PARIS--(BUSINESS WIRE)--Regulatory News: Ipsen (Paris:IPN), today announced preliminary results from a Phase II open-label clinical trial (MS316 study) that evaluates the co-administration of recombinant human growth hormone (rhGH) and recombinant human insulin-like growth factor-1 (rhIGF-1) in two separate daily injections as a potential treatment for children with otherwise unexplained short stature associated with low IGF-1 levels. Ipsen also announced results from a long-term study of rhIGF-1 (study 1419) in patients with severe primary insulin-like growth factor deficiency (sPIGFD) that demonstrated that long-term twice-daily therapy with rhIGF-1 improved the adult and near adult heights of extremely short patients with sPIGFD. The data from these two studies were presented along with posters on rhIGF-1 (Increlex®, mecasermin [rDNA origin] injection) at the 8th Joint Meeting of the Lawson Wilkins Pediatric Endocrine Society / European Society for Pediatric Endocrinology (LWPES/ESPE) in New York, NY.
