Active clinical trials for "Leukemia, Myeloid, Acute"

The combination of clofarabine and cytarabine is an effective and reasonably well-tolerated treatment regimen in patients with either relapsed/refractory or newly diagnosed AML. For this prospective study, we propose the use of clofarabine and cytarabine for second course induction therapy for patients with persistent AML after treatment with an anthracycline and cytarabine.

This phase I/2 trial studies the side effects and best dose of activated natural killer cells in treating patients with relapsed or refractory acute myeloid leukemia and myelodysplastic syndromes. Giving chemotherapy before a donor natural killer cell infusion helps stop the growth of cancer cells and stops the patient's immune system from rejecting the donor's natural killer cells. Modified natural killer cells may help the body build an immune response to kill cancer cells. Aldesleukin (interleukin-2) may stimulate the white blood cells (including natural killer cells) to kill leukemia cells. In the phase II and pediatric portion of the study, the investigators intend to use maximal tolerated or tested (MT/TD) CIML NK cell dose as determined from the phase I part of this study. The phase II portion of the study also replaces IL-2 with ALT-803. The rationale for this change is to support the donor derived NK cells in vivo after adoptive transfer. Update with Amendment 16: The first two patients treated in the Phase II ALT-803 lead in cohort experienced a set of symptoms consistent with cytokine release syndrome (CRS).The Phase II ALT-803 lead in cohort was closed and a decision was made to return to rhIL-2 support for the remainder of enrollments in the Phase II portion of the study.

The goals of this study are to learn about the effectiveness, the side-effects, if waiting to give the idarubicin and cytarabine may change the side effects or effectiveness, and to identify factors to predict for responses to this therapy. The trial will examine combination of three chemotherapy drugs. These drugs are decitabine, idarubicin, and cytarabine.

The primary aim of this protocol is to evaluate if the one-year survival is significantly improved in the group of patients who receive a T-cell replete haploidentical donor hematopoietic cell transplant (HCT) with a novel reduced intensity conditioning regimen. Study population will consist of patients (21 years or under) with hematologic malignancies that have relapsed or are refractory after prior allogeneic transplant. Toxicity will be evaluated by the rate of transplant related mortality and the rates of moderate and severe graft-versus-host disease (GvHD) at day 100. The investigators will describe event-free, and disease-free survival at one year, as well as the rates of hematopoietic recovery and donor engraftment and study comprehensively immune reconstitution following T-cell replete haploidentical transplantation.

This Phase 1/2 study consists of two parts. The purpose of Part 1 of the study is to examine the safety and tolerability of AKN-028 and to determine the recommended dose of AKN-028 for further evaluation in Part 2 of the study in patients with Acute Myelogenous Leukemia (AML). The purpose of Part 2 of the study is to determine safety and efficacy in patients with AML.

The purpose of this study is compare the efficacy of haplo-cord transplant (investigational arm) with that of a more commonly used procedure in which only the cells contained in one or two umbilical cords are infused (standard arm). We hypothesize that reduced intensity conditioning and haplo-cord transplant results in fast engraftment of neutrophils and platelets, low incidences of acute and chronic graft versus host disease, low frequency of delayed opportunistic infections, reduced transfusion requirements, shortened length of hospital stay and promising long term outcomes. We also hypothesize that umbilical cord blood selection can prioritize matching and better matched donors can be identified rapidly for most subjects.

This is a study of MK-8242 alone and in combination with cytarabine in adult participants with refractory or recurrent acute myelogenous leukemia (AML). The study will have 2 Arms. Arm A is for participants with refractory or recurrent AML who are considered ineligible for standard chemotherapy. In Part 1 of Arm A, participants will receive MK-8242 monotherapy in escalating doses to determine the recommended phase 2 dose [RP2D]. In Part 2, participants will receive monotherapy with MK-8242 to confirm the RP2D and assess preliminary efficacy. Arm B is for participants with recurrent AML following an initial complete remission (CR) or CR with incomplete marrow recovery (CRi) of 6 to 12 months duration. In Part 1 of Arm B, participants will receive MK-8242 in escalating doses + cytarabine to determine the RP2D in combination with cytarabine. In Part 2, participants will receive MK-8242 + cytarabine to confirm the RP2D and assess preliminary efficacy. The pharmacokinetics of MK-8242 will be studied in both arms. With Amendment 4 (22 August 2013) a 21-day dosing cycle is added, with MK-8242 being given on Days 1-7 of each 21-day cycle in both the monotherapy and combination therapy arms; data from Arm A will be used to determine whether a participant receives 21-day or 28-day therapy in Arm B.

The purpose of this open label study is to evaluate the safety, tolerability, pharmacokinetics, and efficacy of AZD1208 in patients with recurrent or refractory Acute Myelogenous Leukemia (AML). This study will have two parts. In Part A, patients will receive escalating doses to identify the maximum tolerated dose (MTD). In Part B, the efficacy of the maximum tolerated dose will be evaluated in a expanded group of patients.

The purpose of this study is to determine whether PD-616 in combination with low-dose Cytarabine is safe and effective in the treatment of untreated or relapsed/refractory acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (MDS).

In this phase I extension study, the investigators seek to test the safety of both higher doses of plerixafor as well as intravenous dosing to maximize inhibition of the target, CXCR4.
