The FDA has approved Tercica's Increlex (mecasermin [rDNA origin] injection) for the long-term treatment of growth failure in children with severe primary IGF-1 (insulin-like growth factor-1) deficiency (IGFD) or with growth hormone gene deletion who have developed neutralizing antibodies to growth hormone. Increlex is identical to IGF-1, the natural hormone produced in the body that has a broad range of activity central to growth and metabolism.
