Chau T. Dang, MD, the Regional Care Network Medical Site Director at Memorial Sloan Kettering Westchester, discusses the safety profile of pertuzumab (Perjeta) plus trastuzumab (Herceptin) in patients with HER2-positive locally advanced, inflammatory, or early-stage breast cancer.
The 5-year results from the final analysis of the phase 2 BERENICE trial (NCT02132949), which were presented during the ESMO Breast Cancer Virtual Meeting 2021, showed that in cohort A of the study, in which patients were treated with standard anthracycline-based chemotherapy followed by pertuzumab/trastuzumab and paclitaxel, incidence of New York Heart Association (NYHA) class III/IV heart failure was 1.5% in the neoadjuvant setting, Dang says.
Additionally, in cohort B, where patients received treatment with 5-fluorouracil/epirubicin/cyclophosphamide followed by docetaxel and pertuzumab/trastuzumab, no incidence of NYHA class III/IV heart failure was reported, Dang notes.
The study followed patients through to the treatment-free follow-up period to report events after the neoadjuvant setting, Dang explains. For cohort A, no additional cardiac events were reported after the neoadjuvant phase, keeping the rate of NYHA class III/IV heart failure at 1.5%. In cohort B, 1 cardiac event was reported in the adjuvant setting, and 1 during the treatment-free follow-up period, which brought the NYHA class III/IV heart failure rate to 1%, Dang concludes.
