Filter by:Acute myelogenous leukemia (AML) arises from leukemia stem cells that are difficult to eradicate and serve as a reservoir for disease relapse following chemotherapy. A promising area of investigation is the development of immunotherapeutic approaches that stimulate the immune system to recognize leukemia stem cells as foreign and eliminate them. The purpose of this research study is to determine the safety of the Dendritic Cell AML Fusion Vaccine (DC AML vaccine) after participants have achieved a remission with chemotherapy. In this clinical trial, patients are treated with a tumor vaccine alone following standard of care chemotherapy. The DC AML vaccine is an investigational agent that tries to help the immune system to recognize and fight against cancer cells. It is hoped that DC AML vaccine will prevent or delay the disease from coming back.
A phase IIa study to evaluate the pharmacokinetic and efficacy of amonafide L-malate (AS1413) in combination with cytarabine in treating patients with acute myeloid leukemia (AML)
This phase II trial is studying the side effects and how well giving fludarabine phosphate, busulfan, anti-thymocyte globulin followed by donor peripheral blood stem cell transplant, tacrolimus, and methotrexate works in treating patients with myeloid malignancies. Giving chemotherapy, such as fludarabine phosphate and busulfan, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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 anti-thymocyte globulin before transplant and tacrolimus and methotrexate after transplant may stop this from happening.
The current understanding of PR104 justifies the evaluation of PR104 in subjects with relapsed/refractory AML and ALL. These include: - Hypoxia. Leukemic bone marrow is likely to demonstrate a level of hypoxia sufficient to activate PR104 to its active metabolites PR104H and PR104M. - Myelotoxicity as the primary toxicity at MTD. In prior clinical studies in subjects with solid tumors PR104 has demonstrated myelotoxicity as the primary toxicity. This observation suggests that PR104 will exert a similar effect on leukemic cells. - AKR1C3. AML has been reported to exhibit high levels of AKR1C3 which should lead to selective activation of PR104 within both hypoxic and oxic leukemic cells. - Preclinical data. PR104 has demonstrated impressive activity in an initial study using primary human ALL in a mouse model. The initial dose finding phase of the study will provide estimates of the activity and toxicity of PR104 in subjects with refractory/relapsed AML, and determine the optimal individualized dose to give each subject based on his/her covariates (prior CR duration, prior number of salvage therapies, age). Once a potentially beneficial dose has been determined, an expanded cohort of subjects with AML or ALL will receive PR104 at a uniform dose. This information will prove valuable in defining the future clinical development of PR104, and in determining if PR104 has sufficient activity and acceptable safety in AML to warrant future phase II or phase III studies in this indication. Primary objectives - Determine the toxicities and recommended dose of PR104 when administered IV to subjects with relapsed/refractory AML and ALL. Secondary objectives - Evaluate the pharmacokinetics (PK) of PR104 and a series of PR104 metabolites - Evaluate any anti-tumor effects of PR104 - Evaluate the expression of AKR1C3 in bone marrow and leukemic cells - Evaluate potential biomarkers of hypoxia
There is no curative therapy once acute leukemia patients relapse after transplant. Patients who develop clinically significant graft versus host disease (GVHD) have a lower rate of relapse than those who do not develop GVHD. We are initiating this study of post-transplant fast withdrawal of immunosuppression and donor lymphocyte infusions, with a goal of achieving full donor chimerism in children with hematologic malignancies. If our hypothesis that full donor chimerism results in leukemia-free survival is correct, using immune modulation to achieve full donor chimerism should decrease relapse rate and thus increase survival. The goal of this Phase II study is to identify if achieving full donor chimerism in whole blood CD3+ and leukemia-specific (CD14/15+, CD19+, CD33+ and CD34+) subset may decrease the risk of relapse of patients undergoing allogeneic transplant for hematologic malignancy.
This study is designed to test the combination of Plerixafor with G-CSF for chemosensitization in patients with relapsed or refractory AML.
RATIONALE: Studying samples of tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at tissue and blood samples from patients with acute myeloid leukemia.
This research trial studies multidrug resistance genes in patients with acute myeloid leukemia. Studying samples of bone marrow or blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors learn more about drug resistance and how patients respond to treatment.
RATIONALE: Collecting and storing samples of tissue and blood from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at changes in the DNA of tissue samples that were collected from patients with acute myeloid leukemia.
Cord blood transplantation (CBT) is an alternative option for patients with pediatric acute leukemia that indicated stem cell transplantation. Although CBT is as affective as unrelated bone marrow transplantation with lower graft versus host disease (GVHD) severity and incidence, transplantation related mortality (TRM) has been major problems after myeloablative conditioning. To reduce TRM, CBT with non-myeloablative conditionings have been performed but not so satisfactory especially for engraftment rate. Recently reduced toxicity myeloablative conditioning regimen was developed with promising result in adult bone marrow or mobilized peripheral blood transplantation. To increase the engraftment potential with low TRM rate, reduced toxicity myeloablative conditioning composed of fludarabine, intravenous busulfan plus thymoglobulin is planned for pediatric patients with acute myeloid leukemia.
