Crossover-adjusted overall survival (OS) benefit with sintilimab in EGFR-TKI-resistant NSCLC: Post-hoc analysis of ORIENT-31 (ESMO Asia 2025) - P3 | "Background: In Orient-31 (NCT03802240), baseline characteristics for sintilimab+IBI305+chemo (Arm A) and chemo-alone (Arm C) groups in EGFR-TKI-resistant NSCLC were reported. This crossover-adjusted analysis demonstrates a significant overall survival benefit for sintilimab-based therapy in EGFR-TKI-resistant NSCLC. Propensity score matching confirmed robust OS improvement (23.3 vs 15.0 months; HR 0.62, 95% CI 0.41-0.96; p=0.030), indicating conventional ITT analysis underestimated treatment efficacy due to crossover contamination."

Sintilimab plus a bevacizumab biosimilar (IBI305) in advanced HCC with Child-Pugh A/B liver function: a real-world multicenter retrospective study. (PubMed, Front Oncol) - "Sin/Bev demonstrated encouraging short-term anti-tumor activity in HCC of CP-A and CP-B, while survival outcomes were affected by differences in hepatic function. Although the regimen was generally well tolerated, patients with impaired liver reserve require vigilant monitoring and comprehensive supportive strategies to maximize therapeutic outcomes."

Sintilimab plus a Bevacizumab biosimilar (IBI305) in Advanced HCC with Child-Pugh A/B liver function: A Real-World Multicenter Retrospective Study (Frontiers) - "The objective response rates (ORR) of patients with CP-A and CP-B treated with 13 Sin/Bev were 50.7% and 57.7%, respectively, and both could achieve good anti-tumor 14 efficacy. CP-B had inferior survival: median OS (15 vs 22 months, p=0.044), PFS (8 vs 14 15 months, p=0.014), and TTD (7 vs 15 months, p<0.001). The CP-B cohort demonstrated 16 comparable incidence rates of grade 3-4 AEs to the CP-A group (34.6% vs 34.2%). 17 Hemorrhagic events and thrombocytopenia emerged as predominant grade 3-4 AEs in CP-B 18 patients (15.4% for both)."

Updated Network Meta-Analysis of First-Line Systemic Treatments for Advanced HCC: Consistent Role of TACE. (PubMed, Liver Cancer) - "Transarterial chemoembolization (TACE) combined with lenvatinib provided the greatest improvement in OS over sorafenib, with a hazard ratio of 0.41 (95% confidence interval, 0.30-0.58), followed by sintilimab + IBI305 (0.57; 0.43-0.75), camrelizumab + rivoceranib (0.62; 0.48-0.80), atezolizumab + bevacizumab (0.66; 0.51-0.85), lenvatinib + pembrolizumab (0.77; 0.62-0.97), and tremelimumab + durvalumab (0.78; 0.64-0.95). For advanced HCC, our first-line analysis consistently scored TACE + lenvatinib the best for survival outcomes, followed by various immunotherapy-based combinations. However, the superior efficacy of TACE + lenvatinib should be interpreted with consideration of its derivation from a region with high hepatitis B virus prevalence."

Integrating quality of life and overall survival to quantify benefit from frontline systemic therapy options in unresectable/advanced hepatocellular carcinoma: a network meta-analysis (EASL 2025) - " Ten studies, enrolling 7,268 patients treated with Sorafenib, Lenvatinib, Nivolumab, Tislelizumab, Durvalumab, Atezolizumab+Bevacizumab, Sintilimab+IBI305, Durvalumab+Tremelimumab, Nivolumab+Ipilimumab, Atezolizumab+Cabozantinib, Lenvatinib+Pembrolizumab, Camrelizumab+Apatinib were included... Atezolizumab plus Bevacizumab was associated with the highest magnitude in reducing the risk of deterioration of most HR-QoL domains compared to other systemic therapies. Integrated assessment of OS with HR-QoL assessed by MDC suggests atezolizumab plus bevacizumab to provide the best balance between QoL preservation and OS benefit compared to other systemic therapy options in unresectable/advanced HCC."

IFITM3: A predictive biomarker for therapeutic outcomes in advanced hepatocellular carcinoma (AACR 2025) - "Extracellular vesicles (EVs) are emerging as promising tools in cancer progression and therapy assessment. Sixty-five patients with China Liver Cancer (CNLC) stage III HCC treated with hepatic artery infusion chemotherapy (HAIC) plus sintilimab and a bevacizumab biosimilar (IBI305) were stratified based on RECIST criteria and surgical status for survival analysis and Kaplan-Meier (KM) curve construction. In summary, IFITM3 levels are closely linked to therapeutic outcomes in HCC patients. Non-invasive blood-based detection of IFITM3 holds promise for enhancing therapeutic stratification. Further research may refine prediction models and deepen understanding of IFITM3's role in poor therapeutic outcomes in cancer."

Hepatic artery infusion chemotherapy (HAIC) plus sintilimab and bevacizumab biosimilar (IBI305) for initial unresectable hepatocellular carcinoma (HCC) in patients with Child-Pugh B liver function: A prospective study (ESMO 2024) - P2 | "Pts received modified FOLOFOX-HAIC (oxaliplatin 65 mg/m2, leucovorin 200 mg/m2, fluorouracil bolus 200 mg/m2, fluorouracil infusion 1200 mg/m2, every 3 weeks), with intravenous Sintilimab (200 mg) and IBI305 (7.5 mg/kg), also every 3 weeks. The modified regimen of FOLOFOX-HAIC with Sintilimab and IBI305, especially with tailored chemotherapy and targeted therapy doses, shows promising safety and efficacy for patients with unresectable HCC and Child-Pugh B liver function.

Predictive genomic biomarkers for atezolizumab plus bevacizumab combination immunotherapy response in liver cancer: Insights from the IMbrave150 trial (AACR 2024) - "Introduction: Combination immunotherapy regimens, exemplified by atezolizumab plus bevacizumab or sintilimab paired with a bevacizumab biosimilar (IBI305), have become the established standard of care for individuals with inoperable hepatocellular carcinoma (HCC)...Our aim is to evaluate whether previously defined immune signature scores (ISS) from the TCGA pan-cancer study can identify HCC patients likely to derive enhanced benefit from the combination immunotherapy. We applied ISS predictor to gene expression data from IMbrave150 clinical trial in which HCC patients were treated with atezolizumab plus bevacizumab or sorafenib and stratify the patients into responders and non-responders (cutoff of 0.5)... Our study suggests that ISS may serve as a promising predictive biomarker for enhanced therapeutic outcomes in patients undergoing combination immunotherapy for HCC. The identification of such markers is crucial for refining patient stratification and personalized..."
