Sulfatinib and Serplulimab Combined With AG Regimen as Conversion Therapy for Patients With Locally Advanced Pancreatic Cancer : A Single-arm, Phase II Study(SAGE)
Study Details
Study Description
Brief Summary
This is a phase 2, single-arm clinical study. The purpose of this study is to explore the efficacy and safety of sulfatinib and serplulimab in combination with gemcitabine and albumin-paclitaxel in the conversion therapy for patients with unresectable locally advanced pancreatic cancer.

| Phase 2 |
Detailed Description
The trial will recruit 42 patients. Enrolled patients received sulfatinib in combination with serplulimab and AG regimen chemotherapy. Within 6 cycles of conversion therapy, the investigator will assess whether the patient has potential R0 resection possibility according to imaging results every 2 cycles (±7 days). For patients who underwent R0 resection, adjuvant therapy with sulfatinib combined with serplulimab and AG regimen was performed within 12 weeks after surgery, and the adjuvant therapy before and after surgery was performed for a total of 6 cycles. Perioperative treatment lasted about 6 months, followed by sulfatinib combined with serplulimab for 1 year. Patients who cannot undergo surgery or have R1, R2 resection will be given sulfatinib combined with serplulimab for maintenance treatment up to 2 years, or until intolerance, disease progression, death or other criteria specified in the protocol for discontinuation of study treatment are met.

Outcome Measures
Primary Outcome Measures
- R0 Surgical Resection Rate [Up to 2 years]
Proportion of patients with negative microscopic margins (no tumor cell remains)
Secondary Outcome Measures
- Surgical conversion rate [Up to 2 years]
Surgical conversion rate: the proportion of patients with successful conversion and surgical resection in all patients, surgical conversion rate =(number of patients with successful conversion and surgical resection/total number of patients) ×100%.
- Objective response rate (ORR) [Up to 2 years]
ORR is defined as the percentage of patients who have achieved complete response (CR) or partial response (PR), as measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria
- Deepness of response (DpR) [Up to 2 years]
DpR is defined as the percentage of maximal tumor reduction from baseline of a target lesion.
- Progression-Free Survival (PFS) [Up to 2 years]
PFS is defined as the time from the first dose of administration to progression or death
- Disease-free survival (DFS) [Up to 2 years]
DFS is defined as the time interval between the date of enrollment and the date of the first documented evidence of relapse after radical resection at any site or death related to cancer
- Over Survival (OS) [Up to 2 years]
OS is defined as the time from first treatment to death, regardless of disease recurrence
