Nivolumab adjuvant to chemo-radiation in localized muscle-invasive urothelial cancer: primary analysis of a multicenter, single-arm, phase II, investigator-initiated trial (NEXT)

Background
Muscle-invasive urothelial cancer (UC) has a high risk of recurrence after definitive treatment. Nivolumab adjuvant to radical surgery improves disease-free survival in patients with UC with a high risk of recurrence; however, its role adju…

New soluble CSF-1R-dimeric mutein with enhanced trapping of both CSF-1 and IL-34 reduces suppressive tumor-associated macrophages in pleural mesothelioma

Background
Colony stimulating factor-1 receptor (CSF-1R) and its ligands CSF-1 and interleukin (IL)-34 have tumorigenic effects through both induction of suppressive macrophages, and survival/proliferation of tumor cells. In addition, the IL-34 tumori…

Phase 2 study of neoadjuvant durvalumab plus docetaxel, oxaliplatin, and S-1 with surgery and adjuvant durvalumab plus S-1 for resectable locally advanced gastric cancer

Background
Based on the phase 3 PRODIGY study, neoadjuvant docetaxel, oxaliplatin, and S-1 (DOS) have emerged as a viable treatment option for Asian patients with resectable locally advanced gastric cancer (LAGC). This phase 2 study evaluated the effi…

Leveraging T cell co-stimulation for enhanced therapeutic efficacy of trispecific antibodies targeting prostate cancer

Background
Clinical trials have demonstrated the efficacy of bispecific antibodies in eliciting potent antitumor responses by redirecting T cells to target cancer cells, particularly for the treatment of hematologic malignancies. However, their effica…

Cell-intrinsic PD-L1 signaling drives immunosuppression by myeloid-derived suppressor cells through IL-6/Jak/Stat3 in PD-L1-high lung cancer

Background
Some patients with non-small-cell lung cancer (NSCLC) benefit from immune checkpoint inhibitors (ICIs) despite programmed death-ligand 1 (PD-L1) expression. To address the mechanism of ICI resistance in PD-L1-positive NSCLC, we investigated…

Safety and efficacy of immune checkpoint therapy for the treatment of patients with cardiac metastasis: a multicenter international retrospective study

Background
Data on the safety profiles and clinical outcomes of patients with solid tumors and cardiac metastasis treated with immune checkpoint inhibitors (ICIs) are limited.

Methods
This is an international multicenter retrospective study of patien…

Frizzled-7-targeting antibody-derived bifunctional protein retargets NK cells against triple-negative breast cancer cells via MICA-NKG2D axis

Background
Hypoxia is associated with the evasion of triple-negative breast cancer (TNBC) from immune surveillance. Hypoxia increases the subpopulation of putative TNBC stem-like cells (TNBCSCs) through activating Wnt/β-Catenin signaling. The she…

T-cell immune checkpoint inhibition plus hypomethylation for locally advanced HER2-negative breast cancer: a phase 2 neoadjuvant window trial of decitabine and pembrolizumab followed by standard neoadjuvant chemotherapy

Background
Higher levels of tumor-infiltrating lymphocytes (TILs) in breast cancers are associated with increased likelihood of pathologic complete response (pCR) to chemotherapy. DNA methyltransferase inhibitors (DNMTi) can augment immune responses t…

Phase I study of ribociclib (CDK4/6 inhibitor) with spartalizumab (PD-1 inhibitor) with and without fulvestrant in metastatic hormone receptor-positive breast cancer or advanced ovarian cancer

Background
Preclinical evidence suggests that cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitors enhance antitumor immunity. We conducted a phase I trial of ribociclib (CDK4/6 inhibitor) plus spartalizumab (PD-1 inhibitor) in patients with hormone r…

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 …
