Active clinical trials for "Leukemia"

Background: Bone marrow stem cells, which are found in the bone marrow and blood stream, can be collected and transplanted to treat a variety of types of cancer in a process known as hematopoietic stem cell transplantation (HSCT). When stem cells are taken from one person, most commonly a sibling or a family member, and then given to another person, this is referred to as allogeneic HSCT. Allogeneic HSCT has proven to be an especially effective treatment for patients with some types of cancers of the blood (leukemia) and certain solid tumors. The transplanted stem cells travel to the patient's bone marrow and begin producing normal blood cells, and also attack patients cancer cells. Because allogenic HSCT does not always prevent the cancer from returning, researchers are interested in determining whether another type of immune cell taken from the stem cell donors white blood cells, called a "natural killer" (NK) cell, can be given in addition to the HSCT to help fight the tumor. In the laboratory, NK cells have been shown to kill tumor cells, but it is not yet know if this will occur when given to patients after HSCT. Objectives: To determine the safety, effectiveness, and immune system response of giving NK white blood cells to individuals who have received allogeneic HSCT. To identify possible side effects from the treatment. Eligibility: Donors: Stem cell donors whose blood matches one of the recipients on six out of six human leukocyte antigen (HLA) (blood immune marker) types. The donor may not be the identical twin of a recipient. Recipients: Individuals between 4 and 35 years of age who have been diagnosed with pediatric solid tumors that have not responded to standard treatment, or individuals between 4 and 18 years of age who have been diagnosed with leukemia that has not responded to standard treatment. Other eligibility requirements which include a physical exam and blood laboratory evaluation are included to make sure it is safe for both the donor to donate and the recipient to undergo the transplant procedure. Design: Donors and recipients will be screened with a full medical history and physical examination, and will provide blood and urine samples; recipients will have tumor imaging studies and other tests as required by the researchers. Donors: Participants will receive filgrastim injections (to stimulate the bone marrow) for 1 week to make stem cells travel from bone marrow to blood. Participants will provide stem cells and NK cells through apheresis. Recipients: Participants will have three cycles of chemotherapy to treat the underlying cancer and weaken the immune system so that it will accept the donor cells. Participants will then receive preparative chemotherapy for the transplant and two days after the last dose of chemotherapy, participants will have allogenic HSCT using the donated stem cells. Participants will receive an infusion of NK cells on days 7 and 35 after the HSCT. - Participants will remain in the hospital for monitoring after the HSCT and NK cell treatments, and will be followed closely as outpatients for the first 6 months after the transplant and then less frequently for at least 5 years.

In relapsed or refractory AML allogeneic HCT is considered to be the only treatment by which long-term disease-free survival can be achieved. Despite this favorable prospect, even in younger patients with relapsed AML only about 40% of the patients reach allogeneic HCT. A number of factors contribute to this low rate of transplantation, among them moderate activity of the salvage regimens and accumulating toxicities which prevent from transplantation; Prospective clinical trials in this indication usually focus either on the rate of CR achieved after a defined number of cycles of salvage therapy or on transplantation modalities. The consequent integration of salvage therapy into a transplant strategy accounting for the time-dependent process of donor search has not been studied so far. The objective of this study is to evaluate the safety and efficacy of clofarabine salvage therapy prior to allogeneic HCT.

Adult patients with chronic lymphocytic leukaemia who experience a relapse after at least two prior treatment regimens may be enrolled in this trial. The trial will examine whether monotherapy with BI 836826 is safe and tolerable at escalating dose levels.

The aim of this study is to demonstrate the safety and the efficacy of a combination of 2 treatments shown to have some efficacy in Chronic Phase Chronic Myelogenous Leukemia (CP CML) separately, but that have never been combined to date, and this combination is expected to substantially increase the molecular response rates.

Any time the words "you," "your," "I," or "me" appear, it is meant to apply to the potential participant. The goal of this clinical research study is to learn if intensive chemotherapy (hyper-CVAD therapy) given in combination with liposomal vincristine (Marqibo), in addition to rituximab for patients who are CD20 positive and/or imatinib, dasatinib, or ruxolitinib for patients with the Philadelphia (Ph) chromosome, can help to control ALL or lymphoblastic lymphoma. The safety of this treatment will also be studied. CD20 is a protein "marker" that is found in leukemia or lymphoma cells. This is an investigational study. Liposomal vincristine is FDA approved for the treatment of patients with CLL who have relapsed at least 2 times. All of the other study drugs used in this study are FDA approved and commercially available. The combination of liposomal vincristine with the other study drugs is also being used in research only. Up to 65 patients will take part in this study. All will be enrolled at MD Anderson.

Ceplene/IL-2 remission maintenance therapy has been shown to significantly prolong Leukemia Free Survival in patients with Acute Myeloid Leukemia (AML) in first complete remission. This is an international, multicenter, open-label study to evaluate the effects of remission maintenance therapy with Ceplene/IL-2 in adult patients with AML in CR1 on specific immune system cells (T and NK cells) and prospectively defined markers of immune response that are known to reflect T and NK cell ability to combat AML.

The primary hypothesis of this research study is that patients in remission undergoing myeloablative haploidentical hematopoietic stem cell transplantation (HSCT) on the Thomas Jefferson University (TJU) 2 Step treatment regimen will have a disease-free survival (DFS) rate at 1 year that is the same or better than the historical DFS of patients with similar diagnoses and ages undergoing matched sibling HSCT. Based on a review of the literature a DFS rate of 50% or better at 1 year would meet the criterion for an effective alternative therapy. A DFS rate of 75% or better would imply superior efficacy of the TJU 2 Step approach over T-replete matched sibling HSCT.

The purpose of this study is to evaluate complete molecular response of Dasatinib in patients for Philadelphia chromosome-positive chronic myeloid leukemia

The primary objective of this study is to determine a safe, tolerable and effective dose of sotatercept that results in the greatest frequency of improvement of anemia in patients diagnosed with low- or intermediate-1 risk myelodysplastic syndromes (MDS) or non-proliferative chronic myelomonocytic leukemia (CMML).

The purpose of this study is to determine the safe dose of EPZ-5676, to evaluate the safety of EPZ-5676 in patients with advanced hematologic malignancies, and to conduct a preliminary assessment of the anti-leukemia activity of EPZ-5676 in patients with acute leukemias bearing rearrangements of the MLL gene. Currently this study is in the MLL-r restricted/expansion phase and is only enrolling patients with rearrangements involving the MLL gene, including 11q23 or partial tandem duplications (PTD).
