Overview

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.

Inclusion Criteria

  • The subject has a body weight of at least 45 kg and a body mass index of 18 to 32 kg/m2, inclusive.
  • The subject's 12-lead electrocardiogram (ECG) is normal at Screening and Day -1; or, if abnormal, the abnormality is not clinically significant. The ECG for the subject has a QTcF of at least 360 but not more than 430 msec.

Exclusion Criteria

  • The subject has any clinically significant disease history of the following systems: pulmonary, gastrointestinal, cardiovascular (including a history of clinically significant arrhythmia), hepatic, neurological, psychiatric, renal, genitourinary, endocrine, metabolic, dermatologic, immunologic, hematologic, or malignancy excluding non melanoma skin cancer.
  • The subject has a positive test for hepatitis B surface antigen or hepatitis C antibodies at Screening or is known to be positive for human immunodeficiency virus.
  • The subject has a known or suspected allergy to any of the azole class of compounds, or a history of multiple and/or severe allergies to drugs or foods or a history of severe anaphylactic reactions.
  • The subject has used tobacco or nicotine containing products in the last 6 months prior to Day -
  • 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.
