BACKGROUND: Pancreatic ductal adenocarcinoma remains one of the most lethal malignancies, with few treatment options. NAPOLI 3 aimed to compare the efficacy and safety of NALIRIFOX versus nab-paclitaxel and gemcitabine as first-line therapy for metastatic pancreatic ductal adenocarcinoma (mPDAC). METHODS: NAPOLI 3 was a randomised, open-label, phase 3 study conducted at 187 community and academic sites in 18 countries worldwide across Europe, North America, South America, Asia, and Australia. Patients with mPDAC and Eastern Cooperative Oncology Group performance status score 0 or 1 were randomly assigned (1:1) to receive NALIRIFOX (liposomal irinotecan 50 mg/m2, oxaliplatin 60 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2, administered sequentially as a continuous intravenous infusion over 46 h) on days 1 and 15 of a 28-day cycle or nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2, administered intravenously, on days 1, 8, and 15 of a 28-day cycle. Balanced block randomisation was stratified by geographical region, performance status, and liver metastases, managed through an interactive web response system. The primary endpoint was overall survival in the intention-to-treat population, evaluated when at least 543 events were observed across the two treatment groups. Safety was evaluated in all patients who received at least one dose of study treatment. This completed trial is registered with ClinicalTrials.gov, NCT04083235. FINDINGS: Between Feb 19, 2020 and Aug 17, 2021, 770 patients were randomly assigned (NALIRIFOX, 383; nab-paclitaxel-gemcitabine, 387; median follow-up 16·1 months [IQR 13·4-19·1]). Median overall survival was 11·1 months (95% CI 10·0-12·1) with NALIRIFOX versus 9·2 months (8·3-10·6) with nab-paclitaxel-gemcitabine (hazard ratio 0·83; 95% CI 0·70-0·99; p=0·036). Grade 3 or higher treatment-emergent adverse events occurred in 322 (87%) of 370 patients receiving NALIRIFOX and 326 (86%) of 379 patients receiving nab-paclitaxel-gemcitabine; treatment-related deaths occurred in six (2%) patients in the NALIRIFOX group and eight (2%) patients in the nab-paclitaxel-gemcitabine group. INTERPRETATION: Our findings support use of the NALIRIFOX regimen as a possible reference regimen for first-line treatment of mPDAC. FUNDING: Ipsen.

OBJECTIVES: Aflibercept (ziv-aflibercept) significantly improves progression-free (PFS) and overall survival (OS) when added to 5-fluorouracil, leucovorin and irinotecan (FOLFIRI), compared with FOLFIRI alone, in patients with metastatic colorectal cancer previously treated with oxaliplatin-based therapy. This subset analysis of the VELOUR study investigates aflibercept plus FOLFIRI versus placebo plus FOLFIRI according to age. METHODS: Efficacy and safety were analyzed by treatment arm and age (≥ or <65years). RESULTS: Overall, 443 patients were ≥65years old (205 in aflibercept arm; 238 in placebo arm) and 783 were <65years old (407 in aflibercept arm; 376 in placebo arm). Median OS was 12.6 versus 11.3months (hazard ratio [HR]: 0.85; 95.34% CI 0.68-1.07) in patients ≥65years old and 14.5 versus 12.5months (HR: 0.80; 95.34% CI 0.67-0.95) in those patients <65years old, for patients receiving FOLFIRI plus aflibercept or placebo, respectively. There was no interaction between treatment and age. Treatment-emergent adverse events (AEs) were comparable for patients <65years and ≥65years old. The incidence of grade 3/4 AEs was higher for patients ≥65years old than for those <65years old in both the aflibercept (89.3% versus 80.5%) and placebo (67.4% versus 59.4%) arms. Interaction tests for grade 3/4 antiangiogenic agent-related AEs suggested no heterogeneity between the older and younger patient populations (p>0.1). CONCLUSION: A limited but consistent benefit on both OS and PFS was associated with the addition of aflibercept to FOLFIRI compared with placebo in patients <65 and ≥65years old, with a marked but manageable increase in the toxicity profile in older patients.

