Trial Outcomes & Findings for Combination Therapy for Patients With Untreated Metastatic Pancreatic Ductal Adenocarcinoma (NCT NCT02754726)

NCT ID: NCT02754726

Last Updated: 2025-08-27

Results Overview

Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI: Complete response (CR) rate as defined by CT scan using RECIST 1.1 criteria - disappearance of all target lesions and no new sites or disease-related symptoms confirmed at least 4 weeks after initial documentation and CA 19-9 (or CA 125, or CEA if not expressers of CA 19-9) down to normal limits; Partial Response (PR), at least a 30% decrease in the sum of the diameters of target lesions; Overall Response (OR) = CR + PR. When a complete response is documented, a Positron emission tomography (PET) scan will be obtained to confirm.
