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. Clinical trial information: NCT01494506. [Table: see text]

Liposomal Irinotecan

At 9%, and 2% when diagnosed at advanced stage, the 5-year relative survival rate for pancreatic ductal adenocarcinoma (pdac) is the lowest of any cancer. The currently approved treatment options for metastatic pdac in the United States are folfirinox [irinotecan–fluorouracil (5fu)–leucovorin (lv)–oxaliplatin], gemcitabine–nab-paclitaxel, and liposomal irinotecan plus 5fu–lv. Liposomal irinotecan is a novel formulation of irinotecan encapsulated within a lipid bilayer, which favours localmetabolic activation. The napoli-1 trial demonstrated the efficacy of liposomal irinotecan in combination with 5fu and lv for the treatment of advanced pdac after progression on gemcitabine-based chemotherapy. The 1-year survival in those patients was 25%; however, none had had irinotecan-refractory disease before treatment with liposomal irinotecan. Furthermore, the U.S. National Comprehensive Cancer Network guidelines recommend liposomal irinotecan plus 5fu–lv in patients who have received prior fluoropyrimidine-based therapy if no prior irinotecan therapy has been given. Here, we report a male patient with stage iv cancer of pancreas or bile duct (site unconfirmed) who experienced a prolonged (51 weeks) response to liposomal irinotecan plus 5fu–lv despite prior disease progression on irinotecan. Several factors have previously been associated with long-term survival in patients receiving liposomal irinotecan therapy: no prior irinotecan-based chemotherapy, high Karnofsky performance status score, age 65 years or less, serum carbohydrate antigen 19-9 less than 59 U/mL, neutrophil-to-lymphocyte ratio 5 or less, and absence of liver metastasis. The patient in the present report had none of those characteristics indicative of long-term survival, except his age at diagnosis—47 years.

10553 Background: Pazopanib has recently received approval in US, EU & Japan for use in certain STS subtypes. We conducted a retrospective analysis on pooled data from two EORTC clinical trials on pazopanib in STS in order to characterize long term responders and survivors. Methods: Patients selected for analysis were treated with pazopanib in phase II study 62043 (n = 142) and phase III study 62072 (PALETTE) (n = 246). Combined median progression-free survival (PFS) was 4.0 months; median overall survival (OS) was 11.3 months. 34 % of patients had a PFS ≥ 6 months (n = 133) and were defined as long term responders; 33 % of patients survived ≥ 18 months (n = 128), defined as long term survivors. Following patient characteristics were studied: gender, age, performance status, tumor localization, histology, grading, treatment exposure and dose modifications, severity of adverse events and post protocol therapy. Results: Clinical cut-off dates for this analysis resulted in a pooled database with a median follow-up of 2.3 years. Patient characteristics were compared between four subgroups based on short / long term PFS and OS, respectively. 79 patients were both long term responders and long term survivors. The descriptive analysis confirmed the importance of known prognostic factors such as age, performance status and grading, but did not add additional characteristics translating into long term response or survival. We identified 12 patients remaining on pazopanib for more than two years: 9 aged younger than 55 years, 9 females, four with smooth muscle tumors and nine with low or intermediate grade tumors at initial diagnosis. Only two of those patients achieved a partial response; the remaining 10 experienced stable disease as best overall response. Median time on pazopanib in these patients was 2.4 years with the longest duration of 3.7 years. Four patients were still on pazopanib at the end of the studies with a median PFS of 2.3 years and a median OS of 2.8 years. Conclusions: 34 % and 33 % of STS patients given pazopanib in these studies have a long PFS and / or OS respectively. 3.1 % of patients demonstrate a clinical benefit even beyond 2 years.

BackgroundThe NAPOLI-1 trial demonstrated that liposomal irinotecan in combination with fluorouracil (5-FU) and leucovorin (LV) prolonged survival with a manageable safety profile in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) previously treated with gemcitabine-based therapy. Real-world data on clinical outcomes associated with liposomal irinotecan in NAPOLI-1-based regimens is needed to further substantiate this.MethodsThis real-world, retrospective chart review study included patients with mPDAC who received NAPOLI-1-based regimens from six academic centers in the United States. Liposomal irinotecan initiation defined the index date. Overall survival (OS) and progression-free survival (PFS) were assessed with Kaplan-Meier methodology.ResultsThere were 374 patients evaluated; median age was 68 years, and 51% were female. Among 326 patients with baseline ECOG information, approximately 74% had ECOG score <2. Liposomal irinotecan was administered as a doublet with 5-FU in a NAPOLI-1-based regimen in the first line (1L; 16%), 2L (42%), and 3L+ (42%) of the metastatic setting. For patients treated in 1L, 2L, and 3L+, median [95% confidence interval (CI)] OS was 8.0 [5.1, 11.2], 7.3 [5.3, 8.8], and 4.6 [4.0, 5.7] months, and median [95% CI] PFS was 4.2 [2.2, 6.6], 3.0 [2.6, 3.7], and 2.0 [1.7, 2.2] months, respectively.ConclusionsPatients in a real-world setting treated with NAPOLI-1-based liposomal irinotecan doublet regimens at academic centers were older with poorer performance status compared to trial patients yet had similar outcomes and efficacy. Furthermore, liposomal irinotecan was frequently used in the 3L+ setting where no treatment has been approved and provided clinical benefit.

Liposomal Irinotecan

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.

