Summary
Brief summary
This is a prospective, two arm, international, multicenter, randomized, open-label Phase III
study evaluating the addition of 2 years of palbociclib to standard adjuvant endocrine
therapy for patients with HR+ / HER2- early breast cancer (EBC).

The purpose of the PALLAS study is to determine whether the addition of palbociclib to
adjuvant endocrine therapy will improve outcomes over endocrine therapy alone for HR+/HER2-
early breast cancer. Assessment of a variety of correlative analysis, including evaluation of
the effect of palbociclib in genomically defined tumor subgroups, is planned.
