Pediatric Cancer

The goal of this clinical trial is to learn if sonrotoclax (BGB-11417) is safe and may help treat children and adolescents with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) that has come back after treatment or has not responded to treatment. The study will also learn how the body processes sonrotoclax when it is given with other medicines. The main questions it aims to answer are: * Is sonrotoclax safe and well tolerated when given with other anti-cancer medicines? * How does the body absorb, process, and remove sonrotoclax? * Does treatment with sonrotoclax, in combination with other medicines, help reduce or eliminate leukemia? Researchers will give sonrotoclax together with other anti-cancer medicines to participants with relapsed or refractory AML or ALL. Participants will: * Take sonrotoclax in combination with other anti-cancer medicines * Have regular clinic visits for physical exams, blood tests, heart monitoring, and other safety assessments. * Provide blood samples to measure how the body processes sonrotoclax. * Have tests to evaluate how their leukemia responds to treatment. * Continue treatment as long as it is helping and side effects remain manageable, according to the study plan.

This mixed-methods pilot study will examine the effect of music therapy on oral mucositis pain in pediatric oncology patients. Oral mucositis, characterized by painful ulcerative lesions in the mouth, is a common side effect of high-dose chemotherapy and hematopoietic stem cell or bone marrow transplantation. Despite its high prevalence and impact on quality of life, effective pain management strategies for pediatric oral mucositis remain limited and often rely heavily on medications that may cause significant side effects or provide insufficient relief. Music therapy may offer a promising non-pharmacologic adjunct for reducing pain, yet no studies to date have specifically evaluated its use for oral mucositis pain in pediatric patients.

Background: * Cancer has an enormous impact on the psychological and social well-being of the family unit. The life-threatening connotations of cancer single out the ill child from his peer/family group as one who is different, and often unable to maintain a normal lifestyle. Physical sequelae of cancer and its treatment accentuate the differences between these children and their normal peers/siblings. * It is important that children with cancer be prepared to function outside of protected situations and begin to develop skills of separation and independence. For healthy children, some of these latter skills are acquired by a camping experience. Such an experience for the patient with cancer is frequently precluded by their dependence on medical facilities and the physical limitations of their activities. * The goal of this study will be to assess the short and long term benefits of the "normalized" camping experience, provided in conjunction with Special Love, Inc., on the patients and staff. In particular, we will seek to determine whether such a comprehensive experience is capable of influencing the attitudes and life experiences of patients and staff in a positive manner. Objectives: -To evaluate the impact of an enriched normalized camping experience on the quality of life of the pediatric cancer patient. In particular, attempts will be made to measure the manner in which this experience influences the child's sense of well-being and self-esteem as well as his or her relationship with parents, family, and peers. Eligibility: * Children 7-17 years of age who are currently being treated for cancer or are up to 3 years post therapy OR Young adults with cancer (YACers) 18-25 years of age who are acting as counselors at Camp Fantastic * All children/young adults will be selected for camp after careful screening by a multidisciplinary committee consisting of medical and program directors. * At the discretion of the multidisciplinary committee consisting of medical and program directors, special exceptions may be made for children with extenuating circumstances. Design: * Assessment of benefit may include interviews with children and families before, during and following camp. Observational data on the child's performance at camp will be noted. * Medical and nursing personnel will consist of staff from the Pediatric Branch at the NCI, other units within the NIH, and participating institutions. * Special Love members, the Program Director at the 4-H Center camp (site of the camp) and Pediatric Branch staff at the NCI will coordinate the camp program, taking into account the medical needs of each camper. * Every attempt will be made to provide a full agenda of age appropriate activities for the patients. * The length of the camping experience for children with cancer will be for 7 days beginning on a Sunday and extending through the following Saturday morning. Patients will be transported to the camp from the NIH Clinical Center and the Virginia hospitals by bus.

The primary purpose of this study is to determine the pediatric maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D), and to evaluate the safety and tolerability of zanzalintinib.

