A Pharmacokinetic Study Comparing EG1206A and Perjeta (Pertzumab) in Healthy Male Volunteers

Study Overview
=================
Brief Summary
-----------------
This trial is a single-center, single-dose, double-blind, parallel-group, randomized, 3-arm PK trial in healthy male volunteers comparing a biosimilar pertuzumab (EG1206A) to a single intravenous (i.v.) infusion to both European Union (EU) and United States of America (US) reference products.

Detailed Description
-----------------
This trial is part of a clinical development program developing a biosimilar pertuzumab, comparing the PK, safety and tolerability and immunogenicity of pertuzumab after a single intravenous (i.v.) infusion. It assess the bioequivalence, PK characteristics, safety and tolerability as well as the immunogenicity of a test preparation containing 420 mg pertuzumab (EG1206A EirGenix Pertuzumab) as compared to marketed reference (EU and US) after a single dose i.v. infusion over 60 minutes in fasted state.
