“With demonstration of efficacy in biomarker-selected BRCA-like phenotype triple-negative breast cancer, the results of this trial are a very positive step toward expanding the role of PARP inhibitors beyond germline BRCA in breast cancer."
Javier Cortes, MD, PhD, discusses the data from the phase 3 KEYNOTE-355 trial of pembrolizumab and chemotherapy versus placebo and chemotherapy for previously untreated patients with locally recurrent inoperable or metastatic triple-negative breast cancer.
"We are disappointed [with] this outcome. Breast cancer is a leading cause of death around the world and delaying or preventing the development of metastatic disease is a significant unmet need. PALLAS is a large study with many subgroups and we are actively collaborating to determine if there are patients who may benefit from adjuvant treatment with the palbociclib combination."
"Pembrolizumab and chemotherapy demonstrated a statistically significant and clinically meaningful improvement in PFS as compared with chemotherapy alone for the first-line treatment of metastatic TNBC with a PD-L1 CPS of 10 or higher tumors."
The addition of tucatinib to treatment with trastuzumab and capecitabine resulted in more than a 60% reduction in the risk of central nervous system progression or death in both patients with previously treated HER2-positive metastatic breast cancer who have active or stable brain metastases.
“Preliminary data for the 18 patients who have received belantamab mafodotin 2.5 mg/kg single dosing with bortezomib/dexamethasone suggests that this combination has an acceptable safety profile with no new safety signals identified."
"Based on the results of our study, women who present with a new diagnosis of breast cancer already in stage IV should not be offered surgery and radiation for the primary breast tumor with the expectation of a survival benefit."
In an interview with Targeted Oncology following the announcement of sacituzumab govitecan accelerated FDA approval, Hope Rugo, MD, discussed the published data from the phase 1/2 basket trial and the relevance of having sacituzumab govitecan available for the treatment of patients with metastatic triple negative breast cancer.
