David A. Barbie, MD, on Mesothelioma: Activating the STING Pathway May Promote Antitumor Immunity
AACR Annual Meeting 2022
David A. Barbie, MD, of Dana-Farber Cancer Institute, discusses his laboratory’s studies, showing that malignant pleural mesothelioma, an inflamed cancer type with marginal response to immune checkpoint blockade, demonstrated high tumor cell STING expression and response to STING agonists in combination with natural killer cell therapies ex vivo. STING is the tumor cell stimulator of interferon genes (Abstract 4168).

Christine A. Iacobuzio-Donahue, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses her research on the evolutionary features of advanced stage pancreatic cancers and the insights that may be used to help improve patient outcomes (Abstract PL05).

Ari M. VanderWalde, MD, MPH, MBioeth, of The West Clinic, discusses results from the S1616 trial involving patients with metastatic or unresectable melanoma who had primary resistance to PD-1 or PD-L1 inhibitors. Compared with ipilimumab alone, the combination of ipilimumab plus nivolumab benefited some patients: those with tumors that responded to therapy showed an increased amount of CD8+ cells. Because there is no standard treatment for metastatic melanoma after failure of PD-1 inhibitors in BRAF wild-type disease, this research may provide a viable option in the future (Abstract CT013).

Benoit You, MD, PhD, of the Lyon University Hospital (France), discusses phase I/II safety and efficacy results from the ENDOLA trial that combined olaparib with metronomic cyclophosphamide and metformin in patients with advanced pretreated endometrial cancer. At 10 weeks, the non–disease progression rate was 61.5%, reaching the primary endpoint of the study. Median progression-free survival was 5.1 months. Research on biomarkers of efficacy is ongoing (Abstract CT005).

Yaqi Zhao, MSc, of St. Jude Children’s Research Hospital, discusses findings from the phase III INO-VATE trial, which showed that inotuzumab ozogamicin reduced the signs and symptoms of acute lymphoblastic leukemia associated with a variety of gene and chromosome changes. Future studies may confirm which patients are more likely to benefit from this agent (Abstract CT027).

Klaus Pantel, MD, of the University Medical Center Hamburg-Eppendorf, discusses liquid biopsy technologies and biomarkers, with a focus on circulating tumor cells and circulating tumor DNA; clinical applications such as early detection of cancer, improved staging, and surveillance of measurable residual disease; and how best to detect and monitor response to systemic therapies, as well as ways to identify therapeutic targets and resistance mechanisms (Abstract SY08).
