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).

Matthew L. Meyerson, MD, PhD, of the Dana-Farber Cancer Institute, discusses study findings that suggest the variation in frequency of EGFR and KRAS mutations in lung cancer may be associated with genetic ancestry in patients from Latin America. The results indicate it may be possible to identify germline alleles underpinning this link. Finding a germline locus or loci may impact the development of lung cancers with these mutations and may improve lung cancer prevention and screening for populations of Latin American origin, as well as others.

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).

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).

Tina Cascone, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses the findings of the phase II NeoCOAST study, which showed that combination immunotherapy with the anti–PD-L1 monoclonal antibody durvalumab and other novel agents resulted in numerically higher major pathologic response rates than durvalumab alone in the neoadjuvant setting for patients with early-stage resectable non–small cell lung cancer. Translational results also supported combination therapies over single-agent therapy (Abstract CT011).

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).
