Stamulumab (MYO-029[1]) is an experimental myostatin inhibiting drug developed by Wyeth Pharmaceuticals for the treatment of muscular dystrophy. MYO-029 was formulated and tested by Wyeth in Collegeville, Pennsylvania.[2] Myostatin is a protein that inhibits the growth of muscle tissue, MYO-029 is a recombinant human antibody designed to bind to and inhibit the activity of myostatin.[3]

Stamulumab is a G1 immunoglobulin antibody which binds to myostatin and prevents it from binding to its target site, thus inhibiting the growth-limiting action of myostatin on muscle tissue. Research completed in 2002 found that Stamulumab might one day prove to be an effective treatment for Duchenne muscular dystrophy[4]

[edit] Phase 1 and 2 Trials

  • Wyeth undertook a Phase 1 and 2 clinical trial in 2005 and 2006 of MY0-029. The multiple ascending dose trial (36 patients per cohort) contained some measures of efficacy. The trial's participants included people afflicted with Facioscapulohumeral muscular dystrophy, Becker's muscular dystrophy, and Limb-girdle muscular dystrophy. Through 2007 Wyeth has been analyzing the results but the hoped-for news and/or a publication in 2007 did not occur. [2][5][6]. However, as of January 24, 2008, the study has been accepted by a peer-reviewed journal and publication is expected "in the next few months.... publication is there now, it shows no success!!"[7]

[edit] Related

  • ACVR2B is similar to Stamulumab but is not an antibody; rather, it provides a portion of the molecule to which myostatin would normally bind thus preventing the myostatin from binding with the actual molecule[8].
