Molecular profiling of NSCLC patients associates CT-based radiomic features with a tumor microenvironment favorable for immunotherapy (AACR 2025) - P1/2, P2 | "Here, we integrate radiomics with tumor transcriptomic profiles to enhance biological interpretation of CT-based features linked to an immune-responsive tumor microenvironment (TME), in non-small cell lung cancer (NSCLC) treated with acasunlimab, a DuoBody® PD-L1×4-1BB bispecific antibody, +/- pembrolizumab.This study used contrast-enhanced CT images (n=62) and gene expression (HTG EdgeSeq) from tumor biopsies (n=25) of advanced NSCLC subjects in GCT1046-01 (NCT03917381) and GCT1046-04 (NCT05117242). Gabor was negatively correlated with cancer associated fibrosis and extracellular matrix remodeling.These results show that integrating radiomics with tumoral mRNA data identified key characteristics of a TME conducive for immunotherapy, advancing the interpretability of AI-derived imaging features. The composite radiomics score was independent of traditional prognostic factors and reflected immunotherapy-specific mechanisms, highlighting its potential..."

Acasunlimab combined with PD-1 blockade elicits complementary immune-modulatory effects and enhances anti-tumor activity in preclinical models (SITC 2024) - P2 | "Conclusions Our results indicate that combining acasunlimab with additional PD-1 blockade may amplify the anti-tumor immune response by promoting autocrine IL-2–CD25 signaling and increasing the proportion of stem-like CD8+ TILs with effector functions. These results contribute to the growing evidence supporting the potential of combining acasunlimab with pembrolizumab to elicit durable clinical responses.4 Ethics Approval Animal experiments were performed according to the guidelines of the Institutional Animal Care and Use Committee (IACUC) and in accordance with the regulations of the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC)."

Dosing Regimen for Acasunlimab (DuoBody-PD-L1x4-1BB) In Combination with Pembrolizumab (IASLC-WCLC 2024) - P2 | "PD results support the hypothesis that intermittent 4-1BB engagement reduces chronic T-cell stimulation, potentially mitigating T-cell dysfunction by allowing a resting interval and resetting of T-cell function. This may improve the magnitude and quality of antitumor immune responses and result in improved durability in the clinical setting."

Acasunlimab (DuoBody-PD-L1x4-1BB) alone or in combination with pembrolizumab (pembro) in patients (pts) with previously treated metastatic non-small cell lung cancer (mNSCLC): Initial results of a randomized, open-label, phase 2 trial. (ASCO 2024) - P2 | "Given failures of recent trials in this setting, single-agent chemotherapy remains the main tx option despite limited effectiveness (eg, docetaxel ORR 10–14%) and considerable toxicity. In PD-L1+ pts with mNSCLC following progression on prior CPI tx, acasunlimab + pembro combo showed a manageable safety profile and promising efficacy, with deeper responses and durable disease control in pts treated Q6W. Enrollment is ongoing."
