ORLANDO, Fla.--(BUSINESS WIRE)--Concert Pharmaceuticals, Inc. announced today the presentation of data from a preclinical study demonstrating the potential of CTP-347, its novel deuterium-containing serotonin modulator, to avoid the risk of adverse drug-drug interactions when co-administered with tamoxifen, a widely-used breast cancer drug. These data were the subject of a poster presentation at the North American Menopause Society’s 2008 Annual Meeting. Concert is developing CTP-347 as a non-hormonal treatment for vasomotor symptoms (VMS or hot flashes) in patients with increased risk of adverse effects due to, or contraindicated to using, hormone therapy, as well as in the larger menopausal population. CTP-347 is currently in Phase I clinical testing.
