Dr. Ku on Role of Durvalumab in Gastric Cancer

Published: Tuesday, Apr 23, 2019



Geoffrey Y. Ku, MD, medical oncologist, Memorial Sloan Kettering Cancer Center, discusses the role of durvalumab (Imfinzi) in the treatment of patients with gastric cancer.

There remains a lack of clarity on whether PD-L1 inhibitors like durvalumab, atezolizumab (Tecentriq), and avelumab (Bavencio) are comparable with PD-1 inhibitors like pembrolizumab (Keytruda) and nivolumab (Opdivo). These drugs inhibit the same axis, but it is unknown if they have the same activity. Recent studies have looked at PD-L1 inhibition in gastric cancer, particularly with avelumab, but these trials were relatively disappointing, Ku says.

In a 5-cohort study presented at the 2019 AACR Annual Meeting, durvalumab was evaluated as a second- and third-line treatment for patients with gastric cancer. Specifically, researchers were trying to use an interferon-γ signature to enrich patients who were more likely to respond to the therapy. While this biomarker seemed feasible in predicting response to durvalumab, data showed it did not correspond with a significant advantage in terms of clinical outcomes.