This study will evaluate BCB-276, an investigational B7-H3-targeted Chimeric Antigen Receptor (CAR) T cell therapy, in children and young adults with diffuse intrinsic pontine glioma (DIPG). DIPG is a rare and aggressive brain tumor with limited treatment options. CAR T cell therapy uses a patient's own immune cells that are changed in a laboratory to recognize and attack cancer cells. The purpose of this study is to determine whether BCB-276, when given after completion of standard radiation therapy, is safe and can improve survival for patients with DIPG. To participate, individuals must be between 1 and 26 years of age when they join the study, have a diagnosis of DIPG, and enroll for treatment within 6 weeks of completing initial radiation therapy. Participants must not have received prior anti-cancer therapy beyond radiation with or without temozolomide prior to joining this study. BCB-276 is administered intraventricularly (into the fluid around the brain), which requires placement of a catheter for treatment. BCB-276 is given every 2 weeks at a research center over a period of several months (approximately 7-8 months). Participation includes travel to a study site, procedures to support treatment administration, sample collection, and ongoing monitoring for safety and effectiveness, with follow-up visits lasting up to about 2 years.

This study is being conducted to determine how best to educate caregivers about cancer and its treatment. When caregivers are well-informed, they are more confident in supporting their child through treatment, which can improve treatment adherence.

Papillary thyroid cancer (PTC) is the most common form of differentiated thyroid cancer (DTC). The traditional first line treatment for patients with advanced DTC after surgical resection is radioactive iodine (RAI) therapy. However, less than a quarter of patients with lung metastases will achieve a complete response to RAI therapy, and this therapy carries the risk of pulmonary fibrosis and an increasingly recognized risk of secondary malignancies.

It involves collecting safety and efficacy data, under the actual conditions of use of off label and compassionate use medicines in children and adolescents approved in humans before 2007, using a validated tool (Ennov EDC) and relying on the network recognised pediatric hemato-oncology centers in Belgium and responsible for the organization of Pediatric National tumor boards which discuss each case of relapse in order to define the best therapeutic options.

Pharmacogenomic (PGx) testing involves analyzing variants of genes associated with drug metabolism, transport and medication targets. PGx testing uses an individual's genetic factors, such as single nucleotide polymorphisms (SNPs), to personalize therapy or dose a selection of medications. PGx testing has traditionally been used to test single genes, but there are now platforms allowing a panel of genes to be tested at once. To date there has not been a comprehensive screening of pediatric oncology patients to determine the prevalence of genetic variants that may affect anticancer therapy and supportive care medications. This study would allow us to summarize the frequency of clinically relevant gene-drug interactions and actionable genetic polymorphisms in pediatric oncology patients.

The purpose of this study is to see if there are physical and emotional benefits to participating in a structured exercise regimen for those who are ages 2-25, are newly diagnosed with a blood or solid tumor cancer, and are currently undergoing or will begin cancer treatment.

Pediatric cancer survivors have increased infection-related morbidity and mortality. This study will evaluate immune dysfunction following cancer directed systemic therapy completion, with attention to clinical relevance and infection rate in this population compared to healthy siblings, when applicable. The investigators will also restart vaccinations at earlier time points than previously studied, at 3 months post therapy, and will assess whether boosters or revaccination schedules are superior for regaining immunity against potentially serious infections in survivors.

The goal of this research study is to learn if the FoodiiS-Kids intervention is useful to parents and guardians of pediatric cancer survivors.

It is critical to provide accessible evidence-based psychosocial support to parents and caregivers of children with cancer (PCCC) in order to mitigate individual and family-level psychosocial risks. This effectiveness trial evaluates an eHealth intervention for English- and Spanish-speaking (PCCC) with study endpoints focused on decreasing negative psychosocial sequelae (acute distress, posttraumatic stress, and anxiety) and improving coping abilities (coping self-efficacy, cognitive coping strategies). The long-term goal of this research program is to sustain and disseminate an effective, scalable, high-reach, and cost-effective intervention to provide crucial support to PCCC across the pediatric cancer trajectory.

