CLINICAL TRIALS PROFILE FOR AMNESTEEM

All Clinical Trials for AMNESTEEM

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00004188 ↗	Combination Chemotherapy and Peripheral Stem Cell Transplantation in Treating Patients With Neuroblastoma	Completed	National Cancer Institute (NCI)	Phase 3	2001-02-01	RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: This randomized phase III trial is studying peripheral stem cell transplantation with treated peripheral stem cells following combination chemotherapy to see how well it works compared to peripheral stem cell transplantation with untreated peripheral stem cells following combination chemotherapy in treating patients with neuroblastoma.
NCT00004188 ↗	Combination Chemotherapy and Peripheral Stem Cell Transplantation in Treating Patients With Neuroblastoma	Completed	Children's Oncology Group	Phase 3	2001-02-01	RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: This randomized phase III trial is studying peripheral stem cell transplantation with treated peripheral stem cells following combination chemotherapy to see how well it works compared to peripheral stem cell transplantation with untreated peripheral stem cells following combination chemotherapy in treating patients with neuroblastoma.
NCT00005576 ↗	Monoclonal Antibody Therapy With Sargramostim and Interleukin-2 in Treating Children With Neuroblastoma	Completed	National Cancer Institute (NCI)	Phase 1	2001-01-01	Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood. Interleukin-2 may stimulate a person's white blood cells to kill cancer cells. Combining monoclonal antibody therapy with sargramostim or interleukin-2 may kill more tumor cells. Phase I trial to study the effectiveness of monoclonal antibody therapy given with sargramostim and interleukin-2 in treating children with neuroblastoma who have just completed bone marrow or peripheral stem cell transplantation
NCT00025038 ↗	Combination Chemotherapy Followed By Donor Bone Marrow or Umbilical Cord Blood Transplant in Treating Children With Newly Diagnosed Juvenile Myelomonocytic Leukemia	Completed	National Cancer Institute (NCI)	Phase 2	2001-06-01	Giving chemotherapy drugs, such as R115777, isotretinoin, cytarabine, and fludarabine, before a donor bone marrow transplant or an umbilical cord transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. This phase II trial is studying how well giving combination chemotherapy together with donor bone marrow or umbilical cord blood transplant works in treating children with newly diagnosed juvenile myelomonocytic leukemia
NCT00026312 ↗	Isotretinoin With or Without Dinutuximab, Aldesleukin, and Sargramostim Following Stem Cell Transplant in Treating Patients With Neuroblastoma	Active, not recruiting	National Cancer Institute (NCI)	Phase 3	2001-10-18	This partially randomized phase III trial studies isotretinoin with dinutuximab, aldesleukin, and sargramostim to see how well it works compared to isotretinoin alone following stem cell transplant in treating patients with neuroblastoma. Drugs used in chemotherapy, such as isotretinoin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as dinutuximab, may block tumor growth in different ways by targeting certain cells. Aldesleukin and sargramostim may stimulate a person's white blood cells to kill cancer cells. It is not yet known if chemotherapy is more effective with or without dinutuximab, aldesleukin, and sargramostim following stem cell transplant in treating neuroblastoma.
NCT00098891 ↗	MS-275 and Isotretinoin in Treating Patients With Metastatic or Advanced Solid Tumors or Lymphomas	Completed	National Cancer Institute (NCI)	Phase 1	2004-10-01	Phase I trial to study the effectiveness of combining MS-275 with isotretinoin in treating patients who have metastatic or advanced solid tumors or lymphomas. MS-275 may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Isotretinoin may help cancer cells develop into normal cells. MS-275 may increase the effectiveness of isotretinoin by making cancer cells more sensitive to the drug. MS-275 and isotretinoin may also stop the growth of solid tumors or lymphomas by stopping blood flow to the cancer. Combining MS-275 with isotretinoin may kill more cancer cells
NCT00217412 ↗	Vorinostat With or Without Isotretinoin in Treating Young Patients With Recurrent or Refractory Solid Tumors, Lymphoma, or Leukemia	Completed	National Cancer Institute (NCI)	Phase 1	2005-08-01	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.
