The "elusive DMOAD": Aggrecanase inhibition from laboratory to clinic

Clin Exp Rheumatol. 2019 Sep-Oct;37 Suppl 120(5):130-134. Epub 2019 Oct 15.

Abstract

From the time of their discovery in 1999, the aggrecanases, and ADAMTS-5 in particular, have been heavily investigated as targets for disease-modifying osteoarthritis drug (DMOAD) development. Here, we provide a brief narrative review of the discovery efforts to target these enzymes, and how this led to the current ongoing programmes that hold promise for the future. We discuss a comparison of inhibition of collagen breakdown versus inhibition of aggrecan breakdown. We then summarise existing programmes that target ADAMTS-5, including small molecule inhibitors, monoclonal neutralising antibodies and nanobodies, and gene editing technologies. We also briefly discuss the potential analgesic effects this strategy may offer in addition to its joint-protective effects.
