Biomarkers of activity from a phase I study of cergutuzumab amunaleukin in patients with advanced solid tumors

Background
Cergutuzumab amunaleukin (CA) is an immunocytokine comprising an anticarcinoembryonic antigen (CEA) linked to an interleukin-2 (IL-2) variant. CA does not bind to CD25 (IL-2 receptor α) and was designed to maintain the T and natural k…

Therapeutic vaccination for glioblastoma elicited by retargeted oncolytic herpes virus

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…

Steroid-sparing strategies for managing immune-related adverse events

Although immune checkpoint inhibitors (ICI) have greatly improved outcomes in several cancer types, their use is also associated with immune-related adverse events (irAEs) that can impact any organ system and lead to significant morbidity and even mor…

An Immune-privileged niche mediates immunotherapy resistance in esophageal carcinoma

Background
Neoadjuvant immunotherapy has reshaped the treatment paradigm for esophageal squamous cell carcinoma (ESCC), yet mechanisms of resistance in non-responders remain poorly understood. Specifically, the spatial orchestration of the tumor micro…

CD47 destabilization via manipulating the SPOP-USP2 axis augments macrophage phagocytosis and cancer immunotherapy

Background
Macrophages can eliminate cancer cells through phagocytosis via the CD47/signal regulatory protein α axis, which provides promising targets for cancer immunotherapy as innate immune checkpoints. Although CD47 is overexpressed in multi…

Trispecific targeting of T cells engineered with TCR mimic antibodies to limit antigen escape

Background
Antigen loss and tumor heterogeneity present significant challenges for successful immunotherapies. T-cell receptor (TCR)-based therapies rely on the recognition of epitopes derived from intracellular tumor proteins presented by major histo…

Tumor-associated macrophages educated by IGSF9 exhibit a senescence-associated secretory phenotype to promote tumor immune escape

Background
IGSF9, immunoglobulin superfamily member 9, has been reported to inhibit T cell proliferation and activation, thereby promoting tumor immune escape. Tumor-associated macrophages (TAMs), the most abundant tumor-infiltrating immune cells, pla…

Neoadjuvant lenvatinib plus pembrolizumab in Merkel cell carcinoma: an investigator-initiated, open-label phase II trial

Background
Given the success of checkpoint inhibitor therapy in the advanced Merkel cell carcinoma (MCC) setting, there is interest in exploring immunotherapy as a neoadjuvant approach. We report the primary results of a neoadjuvant study of lenvatini…
