Unresectable Pancreatic Cancer Clinical Trial
Official title:
A Randomized, Controlled, Double Blind, Multicenter Study of Nimotuzumab Plus S1 Versus Placebo Plus S1 as Maintenance Treatment in Patients With Advanced or Metastatic Pancreatic Cancer After First-line Treatment
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.
