Active clinical trials for "Leukemia"

The purpose of this study is to evaluate the safety and the efficacy of cladribine, high-dose cytarabine and idarubicin in the treatment of patients with relapsed acute myeloid leukemia.

In this trial, HLA-A2+ patients with active AML are vaccinated with a peptide from the leukemia-associated antigen WT1 together with immunological adjuvants keyhole limpet hemocyanin (KLH) as T-helper protein and granulocyte macrophage colony stimulating factor (GM-CSF) 4 times bi-weekly, then monthly.

The prognosis of elderly patients with relapsed or refractory acute myeloid leukemia (AML) is grave. Because of their chronological age and/or the presence of multiple co-morbidities, treatment-related mortality in elderly patients with AML is quite high although higher intensive treatment is mandatory to overcome chemoresistant characteristic of their disease. Several regimens have been evaluated as salvage chemotherapy for relapsed or refractory AML such as Mitoxantrone/High dose Cytarabine or Amsacrine/High dose Cytarabine. These regimens could achieve complete remission (CR) in a part of patients, but resulted in higher treatment related mortality (TRM). Accordingly, less intensive salvage regimen is needed for elderly patients with relapsed or refractory AML. The activity of histone deacetylase (HDAC) inhibitor, Vorinostat or Suberoylanilide hydroxamic acid (SAHA), against AML has been suggested in cell line models and in animal model as well as in a phase 1 trial. The phase 1 study determined the MTD of oral Vorinostat as 200mg twice daily or 250mg thrice daily. In addition, the phase 1 trial showed the antitumor activity of Vorinostat with 17% of response rate in patients with advanced leukemia or myelodysplastic syndrome (MDS). Accordingly, further study is recommended to demonstrate the clinical activity of Vorinostat in AML. In terms of the combining drug with Vorinostat, anthracycline is one of the best candidate. A in vitro study demonstrated that the combination of anthracycline (esp. idarubicin) with HDAC inhibitor have significant clinical activity against leukemia. Another candidate is Gemtuzumab ozogamicin, which is a calicheamicin-conjugated antibody directed against CD33 antigen on AML blasts. The U.S. FDA also approved the use of GO in relapsed AML as a monotherapy. A study also showed that the combinational therapy of GO with attenuated doses of standard induction chemotherapy could successfully induce CR without increasing treatment-related mortality in AML patients aged 55 or older. A in vitro study reported that HDAC inhibitor valproic acid augmented the clinical activity of GO toward CD33+ AML cells. The study demonstrated that the strategy using HDAC inhibitor together with GO could potentially induce synergistic proapoptotic activity against AML blasts without increasing toxicity. In our center, so far we treated relapsed or refractory AML patients using the salvage regimen including GO (3mg/m2/dayx1day) plus attenuated Idarubicin/Cytarabine (Idarubicin 12mg/m2/day for 2 days and intermediate dose Cytarabine). So far, the CR rate from the regimen is around 50% without increasing TRM. Accordingly, we will determine the efficacy and toxicity of Vorinostat-incorporating salvage regimen based on the GO+IA chemotherapy in patients 50 years old or older with relapsed or refractory AML.

This study will collect data on safety, effectiveness and patient acceptance of MabCampath treatment under daily life conditions.

The aims of the study are to determine whether single agent imatinib (STI571; Glivec) is more effective as up-front remission induction therapy than conventional multi-agent induction chemotherapy for elderly patients with Philadelphia positive (Ph+)ALL, whether this treatment is better tolerated, and whether subsequent combination therapy with imatinib and chemotherapy of approximately a 1 year duration is tolerable and effective with respect to maintaining remissions.

RATIONALE: Giving combination chemotherapy before a peripheral blood stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood or bone marrow and stored. More chemotherapy or radiation therapy is given prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy and radiation therapy. Interleukin-2 may stimulate the patient's white blood cells to kill cancer cells. PURPOSE: This randomized phase III trial is studying two different regimens of combination chemotherapy, interleukin-2, and peripheral stem cell transplant and comparing them to see how well they work in treating patients with acute myeloid leukemia.

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. PURPOSE: Phase II trial to study the effectiveness of monoclonal antibody in treating patients who have acute myelogenous leukemia that did not respond to standard treatment given in clinical trial PDL 195-301.

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 or bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy followed by bone marrow or peripheral stem cell transplantation in treating patients with acute myelogenous leukemia.

This study is a single-arm, open label, phase I clinical trial to evaluate the safety and feasibility of CD19CAR-T in treatment of relapsed / refractory acute lymphoblasic leukemia.

This study is designed to explore the safety and efficacy of CD7 CAR-T Cells for patients with relapse/refractory CD7+ NK/T cell lymphoma ,T-lymphoblastic lymphoma and Acute Lymphocytic Leukemia. And to evaluate the pharmacokinetics of CD7 CAR-T cells in patients.
