During a debate at the Gastrointestinal Cancers Symposium, Florian Lordick, MD, argued that knowledge of PD-L1 expression level was needed before starting immune checkpoint inhibitor therapy. He was challenged by Aaron James Scott, MD, who argued that knowledge of PD-L1 is not necessary before initiating immune checkpoint inhibitor therapy.

In an interview with Targeted Oncology following the tweet chat, Yelena Y. Janjigian, discussed the key takeaways from the discussion and highlighted the biomarkers and standard of care for the patient in this case.

Ryan Sugarman, MD, discusses the design and purpose of the CheckMate 649 trial for gastroesophageal cancers, gastric cancer, and esophageal adenocarcinoma.

In an interview with Targeted Oncology, Ryan Sugarman, MD, discussed the CheckMate 649 trial and Q-TWiST results to provide a further understanding of survival and quality of life benefit of nivolumab plus chemo versus chemo alone.

Findings show DKN-01, tislelizumab, and capecitabine/oxaliplatin (CAPOX) combination to be well tolerated and have encouraging clinical activity as frontline treatment of patients with advanced gastroesophageal adenocarcinoma.

In the CheckMate 649 trial, durable survival benefit was achieved with Nivolumab plus chemotherapy in patients with gastric or gastroesophageal junction cancer.

Results from the phase 3 KEYNOTE-062 study appear mixed for both pembrolizumab monotherapy versus chemotherapy and pembrolizumab plus chemotherapy versus chemotherapy alone in patients with advanced gastric or gastroesophageal junction adenocarcinoma.

Results presented during the 2022 Gastrointestinal Cancers Symposium showed that 58.6% of evaluable patients experienced complete regression and fibrosis with no tumor cells.

Data from the phase 3 CheckMate-649 trial showed that the combination therapy of nivolumab and chemotherapy showed a sustained survival benefit in patients with advanced gastric, gastroesophageal junction (GEJ), or esophageal cancer, in contrast to the combination of nivolumab and ipilimumab.

The combination of nivolumab/ipilimumab did not significantly improve OS compared with chemotherapy in patients with advanced gastric, gastroesophageal junction, or esophageal cancer.
