Study of Pembrolizumab With or Without Defactinib Following Chemotherapy as a Neoadjuvant and Adjuvant Treatment for Resectable Pancreatic Ductal Adenocarcinoma

Phase 2
Active, not recruiting
Conditions
Resectable Pancreatic Ductal Adenocarcinoma (PDAC)
Pancreatic Ductal Adenocarcinoma
Interventions
Registration Number
NCT03727880
Lead Sponsor
The University of Texas Health Science Center at San Antonio
Brief Summary

This study will test the effectiveness (anti-tumor activity), safety, and ability to increase the body's immune system to fight pancreatic cancer by combining standard chemotherapy before and after surgery, with study drug PD-1 antibody, pembrolizumab, with and without study drug, focal adhesion kinase inhibitor (FAK), defactinib, in people with "high risk" resectable (surgically removable) pancreatic cancer. The purpose of this study is to evaluate if reprograming the tumor microenvironment by targeting FAK following chemotherapy can potentiate anti-programmed death-1 (PD-1) antibody.

Primary Outcome Measures
NameTimeMethod
Pathologic complete response (pCR) rate4 years

Percent of subjects with a pathologic complete response (pCR) per the tumor regression grade scores established by the College of American Pathologist: Grade 0= complete response (no viable cancer cells), Grade 1= near complete response (single cells or rare small groups of cancer cells), Grade 2= partial response (residual tumor with evidence of regression), or Grade 3= no response (extensive residual tumor with no evidence of regression).
