Tanios S. Bekaii-Saab, MD, on Pancreatic and Other Tumors With KRAS G12C Mutation: Updated Data on Use of Adagrasib
2022 ASCO Gastrointestinal Cancers Symposium
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).

Anthony B. El-Khoueiry, MD, of the University of Southern California, Norris Comprehensive Cancer Center, discusses two key phase III studies of first-line treatment in hepatocellular carcinoma: the LAUNCH trial, which explored lenvatinib combined with transarterial chemoembolization for advanced disease; and the HIMALAYA trial, which studied tremelimumab and durvalumab for unresectable disease. The latter trial may represent a new standard of care, according to Dr. El-Khoueiry.

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).

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).

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).

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).
