Study of Cyclodextrin (SBECD) and Voriconazole Blood Concentrations During Continuous Dialysis

This study has been completed.

This study's primary objective is to determine if continuous renal replacement therapy (CRRT) can adequately remove the sulfobutylether-ß-cyclodextrin sodium (SBECD) vehicle from the blood so that intravenous voriconazole can be utilized in critically ill patients with renal dysfunction requiring dialysis. Secondarily, the pharmacokinetics of intravenous voriconazole and its metabolite (UK121-265) and adverse effects of SBECD accumulation will also be evaluated. The study hypothesis is that CRRT is effective at removing SBECD and allows patients to receive intravenous voriconazole without the concern of SBECD accumulation.

Condition Intervention Phase

Further study details as provided by University of Colorado, Denver:

Primary Outcome Measures:
  • Determine SBECD plasma and effluent concentrations [ Time Frame: Days 1-7 ]
    Evaluate SBECD pharmacokinetics (Cmax, Cmin, AUC, half-life, CL, seiving coefficient). Predict time to SBECD accumulation in study patients

Secondary Outcome Measures:
  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: Days 1-30 ]
  • Determine Voriconazole and UK121-265 plasma and effluent concentrations [ Time Frame: Days 1-7 ]
    Voriconazole and UK121-265 Pharmacokinetics will be evaluated (Cmax, Cmin, AUC, elimination rate constant, half-life, CL, seiving coefficient) including determination and impact of any CYP2C19 mutations on plasma pharmacokinetic parameters

Biospecimen Retention:   Samples With DNA
Whole blood, serum, urine, effluent fluid from dialysis machine
