This study is for participants that have been diagnosed with Medulloblastoma. The purpose of this study is to test the effectiveness of using an investigational agent called DFMO for Medulloblastoma. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). This study will look at the ability of this study drug to either keep participants tumor in remission or if they have active tumor, for their tumor to respond to the treatment and will also look at the safety and tolerability of DFMO. After this first day participants will be seen in clinic once every 30 days for the first 6 months of the study, after that they will be seen once every 90 days for the remainder of the study. These visits will last about 2 hours.

This study is for participants with tumors from pediatric cancers and genomic/molecular testing was done as part of standard of care treatment. This is an observational study; therefore, only information about the disease and medical treatment will be collected and participants will not receive any treatments or additional medications. The sponsor, Beat Childhood Cancer, will collect and store personal health information and molecular/genomic test results, tissue samples, and bodily fluids (examples: additional tube(s) of blood, urine, bone marrow or cerebral spinal fluid) that are left over after testing or treatment is completed in a data registry and a specimen bank, and make these available for future research. Database personnel will continue to collect and store participant information from future visits, as long as they do not withdraw from participation in this study.

The purpose of this research study is to develop a better understanding of the cause and natural history of vascular anomalies and related syndromes. This study is being done in order to develop a better understanding of the cause of vascular anomalies in order to to improve care for people who are affected by these anomalies and related syndromes.

This study is being done at the University of Wisconsin-Madison (UW-Madison) and other sites in North America and Europe. A total of about 1000 people will participate in this study. About 20 – 30 people will take part in the study here at the Medical University of South Carolina.

This study is for patients who have been diagnosed with relapsed or refractory CD22+ B-Acute Lymphoblastic Leukemia (B-ALL). The overall goal of this study is to find out what effect, good and/or bad, the drug inotuzumab ozogamicin has on children and young adults with relapsed or refractory B-ALL. Participants can expect to be on this study for up 2 months and followed for up to 5 years.

In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.

This study is for patients that have newly diagnosed High-Risk B-ALL, Risk-Adapted Post-Induction therapy for High-Risk B-ALL, Mixed Phenotype Acute Leukemia, and Disseminated B-LLy. The treatment involves medicine called chemotherapy, which fights cancer. Some patients may also need radiation therapy depending on whether the cancer has spread to the brain and spinal fluid, or the testes for males. The investigational drug on this study is inotuzumab ozogamicin. Participants can expect to be on this study for a little over 2 years and followed for up to 10 years.

This study is for patients that have been diagnosed with Newly Diagnosed Diffuse Anaplastic Wilms Tumors (DAWT) and Relapsed Favorable Histology Wilms Tumors (FHWT). The treatment involves cancer fighting medicine called chemotherapy plus radiation therapy and/or surgery. Participants can expect to be on this study for up to 10 months and be followed by the treatment team for up to 5 years.

This study is for patients that have been diagnosed with Acute Myelogenous Leukemia (AML). This study will compare standard chemotherapy using daunorubicin, cytarabine and gemtuzumab ozogamicin (GO) to chemotherapy using an experimental drug called CPX-351. CPX-351 is made up of daunorubicin and cytarabine. CPX-351 is made in a way that makes the drugs stay in the bone marrow longer and may be more effective. CPX-351 has been shown to be well-tolerated and effective against leukemia in adults and children. Participants can expect to receive treatment on this study for 6 months and followed for up to 10 years.

The Advanced Cardiac Therapies Improving Outcomes Network (ACTION) is a distributed network-based learning health system (LHS) of care centers, clinicians, researchers and industry representatives partnering with patients who have heart failure and their caregivers with the ultimate aim of achieving health, longevity and quality of life equivalent to the general population. See https://www.actionlearningnetwork.org for more information. The initial focus will be to apply structured quality improvement methods, advanced information technology systems, and sharing of best practices to track and continuously improve health-related outcomes for children with heart failure requiring advanced therapies. In the future, we plan to collaborate with other established registries and learning network (i.e. UNOS, PHTS and Cardiac Networks United) to create an integrated network that improves care throughout all phases of a patient's illness including chronic heart failure, acute decompensated heart failure, ventricular assist device support and transplant.

This study is for patients with recurrent/progressive medulloblastoma, which is a type of childhood brain tumor. Participants in this study will receive intravenous (IV, into the veins) bevacizumab and intrathecal (into the spinal fluid) or intraventricular (into the fluid surrounding the brain) etoposide and cytarabine in combination with five oral (taken by mouth) chemotherapy drugs as a possible treatment for recurrent/progressive medulloblastoma. Total study duration is about 1 year and depending on how well a participant tolerates the medications and the response of the disease, the patient may continue the treatment after the first year.
