Xylitol Dental Wipes for the Reduction of Bloodstream Infection Risk in Children With Acute Myeloid Leukemia

This phase III trial compares the effect of xylitol dental wipes to dental wipes without xylitol for the reduction of bloodstream infection in children with acute myeloid leukemia (AML). Xylitol is a naturally occurring sugar compound found in fruits and vegetables. Xylitol has been shown to limit the growth of bacteria in the mouth, and to reduce cavities, plaque on the teeth, and inflammation of the gums. Treatment for AML includes chemotherapy. Patients receiving chemotherapy for AML have a risk of developing bloodstream infections. Bloodstream infections can make patients very sick, can contribute to delays in treatment, and can even cause death. In AML patients, bacteria or fungus (yeast) can sometimes enter the bloodstream from the mouth. Using xylitol dental wipes may help to reduce bloodstream infections in children being treated for AML.

Comparing 123I-MIBG and 18F-MFBG Imaging in Patients With Newly Diagnosed, High Risk Neuroblastoma

This phase II trial evaluates whether an investigational scan (18F-MFBG positron emission tomography \[PET\]/computed tomography \[CT\] or PET/magnetic resonance imaging \[MRI\]) can accurately detect tumors in patients with newly diagnosed, high-risk neuroblastoma as well as standard of care imaging with 123 I-MIBG. 18F-MFBG is a radioactive diagnostic agent that is injected into a vein and taken up by tumor cells. The cells can then be visualized using PET/CT or PET/MRI scans. A PET scan uses radioactive material injected into the blood to show the internal workings of the body. A CT scan uses x-rays and a computer to produce a 3-dimensional image of the body. MRI uses radiofrequency waves and a strong magnetic field rather than x-rays to provide clear and detailed pictures of internal organs and tissues. Combining PET with CT or MRI may help doctors better understand the extent and the exact location of disease. Diagnostic procedures, such as 18F-MFBG PET/CT or PET/MRI, may detect tumors as well as or better than the current standard imaging with 123 I-MIBG in patients with newly diagnosed, high-risk neuroblastoma.

Inotuzumab Ozogamicin and Post-Induction Chemotherapy in Treating Patients With High-Risk B-ALL, Mixed Phenotype Acute Leukemia, and B-LLy

This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy and immunotherapy (chemo-immunotherapy) for patients with High-Risk B-cell Acute Lymphoblastic Leukemia (B-ALL) improves outcomes. Inotuzumab ozogamicin is a monoclonal antibody, which is a type of protein that can bind to certain targets on the surface of cells. Inotuzumab ozogamicin is a monoclonal antibody that is linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells by binding to the CD22 protein on the surface of the cancer cell and delivering calicheamicin inside the cells to kill them. Other drugs used in the chemotherapy regimen, such as cyclophosphamide, cytarabine, dexamethasone, doxorubicin, daunorubicin, methotrexate, leucovorin, mercaptopurine, prednisone, thioguanine, vincristine, and pegaspargase or calaspargase pegol work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Blinatumomab is a specialized type of monoclonal antibody known as a bispecific T-cell engager (BiTE). It works by simultaneously binding to CD19 on cancer cells and CD3 on normal immune cells, bringing them together to destroy leukemia cells. Blinatumomab is a standard part of chemo-immunotherapy treatment for B-ALL. This trial also studies the outcomes of patients with mixed phenotype acute leukemia (MPAL), and B-lymphoblastic lymphoma (B-LLy) when treated with ALL therapy without inotuzumab ozogamicin or blinatumomab. The overall goal of this study is to understand if adding inotuzumab ozogamicin to standard of care chemo-immunotherapy maintains or improves outcomes in High Risk B-cell Acute Lymphoblastic Leukemia (HR B-ALL). The first part of the study includes the first phase of therapy: Induction. This part will collect information on the leukemia, as well as the effects of the initial treatment, to classify patients into post-induction treatment groups. On the second part of this study, patients with HR B-ALL will receive the remainder of the chemotherapy cycles (consolidation, blinatumomab block 1, interim maintenance 1, blinatumomab block 2, delayed intensification, interim maintenance 2, maintenance), with some patients randomized to receive inotuzumab. The patients that receive inotuzumab will not receive part of consolidation or part of delayed intensification. Other aims of this study include evaluating 1) side effects of treatment using patient-reported outcomes and health-related quality of life, 2) the best ways to help patients adhere to oral chemotherapy regimens, 3) the relationship between levels of inotuzumab ozogamicin in the blood and side effects, 4) the impact of chemo-immunotherapy on the immune system and risk of infection, and 5) the impact of social determinants of health on outcomes. Finally, this study will be the first to track the outcomes of subjects with disseminated B-cell Lymphoblastic Leukemia (B-LLy) or Mixed Phenotype Acute Leukemia (MPAL) when treated with B-ALL chemotherapy.

