Nalirinox Neo-pancreas RAS Mut ctDNA Study

Study Overview
=================
Brief Summary
-----------------
Pancreatic cancer has an unfavorable prognosis with a reduced possibility of long-term survival. The only treatment with curative potential is surgery, but it is only possible in 15-20% of cases. There are patients with clear criteria for surgical entry, others at the limit of the possibility of surgery, and patients with such advanced disease (either locally or with metastasis) that surgery is not indicated. The objective of neoadjuvant chemotherapy treatment (received before surgery) is to reduce the tumor before surgery and reduce the risk of subsequent metastases and local recurrences, in borderline tumors or those resectable with high-risk criteria. The FOLFIRINOX scheme, composed of 5-fluorouracil / folinic acid, oxaliplatin and irinotecan, is recommended as neoadjuvant treatment, but the response is still low. This study will use a modified FOLFIRINOX (NALIRINOX) regimen with a form of irinotecan attached to liposomes that allows greater action on tumor cells. Mutations in the KRAS gene are associated with a greater growth capacity of tumor cells and are present in 90% of pancreatic cancers in advanced stages. They would be less frequent in earlier phases but little is known about the impact that chemotherapy treatment and subsequent surgery could have on the increase or decrease of these mutations, as well as their implication. The follow-up of these mutations with repeated pancreatic biopsies is not viable, but it can be monitored by simple blood samples in which the genetic material of the tumor can be analyzed.

Contraceptive methods comprise: oral contraceptives, intrauterine devices, sexual abstinence, tubal ligation, IUD, barrier methods or another contraceptive considered appropriate by the investigator. Women of childbearing potential must have a negative serum pregnancy test before study entry. Agree to participate and signed the ICF. Exclusion Criteria: Patients with metastatic disease Patients ≥ 75 years. Uncontrolled coagulopathy Patients with a contraindication to surgery (locally advanced disease or patients not amenable to pancreatic surgery due to a previous comorbidity) Patients with prior or concurrent malignant disease that required treatment with chemotherapy in the past. Previous cytotoxic therapy within 36 months for other no-cancer disease (ie arthritis rheumatoid) Known or suspected reactions to any component of the study medication (5-FU/LV, nal- IRI or oxaliplatin) or to components of similar chemical or biologic composition Concurrent participation in any other clinical trial likely to interfere with the therapeutic schedule Human immunodeficiency virus (HIV) positivity, active Hepatitis B or Hepatitis C infection. Uncontrolled illness including ongoing or active infection, symptomatic congestive heart failure, unstable angina, cardiac arrhythmia, myocardial infarction, or left ventricular ejection fraction (LVEF) < 50, among others, or psychiatric illness/social situations that would limit compliance with study requirements. Pregnant or breast-feeding women. Any medical condition that, based on investigator's criteria, places the subject at risk, makes the subject ineligible or may jeopardize protocol compliance.

Design Details

Primary Purpose: Treatment
Intervention Model: Single Group Assignment
Interventional Model Description: This study is a multicenter, single-arm, interventional, open-label, non-randomized, phase II clinical trial, to evaluate the association of KRAS mutational load and histological tumour response after chemotherapy treatment in patients with PDAC. Due to its single-arm design patients will be assigned to a single group (non-randomized) and there will be no masking (open-label).
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |

| Experimental: NALIRINOX treatment<br>Patients will be treated with NALIRINOX, a combination of three chemotherapy agents: 5- FU/LV, nal-IRI, and oxaliplatin. Treatment regimen will consist of 8 cycles of neoadjuvant NALIRINOX prior to surgery and trial duration is expected to be 24 months. | Drug: NALRINOX combination<br>* NALRINOX: combination of three chemotherapy agents: 5- FU/LV, nal-IRI, and oxaliplatin<br>|
