These observations are likely dose-related adverse effects of balicatib. Although catK was originally thought to be expressed only in osteoclasts, it has more recently also been found in lung and dermal fibroblasts and been implicated in the degradation of the extracellular matrix in the lung and the skin. It is therefore plausible that the observed dermal fibrosis in balicatib-treated patients is a result of impaired degradation of extracellular matrix proteins and may represent a class effect of catK inhibitors. We recommend that further exploration of catK inhibition for the treatment of osteoporosis or cancer should include monitoring for similar adverse effects.

Abstract

These observations are likely dose-related adverse effects of balicatib. Although catK was originally thought to be expressed only in osteoclasts, it has more recently also been found in lung and dermal fibroblasts and been implicated in the degradation of the extracellular matrix in the lung and the skin. It is therefore plausible that the observed dermal fibrosis in balicatib-treated patients is a result of impaired degradation of extracellular matrix proteins and may represent a class effect of catK inhibitors. We recommend that further exploration of catK inhibition for the treatment of osteoporosis or cancer should include monitoring for similar adverse effects.
