A biosimilar medicine is a highly similar (but not identical) version of an original biological medicine. There is no meaningful difference in its safety, quality and effectiveness compared to the original biological medicines. All biosimilar medicines must be approved by the TGA after analysis of data regarding their safety, quality, consistency and effectiveness.
