A Phase I Study of WM-S1-030 in Patients With Advanced Solid Tumors
Ontology highlight
ABSTRACT: This study evaluates the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of WM-S1-030 in patients with advanced solid tumors.
Project description:Macrophage Clever-1 contributes to impaired antigen presentation and suppression of anti-tumor immunity. This first-in-human trial investigates the safety and tolerability of Clever-1 blockade with bexmarilimab in patients with treatment-refractory solid tumors and assesses preliminary anti-tumor efficacy, pharmacodynamics and immunologic correlates. Bexmarilimab shows no dose-limiting toxicities in part I (n=30) and no additional safety signals in part II (n=108). Disease control (DC) rates of 25%-40% are observed in cutaneous melanoma, gastric, hepatocellular, estrogen receptor-positive breast, and biliary tract cancers. DC associates with improved survival in a landmark analysis and correlates with high pre-treatment intratumoral Clever-1 positivity and increasing on-treatment serum interferon γ (IFNγ) levels. Spatial transcriptomics profiling of DC and non-DC tumors demonstrates bexmarilimab-induced macrophage activation and stimulation of IFNγ and T cell receptor signaling selectively in DC patients. These data suggest that bexmarilimab therapy is well tolerated and show that macrophage targeting can promote immune activation and tumor control in late-stage cancer.
Project description:A Phase 1 Study to Investigate the Safety, Tolerability, Pharmacokinetics/Pharmacodynamics, and Antitumor Activity of NM1F as Monotherapy and in Combination with Pembrolizumab in Subjects with Locally Advanced/Metastatic Solid Tumors
Project description:Biopsy samples from 4 sites were collected for RNA-Seq and single-cell RNA-Seq from patients with HER2 positive tumors enrolled in a Phase 1 clinical trial of anti-HER2 CAR-macrophage cell therapy. Biopsies of solid tumors were aimed to be collected at screening, 8 days after treatment, and 4 weeks after treatment. Patients in Group 1 received dose escalation of intravenous administration of up to 500 million cells, 1.5 billion cells, and 3 billion cells, on Day 1, 3, and 5, respectively. Patients in Group 2 received their full dose of cells on Day 1. This trial aimed to determine the feasibility of manufacturing CAR-macrophages, as well as assess the safety and tolerability of CAR-macrophage therapy, and determine the severity of potential adverse events.
Project description:This study evaluates the safety, tolerability, preliminary efficacy and pharmacokinetics of Simmitecan in patients with advanced solid tumors and Simmitecan, 5-fluorouracil and Leucovorin Calcium,thalidomide in patients with advanced solid tumor or advanced/metastatic colorectal cancer.
Project description:Many cancer patients don’t benefit from currently-approved immune checkpoint inhibitors (ICI), suggesting that additional immunomodulation of the immunosuppressive tumour microenvironment (TME) is required. MTL-CEBPA specifically upregulates expression of master myeloid transcription factor, CEBPA, relieving myeloid-driven immunosuppression. Here, we report the safety, tolerability, pharmacokinetics, and efficacy of MTL-CEBPA in combination with pembrolizumab in patients with advanced solid tumours that typically show ICI resistance. Multimodal exploratory analyses of paired patient biopsies demonstrate biological changes associated with combination treatment of MTL-CEBPA and pembrolizumab, including increased infiltration of T cell and antigen-presenting cells supporting conversion from an immune desert towards a more immune-inflamed TME. Patients with disease stabilisation demonstrate reductions in immunosuppressive myeloid cells post-treatment. Collectively, these data support a role for MTL-CEBPA in reducing immunosuppression in the TME. This study was registered at ClinicalTrials.gov (NCT04105335). This manuscript also reports proteomic data from patients treated with MTL-CEBPA in combination with sorafenib from clinical trial, OUTREACH, accessible at ClinicalTrials.gov, number NCT02716012 and reported. Stored plasma from patients from this clinical trial were analysed using OLINK as described below.
Project description:The purpose of this Phase I, Multi-Center, Open-Label Study is to evaluate the safety, tolerability, Pharmacokinetics, Pharmacodynamics and anti-tumor activity of KF-0210 in participants with advanced solid tumors. The study will be conducted in two parts: phase Ia, and phase Ib.
Project description:ACE1702 (anti-HER2 oNK cells) is an off-the-shelf Natural Killer (NK) cell product that targets human HER2-expressing solid tumors. The ACE1702-001 phase I study aims to evaluate the safety and tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of ACE1702 in patients with advanced or metastatic HER2-expressing tumors, and to determine the phase Ib/II starting dose for ACE1702.
