A Pharmacokinetic Study Comparing MB02 And US And EU Avas... | NCT03293654

Description Module

Detailed Description

The primary PK parameters are Cmax and AUC(0-∞). The PK parameters for bevacizumab will be calculated using standard noncompartmental methods. An analysis of covariance model will be used to analyse the log-transformed primary PK parameters (AUC[0-∞].and Cmax) and AUC(0-t). The model will include a fixed effect for treatment and body weight as a covariate.

All other PK parameters will not be subject to inferential statistical analysis. Estimates of geometric mean ratios together with the corresponding 90% confidence intervals will be derived for the comparisons of the PK parameters as follows:

MB02 versus EU Avastin®
MB02 versus US Avastin®
EU Avastin® versus US Avastin®

PK similarity will be achieved if the 90% confidence intervals (CIs) for the biosimilar-to-reference ratios of PK endpoints (AUC[0-∞] and Cmax) fall within the predefined 0.80-1.25 acceptance similarity criteria for all 3 pairwise comparisons; MB02 versus EU-approved Avastin®; MB02 versus US-licenced Avastin®; and EU-approved Avastin® versus US-licenced Avastin®.

All AEs will be listed and summarised using descriptive methodology. All observed or patient-reported AEs will be graded by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. The incidence of AEs for each treatment will be presented by severity and by association with the study drugs as determined by the Investigator (or designee). All safety data will be listed and summarised as appropriate

Immunogenicity data (overall anti-drug antibody [ADA] incidence and titers, and neutralising ADA results) will be listed. A summary of the number and percent of subjects testing positive for ADA or neutralising antibodies before the dose of MB02, EU Avastin®, or US Avastin® (Day 1) and at scheduled postdose assessments will be presented by treatment arm.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Cmax: Maximum Observed Serum Concentration	To compare the pharmacokinetic (PK) profiles of MB02, US Avastin® and EU Avastin® (in terms of Cmax) to establish bioequivalence between the 3 study arms. For the PK similarity assessments, regulatory guidelines on bioequivalence were followed whereby two treatments are judged not to be different from one another if the 90% confidence interval (CI) for the geometric LS means ratios are fully contained within the predefined bioequivalence limits of 0.80 to 1.25.	Predose, 1.5 h after end of infusion, 2, 3, 4, 5, 6, 8, 12, 24 h post-dose on Day 1-8, Day 10, Day 14, Day 21, Day 28, Day 42, Day 56, Day 78, and Day 100.
AUC(0-∞); Area Under the Serum Concentration-time Curve From Time Zero to Infinity	To compare the pharmacokinetic (PK) profiles of MB02, US Avastin® and EU Avastin® (in terms of AUC[0-∞]) to establish bioequivalence between the 3 study arms. For the PK similarity assessments, regulatory guidelines on bioequivalence were followed whereby two treatments are judged not to be different from one another if the 90% confidence interval (CI) for the geometric least square means (GLSM) ratios are fully contained within the predefined bioequivalence limits of 0.80 to 1.25.	Predose, 1.5 h after end of infusion, 2, 3, 4, 5, 6, 8, 12, 24 h post-dose on Day 1-8, Day 10, Day 14, Day 21, Day 28, Day 42, Day 56, Day 78, and Day 100.

Secondary Outcomes

Measure	Description	Time Frame
Tmax: Time of Maximum Observed Serum Concentration	To evaluate the tmax of MB02, US Avastin® and EU Avastin® .	Predose, 1.5 h after end of infusion, 2, 3, 4, 5, 6, 8, 12, 24 h post-dose on Day 1-8, Day 10, Day 14, Day 21, Day 28, Day 42, Day 56, Day 78, and Day 100.
AUC(0-t) = Area Under the Serum Concentration-time Curve From Time Zero to the Time of the Last Observable Concentration;

Other Outcomes

Measure	Description	Time Frame
AUC(0-∞) Adjusted: Protein-adjusted Area Under the Serum Concentration-time Curve From Time Zero to Infinity	Due to variability in the actual protein content between the study drugs and study drug batches which had the potential to influence the study results (as AUC is a dose-dependent PK parameter), protein-adjusted AUC(0-∞) was also derived for each individual by dividing each parameter by the actual protein content of the product batch that the individual subjects received. The 3 mg/kg IV dose of MB02 and US Avastin®, MB02 and EU Avastin®, and EU and US Avastin® were all considered bioequivalent in terms of the protein-adjusted AUCs and Cmax as the 90% CI for the geometric LS means ratios were fully contained within the predefined bioequivalence limits of 0.80 to 1.25 for all 3 comparisons. In general, as assessed from the geometric CV%, between-subject variability remained similar following protein adjustment compared to the unadjusted AUCs and Cmax.
