Cathy Eng, MD, on Colorectal Cancer: FOLFOXIRI, Cetuximab, and Bevacizumab as First-Line Treatment
2021 ASCO Annual Meeting
Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, discusses two abstracts from a session she co-chaired: the phase II DEEPER trial, which explored the use of FOLFOXIRI plus cetuximab vs FOLFOXIRI plus bevacizumab as first-line treatment in metastatic colorectal cancer with RAS wild-type tumors; and the phase II FIRE-4.5 study, which investigated FOLFOXIRI plus either bevacizumab or cetuximab as first-line treatment of BRAF V600E–mutant advanced disease (Abstracts 3501 and 3502).

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).

Matt D. Galsky, MD, of the Tisch Cancer Institute at Icahn School of Medicine at Mount Sinai, discusses results from a phase II trial designed to test gemcitabine and cisplatin plus nivolumab as neoadjuvant therapy in patients with muscle-invasive bladder cancer and to better predict benefit in those who opted out of cystectomy (Abstract 4503).

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).

Ian Chau, MD, of Royal Marsden NHS Foundation Trust, discusses first results of the CheckMate 648 study, which showed that nivolumab plus chemotherapy and nivolumab plus ipilimumab both demonstrated superior overall survival vs chemotherapy alone in patients with advanced esophageal squamous cell carcinoma. These regimens may represent potential new first-line treatment options (Abstract 4001).

Karim Fizazi, MD, PhD, of Institut Gustave Roussy, discusses first results from the phase III PEACE1 trial, which showed that abiraterone plus androgen-deprivation therapy and docetaxel improves radiographic progression-free survival in men with de novo metastatic prostate cancer (Abstract 5000).
