Active clinical trials for "Histiocytosis, Langerhans-Cell"

This is a single-arm study to evaluate the efficacy and safety of CD207 targeted CAR-T cell therapy in relapsed and refractory langerhans cell histiocytosis.

The long-term outcomes of adult patients with pulmonary Langerhans cell histiocytosis (PLCH), particularly survival, is largely unknown. This is the first prospective study in the field evaluating the long-term outcomes of PLCH patients. This french countrywide registry-based study included a large cohort of PLCH patients followed for a sufficiently long period to address risk factors of long-term outcomes of PLCH patients.

This study gathers health information for the Project: Every Child for younger patients with cancer. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.

The long-term goal is to define the mechanisms of pathogenesis underlying Langerhans cell histiocytosis (LCH). The overall objectives of the current study are to characterize the role of SMAD6 inherited genetic variation on LCH susceptibility and identify germline genomic regions associated with LCH somatic mutations. Building from preliminary data, the central hypotheses are: (1) causal genetic variants in SMAD6 underlie susceptibility to LCH, and (2) differences in LCH-related somatic activating mutations by race/ethnicity are related to Amerindian (i.e., Native American) genetic ancestry. The Central hypothesis will be tested by pursuing the specific aims.

The hypothesis is to determine if a preparative regimen of busulfan, cyclophosphamide, and antithymocyte globulin (ATG) plus allogeneic stem cell transplantation will be effective in the treatment of immune deficiencies and histiocytic disorders.

RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of indium In 111 pentetreotide in treating patients who have refractory cancer.

RATIONALE: Giving a monoclonal antibody, such as alemtuzumab, and chemotherapy drugs, such as fludarabine and melphalan, before a donor stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells and helps stop the growth of abnormal 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving alemtuzumab together with fludarabine and melphalan followed by a donor stem cell transplant works in treating young patients with resistant Langerhans cell histiocytosis.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of Langerhans cell histiocytosis, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may be an effective treatment for Langerhans cell histiocytosis. PURPOSE: This randomized clinical trial is studying combination chemotherapy to see how well it works in treating young patients with Langerhans cell histiocytosis.

This phase I trial studies the side effects and the best dose of sunitinib malate in treating human immunodeficiency virus (HIV)-positive patients with cancer receiving antiretroviral therapy. Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

This phase II trial studies how well an umbilical cord blood transplant with added sugar works with chemotherapy and radiation therapy in treating patients with leukemia or lymphoma. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer 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. The umbilical cord blood cells will be grown ("expanded") on a special layer of cells collected from the bone marrow of healthy volunteers in a laboratory. A type of sugar will also be added to the cells in the laboratory that may help the transplant to "take" faster.
