TPS4666 Background: Second-line treatment options for advanced pancreatic adenocarcinoma are currently limited. Eryaspase, asparaginase (ASNase) encapsulated in red blood cells (RBCs) is an investigational product under development. Following infusion, asparagine and glutamine are actively transported into RBCs where they are hydrolyzed by the encapsulated ASNase. We have recently reported the outcome of a randomized Phase 2b study inpatients with advanced pancreatic cancer whose disease progressed following first-line treatment(NCT02195180). Eryaspase in combination with gemcitabine monotherapy or FOLFOX combination therapy improved overall survival (OS) and progression free survival (PFS). The safety profile of eryaspase was acceptable. The results of this Phase 2b study provided a rationale for initiating this confirmatory Phase 3 pivotal trial (TRYbeCA-1). Methods: TRYbeCA-1 is a randomized, open-label Phase 3 trial (N = ~500) of eryaspase combined with chemotherapy in patients with adenocarcinoma of the pancreas who have failed only one prior line of systemic anti-cancer therapy for advanced pancreatic cancer and have measurable disease. Patients are randomized in a 1:1 ratio to receive gemcitabine/Abraxane or irinotecan-based therapy (FOLFIRI [FOLinic acid-Fluorouracil-IRInotecan regimen] or irinotecan liposome injection/5-fluorouracil/leucovorin) with or without eryaspase, administered as IV infusion on Day 1 and Day 15 of each 4-week cycle. Key eligibility criteria include performance status 0 or 1; stage III-IV disease; documented evidence of disease progression; available tumor tissue; and adequate organ function. The primary endpoint is OS. Key secondary endpoints include PFS and objective response rate, safety, quality of life, pharmacokinetics and pharmacodynamics, and biomarker research. A hazard ratio in OS of 0.725 is being targeted which represents a conservative estimate based on the Phase 2b data and is viewed as being highly clinically relevant. An IDMC is established to review safety at regular intervals andto review efficacy data at the planned interim and final analyses. IDMC last reviewed the trial in October 2019 and suggested the trial continue as planned. Clinical trial information: NCT03665441 .

PurposeBoth gemcitabine (GEM) and fluoropyrimidines are valuable treatment for advanced pancreatic cancer. This open-label study was designed to compare the overall survival (OS) of patients randomly assigned to GEM alone or GEM plus capecitabine (GEM-CAP).Patients and MethodsPatients with previously untreated histologically or cytologically proven locally advanced or metastatic carcinoma of the pancreas with a performance status ≤ 2 were recruited. Patients were randomly assigned to GEM or GEM-CAP. The primary outcome measure was survival. Meta-analysis of published studies was also conducted.ResultsBetween May 2002 and January 2005, 533 patients were randomly assigned to GEM (n = 266) and GEM-CAP (n = 267) arms. GEM-CAP significantly improved objective response rate (19.1% v 12.4%; P = .034) and progression-free survival (hazard ratio [HR], 0.78; 95% CI, 0.66 to 0.93; P = .004) and was associated with a trend toward improved OS (HR, 0.86; 95% CI, 0.72 to 1.02; P = .08) compared with GEM alone. This trend for OS benefit for GEM-CAP was consistent across different prognostic subgroups according to baseline stratification factors (stage and performance status) and remained after adjusting for these stratification factors (P = .077). Moreover, the meta-analysis of two additional studies involving 935 patients showed a significant survival benefit in favor of GEM-CAP (HR, 0.86; 95% CI, 0.75 to 0.98; P = .02) with no intertrial heterogeneity.ConclusionOn the basis of our trial and the meta-analysis, GEM-CAP should be considered as one of the standard first-line options in locally advanced and metastatic pancreatic cancer.

4119 Background: Modified FOLFIRINOX (mFOLFIRINOX) consisting of 5-fluorouracil/leucovorin, irinotecan, and oxaliplatin has been assessed as second-line treatment of patients with advanced pancreatic cancer in retrospective and phase II studies. However, the result was not confirmed by randomized controlled trial. Methods: A randomized, open-label, phase III trial was conducted at 9 institutions in Korea. Patients with metastatic pancreatic adenocarcinoma (mPAC) and Eastern Cooperative Oncology Group performance status of 0-1 who failed to first-line gemcitabine-based chemotherapy were randomly assigned to receive mFOLFIRINOX or S-1. The primary endpoint was overall survival. Results: A total of 80 patients were enrolled from March 2017 to December 2019. The accrual of patients was early terminated due to clear difference of efficacy in the interim analysis and expectation of poor recruitment due to conflicting adjuvant regimens. Objective response and disease control rates were 15.4% vs. 2.4% ( p= 0.041) and 66.7% vs. 36.6% ( p= 0.007) in the mFOLFIRINOX and S-1 arms, respectively. The median progression-free survival was 5.2 and 2.2 months in the mFOLFIRINOX and S-1 arms, respectively ( p= 0.002). The median overall survival was 9.2 and 4.9 months in the mFOLFIRINOX and S-1 arms, respectively ( p= 0.048). The adjusted hazard ratio of the mFOLFIRINOX arm to the S-1 arm for overall survival was 0.402 (95% confidence interval 0.223-0.725, p= 0.002). All grade 3-4 adverse events occurred in 56.5% and 17.1% in the mFOLFIRINOX and S-1 arms, respectively ( p< 0.001). However, only one patient in each arm prematurely discontinued treatment due to toxicity and there was no treatment-related mortality in both arms. Minimally important differences in the health-related quality of life were not observed in both arms. Conclusions: mFOLFIRINOX as second-line treatment in mPAC patients failed to gemcitabine-based chemotherapy demonstrated a survival benefit versus S-1 alone with acceptable toxicities. Clinical trial information: KCT0003534.

