Gemcitabine and Paclitaxel Versus Gemcitabine Alone After 5-Fluorouracil, Oxaliplatin, and Irinotecan in Metastatic Pancreatic Adenocarcinoma: A Randomized Phase III PRODIGE 65-UCGI 36-GEMPAX UNICANCER Study.

GEMPAX was an open-label, randomized phase III clinical trial designed to assess the efficacy and tolerability of gemcitabine plus paclitaxel versus gemcitabine alone as second-line treatment for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) who previously received 5-fluorouracil, oxaliplatin, and irinotecan. Patients with histologically or cytologically confirmed mPDAC were randomly assigned (2:1) to receive GEMPAX (paclitaxel 80 mg/m Overall, 211 patients (median age, 64 [30-86] years; 62% male) were included. After a median study follow-up for alive patients of 13.4 versus 13.8 months in arm A versus arm B, the median OS (95% CI) was 6.4 (5.2 to 7.4) versus 5.9 months (4.6 to 6.9; hazard ratio [HR], 0.87 [0.63 to 1.20]; While GEMPAX did not meet the primary end point of OS versus gemcitabine alone in patients with mPDAC in the second-line setting, both PFS and ORR were significantly improved.
