          Abstract

          The concept of similar biological medicinal products (‘biosimilar’ medicinal products) allows pharmaceutical companies to develop products based on an abridged dossier once the marketing protection of the ‘reference’ biological medicinal product has expired. A biosimilar medicinal product can be granted a marketing authorization provided that its similarity to a reference product is established in terms of quality, safety and efficacy (step-wise comparability exercise). A decision to launch a biosimilar medicinal product on the market is taken if it has a similar efficacy and comparable or better (less) immunogenicity than the chosen reference biological medicinal product. However, this decision is based on limited data and the comparability program may detect substantial differences in immunogenicity profiles but is likely incapable of detecting rare events. This is why clinical experience, through clinical trials and extensive pharmacovigilance programs, remains the most reliable way to assess the immunogenicity and tolerance profile of recombinant therapeutic proteins. Substitution of one biological medicinal product by a biosimilar medicinal product is not currently recommended before long-term clinical efficacy and safety have been acquired in all relevant populations. Here we review recent regulatory guidelines provided by EMEA and comment on the marketing authorizations and risk management plans of two recently approved biosimilar somatropins.

          Plasma insulin-like growth factor-I and prostate cancer risk: a prospective study.

          Insulin-like growth factor-I (IGF-I) is a mitogen for prostate epithelial cells. To investigate associations between plasma IGF levels and prostate cancer risk, a nested case-control study within the Physicians' Health Study was conducted on prospectively collected plasma from 152 cases and 152 controls. A strong positive association was observed between IGF-I levels and prostate cancer risk. Men in the highest quartile of IGF-I levels had a relative risk of 4.3 (95 percent confidence interval 1.8 to 10.6) compared with men in the lowest quartile. This association was independent of baseline prostate-specific antigen levels. Identification of plasma IGF-I as a predictor of prostate cancer risk may have implications for risk reduction and treatment.

              IGF-binding proteins--the pieces are falling into place.

              The six insulin-like growth factor (IGF)-binding proteins (IGFBPs) are important regulators of IGF actions. IGF-independent actions of several IGFBPs have also been described. IGFBPs contain highly conserved N- and C-terminal domains, both of which are important for high-affinity IGF binding. The C-domain also binds a large number of other biomolecules, thereby modulating IGF binding and mediating IGF-independent effects. The 3D structures of the IGF-binding region of the N-domain of IGFBP-5 and the entire C-domain of IGFBP-6 have been solved recently, providing new insights into IGFBP modulation of IGF actions, and structural studies might be expected to do the same for IGF-independent actions. IGFBP-based therapies for diseases such as cancer are promising, and this recent progress will enhance their development.
