4-1BB agonist targeted to fibroblast activation protein {alpha} synergizes with radiotherapy to treat murine breast tumor models

Background
Ionizing radiation (IR) is a double-edged sword for immunotherapy as it may have both immunosuppressive and immunostimulatory effects. The biological effects of IR on the tumor microenvironment (TME) are a key factor for this balance. Fibro…

TIGIT inhibitor M6223 as monotherapy or in combination with bintrafusp alfa in patients with advanced solid tumors: a first-in-human, phase 1, dose-escalation trial

Background
M6223 is an intravenous (IV), Fc-competent, fully human, antagonistic, anti-T cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domains (TIGIT) antibody. Bintrafusp alfa (BA) is a bifunctional fusion…

Phase I study of efineptakin alfa (NT-I7) for the treatment of Kaposi sarcoma

Background
CD4+ T-cell lymphocytopenia and immune dysfunction are factors that drive the onset and persistence of Kaposi sarcoma (KS) in people with (PWH) and without HIV. Standard chemotherapy agents for KS can contribute to increasing CD4+ T cell ly…

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…
