Hormone receptor (HR)-positive / HER2-negative breast cancer is the most prevalent breast cancer subtype. Treatment decisions are influenced by disease stage, genetic test score, menopausal status, resectability, site of metastasis, and prior treatment received. The FDA approval of three CDK4/6 inhibitors in the metastatic setting (Pfizer’s Ibrance, Novartis’s Kisqali, and Eli Lilly’s Verzenio) has changed physicians’ prescribing behavior and created new dynamics in treatment sequencing. Furthermore, the FDA approvals of two PARP inhibitors (AstraZeneca’s Lynparza and Pfizer’s Talzenna) for metastatic germline BRCA-mutation-positive, HER2-negative (including HR-positive) breast cancer patients, as well as one PI3K inhibitor (Novartis’s Piqray) for advancedPIK3CA-mutation-positive, HR-positive / HER2-negative breast cancer have provided additional treatment options for this patient subgroup.

Questions answered

  • How are HR-positive / HER2-negative patients mapped in terms of menopausal status, risk of recurrence, speed of disease progression, and metastasis site?
  • What are physicians’ standard treatment practices for early-stage and first- to fourth-line therapy for metastatic HR-positive / HER2-negative breast cancer?
  • What are the key drivers and obstacles determining current prescribing for CDK4/6 inhibitors in HR-positive / HER2-negative metastatic breast cancer? How do physicians differentiate between the three CDK4/6 inhibitors?
  • Where do PARP and PI3K inhibitors fit in the treatment algorithm for HR-positive / HER2-negative breast cancer?
