JITC Letter From the Editor - August 2020

Dear JITC Readers,

Welcome to this latest edition of the JITC digest. The papers highlighted this month offer exciting perspectives on the current state of the immunotherapy field as well as promising future directions for research.
Clinical oncologists can find a comprehensive overview of approved and emerging immunotherapies for multiple myeloma, including some of the new CAR T cell therapies currently in development, in the newest clinical practice guideline from SITC, by Nina Shah et al.
Promising clinical data on the use of checkpoint blockade for prostate cancer is provided in an original research article by Julie N Graff et al. The paper is the first to demonstrate durable responses with PD-1 inhibition in a subset of prostate cancer patients.
The identification of biomarkers to predict response to immunotherapy remains an important and ongoing area of study for our field. Two papers in this month’s digest highlight the key role that tumor metabolism plays in determining outcomes after immunotherapy, offering potential biomarkers for future study.
David Chardin and colleagues identify tumor metabolic parameters as measured by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) that are prognostic and predictive for outcomes after anti-PD-1 therapy for non-small cell lung cancer. Another immunometabolic biomarker is identified by Fangming Liu et al, who identify an association between FABP5-positive tumor infiltrating T cells and improved overall and recurrence-free survival in hepatocellular carcinoma.
New immunotherapeutic targets is another high-priority topic for research, and Marta Trüb and colleagues demonstrate promising in vitro anti-tumor properties with a novel fibroblast activation protein (FAP)-targeted 4-1BB agonist (FAP-4-1BBL).
Finally, do not miss an excellent review by Christopher A Chuckran et al of Neuropilin-1, which acts as a receptor ‘hub’ for sorting signals from diverse ligands to both promote regulatory T cell (Treg) stability in the tumor microenvironment and inhibit anti-tumor CD8+ T cell responses—the latest in the Immune Checkpoints Beyond PD-1 review series.
As always, you can also further your reading with highlights from other journals in JITC’s Reading List, selected this month by Claudia M Palena, PhD, of the NCI.
