Gemcitabine and nab-paclitaxel (GEM-NAB) and the combination of 5-fluorouracil, oxaliplatin, and irinotecan (FOLFIRINOX) are valid first-line options for advanced or metastatic pancreatic cancer (mPC). However, no randomized trials comparing the two schemes have been performed. This meta-analysis aims to compare GEM-NAB and FOLFIRINOX in terms of safety and effectiveness, taking into account data from real-life studies on mPC. We systematically searched PubMed, EMBASE and Cochrane library up to November 2018 to identify retrospective or cohort studies on mPC comparing GEM-NAB and FOLFIRINOX. We included 16 retrospective studies, including 3813 patients (2123 treated with GEM-NAB and 1690 treated with FOLFIRINOX). Despite a median weighted overall survival (OS) difference in favor of FOLFIRINOX (mean difference: 1.15, 95% confidence interval CI 0.08–2.22, p = 0.03), in whole population OS was similar (hazard ratio (HR = 0.99, 95% CI 0.84–1.16; p = 0.9). PFS was also not different between the two arms (HR = 0.88, 95% CI 0.71–1.1; p = 0.26). The overall response rate was similar (25 vs. 24% with GEM-NAB and FOLFIRINOX). Among grade 3–4 toxicities, neutropenia, febrile neutropenia, and nausea were lower with GEM-NAB, while neurotoxicity and anemia were lower with FOLFIRINOX. In conclusion, despite a numerically longer median OS with FOLFIRINOX as compared to GEM-NAB, the overall risk of death and progression were similar. Their toxicity was different with less nausea, neutropenia, and febrile neutropenia with GEM-NAB, as compared to less neurotoxicity and anemia with FOLFIRINOX. Therefore, analysis of non-randomized “real world” studies to date has not provided evidence of a major benefit of one regimen over the other.

Abstract Purpose: To compare the efficacy and toxicity of three different chemotherapy regimens used as first-line treatments in the real-life management of metastatic pancreatic cancer (mPC). Methods: A total of 218 patients diagnosed with mPC at the time of initial admission were included in this multicenter study. Gemcitabine (Gem, n=71), Gemcitabine-cisplatin (Gem-Cis, n=91) and FOLFIRINOX (FFX, n=56) treatments were compared in terms of efficacy and treatment-related toxicity. Results: Overall response rate was significantly higher in the FFX group (50.0%) than in the Gem (28.2%) and Gem-Cis (27.5%) groups (p=0.010).Median progression-free survival (8.4 vs. 4.6 and 5.5 months, respectively, p<0.001) and overall survival (16.4 vs. 8.1 and 8.7 months, respectively, p=0.002) were significantly longer in theFFX group than in the Gem and Gem-Cis groups. Toxicity of any grade was noted in 46(64.8%), 56(61.5%) and 49(87.5%) patients in the Gem, Gem-Cis and FFX groups, respectively (p=0.003).Of the grade 3-4 toxicities, weakness/fatigue and mucositis were reported only in the FFX group (5.4% and 3.6%, respectively). Grade 3-4 diarrhea (10.7%, 0.0%, 2.2%, respectively) and neutropenia (25%, 4.2% and 5.5%, respectively) were more common in the FFX group than in the Gem and Gem-Cis groups. Conclusion: In conclusion, our findings indicate that FFX regimen provides a significant advantage over the other treatment regimens in terms of response rates and survival. Treatment toxicity was more frequent but manageable with the FFX regimen.FFX seems to be a preferable regimen in the first-line treatment of the younger and fit patients diagnosed with mPC.

