Secondary Resectability

348 Background: Although there is a strong rationale for downstaging non-resectable pancreatic ductal adenocarcinoma (PDAC) for secondary resections by multi-agent chemotherapy, evidence from prospective randomized studies is missing. Methods: This prospective, randomized, open-label, phase II study aims to assess the activity, safety and feasibility of nab-paclitaxel/gemcitabine (nPG)- and FOLFIRINOX-based induction chemotherapy for patients (pts) with non-resectable PDAC. After two cycles of nPG pts are randomly allocated to receive either two additional cycles of nPG (arm A) or four cycles of FOLFIRINOX (arm B). Secondary resectability is assessed by exploratory laparotomy in all pts with at least stable disease (SD) after induction chemotherapy. The primary endpoint is to compare secondary complete macroscopic resection rates (R0/R1) in both arms. Results: We report the results of a planned interim (futility) analysis for efficacy data after at least 50 patients had completed induction chemotherapy and are evaluable for secondary surgical resection. Of pts who underwent randomization 42 pts were allocated to arm A and 44 pts to arm B, respectively. Disease control rate (DCR) after randomization was 93% in arm A and 89% in arm B. Explorative laparotomy was performed in 55% of randomized pts in arm A and 48% in arm B. Complete macroscopic resection (R0/R1) rate of randomized pts was 24% in arm A and 29% in arm B. For pts who received surgical exploration by laparotomy after completion of induction chemotherapy (n = 44) the complete macroscopic resection (R0/R1) rate was 43% in arm A and 62% in arm B. No new safety signals were identified thus far. Conclusions: nPG- and FOLFIRINOX-based induction chemotherapy approach revealed both effective and feasible in pts with LAPC supporting completion of patient recruitment in this trial. Interim results suggest promising secondary resection rates after multi-agent chemotherapy, especially when secondary resectability is assessed by surgical exploration. Clinical trial information: NCT02125136.

TPS4160 Background: FOLFIRINOX (5-fluorouracil [5FU], folinic acid [FA], irinotecan [Iri], and oxaliplatin [Ox]) is a standard 1st-line treatment in fit Pts with aPDAC. Anti-PD-1/PD-L1 as single agents have failed in PDAC so far and new combination immunotherapies are needed. Tedopi (OSE2101) is a multiple neoepitope vaccine restricted to HLA-A2 positive Pts, targeting 5 tumor-associated antigens (CEA, HER2, MAGE2, MAGE3, TP53) that are frequently expressed in PDAC. This study aims to assess the efficacy and safety of Tedopi alone and in combination with anti-PD-1 nivolumab, or FOLFIRI as maintenance therapy in Pts with aPDAC after FOLFIRINOX induction CT. Methods: TEDOPaM - PRODIGE 63 is a 3-arm, Fleming 2-stage, open-label, randomized, non-comparative phase II study. 156 Pts with locally advanced or metastatic, pathologically proven PDAC; ECOG performance status 0-1; HLA-A2 genotype; controlled disease (objective response or stable disease) after 8 cycles of (modified) FOLFIRINOX; and adequate organ functions, are randomized (1:1:1, stratified on center, tumor stage, and best response to FOLFIRINOX) into 3 arms: Clinical trial information: NCT03806309. In Arms B and C, FOLFIRI is reintroduced at disease progression or unacceptable toxicity. Primary endpoint: overall survival rate at M12. Secondary endpoints: progression-free survival (CT-scan Q8W), duration of disease control, safety, objective response rate, RECIST v1.1/iRECIST comparison, HRQoL (EORTC QLQ-C30), Q-TWiST. An interim analysis is planned after inclusion of 20 Pts in each arm. Translational research will be performed on tumor tissue (initial FFPE biopsy and optional re-biopsy at inclusion): RNAseq (cancer and stroma), mutation burden, MMR status, immune infiltrates; and in blood (before and on-treatment): cytokine panel, PBMC phenotyping, vaccine-antigen specific T-cells, TCR repertoire, and extracellular vesicles, to explore biomarkers and pharmacodynamics effects of Tedopi ± nivolumab. Enrollment (12th Feb 2019): 1. ClinicalTrials Registration: NCT03806309.[Table: see text]

Abstract Background: Immune Modulation and Gemcitabine Evaluation-1, a randomised, open-label, phase II, first-line, proof of concept study (NCT01303172), explored safety and tolerability of IMM-101 (heat-killed Mycobacterium obuense; NCTC 13365) with gemcitabine (GEM) in advanced pancreatic ductal adenocarcinoma. Methods: Patients were randomised (2 : 1) to IMM-101 (10 mg ml−l intradermally)+GEM (1000 mg m−2 intravenously; n=75), or GEM alone (n=35). Safety was assessed on frequency and incidence of adverse events (AEs). Overall survival (OS), progression-free survival (PFS) and overall response rate (ORR) were collected. Results: IMM-101 was well tolerated with a similar rate of AE and serious adverse event reporting in both groups after allowance for exposure. Median OS in the intent-to-treat population was 6.7 months for IMM-101+GEM v 5.6 months for GEM; while not significant, the hazard ratio (HR) numerically favoured IMM-101+GEM (HR, 0.68 (95% CI, 0.44–1.04, P=0.074). In a pre-defined metastatic subgroup (84%), OS was significantly improved from 4.4 to 7.0 months in favour of IMM-101+GEM (HR, 0.54, 95% CI 0.33–0.87, P=0.01). Conclusions: IMM-101 with GEM was as safe and well tolerated as GEM alone, and there was a suggestion of a beneficial effect on survival in patients with metastatic disease. This warrants further evaluation in an adequately powered confirmatory study.

