Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryPercentage of Participants Who Experience One or More Treatment-related Adverse Events (AEs)Up to 14 days after treatment (up to Day 102)
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Treatment-related AEs were determined by the investigator to be related to the drug. The 95% confidence interval (CI) was based on the exact binomial method by Clopper- Pearson.
SecondaryPercentage of Participants Who Have a Favorable Global Clinical Response Through Week 6Up to week 6
A global clinical response is assessed by the investigator as favorable if the participant is alive and has a complete response (CR) or partial response (PR). CR is defined as survival within the prespecified period of observation, resolution of all attributable symptoms and signs of disease, resolution of radiological lesion(s), and documented clearance of infected sites that are accessible to repeated sampling. PR is defined as survival within the prespecified period of observation, improvement in attributable symptoms and signs of disease, improvement of radiological lesion(s), and evidence of clearance of infected sites that are accessible to repeated sampling.
SecondaryPercentage of Participants Who Have a Favorable Global Clinical Response Through Week 12Up to Week 12
A global clinical response is assessed by the investigator as favorable if the participant is alive and has a complete response (CR) or partial response (PR). CR is defined as survival within the prespecified period of observation, resolution of all attributable symptoms and signs of disease, resolution of radiological lesion(s), and documented clearance of infected sites that are accessible to repeated sampling. PR is defined as survival within the prespecified period of observation, improvement in attributable symptoms and signs of disease, improvement of radiological lesion(s), and evidence of clearance of infected sites that are accessible to repeated sampling.
SecondaryPercentage of Participants Who Have a Relapse of Invasive Aspergillosis (IA) at Any Point After Achieving Favorable Global Clinical ResponseUp to 28 days post-treatment (up to Day 116)In participants who achieved favorable global clinical response, relapse of IA is defined as the re-emergence of clinical, radiographic, or other relevant abnormalities indicating IA.
SecondaryAverage Plasma Concentration (Cavg) of POS by Age CohortsPre-dose, Day 1, Weeks 1, 2, 4, 6, 9 and 12
Steady state Cavg was determined by population PK analysis of plasma concentrations obtained pre-dose up to Week 12 for each of Cohorts 1 and 2, as well as the pooled Cohorts 1 and 2. Some participants had 2 Cavg parameter values (1 for IV dosing, 1 for oral dosing).
SecondaryMinimum Plasma Concentration (Cmin) of POS by Age CohortsPre-dose, Day 1, Weeks 1, 2, 4, 6, 9 and 12
Steady state Cmin was determined by population PK analysis of plasma concentrations obtained pre-dose up to Week 12 for each of Cohorts 1 and 2, as well as the pooled Cohorts 1 and 2. Some participants had 2 Cmin parameter values (1 for IV dosing, 1 for oral dosing).
SecondaryMaximum Plasma Concentration (Cmax) of POS by Age CohortsPre-dose, Day 1, Weeks 1, 2, 4, 6, 9 and 12
Steady state Cmax was determined by population PK analysis of plasma concentrations obtained pre-dose up to Week 12 for each of Cohorts 1 and 2, as well as the pooled Cohorts 1 and 2. Some participants had 2 Cmax parameter values (1 for IV dosing, 1 for oral dosing).
SecondaryArea Under the Concentration Time Curve Over the Dosing Interval (AUCtau) of POS by Age CohortsPre-dose, Day 1, Weeks 1, 2, 4, 6, 9 and 12
Steady state AUCtau was determined by population PK analysis of plasma concentrations obtained pre-dose up to Week 12 for each of Cohorts 1 and 2, as well as the pooled Cohorts 1 and 2. Some participants had 2 AUCtau parameter values (1 for IV dosing, 1 for oral dosing).
SecondaryTime to Reach Cmax (Tmax) of POS by Age CohortsPre-dose, Day 1, Weeks 1, 2, 4, 6, 9 and 12
Steady state Tmax was determined by population PK analysis of plasma concentrations obtained pre-dose up to Week 12 for each of Cohorts 1 and 2, as well as the pooled Cohorts 1 and 2. Some participants had 2 Tmax parameter values (1 for IV dosing, 1 for oral dosing).
SecondaryAverage Plasma Concentration (Cavg) of POS by FormulationPre-dose, Day 1, Weeks 1, 2, 4, 6, 9 and 12
Steady-state Cavg was determined by population PK analysis from plasma concentration obtained pre-dose up to Week 12 for each of the POS formulations: IV, PFS and tablet. Some participants may have received more than 1 formulation, and results were only reported when N \> 2.
