Childhood leukemia patients diagnosed with MLL rearranged leukemia (MLL-r) have a particularly poor outcome. MLL-r cells are dividing endlessly, due to the constant growth signal sent by a protein located on the cell surface called FLT3. FLT3 signals can be regulated by chemically modifying the protein in a variety of ways. Dr. Li is exploring a novel way to regulate FLT3 by studying how the activity of FLT3 is regulated by PRMT1 mediated methylation, and evaluating whether a PRMT1 inhibitor in combination with the traditional FLT3 inhibitor could completely "turn off" survival signal of MLL-r leukemia.

Thanks to advanced diagnosis and treatment, many children now can be treated from cancer and stay alive for a long time; they are called survivors. Some anticancer drugs are harmful to the heart and may cause heart failure in these survivors. High blood pressure increases the risk of heart failure in survivors, but no one knows how this happens. Dr. Zordoky has developed a new model to answer this question. He thinks that anticancer drugs make the hearts age faster leading to a worse response to increased blood pressure. He is looking at a natural compound and a new group of drugs which prevent aging to see if they will protect the hearts from the bad effects of anticancer drugs and make the hearts stronger when hit by high blood pressure. The findings of this research will open the door for testing these compounds in the clinic in order to prevent late side effects of anticancer drugs in survivors.

Acute lymphoblastic leukemia (ALL) is the leading cause of cancer-related death in young people. The high-risk ALL is a subtype of ALL that fare a high rate of relapse and mortality. Intriguingly, high-risk ALLs show increased signaling response to growth factors that results in uncontrolled cell proliferation, a block in normal B cell development, as well as a loss of tumor suppressor genes. Currently, the field is hampered by a lack of models that closely resemble human high-risk B cell leukemia for discovery of novel therapeutic therapies. Dr. Tong has generated novel models that closely resemble human high-risk B cell leukemia that are amenable for downstream applications. She is now using these novel models to perform a genome-wide genetic screen to identify novel targets to eradicate B-ALL proliferation. Furthermore, she is working to discover druggable signaling pathways that confer resistance to existing ineffective therapies. Therefore, this work will likely provide new insights into therapeutic strategies in treating pediatric high-risk B-ALL.

Cancer associated with different types of lymphocytes is known as lymphoma. Different forms of lymphoma are a common cause of pediatric cancer in the US. Current clinical therapy is based on conventional chemo- and radiation therapy, which is associated with numerous side effects.

As the recipient of the Jack's Pack - We Still Have His Back St. Baldrick's Research Grant, Dr. Bahal is researching an alternative robust therapy against lymphoma by exploring new chemically modified therapeutic molecules and their interaction with novel targets. One of the major challenges associated with current therapies are side effects due to non-targeted delivery of the drug to the normal bystander cells that can result in potential toxicity. Dr. Bahal is using a nanotechnology based approach for targeted delivery. He aims to accomplish two specific goals: a) To optimize the design and synthesis of a new class of bioactive molecules to target pediatric lymphoma; and b) To test the therapeutic effect of synthesized molecules in disease-related models. Investigation of these novel methods will lead to the development of novel drug candidate for pediatric lymphoma. Jack Klein was a 10 year old who loved life, laughing and monkeys. During his illness, his community of family and friends near and far rallied around him under the moniker "Jack's Pack". Their slogan was "We have Jack's Back". After Jack succumbed to Burkitt's Lymphoma, his "pack" focused their energy and efforts to funding a cure...just as Jack would have wanted.

Leukemias are the most common cancer of childhood, and most often arise from cells of the B lymphocyte lineage (B cell precursor ALL, or B-ALL). While the prognosis for patients with standard-risk disease is good, the treatment of patients with relapsed or refractory B-ALL is difficult and thus new therapies are needed. Dr. Schuettpelz is studying the role of a cell-surface protein called CD53 in the regulation of malignant B cells. CD53 is more highly expressed on leukemia cells than on normal B cells, and has previously been shown to promote the survival of malignant cells. Using a model of B-ALL as well as human leukemia cells, she will test the effects of CD53 loss and gain on disease development and cell survival. Ultimately, she hopes that CD53 may be targeted therapeutically to treat patients with B-ALL.

