Core Viewpoint - The company, Hutchison China MediTech Limited (和黄医药), has initiated the Phase III portion of a clinical trial for surufatinib in combination with camrelizumab, nab-paclitaxel, and gemcitabine for the first-line treatment of metastatic pancreatic ductal adenocarcinoma (PDAC) patients in China, with the first patient receiving treatment on December 30, 2025 [1]. Group 1 - The study is a multicenter, randomized, open-label, positive-controlled Phase II/III clinical trial aimed at evaluating the efficacy and safety of the S+C+AG regimen compared to the AG regimen in adult patients with metastatic pancreatic cancer who have not previously received systemic anti-tumor therapy [2]. - The Phase II portion of the study included 62 patients, with plans to enroll approximately 400 additional patients in the Phase III portion [2]. - The primary endpoint of the Phase III portion is overall survival (OS), while secondary endpoints include progression-free survival (PFS), objective response rate (ORR), duration of response (DoR), disease control rate (DCR), quality of life, and safety [2]. Group 2 - Results from the Phase II portion were recently presented at the 2025 European Society for Medical Oncology (ESMO) Asia Congress, showing a median PFS of 8.15 months as of the data cutoff on July 24, 2025 [3]. - The S+C+AG group had a median PFS of 7.20 months compared to 5.52 months for the AG group, indicating a 50.1% reduction in the risk of disease progression or death (HR 0.499, p=0.0407) [3]. - Other key efficacy endpoints showed similar benefits, with an ORR of 67.7% versus 41.9% (p=0.0430) and a DCR of 93.5% versus 71.0% (p=0.0149) [3]. - Although overall survival data is not yet mature, a positive trend has been observed, with 9 events in the S+C+AG group and 15 events in the AG group [3]. - The treatment demonstrated manageable safety characteristics, with 80.6% of patients in the S+C+AG group experiencing grade 3 or higher treatment-emergent adverse events (TEAEs), compared to 61.3% in the AG group [3].