This proof-of-concept platform trial is designed to cover the targeting of several survival pathways in oncogenesis that are currently not adequately employed for pediatric patients in Europe (Geoerger 2017; Geoerger 2019). The aims of the trial are: 1. To determine the recommended phase II dose (RP2D) of a specific anticancer agent and/or a relevant combination in a pediatric population, to document its tolerability and 2. To explore first signals of activity in a molecularly enriched study population.

In this first-in-human, muticenter, non-randomized, open-label, standard 3+3 dose escalation Phase I study encompasses 5 parts (Part 1-5). The purpose of this FIH study is to evaluate the safety and tolerability profile of CBA-1205.

Influenza infection occurring during oncologic treatment or following hematopoietic cell transplantation (HCT) is associated with increased risk of morbidity in the form of lower respiratory tract infection (LRTI) and mortality relative to otherwise healthy patients. The study participants have been diagnosed with a hematological malignancy and are eligible to receive the current seasonal influenza (Flu) vaccine. Primary Objective * To determine the feasibility of opening a longitudinal prospective study of IIV immunogenicity in pediatric leukemia patients. * To describe the immunogenicity, as measured by the development of cell- and/or antibody-mediated influenza specific responses 3 to 5 weeks following vaccination, in a cohort of pediatric leukemia patients. Secondary Objectives * To describe whether an immune response, as measured by development of cell- and/or antibody-mediated influenza specific responses, is detectable 1-2 weeks following vaccination in a cohort of pediatric leukemia patients. * To describe the durability of immunogenicity by measuring cell - and antibody- mediated influenza specific responses at 6 months and 1 year following vaccination in a cohort of pediatric leukemia patients. Exploratory Objectives * To estimate the clinical effectiveness of influenza vaccine in this cohort by monitoring for the development of clinical diagnosis of influenza in the cohort of enrolled pediatric oncology patients. * To correlate results of immune cell frequency in blood, as measured by complete blood count with differential, with development of an immune response to IIV.

Cancer is a leading cause of illness and death among children, adolescents, and young adults(CAYAs), especially in low- and middle-income countries(LMICs), where access to timely diagnosis and treatment is often limited. As a result, patients in these settings may experience higher rates of treatment complications, interruptions, and poorer outcomes compared with those in high-income countries (HICs). This is a prospective, multicenter observational study that will follow children, adolescents, and young adults(CAYAs) with cancer who are receiving routine care at participating hospitals in low - and middle - income countries(LMICs). The study does not involve experimental treatments or changes to standard medical care. Information will be collected from medical records and from questionnaires that address access to care and social factors affecting treatment. By describing treatment outcomes and the challenges patients and families face during cancer care, this study aims to provide data that can help inform future efforts to improve access to care and cancer outcomes in resource-limited settings.

The objective of this study is to utilize all donated pediatric tumor tissues and cells obtained from autopsy to prospectively develop novel patient derived orthotopic xenograft (PDOX) mouse models as well as in vitro cell culture model systems for pediatric cancers, and also provide tissue samples to other researchers and organizations (eg, CBTN, DIPG Registry, COG).

The purpose of this study is to develop a mechanism for utilizing the comprehensive clinical database of childhood cancer survivors at Childrens Hospital Los Angeles (CHLA) for research purposes. Using clinical information obtained from follow-up visits of childhood cancer survivors, the database will focus on interventions to improve health status and health-related quality of life in childhood cancer survivors. This study allows for establishment and analyses of a research database for LIFE survivors by the investigators listed herein. Over the last three decades, there has been marked improvement in survival following childhood cancer, with 5-year survival rates now approaching 80%. However, the use of cancer therapy at an early age can result in complications that may not be apparent until years later as the child matures. These resulting complications, called late effects, are principally related to the specific therapy employed and the age of the child at the time the therapy was administered. Late effects may affect virtually every body system and substantially impair quality of life. As many as two-thirds of childhood cancer survivors develop at least one late effect as a result of treatment, and approximately one-third have a late effect classified as severe or life threatening.

