Background: Folfirinox (FFX) and gemcitabine/nab-paclitaxel (GN) are both standard first-line treatments in patients with metastatic pancreatic cancer (mPC). However, data comparing these two chemotherapeutic regimens and their sequential use remain scarce. Methods: Data from two independent cohorts enrolling patients treated with FFX ( n = 107) or GN ( n = 109) were retrospectively pooled. Primary endpoint was overall survival (OS). Progression-free survival (PFS) was the secondary endpoint. A propensity score based on age, gender, performance status (PS), and presence of liver metastases was used to make groups comparable. Results: In the whole study population, OS was significantly higher in FFX (14 months; 95% CI: 10–21) than in GN groups (9 months; 95% CI: 8–12) before ( p = 0.008) and after ( p = 0.021) adjusting for age, number of metastatic sites, liver metastases, peritoneal carcinomatosis and CA19.9 level at baseline. PFS tends to be higher in FFX (6 months) than GN groups (5 months; p = 0.053). After matching ( n = 49/group), patients were comparable for all baseline characteristics including PS. In the matched population, there was a trend toward greater OS in patients treated with FFX (HR = 0.67; p = 0.097). However, survival in each group was not solely a result of the first-line regimen. The proportion of patients who were fit for GN after FFX failure (FFX–GN sequence) was higher (46.9%) than the reverse sequence (20.4%; p = 0.01), which suggests a higher feasibility for the FFX–GN sequence. Corresponding median OS were 19 months versus 9.5 months, respectively ( p = 0.094). Conclusion: This study shows greater OS with FFX than with GN in patients with mPC. GN after FFX failure appears more feasible than the reverse sequence.

466 Background: Gemcitabine (GEM) plus nab-paclitaxel (GnP) and FOLFIRINOX (FFX) are standard first-line chemotherapy regimens for metastatic pancreatic cancer (MPC) patients. GEM and S-1 are also used for these patients in Japan. However, the phase 3 trials included a small proportion of recurrent pancreatic cancer (RPC) patients, and patients who had received adjuvant chemotherapy were excluded. In clinical practice, RPC is treated in the same way as MPC. The aim of this study is to compare the efficacy of chemotherapy between RPC and MPC. Methods: We retrospectively analyzed the patients with RPC or MPC who received GnP, FFX, GEM, or S-1 as first-line chemotherapy between January 2014 and March 2016 in our institution. RPC was defined as pancreatic cancer with recurrence after R0 or R1 resection. Overall survival (OS), progression-free survival (PFS), response rate (RR), and disease control rate (DCR) were evaluated. Multivariate analyses of OS were performed with the use of a Cox proportional-hazard model. Results: A total of 181 patients, 40 RPC and 141 MPC, were selected in this study. RPC and MPC groups were similar with respect to age, sex, and performance status (PS). However, the RPC group had lower percentage of liver metastases (P < 0.001). The regimens were GnP/FFX/GEM/S-1: 10/3/20/7 in the RPC group and 37/34/67/3 in the MPC group, respectively. In the RPC group, 31 of 40 patients had received adjuvant chemotherapy; S-1/GEM: 24/7. The median OS was 16.6 months in the RPC group as compared with 9.7 months in the MPC group (hazard ratio [HR] 0.64, 95% confidence interval [CI] 0.37–1.10, P = 0.11). The median PFS was 4.8 months in the RPC group and 4.4 months in the MPC group (HR 0.86, 95% CI 0.57–1.30, P = 0.47). The RR was 10% versus 14% (P = 0.79), the DCR was 50% versus 52% (P = 0.86), in the two groups, respectively. Multivariate analysis showed PS (HR 2.19, 95% CI 1.38–3.49) and liver metastases (HR 2.34, 95% CI 1.47–2.34) were independent predictors of OS. On the other hand, RPC or MPC was not found to be an independent prognostic factor (HR 1.19, 95% CI 0.67–2.13). Conclusions: It is suggested that chemotherapy in RPC may have similar efficacy compared to MPC. The relatively longer OS in the RPC group seems to associate with the lower percentage of liver metastases.

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.

Abstract Background FOLFIRINOX (FFX) and Gemcitabine plus nab-paclitaxel (GnP) have been recommended as the first-line chemotherapy for metastatic pancreatic cancer (mPC). However, the evidence is lacking comparing not only two regimens, but also sequential treatment (FFX–GnP vs. GnP–FFX). Methods Data of 528 patients (FFX, n = 371; GnP, n = 157) with mPC were collected retrospectively. Propensity score matching was conducted to alleviate imbalance of the two groups. Overall survival (OS), progression free survival (PFS), and toxicity of patients were analyzed. Results In the whole population, OS (12.5 months vs. 10.3 months, P = 0.05) and PFS (7.1 months vs. 5.8 months, P = 0.02) were longer in the FFX group before matching and after matching (OS: 11.8 months vs. 10.3 months, P = 0.02; PFS: 7.2 months vs. 5.8 months, P <  0.01). For sequential treatment, OS and PFS showed no significant difference. Interruptions of chemotherapy due to toxicities were more frequent (6.8 vs. 29.3%, P <  0.001) in the GnP group, and cessation of chemotherapy showed a significant association with mortality (z = − 1.94, P = 0.03). Conclusions FFX achieved a longer overall survival than GnP in mPC, but not in the comparison for sequential treatment. More frequent adverse events followed by treatment interruptions during GnP might lead to a poor survival outcome. Therefore, FFX would be a better first-line treatment option than GnP for mPC.

