PDAC - Pancreatic Ductal Adenocarcinoma
Conditions
Brief summary
The main objective of PANORAMIX phase II trial is to optimize first-lie (L1) NALIRIFOX treatment for pancreatic cancer through the implementation of 5-fluorouracil (5-FU) maintenance therapy. Additionally, it aims to investigate the role of antibiotics and microbiota in second-line (L2) treatment.
Detailed description
This randomized non-comparative phase II study consists of two sequential steps. Step 1 (main objective), the primary goal is to assess the efficacy of a maintenance strategy with LV5FU2 alone after disease control with first-line NALIRIFOX-based chemotherapy in patients with metastatic pancreatic ductal adenocarcinoma (PDAC). Step 2 of the study (exploratory objective), aim is to assess the efficacy and safety of the addition of fluoroquinolone (ciprofloxacin) to gemcitabine-based chemotherapy in second-line setting.
Interventions
NAL-IRI 50 mg/m2, administered over 80-100 minutes, on day 1 of a 14-days cycle

80 mg/m2 weekly on days 1, 8, 15 of each 28-days cycle (at the discretion of investigator)
1,000 mg/m2 intravenously (IV) over 30 minutes weekly on days 1, 8, 15 of each 28-days cycle

As part of NALIRIFOX -for 8 cycle treatment: (L + D racemic form) 400 mg/m2 on day 1 (equivalent to 200 mg/m2 levoleucovorin) (starting 30 minutes after oxaliplatin, administered over 25-35 minutes) As part of LV5FU2 maintenance treatment: 400 mg/m2 IV infusion over 30 min on day 1 (equivalent to 200 mg/m2 levoleucovorin). LV could be administered over 2 hours to oxaliplatin according to The National Thesaurus of Digestive Oncology (TNCD) https://www.snfge.org/sites/www.snfge.org/files/tncd/2024-05/tncd\_chap-09-cancer-pancre%CC%81as\_2024-05-17\_1.pdf, at investigator's discretion

6 capsules/cycle : 500 mg twice daily (morning and evening; 12 hours should elapse between two doses) on days 1, 8, 15 (on day of gemcitabine infusion) for a maximum of 6 months

Intervention model description
This is a randomized, non-comparative two-step study in patients with metastatic PDAC. STEP 1 (main objective) This is a two-arm, open-label, randomized (2:1), non-comparative single stage phase II study to assess the efficacy of 5-FU-based maintenance after NALIRIFOX initiation (Arm 1A) versus standard NALIRIFOX in patients with metastatic PDAC (Arm 1B). STEP 2 (secondary exploratory objective) This is a two-arm, double-blinded, randomized (1:1), non-comparative, two-stage phase II with ciprofloxacin + gemcitabine-based chemotherapy (gemcitabine +/- paclitaxel) regimen (Arm 2A) versus gemcitabine-based chemotherapy (gemcitabine +/- paclitaxel) regimen + placebo (Arm 2B)
