Ghassan K. Abou-Alfa, MD, MBA, on Hepatocellular Carcinoma: Open-Label Trial of Tremelimumab and Durvalumab
2022 ASCO Gastrointestinal Cancers Symposium
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).

Thierry André, MD, of Sorbonne University and Saint-Antoine Hospital, discusses phase II results from the GERCOR NEONIPIGA study, which suggests neoadjuvant therapy with nivolumab and ipilimumab may be associated with a high pathologic complete response rate in patients with localized microsatellite instability–high or mismatch repair–deficient esophagogastric adenocarcinoma. This study raises the question of whether surgery could be delayed or avoided for some patients (Abstract 244).

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).

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).

Francesca Battaglin, MD, of USC Norris Comprehensive Cancer Center and the Keck School of Medicine, discusses findings from one of the largest studies to investigate recurrent neoantigens in upper gastrointestinal cancers. Dr. Battaglin and her team identified peptides with high human leukocyte antigen–binding affinity and an association with a positive tumor inflammation signature in both microsatellite-instable and microsite-stable tumors, suggesting a role for such antigens as potential cancer immunotherapy targets (Abstract 246).

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.
