Sampling MethodProbability Sample
Study Population

Patients with histologically confirmed HR-positive, HER2-negative breast cancer treated with abemaciclib in combination with endocrine therapy or as a single agent

You may qualify if:

  • Age ≥18 years
  • Patients must have a diagnosis of HR+ breast cancer. To fulfill the requirement of HR+ disease, a breast cancer must express, by immunohistochemistry (IHC), at least one of the hormone receptors (ER, progesterone receptor \[PgR\]) as defined in the relevant American Society of Clinical Oncology/College of American Pathologists Guidelines: For ER and PgR assays to be considered positive, ≥1% of tumor cell nuclei must be immunoreactive by immunohistochemistry (IHC)
  • Patient has HER2-negative breast cancer defined as a negative in situ hybridization test or an IHC status of 0, 1+ or 2+. If IHC is 2+, a negative in situ hybridization (FISH, CISH, or SISH) test is required by local laboratory testing.
  • Patients with advanced (loco-regionally recurrent, or metastatic) breast cancer not amenable to curative therapy.
  • WHO performance status of 0-2
  • The patient has adequate organ function
  • Any number of prior therapies (including none) is permitted
  • Рatients who will start Abemaciclib as a Single Agent or in combination with endocrine therapy

You may not qualify if:

  • Uncontrolled intercurrent illness including, but not limited to, known ongoing or active infection, including HIV, active hepatitis B or C, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia (specifically, atrial fibrillation or ventricular dysrhythmias except ventricular premature contractions), or psychiatric illness/social situations that would limit compliance with study requirements.
  • Participants must not be pregnant or breastfeeding
