Outcomes

Primary Outcomes

Number of Participants With an Adverse Event

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.

Time frame: Up to approximately Day 98

Secondary Outcomes

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

Time frame: Day 42

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

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.

Time frame: Day 84

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