John B.A.G. Haanen, MD, PhD, on Solid Tumors: Early Study Results on CAR T Cells and the CARVac Vaccine Strategy
AACR Annual Meeting 2022
John B.A.G. Haanen, MD, PhD, of the Netherlands Cancer Institute, discusses findings from a phase I study designed to test the safety and efficacy of the CARVac (CAR-T cell-amplifying RNA vaccine) strategy to overcome poor CAR T-cell stimulation and responses in patients with CLDN6-positive advanced solid tumors. Men with testicular cancer in particular showed encouraging responses. Overall, some patients showed long-term CAR T-cell persistence more than 150 days post infusion. Partial responses seemed to deepen further over time (Abstract CT002).

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).

Vivek Subbiah, MD, of The University of Texas MD Anderson Cancer Center, talks about innovative design of clinical studies that may help demonstrate clinical benefit in precision medicine and advance treatment to deliver the right intervention to the right patient at the right time (Abstract DC06).

Patricia M. LoRusso, DO, of the Yale University School of Medicine, discusses how patients may benefit in the coming decade from discoveries about agents that target KRAS, and how important the approval of sotorasib turned out to be, as well as other agents in the research pipeline. Dr. LoRusso also talks about the scientific advances in tackling inhibition (Abstract SY20).

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).

Gulam A. Manji, MD, PhD, of Columbia University Medical Center, discusses phase II results on perioperative combination chemotherapy and pembrolizumab in patients with resectable gastric cancer. The combination appeared to result in many complete pathologic responses (Abstract CT009).
