Pembrolizumab hybrid dosing is non-inferior to flat dosing in advanced non-small cell lung cancer: a real-world, retrospective bicenter cohort study

Background
Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment but come with high costs. Alternative ICI dosing strategies could reduce costs without losing efficacy. However, clinical efficacy data are lacking.

Methods
In this r…

Clofarabine induces tumor cell apoptosis, GSDME-related pyroptosis, and CD8+ T-cell antitumor activity via the non-canonical P53/STING pathway

Background
Clofarabine (Clo) is a Food and Drug Administration (FDA)-approved drug for the treatment of acute lymphoblastic leukemia; however, its effects on solid tumors remain largely unknown.

Methods
In vitro and in vivo experiments have demonstra…

Reinforcing cancer immunotherapy with engineered porous hollow mycobacterium tuberculosis loaded with tumor neoantigens

Background
Enhancing antigen cross-presentation is essential for the development of a tumor neoantigen vaccine. One approach is to stimulate antigen-presenting cells (APCs) to uptake neoantigens. Mycobacterium tuberculosis (MTb) contains pathogen-asso…

Perioperative pembrolizumab in early-stage non-small cell lung cancer (NSCLC): safety, efficacy, and exploratory biomarker analysis

Background
Our study was designed to determine the safety, efficacy, and immunological effects of perioperative pembrolizumab in early-stage NSCLC.

Methods
This is a single-arm phase II study of perioperative pembrolizumab in patients with untreated,…

Determinants of 5-year survival in patients with advanced NSCLC with PD-L1>=50% treated with first-line pembrolizumab outside of clinical trials: results from the Pembro-real 5Y global registry

Background
Pembrolizumab monotherapy is an established front-line treatment for advanced non-small cell lung cancer (NSCLC) with programmed cell death-ligand 1 (PD-L1) tumor proportion score (TPS)≥50%. However, real-world data on its long-term effi…

Phase I study of intratumoral administration of CV8102 in patients with advanced melanoma, squamous cell carcinoma of the skin, squamous cell carcinoma of the head and neck, or adenoid cystic carcinoma

Background
CV8102, a toll-like receptor 7/8 and RIG I agonist, has demonstrated antitumor immune responses in preclinical studies. We investigated intratumoral (IT) administration of CV8102 in patients with anti-programmed cell death protein-1 (PD-1) …

Blocking the CD39/CD73 pathway synergizes with anti-CD20 bispecific antibody in nodal B-cell lymphoma

Bispecific antibodies (BsAb) have emerged as a leading treatment modality in patients suffering from B-cell non-Hodgkin’s lymphoma (B-NHL). However, treatment failure is common and may potentially be attributed to pre-existing or emerging T-cell…

Comparative impact of tertiary lymphoid structures and tumor-infiltrating lymphocytes in cholangiocarcinoma

Background
Cholangiocarcinoma is a challenging malignancy with limited responses to conventional therapies, particularly immune checkpoint inhibitor therapy. Tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLSs) are key compone…

PD-1 cis-targeted IL-2v in combination with radiotherapy inhibits lung cancer growth and remodels the immune microenvironment

Background
More efficient therapeutic options for non-small cell lung cancer (NSCLC) are needed as the survival at 5 years of metastatic disease is near zero. In this regard, we used a preclinical model of metastatic lung adenocarcinoma (SV2-OVA) to a…

First-in-human, multicenter, open-label, phase I study of ATOR-1017 (evunzekibart), a 4-1BB antibody, in patients with advanced solid malignancies

Background
ATOR-1017 (evunzekibart) is a human agonistic immunoglobulin G4 antibody targeting the costimulatory receptor 4-1BB (CD137). ATOR-1017 activates T cells and natural killer cells in the tumor environment, leading to immune-mediated tumor cel…
