund an additional year of this Scholar grant. Abnormal growth of B-cells can result in leukemia, and a cutting-edge treatment option is immunotherapy with T-cells. T-cells can be engineered to express a chimeric antigen receptor (CAR) that is a 'seek and destroy' molecule for the CD19 protein on B-cells. CAR T-cells are the first FDA approved gene therapy and some stunning therapeutic responses have been observed. However, the T-cell activity can be so robust that they cause a massive cytokine storm that can be lethal. Furthermore, normal and cancerous B-cells express the CD19 protein targeted by the CAR, so normal B-cell loss occurs resulting in an impaired immune system. These side effects represent a significant hurdle in the safe and effective treatment of B-cell leukemia. To address this, Dr. Osborn, will express the CAR in a specialized subset of cells called T-regulatory (Treg) cells. Tregs have the same potent killing ability as T-cells but accomplish it without healthy tissue collateral damage. Additionally, he will engineer functional B-cells that are invisible to the CAR. This will allow for normal B-cell numbers and an intact immune system. Dr. Osborn will conduct these studies that are structured to resolve an unmet need, are highly novel, and are poised to make an immediate impact on childhood leukemia. 

The 2022 portion of this grant is named for the Rays of Hope Hero Fund which honors the memory of Rayanna Marrero. She was a happy 3-year-old when she was diagnosed with Acute Lymphoblastic Leukemia (ALL). She successfully battled ALL, but a treatment induced secondary cancer claimed her life at age eight. Rayanna had an amazing attitude and loved life. She, like so many kids facing childhood cancer, did not allow it to define who she was. This Hero Fund aspires to give hope to kids fighting cancer through research.

A portion of this grant was funded by and named for the Mighty Mimi Hero Fund. Mimi Enyon was diagnosed with acute lymphoblastic leukemia at the age of 3. Her courage in the fight was unparalleled and she became “Mighty Mimi” to all those she inspired on her way to remission. This fund was established to share Mimi’s cancer journey in an effort to raise awareness and funding for childhood cancer research for kids like her.

A portion of this grant is generously supported by the Stanley Kuzmickas Feeney Fund for Pediatric Cancer Research. It was Christmas 2015 when Stanley was diagnosed with acute lymphoblastic leukemia at 13 months old. He courageously endured treatments for 3½ years. Today, he is in remission and eagerly started school in fall 2019. In his honor, Stanley’s family has organized a head-shaving event each year since July 2016 called “StoshyStrong." With the funds raised, the Feeney family created this Hero Fund to support research in new discoveries, genomics and other biological therapies for the treatment of ALL. Their goal is to one day see personalized treatments for every child.
