Trial Outcomes & Findings for Chemotherapy Plus Proton-chemotherapy for Locally Advanced Pancreatic Cancer (NCT NCT01683422)

NCT ID: NCT01683422

Last Updated: 2021-08-10

Results Overview

Subjects will be followed after treatment completed to determine length of survival rate. The primary study objective was 1-year overall survival (OS, failure: death due to any cause). The Kaplan-Meier method was used to estimate the one-year OS. Secondary Objectives were the frequency of serious adverse events, disease control rate and progression-free survival.

PRIMARY outcome

Timeframe: One year after treatment completed.

Population: The study enrolled 9 patients between January 2013 and March 2016, when the trial was closed due to poor accrual.

Subjects will be followed after treatment completed to determine length of survival rate. The primary study objective was 1-year overall survival (OS, failure: death due to any cause). The Kaplan-Meier method was used to estimate the one-year OS. Secondary Objectives were the frequency of serious adverse events, disease control rate and progression-free survival.
