| Title: | Nomogram for predicting overall survival (OS) in patients (pts) treated with liposomal irinotecan (nal-IRI) +/- 5-fluorouracil/leucovorin (5-FU/LV) in metastatic pancreatic ductal adenocarcinoma (mPDAC) previously treated with gemcitabine-based therapy in NAPOLI-1. |

| Abstract: | Background: Results from NAPOLI-1 (NCT01494506), a phase 3 study in pts with mPDAC previously treated with gemcitabine-based therapy, demonstrated an improvement in OS (primary endpoint), progression-free survival, and objective response rate with nal-IRI+5-FU/LV vs 5-FU/LV. The MPACT study reported a nomogram to predict OS using baseline pt variables in previously untreated mPDAC. We conducted an exploratory post hoc analysis of NAPOLI-1 variables to develop a nomogram to predict OS in the post-gemcitabine setting. Methods: In NAPOLI-1, pts were randomized to receive nal-IRI 80 mg/m2 q2w + 5-FU/LV, nal-IRI 100 mg/m2 q3w, or 5-FU/LV. Univariate and multivariate analyses determined factors significantly predictive of OS. A multivariable Cox model was created using these factors to develop a nomogram that assigned points equal to the weighted sum of relative significance of each variable. Predictive accuracy of the nomogram as measured by the concordance index (c-index) was evaluated by internal bootstrap validation. Results: Data from the 417-pt univariate analysis and 399-pt multivariate analysis (18 pts excluded for missing baseline data) were used. Eight of 21 variables were retained in the multivariate analysis (p < 0.01 except BMI [p=0.08]). Conclusions: In NAPOLI-1, predictors of OS were nal-IRI+5-FU/LV treatment, KPS, NLR, albumin level, baseline CA19-9, stage 4 at diagnosis, BMI, and presence of liver metastasis. The nomogram, which will distinguish between risk groups and may aid in clinical decision making, will be presented in the poster. |
