Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Dosage	NCT01760226 ↗	Dose Adjusted EPOCH-R, to Treat Mature B Cell Malignancies	Completed	National Cancer Institute (NCI)	Early Phase 1	2013-01-01	The subject is invited to take part in this research study because s/he has been diagnosed with Diffuse Large B-Cell Lymphoma (DLBCL), Primary Mediastinal B-cell Lymphoma (PMBCL), or Post-transplant Lymphoproliferative Disorder (PTLD). In an attempt to improve cure rates while reducing harmful effects from drugs, oncologists are developing new treatment protocols. One such protocol, entitled dose-adjusted EPOCH-R, utilizes two major new strategies. First, the treatment approach utilizes continuous infusion of chemotherapy over four days, instead of being administered over minutes or hours. Secondly, the doses of some medications involved are increased or decreased based on how the drugs affect the subject's ability to produce blood cells, which is used as a measure of how rapidly the body is processing drugs. Using this approach in adults, researchers have shown improved cure rates in these cancers. Additionally, the harmful effects experienced by patients has been mild, with mucositis, severe infections, and tumor lysis syndrome occurring rarely. However, this new dosing method has never been used in children, and the effectiveness and side effects of this new method are unknown in children. The purpose of this study is to look at the safety of dose-adjusted EPOCH-R in the treatment of children with mature B-cell cancers, and to see if we can maintain cure rates (as has been shown in adults). This study represents the first trial of dose-adjusted EPOCH-R in children.

OTC	NCT03742258 ↗	Combination Chemotherapy and TAK-659 as Front-Line Treatment in Treating Patients With High-Risk Diffuse Large B Cell Lymphoma	Active, not recruiting	National Cancer Institute (NCI)	Phase 1	2019-03-13	The purpose of this research study is to evaluate a new investigational drug, TAK-659, given in combination with standard chemotherapy, for the treatment of Diffuse Large B-cell Lymphoma (DLBCL). ?Investigational? means that TAK-659 has not been approved by the United States Food and Drug Administration (FDA) for use as a prescription or over-the-counter medication to treat a certain condition. The primary purpose of this study is to find the appropriate and safe dose of the study drug to be used in combination with standard chemotherapy for the treatment of your disease and to determine how well the drug works in treating the disease. Other objectives include measuring the amount of the study drug in the body at different times after taking the study drug. Participation in the study is expected to last for up to 3 years after receiving the last dose of the study drug. Patients will receive the study treatment for up to 18 weeks, as long as they are benefitting.
