Filter by:Allogeneic stem cell transplantation, the only known curative modality for CML, was abandoned in recent years for a very effective and much less toxic targeted therapy with the tyrosine kinase inhibitors (TKIs). However, approximately one third of patients still need another treatment including stem cell transplantation. The study protocol comprised a cohort of consecutive patients with CML who received allogeneic stem cell transplantation using partial T cell depletion, with no post-transplant GvHD prophylaxis. Forty consecutive patients with CML underwent allogeneic stem cell transplantation from a matched sibling using partial T cell depletion (TCD), in a single institution. Escalated dose of donor lymphocyte infusion (DLI) was given in case of either relapse or presence of minimal residual disease (MRD) as detected by cytogenetic or molecular analysis. The purpose of the study is to decrease transplant-related toxicity.
This research study is for people with a specific type of leukemia called Philadelphia chromosome positive acute lymphoblastic leukemia (the type the patients have). The investigators plan to give you combination of 3 drugs (dasatinib, mitoxantrone, cytarabine) for the first part of the chemotherapy (called Induction). The investigators have previously shown that the combination of mitoxantrone and cytarabine is very effective in your kind of leukemia. The purpose of this study is to establish a safe dose range of dasatinib in combination with this standard induction chemotherapy based on side effects. If possible, the trial will also give us an idea of how well this combination might work in treating your leukemia. Previous studies have shown that dasatinib can produce responses when given alone for your kind of leukemia. By using the dasatinib together with the chemotherapy, the investigators believe that we can kill even more leukemia cells than with either treatment alone. The investigators will initially treat patients with a low dose of dasatinib and monitor for side-effects. If the initial group of patients is able to tolerate this low-dose of dasatinib, then future patients will receive higher doses of dasatinib. Mitoxantrone and cytarabine chemotherapy is the standard therapy at the investigators' institution for the patient's leukemia and it is the combination of dasatinib with this chemotherapy that is new and investigational in this study.
Patients with acute lymphoblastic leukemia and positivity for the breakpoint cluster region-Abelson murine leukemia (BCR-ABL) protein or the Philadelphia chromosome have a poor prognosis with standard chemotherapy. The prognosis seemed to improve following the adition of imatinibe, a BCR-ABL inhibitor, to the treatment but still a substantial amount of patients relapse or progress during treatment. Nilotinib is a BCR-ABL inhibitor more potent than imatinib. It has been shown to be effective against most of the cells that bear mutations of the BCR-ABL protein leading to resistance to imatinibe. The investigators' hypothesis is that the addition of nilotinib to a standard chemotherapy for acute lymphoblastic leukemia (ALL) will translate into more rapid BCR-ABL reduction and effectiveness against imatinib-resistant clones leading to less relapses and better survival.
This study will evaluate a gene expression signature (Growth Factor Signature [GFS]) as a biomarker for response/resistance to BRC-ABL oncogene inhibitors.
Standard therapy with Imatinib (IM) significantly prolongs the survival of Ph+CML patients who obtain a complete cytogenetic response (CCgR). Elderly patients (i.e., at least 65 years) have similar cytogenetic responses and survival, but they usually show a low compliance. The aim of the study is to evaluate the percentage of elderly patients who maintain a CCgR with intermittent imatinib therapy with respect to standard daily administration.
RATIONALE: Nilotinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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 nilotinib together with combination chemotherapy may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving nilotinib together with combination chemotherapy works in treating patients with newly diagnosed acute lymphoblastic leukemia.
RATIONALE: Dasatinib and vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving dasatinib together with vorinostat may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of dasatinib when given together with vorinostat in treating patients with accelerated phase or blastic phase chronic myelogenous leukemia or acute lymphoblastic leukemia.
This is a two-part safety and efficacy study of SKI-606 in subjects who have Philadelphia chromosome positive leukemias (CML). Part 1 will be a dose-escalation study, in which an escalating dose of SKI-606 (Bosutinib), up to 600 mg, will be studied in subjects with imatinib resistant/refractory or imatinib intolerant chronic phase CML. Part 2 will evaluate the safety and efficacy of the maximum tolerated dose (MTD) of SKI-606 (Bosutinib)identified in Part 1 of the study.
The purpose of this study is to determine the maximum tolerated dose (MTD) of TAK-901 in subjects with advanced hematological malignancies, and to further assess the safety and tolerability of TAK-901 at or below the MTD in an expanded cohort of subjects in order to select a dose for future studies.
Patients not previously exposed to imatinib and with resistant or refractory Ph+ ALL, lymphoid blast crisis chronic myelogenous leukaemia (LBC CML) or with de novo Ph+ ALL and aged over 55y were eligible in the study. The DIV regimen consisted in one IV injection of vincristine 2 mg combined with 2 days of dexamethasone 40 mg PO repeated weekly for 4 weeks as induction and then monthly for 4 months as consolidation. Imatinib was administered at 800 mg per day during the induction period and at 600 mg/d continuously during consolidation. Patients in CR not eligible for HSCT were allocated to maintenance therapy consisting in weekly SC injection of Pegasys 45 µg and continuous administration of imatinib 400 mg per day for 2 years.
