The treatment (chemotherapy and transplant procedures) is considered standard clinical care that are usually given to the patients with this disease. The research aspect of this study is to collect data on the patients who are being treated on this plan. Patients will be followed throughout the course of their clinical care and for three years after their transplant.

This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a type of disease that occurs when the body makes too many immature Langerhans cells (a type of white blood cell). When these cells build up, they can form tumors in certain tissues and organs including bones, skin, lungs and pituitary gland and can damage them. This tumor is more common in children and young adults. DAY101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Using DAY101 may be effective in treating patients with relapsed or refractory Langerhans cell histiocytosis.

This will be a Phase II, two-arm, nonrandomized, non-comparative, open-label study in participants ≥ 1 year of age with iobenguane avid, recurrent or progressive high-risk neuroblastoma. Participants not eligible for vorinostat treatment may receive 131I-MIBG as monotherapy.

This is a treatment protocol for an unrelated umbilical cord blood transplant (UCBT) using a myeloablative preparative regimen for the treatment of hematological diseases, including, but not limited to acute leukemias. There is no research element except the collection of routine clinical data.

This phase II trial studies how stopping tyrosine kinase inhibitors will affect treatment-free remission in patients with chronic myeloid leukemia in chronic phase. When the level of disease is very low, it's called molecular remission. TKIs are a type of medication that help keep this level low. However, after being in molecular remission for a specific amount of time, it may not be necessary to take tyrosine kinase inhibitors. It is not yet known whether stopping tyrosine kinase inhibitors will help patients with chronic myeloid leukemia in chronic phase continue or re-achieve molecular remission.

This trial is an open label, randomized, stratified 2-arm Australian-led multicenter phase 3 clinical trial undertaken in two stages. Participants (age >= 11 years and <= 45 years) with intermediate and poor-risk metastatic germ cell tumors will be randomized into either a “standard BEP” group or “accelerated BEP” group. Participants will be assigned to the two treatment arms in a 1:1 ratio and evaluated weekly, and then for 5 years after completing the study to assess the long-term effects of the chemotherapy. Bleomycin, Etoposide, Cisplatin (BEP) administered 3-weekly x 4 remains standard 1st line chemotherapy for intermediate- and poor-risk metastatic germ cell tumours (GCTs). BEP is accelerated by cycling Cisplatin and etoposide 2-weekly instead of 3-weekly. The aim of this study is to determine if accelerated BEP is superior to standard BEP as first-line chemotherapy for intermediate and poor risk metastatic GCTs.

This trial will evaluate other treatment options for high-risk NMIBC patients who were unresponsive to Bacillus Calmette Guerin (BCG therapy). We are studying two different drugs in combination with pembrolizumab. Participants will receive up to 35 doses of the trial drug and have tumor assessments for about 2 years. This will be followed by treatment tumor assessment for another 3 years for a total trial duration of 5 years.

The purpose of this study is to learn the effects, good or bad, of several possible study treatments for EndoCA that are selected based on genetic markers that can be found in these tumors.

This is a prospective, case-control, multi-center, observational nonsignificant risk study. The study includes two phases: Lung EpiCheck assay development and clinical validation. Samples collected under this protocol will support both phases. The study includes two subject groups: a Cases Series and a Screening Series.

The investigational therapy in this study is referred to as Restorative Microbiota Therapy (RMT). It is prepared by extracting healthy bacteria from the stool of healthy human donors and making it into capsules taken by mouth. The donor stool samples are rigorously tested for harmful bacteria and viruses before processing. There is scientific evidence to suggest that RMT might make immunotherapy more effective. The primary goal of the study is to test if RMT makes durvalumab + tremelimumab treatment with chemotherapy more effective to control lung cancer.

In this study, the researchers are collecting blood samples to learn more about laronidase treatment in children that receive a hematopoietic cell transplantation. The laronidase dose regimens used after a hematopoietic cell transplantation may differ from those administered before. This study will establish the basis for determining if there is a need to adjust laronidase dosing regimens after receiving a hematopoietic cell transplantation.

This research is being done to determine whether the investigational drug tabelecleucel (allogeneic Epstein-Barr virus-specific cytotoxic T lymphocytes [EBV-CTLs]) can help people with EBV-associated diseases.

CGD disorders are a group of diseases that cause the immune system to function abnormally, leading to infections, autoimmunity and/or inflammation that can begin early in life. CGD is usually caused by changes in certain genes in DNA. Researchers are trying to learn what types of medical problems patients with CGD have and how these respond to treatment, including bone marrow transplantation and gene therapy. Researchers also want to learn which genes cause CGD and how specific gene abnormalities lead to medical problems.

The primary objective for this observational study is to collect general and medical data from children, adolescents, and young adults who had pediatric onset rheumatic disease. This data will be used to evaluate the long-term safety and efficacy of therapeutic agents used to treat these diseases. This information will allow investigators to accurately report and follow changes in current medication use patterns and compare these to proposed standards and current treatment recommendations. The use of a single registry will allow for more analysis of the different therapeutic agents by allowing them to be compared to each other.

The purpose of this study is to better understand how tobacco and nicotine products affect our bodies. In this observational study smokers, vapers, smokeless tobacco users, nicotine replacement product users, non-users, and ex-users will be asked to provide biological samples. We will look for biological “markers” (biomarkers), or chemical changes in the body, that occur due to tobacco or nicotine exposure. Collected samples will be used for the development of biomarkers of toxicant exposure and for assessing exposure between the different groups. The intent is to eventually use these biomarkers to improve detection, prevention, and treatment strategies for tobacco-related diseases. This study will allow us to test currently used biomarkers, and to establish a biorepository (sample bank) to identify and develop new biomarkers associated with tobacco exposure and cessation. The type of samples and amount collected will depend on the specific biomarker(s) being developed or tested. Potential samples include saliva, cheek (buccal) & oral cells, blood, urine, hair, and/or nail clippings.
