Active clinical trials for "Hematologic Neoplasms"

Patients with refractory or relapsed hematologic malignancies will receive CP-4055 intravenously(IV) on Day 1-5 every three weeks until complete response or disease worsening/progressing

The aim of the study is to obtain immune reconsitutuion as well as reduction of infective episodes and disease relapse in patient with haematological malignancies who underwent SCT(and subsequent T lymphocytes infusions) and selectively controlling GvHD.

Cytokine-induced killer ( CIK ) cells have been shown by our lab to be cytolytic against both autologous and allogeneic acute myeloid leukemia ( AML ) cells. Large scale expansion of CIK cells has also been shown to be feasible in healthy allogeneic stem cell donors as well as in patients undergoing mobilization for autologous transplant. Donor lymphocyte infusion (DLI) has been shown to be active against some haematological malignancies including CML, AML, MDS,NHL and Hodgkin's disease. These donor lymphocytes can be further activated in vitro to become CIK cells. At least 2 other centers in the world have given allogeneic CIK cells for patients relapsing post allogeneic transplant for a variety of haematological malignancies. These early reports have demonstrated feasibility, absence of increased GVHD and possible efficacy in some cases. We are proposing a Phase I /II study on the feasibility / efficacy of immunotherapy with allogeneic CIK cells for patients who relapse after allogeneic marrow transplant for their haematological malignancies. These patients have to be either refractory to conventional donor lymphocyte infusion, or need a larger number of donor lymphocyte than could be provided by unmanipulated donor lymphocytes. Donor lymphocytes will be collected and cultured in GMP facilities to maturity, then infused into patients. This will be given in graded doses at 4 weekly intervals and continued on in the absence of GVHD till remission is achieved or disease progression occurs. Patients may receive various forms of chemotherapy appropriate to the clinical condition in each case before the allogeneic CIK infusion. Efficacy will be assessed by comparing the response to allogeneic CIK infusion vs that to due to conventional DLI, ie response to the two different treatment using DLI response as the comparator. We expect about 10 such cases to be done over the next 3 years. Significant statistics is unlikely to be generated but observation and description of the response can generate useful information for presence or not of the efficacy of such a treatment. If clinical efficacy and superiority over conventional DLI is demonstrated, then future allogeneic CIK may take the place of DLI in this group of poor prognosis patients who relapse after allogeneic transplant .

Primary Objectives: To determine whether aerosolized ribavirin is effective when given at an intermittent dose over 3 hours every 8 hours for therapy of RSV upper respiratory tract infection (URI) and whether it can prevent progression to pneumonia. To determine the effect of this regimen on persistence of viral shedding.

This is an open-label, single arm study. Approximately 3-30 patients will be enrolled. Patients will receive Oral ciclopirox olamine (aqueous suspension), initial starting dose of 5 mg/m2/day administered as a single dose daily for 5 days. Three patients will initially be treated at each dose level in sequential cohorts. Dose escalation will continue for each subsequent cohort based on toxicity and plasma drug concentrations observed during the previous cohort. Dose escalation will continue until establishment of the maximum tolerated dose (MTD) has been met. Patients who have demonstrated response to treatment, up to 6 total cycles of treatment may be administered. If additional cycles are warranted, ciclopirox olamine will be given at the same dose and frequency as the patient initially received.

The purpose of this study is to look at whether the combination of lower-dose chemotherapy with two chemotherapy (anti-cancer) drugs, called busulfan and melphalan, and an antibody medication called alemtuzumab (Campath®), can prevent rejection of donor blood stem cells so that those cells take hold and build a healthy new blood cell factory after transplant. The study will also look at the safety of the combination of drugs and of the transplant of peripheral blood stem cells from a healthy relative or an unrelated donor.

This is a phase II trial of reduced intensity conditioning with Bu/Flu/ATG in pediatric patients with hematologic malignancies at high risk for transplant related mortality with standard transplantation. Patients qualify based on organ system dysfunction, active but stable infection, history of previous transplant or late stage disease. We plan to enroll 45 patients through the Pediatric Blood and Marrow Transplant Consortium (PBMTC) and anticipate that the outcome of the trial will pave the way for phase II or III disease specific protocols addressing efficacy of the approach compared to standard transplant approaches in better risk patients.

This is a phase I open label study to evaluate safety and efficacy of P1446A-05 in subjects with advanced refractory malignancies. Subjects of solid tumors or hematologic malignancies will be included. This is a dose escalation study following an accelerated titration design. It is expected that around 50 subjects would be enrolled in the study.Safety assessment will be conducted on the basis of vital signs, physical examination and laboratory investigations undertaken at regular intervals as per the schedule.

The objective of this study is to compare the safety and efficacy of ABLC versus oral Posaconazole in the prevention of invasive fungal infections in high risk patients with hematologic malignancies or hematopoietic stem cell transplant. Primary objective is to demonstrate the low toxicity rate and low rate of invasive fungal infections associated with ABLC or Posaconazole prophylaxis. Secondary objective will be to compare the cost effectiveness of these two prophylactic regimens.

The goals of the study are (Phase I) to determine the appropriate dose for Clofarabine with Busulfan as a full-intensity conditioning (Clo/BU4 regimen) prior to transplant and then (Phase II) to investigate the safety and effectiveness of this regimen as a conditioning for stem cell transplant in the treatment of aggressive hematologic malignancies in subjects where more conventional approaches are failing.
