Trial Outcomes & Findings for A Pharmacodynamics Pre-surgical Study of LEE011 in Early Breast Cancer Patients (MONALEESA-1) (NCT NCT01919229)

NCT ID: NCT01919229

Last Updated: 2016-01-01

Results Overview

Cell cycle response rate is defined by proportion of patients with natural logarithm of Ki-67 levels (expressed as percentage of baseline values) of less than 1 at the time of surgery. Since the trial was prematurely terminated, no statistical analysis was done.
