Heinz-Josef Lenz, MD, on Colorectal Cancer: Update From the CheckMate 9X8 Trial on Nivolumab, mFOLFOX6, and Bevacizumab
2022 ASCO Gastrointestinal Cancers Symposium
Heinz-Josef Lenz, MD, of USC Norris Comprehensive Cancer Center, discusses phase II results from the CheckMate 9X8 study, which compared nivolumab plus fluorouracil/leucovorin/oxaliplatin (mFOLFOX6) and bevacizumab vs mFOLFOX6 and bevacizumab in the first-line treatment of metastatic colorectal cancer. A subgroup of patients may benefit from adding nivolumab to the standard of care in this setting (Abstract 8).

Yu Sunakawa, MD, PhD, of Japan’s St. Marianna University School of Medicine, discusses his findings from the DELIVER trial, which suggest the gut microbiome may predict skin toxicities in patients with advanced gastric cancer who are treated with nivolumab. In addition, some single nucleotide polymorphisms, such as NOTCH1, SEMA4D, NLRC5, and IL-6R genes, may potentially become markers for diarrhea and skin toxicities with this agent.

Nilofer Saba Azad, MD, of Johns Hopkins Sidney Kimmel Cancer Center, assesses the findings from the phase III TOPAZ-1 trial, a study of durvalumab in combination with gemcitabine plus cisplatin in patients with advanced biliary tract cancer. Dr. Azad explains why the study sets a potential new standard of care of gemcitabine plus cisplatin and durvalumab in unselected patients.

Afsaneh Barzi, MD, PhD, of City of Hope Comprehensive Cancer Center and AccessHope, discusses results from a phase I/II study of regorafenib and pembrolizumab in refractory microsatellite-stable colorectal cancer. Although the trial did not meet its primary endpoint, the median overall survival is “provocative,” says Dr. Barzi. An analysis of biomarkers to identify patients with a longer duration of benefit is ongoing (Abstract 15).

Ghassan K. Abou-Alfa, MD, MBA, of Memorial Sloan Kettering Cancer Center and Weill Medical College at Cornell University, discusses phase III results of the HIMALAYA trial, which showed the combination of a single priming dose of tremelimumab added to durvalumab is superior to sorafenib for patients with unresectable hepatocellular carcinoma (Abstract 379).

Kohei Shitara, MD, of Japan’s National Cancer Center Hospital East, discusses a long-term data follow-up from CheckMate 649, which support the continued use of nivolumab plus chemotherapy as first-line treatment in patients with advanced gastric, gastroesophageal junction, and esophageal adenocarcinomas (Abstract 240).
