Spots Global Cancer Trial Database for Phase 2 Study of Fulvestrant With and Without Entinostat in Postmenopausal Women With ER+ Advanced Breast Cancer

Study Description

Brief Summary: Preclinical data has demonstrated that entinostat (SNDX-275) can enhance fulvestrant sensitivity in hormone receptor-positive breast cancer in animal models. The addition of entinostat to fulvestrant will provide clinical benefit to patients with locally advanced or metastatic breast when compared to fulvestrant plus placebo. Also, based on previous data, patients exposed to entinostat who demonstrate an elevated level of protein lysine acetylation will have an improved efficacy outcome.

Detailed Description: Entinostat (SNDX-275) inhibits mechanisms of resistance to hormone therapy in breast cancer (BC) cells, thereby prolonging sensitivity of the cells to fulvestrant. Preclinical data has demonstrated that entinostat can enhance fulvestrant sensitivity in hormone receptor-positive BC in animal models. Thus, it is hypothesized that the addition of entinostat to fulvestrant will provide clinical benefit to patients with locally advanced or metastatic BC when compared to fulvestrant plus placebo. Preliminary data from Phase 2 Study SNDX-275-0301 suggest patients with higher levels of protein lysine acetylation who receive entinostat with exemestane potentially have improved clinical outcomes (e.g., PFS, OS) when compared to patients with lower levels of protein lysine acetylation. Thus, it is hypothesized that patients exposed to entinostat and who demonstrate an elevated level of protein lysine acetylation will have an improved efficacy outcome.
