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).

Gautam Mehta, MD, of the U.S. Food and Drug Administration, discusses how accelerated approval of potentially life-saving cancer therapies has been applied in precision oncology. Although “fast-tracking” drugs presents opportunities and challenges, one possible measure of the program’s success is the fact that, to date, no solid tumor accelerated-approval indications have been withdrawn (Abstract DC06).

Priscilla K. Brastianos, MD, of Harvard Medical School and Massachusetts General Hospital, talks about her efforts to better understand how brain metastases evolve genomically and to test such agents as abemaciclib, paxalisib, and entrectinib, which may stop their growth. Palbociclib, a CDK inhibitor, has already shown potential benefit. A national cooperative group trial is underway in multiple centers to identify novel treatments for patients with brain metastases, who typically have a poor prognosis (Abstract SY38).

Zev Wainberg, MD, of the University of California, Los Angeles Medical Center, discusses preliminary data on the safety and efficacy of TTX-030, an anti-CD39 antibody, in combination with budigalimab and FOLFOX for the first-line treatment of locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma. The study suggests the regimen may prove to be of benefit as a first-line treatment, regardless of combined positive score status (Abstract CT015).

Charles L. Sawyers, MD, of Memorial Sloan Kettering Cancer Center, discusses the battle against treatment resistance and how to overcome it, as well as the power of observational clinical data in precision oncology, derived largely from his experience with Project GENIE, and the role of genetic ancestry (Abstract PL02).

Meenakshi Anurag, PhD, of Baylor College of Medicine, discusses results from the ALTERNATE trial, which showed the combination of anastrozole plus fulvestrant was superior to either drug alone in inhibiting tumor proliferation in postmenopausal women with early-stage luminal B breast cancer (Abstract CT026).
