Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase I/II study tests how well zimberelimab and quemliclustat work in combination with chemotherapy (mFOLFIRINOX) in treating patients pancreatic adenocarcinoma that may or may not be able to be removed by surgery (borderline resectable) or that has spread to nearby tissue or lymph nodes (locally advanced). Immunotherapy with monoclonal antibodies, such as zimberelimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Quemliclustat acts as a blocker for adenosine. Adenosine is a chemical produced in the body that can lead to a decrease in the immune system's response towards cancer. Quemliclustat has the potential to decrease the amount of adenosine, allowing the immune system to recognize and act against the cancer. Chemotherapy drugs, such as oxaliplatin, irinotecan, leucovorin, and fluorouracil, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy in combination with zimberelimab and quemliclustat may kill more cancer cells than chemotherapy alone.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To evaluate the safety, tolerability and resection rate (for borderline resectable pancreatic cancer \[BRPC\] cohort) or progression free survival (PFS) (for locally advanced pancreatic cancer \[LAPC\] cohort) in patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) treated with modified fluorouracil, irinotecan, leucovorin and oxaliplatin (mFOLFIRINOX), quemliclustat, and zimberelimab.

II. To evaluate development of clinically relevant pancreatic fistula (for BRPC cohort) in the post-operative period after neoadjuvant treatment with mFOLFIRINOX, quemliclustat, and zimberelimab.

SECONDARY OBJECTIVES:

I. To estimate efficacy as measured by decreases in CA 19-9 and objective response rate (ORR) by imaging (unconfirmed complete and partial responses).

II. To estimate the pathologic complete response rate (pCR) (for BRPC cohort) and overall survival (OS).

EXPLORATORY OBJECTIVES:

I. To evaluate the effects of zimberelimab, quemliclustat, and modified FOLFIRINOX (mFFX) on the tumor-stromal cells comparing pre-treatment core biopsies with operative specimens and on the effects on T cell infiltration, PD1 expression and the tumor microenvironment (TME).

II. To investigate potential serum and tumor predictive biomarkers to predict response to experimental therapy.

OUTLINE:

Patients receive zimberelimab intravenously (IV), quemliclustat IV, oxaliplatin IV, leucovorin calcium IV, and inrinotecan IV on study. Patients undergo collection of blood samples and computed tomography (CT) throughout the trial. Patients with borderline-resectable pancreatic cancer undergo collection of tissue samples. Patients with locally advanced pancreatic cancer undergo core biopsy.

Inclusion Criteria

* Male or female \>= 18 years of age and willing and able to provide informed consent
* Previously untreated cytologically or histologically confirmed pancreatic adenocarcinoma with one of the following:

* Borderline resectable disease. There are multiple definitions of borderline resectable PDAC including the MD Anderson definition and the criteria developed during the Consensus Conference sponsored by the American Hepato-Pancreato-Biliary Association, Society of Surgical Oncology, and Society for Surgery of the Alimentary Tract. Borderline resectable PDAC cases will be identified per the definition developed in the currently running inter-group pilot trial for borderline resectable pancreatic cancer (NCT01821612). Per this trial, borderline resectable PDAC is defined as the presence of any one or more of the following on CT;

* An interface between the primary tumor and the superior mesenteric vein or portal vein (SMV-PV) measuring \>= 180 degrees of the circumference of the vessel wall
* Short-segment occlusion of the SMV-PV with normal vein above and below the level of obstruction that is amenable to resection and venous reconstruction
* Short segment interface (of any degree) between tumor and hepatic artery with normal artery proximal and distal to the interface that is amenable to resection and reconstruction
* An interface between the tumor and SMA measuring \< 180 degrees of the circumference of the vessel wall
* Locally advanced disease. Multiple guidelines defining locally advanced PDAC have been developed, including the MD Anderson definition, the National Comprehensive Cancer Network (NCCN) definition, as well as the criteria developed during the Consensus Conference sponsored by the American Hepato-Pancreato-Biliary Association, Society of Surgical Oncology, and Society for Surgery of the Alimentary Tract. Locally advanced PDAC cases will be identified per the definition developed by the Alliance for Clinical Trials in Oncology. Per this definition, locally advanced PDAC is defined as presence of any one or more of the following on CT;

* Occlusion of the SMV-PV that is not amenable to resection and venous reconstruction
* Interface between tumor and hepatic artery that is not amenable to resection and reconstruction
* Interface between the tumor and SMA measuring \> 180 degrees of the circumference of the vessel wall
* Interface between the tumor and celiac axis measuring \> 180 degrees of the circumference of the vessel wall
* Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
* Absolute neutrophil count (ANC) \>= 1.5 x 10\^9/L
* Platelets \>= 100 x 10\^9/L
* Hemoglobin \>= 9 g/dL
* Serum creatinine (sCr) =\< 1.5 x upper limit of normal (ULN) or Creatinine clearance (Ccr) \>= 40 mL/min (as calculated by Modified Cockcroft-Gault formula)
* Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase (AST/\[SGOT\]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 X ULN
* Women with no childbearing potential because of surgery or who are at least 1 year postmenopausal (ie, 12 months post last menstrual period) or with menopause confirmed by follicle-stimulating hormone testing

* Male participants must use an effective method of contraception (condom or occlusive cap \[diaphragm or cervical or vault caps\] with spermicidal foam or gel or film or cream or suppository, or vasectomy) throughout the study and for up to 6 months after the last dose of zimberelimab or quemliclustat
* Immunosuppressive doses of systemic medications, such as corticosteroids or absorbed topical corticosteroids (doses \> 10 mg/day prednisone or equivalent) must be discontinued at least 2 weeks (14 days) before study treatment administration. Physiologic doses of corticosteroids (=\< 10 mg/day of prednisone or its equivalent) or short pulses of corticosteroids (=\< 3 days) may be permitted
* Prior surgery that required general anesthesia or other major surgery as defined by the Investigator must be completed at least 4 weeks before study treatment administration. Surgery requiring regional/epidural anesthesia must be completed at least 72 hours before study treatment administration. Participants should have recovered from the surgical procedure prior to the first dose being administered
