All-cause mortality is represented as the percentage of participants who died after first dose of study drug through Day 42 from any cause. Participants with unknown survival status through Day 42 were included as deaths in the calculation.

Intent-to-treat population

The DRC was an independent, blinded committee consisting of experts in the field of infectious disease who assessed patients' outcomes. The overall response was based on the DRC-assessed clinical, mycological and radiological responses. Success was defined as the resolution or partial resolution of all attributable clinical symptoms and physical findings, the eradication or presumed eradication of the original causative organism cultured or identified by histology/cytology at Baseline and a > 50% improvement in radiological response from Baseline (or improvement of at least 25% from Baseline for the Day 42 analysis or End of Treatment if it occurred prior to Day 42). End of treatment (EOT) is the last day of study drug administration. For the Day 42 and Day 84 analyses, any visits that the DRC assessed as Not Done were considered a failure for that visit. A death before Day 42 was also considered a failure, even if the DRC assessed the participant to be a success prior to death.

Modified Intent-to-treat (mITT) population consisted of ITT participants who had proven or probable IFD as determined by the DRC.

All-cause mortality is represented as the percentage of participants who died after first dose of study drug through Day 84 from any cause. Participants with unknown survival status through Day 84 were included as deaths in the calculation.

Intent-to-treat population

Overall response based on investigators' assessments was not derived as it was not deemed necessary because participants overall response status was determined by the DRC. All investigators' assessments of clinical, mycological and radiological responses are analyzed separately (see Outcome Measures 8-10).

Blinded assessments of clinical symptoms and physical findings of invasive fungal disease were performed by the independent DRC. Clinical response is defined as the resolution or partial resolution of all attributable clinical symptoms and physical findings. Failure is defined as no resolution of any attributable clinical symptoms and physical findings and/or worsening. Participants with no attributable signs and symptoms present at Baseline and no symptoms attributable to invasive fungal disease (IFD) developed post-baseline were classified as "Not Applicable." End of treatment is the last day of study drug administration.

Modified intent-to-treat population. Any visits the DRC assessed as not done were considered as missing and included as a failure; participants with a Not Applicable assessment were excluded. The number of participants included in the analysis at each time point in indicated by "n".

Blinded mycological assessments of the participant's invasive fungal disease status were performed by the independent DRC using the results from fungal culture and isolation and/or histology/cytology of biopsy or biological fluid samples from the infected site. Mycological response is defined as eradication or presumed eradication of the original causative organism cultured or identified by histology/cytology at Baseline. Failure was defined as persistence or presumed persistence. Participants with no mycological evidence available at Baseline were classified as "Not Applicable". End of treatment is the last day of study drug administration.

Modified intent-to-treat population. Any visits the DRC assessed as not done were considered as missing and included as a failure; participants with a Not Applicable assessment were excluded.

Independent reviews of radiology assessments were completed by radiology experts which were provided to the independent, blinded DRC. Blinded radiological assessments were performed by the DRC. Radiological response is defined as a ≥ 50% improvement from Baseline, or improvement of at least 25% from Baseline for the Day 42 analysis or if end of treatment occurred before Day 42. Participants without any radiology at Baseline were considered "Not Applicable." End of Treatment is the last day of study drug administration.

Modified intent-to-treat population. A participant with no post-baseline radiology data with evidence of radiologic disease at Baseline was considered a failure. Participants with a Not Applicable assessment were excluded. The number of participants included in the analysis at each time point is indicated by "n".

Assessment of clinical symptoms and physical findings of invasive fungal disease were performed by the investigator. Clinical response is defined as the resolution or partial resolution of all attributable clinical symptoms and physical findings. Failure is defined as no resolution of any attributable clinical symptoms and physical findings and/or worsening, or if results were unavailable or the participant was unevaluable. Participants with no attributable signs and symptoms present at Baseline were classified as "Not Applicable." End of treatment is the last day of study drug administration.

Modified intent-to-treat population. Missing data for any participant at any visit was included as a failure; participants with a Not Applicable assessment were excluded. The number of participants included in the analysis at each time point in indicated by "n".

Mycological assessments of the participant's invasive fungal disease status were performed by the investigator using the results from fungal culture and isolation and/or histology/cytology of biopsy or biological fluid samples from the infected site. Mycological response is defined as eradication or presumed eradication of the original causative organism cultured or identified by histology/cytology at Baseline. Failure was defined as persistence or presumed persistence. Participants with no mycological evidence available at Baseline, or no mycological follow-up results available or indeterminate results were classified as "Not Applicable". End of treatment is the last day of study drug administration.

Modified intent-to-treat population. Missing data for any participant at any visit was included as a failure; participants with a Not Applicable assessment were excluded. The number of participants included in the analysis at each time point in indicated by "n".

Radiological assessments were performed by the investigator. Radiological response is defined as a ≥ 50% improvement from Baseline, or improvement of at least 25% from Baseline for the Day 42 analysis or if end of treatment occurred before Day 42. Failure is defined as a < 25% improvement at any time or results not available. Participants with no signs on radiological images at Baseline were considered "Not Applicable." End of Treatment is the last day of study drug administration.

Modified intent-to-treat population. Missing data for any participant at any visit was included as a failure. Participants with a Not Applicable assessment were excluded. The number of participants included in the analysis at each time point is indicated by "n".

The safety analysis set consists of all randomized patients who received at least one dose of study drug according to the study drug that the participant actually received as the first dose. One participant was randomized to isavuconazole but received voriconazole treatment for the first 7 days and is included in the voriconazole arm for safety.