For children with pediatric brain tumors radiation therapy has been the backbone of treatment, in combination with surgery and chemotherapy. Although pediatric brain tumors can be highly responsive to radiation its use needs to be limited since radiation can be damaging to the brain, causing abnormal inflammation and long-term cognitive deficits that will profoundly impact the lives of patients. As the recipient of the Benicio Martinez Fund for Pediatric Cancer Research St. Baldrick's Research Grant, Dr. Sredni and her colleagues have identified a new drug (MW151) that can be given orally to patients receiving radiation therapy and can protect their brains against the cognitive decay caused by radiation. They are about to start a clinical trial, funded by the government (NIH/NCI), associating MW151 to whole brain radiation for the treatment of adults with brain metastases. Her goal is to move this approach to the pediatric population. This project is performing experiments that will test if inhibiting neuroinflammation with MW151 will interfere with brain tumor's response to radiation. This information is crucial to allow them to move forward with the studies necessary to use this protective drug in children. This new drug candidate has the potential to provide a safe and effective new adjunct protective treatment strategy. It can potentially transform the care and significantly improve the quality of life of our young patients and their families. Weeks after being the top fundraiser in his 6th grade class and shaving his head at his school’s event, Benny was diagnosed with medulloblastoma. Despite complications from treatment and setbacks, Benny has an amazing can-do attitude and is battling the cancer with determination.

This grant is funded by the Hero Fund that honors Benny’s fight and supports cures and better treatments for kids like him.

Unlike many other pediatric cancers, osteosarcoma has many abnormalities found on genetic analysis of the tumor itself. Dr. Sweet Cordero and colleagues hypothesize that some of these abnormalities could be used to predict what treatment might work best for each specific osteosarcoma patient. For example, many osteosarcomas have genetic alterations that block their ability to "repair" their DNA using specific pathways. One of these defective pathways is called the "homologous repair" pathway and another is called the "alternative lengthening of chromosomes" pathway. The inability of osteosarcoma tumors to repair their DNA using these pathways may make them susceptible to specific drugs. However, it is very likely that these drugs will need to be used in combination and not alone. A key need to advance osteosarcoma patient care is to define and use appropriate model systems to test drugs before using them in patients. This project is combining both preclinical studies in PDX models and a clinical trial to develop new ways to treat osteosarcoma patients with the goal being to improve survival for patients with relapsed and metastatic disease.

This multi-year grant is named for and funded by the Battle Osteosarcoma Hero Fund inspired by and established in honor of Charlotte, Dylan, Tyler and all OsteoWarriors. Led by parents, its mission is to raise funds for promising osteosarcoma precision oncology research to improve treatment options and outcomes for kids battling osteosarcoma.

The shape and function of bone, fat, muscle, and other connective tissues evolve through a carefully orchestrated process that leads mesenchymal stem cells (MSCs) to progressively differentiate into more lineage-restricted tissue-specific phenotypes. As this occurs, MSCs must interpret their surrounding extracellular milieu. When everything works correctly, normal mesenchymal tissues emerge. When disrupted, as tragically occurs with Ewing sarcoma (ES), the aberrant fusion protein (FP) acts as powerful transcription-factor that corrupts the epigenetic program and locks ES in an undifferentiated state unable to interpret or respond to the biophysical cues present in the tumor microenvironment. Attempts to understand the FP’s effect upon tumor-ECM interactions within monolayer culture systems that lack a native tumor microenvironment has contributed, not unexpectedly, to spurious results that overestimate the clinical effectiveness of chemotherapy. To close this gap, Dr. Ludwig's multi-disciplinary team is using an innovative 3D tissue engineered model, pioneered by his laboratory, to assess next-generation EWS-FLI1-targeted therapies within a physiological microenvironment that cannot readily be studied in vivo. This project will shed new light on ES biology and promises to improve the ability to co-target the FP and other proteins that maintain the aggressive, poorly differentiated state of ES.

This grant is generously supported by the Shohet Family Fund for Ewing Sarcoma Research. Noah was diagnosed with Ewing sarcoma in his freshman year in college. After limb salvage surgery and chemotherapy, he was able to return to school. Two years later, Noah relapsed. This Hero Fund honors his courageous fight and hopes to raise funds for Ewing sarcoma research.

Malignant rhabdoid tumor (MRT) and atypical teratoid/rhabdoid tumor (AT/RT) are rare but devastating childhood cancers. Most children diagnosed with MRT and AT/RT are under the age of two, and most will die from their disease despite intensive treatment interventions. New insights into what causes these cancers, and new therapies, are desperately needed. Genetically, MRT and AT/RT are simple cancers, caused by loss of just one gene called SMARCB1. If we are to understand and treat MRT and AT/RT, therefore, we need to understand how loss of SMARCB1 causes cancer.

As the recipient of the Oh Danny Boy I Love You So: The Danny O'Brien Rhabdoid Tumor Research Fund St. Baldrick's Research Grant, Dr. Tansey is working on an innovative molecular mechanism through which loss of SMARCB1 causes MRT and AT/RT. He proposes that these mutations drive cancer by stimulating the activity of a known pro-tumorigenic gene called MYC. Dr. Tansey further proposes that MRT and AT/RT can be effectively treated by drugs that block the actions of MYC, currently being developed by us and others. He is testing this model and exploring its therapeutic implications. Completion of this work has the potential to transform the understanding of how MRT and AT/RT form and how they can be treated. Danny O’Brien was five months old when he was diagnosed with a rare malignant rhabdoid tumor on his liver. Despite treatment to shrink the tumor, he passed away at the tender age of 9 months. Fortunately, he knew nothing but love and affection for all of his short life. This fund honors Danny’s courage and remembers his unconditional love in the midst of his battle with cancer.

