An evaluation of palbociclib as a breast cancer treatment option: a current update. Expert Opin Pharmacother. 2020 Nov 16;:1-10 Authors: Gallanis GT, Pericas RI, Riegel AT, Pohlmann PR Abstract INTRODUCTION: Patients with hormone receptor-positive/HER2-negative (HR+/HER2-) metastatic breast cancer have benefitted from treatment with palbociclib, a cyclin-dependent kinase (CDK) 4/6 inhibitor capable of selectively targeting mechanisms of cell cycle progression that contribute to tumor cell proliferation. Palbociclib use in this setting demonstrates improved progression-free survival when given in combination with aromatase inhibitors or fulvestrant. AREAS COVERED: The authors describe the current state of research surrounding palbociclib use in breast cancer, present evidence supporting a role for palbociclib in additional subtypes of metastatic breast cancer such as HER2-positive (HER2+) and triple-negative, report ongoing clinical trials aimed at expanding the scope of use for palbociclib, and discuss expected clinical results that will better inform decisions on including palbociclib as a part of breast cancer treatment strategies. EXPERT OPINION: Preclinical and clinical studies have shown promising evidence for palbociclib use in metastatic HER2+ and androgen receptor-expressing triple-negative breast cancer but mixed results in the adjuvant/neoadjuvant setting, where differences may only be detectable in high-ri...
