SBRT + Ipilimumab N01 + Sintilimab + AG Chemotherapy
SBRT + Ipilimumab N01 + Sintilimab + AG Chemotherapy: Participants will receive stereotactic body radiotherapy at 5-10 Gy in 5 fractions, followed one week later by sequential systemic therapy with ipilimumab N01, sintilimab, nab-paclitaxel, and gemcitabine. Ipilimumab N01 will be administered at 1 mg/kg intravenously every 6 weeks for a total of 4 doses. Sintilimab will be administered at 200 mg intravenously every 3 weeks. Nab-paclitaxel 125 mg/m² and gemcitabine 1000 mg/m² will be administered on Days 1 and 8 of each 3-week cycle. AG chemotherapy will be given for 6 to 8 cycles, and sintilimab may continue as maintenance therapy until disease progression or other protocol-specified discontinuation criteria.
Study summary
This is a Phase II, prospective, single-arm exploratory clinical trial designed to evaluate the efficacy and safety of stereotactic body radiotherapy followed by ipilimumab N01 plus sintilimab in combination with nab-paclitaxel and gemcitabine in patients with locally advanced pancreatic cancer. Eligible patients will receive SBRT followed by sequential systemic therapy. The primary endpoint is progression-free survival, and secondary endpoints include overall survival, disease control rate, duration of response, objective response rate, and safety.

Primary outcome measure(s)
Progression-Free Survival (PFS) — From initiation of study treatment until disease progression or death, assessed up to 36 months Progression-free survival is defined as the time from the initiation of study treatment to the first documented disease progression according to RECIST 1.1 or death from any cause, whichever occurs first.
