Outcome Measures
Primary Outcomes (2)
Event-free survival
to compare in terms of event free survival (EFS) the efficacy of PAXG to that of mFOLFIRINOX. EFS is defined as the time from randomization to: RECIST 1.1 progression \[At least a 20 percent increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20 percent, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression\]; CA19.9 failure (defined as 2 consecutive increases of serum level ≥20 percent, separated by at least 4 weeks); recurrence; preoperative or intraoperative unresectability; intraoperative evidence of metastases; death for any cause; whichever occurs first. R1 resections will NOT be considered as events whereas R2 resections will be.
12 weeks
Event-free survival
to compare in terms of event free survival (EFS) the efficacy of 4 months pre-operative and 2 months postoperative chemotherapy to that of 6 months of pre-operative chemotherapy . EFS is defined as the time from randomization to: RECIST 1.1 progression \[At least a 20 percent increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20 percent, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression\]; CA19.9 failure (defined as 2 consecutive increases of serum level ≥20 percent, separated by at least 4 weeks); recurrence; preoperative or intraoperative unresectability; intraoperative evidence of metastases; death for any cause; whichever occurs first. R1 resections will NOT be considered as events whereas R2 resections will be.

- Active, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy, defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment
- Known infection with hepatitis B or C, or history of human immunodeficiency virus (HIV) infection, or subject receiving immunosuppressive or myelosuppressive medications that would in the opinion of the investigator, increase the risk of serious neutropenic complications

- Locally advanced disease according to NCCN Guidelines Version 1.2020 - Pancreatic Adenocarcinoma \[appendix 2\];
- Serious medical risk factors involving any of the major organ systems, or serious psychiatric disorders, which could compromise the subject's safety or the study data integrity. These include, but are not limited to:
- History of connective tissue disorders (eg, lupus, scleroderma, arteritis nodosa)
- History of interstitial lung disease, slowly progressive dyspnea and unproductive cough, sarcoidosis, silicosis, idiopathic pulmonary fibrosis, pulmonary hypersensitivity pneumonitis or multiple allergies

- Any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study
- Any condition including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study
- Any condition that confounds the ability to interpret data from the study
- Any familiar, sociologic or geographic conditions that can potentially interfere with the adhesion to the protocol or to the follow-up;
