Brief summary: A Randomized, Double-blind, Two-arm, Parallel-group, Single-dose, Phase 1 Study to Compare the Pharmacokinetics, Safety, and Immunogenicity of Subcutaneous CT-P6 and Herceptin in Healthy Male Subjects

Detailed description: CT-P6 SC, containing the active substance trastuzumab in combination with rHuPH20, is being developed by CELLTRION, Inc. (hereafter, the Sponsor) as a proposed biosimilar to the reference product, EU-approved Herceptin SC. The primary amino acid sequences of trastuzumab in CT-P6 SC are identical to those of the reference drug (EU-approved Herceptin SC). The CT P6 drug product will have the same pharmaceutical liquid formulation form and strength as the reference product's vial for SC injection and is intended to have a highly similar quality profile to the reference product.
