Overview

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.

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.

Outcomes

Primary Outcomes

Safety of single and multiple ascending doses of SZEY-2108

Safety and tolerability as assessed through the determination and recording of the occurrence of AEs as well as by adverse changes in vital signs, ECG (e.g. QTc interval) parameters, and laboratory data.

Time frame: Part 1: From the time of signed consent through the end of study date which occurs on Day 7±1;Part 2: From the time of signed consent through the end of study date which occurs on Day 15±1

Secondary Outcomes

Assessment of Pharmacokinetic Parameter (plasma): Cmax measurement

Maximum plasma concentration (Cmax µg/mL) on Day 1 after single infusion , maximum plasma concentration at steady state (Css,max µg/mL) after multiple infusion.

Time frame: In Part 1：0 to 24 hours post-dose on Day 1 ；In Part 2：0 to 24 hours post-dose on Days 1~7 and on the morning of D8 (varied intervals per cohort)

Assessment of Pharmacokinetic Parameter (plasma): AUC

Area under the plasma concentration-time curve from zero extrapolated to infinity (AUC µg\*h/mL) or AUC(0-last) in Part 1 on Day 1 after single infusion, area under the plasma concentration-time curve at steady state after multiple infusion (AUCss µg\*h/mL).

Time frame: In Part 1：0 to 24 hours post-dose on Day 1 ；In Part 2：0 to 24 hours post-dose on Days 1~7 and on the morning of D8 (varied intervals per cohort)
