Human subjects are being recruited for the proposed study to participate in usability testing for a virtual reality technology tool to be refined for assessment and prevention of risky sexual and substance use behaviors. Specifically, 15 adolescents, 15 young men, and 15 front line health care providers will participate in qualitative interviews and focus groups. Targeted enrollment is based on estimates from the existing clinical population treated by the local clinics from which participants will be recruited and the candidate's experience conducting clinical studies at these sites.

Phase 3 sample will include 20 adolescents, 20 young men, and 10 frontline health care workers. They will complete assessments/interviews, a brief emotion regulation skills training, and a simulation using a refined virtual reality tool.

This study is for participants that have been diagnosed with a high-risk neuroblastoma that cannot be treated or did not improve with existing therapies, or the cancer came back after treatment with existing therapies. This study involves investigational drugs called 64Cu-SARTATE and 67Cu-SARTATE. The investigational drugs will be given as an IV injection. The study is divided into 2 parts: The Dose Escalation Phase and the Cohort Expansion Phase. The phase that participants will enroll to will depend on when they enter the study. The age range for participants is from 12 months to 25 years. Participants can expect to be in this study for approximately 14 months. Then followed by remote or virtual visits every 6 months for up to 36 months (3 years) after the initial dose of study therapy drug 67Cu-SARTATE.

The purpose of this study is to test the effectiveness of a comprehensive treatment for African-American adolescents with obesity and their overweight or obese caregiver (e.g., parent). Families who decide to participate in this study will be randomly assigned to one of two intervention groups: the FIT Families group or the Home-Based Family Support (HBFS) group. This means participants have a 50/50 chance (like flipping a coin) of being in either group. Participants randomized to FIT Families will have sessions with a community health worker (CHW) in the home or community once or twice weekly based on the family's preference for the first three months, and weekly for the second three months. Some of the sessions might occur virtually (online) if needed. Participants randomized to HBFS will receive six months of weekly family counseling in their home or community with a community health worker (CHW). Some of these sessions might occur virtually (online) if needed. Participants in both groups will receive education and support for healthier lifestyles.
The study will last 18 months. During the 18-month study period, youth and caregivers will wear a FitBit activity tracker during the six months of the intervention and then for 2 weeks at the fourth assessment, complete study assessments, have their height, weight, and blood pressure measured, and provide finger prick blood samples to be tested for blood sugar and cholesterol levels.
Potential benefits to caregivers and youth who participate in the study include: positive changes in healthy lifestyle behaviors and weight loss, decrease in health risks associated with obesity, and improved family relations, though these cannot be guaranteed.

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 is an observational study, which means that only information is collected on treatment, examinations or diagnostic tests which are a part of the routine standard of care. The participant is being asked to volunteer because they have been diagnosed with locally advanced or metastatic TRK fusion cancer treated with larotrectinib. The purpose of this study is to learn more about the safety profile and the effectiveness of VITRAKVI® under routine practice conditions.
Participants will be followed for a minimum of 5 years from the time they agree to participate in the study.

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 Epstein-Barr Virus associated Post-Transplant Lymphoproliferative Disorder (EBV-PTLD). The investigational drug in this study is tabelecleucel. Tabelecleucel is a product containing special immune allogeneic cells, called EBV-Cytotoxic T Lymphocytes (EBV-CTLs), that are made in the laboratory starting with cells from a healthy person who is immune to EBV. The purpose of this study is to test how well tabelecleucel works to treat EBV-PTLD following SOT in patients who have not responded to rituximab or rituximab plus chemotherapy treatment and to see what side effects happen. Your participation will help us to understand more about tabelecleucel. In the first 12-month period, participants will be asked to come to the clinic for an estimated 11 to 19 study visits and a minimum of 2 scans, depending on the number of cycles of treatment they are given. After treatment is done, participants will enter into the follow-up phase, and will continue to come into the clinic for scheduled check-ups for up to 24 months after the first dose of tabelecleucel was given. Participant information on the status of their disease and any new treatment will be collected for up to an additional 3 years. Participants can expect to be in this study for up to five years total.

This study is for patients that have been diagnosed with multisystem Langerhans cell histiocytosis (LCH). The purpose of this study is to find out if prolonging the treatment and adding a drug called 6-mercaptopurine will be beneficial. Other goals include fining out if these changes will result in fewer patients having relapse of their LCH, and fewer patients having long term disease related problems. Participants can expect to be in this study for up to 24 months and will be followed on this study fir at least 5 years.

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.
