title: Evaluation of similar biotherapeutic products (SBPs): scientific principles and their implementation.
abstract: The availability of biotherapeutic products to patients has a major impact on the success in treating many life-threatening and chronic diseases. These products are often derived by recombinant DNA technology and are expensive for the majority of patients who need them most. Increasing numbers of patents/data protection are now expiring and biologicals "similar" to the originators (innovative products) are coming to the market. This process is seen as a mechanism for increasing the access to biotherapeutic products which are very much needed for the treatment of chronic diseases worldwide. The emergence of Similar Biological Products (SBPs) has created numerous challenges in developing, licensing, and using these important products. From a public health perspective, the overall expectation is that similar products will be available at an affordable price and will increase patients' access to the therapy. In response to the requests for assistance in defining regulatory requirements for SBPs, the WHO Expert Committee on Biological Standardization (ECBS) adopted the new WHO Guidelines for evaluation of SBPs in October 2009. This article provides a brief account of the WHO initiative to assist its member states to establish national requirements for the regulatory oversight of SBPs. The aim of the article is to inform its readers of the current status of WHO Guidelines on the evaluation of similar biotherapeutic products and of the plan to strengthen national regulatory requirements to assure quality, safety and efficacy of similar biotherapeutic products at the global level.
