Filter by:Due to the poor outcome of patients with invasive fungal infections (IFI), a more effective prevention of these infections in such patients is wanted. These experiences in intensively treated elderly patients with acute leukemia are especially worrying. This pilot study is designed to collect information on the safety (and efficacy) of an antifungal preventative therapy with an AmBisome® loading dose regimen of 7 mg/kg/week, in four weekly administrations, during the aplastic phase following the start of chemotherapy for acute lymphoblastic leukemia in elderly patients, which is a high risk period for severe fungal infections.
A fixed-dosing regimen of voriconazole is routinely used as prophylaxis against aspergillosis in liver transplant patients admitted to the transplant intensive care unit at UPMC. We hypothesize that use of a fixed-dosing regimen of voriconazole will lead to a large degree of variability in drug exposure among liver transplant patients due to: 1) variability in absorption and elimination caused by physiological characteristics unique to this patient population 2) its non-linear pharmacokinetics and 3) the potential for polymorphism in the genes that encode for cytochrome P-450 enzymes that metabolize voriconazole. This is a pilot clinical pharmacokinetic evaluation that will: 1) characterize the plasma concentration versus time profile of voriconazole in liver transplant patients receiving a fixed-dosing regimen to assess for extremes in systemic exposure 2) determine the oral bioavailability of voriconazole in liver transplant patients 3) assess for functionally significant allelic variation of the cytochrome P-450 enzymes that metabolize voriconazole (CYP2C9, CYP2C19 and CYP3A4/5) in both recipient blood and allograft tissue that may contribute extremes in systemic exposure among liver transplant patients. This evaluation will allow for an assessment of the adequacy of the prophylactic regimen in achieving therapeutic drug concentrations in all subjects. Additionally, the utility of genotyping as a clinical tool to identify patients at risk for extremes in voriconazole exposure will be evaluated. The characterization of the pharmacokinetics in liver transplant patients may be utilized to define an optimal therapeutic regimen that will be individualized to target specific concentrations to maximize efficacy and minimize side-effects.
RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Pemetrexed disodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine together with pemetrexed disodium may kill more cancer cells. PURPOSE: This was planned as a phase I/II trial studying the side effects and determining the best dose of gemcitabine hydrochloride when given together with pemetrexed disodium. Unfortunately, due to a lack of funding, the phase II portion was never conducted.
This phase I trial is studying the side effects and best dose of giving PDX101 together with 17-AAG in treating patients with metastatic or unresectable solid tumors or lymphoma. PDX101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving PXD101 together with 17-AAG may kill more cancer cells.
RATIONALE: Voriconazole and caspofungin acetate may control invasive fungal infections in patients who have weakened immune systems. PURPOSE: This phase II trial is studying how well giving voriconazole together with caspofungin acetate works in treating invasive fungal infections in patients with weakened immune systems.
Therapeutic options for serious fungal infections are limited by intrinsic and acquired resistance to existing antifungal agents. For example, zygomycetes (such as Mucor spp.) are intrinsically resistant to voriconazole and caspofungin. Yet, the only available therapeutic option, amphotericin, is associated with significant renal toxicity, even in lipid formulations. Posaconazole is a new antifungal drug, not yet Food and Drug Administration (FDA) approved, but which has excellent in vitro activity against some intrinsically resistant fungi such as the zygomycetes. The intent of this trial is to provide access to posaconazole to patients with serious fungal infections which are refractory to standard antifungal therapies or invasive fungal infections for which there are currently no effective therapies. Secondly, the drug will also be made available to patients with invasive fungal infections who: - have experienced serious or severe toxicities while receiving standard antifungal therapies; - have pre-existing renal dysfunction which precludes use of standard antifungal therapies; or - are chronically immunosuppressed with a history of invasive fungal infections previously treated with posaconazole in other clinical trials, and who require oral antifungal suppressive therapy as maintenance treatment to prevent recurrence. This is a multicenter, open-label, non-comparative experimental treatment use protocol. The experimental treatment use protocol will provide the investigational medication posaconazole where no other drug is commercially available. Posaconazole is given as an orally or enterally administered suspension. The duration of therapy is at the discretion of the investigator. Safety assessments will include an electrocardiogram [ECG] (to ensure no QTc interval prolongation) performed at baseline and serum/urine pregnancy testing performed at baseline and every three months after initiation of therapy. Plasma concentrations will be obtained if there is evidence of clinical failure. No other tests will be performed specifically for the experimental treatment use protocol.
The purpose of this study is to determine the efficacy of the drug, HuMax-CD4, in patients with mycosis fungoides(MF) and sezary syndrome who are intolerant to or do not respond to treatment with Targretin® and one other standard therapy.
This phase I trial is studying the side effects and best dose of giving tanespimycin together with bortezomib in treating patients with advanced solid tumors or lymphomas. (Accrual for lymphoma patients closed as of 11/27/09) Drugs used in chemotherapy, such as tanespimycin, work in different ways to stop cancer cells from dividing so they stop growing or die. Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. It may also increase the effectiveness of tanespimycin by making cancer cells more sensitive to the drug. Combining tanespimycin with bortezomib may kill more cancer cells.
RATIONALE: Ultraviolet light therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. It is not yet known whether ultraviolet light therapy is more effective with or without bexarotene in treating mycosis fungoides. PURPOSE: Randomized phase III trial to compare the effectiveness of ultraviolet light therapy using methoxsalen with or without bexarotene in treating patients who have mycosis fungoides.
Phase I/II trial to study the effectiveness of combining interleukin-12 with interleukin-2 in treating patients who have mycosis fungoides. Biological therapies, such as interleukin-12 and interleukin-2, use different ways to stimulate the immune system and stop cancer cells from growing. Combining more than one biological therapy may kill more tumor cells
