| DrugBank Description: | 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 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. |

| DrugBank 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. |
| DrugBank Pharmacology: | Mecasermin rinfabate promotes vertical growth in pediatric patients in a similar fashion to . is a biosynthetic (recombinant DNA origin) form of human insulin-like growth factor 1 (IGF-1) designed to replace natural IGF-1 in pediatric patients who are deficient, promoting normalized statural growth. Growth hormones (GH) bind to growth hormone receptors (GHR) in the liver and other tissues, which stimulates the synthesis of IGF-1. In target tissues, IGF-1 activates the IGF-1 receptor, resulting in intracellular signals that stimulate growth . Although many actions of the GH are mediated through IGF-1, the precise roles of GH and IGF-1 have not been fully elucidated. Patients with severe primary IGF-1 deficiency (Primary IGFD) fail to produce adequate levels of IGF-1, due to disruption of the GH pathway used to promote IGF-1 release (possible GH pathway disruptions include mutations in the GHR, post-GHR signaling pathway, and IGF-1 gene defects. The structure of IGFBP-3 remains unsolved. |
| DrugBank MoA: | Mecasermin rinfabate supplies recombinant-DNA-origin IGF-1 (rhIGF-1) bound to recombinant-DNA-origin IGFBP-3. 80% of IGF-1 is naturally bound to IGFBP-3 so the binding of rhIGF-1 to rhIGFBP-3 increases the half life of rhIGF-1 compared to . rhIGF-1 binds to the Type I IGF-1 receptor. This receptor exerts intra-cellular signaling activity in a number of processes involved in statural growth, including mitogenesis in multiple tissue types, chondrocyte growth and division along cartilage growth plates, and increases in organ growth. |
