NCT ID: NCT03213652 Recruiting - Clinical trials for Malignant Solid Neoplasm

Ensartinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With ALK or ROS1 Genomic Alterations (A Pediatric MATCH Treatment Trial)

Start date: April 17, 2018
Phase: Phase 2
Study type: Interventional

This phase II Pediatric MATCH trial studies how well ensartinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with ALK or ROS1 genomic alterations that have come back (recurrent) or does not respond to treatment (refractory) and may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Ensartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

NCT ID: NCT03210714 Active, not recruiting - Clinical trials for Advanced Malignant Solid Neoplasm

Erdafitinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With FGFR Mutations (A Pediatric MATCH Treatment Trial)

Start date: June 5, 2018
Phase: Phase 2
Study type: Interventional

This phase II Pediatric MATCH trial studies how well erdafitinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with FGFR mutations that have spread to other places in the body and have come back or do not respond to treatment. Erdafitinib may stop the growth of cancer cells with FGFR mutations by blocking some of the enzymes needed for cell growth.

NCT ID: NCT03155620 Recruiting - Malignant Glioma Clinical Trials

Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphomas, or Histiocytic Disorders (The Pediatric MATCH Screening Trial)

Start date: July 31, 2017
Phase: Phase 2
Study type: Interventional

This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

NCT ID: NCT03127709 Active, not recruiting - Histiocytosis Clinical Trials

A Study of Memory, Thinking, and Brain Imaging in Adults With Histiocytosis

Start date: April 7, 2017
Phase:
Study type: Observational

The purpose of this study is to try to understand how histopcytosis can cause symptoms or problems in the brain. The tests being done in the study will look at memory and thinking as well as brain function via MRI scan.

NCT ID: NCT03096782 Completed - Clinical trials for Acute Myeloid Leukemia

Umbilical Cord Blood Transplant With Added Sugar and Chemotherapy and Radiation Therapy in Treating Patients With Leukemia or Lymphoma

Start date: October 13, 2017
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT03093727 Recruiting - Clinical trials for Langerhans Cell Histiocytoses

Characterization of Pulmonary Langerhans Cell Histiocytosis

Start date: September 27, 2013
Phase:
Study type: Observational [Patient Registry]

Very recent studies indicate that a high percentage of HCL, about 50%, have mutations in the B-RAF oncogene. The development of ultrasensitive methodologies capable of identifying these mutations in bronchoalveolar lavage will represent a significant advance in the diagnosis and treatment of these patients. An undetermined percentage of HCL does not present mutations in B-RAF. Consequently, the deep genetic analysis, through the use of techniques of massive sequencing, can favor the identification of new alterations that contribute to the development of the disease. We hypothesized that patients with HCL may present a different inflammatory state to healthy subjects or smokers, allowing us to identify new biomarkers.

NCT ID: NCT03052101 Completed - Clinical trials for Pulmonary Langerhans Cell Histiocytosis

Assessment of Safety of Air Travel in Patients With Pulmonary Langerhans Cell Histiocytosis

Start date: June 2016
Phase:
Study type: Observational

The aim of this study is to conduct survey-based assessments for the safety of air travel in patients with pulmonary Langerhans cell histiocytosis (PLCH). The study will enroll patients through the clinic network at Rare Lung Disease Consortium (RLDC) and through the Histiocytosis Association website. Patients will have access to the questionnaire via REDCap (an online data management system) and each patient will be provided with a link to complete the survey. The investigators plan on enrolling approximately 200 patients with PLCH for the purpose of this study. Secondary aims of this study include further characterization of the clinical aspects of disease and to establish a contact registry for these patients, in order to facilitate future studies.

NCT ID: NCT02670707 Recruiting - Clinical trials for Langerhans Cell Histiocytosis

Vinblastine/Prednisone Versus Single Therapy With Cytarabine for Langerhans Cell Histiocytosis (LCH)

Start date: March 7, 2016
Phase: Phase 3
Study type: Interventional

Langerhans Cell Histiocytosis (LCH) is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the BRAF gene. These changes may make the LCH cells grow and multiply quickly. This causes LCH cells to build up in certain parts of the body, where they can damage tissue or form lesions. For most patients with LCH, standard-of-care vinblastine/prednisone are used as front-line therapy while cytarabine therapy has been used as therapy for patients who develop recurrence. No alternate treatment strategy has been developed for frontline therapy in LCH. The purpose of this research study is to compare previously used vinblastine/prednisone to single therapy with cytarabine for LCH. We will evaluate the utility of an imaging study called a positron emission tomography (PET) scan to more accurately assess areas of LCH involvement not otherwise seen in other imaging studies as well as response to therapy. We also want to identify if genetic and other biomarkers (special proteins in patient's blood and in patient's cancer) relate to the response of patients LCH to study treatment.

NCT ID: NCT02668120 Completed - Clinical trials for Chronic Histiocytosis

Search Elevated Serum Alkaline Phosphatase as a Marker of Prenatal Intervillositis Chronic Histiocytic

IHC
Start date: April 16, 2016
Phase:
Study type: Observational

Background : Chronic histiocytic intervillositis is a rare placental disease linked with poor perinatal outcome. In a recent study, a major antenatal increased alkaline phosphatase was suspected in patients affected by chronic histiocytic intervillositis. This increase may correspond to the release of alkaline phosphatase by the syncytiotrophoblaste prejudiced in this pathology. Aim : To confirm the association between high levels of alkaline phosphatase and the occurrence of chronic histiocytic intervillositis.

NCT ID: NCT02665546 Completed - Clinical trials for Langerhans Cell Histiocytosis

Evaluation of Exercise Capacity and Exercise Limitation in Patients With Pulmonary Langerhans Cell Histiocytosis

Start date: March 2016
Phase:
Study type: Observational

Pulmonary Langerhans Histiocytosis Cells (PLCH) is characterized by infiltration of Langerhans cells and formation of loose granulomas with lymphocytic infiltrate and formation of nodular and cystic lesions on chest CT, and is often associated with smoking. Functionally, there may be obstructive and / or restrictive defect, with reduced carbon monoxide diffusing capacity. Dyspnea and lower exercise tolerance are common in PLCH, but exercise capacity in this disease is poorly understood and has not been compared to controls. Besides, the mechanisms involved in limiting exercise are poorly understood and cover multiple factors such as change in gas exchange, pulmonary hypertension (PH), dynamic hyperinflation, physical deconditioning and left heart failure. The involvement of pulmonary circulation in PLCH has unknown prevalence, but contributes to the symptoms. In the PH classification, PLCH belongs to the group 5, of multifactorial etiology. The definition of the presence and contribution of dyspnea mechanisms in different severities of PLCH is important to understanding the disease and individualization of treatment. The objective of the study is to evaluate the exercise capacity of patients with HCLP, and determinate mechanisms of dyspnea and lower exercise tolerance beyond its impact on quality of life.
