Drug evaluation: apratastat, a novel TACE/MMP inhibitor for rheumatoid arthritis.

Abstract

Wyeth Research was developing apratastat (TMI-005), one in a series of dual TNFalpha-converting enzyme and matrix metalloprotease-13 inhibitors, for the potential treatment of inflammation, especially rheumatoid arthritis. By January 2005, apratastat had entered a phase II clinical trial; however, in October 2006, Wyeth reported that it had terminated development of the drug because of lack of efficacy in this trial.
