Insmed Incorporated Presents Positive IPLEX(TM) Data At ENDO 2006

BOSTON--(BUSINESS WIRE)--June 27, 2006--Insmed, Inc. (NASDAQ: INSM - News): Insmed, Inc. (NASDAQ: INSM - News) today announced new study results that show that IPLEX(TM) (mecasermin rinfabate (rDNA origin) injection) is effective in increasing growth and improving glycemic control in patients with severe insulin-resistance syndromes, specifically Leprechaunism and Type A syndrome. In another clinical trial, once-daily treatment with IPLEX significantly improved height velocity in children with severe primary insulin growth factor-I (IGF-I) deficiencies. A third study of the pharmacokinetics of IPLEX in normal adults showed positive results, with simultaneous increases in IGF-I and IGFBP-3 and without undue increases in "free" IGF-I. Findings of all three studies were presented this week at the annual meeting of the Endocrine Society, ENDO 2006.
