Clinical Trial Summary

This is a multi-center, open-label， randomized controlled Phase II clinical study to observe and evaluate the efficacy and safety of Penpulimab combined with Anlotinib and Nab-paclitaxel plus Gemcitabine (PAAG ) versus AG first-line treatment in patients with metastatic pancreatic cancer.

Description:

This study is a multi-center, open-label, randomized controlled Phase II clinical study to evaluate the efficacy and safety of penpulimab in combination with anlotinib and AG regimen in the first-line treatment of advanced metastatic pancreatic cancer, and to explore the clinical indicators related to efficacy to guide the individualized treatment.

Trial group:

Nab-paclitaxel 125mg/m2 I.V. D1,8 Gemcitabine 1.0g/m2 I.V. D1,8 Penpulimab 200mg IV D1 Anlotinib 12mg/10mg P.O. QD D1-14 (12mg for body surface area ≥1.6m2, 10mg for body surface area ≤1.6m2)

Control group:

Nab-paclitaxel 125mg/m2 I.V. D1,8 Gemcitabine 1.0g/m2 I.V. D1,8

1 cycle every 21 days Efficacy assessments will be performed every 2 cycles for the first 8 cycles of treatment. If treatment exceeds 8 cycles (24 weeks) in the trial group, maintenance therapy with anlotinib + PD1 and efficacy assessment every 2 cycles; in the control group, efficacy assessment every 2 cycles. Patient with disease control (CR+PR+SD) and tolerable adverse events were continued on the drug until discontinuation of the drug if efficacy was evaluated as disease progression (PD), if an intolerable adverse event occurred, or if the investigator deemed it unsuitable for the patient to continue on the treatment.

Efficacy Indicators Primary endpoint: median progression-free survival (mPFS) Secondary endpoint: objective response rate (ORR), disease control rate (DCR), median overall survival (mOS), safety; potential biological indicators for predicting efficacy (tumor tissue NGS assay, ctDNA, mRNA, and various immune cytokines in peripheral blood, etc.)

Safety evaluation indexes:

Observe the presence or absence of clinical adverse events such as myelosuppression, nausea, vomiting, liver damage, skin reactions (e.g., rash), pneumonitis, hypertension, proteinuria, fatigue, and nausea, etc., which are graded according to NCI criteria.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free survival(PFS)	Progression-free Survival (PFS) (median) was determined using the number of months measured from the initial date of treatment to the date of documented progression, or the date of death (in the absence of progression) of participants. Progression is defined using RECIST v1.1, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.	up to 1 years
Secondary	Objective Response Rate (ORR)	Objective response rate is defined as the percentage of subjects whose best response was complete response (CR) or partial response (PR) according to the Response Evaluation Criteria In Solid Tumors Criteria(RECIST v1.1)	up to 1 years
Secondary	Disease Control Rate (DCR)	Disease control rate is defined as the percentage of subjects whose best response was CR, PR or stable disease (SD) according to the RECIST v1.1	up to 1 years
Secondary	Overall Survival (OS)	Overall Survival (OS) (median) is determined using the number of months measured from the initial date of treatment to the recorded date of death of participants.	up to 2 years
