Maximum Age

Inclusion Criteria:

  • Subject diagnosed with IA or IM. A positive diagnosis is defined as follows:
    • Proven, probable or possible IFI per the European Organisation for Research and Treatment of Cancer/Mycoses Study Group [EORTC/MSG], 2008 criteria Note: Subjects with "possible" IFI will be eligible for enrollment; however, diagnostic tests to confirm the invasive fungal disease as "probable" or "proven" according to the EORTC/MSG criteria should be completed within 10 calendar days after the first dose of study drug
    • Note: In addition to the criteria set for mycological criteria by the EORTC/MSG in 2008, and only for subjects with an underlying hematologic malignancy or recipients of hematopoietic stem cell transplant (HSCT) who also have clinical and radiologic features consistent with invasive fungal infection, the following are acceptable:
    • Galactomannan (GM) levels (optical density index) meeting the below criteria are acceptable mycological evidence for enrollment or upgrading the diagnosis to probable IA:
      • A single value for serum or bronchoalveolar lavage (BAL) fluid of ≥ 1.0 or
      1. Two serum GM values of ≥ 0.5 from two separate samples
  • Subject has sufficient venous access to permit intravenous administration of study drug or the ability to swallow oral capsules
  • A female subject is eligible to participate if not pregnant and at least one of the following conditions applies:
    • Not a subject who is of childbearing potential, OR
    • Subject who is of childbearing potential who agrees to follow a contraceptive guidance throughout the treatment period and for at least 30 days after the final study drug administration
  • Subject and subject's parent(s) or legal guardian agree that the subject will not participate in another interventional study while on treatment with the exception of oncology trials
  • Exclusion Criteria:

    • Subject has familial short QT syndrome, is receiving medications that are known to shorten the QT interval, or has a clinically significant abnormal ECG
    • Subject has evidence of hepatic dysfunction defined as any of the following:
      • Total bilirubin (TBL) ≥ 3 times the upper limit of normal (ULN)
      • Alanine transaminase (ALT) or aspartate transaminase (AST) ≥ 5 times the ULN
      • Known cirrhosis or chronic hepatic failure
    • Subject has used strong cytochrome P450 (CYP3A4) inhibitors or inducers such as ketoconazole, high dose ritonavir, rifampin/rifampicin, long acting barbiturates (e.g., phenytoin), carbamazepine and St. John's Wort in the 5 days prior to the first dose of study drug
    • Subject has another IFI other than possible, probably or proven IA or IM
    • Subject has chronic aspergillosis, aspergilloma or allergic bronchopulmonary aspergillosis
    • Subject has received mould active systemic antifungal therapy, effective against the primary IMI, for more than four days during the seven days preceding the first dose
      • Note: Prior use of prophylactic antifungal therapy is acceptable. In case of breakthrough IA while on prophylactic mould-active azole class drugs, additional documentation will be required to be submitted to the sponsor medical monitor or designee to approve subject enrollment
    • Subject has known history of allergy, hypersensitivity or any serious reaction to any of the azole class antifungals, or any components of the study drug formulation
    • Subject has any condition which makes the subject unsuitable for study participation
    • Subject is unlikely to survive 30 days
    • Subject has received investigational drug, with the exception of oncology drug trials, or trials with investigational drugs treating graft versus host disease, within 28 days or five half-lives, whichever is longer, prior to screening
