Quality-adjusted survival with combination nal-IRI+5-FU/LV vs 5-FU/LV alone in metastatic pancreatic cancer patients previously treated with gemcitabine-based therapy: a Q-TWiST analysis.

ABSTRACT: BACKGROUND:In the NAPOLI-1 Phase 3 trial, nal-IRI+5-fluorouracil and leucovorin (5-FU/LV) significantly improved median overall survival (6.1 vs 4.2 months, P=0.012) and progression-free survival (3.1 vs 1.5 months, P=0.0001) vs 5-FU/LV alone in metastatic pancreatic adenocarcinoma patients previously treated with gemcitabine-based therapy. This analysis evaluated between treatment differences in quality-adjusted time without symptoms of disease progression or toxicity (Q-TWiST). METHODS:Overall survival was partitioned into time with grade ?3 toxicity (TOX), disease progression (REL), and time without disease progression symptoms or grade ?3 toxicity (TWiST). Mean Q-TWiST was calculated by weighting time spent by a utility of 1.0 for TWiST and 0.5 for TOX and REL. In threshold analyses, utility for TOX and REL were varied from 0.0 to 1.0. RESULTS:Patients in nal-IRI+5-FU/LV (n=117) vs 5-FU/LV (n=119) had significantly more mean time in TWiST (3.4 vs 2.4 months) and TOX (1.0 vs 0.3 months) but similar REL (2.5 vs 2.7 months). In the base case, nal-IRI+5-FU/LV patients had 1.3 months (95% CI, 0.4-2.1; 5.1 vs 3.9) greater Q-TWiST (threshold analyses range: 0.9-1.6 months). CONCLUSIONS:Within NAPOLI-1, nal-IRI+5-FU/LV resulted in statistically significant and clinically meaningful gains in quality-adjusted survival vs 5-FU/LV alone.

Project description:BACKGROUND:Biliary tract cancer (BTC) has a high mortality. Primary diagnosis is frequently delayed due to mostly unspecific symptoms, resulting in a high number of advanced cases at the time of diagnosis. Advanced BTCs are in principle chemotherapy sensitive as determined by improved disease control, survival and quality of life (QoL). However, median OS does not exceed 11.7?months with the current standard of care gemcitabine plus cisplatin. Thereby, novel drug formulations like nanoliposomal-irinotecan (nal-IRI) in combination with 5- fluorouracil (5-FU)/leucovorin may have the potential to improve therapeutic outcomes in this disease. METHODS:NIFE is an interventional, prospective, randomized, controlled, open label, two-sided phase II study. Within the study, 2?×?46 patients with locally advanced, non-resectable or metastatic BTC are to be enrolled by two stage design of Simon. Data analysis will be done unconnected for both arms. Patients are allocated in two arms: Arm A (experimental intervention) nal-IRI mg/m2, 46?h infusion)/5-FU (2400?mg/m2, 46?h infusion)/leucovorin (400?mg/m2, 0.5?h infusion) d1 on 14?day-cycles; Arm B (standard of care) cisplatin (25?mg/m2, 1?h infusion)/gemcitabine (1000?mg/m2, 0.5?h infusion) d1 and d8 on 21?day-cycles. The randomization (1:1) is stratified for tumor site (intrahepatic vs. extrahepatic biliary tract), disease stage (advanced vs. metastatic), age (?70 vs. >?70?years), sex (male vs. female) and WHO performance score (ECOG 0 vs. ECOG 1). Primary endpoint of the study is the progression free survival (PFS) rate at 4?months after randomization by an intention-to-treat analysis in each of the groups. Secondary endpoints are the overall PFS rate, the 3-year overall survival rate, the disease control rate after 2?months, safety and patient related outcome with quality of life. The initial assessment of tumor resectability for locally advanced BTCs is planned to be reviewed retrospectively by a central surgical board. Exploratory objectives aim at establishing novel biomarkers and molecular signatures to predict response. The study was initiated January 2018 in Germany. DISCUSSION:The NIFE trial evaluates the potential of a nanoliposomal-irinotecan/5-FU/leucovorin combination in the first line therapy of advanced BTCs and additionally offers a unique chance for translational research.

Project description:BackgroundRigosertib (ON 01910.Na), a first-in-class Ras mimetic and small-molecule inhibitor of multiple signaling pathways including polo-like kinase 1 (PLK1) and phosphoinositide 3-kinase (PI3K), has shown efficacy in preclinical pancreatic cancer models. In this study, rigosertib was assessed in combination with gemcitabine in patients with treatment-naïve metastatic pancreatic adenocarcinoma.Materials and methodsPatients with metastatic pancreatic adenocarcinoma were randomized in a 2:1 fashion to gemcitabine 1000 mg/m(2) weekly for 3 weeks of a 4-week cycle plus rigosertib 1800 mg/m(2) via 2-h continuous IV infusions given twice weekly for 3 weeks of a 4-week cycle (RIG + GEM) versus gemcitabine 1000 mg/m(2) weekly for 3 weeks in a 4-week cycle (GEM).ResultsA total of 160 patients were enrolled globally and randomly assigned to RIG + GEM (106 patients) or GEM (54). The most common grade 3 or higher adverse events were neutropenia (8% in the RIG + GEM group versus 6% in the GEM group), hyponatremia (17% versus 4%), and anemia (8% versus 4%). The median overall survival was 6.1 months for RIG + GEM versus 6.4 months for GEM [hazard ratio (HR), 1.24; 95% confidence interval (CI) 0.85-1.81]. The median progression-free survival was 3.4 months for both groups (HR = 0.96; 95% CI 0.68-1.36). The partial response rate was 19% versus 13% for RIG + GEM versus GEM, respectively. Of 64 tumor samples sent for molecular analysis, 47 were adequate for multiplex genetic testing and 41 were positive for mutations. The majority of cases had KRAS gene mutations (40 cases). Other mutations detected included TP53 (13 cases) and PIK3CA (1 case). No correlation between mutational status and efficacy was detected.ConclusionsThe combination of RIG + GEM failed to demonstrate an improvement in survival or response compared with GEM in patients with metastatic pancreatic adenocarcinoma. Rigosertib showed a similar safety profile to that seen in previous trials using the IV formulation.
