MENLO PARK, Calif., Nov. 14, 2011 /PRNewswire/ -- Virobay, Inc., a privately held biotechnology firm with a broad portfolio of cysteine protease inhibitors for the treatment of autoimmune diseases, neuropathic pain, liver diseases and cancer, presented data showing that one of the company's spectrum-selective cathepsin inhibitors demonstrated efficacy in a mouse model of bone cancer pain. Virobay has a series of advanced, spectrum-selective cathepsin inhibitors with structural diversity and demonstrated activity in bone cancer and related pain. VBY-825, a prototype compound within this series, is an orally bioavailable, highly potent, reversible inhibitor of a subset of cathepsin proteases (including cathepsins S, K, L and B) that demonstrated protection from bone destruction and remodeling in this metastatic breast cancer model, as well as significant analgesic activity. These preclinical data suggest that Virobay's spectrum-selective cathepsin inhibitors have potential therapeutic utility in the treatment of metastatic and primary bone cancer and cancer-related bone pain, with a mechanism of action that would be highly complementary to standard chemotherapy.
The data were presented in a poster, titled "Efficacy of a Spectrum-Selective Cathepsin Inhibitor in a Mouse Model of Bone Cancer," by Holsinger, et al., at the AACR-NCI-EORTC International Conference: Molecular Targets and Cancer Therapeutics, on Sunday, November 13th.
"These preclinical data provide a compelling demonstration of the therapeutic potential of Virobay's cathepsin inhibitors in bone cancer and bone cancer pain," said Robert Booth, PhD, Virobay's president and chief executive officer. "The data demonstrate that the anti-tumorigenic and analgesic activity is due to the selective targeting of specific cathepsins that are known to facilitate osteolytic metastasis, bone invasion and bone matrix degradation. We believe that these dat
