The Cancer Epigenetics Society has continued expanding its cancer epigenetic drug clinical trial repository which now covers 500+ clinical trials. These include most if not all reported completed, ongoing, and recruiting cancer clinical trials on DNA methyltransferases (DNMTi), histone deacetylases (HDACi), histone methyltransferases (HMTi), and histone demethylases (KDMi). All databases are currently freely accessible to all users, with no login or registration required. The database may be accessed directly at https://ces.b2sg.org/cedd/ (Cancer Epigenetics Society news; August 17, 2016).
