Mecasermin rinfabate

Overview

Mecasermin rinfabate is approved for severe primary insulin-like growth factor (IGF) deficiency or in patients with GH gene deletion who have developed antibodies to growth hormone (GH). Mecasermin rinfabate is similar to Mecasermin in that both drugs contain recombinant DNA origin insulin-like growth factor 1 (IGF-1). Mecasermin rinfabate however, is already bound to recombinant DNA origin insulin-like growth factor binding protein 3 (IGFBP-3). The binding of IGF-1 to IGFBP-3 is said to extend the half life and reduce the clearance of IGF-1 in patients with growth hormone resistant syndromes and low levels of IGFBP-3 though this may represent <500 patients worldwide. Mecasermin rinfabate manufactured by Insmed Incorporated under the brand name Iplex was approved by the FDA in 2005. In 2007 Insmed withdrew their application for a marketing authorization with The European Medicines Agency.

Indication

Mecasermin rinfabate was approved for treatment of severe primary insulin-like growth factor (IGF) deficiency or in patients with GH gene deletion who have developed antibodies to growth hormone (GH). Severe primary IGF-1 deficiency is defined by: A) height standard deviation (SD) score less than or equal to 3 SD below normal B) basal IGF-1 SD score less than or equal to 3 SD below normal C) normal or above normal levels of growth hormone In 2007, Insmed (Mecasermin rinfabate's manufacturer) made an agreement with Tercica (Mecasermin's manufacturer) that Mecasermin would no longer be available for this indication but could be developed for non short stature conditions such as severe insulin resistance, myotonic muscular dystrophy, and HIV associated adipose redistribution syndrome.

Associated Conditions
