NALIRIFOX Before Surgery for the Treatment of Borderline Resectable Pancreatic Ductal Adenocarcinoma, Nectar Trial

Официальное название

A Phase 2 Clinical Trial of Nalirifox as Neoadjuvant Treatment for Patients With Borderline Resectable Pancreatic Ductal Adenocarcinoma (Nectar Study)

Обзор

This phase II trial tests how well liposomal irinotecan, oxaliplatin, 5-fluorouracil and leucovorin (NALIRIFOX) before surgery works in treating patients with pancreatic ductal adenocarcinoma that is close to major blood vessels, but is still potentially removable by surgery (borderline resectable). Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and deoxyribonucleic acid (DNA) repair and may kill tumor cells. Liposomal irinotecan is a form of the anticancer drug irinotecan that is contained inside very tiny, fat-like particles. Liposomal irinotecan may have fewer side effects and work better than other forms of the drug. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. 5-fluorouracil, a type of antimetabolite, stops cells from making DNA and it may kill tumor cells. Leucovorin, a form of folic acid, is used to lessen the toxic effects of substances that block the action of folic acid. It is a type of chemoprotective agent and a type of chemosensitizing agent. Giving NALIRIFOX before surgery may improve the chance of successful surgery and decrease the chance of the cancer returning after surgery in patients with borderline resectable pancreatic ductal adenocarcinoma.

Подробное описание

PRIMARY OBJECTIVE:

I. To determine the antitumor efficacy of the combination of irinotecan sucrosofate (liposomal irinotecan), oxaliplatin and infusional fluorouracil (5-fluorouracil)/leucovorin calcium (leucovorin) (NALIRIFOX) in patients with borderline resectable pancreatic ductal adenocarcinoma.

SECONDARY OBJECTIVES:

I. To evaluate clinical efficacy and tolerability of the proposed treatment regimen.

II. To determine the safety of liposomal irinotecan, oxaliplatin and infusional fluorouracil in patients with borderline resectable pancreatic ductal adenocarcinoma.

EXPLORATORY OBJECTIVES:

I. To evaluate blood-based biomarkers predictive of short- and long-term outcomes.

II. To generate tumor tissue-based biomarkers predictive of short- and long-term outcomes.

OUTLINE:

Patients receive liposomal irinotecan intravenously (IV) over 90 minutes, oxaliplatin IV over 120 minutes, leucovorin IV over 30 minutes and fluorouracil IV over 48 hours on day 1 of each cycle. Cycles repeat every 14 days for 4-8 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo surgical resection 4-8 weeks after the last treatment dose. Starting 4-12 weeks after surgery, patients receive liposomal irinotecan, oxaliplatin, leucovorin, and fluorouracil for up to 4 additional cycles in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo computed tomography (CT) and blood sample collection throughout the study.

After completion of study treatment, patients are followed up within 30 days, every 3-6 months for 2 years, then every 6-12 months for up to 5 years.
