Javier Cortés, MD, PhD, on Previously Untreated Triple-Negative Breast Cancer: Pembrolizumab Plus Chemotherapy
2021 San Antonio Breast Cancer Symposium
Javier Cortés, MD, PhD, of the International Breast Cancer Center, discusses the final phase III results of KEYNOTE-355, which showed that pembrolizumab and chemotherapy improved overall and progression-free survival, compared with placebo and chemotherapy, for patients with previously untreated, locally recurrent, inoperable or metastatic triple-negative breast cancer (Abstract GS1-02 ).

Michael Gnant, MD, of the Medical University of Vienna, discusses phase III findings from the PALLAS study, which showed that adding 2 years of palbociclib to ongoing adjuvant endocrine therapy did not improve survival for patients with stage II to III hormone receptor–positive, HER2-negative early breast cancer. Dr. Gnant also talks about whether any correlative studies hint at patient subgroups that this regimen may benefit (Abstract GS1-07) .

Charles Coombes, MD, PhD, of Imperial College, London, discusses study results on samuraciclib, a first-in-class, oral, selective inhibitor of CDK7, in combination with fulvestrant in patients with advanced hormone receptor–positive HER2-negative breast cancer. The combination of agents has demonstrated evidence of anti-tumor activity for patients who have progressed on their prior CDK4/6 inhibitor treatment (Abstract GS3-10).

François-Clément Bidard, MD, PhD, of the Institut Curie, discusses phase III findings of the PADA-1 study, which showed that optimizing endocrine therapy after detecting the ESR1 mutation in patients with hormone receptor–positive, HER2-negative metastatic breast cancer may double their median progression-free survival (Abstract GS3-05).

Peter Schmid, MD, PhD, of Barts Cancer Institute, discusses phase III findings from KEYNOTE-522, in which researchers found a generally consistent event-free survival benefit among patients with early-stage high-risk triple-negative breast cancer who were treated with neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab (Abstract GS1-01).

Komal Jhaveri, MD, of Memorial Sloan Kettering Cancer Center, discusses the latest updates from the SUMMIT trial, which explored the combinations of neratinib/fulvestrant/trastuzumab and neratinib plus trastuzumab, as well as fulvestrant alone. The combination regimens appeared to benefit patients with hormone–receptor positive, HER2-mutated metastatic breast cancer who have had prior exposure to CDK4/6 inhibitors, and those with HER2-mutated triple-negative disease (Abstract GS4-10).
