Pasi A. Janne, MD, PhD, on NSCLC: Patritumab Deruxtecan to Target HER3
2021 ASCO Annual Meeting
Pasi A. Janne, MD, PhD, of Dana-Farber Cancer Institute, discusses study findings that show patritumab deruxtecan is effective in patients with EGFR-mutated and inhibitor-resistant non–small cell lung cancer. Dr. Janne also explains why targeting HER3, a mutation expressed in most EGFR-altered cancers, is a beneficial treatment approach (Abstract 9007).
Melinda L. Telli, MD, of Stanford University, discusses results of a phase II study on neoadjuvant talazoparib in germline BRCA1/2 mutation–positive, early HER2-negative breast cancer. In this setting, talazoparib monotherapy was active and yielded pathologic complete response rates comparable to those observed with combination anthracycline and taxane-based chemotherapy regimens (Abstract 505).
Byoung Chul Cho, MD, PhD, of the Yonsei Cancer Center, discusses study results that showed treatment with the EGFR-MET bispecific antibody amivantamab plus the EGFR inhibitor lazertinib yielded responses in 36% of chemotherapy-naive patients with non–small cell lung cancer whose disease progressed on osimertinib. Genetic biomarkers may be able to identify patients most likely to benefit from the combination regimen (Abstract 9006).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses first phase III results from a prospective high-risk cohort of patients with luminal breast cancer, which showed a good prognosis in some women with more than four positive lymph nodes and low recurrence scores. The study also showed that a lower postendocrine Ki67 index and limited tumor burden may be promising criteria for chemotherapy de-escalation strategies, even in patients with high recurrence scores (Abstract 504).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses results from the ADAPT HR–/HER2+ trial, which showed, for the first time, improved pathologic complete response and survival in patients with early breast cancer who were treated weekly with a de-escalated 12-week regimen of neoadjuvant paclitaxel plus pertuzumab and trastuzumab (Abstract 503).
Debora S. Bruno, MD, of Seidman Cancer Center at Cleveland Medical Center, discusses study findings that show Black patients with advanced or metastatic non–small cell lung cancer tend to be less likely to undergo biomarker testing or to be treated in clinical trials than White patients. Recommended broad-based testing, says Dr. Bruno, may help ensure equal access to quality care and clinical trials (Abstract 9005).
