Randomized Phase II Study to Assess PD 0332991 in Breast Cancer

Summary

This is a Phase II study trying to identify whether short term treatment with PD0332991 yields anti-proliferative response -defined by a low level of Ki67 expression (IHC) at surgery- or induces senescence as determined by SABG expression (IHC) in tumors from patients with early breast cancer non-candidates for neoadjuvant hormonotherapy or chemotherapy, as compared to no treatment.
