Breast Cancer – Current Treatment – Current Treatment: Physician Insights – Breast Cancer (US)
The breast cancer treatment landscape is rapidly evolving. CDK4/6 inhibitors (Pfizer’s Ibrance, Novartis’s Kisqali, and Eli Lilly’s Verzenio) plus endocrine therapy are entrenched first-line treatments for metastatic HR-positive / HER2-negative disease; this drug class moved to the early-stage setting with the approval of adjuvant Verzenio in 2021. Biomarker-driven therapies—including Menarini Group’s Orserdu (ESR1-mutant), Novartis’s Piqray (PIK3CA-mutant), and AstraZeneca’s Truqap (PIK3CA/AKT1/PTEN-mutant)—have expanded treatment options for metastatic HR-positive / HER2-negative disease. Meanwhile, Merck & Co.’s Keytruda has changed the treatment paradigm for certain patients with early and metastatic triple-negative breast cancer. PARP inhibitors (AstraZeneca / Merck & Co.’s Lynparza, Pfizer’s Talzenna) are an option for PARP-mutant patients with either triple-negative or HR-positive / HER2-negative disease; for these two subtypes, the approval of next-generation ADCs (Gilead’s Trodelvy, Daiichi Sankyo / AstraZeneca’s Enhertu for HER2-low) has diversified therapy options for metastatic patients. In the HER2-positive metastatic setting, Enhertu´s label expansion to the second line is redefining treatment.
QUESTIONS ANSWERED
- What are the treatment rates for breast cancer by key subtype and line of therapy?
- What are physician-reported testing rates for select biomarkers (e.g., mutations in PIK3CA, ESR1, and PARP; HER2-low and PD-L1 expression) in relevant breast cancer subtypes?
- What is the patient share of key drugs and regimens by type of breast cancer?
- What are the main drivers of and key obstacles to the uptake of select therapies?
