Tumor cell-expressed OX40L enhances the efficacy of PD-1 axis blockade in non-small cell lung cancer

Background
Immune checkpoint inhibitors have transformed non-small cell lung cancer (NSCLC) treatment. Understanding the tumor-immune interactions that dictate sensitivity to PD-1 blockade is essential for improving outcomes and optimizing immunothera…

Neoadjuvant chemoimmunotherapy with afatinib for locally advanced head and neck squamous cell carcinoma (neoCHANCE-2): an open-label, single-arm, phase 2 study

Background
While immune checkpoint inhibitor-based neoadjuvant therapy shows promise in locally advanced head and neck squamous cell carcinoma (LA-HNSCC), the optimal regimen has yet to be established. We report, for the first time, a neoadjuvant trea…

PRKX-mediated stabilization of PD-L1 characterizes an immunosuppressive gastric cancer subtype

Background
Gastric cancer (GC) derives limited benefit from immunotherapy, with clinical responses observed in only a minority of patients. Increasing evidence suggests that heterogeneity within the tumor immune microenvironment (TME) is a critical de…

HIF1A+CSF3R+ neutrophils-dominated hypoxic niche induced metabolic reprogramming for neoadjuvant therapy resistance in NSCLC

Background
Non-small cell lung cancer (NSCLC) is one of the frequently occurring cancers characterized by molecular heterogeneity and multiple immune cell infiltration patterns, which are associated with treatment sensitivity and resistance. However, …

Camrelizumab plus nimotuzumab as second-line therapy for advanced esophageal squamous cell carcinoma: a multicenter phase II study

Background
Therapeutic options for advanced esophageal squamous cell carcinoma (ESCC) after first-line failure remain limited, particularly in patients previously exposed to immune checkpoint inhibitors (ICIs). We evaluated the efficacy, safety, and e…

Anti-CMV IgG titer determines organ-specific protection toward immune checkpoint blockade-induced toxicities

Background
Immune-related adverse events (irAEs) post-immune checkpoint blockade (ICB) are a leading cause of patient morbidity. Robust peripheral biomarkers of irAEs are required to improve patient stratification to existing treatment regimens, and t…

TAMing the tumor: targeting immune inhibitory receptors on tumor-associated macrophages in pediatric brain tumors – an emerging immunotherapy strategy

Brain tumors are the most common solid tumors in children. Despite recent advancements in cancer survival, the prognosis for high-grade pediatric brain tumors remains poor, with treatments resulting in severe long-term side effects. Over the last deca…

Transcriptomic analysis of a phase 1 trial for intraperitoneal monocytes plus IFNs in ovarian cancer reveals support and recruitment of cell-mediated immunity

Background
Ovarian cancer is the most lethal gynecological malignancy and lacks therapeutic options in the recurrent setting. We previously determined the safety and initial clinical activity of intraperitoneal autologous monocytes with interferon gam…

Phase 1/1b open-label, first-in-human study of HER2xCD3xCD28 trispecific T-cell engager (SAR443216) in participants with R/R HER2-expressing solid tumors

Background
SAR443216 is an engineered human trispecific antibody that targets human epidermal growth factor receptor 2 (HER2)-positive (HER2+) cancer cells and activates T cells via co-engagement of cluster of differentiation (CD)3 and CD28. This firs…

Anti-CTLA-4 antibody potentiates the antitumor effect of armed oncolytic virus OVM18 via enhancing intratumoral IL-18R1+CD8+ T cells

Background
Oncolytic virus M1 encoding a mutant IL-18 decoy (OVM18) represents a novel virotherapy that integrates selective oncolysis with localized activation of the IL-18 pathway. However, the heterogeneity of therapeutic responses suggests that ho…