A Study to Compare Standard Chemotherapy to Therapy With CPX-351 and/or Gilteritinib for Patients With Newly Diagnosed AML With or Without FLT3 Mutations

This phase III trial compares standard chemotherapy to therapy with liposome-encapsulated daunorubicin-cytarabine (CPX-351) and/or gilteritinib for patients with newly diagnosed acute myeloid leukemia with or without FLT3 mutations. Drugs used in chemotherapy, such as daunorubicin, cytarabine, and gemtuzumab ozogamicin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. CPX-351 is made up of daunorubicin and cytarabine and is made in a way that makes the drugs stay in the bone marrow longer and could be less likely to cause heart problems than traditional anthracycline drugs, a common class of chemotherapy drug. Some acute myeloid leukemia patients have an abnormality in the structure of a gene called FLT3. Genes are pieces of DNA (molecules that carry instructions for development, functioning, growth and reproduction) inside each cell that tell the cell what to do and when to grow and divide. FLT3 plays an important role in the normal making of blood cells. This gene can have permanent changes that cause it to function abnormally by making cancer cells grow. Gilteritinib may block the abnormal function of the FLT3 gene that makes cancer cells grow. The overall goals of this study are, 1) to compare the effects, good and/or bad, of CPX-351 with daunorubicin and cytarabine on people with newly diagnosed AML to find out which is better, 2) to study the effects, good and/or bad, of adding gilteritinib to AML therapy for patients with high amounts of FLT3/ITD or other FLT3 mutations and 3) to study changes in heart function during and after treatment for AML. Giving CPX-351 and/or gilteritinib with standard chemotherapy may work better in treating patients with acute myeloid leukemia compared to standard chemotherapy alone.

Testing the Addition of Daratumumab to Chemotherapy for Treating Patients With Newly-Diagnosed T-Cell Lymphoblastic Leukemia (T-ALL) and T-Cell Lymphoblastic Lymphoma (T-LL)

This phase II/III trial tests the addition of daratumumab to chemotherapy for treating patients with newly-diagnosed T-ALL and T-LL. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Chemotherapy drugs work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy with daratumumab may kill more cancer cells.

A Study on How to Safely Guide Surgery for Melanoma and Similar Skin Tumors in Children Using Pathology and Genetic Information

This clinical trial compares the effect of using risk-based stratification to guide surgical management to the usual approach in treating cutaneous melanoma, atypical Spitz/Spitzoid tumors or other atypical melanocytic tumors that have not spread to other parts of the body (localized). Melanoma is a cancer that in children is sometimes difficult to tell apart from benign (not harmful) or atypical (uncertain if harmful) skin lesions. Failure to diagnose melanoma can result in inadequate surgical removal and increase the risk of recurrence and metastatic disease (spread from where it first started to other places in the body). In addition, diagnosing a tumor a benign (not cancer) tumor as cancer may lead to unnecessary surgery and treatment. This trial reviews tumor pathology and genetic markers and classifies the tumor as not atypical, atypical but low risk for spread and/or recurrence (coming back after a period of improvement), and atypical and high risk for spread and/or recurrence. The classifications are then used to provide surgical recommendations. Tumors that are not atypical do not receive any surgical treatment. Low-risk recommendations include removing a small layer of normal skin around the tumor. High-risk recommendations include the usual adult melanoma approach of removing a larger layer of normal skin around the tumor with or without a biopsy of the sentinel lymph node (the first lymph node to which tumor cells are likely to spread from a primary tumor). Risk-based guided surgical management may help avoid unnecessary surgery while improving outcomes in younger patients with localized cutaneous melanoma, atypical Spitz/Spitzoid tumors or other atypical melanocytic tumors.

Inotuzumab Ozogamicin in Treating Younger Patients With B-Lymphoblastic Lymphoma or Relapsed or Refractory CD22 Positive B Acute Lymphoblastic Leukemia

This phase II trial studies how well inotuzumab ozogamicin works in treating younger patients with B-lymphoblastic lymphoma or CD22 positive B acute lymphoblastic leukemia that has come back (relapsed) or does not respond to treatment (refractory). Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called ozogamicin. Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers ozogamicin to kill them.

