Filter by:The purpose of this study is to determine the maximum tolerated dose and evaluate the safety of the administration of donor lymphocytes depleted of alloreactive T-cells following a stem cell transplant from a related, haploidentical donor, in patients with severe hematologic malignancies.
Haemopoietic stem cell transplantation (HSCT) has become a major life-saving treatment for many haematological conditions, mostly malignancies. However, there are lots of potential complications that hinder the long-term success of HSCT, in which bronchiolitis obliterans syndrome (BOS) is one of such serious complications. Basically, BOS represents a form of graft-versus-host immunological damage of small airways (bronchioles), leading to progressive narrowing of small airways and thus obstructive lung function abnormalities. With progressive loss of lung function in BOS, patients after HSCT can be complicated by intractable respiratory failure that results in mortality. Up until now, there is still no reliable way to accurately predict or detect BOS early to allow pharmacological interventions. Therefore there is intense interest in the search for biomarkers that can help to predict the occurrence of BOS after HSCT. Apart from biomarkers (e.g., cytokines) in blood, there has been recent development in the sampling of airway lining fluid by a non-invasive method, i.e., collection of exhaled breath condensate (EBC). In airway diseases such as asthma or chronic obstructive pulmonary disease, EBC has been found to have various cytokines which can serve as potential biomarkers of disease activity. Since BOS is largely a small airway disease, it becomes logical to investigate the profile of biomarkers in EBC as predictors for BOS after HSCT. Therefore this study has been designed to look into the role of biomarkers in blood and EBC in early detection of BOS after HSCT.
The goal of this clinical research study is to compare the effectiveness of receiving a combination of ondansetron and aprepitant to receiving ondansetron alone in helping to prevent nausea and/or vomiting in patients with Acute myeloid leukemia (AML) or high-risk (HR) Myelodysplastic syndromes (MDS) who are receiving cytarabine. The safety of this drug combination will also be studied.
This phase II clinical trial studies how well treosulfan and fludarabine phosphate with or without low dose radiation before donor stem cell transplantation works in treating patients with nonmalignant (noncancerous) diseases. Hematopoietic cell transplantation has been shown to be curative for many patients with nonmalignant (noncancerous) diseases such as primary immunodeficiency disorders, bone marrow failure syndromes, hemoglobinopathies, and inborn errors of metabolism (metabolic disorders). Powerful chemotherapy drugs and/or radiation are often used to condition the patient before infusion of the new healthy donor cells. The purpose of the conditioning therapy is to destroy the patient's abnormal bone marrow which doesn't work properly in order to make way for the new healthy donor cells which functions normally. Although effective in curing the patient's disease, many hematopoietic cell transplantation regimens use intensive chemotherapy and/or radiation which can be quite toxic, have significant side effects, and can potentially be life-threatening. Investigators are investigating whether a new conditioning regimen that uses less intensive drugs (treosulfan and fludarabine phosphate) with or without low dose radiation results in new blood-forming cells (engraftment) of the new donor cells without increased toxicities in patients with nonmalignant (noncancerous) diseases.
The scientific aim of this study is to evaluate patient comprehension of the 77 newly developed items as well as the extent to which the items correspond to the concepts of interest for each patient reported outcome (PRO). A secondary aim of this study is to evaluate the usability of the technology interface for collecting the PRO data of the PRO-CTCAE system once it has been built to accommodate the learning garnered during the cognitive interviews.
To determine the time to and rate of hematologic engraftment following unrelated umbilical cord blood transplantation in adults with one or two cord blood units using total body irradiation and fludarabine as the transplant conditioning regimen and cyclosporine/MMF as graft-versus-host disease prophylaxis.
The purpose of this study is to determine whether treatment with Bismuth can reduce the toxicity of chemotherapy and radiotherapy in patients with malignant diseases of the blood.
The purpose of this study is to determine whether the histone deacetylase inhibitor CHR-2845 is tolerated in patients with haematological diseases and lymphoid malignancies.
The goal of this clinical research study is to learn if cyclophosphamide given after busulfan and fludarabine can help to prevent graft versus host disease (GVHD - a condition in which transplanted tissue attacks the body into which it is transplanted) in patients receiving a stem cell transplant. The safety of this drug combination will also be studied.
Understanding how often the bleeding events occur in the subjects who voluntarily decide to switch from prophylaxis to on-demand and in those subjects who remain on prophylaxis. Also look into the consequences of switching treatment in QoL (quality of life), development of target joints, activity level and reasons that might influence the desire to switch.
