A range of monoclonal antibodies, including avelumab, atezolizumab, camrelizumab, dostarlimab, durvalumab, sinitilimab, toripalimab, and zimberelimab, have been developed for targeting the interaction between PD-1 and PD-L1. Moreover, the primary focus will be on the underlying mechanism of action as well as the clinical efficacy of bioactive molecules. Current challenges along with the scope of future research directions targeting PD-1/PD-L1 interactions through natural substances are also discussed.
Baseline 68Ga-NOTA-WL12 PET/CT has a potential to predict the pathological response of neoadjuvant immunotherapy combined with chemotherapy in patients with resectable NSCLC, whose efficacy is comparable to that of therapy evaluations employing baseline and follow-up CT and 18F-FDG PET/CT examinations.
In conclusion, toripalimab plus anlotinib is well tolerated and shows promising efficacy in patients with RM-NPC, and ctDNA could be a potential predictive biomarker. The trial is registered at ClinicalTrials.gov (NCT04996758).

This phase Ib/II study evaluated the safety and efficacy of combining toripalimab with the gemcitabine plus nab-paclitaxel (GnP) regimen as first-line treatment for locally advanced or metastatic PDAC and explored predictive biomarkers (ChiCTR2000032293). Importantly, dendritic cells - T helper cells - cytotoxic T lymphocytes (DC-Th-CTL) enriched immune niche and their spatial interactions were dominant predictors of response based on TIME analysis using a cyclic multiplex tissue staining assay, with an area under the curve value of 0.8. Overall, GnP plus toripalimab exhibited good safety and differentiated efficacy in selected population, and the spatial interactions of DC-Th-CTL represent promising predictors to efficacy of immunochemotherapy in locally advanced or metastatic PDAC.
To evaluate the efficacy and safety of toripalimab plus etoposide and platinum-based chemotherapy (EP) vs placebo plus EP as a first-line treatment for patients with ES-SCLC. The treatment exhibited an acceptable safety profile, supporting this combination regimen as a new treatment option for patients with ES-SCLC. ClinicalTrials.gov Identifier: NCT04012606.
