NAPOLI-1 (NCT01494506) was a phase III study of liposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) previously treated with gemcitabine-based therapy. This post hoc analysis of NAPOLI-1 aimed to develop a predictive nomogram for overall survival (OS) at 6 and 12 months. Analyses were derived from all patients in NAPOLI-1 randomized to receive nal-IRI+5-FU/LV, nal-IRI monotherapy, or 5-FU/LV combination therapy. OS was associated with baseline factors using univariate and multivariable Cox analyses. A predictive nomogram was derived and validated using a concordance index and calibration plots. The univariate analyses identified 21 independent factors that contributed to OS, with eight factors significantly associated with OS. The Karnofsky Performance Score contributed the largest number of points (100), followed by presence of liver metastasis (98) and randomization to nal-IRI+5-FU/LV (96). The other baseline factors showing effects were albumin (g/dL), neutrophil/lymphocyte ratio, carbohydrate antigen 19-9 (U/mL), disease stage at diagnosis, and body mass index (kg/m2). The nomogram was used to predict the 6- and 12-month survival probability. The mean absolute errors between the observed and predicted probabilities for OS at 3, 6, and 9 months were 0.07, 0.08, and 0.07, respectively. This nomogram, based on NAPOLI-1, provides additional insight to aid decision-making for patients with mPDAC after previous gemcitabine-based therapy.

460 Background: We report a post hoc, exploratory analysis of pts with BL ML number and LL data who received nal-IRI+5-FU/LV, nal-IRI or 5-FU/LV in NAPOLI-1, a pivotal, phase 3 trial (NCT01494506). nal-IRI+5-FU/LV increased median OS (mOS) vs 5-FU/LV (6.1 vs 4.2 mo [HR=0.67; p=0.012]). Methods: ML (1, 2, 3, >3) and LL were recorded (local investigator) at BL. Pts with >1 LL were counted for each location. Results: 354 of 417 ITT pts had measurable BL ML and 1,080 LL were recorded. There was no clear trend in the percentage of pts with KPS ≥80 in 1- >3 ML (range 87%-95%) or LL (range 89%-94%) subgroups. ML 1 (n=81), 2 (n=65) and 3 (n=24) subgroups were small. nal-IRI+5-FU/LV significantly improved mOS vs. 5-FU/LV in pts with 2/>3 ML (n=184/24); nal-IRI+5-FU/LV had numerically higher mOS vs. 5-FU/LV for all LL (Table). nal-IRI+5-FU/LV had favourable median PFS (mPFS) vs. 5-FU/LV in pts with 1–>3 ML (range 2.0-4.2 vs. 1.4-1.9 mo; HR range 0.35-0.88) and for all LL (range 2.8-4.2 vs. 1.4-2.0 mo; HR range 0.39-0.55). Conclusions: Low pt numbers across groups and repeat counting of pts in LL subgroups preclude firm conclusions on treatment efficacy, pending further analyses. Allowing for these limitations, we detected no clear prognostic effect on outcomes of higher BL ML number or LL in NAPOLI-1 ITT pts. nal-IRI+5-FU/LV improved mOS vs. 5-FU/LV in some ML groups and across LL groups; improvement in mPFS vs. 5-FU/LV in the ITT population was maintained in all subgroups.

379 Background: We report an exploratory, post hoc subgroup analysis in pts with BPI and BAU data receiving nal-IRI+5-FU/LV, nal-IRI or 5-FU/LV in NAPOLI-1 (NCT01494506). In this pivotal trial, nal-IRI+5-FU/LV improved median OS (mOS) vs. 5-FU/LV (6.1 vs. 4.2 mo [HR=0.67; p=0.012]). Methods: BPI/BAU included an average of 3-7 days pt-recorded data before randomisation. Greater values indicated greater pain for BPI using a 100 mm visual analogue scale. BAU was converted to morphine equivalent mg/day. Results: Of 417 ITT pts, 295 had BPI and 299 had BAU data. Mean and median BPI were 28.6 and 25.0, respectively, and BAU were 33.3 and 8.1 mg/day, respectively. The percentage of pts with KPS ≥ 80 was higher in ≤ mean/≤ median (n=159/148) BPI groups vs. > mean/> median (n=136/147) BPI groups (96-97 vs. 83%) and in ≤mean/≤median (n=207/150) BAU groups vs. > mean/> median (n=92/149) BAU groups (95-97 vs. 82-85%). mOS and median PFS (mPFS) were higher for nal-IRI+5-FU/LV vs 5-FU/LV in all groups, with ≤ mean/≤ median BPI or BAU showing better outcomes vs. > mean/> median BPI or BAU (Table). Conclusions: BPI and BAU appear to have a prognostic effect on outcomes in mPDAC pts in the NAPOLI-1 study. No predictive effect was observed, with nal-IRI+5-FU/LV showing higher mOS vs. 5-FU/LV in all groups. Clinical trial information: NCT01494506. [Table: see text]

