Filter by:Prospective use of RT-PCR for PML/RARa might be used to guide a total tehrapy approach in APL, including refined diagnosis, front-line treatment, assessment of response and anticipated salvage therapy for patients who undergo molecular relapse.
This phase I trial is studying the safety and potential efficacy of infusing non-human leukocyte antigen (HLA) matched ex vivo expanded cord blood progenitors following treatment with clofarabine and cytarabine for patients with acute myeloid leukemia (AML). The combination of clofarabine, cytarabine (Ara-C) and granulocyte colony-stimulating factor (G-CSF) has been tested in earlier studies for the treatment of acute myeloid leukemia. In these previous clinical trials, this combination of drugs has been shown to have an anti-leukemia effect. However, the combination of clofarabine and Ara-C is profoundly myelosuppressive and immunosuppressive causing periods of neutropenia potentially lasting more than three weeks. During this period, patients are at increased risk of infections that can result in an increased risk of death. G-CSF is a growth factor that is used to help the white blood cells recover more quickly, but even with G-CSF, the use of clofarabine and Ara-C is often limited by the need to take long breaks between treatments to allow blood counts to recover. In our lab we have developed a method of growing or "expanding" blood stem cells (cells that give rise to the blood system) from umbilical cord blood. We are doing this study to find out if giving these expanded cells after chemotherapy is safe, helps the blood system recover more quickly from chemotherapy to allow shorter breaks between treatments, and decreases the risk of infection
This research study is looking at biomarkers in DNA samples from patients with acute lymphoblastic leukemia or acute myeloid leukemia. Studying samples of DNA from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.
Subjects have acute promyelocytic leukemia (APL) that has come back (relapsed) after initial treatment or has not gone away with initial therapy. This research study involves testing an investigational drug called Tamibarotene in combination with standard treatment for relapsed APL called arsenic trioxide. Tamibarotene has been approved in Japan to treat patients with relapsed APL since April 2005. Tamibarotene is in the same family of drugs as all-trans retinoic acid (ATRA), a medication that subjects received previously in their treatment. ATRA and tamibarotene both cause the APL cells to differentiate (or become) normal non-leukemia cells. Laboratory studies of tamibarotene have shown to be effective in APL. The purpose of this study is to determine if tamibarotene in combination with arsenic trioxide is safe and effective.
The study will compare the efficacy of the 2 treatments in intermediate and high-risk APL patients in achieving first hematological complete remission and molecular remission.
For relapsed acute promyelocytic leukemia after all-trans retinoic acid (ATRA) and arsenic treatment, remission can be achieved by chemotherapy with ATRA and/or arsenic and addition of mylotarg. Autologous hematopoietic cell transplantation using a polymerase chain reaction (PCR) negative graft is important treatment option to obtain sustainable remission. This study is to test the efficacy and the safety of conditioning regimen with idarubicin and busulfan for relapsed Acute Promyelocytic Leukemia (APL).
The purpose of this study is to test the safety of sorafenib and vorinostat when given together to see what effects (good and bad) it has on the patient and their acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). This study is also being done to find the highest dose of sorafenib and vorinostat that can be given together without causing severe side effects.
This phase III trial is studying combination chemotherapy to see how well it works in treating young patients with newly diagnosed acute promyelocytic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.
This is a Phase I study designed to determine the MTD and assess the toxicity associated with clofarabine followed by fractionated cyclophosphamide in patients > 1 year of age or < 21 years of age with relapsed or refractory acute leukemias. There will be 25 to 35 patients enrolled. Cohorts of 3 to 6 patients each will receive escalated doses of clofarabine followed by fractionated cyclophosphamide until the MTD is reached. There will be no intra-patient dose escalation. Single-agent cyclophosphamide will be administered by 2-hour IVI on Day 0 of cycle 1. On Days 1, 2, and 3 and Days 8, 9, and 10 clofarabine will be administered by IVI 2 hours before each dose of cyclophosphamide (see the treatment schema below). A cycle is defined as 28 days.
The purpose of this study is to determine whether NRX 195183 is effective in the treatment of relapsed or refractory Acute Promyelocytic Leukemia
