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.
This is a non-comparative, open, multisite prospective estimation study to evaluate the efficacy and safety of caspofungin in the prophylactic treatment of adults who have received an orthotopic liver transplant and are at high risk of developing an invasive fungal infection. It is expected that the proportion of high-risk liver transplant recipients who develop a documented (proven or probable per European Organization for Research and Treatment of Cancer/Mycoses Study Group [EORTC/MSG] modified criteria) invasive fungal infection during the first 100 days after the onset of prophylaxis with caspofungin will be lower than 15%. It is also expected that the incidence of serious drug-related adverse events will be less than 25%.
This is an open-label study of MK0991 in children between 3 to 24 months of age with new onset fever and neutropenia. The purpose of the study is to investigate plasma drug levels of caspofungin.
The purpose of this study is to optimize the management of patients treated for invasive fungal infections by establishing a real-time, continuous clinical data base that will capture and monitor trends in the epidemiology, diagnosis, treatment and outcomes of invasive fungal infections; reflect routine clinical management of patients with invasive fungal infections in order to evaluate treatment and provide a rationale for future treatment paradigms; and allow physicians to assess adherence to institutional clinical practice guidelines, validate current standardized definitions for patients with invasive fungal infections and promote change where appropriate.
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 amount of voriconazole in the brain by fluorine-magnetic resonance spectroscopy (MRS) and to compare brain levels to plasma levels.
