Trial Outcomes & Findings for Azacitidine and Pembrolizumab in Pancreatic Cancer (NCT NCT03264404)

NCT ID: NCT03264404

Last Updated: 2026-01-27

Results Overview

PFS is defined as the time from the first day of trial treatment to the first documented disease progression per RECIST 1.1 (At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression)) or death due to any cause, whichever occurs first.

Interval 1.38 to 1.74

SECONDARY outcome

Timeframe: Throughout study duration, up to approx 80 months

ORR is defined as the percentage of the participants in the analysis population who have a complete response (CR) or partial response (PR). Responses are based on assessments per RECIST 1.1.

Objective Response Rate (ORR)
9.7 percentage of participants

SECONDARY outcome

Timeframe: Throughout study duration, up to approx 80 months

Population: 3 participants had a complete or partial response to treatment, so this outcome measure was assessed in those 3 patients only.

For subjects who demonstrate CR or PR, based on assessments per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first.
