Diffuse Intrinsic Pontine Gliomas (DIPGs) comprise the most lethal pediatric cancers, being almost completely unresponsive to chemotherapy and intractable for surgical removal. Dr. Reinberg and colleagues found that DIPG cells have an unusual "epigenetic signature" that contributes to their malignancy and have also identified the function of proteins that specifically recognize and translate this epigenetic feature. They are working on a novel therapeutic intervention for DIPGs that entails the identification/generation of reagents that specifically inhibit these proteins from functioning at this DIPG-associated epigenetic signature.

This grant is named for the Making Headway Foundation, a St. Baldrick's partner, whose mission for the past 20 years has been to provide care and comfort for children with brain and spinal cord tumors. The Foundation provides a continuum of services and programs while also funding medical research geared to better treatments and a cure.

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.

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.

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.

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.

Outcomes for children with acute lymphoblastic leukemia (ALL), the most common pediatric cancer, are dependent on age, biological subtype, and early response to therapy. Survival for certain subgroups have improved by intensifying therapy. Patients with persistent leukemia after the first month of therapy have an increased risk of future relapse, regardless of underlying leukemia subtype or treatment protocol. Therefore, patients with even low levels of persistent leukemia receive intensified therapy to induce complete molecular remission prior to stem cell transplant, making therapeutic targeting of low level residual leukemia important in the frontline setting. However, the biological features of this minimal residual disease have not been assessed and therefore precision approaches are currently out of reach. Understanding the biology of residual leukemia has critical implications for ongoing therapy. Vulnerabilities specific to leukemia cells that have survived during the early phases can be an avenue for future clinical trials for this population of patients. The biology of these rare leukemia cells may also be a window into the broader dynamics of ALL eradication. Even in cases with great responses to induction therapy with no detectable disease, patients require years of therapy to reduce the risk of relapse, demonstrating the residual leukemia cells are present. Such undetectable residual leukemia likely has similar biology to low level residual leukemia. Dr. Alexander is combining proven clinical tools that carry rich prognostic information, with flow cytometry approaches to isolate rare leukemia cells, and to utilize novel genomic tools including single cell analysis to describe the biology of residual leukemia.

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.

Malignant brain tumors are the most common cause of cancer-related death in children. The current standard of care treatment is often associated with lifelong cognitive and motor deficits and is almost inevitably followed by disease recurrence. Therapies that specifically and efficiently target tumor cells and minimize toxicity to normal cells are thus critical to the next generation of interventions that promise improved clinical outcomes for children affected by these deadly diseases. Capitalizing on our current knowledge of tumor metabolism and how metabolic pathways affect immune response, Dr. Deleyrolle is testing an innovative therapeutic modality based on reprograming the metabolic qualities of anti-tumor immune cells to enhance immunotherapy for childhood cancer. Successful completion of this project will demonstrate that immunometabolism represents a viable and critical target for the development of new cancer therapies to treat pediatric cancers, especially brain tumors. Dr. Deleyrolle is the recipient of the Pray for Dominic St. Baldrick's Research Grant. This grant is funded by the Pray for Dominic Hero Fund which was established in honor of an amazing boy who had so much joy and compassion for others even in a difficult battle with a rare and aggressive cancer. This fund carries on Dominic's legacy of joy and hope by funding research for high grade gliomas such as glioblastoma and DIPG for which there is no cure.

This grant is named for the Pray for Dominic Hero Fund. The fund was established in honor of Dominic Liples who lived with joy. He is remembered for compassion and determination while he faced his own difficult battle with a rare and aggressive brain cancer. The Pray for Dominic fund carries on Dominic's legacy of joy and hope by funding research for high-grade gliomas.

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.

Altering chemotherapy, including dose intensification, has not improved the survival for osteosarcoma (OS) patients. Genomic analysis has been unsuccessful in identifying consistent targetable options, and there were no responses in relapsed/refractory OS patients treated in numerous Phase I or II trials. Identifying new therapies is imperative. Immunotherapies such as dendritic cell vaccines (DCV) and checkpoint inhibitors have shown activity against adult cancers but there are no studies in children or adolescents (AYA) with OS. Dr. Kleinerman and colleagues demonstrated the efficacy of checkpoint inhibitor therapy against OS lung metastases. They have also showed that the activity of DCV can be improved by checkpoint inhibition. They are investigating whether a unique dendritic cell vaccine that augments T-cells is effective against primary and metastatic OS. This project aims to identify new therapeutic approaches for treating children and AYAs with relapsed/metastatic and primary OS. If efficacy is demonstrated, this approach can be translated into a clinical trial for children with OS lung metastases. Another goal is to combine vaccine therapy with chemotherapy for newly diagnosed patients to improve disease-free survival.

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.

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.

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.

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.

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.
