Summary

This phase 1 study was designed to evaluate the safety and tolerability of SZEY-2108 in single and multiple intravenous infusions, the pharmacokinetic profile of SZEY-2108 after single and multiple intravenous infusions, and the effect of exposure to SZEY-2108 after a single intravenous infusion on QT/QTc interval. Metabolites in each biological matrix (blood, urine, feces) and excretion characteristics (feces) after SZEY-2108 were analyzed.

Detailed description

This is a first-in-human, randomized, double-blind, placebo-controlled study consisting of 2 parts. Part 1: Single-dose intravenous infusion dose-escalation trial. A total of 44 \~ 52 healthy adult subjects will be enrolled in Part 1 and they will be administrated with SZEY-2108 or placebo by single intravenous infusion. Part 1 consists of 7 cohorts: 100mg，200mg，500mg, 1000mg, 2000mg，4000mg and the dose of last cohort to be determined. Four subjects will be randomized to SZEY-2108 or placebo at a ratio of 1:1 in the 100mg cohort and eight subjects at a ratio of 3:1 in other each cohort. Time for intravenous infusion is 2h±5 min and it may be extended to 3 h±5 min if intolerance occur in 2000mg and 4000mg cohort. Subjects will be randomised to receive an intravenous infusion of SZEY-2108 or placebo on the morning of D1, then they will still be hospitalised for safety, tolerability, pharmacokinetic and C-QTc assessment, and finally will discharge the Phase I clinical study centre after completion of all assessments at D3. They are required to return to the study centre at D7 for a safety follow-up visit. Part 2: Multi-dose intravenous infusion dose-escalation trial According to results of Part 1, administration dose and dosing interval may be adjusted in Part 2. Thirty healthy adult subjects will be enrolled in Part 2 and they will receive multiple doses of SZEY-2108 or placebo by intravenous infusion. Part 2 consists of 3 cohorts: 1000mg at Q8h，2000mg at Q8h, and one dose level of 1000mg, 1500mg or 2000mg at Q6h. Ten subjects will be randomized to SZEY-2108 or placebo at a ratio of 4:1 in each cohort. Time for intravenous infusion is 2h±5 min and it may be extended to 3 h±5 min if intolerance occur in 2000mg cohort. Subjects will be randomized to receive an intravenous infusion of SZEY-2108 or placebo at Q8h or Q6h on D1\~D7 and on the morning of D8. They will still be hospitalised for safety, tolerability and pharmacokinetic assessment, and finally will discharge the Phase I clinical study centre after completion of all assessments at D9 or D10 (for faecal retention group). Subjects are required to return to the study centre at D15 for a safety follow-up visit.
