Romain Cohen, MD, PhD, on Metastatic Colorectal Cancer: Long-Term Follow-up on Nivolumab Plus Ipilimumab
2022 ASCO Gastrointestinal Cancers Symposium
Romain Cohen, MD, PhD, of Sorbonne University and Saint-Antoine Hospital, discusses phase II results of the GERCOR NIPICOL study, which suggests nivolumab plus ipilimumab at a fixed duration of 1 year continued to show durable activity in patients with chemoresistant microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer after 3 years of follow-up. Dr. Cohen points out there is now some question as to whether all patients need 2 years of therapy (Abstract 13).

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.

Van K. Morris, MD, of The University of Texas MD Anderson Cancer Center, discusses phase I/II data suggesting that encorafenib plus cetuximab and nivolumab is safe and well tolerated for patients with microsatellite-stable BRAF V600E–mutated metastatic colorectal cancer (Abstract 12).

Tanios S. Bekaii-Saab, MD, of Mayo Clinic, discusses new findings from the KRYSTAL-1 study, which suggested adagrasib monotherapy is well tolerated and demonstrates clinical activity in pretreated patients with unresectable or metastatic pancreatic cancer or other gastrointestinal tumors harboring a KRAS G12C mutation. Adagrasib is an inhibitor of the KRAS G12C mutation (Abstract 519).

Zev A. Wainberg, MD, of the University of California, Los Angeles, discusses an update, of 25 additional months, on phase III safety and efficacy results from the KEYNOTE-062 trial. This study compared pembrolizumab with or without chemotherapy vs chemotherapy alone for patients with PD-L1–positive advanced gastric or gastroesophageal junction adenocarcinoma (Abstract 243).

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.