e16506 Background: ICI have proven to benefit patients diagnosed with aUC who are platinum-ineligible. The role of platinum-eligible patients, in the first-line setting is being further elucidated after single positive randomized clinical trial (RCT) with ICI. Hence, we performed a meta-analysis to interpret the association of Overall Survival (OS) and PD-1 or PD-L1 inhibitors as first-line therapies in platinum-eligible patients with aUC. Methods: Randomized controlled trials were retrieved from PubMed, Web of Science, and Cochrane Library according to established inclusion criteria. Each article was assessed by the Newcastle-Ottawa Scale. The Hazard Risk (HR) and 95% confidence intervals (CI) were calculated. Random effect or fixed-effect model was used to calculate the pooled HR, based on heterogeneity significance. Sensitivity analysis and publication bias detection were performed. All statistical analysis were performed using RevMan software (v5.4; Cochrane library) and R Core Team (2016, Vienna, Austria), and all p-values were two-tailed, and the significance level was 0.05. Results: Sixty-seven articles were obtained from the database search, and based on inclusion/exclusion criteria, five RCTs were selected involving 4063 patients. All studies were considered moderate to high quality. A statistically significant association was found between initiation of immunotherapy as first-line treatment to platinum-eligible patients and increased OS (HR 0.87; 95% CI: 0.81,0.94, p = 0.004, I2= 38%). The subgroup analysis included positive PD1 (HR 0.81; 95% CI: 0.70,0.94, p = 0.004, I2= 34%) vs. negative expression (HR 0.96; 95% CI: 0.83,1.11, p = 0.58, I2= 0%); cisplatin (HR 0.81; 95% CI: 0.69,0.96, p = 0.02, I2= 47%) vs. carboplatin administration (HR 0.87; 95% CI: 0.76,1.01, p = 0.06, I2= 21%); male (HR 0.87; 95% CI: 0.77,0.97, p = 0.01, I2= 44%) vs. female (HR 0.85; 95% CI: 0.70,1.04, p = 0.11, I2= 0%); ECOG score 0 (HR 0.77; 95% CI: 0.67,0.89, p = 0.0005, I2= 0%) vs. ≥ 1 (HR 0.90; 95% CI: 0.78,1.02, p = 0.11, I2= 6%); Caucasian (HR 0.81; 95% CI: 0.73, 0.91, p = 0.0003, I2= 39%) vs. other race (HR 0.92; 95% CI: 0.75, 1.13, p = 0.44, I2= 0%). Similar association regardless of visceral lesion or age. Funnel plot, Egger's test (p = 0.6944), and Begg's test (0.7726) found no publication bias of analysis. Conclusions: This meta-analysis showed improved OS in platinum-eligible patients receiving first-line ICI in aUC. Furthermore, a subgroup analysis yielded an increased OS and cisplatin, positive PD1 status, ECOG 0, male gender, and Caucasian race. In this rapidly evolving clinical practice changes, our meta-analysis provides support to currently recommended avelumab maintenance after platinum induction therapy in the first-line setting and further provide guidance on patient selection for aUC.

Significant Difference

Introduction: Pancreatic cancer is an aggressive tumor that had an estimated 57,600 new cases and 47,050 deaths in 2020 in the US alone. Recent studies have targeted tumor microenvironment (TME) for better delivery of systemic chemotherapy like PEGPH20, which degrades hyaluronic acid in the extracellular matrix (ECM). A meta-analysis of these Randomized controlled trials (RCTs) to test the efficacy of PEGPH20 was performed. Methods: A systematic search was performed using PubMed, Embase, and Cochrane library without language limitations from inception to July 30, 2020. A total of 59 articles was identified, and 3 RCTs were included in the final analysis. The primary outcome was progression-free survival (PFS), and secondary outcomes were overall survival (OS), deaths from adverse events, thromboembolic events, serious adverse events (SAE), and febrile neutropenia. Results: There was no statistically significant improvement in PFS (HR= 0.94; 95%CI (0.79, 1.11)) in the PEGPH20 group when compared to the standard treatment/placebo group. There was no significant difference among OS (HR= 0.99, 95%CI (0.83, 1.17), deaths from adverse events (RR=0.97; 95%CI (0.54, 1.73)), thromboembolic events (RR= 1.49; 95%CI (0.92, 2.44)), and febrile neutropenia (RR= 0.88; 95%CI (0.45, 1.72), however, there was statistically significant increase in SAE (RR = 1.59; 95%CI (1.01, 2.52) in the PEGPH20 group compared to the placebo group. Conclusion: This meta-analysis showed that PEGPH20 did not improve the PFS or OS. Moreover, there is an increased incidence of serious adverse events with the use of PEGPH20 compared to standard therapies.

The Impact

534 Background: Biologic therapies used in treatment of mCRC are expensive and there is debate about their value. We examined the impact of biologic therapy on overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and grade 3/4 toxicity for patients beyond first-line treatment. Methods: MEDLINE, EMBASE, and Cochrane libraries were searched for randomized studies in relapsed mCRC comparing treatment containing targeted therapy to the same treatment without targeted therapy. Biologic agents were classed as: EGFR-inhibitors (EGFR-I), VEGF antibody/trap and VEGFR tyrosine kinase inhibitors (TKI). Only KRAS wild-type patients were included for EGFR-I analysis. Results were aggregated according to standard meta-analytic techniques. Results: 10 studies evaluating 5,847 patients were identified. Considering subgroups and lines, OS and PFS benefit was demonstrated in all groups across all lines except for OS in 2nd line EGFR-I use (which may be due to subsequent crossover). A benefit to ORR was seen with EGFR-I 2nd line (Pooled ORR benefit +24%, Odds Ratio (OR) 4.44, 95% CI 3.20-6.18), EGFR-I 3rd line and beyond (Pooled ORR benefit +16%), VEGF antibody/trap (Pooled ORR benefit +7.2%, OR 2.00, 95% CI 1.57-2.54) and VEGFR TKI (Pooled ORR benefit +1.9%, OR 2.05, 95% CI 1.27-3.30). The risk of grade 3/4 toxicity was greater with the addition of all targeted agents. Conclusions: The use of VEGF and EGFR targeted biologic agents beyond first-line setting in mCRC results in a benefit to OS, PFS and ORR for all agents except for OS benefit with second-line EGFR-I. This benefit comes at the cost of increased toxicity. [Table: see text]

