A Single-center, Prospective, Two Cohort Study of Surufatinib Combined With AG or AG in the First-line Treatment of Locally Advanced or Metastatic Pancreatic Cancer

A Single-center, Prospective, Two Cohort Study of Surufatinib Combined With Gemcitabine and Nab-paclitaxel or Gemcitabine Combined With Nab-paclitaxel in the First-line Treatment of Locally Advanced or Metastatic Pancreatic Cancer

This is a single-center, prospective, two cohort study to evaluate the efficacy and safety of surufatinib in combination with AG or AG alone in the first-line treatment of patients with locally advanced or metastatic pancreatic cancer.

Participants with previously received AG chemotherapy for 2 cycles with no disease progression will be enrolled:

Arm 1: Surufatinib plus AG chemotherapy (q3w) until disease progression/death/withdrawn; Arm 2: AG chemotherapy (q3w) until disease progression/death/withdrawn;

During the treatment period, imaging methods were used to evaluate the tumor status every 6 weeks (±7 days) until disease progression (RECIST 1.1) or death (during the patient's treatment) or toxicity was intolerable or other criteria for termination of study treatment specified in the protocol were met, and the tumor treatment and survival status after disease progression were recorded. Safety observation indicators include: AEs, changes in laboratory values, vital signs, and changes in electrocardiogram.

Study Overview

• Status: Recruiting
• Conditions: Pancreatic Cancer Metastatic
• Intervention / Treatment: Drug: Surufatinib, gemcitabine, nab-paclitaxel; Drug: Nab-paclitaxel, gemcitabine

Detailed Description

This is a single-center, open-label randomized controlled Phase II clinical study to observe and evaluate the efficacy and safety of solantinib combined with AG versus AG first-line therapy in patients with locally advanced or metastatic pancreatic cancer.

According to the literature analysis, the mPFS of gemcitabine combined with albumin-bound paclitaxel in first-line treatment of metastatic pancreatic cancer in historical control studies was 3.56 months, and the PFS of solantinib combined with AG regimen was expected to increase from 2.06 months to 4.5 months after 2 cycles of AG regimen. Follow-up time was 12 months and enrollment time was 18 months. α=0.05 and β=0.2 were used for bilateral test, and PASS 22 software was used for analysis. The sample size of AG group in the control group was 29 cases, and that of AG combined with solvatinib in the experimental group was 29 cases. The total sample size required to be enrolled was 58 cases, and a total of 65 subjects were required according to the calculation of 10% shedding rate.

The study was divided into three stages: screening period, treatment period and follow-up period. During treatment, the tumor was evaluated by imaging every 6 weeks (±7 days) until disease progression (PD, RECIST 1.1) or death (during the patient's treatment) or toxicity became intolerable or other protocol criteria for discontinuation of study therapy were met. It is specified that AG chemotherapy should not exceed a maximum of 8 treatment cycles, and that solantinib should be continued until disease progression (PD, RECIST 1.1) or death (in the course of patient treatment) or toxicity becomes intolerable or other criteria for discontinuation of study therapy as specified in the protocol are met. The tumor treatment and survival status after disease progression were recorded. Safety outcome measures included AE, changes in laboratory test values, vital signs and electrocardiogram changes.

Researchers can add unplanned imaging tests for tumors as clinically necessary.

What is the study measuring?

Outcome Measure	Time Frame

Secondary Outcome Measures

Outcome Measure	Time Frame
Objective Response Rate	The proportion of patients whose tumors have decreased by a certain degree and remained so for a specified duration, including cases of complete response (CR) and partial response (PR). Tumor objective response is assessed using RECIST v1.1
Overall survival	Overall survival (OS) refers to the duration from the date of enrollment to the date of death due to any cause.
Disease control rate	Defined as the proportion of evaluable patients with complete response (CR), partial response (PR), or stable disease (SD) as confirmed cases. At baseline, subjects must have measurable tumor lesions; responses are evaluated according to RECIST v1.1
