- Primary Endpoint
- STEP 1 The 6-month PFS post R1 in patients with L1 NALIRIFOX followed by LV5FU2 (5-FU/LV) in Arm 1A defined by the number of patients free of radiological progression or death at 6 post R1 divided by the total number of patients assessable for the PFS status at 6 months.
Study Overview
Brief Summary
- Step1 : To assess the efficacy of NALIRIFOX with LV5FU2 (5-FU/LV) maintenance strategy in patients with metastatic PDAC who received L1 in terms of 6-month PFS rate post first randomization (R1) during Step 1 (Arm 1A).
- Step2 : The primary objective of Step 2 of the study is to assess the efficacy of adding fluoroquinolone (ciprofloxacin) to gemcitabine-based chemotherapy in L2 in terms of rate of patients alive at 6 months following second randomization (R2) in Arm 2A.
