An Update on the Registration of Biosimilars in Malaysia.

Background: Because of its structure and complex manufacturing process, every biotherapeutic product (BTP; medicinal products made by or derived from living organisms and produced by biotechnology) adheres to stringent quality assurance and control requirements, in addition to extensive nonclinical and clinical study data. Similarly, copy products of original biotherapeutics (termed as "biosimilars") are subjected to equally strict regulatory control. BTPs have been registered in Malaysia since the 1990s; however, registration of biosimilars started only in 2008.