COMPRENDO (ChildhOod Malignancy Peer Research NavigatiOn) is a multi-site randomized clinical trial (RCT) that uses a Hybrid Type 1 design, to test the effects of a clinical intervention on patient-level outcomes, while exploring multilevel implementation factors that can inform real-world setting implementation. This study will test the impact of COMPRENDO, a peer-navigation intervention, vs. usual care on accrual to childhood cancer therapeutic clinical trials and parental informed consent outcomes. COMPRENDO will be delivered by trained peer navigators in 4 visits. A mixed methods (surveys, individual interviews) implementation evaluation will examine implementation factors that can inform the use of peer navigation in clinical practice, integrating data from clinicians, navigators, administrators, and parents pre and post the RCT.

For a young patient, the conditions of proton therapy treatment can be stressful. Adjusting the environment can be a source of avoiding this physical and psychological discomfort impacting the quality of treatment. A fixed, long, uncomfortable position is the main cause of stress, already present due to the cancerous therapeutic course. It extends the positioning time. For the patient and the optimization of his treatment, solutions must be sought. Relaxation in virtual reality is efficient, simple and non-medicinal and could reduce stress in children and allow irradiation in very good conditions. We will assess the effectiveness of the virtual reality session using objective (placement time, helmet tolerance) and subjective (perceived anxiety via a dedicated questionnaire) criteria. This is the first pediatric virtual reality study, supported by the French Group of Pediatric Radiotherapists, to reduce anxiety in radiotherapy. Multiple benefits from this pilot study are expected, such as improved reception conditions, treatment parameters and better acceptance of proton therapy sessions.

This is a phase I/II study to evaluate the safety of combining intravenous (IV) atezolizumab and bevacizumab every three weeks, with daily oral cyclophosphamide and pharmacokinetic (PK)-guided sorafenib in children and adolescent and young adults (AYA) with relapsed or refractory solid malignancies (Part 1), and then evaluate the response rate of this combination in children, AYA with relapsed or refractory fibrolamellar carcinoma (FLC) and other rare solid malignancies (Part 2). Primary Objectives Part 1 * To establish the safety associated with the administration of the combination of cyclophosphamide, PK-guided sorafenib, bevacizumab and atezolizumab in children and AYA with relapsed or refractory solid tumors * To determine if sorafenib systemic exposure can be successfully targeted to an AUC between 20 and 55 hr·µg/mL by Day 21 of cycle 1 in 60% of evaluable patients, when given in combination with cyclophosphamide, bevacizumab, and atezolizumab in children and AYA with relapsed or refractory solid tumors Part 2 * To evaluate the response rate (CR+PR) of the combination of cyclophosphamide, PK-guided sorafenib, bevacizumab and atezolizumab in children and AYA with relapsed or refractory FLC following two cycles of therapy * To determine if the use of PK-guided sorafenib dosing to maintain a systemic exposure between 20 and 55 reduces the interpatient pharmacokinetic variability of sorafenib and the incidence of sorafenib- induced skin toxicities in children and AYA with relapsed or refractory FLC and other rare solid tumors Parts 1 \& 2 * To determine if the combination of cyclophosphamide, PK-guided sorafenib and atezolizumab will result in increased intratumoral T-cell infiltration of CD8+C45RO+ cells between baseline and following two courses of therapy in pediatric children and AYA with relapsed or refractory solid tumors following two cycles of therapy * To characterize the pharmacokinetics of atezolizumab in combination with cyclophosphamide, PK-guided sorafenib and bevacizumab in children and AYA with relapsed or refractory solid tumors * To assess the feasibility of performing contrast enhanced ultrasound and explore the correlation between quantitative CEUS parameters and clinical response. Secondary Objectives Part 1 • To describe the response rate (CR+PR) of the combination of cyclophosphamide, PK-guided sorafenib, bevacizumab and atezolizumab in children and AYA with relapsed or refractory solid tumors following two cycles of therapy Part 2 • To describe the response rate (CR+PR) of the combination of cyclophosphamide, PK-guided sorafenib, bevacizumab and atezolizumab in children and AYA with relapsed or refractory FLC, HCC, desmoplastic small round cell tumor, malignant rhabdoid tumor, and other rare solid tumors following two cycles of therapy Parts 1\&2 * To describe the number of children with liver tumors, initially judged unresectable at diagnosis, that can have their primary tumor resected after treatment with oral cyclophosphamide and sorafenib with intravenous bevacizumab and atezolizumab * To describe changes in immune cells in the peripheral blood at periodic times before and after treatment with this combination chemoimmunotherapy * To describe the PFS, EFS, and OS in patients treated with the combination of cyclophosphamide, PK-guided sorafenib, bevacizumab, and atezolizumab in patients with relapsed or refractory FLC, DSRCT, MRT, HCC and other rare solid tumors

