Brief summary

The purpose of this study is to compare the efficacy and safety of isavuconazole versus voriconazole in the treatment of patients with invasive aspergillosis.

Detailed description

Acute invasive fungal infections caused by aspergillus, zygomycetes and other filamentous fungi remain life threatening diseases. Early treatment with highly effective anti-fungals reduces mortality. This study investigates the efficacy and safety of isavuconazole in the treatment of invasive fungal diseases, caused by Aspergillus or other filamentous fungi.

Interventions

DRUGIsavuconazole

Loading doses were administered as IV infusion and maintenance doses were administered as IV infusion or oral (capsules).

Percentage of Participants With a Radiological Response Assessed by the Investigator

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.

Time frame: Day 42, Day 84 and End of Treatment. The median duration of study drug administration was 45 days.

Population: 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.
