Trial Outcomes & Findings for Safety and Pharmacokinetics of Rezafungin (NCT NCT04117607)

NCT ID: NCT04117607

Last Updated: 2021-07-16

Results Overview

Each subject is only counted once per toxicity grade for the worst severity recorded. Vital sign parameters include systolic blood pressure (BP), diastolic BP, heart rate, respiratory rate, and temperature. Thresholds for abnormal vital signs were considered as systolic BP \>= 141 mmHg or \<= 89 mmHg, diastolic BP \>= 91 mmHg, heart rate \<= 54 bpm (baseline \>= 60 bpm) or \<=50 (baseline \< 60 bpm) or \>= 101 bpm, respiratory rate \>= 23 breaths per minute, and temperature \>= 38.0 degrees Celsius. If a vital sign result met the threshold for an AE at baseline, subsequent vital sign results were only considered to be an AE if the grading worsened in severity.

Each subject is only counted once per toxicity grade for the worst severity recorded. Vital sign parameters include systolic blood pressure (BP), diastolic BP, heart rate, respiratory rate, and temperature. Thresholds for abnormal vital signs were considered as systolic BP \>= 141 mmHg or \<= 89 mmHg, diastolic BP \>= 91 mmHg, heart rate \<= 54 bpm (baseline \>= 60 bpm) or \<=50 (baseline \< 60 bpm) or \>= 101 bpm, respiratory rate \>= 23 breaths per minute, and temperature \>= 38.0 degrees Celsius. If a vital sign result met the threshold for an AE at baseline, subsequent vital sign results were only considered to be an AE if the grading worsened in severity.