The aim of this post hoc analysis of the VELOUR study (ClinicalTrials.gov NCT00561470) was to investigate the treatment effect of adding aflibercept to second-line infusional 5-fluorouracil (5-FU), leucovorin and irinotecan (FOLFIRI) in patients with metastatic colorectal cancer (mCRC) who had failed any prior oxaliplatin-containing regimen. Adjuvant rapid relapsers (ARR), who were enrolled directly following relapse during or within 6 months of completion of oxaliplatin-containing adjuvant chemotherapy (N = 124, including 17 patients who also received bevacizumab as part of their adjuvant therapy), were excluded from the original VELOUR intention-to-treat (ITT) population (N = 1226). After exclusion of the ARR, overall survival (OS) in the ITT minus ARR (ITT-ARR) population (N = 1102) was longer in the aflibercept plus FOLFIRI arm than in the placebo plus FOLFIRI arm [hazard ratio (HR) 0.78, 95 % confidence interval (CI) 0.68-0.90; median survival difference 1.87 months]. In the subgroup of patients assigned to the prior bevacizumab stratum at randomization, OS was numerically longer in the aflibercept plus FOLFIRI arm than in the placebo plus FOLFIRI arm (HR 0.81; 95 % CI 0.63-1.04; median survival difference 2.14 months). Comparison of the post hoc analysis results with the primary analysis from VELOUR suggests that the inclusion of the directly enrolled ARR may have understated the aflibercept treatment benefit for both bevacizumab-pretreated and bevacizumab-naïve patients in the strictly second-line setting although no definitive conclusion may be inferred. The benefit associated with the addition of aflibercept to second-line FOLFIRI in patients with mCRC was observed whatever the timing of first-line disease progression. There were no unexpected safety concerns.

BACKGROUND: Patients with metastatic colorectal cancer (mCRC) previously-treated with oxaliplatin benefit significantly from the addition of aflibercept to FOLFIRI in relation to overall survival, progression-free survival and response rate. PATIENTS AND METHODS: The results for efficacy and safety over the time course of the VEGF Trap (aflibercept) with irinotecan in colorectal cancer after failure of oxaliplatin regimen trial were analysed based on data from 1226 patients randomised to receive FOLFIRI plus either aflibercept (n=612) or placebo (n=614). Hazard ratios (HR) by 6-month time period were estimated using a piecewise Cox proportional hazard model. Severity of adverse events (AEs) was graded using National Cancer Institute Common Terminology Criteria, version 3.0. RESULTS: The estimated probabilities of survival were 38.5% versus 30.9% at 18 months, 28.0% versus 18.7% at 24 months and 22.3% versus 12.0% at 30 months, for the aflibercept- and placebo-treated arms, respectively. The proportional improvement in the HR over time was consistent with the survival probability results; survival at 24 months was improved by 50% and almost doubled at 30 months. The majority of worst-grade AEs occurred within the first four cycles of treatment and in a small percent of treatment cycles and were mostly reversible. Common chemotherapy- and anti-vascular epithelial growth factor (VEGF)-associated AEs occurred rarely and in a small proportion of cycles with the majority being of single occurrence. CONCLUSIONS: The addition of aflibercept to FOLFIRI showed a continued and persistent improvement in overall survival over time in patients with mCRC. Although grade 3-4 AEs were more frequent in the aflibercept arm, they occurred in early treatment cycles and decreased sharply following initial presentation.

In the last years, interesting advances have been reported in the treatment of infrequent digestive tumors. The increasing development of new targeted therapies in human cancer has also impacted in these rare gastrointestinal malignancies providing a wide range of possibilities in the design of future clinical trials. RECENT FINDINGS: The inhibition of angiogenesis and the blockage of the epidermal growth factor receptor pathway have provided the most interesting activity in recently reported studies for esophageal and biliary tract carcinomas. Additionally, several targeted therapies have been developed to target the main kinase proteins of the most important pathways of these malignancies. The results of the biggest phase III trial in locally advanced anal carcinoma have been recently published. Finally, the inhibition of epidermal growth factor receptor has also showed promising activity in anal carcinomas. SUMMARY: Recent advances in the knowledge of molecular mechanism of carcinogenesis have led to meaningful changes in the management of gastrointestinal cancers. Although the major advances in targeted therapy have been introduced in the treatment of colorectal cancer, new interesting approaches have been reported in less frequent gastrointestinal tumors such as esophageal, biliary tract, and anal canal carcinoma opening a new hope in the treatment of these rare tumors in the molecular targeted therapy era.