Testing the Addition of an Anti-Cancer Drug, AZD1390, During Radiation Therapy for Newly Diagnosed High Grade Glioma, Diffuse Midline Glioma, or Diffuse Intrinsic Pontine Glioma

This phase I clinical trial studies the side effects and best dose of AZD1390 and to see how well it works when given together with radiation therapy for the treatment of pediatric patients with high grade glioma, diffuse midline glioma or diffuse intrinsic pontine glioma. AZD1390 is in a class of medications called kinase inhibitors. It works by blocking the signals that cause cancer cells to repair deoxyribonucleic acid damage caused by cancer treatments, such as radiation therapy. This may help overcome resistance to therapy seen in these cancers and therefore lead to increased death of cancer cells. Radiation therapy uses high energy x-rays or particles to kill cancer cells and shrink tumors. Giving AZD1390 with radiation may be safe, tolerable, and effective in treating pediatric patients with high grade glioma, diffuse midline glioma or diffuse intrinsic pontine glioma.

Testing a Standardized Approach to Surgery and Chemotherapy for Type I Pleuropulmonary Blastoma or the Addition of an Anti-cancer Drug, Topotecan, to the Usual Treatment for Types II and III Pleuropulmonary Blastoma

This phase III trial tests how well surgery plus chemotherapy compared to surgery alone works in treating patients with type I pleuropulmonary blastoma (PPB), and tests how well surgery plus standard chemotherapy with the addition of topotecan works compared to surgery plus standard chemotherapy alone in treating patients with type II and III PPB. Historically, most children with type I PPB had surgery and approximately 40% of children with type I PPB received chemotherapy following their surgery, usually for 22-42 weeks. There has not been a consistent standard for which children with type I PPB receive chemotherapy after surgery. For patients whose tumor has been removed completely with surgery, observation without chemotherapy may work as well as giving chemotherapy after surgery in preventing a return of the PPB tumor. The standard chemotherapy for patients with types II or III PPB in the United States is four cycles of IVADo (ifosfamide, vincristine, dactinomycin, and doxorubicin) followed by 8 cycles of IVA (ifosfamide, vincristine and dactinomycin). Ifosfamide is in a class of medications called alkylating agents. It works by slowing or stopping the growth of tumor cells in the body. Vincristine is in a class of medications called vinca alkaloids. It works by stopping tumor cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy (antineoplastic antibiotic). It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill tumor cells. It also blocks a certain enzyme needed for cell division and DNA repair. Topotecan is in a class of medications called topoisomerase I inhibitors. It works by interfering with tumor cell DNA which kills them. Giving topotecan in addition to standard IVADo and IVA chemotherapy regimens may shrink the cancer as well as or better than the standard therapy or could decrease the chance the tumor spreads while causing fewer side effects.

Testing the Addition of an Anti-cancer Drug, DT2216, to the Usual Chemotherapy Treatment for Relapsed or Refractory Solid Tumors and Fibrolamellar Carcinoma

This phase I/II trial tests the safety, side effects and best dose of DT2216 in combination with irinotecan and how well it works in treating children, adolescents and young adults with solid tumors and fibrolamellar cancer that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). DT2216 is an anti-apoptotic protein B-cell lymphoma-extra large targeted protein degrader. It may stop the growth of tumor cells by blocking Bcl-xL, a protein needed for tumor cell survival. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and deoxyribonucleic acid repair and may kill tumor cells. Giving DT2216 in combination with irinotecan may be safe, tolerable, and/or effective in treating children, adolescents and young adults with relapsed or refractory solid tumors or fibrolamellar cancer.

Triptorelin for the Prevention of Ovarian Damage in Adolescents and Young Adults With Cancer

This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

A Study Using Risk Factors to Determine Treatment for Children With Favorable Histology Wilms Tumors (FHWT)

This phase III trial studies using risk factors in determining treatment for children with favorable tissue (histology) Wilms tumors (FHWT). Wilms Tumor is the most common type of kidney cancer in children, and FHWT is the most common subtype. Previous large clinical trials have established treatment plans that are likely to cure most children with FHWT, however some children still have their cancer come back (called relapse) and not all survive. Previous research has identified features of FHWT that are associated with higher or lower risks of relapse. The term "risk" refers to the chance of the cancer coming back after treatment. Using results of tumor histology tests, biology tests, and response to therapy may be able to improve treatment for children with FHWT.

A Study of the Drug Letermovir as Prevention of Cytomegalovirus Infection After Stem Cell Transplant in Pediatric Patients

This phase III single arm trial determines whether taking prophylactic letermovir will reduce the likelihood of infection with cytomegalovirus (CMV) in children and adolescents after stem cell transplant compared to estimated rate of infection without prophylaxis. The treatments used to prepare for HCT reduce the body's natural infection-fighting ability and increase the likelihood of an infection with a virus called cytomegalovirus. "Prophylaxis" means to take a drug to prevent a disease or side effect. Letermovir is an antiviral drug that stops cytomegalovirus from multiplying and may prevent cytomegalovirus infection and make the disease less severe.

