National Control Laboratory Assessment of Quality of Rituximab Biosimilars in India.

In past few years many rituximab (RTX) biosimilars have been launched in India. Biosimilars are products that are similar in terms of quality, safety, and efficacy to its innovator product and are expected to offer improved affordability. The less clinical examination is a significant source of reduction in the cost of development of a biosimilar. However, this clinical relief is predicated on the assumption that there is analytical similarity between the biosimilar and the innovator product. Therefore, the role of National Control Laboratory become very important to ensure the quality of these drugs by carrying out analytical characterization at the point of drug product release level as when referred by National Regulatory Authority for quality evaluation. To assess the similarity between innovator and biosimilars, different physicochemical and biological quality attributes were assessed. A multitude of state-of-the-art analysis of
