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.

Babies that are born extremely prematurely are at higher risk of developing chronic (long term) lung disease (CLD) and other complications (problems). The purpose of this study is to test the safety and effectiveness of an investigational drug called mecasermin rinfabate (rhIGF-1/rhIGTBP-3) or OHB-607. The researchers want to find out if OHB-607 can help reduce the risk of chronic lung disease in babies born prematurely and if it can help reduce the risk of other complications.

This study is for patients that have been diagnosed metastatic germ cell tumors. This study will compare the standard chemotherapy regimen with an accelerated chemotherapy regimen using the same drugs to see if the accelerated chemotherapy regimen is beneficial but not more toxic than the standard chemotherapy regimen. The accelerated chemotherapy is experimental. Participants can expect to be on study for about 3 months and continue to be followed for up to 5 years.

This study is for patients that have been diagnosed with Leukemia or Lymphoma. and have been treated on one of the following studies: Pediatric Oncology Group (POG) 9404, 9425, 9426, or Dana Farber Cancer Institute (DFCI) ALL Consortium 95-01. The purpose of this study is to look at the heart function of patients selected by change to get DRZ compared to the heart function of patients selected by chance not to get DRZ. In this study, they will also look at gender, age at cancer diagnosis, current age, dose of chemotherapy, and if chest radiation influences the risk of early heard damage. Participants in this clinical trial are expected to come to one clinic visit.

This study is for patients that have been diagnosed with Germ Cell Tumors. The purpose of this study is to evaluate whether a strategy of complete surgical resection followed by surveillance can maintain an overall survival rate of at least 95.7% at two years for pediatric, adolescent and adult patients (ages 0- 50 years) with Stage I (low risk) malignant germ cell tumors, and at least 98% for patients with ovarian pure immature teratoma. The drugs used in this study are carboplatin and cisplatin. Participants will be followed for up to 10 years.
