The purpose of this study is to combine standard radiation therapy with drugs that encourages the body's immune system against cancer cells and simultaneously adding drugs which also target the pathway that the tumor uses to evade the immune system (CD73 and A2a/b). The study hopes that these drugs will work in concert with radiation therapy to kill cancer cells. The specific goal of this study is to ensure that treatment with zimberelimab and stereotactic body radiation therapy (SBRT) alone or in combination with quemliclustat (a drug which blocks CD73), with or without etrumadenant (a drug which blocks the A2a/b) given before surgery is safe and if it can further increase the immune response against the tumor.
The overall objective of this study is to combine standard radiation therapy with drugs that stimulate the body's immune system against cancer cells (by targeting the protein programmed cell death (PD-1), while adding drugs which also target the pathway that the tumor uses to evade the immune system (the CD73 and A2a/b pathways).The main goal of this study is to find out if study treatment with zimberelimab (an antibody which binds the protein PD-1) and stereotactic body radiation therapy (SBRT) alone or in combination with quemliclustat (a drug which blocks CD73), with or without etrumadenant…
Inclusion Criteria: * Histological or pathological confirmation of pancreatic adenocarcinoma Cytologic or histologic proof of pancreatic ductal adenocarcinoma (PDAC) needs to be verified by the treating institution pathologist. A pathological report from non-treating institutions is sufficient to consent and to initiate investigational therapy if tissue sample is unavailable for evaluation at time of consent or enrollment. However, in such a case, PDAC diagnosis should be confirmed by the treating institution pathologist at a later time. * Completed 8 cycles of neoadjuvant modified FOLFIRINOX…
