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.
This study is a Phase II, prospective, single-arm exploratory clinical trial in patients with locally advanced pancreatic cancer. The study aims to explore the efficacy and safety of stereotactic body radiotherapy followed by ipilimumab N01 plus sintilimab in combination with nab-paclitaxel and gemcitabine. Eligible patients will first receive stereotactic body radiotherapy at a dose of 5-10 Gy for 5 fractions. One week after completion of SBRT, patients will receive sequential systemic therapy consisting of 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 will be administered at 125 mg/m² on Days 1 and 8, and gemcitabine will be administered at 1000 mg/m² on Days 1 and 8 of each 3-week cycle. Nab-paclitaxel and gemcitabine will be given for 6 to 8 cycles, and sintilimab may be continued as maintenance treatment until disease progression, unacceptable toxicity, withdrawal of consent, initiation of new anti-cancer therapy, death, or other protocol-specified reasons. Tumor assessments will be performed regularly according to RECIST 1.1. The primary endpoint is progression-free survival. Secondary endpoints include overall survival, disease control rate, duration of response, objective response rate, and safety. Adverse events will be monitored throughout the study and graded according to applicable safety criteria.

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.

Progression-Free Survival (PFS)
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.
Time frame: From initiation of study treatment until disease progression or death, assessed up to 36 months
Overall Survival (OS)
Overall survival is defined as the time from initiation of study treatment to death from any cause.
Time frame: From initiation of study treatment until death from any cause, assessed up to 36 months
Disease Control Rate (DCR)
Disease control rate is defined as the proportion of participants who achieve complete response, partial response, or stable disease according to RECIST 1.1.
Time frame: From initiation of study treatment until disease progression or death, assessed up to 36 months
Duration of Response (DoR)
Duration of response is defined as the time from the first documented complete response or partial response to disease progression or death from any cause, whichever occurs first.
Time frame: From first documented response until disease progression or death, assessed up to 36 months
Objective Response Rate (ORR)
Objective response rate is defined as the proportion of participants who achieve complete response or partial response according to RECIST 1.1.
Time frame: From initiation of study treatment until disease progression or death, assessed up to 36 months
Incidence and Severity of Adverse Events
Safety will be assessed by the incidence and severity of adverse events and serious adverse events, graded according to applicable safety criteria.
Time frame: From initiation of study treatment until 30 days after the last dose of study treatment
