Trial ID Title Status Sponsor Phase Summary
NCT03590600 ↗ A Single Ascending Dose Study of BTZ043 Completed German Center for Infection Research Phase 1 This study is a randomized, double-blind, placebo-controlled, single ascending dose study to evaluate safety, tolerability, and pharmacokinetics of single doses of BTZ043 in healthy adult volunteers. The study is conducted at a study centre in Germany. Up to 50 male and female participants will be included in this study in up to 5 cohorts; each cohort will consist of 10 subjects: in each cohort 8 subjects will be assigned to BTZ-043 and 2 to placebo. The doses tested will be: 125mg, 250mg, 500mg, 1000mg and 2000mg. Safety will be assessed via regular vital sign measurement, 12-lead ECG parameters, physical examination and safety laboratory assessments. Subjects will be hospitalized from Day -1 until discharge in the morning of Day 3. After completion of all Day 3 assessments of a cohort, blinded safety data will be reviewed and the next dose increment will be decided by the Trial Steering Committee (TSC).
