Galeterone (TOK-001, formerly called VN/124-1) is a potent anti-androgen with three modes of action. The compound acts as a specific androgen receptor antagonist, inhibits CYP17 lyase while conserving CYP17 hydroxylase function, and decreases overall androgen receptor levels in prostate cancer cells. Galeterone is a first in class, multi-targeted small-molecule drug that disrupts the growth and survival of prostate cancer cells. Tokai Pharmaceuticals is developing galeterone as an oral treatment for castration-resistant prostate cancer. Phase III clinical development of galeterone is underway in the US, Canada, Australia, Western Europe, Spain and the United Kingdom.
