Active clinical trials for "Hematologic Diseases"

To determine the therapeutic effects of anti-thymocyte globulin (ATG) in patients with aplastic anemia and related bone marrow failure diseases.

To determine whether hydroxyurea prevents the onset of chronic end organ damage in young children with sickle cell anemia.

To evaluate if HLA-mismatched, unrelated-donor umbilical cord blood stem and progenitor cell units (UCBU) offered a clinically acceptable alternative to matched unrelated-donor allogeneic bone marrow for transplantation with 180-day disease free survival as the endpoint. HLA typing was performed using DNA-base high resolution methods to determine HLA alleles. Patients with "true" HLA 3/6 and 4/6 matches were evaluated. In addition, a separate study in adults addressed the problem of limited cell dose and engraftment failure. The study was not planned as a randomized comparative clinical trial. Instead, it is a phase II/III efficacy study.

Immunotherapy with Chimeric Antigen Receptor (CAR) T Cells, T cells whose receptor has been genetically modified, is based on improving the immune response against the tumor. This approach is promising for patients with hematologic malignancies refractory to chemotherapy. Despite impressive results, too many patients are relapsing. The reasons for the relapse, after the injection of CAR T cells, need to be explored. In this context of newly introduced therapeutics, it is essential to better understand the factors associated with the response to treatment with CAR T Cells, especially the characteristics of the tumor and its microenvironment. The objective of this study is to understand the role of tumor biology, and its microenvironment, in the response to CAR-T Cells therapy in patients with hematologic malignancies

The purpose of this study is to evaluate whether the use of direct rapid antibiotic susceptibility test (dRAST), in addition to the current standard antibiotic susceptibility test, can increase the proportion of patients with hematologic disease who received appropriate antibiotics in early period of bacteremia.

The goal of this clinical research study is to learn if dexamethasone can help reduce shortness of breath in cancer patients. Researchers also want to learn if it can help to improve lung function and quality of life. In this study, dexamethasone will be compared to a placebo. Dexamethasone is commonly used for treatment of nausea, tiredness, and pain. It may help patients with shortness of breath. A placebo is not a drug. It looks like the study drug but is not designed to treat any disease or illness. It is designed to be compared with a study drug to learn if the study drug has any real effect.

The study team will compare hospital length of stay (LOS) and attributable length of stay (ALOS, the LOS attributable to CRI), in a randomized, un-blinded prospective trial utilizing short-dwell ethanol-lock therapy (ELT) (4 hours to 24 hour dwell times per day, repeated for up to 72 hours) placed within 24 - 36 hours of admission(Group 1, Preemptive ELT) versus ELT placed at the time of first positive blood culture report (Group 2, Rescue ELT (Standard of Care ). ELT will be given in both groups, in combination with systemic antibiotics, for the treatment of CRI (suspected or proven) of the blood in children with central catheters. Participants will be enrolled from patients with hematologic/oncologic disorders and bone marrow or hematopoetic stem cell transplants (BMT) admitted for care to Children's Hospital of Michigan (CHM), a tertiary care pediatric hospital in Detroit, Michigan. ALOS will be defined as the number of hospital days between first symptoms of Catheter-related infection (CRI) (or date of admission for those admitted with symptoms) and first negative blood culture. Study Hypothesis: The main hypothesis is that the short-dwell ethanol-lock therapy, defined above, placed within 24 - 36 hours of symptoms/admission (Arm 1) versus ELT placement at the time of first positive blood culture report (Arm 2), with concomitant systemic antibiotics, for the treatment of CRI (suspected or proven) of the blood in children with central catheters in the H/O/BMT population will have shorter hospital length of stay (LOS) and attributable LOS (ALOS) and therefore lower hospital costs.

Rituximab is frequently used in adult and pediatric cancers, blood disorders, lymphoma (a cancerous growth made up of lymphoid tissue), graft-versus-host-disease (complication that can occur after a stem cell or bone marrow transplant), diseases of the immune system (the cells and substances that protect the body from infection) and rheumatologic conditions. Rituximab works by decreasing or temporarily eliminating a specific type of white blood cell, the B-lymphocyte. Overall, rituximab is generally well tolerated. The likelihood of an infusion-related reaction, or symptoms such as fever, chills, hives, low blood pressure or swelling, is very low, but highest during a patient's first infusion of rituximab and decreases with each additional dose. Adults commonly receive rituximab at a faster rate if they have done well with the first infusion, this study will help determine if the same approach is well tolerated in children. In this study, the investigators are testing a new method of administering rituximab which may reduce the time it takes to receive the medication. The initial ordered amount of rituximab will not change from the current standard of care (meaning what is usually done by doctors, and would likely be done if you were not on this study). The period of time over which rituximab is given is what is being studied.

The study evaluates the safety and potential early signals of efficacy of allogeneic Thrombosomes in bleeding thrombocytopenic patients

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.
