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

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.
