Background
The efficacy of combined chemotherapy and programmed cell death protein-1 (PD-1) immune checkpoint blockade (ICB) is constrained by the collateral cytotoxicity of chemotherapy toward proliferating tumor-specific CD8+ T (TTST) cells, a popul…
Background
Antitumor immune responses induced by oncolytic immunotherapy (OI) are often followed by upregulation of programmed death-ligand 1 (PD-L1). As such, the combination of OI with blockade of the programmed cell death protein-1 (PD-1)/PD-L1 axi…
Purpose
ASP9801, an oncolytic virus encoding interleukin-7 and interleukin-12, was assessed for safety, tolerability, pharmacokinetics, and antitumor activity in patients with advanced solid tumors in a Phase 1 study.
Methods
The study comprised Part…
Background
Prostate cancer (PCa) is a prevalent malignancy with limited treatment options for advanced stages. Oncolytic virotherapy represents a promising immunotherapeutic approach, but its efficacy and underlying mechanisms in PCa, particularly con…
Background
Nanosecond pulsed electric field (nsPEF) ablation has demonstrated limited and transient efficacy in suppressing tumor progression. Oncolytic peptide LTX-315 is known to elicit a strong antitumor immune response and durable immune memory. T…
Introduction
An adaptive immune response to cancer requires three main signals: antigen presentation and recognition (“signal 1”), costimulation (“signal 2”), and secreted immunostimulatory cytokines (“signal 3”). Expression of these signals in tumors…
Background
Cysteine–cysteine chemokine receptors 2 (CCR2) and 5 (CCR5) contribute to immune suppression in tumor microenvironments. CCR2 and CCR5 antagonists have demonstrated antitumor activity in pancreatic ductal adenocarcinoma (PDAC) and col…
Background
Oncolytic viruses are tumor-specific immunotherapeutic agents that exploit inherent features of the tumor microenvironment to replicate, spread, and kill cancer cells. The exchange protein activated by cAMP (EPAC) is a cell signaling protei…
Background
Glioblastoma is an aggressive tumor with poor prognosis and limited treatment options due to its resistance to chemotherapy and radiotherapy, high heterogeneity, and ability to evade the immune system. Nevertheless, immunotherapy and oncoly…
Background
Oncolytic herpes simplex virus (oHSV) therapy is a live virus-based immunotherapy that lyses tumor cells which release antigens and activate antitumor immunity. oHSV therapy has been shown to increase ATP production and release of extracell…
