NCT00828854

Summary

The addition of entinostat to an AI will result in a maximal abrogation of estrogen receptor-α mediated activity and inhibit mechanisms of resistance to the aromatase inhibitor. It is hypothesized that entinostat with continued AI will increase the estimated AI clinical benefit rate (CBR) from 5% to 25% with an acceptable safety profile.
