    摘要: Background: Chemotherapy dose modifications to manage adverse events (AEs) is common in clinical practice. In NAPOLI-1 (NCT01494506), a randomized phase 3 study in patients with metastatic pancreatic cancer previously treated with gemcitabine-based therapy, nal-IRI+5-FU/LV improved overall survival (OS; primary endpoint) vs 5-FU/LV (6.1 mos vs 4.2 mos; HR = 0·67, 95% CI 0.49–0.92; P = 0.012). The study protocol permitted dose modifications (reduction or delay) to address toxicity. In this exploratory post-hoc analysis, we evaluated the impact of nalIRI dose modifications on overall survival (OS) and progression-free survival (PFS). Methods: All pts enrolled under protocol v2 who received nal-IRI+5-FU/LV during the first 6 wks were included in the analysis. Pts were grouped according to those with dose modification or those without dose modification. Dose reduction was defined as any decrease from initial dose, delay as any dosing delay >3 days from target date. Pts without dose modification received the first 3 scheduled doses of nal-IRI+5-FU/LV without qualifying delay/reduction. OS and PFS (KaplanMeier estimates) were compared within the nal-IRI+5-FU/LV arm. Unstratified hazard ratios (HRs) were calculated using Cox regression. Results: Among pts in the nal-IRI+5-FU/LV arm (n = 93), 40 pts had no dose modification and 53 had a dose modification (delay, n = 49; reduction, n = 34). Within the nal-IRI+5-FU/LV arm, there was no significant difference in median OS or PFS between pts with vs without dose modification (Table). Conclusions: Dose modification of nal-IRI+5-FU/LV in the first 6 wks does not significantly impact OS or PFS compared to patients without dose modifications. This suggests that tolerability-guided dose modification of nal-IRI does not adversely affect efficacy outcomes.