469 Background: The phase III VELOUR study demonstrated that adding the novel antiangiogenic agent aflibercept (known as ziv-aflibercept in the United States) to FOLFIRI in patients with metastatic colorectal cancer previously treated with oxaliplatin significantly improved overall survival, progression-free survival (PFS), and overall response rate versus placebo-FOLFIRI. We performed an additional analysis of PFS “on-treatment,” censoring events that occurred more than 28 days after last treatment dose. Methods: Patients were randomized to receive aflibercept 4 mg/kg or placebo every 2 weeks in combination with FOLFIRI. An independent review committee determined progression based on radiologic review. PFS was estimated using Kaplan-Meier analysis, with censoring of events after the last dose plus 28 days. Treatment groups were compared using a log-rank test stratified by ECOG performance status and prior bevacizumab therapy. Hazard ratio (HR) and confidence interval (CI) were estimated using a Cox proportional hazard model. Results: On-treatment PFS results are shown in the Table. Patients on aflibercept-FOLFIRI showed significantly increased on-treatment PFS compared with patients on placebo-FOLFIRI. More patients were censored in the aflibercept arm due to adverse events, thus decreasing the number of events. Conclusions: On-treatment PFS with aflibercept-FOLFIRI was significantly increased compared with placebo-FOLFIRI, which is consistent with the PFS benefit observed in the primary analysis. Clinical trial information: NCT00561470. [Table: see text]

LBA3 Background: Irinotecan/5-FU/leucovorin (FOLFIRI) or oxaliplatin/5-FU/leucovorin (mFOLFOX6), combined with bevacizumab (BV) or cetuximab (CET), are first-line treatments for metastatic adenocarcinoma of the colon or rectum (MCRC). The optimal antibody combination is unknown. Methods: Patients (pts) with KRAS wild-type (wt)(codons 12 and 13) MCRC and performance status 0-1 received FOLFIRI or mFOLFOX6 (MD/pt choice at enrollment) and randomized to either CET 400 mg/m2 X 1, then 250 mg/m2 qw or BV 5 mg/kg q2w. The original study included unselected MCRC pts receiving FOLFIRI or mFOLFOX6 and randomized to CET, BV, or both. After 1,420 pts accrued the study amended as follows: only pts with KRAS wt tumors (codon 12 and 13) were included and the combination CET + BV arm was deleted. Rx continued until progression, death, unacceptable toxicity, curative surgery; treatment holidays of 4 wks permitted. Subsequent Rx not mandated. Accrual goal was 1,142 pts. One° endpoint was overall survival (OS). Results: Between November 2005 and March 2012, 3,058 unselected pts enrolled, 2,334 KRAS wt pts randomized; final N =1137 (333 pre-amend eligible retrospective KRAS test, 804 post-amend), median f/u = 24 mos; Median age – 59 y; 61% male. Chemo/BV – 559; chemo/CET – 578. FOLFIRI = 26.6%, mFOLFOX6 = 73.4%. OS analysis planned at 849 events; efficacy futility boundary crossed at 10th interim analysis on 1/29/14. OS - chemo/BV v. chemo/CET = 29.04 (25.66 - 31.21) v. 29.93 (27.56 - 31.21) mos; HR = 0.92 (0.78, 1.09) (p value = 0.34). PFS (by investigator): chemo/BV v. chemo/CET: 10.84 (9.86 - 11.4) v. 10.45 (9.66 - 11.33) mos. There were 94 pts free of disease following surgery, median f/u 40 mos (range 8.0 - 86.0). Outcomes similar by gender. On-study toxicity and deaths as expected. Analyses underway: Expanded RAS, FOLFOX v. FOLFIRI, subsequent therapies, long-term survivors, correlates. Conclusions: Chemo/CET and chemo/BV equivalent in OS in pts KRAS wt (codons 12 + 13) MCRC; either is appropriate in first line. Overall OS of 29 + mos and 8% long-term survivors confirms progress in MCRC. The preference for FOLFOX limits chemotherapy comparison. Expanded RAS and other molecular and clinical analyses may identify subsets of pts who get more or less benefit from specific regimens. Clinical trial information: NCT00265850.

Liposomal Irinotecan

There are questions surrounding the real-world effectiveness of chemotherapeutic treatments for pancreatic ductal adenocarcinoma. This literature review compared the clinical characteristics and outcomes of available real-world evidence (RWE) for liposomal irinotecan in combination with 5-fluorouracil (5-FU) and leucovorin (LV), a treatment regimen indicated for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) who previously progressed on gemcitabine-based therapy. A targeted literature search was conducted in the PubMed Central® and Embase® databases to identify available RWE regarding patients with mPDAC receiving liposomal irinotecan published within the last 5 years (January 2014–September 2019). Data were extracted for prior lines of therapy, performance status, overall survival (OS), progression-free survival (PFS), duration of exposure, and adverse events. Six studies met inclusion criteria. A comparison of baseline patient characteristics and results with the included evidence reveals a clinically fragile, real-world patient population in terms of age (range: 61–68), prior lines of therapy with 34–61% of patients receiving ⩾2 lines of lines of prior therapy and performance status [49.8–100% of patients with Eastern Cooperative Oncology Group (ECOG) 0–1]. Studies observed wide OS (range: 5.3–9.4 months) and similar PFS (range: 2.3–4.1 months), with two studies measuring duration of exposure (7.3 weeks, 3.1 months). Patients analyzed by RWE studies tended to be older with significant disease progression, poor performance status, and more heavily pretreated compared with the phase III registrational trial (NAPOLI-1). Despite this, patients treated with liposomal irinotecan + 5-FU/LV therapy had similar outcomes as those in NAPOLI-1.

Prognostic And Predictive Markers

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.
