Brief summary

The main purpose of this research study is to determine the maximum tolerable dose (MTD) of SX-682 in combination with nivolumab in patients with metastatic pancreatic ductal adenocarcinoma who have completed at least 16 weeks of first line chemotherapy treatment without evidence of disease progression.

Detailed description

In this study the investigator would like to better understand the maximum tolerable dose (MTD) of SX-682 in combination with nivolumab in patients with metastatic pancreatic ductal adenocarcinoma who have completed at least 16 weeks of first line chemotherapy treatment without evidence of disease progression. In addition, the investigator would like to measure the SX-682 pharmacokinetic data in humans. The investigator would also like to assess the immunophenotypic and stromal changes to the tumor microenvironment after treatment.

Inclusion criteria

Written Informed Consent and HIPAA Authorization 1. Subjects must have the nature of the study explained to them 2. Subjects must be willing and able to comply with scheduled visits, treatment schedule, laboratory tests, pharmacokinetic collections, study biopsies and other requirements of the study. 3. Subjects (or an acceptable proxy) must provide a signed and dated IRB/IEC approved written informed consent form (ICF) in accordance with regulatory and institutional guidelines for both the study and exploratory biomarker analysis obtained via paired biopsies. 4. Subjects (or an acceptable proxy) must provide a signed and dated Health Insurance Portability and Accountability Act (HIPAA) authorization. 5. The ICF and HIPAA authorization must be obtained before conduction and procedures that do not form a part of the subject's normal care. 6. After signing the ICF and HIPAA Authorization, subjects will be evaluated for study eligibility during the Screening Period (no more than 28 days before study drug administration) according to the following further inclusion/