405 Background: There is few data for effective second-line treatment in advanced pancreatic cancer, and most patients have poor performance status after progressive disease. We evaluated the efficacy, toxicity, and median dose intensity of oral chemotherapy, capecitabine, or TS-1 in gemcitabine-refractory advanced pancreatic cancer for second-line treatment. Methods: Patients who have progressive disease after first-line gemcitabine-based chemotherapy were retrospectively analyzed between Jan. 2011 and Nov. 2017. These patients were treated with capecitabine or TS-1 as second-line treatment. Capecitabine were administered as 2,500 mg/m2 divided dose on day 1-14, followed by one week rest. In TS-1 group, TS-1 was taken orally based on patient’s BSA (60mg twice daily in BSA > 1.5, 50mg twice daily in BSA 1.25-1.5, and 40mg twice daily in BSA < 1.25) through 28 days, by two week rest. Median dose intensity was compared by calculating a percent of target dose achieved in the average cycle for each patient. Results: Of the total 62 patients, 41 patients were treated with capecitabine and 21 patients were treated with TS-1. The median age was 61 years for the capecitabine group compared with 62 years for the TS-1 group. In capecitabine group, males were 56%, and in TS-1 group, males were 66%. 29% of capecitabine group received prior fluorouracil base therapy, and 47% of TS-1 group were receiving such therapy. The objective response rate was similar in the two groups: 12.2% with capecitabine and 4.8% with TS-1 (p = 0.358). There was no difference in median progression free survival between capecitabine and TS-1 (2.1 months vs. 2.7 months, p = 0.102), however, TS-1 group showed better median overall survival time than capecitabine group (6.9 months vs. 4.6 months, p = 0.048). Most of the adverse events were similar in both group, except that grade 3 or 4 mucositis was more common in TS-1 group. There was no significant difference in median dose intensity between two groups. (Capecitabine 91.5% vs. TS-1 90.1%, p = 0.216). Conclusions: Oral agents such as TS-1 or capecitabine can be second-line treatment for advanced pancreatic cancer patients with poor performance status after progression to gemcitabine-based regimen.

TPS600 Background: Pts with adv CCA have poor survival outcomes, and chemotherapy offers limited survival benefit (5-year survival rates, 5–10%; median overall survival [OS], 8–12 months). FGFR2 gene rearrangements are known to be early drivers of oncogenesis in ~15% of pts with intrahepatic (i) CCA. Futibatinib, an oral, highly selective, irreversible FGFR1-4 inhibitor has shown antitumor activity against a broad spectrum of FGFR-deregulated tumors in preclinical studies. In a previous study, futibatinib demonstrated clinical activity and tolerability in heavily pretreated pts with adv CCA harboring FGFR2 gene rearrangements. This phase 3 trial (FOENIX-CCA3) is designed to evaluate futibatinib vs gem-cis as 1L therapy for pts with adv iCCA harboring FGFR2 rearrangements. Methods: FOENIX-CCA3 is a multicenter, open-label, randomized phase 3 study that will be conducted in pts with metastatic or unresectable iCCA harboring FGFR2 rearrangements (assessed at screening by a central laboratory). Pts must have an ECOG performance status of 0 or 1 and should not have received previous systemic anticancer therapy for adv disease (adjuvant/neoadjuvant therapy ≥6 mo prior to randomization is permissible). Pts with clinically-significant alterations in calcium-phosphorus homeostasis or ectopic mineralization/calcification will be excluded. Approximately 216 pts will be randomized (1:1 ratio) to receive 20 mg futibatinib once daily until disease progression or other discontinuation criteria are met or gem-cis (on days 1 and 8 of a 21-day cycle) for 8 cycles or until disease progression, whichever occurs first. Pts will be stratified by prior surgical excision (yes vs no), geographic region, and locally adv vs metastatic disease. The primary endpoint is progression-free survival (PFS) assessed by independent central review (ICR). Secondary endpoints include objective response rate and disease control rate based on ICR, OS, PFS per investigator assessment, and safety. The anticipated start date is in April, 2020.