The goal of this clinical trial is to evaluate whether stopping antibiotic treatment early is safe in paediatric patients with cancer who develop high-risk febrile neutropenia but show good clinical evolution and low biomarker levels 48-72 hours after the episode. The main questions it aims to answer are: Is early discontinuation of antibiotics as safe as the standard strategy in terms of preventing invasive bacterial infections (such as sepsis, microbiologically documented infection, ICU admission, or death)? Does this strategy reduce the number of days on antibiotics without increasing infection-related complications? Researchers will compare early antibiotic discontinuation with the standard care strategy to see whether the early-stop approach provides similar safety while reducing antibiotic exposure. Participants will: Receive standard initial antibiotic therapy for febrile neutropenia. Undergo clinical and biomarker evaluations (including CRP and PCT). Be randomly assigned to: Experimental group: early discontinuation of antibiotics, or Control group: continuation of the standard antibiotic strategy. Be followed for 28 days after randomisation to monitor safety outcomes and treatment effects.

Childhood cancer requires prolonged and intensive treatment, resulting in significant biopsychosocial challenges for affected children and their families. During and following treatment, children frequently experience impairments in fine and gross motor skills, reduced physical capacity, emotional difficulties, and decreased participation in daily activities. Within the framework of the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY), these impairments in body structure and function may negatively influence activity, participation, and overall quality of life. Dance therapy is a holistic rehabilitation approach that integrates rhythm, structured movement, and emotional expression to enhance motor performance, body awareness, and psychosocial well-being. Emerging evidence suggests that dance-based interventions may contribute to improved pain management, psychological resilience, and emotional health in pediatric oncology populations. However, access to structured physical activity programs remains limited due to treatment-related fatigue, infection risk, travel burden, time constraints, and financial costs. Telerehabilitation may overcome these barriers by delivering therapy remotely, thereby improving accessibility, reducing logistical constraints, and ensuring continuity of care. The aim of this randomized controlled trial is to evaluate the effects of an 8-week telerehabilitation-based dance therapy program (twice weekly, 35-40 minutes per session) on fine and gross motor skills, health-related quality of life, participation in home, school, and community settings, and motivation in children undergoing or recently completing cancer treatment.

The goal of this clinical trial is to learn if the VIDEO-PEDS intervention works to improve Goals of Care communication between clinicians and parents of children with cancer. The main questions it aims to answer are: Does the intervention improve Goals of Care documentation? Does it improve patient outcomes (including less invasive preferences for resuscitation and interventions, less hospital utilization, and more palliative care and hospice use)? Does it improve parent outcomes (including health satisfaction and feeling heard and understood per survey scores)?
