A Study to Compare Pharmacokinetic and Safety of TRS003 to China-approved Bevacizumab and US-licensed Avastin®

Study Overview
=================
Brief Summary
-----------------
This is a 12-week, randomized, double-blind, single-dose pharmacokinetic (PK) study. Approximately 114 healthy male participants (screening occurred within 28 days prior to dosing) will be randomized 1:1:1 to either TRS003, China-approved bevacizumab, and US-licensed Avastin® groups. Study drug will be dispensed as a single 3 mg/kg dose for intravenous infusion within 90 minutes. PK and immunogenicity samples will be collected and safety will be assessed. The primary objective of this study was to demonstrate pharmacokinetic similarity between TRS003, China-approved bevacizumab and US-licensed Avastin®, as measured by AUC0-inf in healthy male participants after a single 3 mg/kg dose.

Detailed Description
-----------------
The primary assessment of PK similarity will be based upon a 90 percentage confidence interval (CI) for the ratio of the geometric means (TRS003, China-approved bevacizumab and US-licensed Avastin®) for AUC0-inf on PK analysis set. If the 90 percentage CI of the ratio of the geometric means for AUC0-inf is within the range of 80-125 percentage, then PK similarity will be concluded. Secondary PK parameters such as but not limited to Cmax, AUClast will be analyzed using the same statistical approach. A nonparametric approach, for example, Wilcoxon signed-rank test, will be taken to evaluate parameters such as t1/2. Exploratory analyses may be performed for other PK parameters as deemed appropriate. All adverse events (AEs) will be listed and summarized using descriptive methodology. The incidence of AEs for each treatment will be presented by severity and association with the study drugs. Clinical laboratory parameters, vital signs, and electrocardiogram (ECG) parameters will be listed and summarized using descriptive statistics. The number and percentage of participants testing positive for anti-drug antibodies (ADAs) will be summarized by treatment and time point.
