Sarah Sammons։ Does the Endocrine Backbone Matter with CDK4/6 Inhibitors?

Sarah Sammons, Breast Medical Oncologist and Senior Physician at Dana-Farber’s Breast Oncology Center, shared a post by Liam Harris on X, adding:

“Trying to reconcile adjuvant success with first line failure.

Is it that when CDK4/6 inhibition dominates the treatment effect in endocrine-sensitive disease, swapping the endocrine backbone doesn’t meaningfully change outcomes? Would Lidera have been negative if CDK 4/6 was added?”

Quoting Liam Harris on X:

“Mechanism looks promising on paper, but clinical validation tells a different story.

Waiting on SERENA-4 to see if the class delivers.”
