Abemaciclib Is Effective in Palbociclib-Resistant Hormone Receptor–Positive Metastatic Breast Cancers

Published date:
09/11/2023
Excerpt:
Finally, data from a cohort of 52 patients indicated that patients with HR-positive/HER2-negative MBC who progressed on palbociclib-containing regimens can exhibit a meaningful overall clinical benefit from abemaciclib-based therapy when administered after palbociclib. These findings provide the rationale for clinical trials evaluating the benefit of abemaciclib treatment following progression on a prior CDK4/6i.
