This phase III trial studies how well response and biology-based risk factor-guided therapy works in treating younger patients with non-high risk neuroblastoma. Sometimes a tumor may not need treatment until it progresses. In this case, observation may be sufficient. Measuring biomarkers in tumor cells may help plan when effective treatment is necessary and what the best treatment is. Response and biology-based risk factor-guided therapy may be effective in treating patients with non-high risk neuroblastoma and may help to avoid some of the risks and side effects related to standard treatment.

This phase II trial studies how well naive T-cell depletion works in preventing chronic graft-versus-host disease in children and young adults with blood cancers undergoing donor stem cell transplant. Sometimes the transplanted white blood cells from a donor attack the body's normal tissues (called graft versus host disease). Removing a particular type of T cell (naive T cells) from the donor cells before the transplant may stop this from happening.

This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

This 2-part study will evaluate the safety and efficacy of pembrolizumab (MK-3475) compared to placebo in participants with surgically resected high-risk Stage II melanoma. Participants in Part 1 will receive either pembrolizumab or placebo in a double-blind design every 3 weeks (Q3W) for up to 17 cycles/\~1 year (each cycle = 21 days). Participants who complete the initial treatment of 17 cycles of pembrolizumab in Part 1 and experience disease recurrence may be eligible for re-challenge with pembrolizumab at the same dose and schedule of 200 mg Q3W (21-day cycles) for up to 35 cycles (up to \~2 years) in Part 2 in an open label design. Participants who complete the initial treatment of placebo and experience disease recurrence may be eligible to switch over to pembrolizumab 200 mg Q3W (21-day cycles) for up to 35 cycles (up to \~2 years) in Part 2 in an open label design. The primary hypothesis of this study is that pembrolizumab increases recurrence-free survival (RFS) compared to placebo.

Per protocol, response/ progression or adverse events (AEs) during re-challenge/switch-over in Part 2 will not be counted towards the RFS outcome measure or safety outcome measures respectively.

This is a single-arm open-label phase Ib/II clinical study assessing the efficacy of concurrent high dose ascorbate in combination with radiotherapy in patients with locally advanced, resectable, high grade sarcomas.

The investigators want to study if lower doses of chemotherapy will help babies with SCID to achieve good immunity with less short and long-term risks of complications after transplantation. This trial identifies babies with types of immune deficiencies that are most likely to succeed with this approach and offers them transplant early in life before they get severe infections or later if their infections are under control. It includes only patients receiving unrelated or mismatched related donor transplants.

The study will test if patients receiving transplant using either a low dose busulfan or a medium dose busulfan will have immune recovery of both T and B cells, measured by the ability to respond to immunizations after transplant. The exact regimen depends on the subtype of SCID the patient has. Donors used for transplant must be unrelated or half-matched related (haploidentical) donors, and peripheral blood stem cells must be used. To minimize the chance of graft-versus-host disease (GVHD), the stem cells will have most, but not all, of the T cells removed, using a newer, experimental approach of a well-established technology. Once the stem cell transplant is completed, patients will be followed for 3 years. Approximately 9-18 months after the transplant, vaccinations will be administered, and a blood test measuring whether your child's body has responded to the vaccine will be collected.

This phase III trial studies iobenguane I-131 or lorlatinib and standard therapy in treating younger patients with newly-diagnosed high-risk neuroblastoma or ganglioneuroblastoma. Radioactive drugs, such as iobenguane I-131, may carry radiation directly to tumor cells and not harm normal cells. Lorlatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving iobenguane I-131 or lorlatinib and standard therapy may work better compared to lorlatinib and standard therapy alone in treating younger patients with neuroblastoma or ganglioneuroblastoma.

This randomized phase III trial studies how well combination chemotherapy (vincristine sulfate, dactinomycin, cyclophosphamide alternated with vincristine sulfate and irinotecan hydrochloride or vinorelbine) works compared to combination chemotherapy plus temsirolimus in treating patients with rhabdomyosarcoma (cancer that forms in the soft tissues, such as muscle), and has an intermediate chance of coming back after treatment (intermediate risk). Drugs used 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. Combination chemotherapy and temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether chemotherapy plus temsirolimus is more effective than chemotherapy alone in treating patients with intermediate-risk rhabdomyosarcoma.

The purpose of this Phase 1b study is to assess the safety and maximum tolerated dose (MTD) of Decitabine in combination with Gemcitabine among previously treated patients diagnosed with advanced pancreatic adenocarcinoma or sarcoma (soft tissue and bone).
