A Pharmacokinetic Study Comparing MB02 And EU Avastin® In Healthy Male Volunteers

Healthy Volunteers Clinical Trial

Official title: A Randomised, Double Blind, Two-Arm, Single Dose, Parallel Phase I Study To Compare the Pharmacokinetics, Safety and Immunogenicity of MB02 (a Proposed Bevacizumab Biosimilar Drug) and EU Approved Avastin® in Japanese Healthy Male Volunteers

Status Completed

Clinical Trial Summary

A Randomised, Double Blind, Two-Arm, Single Dose, Parallel Phase I Study To Compare the Pharmacokinetics, Safety and Immunogenicity of MB02 (a Proposed Bevacizumab Biosimilar Drug) and EU Approved Avastin® in Japanese Healthy Male Volunteers.

During the course of the study, the similarity in pharmacokinetics will be assessed by sampling the levels of drug in the blood, and by comparing these levels among the different administration arms. Safety, tolerability, and immunologic response to the administered drugs will also be evaluated throughout.

Clinical Trial Description

The primary PK parameter endpoint is AUC(0-∞) for bevacizumab. The secondary PK endpoints will include all other PK parameters for bevacizumab, including Cmax, tmax, t1/2, CL and AUClast.

The serum PK parameters of 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 AUClast. 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 (CI) will be derived for the comparisons of the PK parameters as follows:

• MB02 versus EU Avastin®

A mixed effects model with treatment arm as fixed effect will be used to compare natural-logarithmic transformed PK parameters (AUC[0-∞+, AUClast and Cmax) between the two treatment arms (MB02 vs EU-approved Avastin®)

PK similarity between arms will be concluded if the 90% confidence intervals (CIs) for the geometric mean test/reference ratio of AUC(0-∞) fell within the predefined 0.80-1.25 bioequivalence interval.

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 version 5.0. 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). Each AE will be coded using the Medical Dictionary for Regulatory Activities. All safety data will be listed and summarised as appropriate.

Immunogenicity data (overall 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® (Day -1) and at scheduled post-dose assessments will be presented by treatment arm. All safety data and immunogenicity data summaries will be based on the safety analysis population. Select analyses may be repeated for subsets with or without ADA and de novo ADA formation as appropriate. ;
