ABSTRACT: Aim
The aim of this study was to compare the pharmacokinetics (PK) of DRL_BZ with that of EU-approved (reference medicinal product; RMP) and US-licensed (reference product; RP) bevacizumab (Avastin® ) in healthy male subjects.Methods
In this double-blind, parallel-group, Phase 1 study (BZ-01-001), men aged 20-45 years were randomized 1:1:1 to receive a single intravenous infusion of 1 mg kg-1 of bevacizumab as DRL_BZ, RMP or RP. A total of 149 subjects were randomized (DRL_BZ, 50; RMP, 50; RP, 49). Primary endpoints included maximum observed serum concentration (Cmax ), area under the concentration-time curve from time zero (pre-dose) extrapolated to infinity (AUC(0-?) ), and area under the concentration-time curve from time zero (pre-dose) to last quantifiable concentration (AUC(0-t) ). Secondary objectives were to compare the safety and immunogenicity of DRL_BZ with those of the reference products.Results
Primary PK parameters were comparable across groups, and 90% confidence intervals for the geometric mean ratios of the primary PK endpoints were within the pre-specified equivalence margins (80-125%) for all pairwise comparisons (DRL_BZ vs. RMP, DRL_BZ vs. RP and RMP vs. RP). No deaths or serious adverse events were reported. Similar numbers of subjects reported similar numbers of treatment-emergent adverse events in the three treatment groups. One subject who received DRL_BZ had anti-drug antibodies at the Day 85 visit; however, no anti-drug antibodies were detected in this subject at the 12-month follow-up visit.Conclusions
PK, safety and immunogenicity of DRL_BZ were comparable to EU-approved and US-licensed bevacizumab in healthy male subjects.
