Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
FOLFIRINOX (leucovorin, 5-flurouracil, irinotecan, oxaliplatin) became a standard of care systemic therapy option in metastatic PDAC, largely based on the findings from the Phase III ACCORD 11 study, where the objective response rate (ORR) was significantly higher with FOLFIRINOX vs single-agent gemcitabine (32% vs 9%). Median progression-free survival (PFS) (6.4 months vs 3.3 months) and overall survival (OS) (11.1 months vs 6.8 months) were higher as well. However, a recent Phase I/II study demonstrated tolerability of the chemotherapy combination liposomal irinotecan, oxaliplatin, 5-fluorouracil, and leucovorin (NALIRIFOX) in locally advanced and metastatic PDAC. This has been followed by a randomized Phase III study evaluating first-line NALIRIFOX vs gemcitabine plus nab-paclitaxel, which has demonstrated greater ORR with NALIRIFOX than gemcitabine plus nab-paclitaxel (41.8% vs 36.2%). Both median PFS (7.4 months vs 5.6 months) and OS (11.1 months vs 9.2 months) were significantly higher with NALIRIFOX than with gemcitabine plus nab-paclitaxel as well. In light of these findings, NALIRIFOX use in treatment-naïve patients is increasing.
As suggested above, gemcitabine combinations have elicited treatment responses in advanced PDAC as well. Efficacy of first-line gemcitabine plus nab-paclitaxel was demonstrated in the MPACT trial, where a higher ORR and median OS was noted in the combination arm vs single-agent gemcitabine (23% vs 7% and 8.7 months vs 6.7 months, respectively). This led to its indication for use in metastatic and locally advanced PDAC. Additionally, gemcitabine plus cisplatin was noted to have an ORR of 74% in germline BRCA1/2 and PALB2 mutated advanced PDAC. A recent small Phase II study demonstrated the use of the triplet regimen, gemcitabine plus nab-paclitaxel plus cisplatin administered on Day 1 and Day 8 of a 21-day cycle as having clinical activity in metastatic PDAC where ORR was 71% with median PFS and median OS of 10.1 months and 16.4 months, respectively. However, it remains unknown whether this triplet regimen is more efficacious than NALIRIFOX.
Therefore, investigators propose evaluating whether gemcitabine plus nab-paclitaxel plus cisplatin (mGAP) will lead to greater ORR than NALIRIFOX in previously untreated patients with locally advanced and metastatic PDAC. Of note, despite the high ORR observed with this regimen, 2 of 3 deaths in the study were attributed by the authors to the chemotherapy combination. Due to this toxicity, rather than administering the triplet regimen on Day 1 and Day 8 of a 21-day cycle as done in the Phase Ib/II study, investigators will proceed with Day 1 and Day 15 administration of a 28-day cycle. Investigators hypothesize that gemcitabine plus nab-paclitaxel plus cisplatin will have a greater ORR than NALIRIFOX and lead to improved secondary outcome measurements of BOR, DOR, DCR, PFS, OS, and toxicity profile. Investigators will determine its clinical utility relative to NALIRIFOX in the first-line setting based on standard radiology used to measure treatment response. Findings from this study may have implications for changing the standard of care systemic therapeutic approach in patients with treatment-naïve locally advanced and metastatic PDAC.
