Cyclophosphamide Treatment Options in Minneapolis, MN

This is a phase II trial designed to test the safety and efficacy (disease free survival \[DFS\]) of related donor HLA-haploidentical NK-cell based therapy for the treatment of acute myelogenous leukemia (AML). The natural killer (NK) cell product will be given to patients 60 years and older who are in a first complete remission after 1 or 2 courses of standard AML induction. After a preparative regimen of cyclophosphamide and fludarabine, patients will receive a single infusion of either CD3-/CD19- NK cells or CD3-/CD56+ NK cells followed by a short course of Interleukin-2 (IL-2) to facilitate NK cell survival and expansion.

Study Design: This is a two-stage Phase II trial investigating the efficacy of Clofarabine, Cyclophosphamide and Etoposide in acute leukemia patients with detectable minimal residual disease (MRD) prior to allo-HCT. The primary objective is to determine the impact of the study treatment in eliminating the presence of minimal residual disease without causing a significant delay of allo-HCT due to treatment related toxicity. The intent of this study is to allow patients to proceed to transplant (independent of this study) within 42 days of Day 1 of Clofarabine based therapy. Read Less

RATIONALE: Giving chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer or abnormal cells and prepares the patient's bone marrow for the 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. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer or abnormal cells (graft-versus-tumor effect). Giving an infusion of the donor's T-regulatory cells before the transplant may help increase this effect. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of umbilical cord blood T-regulatory cell infusion followed by donor umbilical cord blood transplant in treating patients with high-risk leukemia or other hematologic diseases.

RATIONALE: Giving chemotherapy, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood transplant helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T-regulatory cells after the transplant may decrease this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. However, the donor immune system may also react against the recipient's tissues (graft-versus-host disease). PURPOSE: This phase I trial is studying the side effects and best dose of donor T-regulatory cells after an umbilical cord blood transplant in treating patients with advanced hematologic cancer or other disorder.

This is a unique dose-escalation trial that will titrate doses of umbilical cord blood (UCB) Treg and CD3+ Teff cells with the goal of infusing as many CD3+ Teff cells as possible without conferring grade II-IV acute graft-versus-host disease (GVHD). In this study, the investigators propose to add UCB Treg and UCB CD3+ Teff cells to the two TCD UCB donor units with the goal of transplanting as many CD3+ Teff cells as possible without reintroducing risk of acute GVHD. The investigators hypothesize that Treg will permit the reintroduction of CD3+ Teff cells that will provide a bridge while awaiting HSC T cell recovery long term. The co-infusion of Treg will prevent GVHD without the need for prolonged pharmacologic immunosuppression. Read Less

This is a Simon's optimal two-stage phase II trial designed to estimate grade II-IV acute graft-versus-host disease (GVHD) after infusion of T regulatory (nTreg) in a fixed dose ratio to the combined CD3+ cell count of the two graft units in recipients of double UCB transplantation. The nTreg cells (manufactured from a 3rd cord blood unit) are infused on day 0 at least 1 hour after the 2nd unit of the double umbilical cord blood (UCB) transplant. The nTreg cells require an 18 day (±2 days) lead time based on the planned transplant day. The combined CD3+ cell content from the two graft UCB units is enumerated upon thaw (day 0). The patient then receives the number of nTregs cells from the 3rd cord product to achieve a Treg:CD3+ cells ratio of 5:1. The nTreg cell dose depends on the CD3+ cell content of the two graft UCB graft units, but it will not exceed the highest dose level safely tested in the ongoing University of Minnesota phase I Treg dose escalation study MT 2006-01.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Colony-stimulating factors such as filgrastim and sargramostim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Interferon alfa may interfere with the growth of cancer cells. It is not yet known which treatment regimen is more effective for multiple myeloma. PURPOSE: Randomized phase II trial to compare the effectiveness of filgrastim with that of sargramostim plus chemotherapy, peripheral stem cell transplantation, and interferon alfa in treating patients who have multiple myeloma.

RATIONALE: Giving colony-stimulating factors, such as G-CSF, and cyclophosphamide helps stem cells move from the patient's bone marrow to the blood so they can be collected and stored. Chemotherapy and radiation therapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. PURPOSE: This phase II trial is studying how well cyclophosphamide plus filgrastim followed by stem cell transplant works in treating patients with chronic phase or accelerated phase chronic myelogenous leukemia.

RATIONALE: Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from a related or unrelated donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow to make stem cells, red blood cells, white blood cells, and platelets. PURPOSE: This clinical trial is studying how well donor umbilical cord blood transplant works in treating patients with hematologic cancer. Read Less

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. PURPOSE: This phase II trial is studying how well giving filgrastim together with chemotherapy and peripheral stem cell transplant works in treating patients with Hodgkin's lymphoma or non-Hodgkin's lymphoma.

RATIONALE: Giving low doses of chemotherapy, such as cyclophosphamide and fludarabine, and radiation therapy before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving chemotherapy together with total-body irradiation followed by donor umbilical cord blood transplant, cyclosporine, and mycophenolate mofetil works in treating patients with hematologic cancer.
