Nimotuzumab Plus S1 Versus Placebo Plus S1 as Maintenance Treatment in Patients With Unresectable Pancreatic Cancer

Phase 4

• Conditions: Unresectable Pancreatic Cancer
• Interventions: Drug: Nimotuzumab plus S1; Drug: Placebo plus S1

• Registration Number: NCT02945267
• Lead Sponsor: Chinese PLA General Hospital

Brief Summary

Background: Monotherapy with S-1, oral fluoropyrimidine, shows non-inferiority to gemcitabine in overall survival (OS) with good tolerability for advanced pancreatic cancer in Asian patients. It is also shown that nimotuzumab plus gemcitabine could improve OS and progression free survival (PFS) in patients with unresectable pancreatic cancer. However, it is still unknown whether nimotuzumab plus S1 would improve more to OS and PFS than single S-1. Maintenance treatment, as a new treatment pattern, has also been tried in these patients after first line treatment to improve the OS. Thus, this study is designed to compare nimotuzumab plus S1 to placebo plus S1 as maintenance treatment in patients with locally advanced or metastatic pancreatic cancer who has benefited from the first-line treatment of gemcitabine combined with nimotuzumab and S1 (complete response+partial response+stable disease).

Patients and methods: 60 patients will be enrolled,and randomized in a 1:1 ratio to group nimotuzumab plus S1 and group placebo plus S1. nimotuzumab/placebo: 400 mg/w, intravenous infusion, Infusion time ≥ 60 min, d1, once every two weeks. S1: oral, 40 mg (Body surface area\<1.5 m2) or 60 mg (Body surface area\>1.5 m2), d1-d14, every three weeks for a cycle. Treatment interventions will be stopped under the conditions of disease progression or intolerable toxic reaction or participants ask to quit. The primary endpoint is the time to disease progression since randomization (TTP), secondary points include OS, 3 years overall survival rate (OSR) and safety.
