A Study to Evaluate the Pharmacokinetics of BAL8728 After a Single Dose of Pyridinylmethyl-14C-Labeled Isavuconazonium Sulfate in Healthy Male Subjects

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.

  • The subject has used tobacco or nicotine containing products in the last 6 months prior to Day -1.
  • The subject has had treatment with prescription drugs, over-the-counter medication, or complementary and alternative medicines within 14 days prior to Day -1, with the exception of occasional use of acetaminophen up to 2 g/day.
  • The subject has participated in any interventional clinical study or has received any investigational agent within 28 days or 5 half-lives, whichever is longer, prior to Screening.
  • The subject has had any significant blood loss, donated one unit (450 mL) of blood or more, or received a transfusion of any blood or blood products within 60 days or donated plasma within 7 days prior to clinic admission on Day -1.

    Time frame: 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

  4. Radioactivity in whole blood and in plasma: Time to Attain Cmax (tmax)

    Time frame: 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
