300 mg posaconazole twice on Day 1, either by oral tablet or IV solution; followed by 300 mg once daily for up to 84 days

Voriconazole

Drug

300 mg voriconazole oral tablet (or 6 mg/kg IV solution) twice on Day 1, followed by 200 mg oral tablet (or 4 mg/kg IV solution) twice daily for up to 84 days

Primary outcomes

  1. Number of Participants With an Adverse Event

    Time frame: Up to approximately Day 98

    An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol specified procedure, whether or not considered related to the medicinal product or protocol specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the Sponsor's product is also an AE.

Secondary outcomes

  1. Percentage of Participants With Successful Overall Response for Invasive Aspergillosis in Cohort 2 at Day 42

    Time frame: Day 42

    Successful treatment (or successful overall response) is defined as complete response and partial response to treatment assessed by the clinical adjudication committee (CAC). The 95% confidence interval (CI) is based on the Clopper-Pearson exact method.

  2. Percentage of Participants With Successful Overall Response for Invasive Aspergillosis in Cohort 2 at Day 84

  3. Percentage of Participants With Successful Overall Response for Chronic Pulmonary Aspergillosis in Cohort 2 at Day 42

    Time frame: Day 42

    Successful treatment (or successful overall response) is defined as favorable response to treatment assessed by CAC. The 95% CI is based on the Clopper-Pearson exact method.

  4. Percentage of Participants With Successful Overall Response for Chronic Pulmonary Aspergillosis in Cohort 2 at Day 84

    Time frame: Day 84

    Successful treatment (or successful overall response) is defined as favorable response to treatment assessed by CAC. The 95% CI is based on the Clopper-Pearson exact method.

  5. Percentage of Participants With Successful Overall Response for Invasive Aspergillosis and Chronic Pulmonary Aspergillosis in Cohort 2 at End of Trial (Day 84)

    Time frame: Day 84

    Successful treatment (or successful overall response) for invasive aspergillosis is defined as complete response and partial response to treatment assessed by CAC. Successful treatment (or successful overall response) for chronic pulmonary aspergillosis is defined as favorable response to treatment.The 95% CI is based on the Clopper-Pearson exact method.

  6. Percentage of Participants With Successful Overall Response for Zygomycosis in Cohort 2 at Day 42

    Time frame: Day 42

    Zygomycosis is an infection caused by zygomycete fungi. Successful treatment (or successful overall response) is defined as complete response and partial response to treatment assessed by CAC. The 95% CI is based on the Clopper-Pearson exact method.
