Multiplex immunofluorescence based spatial analysis of HER2 positive breast cancer patients treated with bintrafusp alfa: A translational pathology study (AACR 2026) - P1 | "Combined PD-L1 and TGFβ inhibition with Bintrafusp Alfa promotes heterogeneous spatial reprogramming of the breast cancer microenvironment. Beneficial remodeling is characterized by mixed epithelial and immune clusters, intratumoral cytotoxic and memory T cell infiltration, and checkpoint rich interfaces, while refractory cases are defined by persistent epithelial cohesion and suppressive myeloid environments. Overall, spatial compartmentalization, checkpoint expansion, and immune clustering emerged as indicators of response intensity."

Peripheral immune dynamics and biomarkers of clinical response in patients with castration-resistant prostate cancer treated with combination immunotherapy* (AACR-IO 2026) - P1/2 | "The phase I/II Quick Efficacy Seeking Trial (QuEST1, NCT03493945) evaluating the potential of combination immunotherapy in CRPC was designed to generate a tumor-directed immune response with BNVax (a vaccine targeting brachyury, a transcription factor linked to invasion/metastasis) and facilitate the resulting anti-tumor activity with ICB (with bintrafusp alfa (BA), a bifunctional dual inhibitor of PD-L1 and TGF-β) and a lymphocyte stimulating immunocytokine (the IL-15 receptor superagonist nogapendekin alfa inbakicept-pmln (NAI), also known as N-803). These findings indicate that the addition of NAI to tumor-targeted vaccine and ICB results in increased clinical activity, enhanced ALC levels, and immune activation of both NK and T cells. These observations warrant further investigation of easily accessible peripheral biomarkers, including ALC, in patients with CRPC and suggest that evaluation of an array of circulating biomarkers may be beneficial in predicting..."

Comparative efficacy and safety of targeted therapeutics or immunotherapy agents combined with chemotherapy as first-line treatment for advanced biliary tract cancer: a systematic review and network meta-analysis. (PubMed, BMC Cancer) - "Our findings directly inform clinical guidelines, address gaps in current therapeutic decision-making. Durvalumab or pembrolizumab combined with GC are optimal first-line regimens for advanced BTC, balancing survival benefits and safety. Sintilimab plus anlotinib combined with GC demonstrates superior PFS but requires further validation. While EGFR inhibitors plus chemotherapy demonstrate potential in KRAS wild-type patients, confirmation in large-scale RCTs is required. PD-L1 expression may represent a promising predictive biomarker for response to PD-1 inhibitor therapy."

HCB301: A Novel Tri-Specific Fc Fusion Protein Targeting PD-L1, CD47, and TGFβ Remodels the Tumor Microenvironment and Enhance Anti-Tumor Immunity (SITC 2025) - "In vivo efficacy was evaluated using NPG™ mice bearing FaDu (HNSCC)/human PBMC co-mixed xenografts, as well as hPD1/hPDL1/hCD47/hSIRPα transgenic BALB/c mice bearing 4T1-hPDL1/hCD47 tumors.Results HCB301 effectively blocked PD-L1 signaling at a level comparable to atezolizumab and suppressed TGF-β1 activity more potently than M7824, a clinically studied bifunctional fusion protein targeting PD-L1 and TGFβ.4 Importantly, HCB301 induced robust phagocytosis of PD-L1-high, CD47-positive cancer cells by human MDMs while showing no off-target phagocytosis of red blood cells. This contrasts with magrolimab analogs and suggests a favorable hematologic safety profile, mitigating concerns observed with some CD47-targeting agents.5 In vivo, HCB301 elicited robust anti-tumor activity, equivalent to a triple-agent combination targeting PD-L1, CD47, and TGF-β individually, in both FaDu and 4T1 tumor models.Conclusions HCB301 represents a novel therapeutic approach that simultaneously..."

Early changes in serum proteomic profiles predict anti-tumor activity in patients with advanced HPV-associated malignancies treated with novel combination immunotherapy (SITC 2025) - P1/2 | "Background We previously reported on the clinical activity of an HPV16 cancer vaccine (PDS0101), a tumor-targeting IL-12 immunocytokine (NHS-IL12, PDS01ADC), and a bifunctional agent targeting PD-L1 and TGF-β (bintrafusp alfa, BA) for the treatment of advanced HPV-associated malignancies, which demonstrated promising clinical activity (NCT04287868).1 Here, we perform a comprehensive survey of the peripheral immunome from patients treated with this novel immunotherapeutic combination to query systemic immunological changes and build models predicting clinical response.Methods Peripheral blood was serially collected from patients (n=50) for HPV16 circulating tumor DNA (ctDNA) detection, qualitative serum proteome profiling with the Olink ImmunoOncology platform, and immunophenotyping by flow cytometry. These data pave the way for outcome prediction in patients with HPV-associated malignancies using readily quantifiable molecular correlates from peripheral blood and..."

Early kinetics of circulating tumor HPV-16 and HPV-18 DNA are associated with survival in patients with HPV-associated cancers treated with dual blockade of PD-L1 and TGF-β (SITC 2025) - P2 | "Immune checkpoint blockade (ICB) with a dual inhibitor of programmed cell death ligand 1 (PD-L1) and transforming growth factor β (TGFβ), induced clinical responses in 30.5% of patients with HPV-associated malignancies who were ICB-naïve and 10% who were ICB-resistant.1 2 Circulating tumor DNA (ctDNA) is a promising, non-invasive tool for monitoring tumor dynamics and potentially predicting therapeutic outcomes; however, few studies have evaluated ctDNA kinetics in patients with HPV-associated malignancies treated with immunotherapy.3 We evaluated HPV16/18-ctDNA as a predictive biomarker of clinical response and survival in patients with HPV-associated malignancies treated with dual blockade of PD-L1 and TGF-β.Methods Peripheral blood was collected before and after 1 and 3 cycles of administration of a dual inhibitor of PD-L1 and TGF-β, bintrafusp alfa, in 51 patients with HPV16/18-associated cancers (NCT03427411)...These data support the continued..."
