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).

Lillian L. Siu, MD, of Canada’s Princess Margaret Cancer Centre, discusses biomarker-driven precision cancer medicine, the optimal sequencing of immunotherapy (IO) with standard treatments in curative settings, IO targets beyond PD-1/PD-L1 and combinatorial strategies, and next-generation adoptive cell therapies (Abstract PL06).
The ASCO Post Staff
Josh Neman, PhD, of the Keck School of Medicine, University of Southern California, discusses the distribution of brain metastasis to preferential brain regions that vary according to cancer subtype, how neurotransmitters respond, and the ways in which the central nervous system acclimates (Abstract SY32).
The ASCO Post Staff
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).
The ASCO Post Staff
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).
The ASCO Post Staff
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).
