Pfizer provides update on Phase III PALLAS trial of Ibrance + endocrine therapy in HR+, HER 2- early breast cancer.

As announced by the Austrian Breast & Colorectal Cancer Study Group and the Alliance Foundation Trials, LLC, Pfizer Inc. reports that following a preplanned efficacy and futility analysis, the independent Data Monitoring Committee (DMC) of the collaborative Phase III early breast cancer PALbociclib CoLlaborative Adjuvant Study (PALLAS) determined that the trial is unlikely to show a statistically significant improvement in the primary endpoint of invasive disease-free survival (iDFS)

. Patients currently receiving palbociclib in the study will be advised about next steps by their physicians and long-term follow up of all patients will proceed as planned. No unexpected new safety signals were observed in patients receiving palbociclib.The PALLAS trial compares palbociclib plus standard adjuvant endocrine therapy to standard adjuvant endocrine therapy alone in women and men with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) early (stage 2 and 3) breast cancer and is an academically-led global collaboration, involving more than 400 centers in 21 countries around the globe.
