Cadonilimab combined with taxane and cisplatin as the first-line treatment of advanced esophageal squamous cell carcinoma: an open-label, multicenter phase II trial

Background
Cadonilimab, a bispecific antibody simultaneously targeting programmed cell death 1 (PD-1) and cytotoxic T lymphocyte antigen 4, may further boost antitumor activity compared with PD-1 or programmed cell death ligand 1 (PD-L1) inhibitors. H…

PD-L1 directed bispecific V{delta}2-T cell engager combines lysis of PD-L1 expressing tumor cells with PD-1 immune checkpoint inhibition and modulation of the tumor immune microenvironment

Background
Despite the notable success of programmed death ligand 1 (PD-L1)/programmed death 1 (PD-1) immune checkpoint blockade in cancer, resistance remains a substantial challenge. Combining immune checkpoint blockade with direct targeting of effec…

Targeting PD-L1-CMTM6 interactions in myeloid cells triggers PD-L1 degradation and enhances cytotoxic T-cell expansion

Background
Immune checkpoint therapies targeting programmed cell death protein 1 (PD-1) and programmed death ligand 1 (PD-L1) have been met with limited clinical responses in the treatment of patients of varying cancer types. Current US Food and Drug …

Bi-specific T cell-engaging antibody triggers protective immune memory and glioma microenvironment remodeling in immune-competent preclinical models

Background
Bispecific T cell-engagers (BTEs) are engineered antibodies that redirect T cells to target antigen-expressing tumors. BTEs targeting tumor-specific antigens such as interleukin 13 receptor alpha 2 (IL13RA2) and epidermal growth factor rece…

Combination of a novel TCR V{beta} chain-directed selective T cell activator with standard of care therapy for head and neck cancer improves antitumor responses and promotes regression of checkpoint-refractory tumor models

Background
Immune checkpoint blockade (ICB) treatment, alone or in combination with standard anticancer therapies, has led to important progress in the treatment of head and neck squamous cell carcinoma (HNSCC). Yet, a significant proportion of patien…

CPT1A inhibition alleviates plasmacytoid dendritic cell-mediated immune suppression in colon cancer through fatty acid oxidation modulation

Background
The tolerization of plasmacytoid dendritic cells (pDCs) within the tumor microenvironment facilitates immune evasion, thereby significantly limiting the efficacy of cancer immunotherapy. Metabolic regulators are crucial in determining immun…

Tumor-secreted AGR2 induces dendritic cell dysfunction and impairs immunotherapy efficacy in LKB1-deficient cancer

Background
LKB1 (STK11)-deficient tumors exhibit an immunosuppressive microenvironment that limits the efficacy of immunotherapies such as anti-programmed cell death protein 1 (PD-1) antibodies. However, the underlying mechanisms driving immune evasio…

Tumor-secreted AGR2 induces dendritic cell dysfunction and impairs immunotherapy efficacy in LKB1-deficient cancer

Background
LKB1 (STK11)-deficient tumors exhibit an immunosuppressive microenvironment that limits the efficacy of immunotherapies such as anti-programmed cell death protein 1 (PD-1) antibodies. However, the underlying mechanisms driving immune evasio…

TRIM28 drives immune evasion via PARP1 SUMOylation and NAD+ depletion in clear cell renal cell carcinoma

Background
Immune checkpoint blockade (ICB) therapy has demonstrated significant clinical potential in a variety of cancers; however, its efficacy in clear cell renal cell carcinoma (ccRCC) remains suboptimal. In ccRCC, an increased infiltration of CD…
