Luca Gianni, MD, on Locally Advanced, HER2-Positive Breast Cancer: New Data on Neoadjuvant Therapy and Atezolizumab
2023 SABCS
Luca Gianni, MD, of Milan’s Fondazione Michelangelo, discusses findings from the APTneo Michelangelo trial, which showed that adding atezolizumab to chemotherapy and trastuzumab plus pertuzumab did not significantly increase the rate of pathologic complete response (pCR) in women with HER2-positive breast cancer. An exploratory analysis showed that adding atezolizumab to neoadjuvant anthracycline and cyclophosphamide followed by HPCT (trastuzumab + pertuzumab and chemotherapy) led to higher pCR rates than HPCT and atezolizumab (Abstract LBO1-02).

Sherene Loi, MD, PhD, of Australia’s Peter McCallum Cancer Centre, discusses an exploratory analysis of CheckMate 7FL which showed that patients with PD-L1–positive, high-risk, estrogen receptor–positive, HER2-negative primary breast cancer may achieve substantial pathologic complete response rates with the addition of nivolumab to neoadjuvant chemotherapy (Abstract GS01-01).

Hope S. Rugo, MD, of the University of California, San Francisco Helen Diller Family Comprehensive Cancer Center, discusses patient-reported outcomes from the phase III CAPItello-291 study; the trial centered on adding capivasertib to fulvestrant in patients with aromatase inhibitor–resistant, hormone receptor–positive, HER2-negative advanced breast cancer. Patients treated with capivasertib and fulvestrant reported maintained health-related quality of life longer than those treated with placebo and fulvestrant (Abstract PS02-02).

Cynthia X. Ma, MD, PhD, of Washington University School of Medicine in St. Louis, discusses phase I findings showing the safety and tolerability of copanlisib and fulvestrant in combination with continuous or intermittent abemaciclib in patients with estrogen receptor–positive, HER2-negative metastatic breast cancer. Preliminary antitumor activity, which was observed, will be further examined in the phase II trial (ClinicalTrials.gov identifier NCT03939897) (Abstract PS17-06).

Barbara Pistilli, MD, of France’s Gustave Roussy, discusses a phase Ib analysis from the CAPItello-292 study, which showed capivasertib plus palbociclib plus fulvestrant was tolerable at all dose levels in heavily pretreated patients with hormone receptor–positive, HER2-negative advanced breast cancer. As data collection continues, evidence of clinical activity has been observed in patients treated with the recommended phase III dose (Abstract PS12-09).

Hope S. Rugo, MD, of the University of California, San Francisco Helen Diller Family Comprehensive Cancer Center, discusses data from the phase II KEYLYNK-009 study, which compared pembrolizumab plus olaparib vs pembrolizumab plus chemotherapy after induction with pembrolizumab plus chemotherapy for patients with locally recurrent inoperable or metastatic triple-negative breast cancer (Abstract GS01-05).
