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).

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).

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).

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).

Marcia R. Cruz-Correa, MD, PhD, of the University of Puerto Rico Comprehensive Cancer Center, discusses a way to possibly transform cancer outcomes by teaming up basic scientists, clinical researchers, and community advocates to work together, decode the complexity of cancer, and find points at which to intervene in the development of tumor cells. One strong focus is on communities disproportionately affected based on their genomic ancestry, geographic location, and ethnicity (Abstract PL06).

Nicolas Girard, MD, PhD, of the Institut Curie, discusses findings from the phase III CheckMate 816 trial, which is the first study with an immunotherapy-based combination to demonstrate improved event-free survival and pathologic complete response in the neoadjuvant setting for patients with resectable stage IB to IIIA non–small cell lung cancer. The results may benefit the 30% to 55% of patients whose cancer recurs after surgery (Abstract CT012).