We can now manipulate the immune system with remarkable precision and efficacy to fight certain cancers. However, tumors adapt to reduce immunotherapy efficacy. This is true for solid tumors including osteosarcoma. Therapy-refractory metastatic osteosarcoma represents a pressing unmet need, as the outcome has not improved for over 3 decades. This multi-institutional collaborative proposal explores tumor-extrinsic pathways by which pulmonary metastatic osteosarcoma evade immunity. Dr. Huang’s team is focusing on key molecules responsible for such evasion, against which existing or emerging therapeutic agents are available currently or in the very near future. Therefore, uncovering these pathways could realistically offer multiple new clinical trials for pediatric and AYA metastatic osteosarcoma in the next 3 years. This Osteosarcoma Collaborative St. Baldrick's Grant to Cure Osteosarcoma is funded through the generosity of the Osteosarcoma Collaborative.

Nearly half of all children diagnosed with Acute Myeloid Leukemia (AML) will suffer a relapse after initially successful treatment. Whereas therapy efficiently clears the bloodstream of leukemia cells, frequent evidence of residual drug resistant disease points to a leukemia protective role of the bone marrow microenvironment. The mechanism by which the bone marrow acquires these protective abilities is not clear. Dr. Kurre recently observed that so called stroma cells, that provide bone marrow structure and support are functionally altered. Pilot studies conducted by Dr. Kurre also identified a new mechanism by which AML changes these stroma cells. In this project Dr. Kurre is studying pediatric AML samples to understand how the altered stroma protects leukemia cells from the effect of drugs commonly used to treat children with AML. The long term goal is to develop treatment approaches that reduce the burden of relapse, by maintaining initial remissions in children with AML, and without further escalating drug toxicity. Awarded at Oregon Health and Science University, and transferred to The Children's Hospital of Philadelphia.

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

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.

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.

Millions of cells are formed every day in the developing brain of children. Medulloblastoma, a pediatric tumor, occurs when the proliferation of cells in the cerebellum (a lower part of the brain) becomes uncontrolled. The Notch pathway is a key mechanism that governs cell proliferation in many biological contexts. Aberrant up-regulation of Notch signals is associated with medulloblastoma. Re-gaining control of Notch could help cure medulloblastoma patients. As the recipient of the Hope for Daisy Research Fund for Pediatric Brain Tumors St. Baldrick's Research Grant, Dr. Rual's goal is to better understand the molecular mechanisms that control Notch signals in brain cells and, thus, to define novel therapeutic targets for the benefit of medulloblastoma patients. He recently identified the L3MBTL3 gene as a new modulator of Notch signals. Importantly, previous studies have shown that the L3MBTL3 genes is deleted in medulloblastoma patients. Dr. Rual hypothesizes that the L3MBTL3 deletions observed in medulloblastoma patients result in the aberrant regulation of Notch signals, thus supporting tumorigenesis. Dr. Rual's team will test this hypothesis by studying the extent to which inhibiting L3MBTL3 modulate medulloblastoma tumor progression in models of medulloblastoma. This study could offer critical mechanistic insights on the role of the L3MBTL3 in medulloblastoma that could be harnessed in the future for the therapeutic benefit of medulloblastoma patients.

This grant is funded by and named for the Hope for Daisy Research Fund for Pediatric Brain Tumors, a St. Baldrick's Hero Fund. Diagnosed with medulloblastoma at the age of six, Daisy Walsh met the challenge head on with joy, strength and laughter. Days before her eighth birthday, the tumor recurred and despite her brave battle, Daisy passed away in February 2020. This fund honors her courageous spirit by helping to raise awareness and funds for research to increase survival rates and hope for all children battling brain cancer.

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.

The goal of Dr. Riehle's research is to find a cure for a rare form of liver cancer that occurs in children and young adults, called fibrolamellar hepatocellular carcinoma (FL-HCC). Unfortunately, surgery is currently the only effective treatment option for these patients, and once the disease has spread outside of the liver there is no chance for cure. Dr. Riehle's laboratory has spent the last few years trying to understand what changes within the liver cause healthy kids to get this cancer, and has developed a couple of new models of FL-HCC that can be used for drug screening. In this project she is using these models to test new treatment options and to try to understand how this cancer develops.

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.

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.

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.