A Study About How Blood Cell Growth Patterns Relate to Heart Health After Treatment for Hodgkin Lymphoma

This study assesses how blood cell growth patterns (clonal hematopoiesis) relate to heart health or cardiovascular disease (CVD) after treatment in patients with Hodgkin lymphoma. In some patients, cancer treatment at a young age may lead to later complications, including problems with heart health. Checking for blood cell growth patterns called therapy-related clonal hematopoiesis (t-CH) can help predict who might be at risk for heart health problems after Hodgkin lymphoma treatment. If doctors know who may be at greater risk for developing later heart complications, then they can more closely monitor those patients to prevent or detect heart complications early.

A Study of Treatment for Medulloblastoma Using Sodium Thiosulfate to Reduce Hearing Loss

This phase III trial tests two hypotheses in patients with low-risk and average-risk medulloblastoma. Medulloblastoma is a type of cancer that occurs in the back of the brain. The term, risk, refers to the chance of the cancer coming back after treatment. Subjects with low-risk medulloblastoma typically have a lower chance of the cancer coming back than subjects with average-risk medulloblastoma. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effective at treating the cancer, there are still concerns about the side effects of such treatment. Side effects or unintended health conditions that arise due to treatment include learning difficulties, hearing loss or other issues in performing daily activities. Standard therapy for newly diagnosed average-risk or low-risk medulloblastoma includes surgery, radiation therapy, and chemotherapy (including cisplatin). Cisplatin may cause hearing loss as a side effect. In the average-risk medulloblastoma patients, this trial tests whether the addition of sodium thiosulfate (STS) to standard of care chemotherapy and radiation therapy reduces hearing loss. Previous studies with STS have shown that it may help reduce or prevent hearing loss caused by cisplatin. In the low-risk medulloblastoma patients, the study tests whether a less intense therapy (reduced radiation) can provide the same benefits as the more intense therapy. The less intense therapy may cause fewer side effects. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. The overall goals of this study are to see if giving STS along with standard treatment (radiation therapy and chemotherapy) will reduce hearing loss in medulloblastoma patients and to compare the overall outcome of patients with medulloblastoma treated with STS to patients treated without STS on a previous study in order to make sure that survival and recurrence of tumor is not worsened.

Chemotherapy for the Treatment of Patients With Newly Diagnosed Very Low-Risk and Low Risk Fusion Negative Rhabdomyosarcoma

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

Thoracotomy Versus Thoracoscopic Management of Pulmonary Metastases in Patients With Osteosarcoma

This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer. Thoracoscopy is a type of chest surgery where the doctor makes several small incisions and uses a small camera to help with removing the cancer. This trial is being done evaluate the two different surgery methods for patients with osteosarcoma that has spread to the lung to find out which is better.

Tegavivint for the Treatment of Recurrent or Refractory Solid Tumors, Including Lymphomas and Desmoid Tumors

This phase I/II trial evaluates the highest safe dose, side effects, and possible benefits of tegavivint in treating patients with solid tumors that has come back (recurrent) or does not respond to treatment (refractory). Tegavivint interferes with the binding of beta-catenin to TBL1, which may help stop the growth of tumor cells by blocking the signals passed from one molecule to another inside a cell that tell a cell to grow.

A Study of a New Way to Treat Children and Young Adults With a Brain Tumor Called NGGCT

This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patient's response to induction chemotherapy in patients with non-germinomatous germ cell tumors (NGGCT) that have not spread to other parts of the brain or body (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dose chemotherapy followed by conventional RT in patients who did not respond to induction chemotherapy. Chemotherapy drugs, such as carboplatin, etoposide, ifosfamide, and thiotepa, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays or high-energy protons to kill tumor cells and shrink tumors. Studies have shown that patients with newly-diagnosed localized NGGCT, whose disease responds well to chemotherapy before receiving radiation therapy, are more likely to be free of the disease for a longer time than are patients for whom the chemotherapy does not efficiently eliminate or reduce the size of the tumor. The purpose of this study is to see how well the tumors respond to induction chemotherapy to decide what treatment to give next. Some patients will be given RT to the spine and a portion of the brain. Others will be given high dose chemotherapy and a stem cell transplant before RT to the whole brain and spine. Giving treatment based on the response to induction chemotherapy may lower the side effects of radiation in some patients and adjust the therapy to a more efficient one for other patients with localized NGGCT.
