Biliary tract cancer (BTC) has a poor prognosis with limited treatment options. This phase 2 trial randomized 80 patients with unresectable/metastatic BTC 1:1 to sintilimab, anlotinib, and gemcitabine/cisplatin (SAGC) or chemotherapy alone (GC). At 13.4-month median follow-up, SAGC significantly improved median progression-free survival (8.5 vs. 6.3 months; HR 0.48, 95% CI 0.22-0.64, p = 0.005) and objective response rate (51.4% vs. 29.4%), with higher grade 3/4 adverse events (75.0% vs. 43.6%). Post hoc analysis showed enhanced efficacy with anlotinib 8 mg versus 10 mg (ORR 54.5% vs. 38.8%). In AKT/YAP tumor models, low-dose anlotinib (3 mg/kg) combined with sintilimab improved vascular perfusion, T-cell cytotoxicity, and cytokine secretion compared to high-dose (6 mg/kg). These findings demonstrate improved efficacy and manageable toxicity with SAGC, particularly at the 8 mg anlotinib dose, suggesting low-dose regimens may optimize antitumor response while mitigating adverse effects. Trial registration number ClinicalTrials.gov Identifier: NCT04300959.

Background: Although immune checkpoint inhibitors (ICIs) have markedly improved first-line management of non-small cell lung cancer (NSCLC), many tumors eventually escape control after anti-PD-(L)1 therapy, leaving a clear therapeutic gap. Preclinical studies and preliminary clinical data suggest that coupling ICIs with anti-angiogenesis therapy can yield complementary antitumor effects. Consequently, we launched this investigation to evaluate the therapeutic benefit and tolerability of sintilimab, a PD-(L)1-blocking monoclonal antibody, together with the oral multi-target anti-angiogenesis agent anlotinib in metastatic NSCLC individuals experiencing progression after first-line PD-(L)1 inhibition.

Advanced sarcomas have limited treatment options after standard therapy, and therefore we investigated the efficacy and safety of sintilimab plus anlotinib in this setting. Patients aged 18-75 years with advanced sarcomas and prior systemic therapy were enrolled. Patients with untreated, primary chemotherapy-resistant tumor types, such as alveolar soft part sarcoma, clear cell sarcoma, etc.

Background: Lung cancer is a leading cause of cancer-related deaths. Perioperative therapies, including neoadjuvant chemo-immunotherapy, have improved outcomes, but combining them with antiangiogenic drugs may offer further benefits. This study evaluated the 3-year efficacy and safety of neoadjuvant sintilimab, anlotinib, and chemotherapy in resectable NSCLC patients from the TD-NeoFOUR trial.

Background: Our phase 2 study has shown the efficacy and safety of sintilimab plus anlotinib as second- or later-line therapy in patients with programmed death-ligand 1 (PD-L1)-positive recurrent or metastatic cervical cancer who had failed prior chemotherapy. Here, we presented updated survival outcomes after a 3-year follow-up.
Methods: Patients received a regimen comprising 200 mg of sintilimab administered once on day 1 and 10 mg of anlotinib once daily on days 1-14 every 3 weeks.