410 Background: We report prognostic evaluation of BL weight-associated parameters (body-mass index [BMI], body surface area [BSA] and weight) in pts with mPDAC after progression following gem-based therapy (NAPOLI-1 trial; NCT01494506). Pts received nal-IRI+5-FU/LV, nal-IRI monotherapy or 5-FU/LV in NAPOLI-1, an international, randomised, phase 3 trial; nal-IRI+5-FU/LV treatment resulted in a 45% increased median OS vs. 5-FU/LV (unstratified HR = 0.67; p = 0.012). Methods: This exploratory subgroup analysis compares outcomes by BL BMI, BSA and weight, using primary survival analysis data from the ITT population for all treatment arms combined (n = 417) and the nal-IRI+5-FU/LV arm on its own (n = 117). Results: OS and PFS were not significantly different between BL BMI, BSA and weight median subgroups in the entire NAPOLI-1 ITT population (HR range 1.06–1.15; log-rank p-value range 0.21–0.60; Table) and in the nal-IRI+5-FU/LV arm (HR range 0.94–1.19; log-rank p-value range 0.43–1.00). Conclusions: This post-hoc subgroup analysis did not detect any prognostic impact on treatment outcome by BL BMI, BSA and weight for mPDAC pts progressed following gem-based therapy. This observation rules out a treatment-independent effect. No evidence of a predictive effect on nal-IRI+5-FU/LV efficacy was found. Clinical trial information: NCT01494506. [Table: see text]

18082 Background: P is a multitargeted antifolate active in NSCLC. While a number of clinical trials have evaluated P safety and efficacy in general patient populations, little is known of the possible impact of race on the utility of P therapy in NSCLC. The objective of this post-hoc analysis was to evaluate the effect of race on the safety and efficacy of P (single-agent or in combination) in patients with locally advanced and metastatic NSCLC. Methods: Data from 6 trials with at least 5% non-Caucasian patients were pooled for analyses. One Phase III trial evaluated P in a second-line setting. All other trials used P in Phase II first-line settings. Patients were given at least one dose of P (single-agent or in combination) at 600 mg/m2 (59 patients) or 500 mg/m2 (469 patients) every 21 days. Demographic, safety, and efficacy data were stratified broadly by race, to either Caucasian or non-Caucasian groups. Kaplan-Meier method was used to estimate median survival. The Cox model was used to calculate the hazard ratio (HR) for survival, adjusting for significant prognostic factors, including disease stage, performance status, gender, and line of treatment. Results: Results are summarized in the data table below. The adjusted HR for survival (non-Caucasian versus Caucasian) was 0.89 (p=0.365). Conclusions: In this post-hoc analysis of results from clinical trials using P therapy in NSCLC, race did not have a statistically significant impact on response rate, disease control rate, or survival. However, P therapy appeared to be better tolerated by non-Caucasian patients. [Table: see text] No significant financial relationships to disclose.

4127 Background: In the NAPOLI-1 study, nal-IRI+5-FU/LV significantly increased median OS vs. 5-FU/LV control (6.1 vs. 4.2 mo; unstratified HR = 0.67 [0.49–0.92]; p = .012). This is a subgroup analysis by prior lines of mtx. Methods: Study methodology has been published (Wang-Gillam; Lancet 2016). This exploratory subgroup analysis compares outcomes in pts with 0–1 vs. ≥2 prior mtx lines, based on primary survival analysis data (cut-off February 2014) of the ITT population. Results: OS, PFS and CA19-9 response rates in pts with 0–1 (65.8% of pts) or ≥2 (34.2%) prior mtx lines are shown (see Table). Median OS for nal-IRI+5-FU/LV improved vs. 5-FU/LV by 2.1 mo to 6.2 mo (HR = 0.66; p = .03) in pts with 0–1 prior mtx lines and by 1.1 mo to 5.4 mo (HR = 0.68; p = .18) in pts with ≥2 prior mtx lines. The safety profile was similar between subgroups with nal-IRI+5-FU/LV (≥grade 3 drug-related AEs: 43 [55%] with 0–1 and 20 [51%] with ≥2 prior mtx lines). Conclusions: This post-hoc subgroup analysis shows significant increases for nal-IRI+5-FU/LV over 5-FU/LV in OS, PFS and CA19-9 response in pts with 0–1 prior mtx lines. Median OS benefit was less prominent in later lines, but conclusions are restricted by limited pt numbers. Clinical trial information: NCT01494506. [Table: see text]