351 Background: FOLFIRINOX is an approved regimen for metastatic pancreatic cancer (mPC). We performed a modification in FOLFIRINOX schedule, using nab-paclitaxel (nab-p) to obtain two regimens that could be as effective and less toxic than the original triplet. NabucCO study was a randomized phase II trial to assess activity and toxicity of nab-p instead of either oxaliplatin (Nab-FOLFIRI) or irinotecan (Nab-FOLFOX) in first line setting. Previous dose–finding NabucCO study defined that maximum tolerated dose of nab-p with FOLFIRI is 120 mg/m2, and with FOLFOX is 160 mg/m2. Methods: The study was a 1:1 parallel arm, open label, not comparative one to assess overall response rate (ORR) of Nab-FOLFIRI and Nab-FOLFOX as primary end-point. Patients (pts) with PS 0-1, untreated for mPC were randomized to receive leucovorin 400 mg/m2, 5FU bolus 400 mg/m2, 5FU 48h ci 2400 mg/m2, irinotecan 180 mg/m2 plus nab-p 120 mg/m2 (arm A) or leucovorin 400 mg/m2, 5FU bolus 400 mg/m2, 5FU 48h ci 2400 mg/m2 and oxaliplatin 85 mg/m2 iv plus nab-p 160 mg/m2 (arm B) every 2 weeks for up to 12 cycles. Secondary end points were clinical benefit rate (CBR), progression free survival (PFS), overall survival (OS), and safety. Results: From November 2015 to January 2017, 84 pts were treated (42 for each arm). Median age was 60 years (29-65) in arm A and 64 years (47-64) in arm B. The ORR was 31 % for both schedules, with a CBR of 69% and 71%, respectively. At a median follow-up of 11.4 months for arm A and 14.5 months for arm B (censored on august, 31th 2017), 1-year survival is 41% and 50%, respectively. For Nab-FOLFIRI PFS and mOS were 6 months (90% CI: 4.9-8.0) and 13.2 months (90% CI: 8.3-14.8), while in Nab-FOLFOX were 5.6 months (90% CI:4.9-7.2) and 10.8 months (90% CI: 8.4-12.8). Grade ≥3 toxicities in arm A were neutropenia (19%) and febrile neutropenia (12%). In arm B, main grade ≥3 toxicities were neutropenia (29%), fatigue (14%), peripheral neuropathy (7%). No toxic death were registered. Conclusions: Nab-FOLFIRI and Nab–FOLFOX demonstrated a similar activity to FOLFIRINOX, with better safety profile in terms of neutropenia, fatigue and neuropathy. These results could justify a future phase III evaluation. Clinical trial information: NCT02109341.

(1) Background: The optimal timing of adjuvant chemotherapy (CT) in gastrointestinal malignancies is still a matter of debate. For colorectal cancer, it is recommended to start post-operative treatment within eight weeks. The objective of this study was to assess the clinical effects of starting adjuvant CT within or after 6–8 weeks post-surgery in colorectal, gastric, and pancreatic cancer. (2) Methods: MEDLINE, EMBASE, and the Cochrane Library were searched in December 2018. Publications comparing the outcomes of patients treated with adjuvant CT administered before (early) or after (delayed) 6–8 weeks post-surgery for colorectal, gastric, and pancreatic cancer were identified. The primary endpoint was overall survival (OS). (3) Results: Out of 8752 publications identified, 34 comparative studies assessing a total of 141,853 patients were included. Meta-analysis indicated a statistically significant increased risk of death with delayed CT (>6–8 weeks post-surgery) in colorectal cancer (hazard ratio (HR) = 1.27, 95% confidence interval (CI) 1.21–1.33; p <0.001). Similarly, for gastric cancer, delaying adjuvant CT was associated with inferior overall survival (HR = 1.2, 95% CI 1.04–1.38; p = 0.01). Conversely, the benefit of earlier CT was not evident in pancreatic cancer (HR = 1, 95% CI 1–1.01; p = 0.37). Conclusions: Starting adjuvant CT within 6–8 weeks post-surgery is associated with a significant survival benefit for colorectal and gastric cancer, but not for pancreatic cancer.

