Effect of prior and first-line immunotherapy on baseline immune biomarkers and modulation of the tumor microenvironment in response to nivolumab and relatlimab combination therapy in patients with melanoma from RELATIVITY-020

Background
Some patients with melanoma experience disease progression during immunotherapy (IO) and may benefit from novel combinations of immune checkpoint inhibitors (ICIs). We report results from exploratory biomarker analyses to characterize the r…

Effector T cells under hypoxia have an altered transcriptome similar to tumor-stressed T cells found in non-responsive melanoma patients

Background
In the tumor microenvironment (TME), hypoxia stands as a significant factor that modulates immune responses, especially those driven by T cells. As T cell-based therapies often fail to work in solid tumors, this study aims to investigate th…

Association of 5{alpha}-reductase inhibitor prescription with immunotherapy efficacy in metastatic renal cell carcinoma: a multicenter retrospective analysis

Background
Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic renal cell carcinoma (mRCC), but response rates remain heterogeneous, and reliable predictive biomarkers are lacking. Recent studies suggest that androgen r…

Targeted delivery of CCL3 reprograms macrophage antigen presentation and enhances the efficacy of immune checkpoint blockade therapy in hepatocellular carcinoma

Background
Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related deaths worldwide, especially in advanced stages where limited treatment options result in poor prognosis. The immunosuppressive tumor immune microenvironment (TIME), c…

Phosphatidylserine as a tumor target for CAR-T cell therapy

Background
Phosphatidylserine (PS) exposed on apoptotic cells promotes immune clearance of dead cells without inducing inflammation. Conversely, PS exposure on live tumor cells promotes an immunosuppressive tumor microenvironment that hinders antitumo…

Ethanol inhibits the growth and metastasis of hepatocellular carcinoma by inducing immunogenic cell death

Background
Immunogenic cell death (ICD) can elicit an adaptive immune response with significant antitumor effects. Percutaneous ethanol injection therapy has been applied as tumor ablation for small hepatocellular carcinoma (HCC). However, it was not …

Mimicry-based strategy between human and commensal antigens for the development of a new family of immune therapies for cancer

Background
Molecular mimicry between commensal bacterial antigens and tumor-associated antigens (TAAs) has shown potential in enhancing antitumor immune responses. This study leveraged this concept using commensal bacterial antigens, termed OncoMimics…

Corticosteroid premedication on anti-tumor effect of immune checkpoint blockade in murine hepatocellular carcinoma models

Background and aims
Corticosteroid is effective in alleviating immune-related adverse events (irAEs) of immune checkpoint blockade (ICB). However, prophylactic use of corticosteroid to prevent irAEs is not recommended due to a looming concern that it …

Phase I dose-escalation and pharmacodynamic study of STING agonist E7766 in advanced solid tumors

E7766 is a novel stimulator of interferon genes (STING) agonist, capable of potent activation of immune cells and generating strong antitumor response in preclinical murine tumor models. Here we present the safety, efficacy, and biomarker results of t…

Skin mutation burden drives adaptive immunity and response to immunotherapy

Numerous studies over the past century have reported an inverse correlation between lifetime solar ultraviolet radiation (UV) exposure and all-cancer incidence and mortality. For decades, this relationship was hypothesized to reflect the action of pho…