293 Background: nal-IRI, a liposomal formulation of irinotecan, plus 5-FU/LV is approved in the United States and Taiwan for patients (pts) with mPDAC previously treated with gemcitabine-based therapy. Primary analysis of the NAPOLI-1 trial (NCT01494506) showed that nal-IRI+5-FU/LV significantly improved median overall survival vs 5-FU/LV (6.1 vs 4.2 months; HR, 0.67; 95% CI, 0.49-0.92; P = 0.012; Wang-Gillam et al, Lancet. 2016). Herein we report baseline characteristics of pts surviving ≥1 year (data cutoff, Nov 2015). Methods: This analysis includes 117 pts assigned to treatment with nal-IRI 70 mg/m2 (free base) + 5-FU/LV 2400/400 mg/m2 q2w, and 119 pts assigned to treatment with 5-FU/LV 2000/200 mg/m2weekly for weeks 1-4 q6w. Results: A total of 29 (25%) pts in the nal-IRI+5-FU/LV arm and 17 (14%) in the 5-FU/LV arm survived ≥1 year. These pts typically had better performance status, lower CA19-9 (U/mL) levels, and were less likely to have liver metastases at baseline, compared with the overall population (Table). For long-term survivors in the nal-IRI+5-FU/LV arm, a higher proportion of pts had neutrophil-to-lymphocyte ratio (NLR) >5, a marker of poor prognosis, suggesting that higher NLR may potentially be predictive of survival outcome with nal-IRI+5-FU/LV. Conclusions: More pts receiving nal-IRI+5-FU/LV versus 5-FU/LV were alive beyond 1 year. The most prominent prognostic markers of survival ≥1 year included lower CA19-9, KPS ≥90 and absence of liver metastases. These analyses may be limited by small sample sizes.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease. The majority of patients are diagnosed with locally advanced or metastatic disease with a prognosis of short months. Therapeutic options are limited and until recently, there was no standard second-line chemotherapy option. Liposomal constructs have been engineered to encapsulate chemotherapy thereby preventing premature metabolism, improving distribution and minimizing toxicity. Favourable preclinical data on liposomal irinotecan and early phase trials, led to a recently published phase III trial of liposomal irinotecan in combination with fluorouracil and folinic acid in patients with metastatic PDAC, who progressed after gemcitabine-based chemotherapy. As a direct result, the United States Food and Drug Administration (FDA) and European Medicines Agency (EMA) have approved the use of liposomal irinotecan in this setting. However, first-line treatment options for this disease now include the combination regimen, FOLFIRINOX, in patients with good performance status, and the role of second-line combination treatment with liposomal irinotecan in this setting is unclear. Recent advances have changed the therapeutic landscape, as clinicians are now able to choose a sequential approach to treatment tailored to the individual patient characteristics. This article reviews current treatment options for metastatic PDAC and focuses on the efficacy, safety and place in therapy of liposomal irinotecan.

TPS4661 Background: Liposomal irinotecan administered with 5-fluorouracil/leucovorin (5-FU/LV) is approved in the USA for metastatic pancreatic ductal adenocarcinoma (mPDAC) following progression with gemcitabine-based therapy. A phase 1/2 study in previously untreated locally advanced/metastatic PDAC showed promising anti-tumor activity with liposomal irinotecan 50 mg/m2 free base + 5-FU 2400 mg/m2 + LV 400 mg/m2 + oxaliplatin (OX) 60 mg/m2 on days 1 and 15 of a 28-day cycle (Wainberg et al. Ann Oncol 2019;30 Suppl 4: SO-005). Herein, we present the design of the phase 3 NAPOLI-3 study investigating the efficacy and safety of this regimen as first-line therapy in patients with mPDAC. Methods: NAPOLI-3 (NCT04083235) is a phase 3, open-label, randomized, global study in adults with histologically/cytologically confirmed pancreatic adenocarcinoma not previously treated in the metastatic setting. Patients are required to have one or more metastatic tumors measurable with computed tomography/magnetic resonance imaging and an Eastern Cooperative Oncology Group performance status score of 0–1. Site activation began in Dec 2019 and enrollment is ongoing. Random allocation (1:1) of 750 patients is planned to liposomal irinotecan + 5-FU/LV + OX (regimen as per phase 1/2 study) or nab-paclitaxel 125 mg/m2 + gemcitabine 1000 mg/m2 on days 1, 8 and 15 in a 28-day cycle. The primary endpoint is overall survival (OS). Secondary endpoints (progression-free survival [PFS] and overall response rate assessed with Response Evaluation Criteria in Solid Tumors v1.1 criteria) will be compared only if the primary endpoint shows superiority for liposomal irinotecan + 5-FU/ LV + OX over nab-paclitaxel + gemcitabine. Safety assessments include adverse-event monitoring. Patients will continue treatment until disease progression, unacceptable toxicity or study withdrawal, and will then be followed for survival every 2 months until death or study end (when all patients have died, withdrawn consent or are lost to follow-up). Clinical trial information: NCT04083235 .
