Summary
Brief summary (as posted)
The purpose of this study is to determine the effectiveness of combining immune therapy, pembrolizumab, with a hypomethylating agent, azacitidine, for pancreatic cancer. People who have advanced pancreatic cancer with disease progression on first-line therapy are usually treated with a second chemotherapy regimen. However, there is no single accepted chemotherapy regimen and national guidelines recommend chemotherapy or clinical trial participation. In this study, all study subjects will receive a combination of immune therapy (every 3 weeks) and a hypomethylating agent (every 4 weeks). To date, studies have shown that combining a hypomethylating agent with chemotherapy or immune therapy may benefit patients across different solid tumor types including pancreatic cancer. Preclinical data in a mouse model of pancreatic cancer demonstrates improvement in survival with the combination of a hypomethylating agent and immune therapy. However, the use of single agent hypomethylating agent or immune therapy has not been shown to be effective in patients with pancreatic cancer. The one exception, to date, is the use of immune therapy in those individuals with a particular genetic feature known as mismatch repair deficiency and microsatellite instability. The combination of immune therapy and a hypomethylating agent has not been studied in human subjects and is not approved by the FDA for use in pancreatic cancer. This is a non-randomized, single-center, open-label trial of pembrolizumab and azacitidine in subjects with locally advanced or metastatic pancreatic adenocarcinoma. Approximately 31 individuals will be asked to participate in this study.

Primary outcomes (1)
- measure
- Progression-Free Survival (PFS)
- timeFrame
- 24 months
- description
- 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.

Inclusion Criteria: * Be willing and able to provide written informed consent for the trial. * Age ≥18 years of age on day of signing informed consent. * Have confirmed diagnosis of pancreatic ductal adenocarcinoma * Have a predicted life expectancy of greater than 3 months. * Have measurable disease based on RECIST 1.1. * Have a performance status of 0 or 1 using the Eastern Cooperative Oncology Group (ECOG) Performance Scale within 3 days of first dose of study drug. * Have documented radiographic progression to or documented intolerance of first line systemic chemotherapy which included either gemcitabine or Fluorouracil (5-FU) based regimen (including capecitabine). * Subjects who have documented disease recurrence within 6 months of completing neoadjuvant or adjuvant chemotherapy for limited disease will be eligible for study. Subjects who recur greater than 6 months after completing adjuvant or neoadjuvant chemotherapy will not be eligible unless they receive additional chemotherapy for advanced disease. Exclusion Criteria: * Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy, or herbal/complementary oral or IV medicine within 2 weeks of the first dose of treatment. * Has received chemotherapy or radiotherapy within 14 days of first dose of study medication.