Abstract Neutropenia is a common side effect associated with nab-paclitaxel gemcitabine (Nab-Gem) therapy. We retrospectively investigated the association between neutropenia induced by first-line Nab-Gem and survival in metastatic pancreatic carcinoma patients. Metastatic pancreatic patients treated with first-line Nab-Gem were included in this retrospective analysis. Neutropenia was categorized using the National Cancer Institute Common Toxicity Criteria scale. Outcome measures were overall survival (OS), progression-free survival (PFS) and response rate. 115 patients were analyzed. Median PFS was 7 months (95% CI 5–8) for patients with grade ≥ 3 neutropenia and 6 months (95% CI 5–6) for patients with grade < 3 neutropenia [p = 0.08; hazard ratio (HR 0.68)]. Median OS was 13 months (95% CI 10–18) for patients with grade ≥ 3 neutropenia and 10 months (95% CI 8–13) for patients with grade < 3 neutropenia (p = 0.04; HR 0.44). In multivariate analysis, the occurrence of grade ≥ 3 neutropenia showed a statistically significant association with OS (HR 0.62; 95% CI 0.09–0.86; p = 0.05). Nab-Gem-induced neutropenia is associated with longer survival in metastatic pancreatic cancer patients.

452 Background: IDO is a tryptophan-catabolizing enzyme that plays a key role in the normal regulation of peripheral immune tolerance. Tumors also employ this mechanism to induce a state of immunosuppression. In cancer, IDO mediates an acquired immune tolerance towards tumors, allowing evasion of immune mediated destruction. Indoximod is a broad IDO pathway inhibitor, as it has been shown to potentially interfere with multiple targets within the IDO pathway. Pre-clinical models have demonstrated synergy between indoximod and chemotherapy. The combination of gemcitabine (Gem) and nab-paclitaxel (Nab) is a current SOC for first line treatment of metastatic pancreas cancer. This trial is designed to determine the potential for benefit of combination therapy with indoximod and Gem / Nab for to patients with metastatic pancreatic cancer. Methods: Indoximod was escalated (600mg/1000mg/1200mg PO twice daily continuous dosing) in combination with Gem / Nab (1000mg/m2 / 125mg/m2 q week x 3 per 4 week cycle) in a 3+3 design. Patients were first line metastatic pancreatic cancer or minimum 6 months from adjuvant chemo and / or radiation following previous resection. Treatment continues until progression or toxicity. Primary endpoints for Phase 1 include safety, toxicity, and determination of a Phase 2 dose. The prospective collection of tumor samples for exploration of biomarkers is built into the trial. Results: 15 patients were required to successfully dose escalate the Phase 1 study to 1200 mg twice daily. Two patients were replaced in the lowest dose cohort after rapid deterioration due to underlying disease during the regimen limiting toxicity (RLT) window. One RLT was observed during the study (ascites Grade 3) at the highest dose cohort. The most common AE’s (all Grade 1 or 2) occurring in ≥ 4 subjects, regardless of attribution, were nausea, fatigue, peripheral edema, peripheral neuropathy, alopecia. Conclusions: Indoximod and Gem / Nab were well tolerated in a clinical trial setting. The Phase 2 dose was set at 1200 mg twice daily and Phase 2 enrollment (target 80 patients) is ongoing. Updated results will be presented. Clinical trial information: NCT02077881.

FOLFIRINOX (FFX) and gemcitabine + nab-paclitaxel (GN) are the most common chemotherapy regimens in first-line treatment of metastatic pancreatic cancer (PC). They have not been compared each other in a prospective trial, but only in retrospective studies, which can thus be affected by several biases. In order to overcome these biases, we took advantage of matching-adjusted indirect comparison (MAIC), that allows an indirect comparison by reducing cross-trial differences, and compared data from 268 patients treated with GN in a real-world setting with data from the 171 patients included in the FFX arm of the PRODIGE trial. Survival outcomes did not differ between the two populations. Overall survival was 11.1 months for both treatments (hazard ratio (HR) of FFX 1.10, 95% confidence interval (CI) 0.81–1.49; p = 0.527). Progression-free survival was 6.0 months with GN and 6.4 months with FFX (HR of FFX 1.11, 95% CI 0.82–1.50; p = 0.520). On the other hand, we observed a difference in the toxicity profiles: grade 3/4 anemia was more frequent with GN, whereas a higher occurrence of grade 3/4 vomiting and diarrhea was reported with FFX. FFX and GN show an equivalent efficacy but different safety profiles in the first-line therapy of metastatic pancreatic cancer. Searching for reliable predictive biomarkers is advised in order to improve therapeutic strategy in metastatic PC.
