Clinical Trials

Intensive Neoadjuvant Chemotherapy in Treating Young Patients Undergoing Surgical Resection for High-Risk Hepatoblastoma Not Recruiting
More
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy drugs before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well neoadjuvant chemotherapy works in treating young patients who are undergoing surgical resection for high-risk hepatoblastoma.

Lenalidomide in Treating Young Patients With Relapsed or Refractory Solid Tumors or Myelodysplastic Syndromes Not Recruiting
More
This phase I trial is studying the side effects and best dose of lenalidomide in treating young patients with relapsed or refractory solid tumors or myelodysplastic syndromes. Lenalidomide may stop the growth of solid tumors or myelodysplastic syndromes by blocking blood flow to the cancer. It may also stimulate the immune system in different ways and stop cancer cells from growing.

A Study of Venetoclax in Combination With Navitoclax and Chemotherapy in Subjects With Relapsed/Refractory Acute Lymphoblastic Leukemia or Relapsed/Refractory Lymphoblastic Lymphoma Not Recruiting
More
This dose-escalating study is to determine the safety, pharmacokinetics, and preliminary efficacy of venetoclax in combination with navitoclax and chemotherapy in adult and pediatric participants with relapsed/refractory acute lymphoblastic leukemia (ALL) or relapsed/refractory lymphoblastic lymphoma. A safety expansion cohort of approximately 20 patients may be enrolled in addition to the 50 participants in dose-escalation cohort.

Vorinostat With or Without Isotretinoin in Treating Young Patients With Recurrent or Refractory Solid Tumors, Lymphoma, or Leukemia Not Recruiting
More
This phase I trial is studying the side effects and best dose of vorinostat when given together with isotretinoin in treating young patients with recurrent or refractory solid tumors, lymphoma, or leukemia. Drugs used in chemotherapy, such as vorinostat, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Isotretinoin may cause cancer cells to look more like normal cells, and to grow and spread more slowly. Giving vorinostat together with isotretinoin may be an effective treatment for cancer.

Phase I Dose Escalation Study of CD19/CD22 Chimeric Antigen Receptor (CAR) T Cells in Children and Young Adults With Recurrent or Refractory B Cell Malignancies Recruiting
More
This phase I trial studies the best dose and side effects of CD19/CD22 chimeric antigen receptor (CAR) T cells when given together with chemotherapy, and to see how well they work in treating children or young adults with CD19 positive B acute lymphoblastic leukemia that has come back or does not respond to treatment. A CAR is a genetically-engineered receptor made so that immune cells (T cells) can attack cancer cells by recognizing and responding to the CD19/CD22 proteins. These proteins are commonly found on B acute lymphoblastic leukemia. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving CD19/CD22-CAR T cells and chemotherapy may work better in treating children or young adults with B acute lymphoblastic leukemia.

A Study of Clofarabine in Combination With Etoposide and Cyclophosphamide in Children With Acute Leukemias. Not Recruiting
More
Clofarabine (injection) is approved by the Food and Drug Administration (FDA) for the treatment of pediatric patients 1 to 21 years old with relapsed or refractory acute lymphoblastic leukemia (ALL) who have had at least 2 prior treatment regimens. This use is based on the induction of complete responses. Randomized trials demonstrating increased survival or other clinical benefit have not been conducted. The purpose of the phase 1 portion of this study was to determine if clofarabine added to a combination of etoposide and cyclophosphamide is safe in children with relapsed or refractory acute lymphoblastic leukemia (ALL) or acute myelogenous leukemia (AML). The purpose of the phase 2 portion of the study was to measure the effectiveness of the combination therapy in children with ALL.

RATIONALE: Drugs used in chemotherapy, such as valproic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Valproic acid may also stop the growth of solid tumors or CNS tumors by blocking blood flow to the tumor. PURPOSE: This phase I trial is studying the side effects and best dose of valproic acid in treating patients with recurrent or refractory solid tumors or CNS tumors.

Temozolomide, Vincristine, and Irinotecan in Treating Young Patients With Refractory Solid Tumors Not Recruiting
More
RATIONALE: Drugs used in chemotherapy, such as temozolomide, vincristine, and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of irinotecan when given together with temozolomide and vincristine in treating young patients with refractory solid tumors.

The purpose of this study is to assess the feasibility and efficacy of a novel form of therapy-haploidentical NK cell transplantation-in patients with standard-risk AML. In addition, we will investigate the efficacy of clofarabine + cytarabine (Clo/AraC) in newly diagnosed patients with AML and attempt to optimize outcome through the use of MRD-adapted therapy and further improvements in supportive care.

The Phase II trial is designed to study the effectiveness of BCX-1777 in treating patients who have recurrent or refractory advanced T-cell leukemia. Patients will receive an infusion of BCX-1777 on days 1-5. Treatment may be repeated every week for up to six courses. Patients are not required to be hospitalized for the administration of BCX-1777. Some patients may continue to receive an infusion of BCX-1777 twice a week for 6 weeks.

Combination Chemotherapy Plus PSC-833 in Treating Children With Refractory or Relapsed Acute Leukemia Not Recruiting
More
Phase I trial to study the effectiveness of PSC-833 plus etoposide and mitoxantrone in treating children who have refractory or relapsed acute leukemia. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Some cancers become resistant to chemotherapy drugs. Combining PSC-833 with chemotherapy may reduce resistance to the drug and allow more cancer cells to be killed.