Objective. Comparing activity of 2 regimens combining oxaliplatin to bolus modulated fluorouracil as second line treatment in advanced pancreatic adenocarcinoma pretreated with gemcitabine-containing schedule. Methods. Forty eight patients with advanced pancreatic adenocarcinoma were randomly assigned to receive either FU 500 mg/m2 IV bolus weekly ×6 weeks plus leucovorin 500 mg/m2 IV weekly for 6 weeks during each 8-week cycle plus oxaliplatin 85 mg/m2 IV on weeks 1, 3, and 5 of each 8-week (FLOX) OR receive weekly intravenous infusions of oxaliplatin 40 mg/m2, 5-FU 500 mg/m2, and leucovorin 250 mg/m2 (3 weeks on, 1 week off). Results. Non progression(PR+SD) was found in 33.5% for first regimen and 29% for second regimen, and 37.5% had clinical benefit (FLOX regimen) compared to 50% in 3-weeks regimen. The median TTP was 3.9,4 months respectively. Median OS was 8, 9 months for both regimens. Only one case in 3-weeks arm suffered from grade IV diarrhea. Two cases > grade 2 neutropenia were observed; one in each treatment groups. Grade 3 anemia was recorded in 3 patients (2 in FLOX arm, one in 3-weeks arm). Conclusions. Both regimens showed encouraging efficacy, acceptable toxicity, and clinical benefit.

5566 Background: High EGFR expression occurs in 35–70% of primary ovarian tumors and is often associated with poor prognosis. This Phase II, open-label, non-comparative multicenter study investigated the efficacy and tolerability of gefitinib (Iressa) in combination with paclitaxel (P) and carboplatin (C) for second-line treatment of patients (pts) with ovarian, tubal or peritoneal adenocarcinoma. Methods: Women (>18 years) with platinum-resistant/refractory (relapsed <6 months after first-line platinum-based and P chemotherapy), or platinum-sensitive (relapsed >6 months) disease were enrolled. Pts received gefitinib (500 mg/day), P (175 mg/m2) and C (AUC 5) every 3 weeks for 6–8 cycles, after which pts could continue to receive gefitinib. The primary endpoint was objective response rate (ORR) assessed using RECIST or Rustin criteria. Results: Sixty-eight pts (26 resistant/refractory and 42 sensitive) were enrolled (median age [range]: 57 [34–72] years; ECOG performance status 0/1/2: 41/26/1). ORR and disease control rates were 19.2% and 69.2%, respectively, for resistant/refractory; and 61.9% and 81.0%, respectively, for sensitive pts (see table ). Grade 3/4 toxicities (in =10% pts) were neutropenia (59%), diarrhea (25%), leukopenia (22%), anemia (13%), and acne (13%). Two myelodysplastic syndromes (MDS) and one acute biphenotypic leukemia were observed during treatment. Another pt developed MDS 34 months after study treatment discontinuation. Conclusions: Gefitinib (Iressa) in combination with P and C has promising activity as second-line treatment for ovarian, tubal or peritoneal adenocarcinoma and is generally well tolerated. The hemopathies are under further investigation. [Table: see text] No significant financial relationships to disclose.

Angiogenic Therapy

TPS781 Background: The prognosis for patients with advanced pancreatic cancer (APC) is extremely dismal. First-line treatment for APC is gemcitabine/5-FU-based chemotherapy with no standard second-line treatment. Anti-angiogenic therapy combined with chemotherapy have showed its effects in improving the outcomes in a variety of cancers. Apatinib is an oral tyrosine kinase inhibitor that selectively targets VEGFR2. Some preclinical studies and several case reports showed the anti-tumor effect of apatinib in pancreatic cancer, but there is no evidence from clinical trial to confirm it. This study aims to evaluate the efficacy and safety of apartinib in combination with S-1 as the second-line therapy for patients with APC. Methods: In this open-label, single-arm, randomized phase II study, we will recruit 30 patients with pathologically proven advanced pancreatic cancer after the failure of first-line chemotherapy. All patients are aged 18-70 years with ECOG PS 0-2 and will receive apatinib at an initial dose of 500mg/d on a continuous basis, and oral S-1 (60mg/d for BSA < 1.25m2, 80mg/d for 1.25<BSA < 1.5m2, and 100mg for BSA >1.5m2, orally) twice a day on days 1-14 of a 21-day cycle. Primary endpoint is PFS. Secondary endpoints include OS, duration of response, ORR and DCR. The safety of apartinib + S-1 will be evaluated by CTCAE v4.0. Translational research will be performed in blood (before and on-treatment): cytokine panel to explore predictive and prognostic biomarkers. Clinical trial information: NCT03662035.