TPS447 Background: Olaparib was approved in 2019 as maintenance therapy for g BRCA1/2+ metastatic pancreatic cancer (mPDA) patients (pts). The POLO trial showed an improvement in median progression free survival (mPFS) with olaparib compared to placebo (7.4 versus 3.8 months) for g BRCA1/2+ mPDA pts following either stable disease/response on first-line platinum chemotherapy. Preclinical studies have demonstrated that PARP inhibitors modulate the immune microenvironment by increasing genomic instability, PD-L1 expression and activating the immune inflammatory stimulator of interferon genes (STING) pathway. Several clinical studies in solid tumors have shown preliminary efficacy with the combination of PARP plus immune checkpoint inhibitors. Based upon these data, SWOG S2001 aims to further improve the PFS of g BRCA1/2+ mPDA pts. Methods: S2001 was developed in collaboration with the Alliance and was activated in SWOG in October 2020. mPDA pts with gBRCA1/2 mutations identified with standard of care germline genetic testing will be eligibleif no progression after receiving 4 to 6 months of platinum chemotherapy (FOLFIRINOX, FOLFOX or gemcitabine/cisplatin). Zubrod performance status (PS) 0 or 1 pts are eligible. Pts will be stratified according to first line chemotherapy, PS 0 versus 1, and disease status after first-line treatment. The primary objective of this study is to evaluate the PFS of mPDA pts treated with olaparib + pembrolizumab compared to olaparib alone as maintenance therapy. Based upon the POLO trial, we expect a mPFS of 7 months in the control arm. Targeting a mPFS of 11.7 months in the experimental arm (hazard ratio 0.6) and assuming 15 months follow-up, 80% power and a 1-sided alpha=0.10, this design requires 78 evaluable pts to be accrued over 3 years. Prospective serial blood samples will be collected to bank DNA and RNA for future correlative studies. Support:NIH/NCI grants U10CA180888 and U10CA180819. Clinical trial information: TBD.

Early tumor shrinkage (ETS) and depth of response (DoR) predict favorable outcomes in metastatic colorectal cancer. We aim to evaluate their prognostic role in metastatic pancreatic cancer (PC) patients treated with first-line modified-FOLFIRINOX (FOLFOXIRI) or Gemcitabine + Nab-paclitaxel (GemNab). Hence, 138 patients were tested for ETS, defined as a ≥20% reduction in the sum of target lesions’ longest diameters (SLD) after 6–8 weeks from baseline, and DoR, i.e., the maximum percentage shrinkage in the SLD from baseline. Association of ETS and DoR with progression-free survival (PFS) and overall survival (OS) was assessed. ETS was reached in 49 patients (39.5% in the FOLFOXIRI, 29.8% in the GemNab group; p = 0.280). In the overall population, ETS was significantly associated with better PFS (8.0 vs. 4.8 months, p < 0.001) and OS (13.2 vs. 9.7 months, p = 0.001). Median DoR was −27.5% (−29.4% with FOLFOXIRI and −21.4% with GemNab, p = 0.016): DoR was significantly associated with better PFS (9.0 vs. 6.7 months, p < 0.001) and OS (14.3 vs. 11.1 months, p = 0.031). Multivariate analysis confirmed both ETS and DoR are independently associated with PFS and OS. In conclusion, our study added evidence on the role of ETS and DoR in the prediction of outcome of PC patients treated with first-line combination chemotherapy.

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.

e16788 Background: Pancreatic cancer is the 4th leading cause of cancer-related death in the U.S. Metastatic pancreatic cancer has typically had a poor prognosis. However, the use of combination chemotherapy with novel agents have improved outcomes. First line therapy with either FOLFIRINOX (2011) or gemcitabine (gem)/nab-paclitaxel (2013) improved response rates (RR), progression-free survival (PFS) and OS versus (vs) gem alone. In 2015, second-line therapy with nanoliposomal irinotecan and fluorouracil (5FU) also improved RR, PFS, and OS vs 5FU. Since 2017, several newer agents have been approved for targeted patient populations – pembrolizumab for MSI-H/dMMR tumors, larotrectinib and entrectinib for NTRK gene fusion positive pts, and olaparib for germline BRCA-mutated pts. As more treatment (Tx) options become available, pts are more likely to receive Tx in later lines. A population-based study found that of mPC pts who completed 1st-line (1L) chemotherapy prior to December 31, 2014, 49% went on to receive 2nd-line (2L) Tx and 17% received 3rd-line (3L) Tx6. Methods: Prescribing patterns of 569 U.S.-based oncologists were studied using a validated, proprietary, case-based market research tool (Challenging Cases). Data were acquired using blinded, audience-response iPad technology at 8 live events during 2018-2019. Results: Estimate of mPC patients treated with 2L and 3L Tx in 2019 Estimates for mPC pts treated with 2L therapy rose from 2018 to 2019, with 46% treating > 60% of mPC patients with 2L in 2018 compared to 54% in 2019. Oncologists estimated median survivals to be 7.4 months (mos) from the regimens they prescribe in 1L, 4.3 mos in 2L, and 2.3 mos in 3L. Conclusions: With the addition of new and more effective treatments for mPC, more patients are treated in the 2L and 3L settings. However, oncologists may underestimate the survival expectation with novel agents or regimens, particularly in later lines of therapy. [Table: see text]
