Surufatinib and Serplulimab Combined With AG Regimen Compare With AG Regimen as Conversion Therapy for Patients With Locally Advanced Pancreatic Cancer (SAGE)

Surufatinib and Serplulimab Combined With AG Regimen Compare With AG Regimen as Conversion Therapy for Patients With Locally Advanced Pancreatic Cancer : a Phase II Randomized Controlled PILOT Study (SAGE)

This is a Phase II Randomized Controlled PILOT clinical study. The purpose of this study is to explore the efficacy and safety of surufatinib and serplulimab in combination with albumin-paclitaxel and gemcitabine in the conversion therapy for patients with unresectable locally advanced pancreatic cancer. Furthermore, it compares the efficacy of surufatinib and serplulimab in combination with albumin-paclitaxel and gemcitabine to the albumin-paclitaxel and gemcitabine regimen in the conversion therapy for patients with unresectable locally advanced pancreatic cancer.

Study Overview

• Status: Not yet recruiting
• Conditions: Locally Advanced Pancreatic Cancer
• Intervention / Treatment: Drug: Albumin-paclitaxel + Gemcitabine; Drug: Surufatinib + Serplulimab+Albumin-paclitaxel + Gemcitabine

Detailed Description

A total of 50 participants are expected to be enrolled in this study; 25 will receive the surufatinib and serplulimab in conjunction with albumin-paclitaxel and gemcitabine regimen and 25 will receive the AG regimen. The participants who have been enrolled will initially undergo two cycles of albumin-paclitaxel and gemcitabine induction chemotherapy. The researcher will assess the patients' efficacy based on their imaging results after the second cycle. Patients with PD will be excluded from this trial, and patients with SD, PR, or CR will be enrolled. Patients will be randomly chosen to receive either the AG regimen for 2-4 cycles or the surufatinib combined with serplulimab and AG regimen for 2-4 cycles. Every two cycles, the researcher assessed the effectiveness of the patients' treatments and the potential for R0 resection. Then, patients with PD were removed from the group, those who could be operated were enrolled for surgical resection, and those without PD and unable to undergo surgery were finished with a total of 6 cycles of either the AG regimen chemotherapy or surufatinib combined with serplulimab and the AG regimen chemotherapy. Within 12 weeks of surgery, patients underwent 0-2 cycles of chemotherapy with the AG regimen or surufatinib combined with serplulimab and AG regimen, totaling 6 cycles of postoperative chemotherapy. Then patients of AG group will enter follow up stage. Patients with R0 resection will accept surufatinib in combination with serplulimab maintenance for no longer than 12 cycles after surgery, or until intolerability, progressive disease, death, or other criteria for study treatment discontinuation specified in the protocol, whichever comes first. Patients who have not progressed and are unable to undergo surgery, or who accepted R1 or R2 resection, after six cycles of the surufatinib combination with serplulimab and AG regimen, will receive sulfatinib combined with serplulimab maintenance therapy for a maximum of 29 cycles, or until intolerance, disease progression, death, or other criteria specified in the study protocol were met.
