Who may be able to join

  • Women who have gone through menopause (as defined by NCCN guidelines), are aged 18 or older, and have estrogen receptor-positive (ER+) breast cancer that has spread to other parts of the body or has come back locally in a way that cannot be treated with a goal of cure.
  • People whose cancer has previously been treated with a specific type of drug called a CDK4/6 inhibitor (specifically palbociclib, ribociclib, or abemaciclib), either on its own or combined with a hormone-based therapy, for advanced disease.
  • People who have had up to 3 lines of treatment after their CDK4/6 inhibitor, any number of prior hormone-based treatments, and up to 1 prior chemotherapy course.
  • People whose cancer has been confirmed as ER+ through a tissue sample (biopsy) taken from a site of advanced or returning disease — with some exceptions for people with bone-dominant cancer or cases where a safe biopsy cannot easily be obtained, where the original cancer diagnosis may be used instead.
  • People whose cancer tests positive for estrogen receptors in at least 1% of cancer cells on a standard lab test.
  • People whose cancer is confirmed to not have high levels of a protein called HER2 (based on standard laboratory testing methods).
  • People whose tumor or blood sample has been tested for specific genetic changes in a certified laboratory after their cancer stopped responding to a CDK4/6 inhibitor — or people who are willing to have this testing done as part of the study.
  • People who have stored (archived) tumor tissue available that can be used for research, ideally enough to produce at least 10 thin tissue sections.
  • People who have had standard imaging scans to assess the extent of their cancer (such as a PET/CT scan, or a CT scan with contrast plus a bone scan).
  • People who are willing and able to give written informed consent to take part in the study.

Who may not be able to join

Each point below is a reason the trial team may not be able to accept someone. It is not a list of requirements to meet.

  • People whose most recent or current treatment includes abemaciclib.
  • People who are currently receiving other cancer treatments, with the exception of bone-strengthening medications such as bisphosphonates or denosumab.
  • People who have taken part in another experimental cancer treatment study within the past 3 weeks.
  • People who have a known brain or central nervous system involvement from their cancer that has not been treated, unless it has been clinically stable for at least 3 months.
