- Brief Summary
The purpose of this study is to evaluate the pharmacokinetics of 14C-labeled cleavage product (BAL8728), in particular the routes of excretion and extent ot metabolism of the cleavage product following administration of a single intravenous dose of pyridinylmethyl-14C-labeled prodrug isavuconazonium sulfate (BAL8557). In addition, identify the metabolic profile of BAL8728 in human plasma, urine and/or feces after a single intravenous dose of pyridinylmethyl-14C-labeled BAL8557 and evaluate the pharmacokinetics of BAL8728 and BAL4815. Safety and tolerability after a single intravenous dose of pyridinylmethyl-14C-labeled isavuconazonium sulfate will also be evaluated.

- Primary Outcome Measures
Name Time Method Radioactivity in emesis (if applicable) After study drug administration up to Day 9 Radioactivity ratio blood/plasma Day 1 Percent of dose and cumulative percent of dose of radioactivity recovered in urine 7 time intervals up to Day 4. If Day 4 is not the end of the study, sample collection will continue in 24 hour intervals until discharge up to Day 9 Percent of dose and cumulative percent dose of radioactivity recovered in feces 4 time intervals up to Day 4. If Day 4 is not the end of the study, sample collection will continue in 24 hour intervals until discharge up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: AUCinf 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: AUClast 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: Cmax 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: tmax 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: total body clearance after intravenous dosing (CLtot) 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: volume of distribution during terminal phase after intravenous dosing (Vz) 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in plasma: t 1/2 20 time points up to Day 4. If Day 4 is not the end of the study, samples will be drawn once a day up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in urine: amount excreted (Ae) 7 time intervals up to Day 4. If Day 4 is not the end of the study, sample collection will continue in 24 hour intervals until discharge up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in urine: percent of unchanged drug excreted into the urine (Ae%) 7 time intervals up to Day 4. If Day 4 is not the end of the study, sample collection will continue in 24 hour intervals until discharge up to Day 9 Pharmacokinetics of BAL8728 (cleavage product) in urine: renal clearance (CLr) 7 time intervals up to Day 4.
