Trial Outcomes & Findings for Arginase-1 Peptide Vaccine in Patients With Metastatic Solid Tumors (NCT NCT03689192)

NCT ID: NCT03689192

Last Updated: 2023-02-28

Results Overview

Patients were evaluated according to Common Terminology Criteria for Adverse Events (CTCEA). An adverse event (AE) is an abnormal clinical finding. Each participant was assessed from start of treatment until 6 months after the last vaccine.

SECONDARY outcome

Timeframe: project blood samples were taken at baseline and every 3 months for a maximum of 1,5 year. Tumor biopsies were taken at baseline and after 3 months if possible.

Population: Development of a reactive T cell response against at least one of the ARG1 peptides during treatment using interferon-gamma ELISPOT

To evaluate the immunological impact of the ARG1-18,19,20 peptide vaccines using blood samples and tumor biopsies.

SECONDARY outcome

Timeframe: 0 - 75 weeks

Overall Survival (OS) defined as time from treatment initiation to death, will be described with use of Kaplan Meier curve.

Interval 4.5 to 18.8

SECONDARY outcome

Timeframe: 0 - 75 weeks

Progression free survival (PFS) defined as the time from treatment initiation to disease progression, relapse or death due to any cause, which ever comes first, will be described with Kaplan Meier curve. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), 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.
