A Neoadjuvant Study of Tislelizumab and SX-682 for Resectable Pancreas Cancer
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety and clinical activity of tadalafil, pembrolizumab, ipilimumab, and CRS-207 in subjects with metastatic pancreatic adenocarcinoma who have progressed after at least 1 prior chemotherapy regimen.

Experimental: Arm A - Tislelizumab and SX-682

Drug: Tislelizumab
Patients will receive Tislelizumab (200 mg intravenous) on Day 1 of Cycles 1-6. Cycle 1 will be 14 days long and occur prior to surgery. Cycle 2 will be 14 days long and occur prior to standard of care chemotherapy. Cycles 3-6 will each be 21 days long and will be given after completion of standard of care chemotherapy.
Other Names:
Drug: SX-682
Patients will receive SX-682 (200 mg twice daily by mouth) on Days 1-14 of Cycles 1-2 and Days 1-21 of Cycles 3-6. Cycle 1 will be 14 days long and occur prior to surgery. Cycle 2 will be 14 days long and occur prior to standard of care chemotherapy. Cycles 3-6 will each be 21 days long and will be given after completion of standard of care chemotherapy.

Outcome Measures
Primary Outcome Measures
- Change in Immune response rate as assessed by density of intratumoral granzyme B+ CD137+ T cells [Baseline and 2 weeks]
The change in density of intratumoral granzyme B+ CD137+ T cells before and after neoadjuvant treatment with tislelizumab and SX-682.
- Pathologic Response Rate as assessed by number of patients with a grade 0-2 pathologic response [4 years]
The number of patients with a grade 0-2 pathologic response as defined by the College of American Pathologists (CAP) tumor regression grading system.
Secondary Outcome Measures
- Number of participants experiencing grade 3 or above drug-related toxicities [4 years]
When calculating the incidence of AEs, each AE (as defined by NCI CTCAE v5.0) will be counted only once for a given subject.
- Overall Survival (OS) [4 years]
OS is defined as the time from the first dose of study treatment to death from any cause. Patients who have not died will be censored at the last date known to be alive. Estimation based on the Kaplan-Meier curve.
- Disease Free Survival (DFS) [4 years]
DFS is defined as the time from the first dose of study treatment until evidence of disease recurrence or death from any cause. For patients who have not progressed, relapsed, or died at the time of analysis, DFS will be censored on the date of last visit where disease progression was evaluable. Estimation based on the Kaplan-Meier curve.