15122 Background: Despite the use of 5-FU based chemoradiotherapy (CRT) over the past decades, prognosis of patients with LAPC remains dismal. To deliver more efficient systemic treatment earlier and reduce toxicity of CRT, we designed a treatment protocol consisting of induction (IND) chemotherapy with FDR gemcitabine (GEM) and cisplatin (CDDP), followed by CRT with capecitabine (CAP) in LAPC. Methods: Eligible patients had unresectable, histologically confirmed adenocarcinoma of pancreas, ECOG PS of 0–2, and no prior chemo- or radiotherapy for this phase II study. Patients received FDR GEM 1000 mg/m2 (D1,8) and CDDP 60 mg/m2 (D1) every 3 weeks for 3 cycles. Patients without disease progression subsequently received CRT of 55.8 Gy in 31 fractions concurrently with CAP, 650 mg/m2 given twice daily without drug holidays. Four weeks after CRT, FDR GEM 1000 mg/m2 was given on day 1, 8 every 3 weeks for 3 cycles. Time to progression was the primary endpoint. Results: Between Jan 2005 and Nov 2006, 21 patients were enrolled (median age 59, M/F: 13/8, ECOG PS 0/1: 3/18). Two patients withdrew consent after 1st and 2nd cycle and remaining 19 patients completed all three cycles of IND chemotherapy, with three (15.8%) out of 19 evaluable patients achieving partial response (0 CR, 3 PR, 14 SD, 2 PD). All 17 patients completed CRT with mean radiation dose of 55.4 Gy. Further four patients progressed during CRT, while one additional patient achieved partial response. As of Jan 2007, 5 patients died and 12 patients showed tumor progression. Median TTP was 12.5 mo (95% CI: 4.2–20.8) and median survival was not reached with median follow up duration of 9.7 months. Grade III/IV toxicities included neutropenia (38.1%/9.5%), thrombocytopenia (4.8%/0%), and anemia (14.3%/0%) during IND phase. Toxicites were generally mild during CRT phase with grade III neutropenia and diarrhea occurring in one and two patients, respectively. One patient died of neutropenic sepsis after 3rd cycle of IND chemotherapy. Conclusions: FDR GEM-CDDP induction chemotherapy followed by CAP-RT and maintenance FDR GEM is feasible and active with promising TTP of 12.5 months. Enrollment continues till reaching target accrual of 37 patients. No significant financial relationships to disclose.

256 Background: Although FOLFIRINOX is superior to gemcitabine in MPC, the regimen is associated with significant toxicities (Conroy et al. N Engl J Med 2011;364:1817). In our prior retrospective analysis, efficacy was not compromised by dose attenuations of FOLFIRINOX (Gunturu et al. Med Oncol 2013;30:361). Based on this analysis, we are conducting a prospective phase II open label study to evaluate the efficacy & tolerability of mFOLFIRINOX in pts with advanced pancreatic cancer (PC). Methods: Previously untreated pts with MPC or LAPC received mFOLFIRINOX with 25% dose reductions of irinotecan & bolus 5-FU given every two wks until progression, unacceptable toxicity, or surgical resection. All pts received prophylactic pegfilgrastim. FDG-PET scans were obtained at baseline & after 2 cycles. CAT scans were obtained after every 4 cycles. Toxicities & response rate (RR) were compared to historical data reported by Conroy. Results: 53 pts with ECOG PS ≤1 have been enrolled to date between 11/11 and 08/13, Pt characteristics: LAPC 22; MPC 31; median age 62 yrs (range 46-86); male 30. Median # of cycles was 8 (range 1-21). Grade 3/4 toxicities were: anemia, febrile neutropenia (FN) & peripheral sensory neuropathy (PSN) – 3.8% each; ALT increased & thromboembolism – 5.7% each; diarrhea 7.5%; fatigue 11.3%; neutropenia 17%; thrombopenia 11.3% & vomiting 1.9%. Anemia ( p< 0.04), FN (p<0.04), PSN (p<0.04) and vomiting (p<0.02) were significantly decreased compared to historical data (Conroy). Response by RECIST (CR+PR) in 26 evaluable pts with MPC was 29% (0 CR, 9 PR, 14 SD, 3 PD) & similar to historical data (31.6%; p 0.85). 6/13 evaluable pts with LAPC underwent resection (46%).13/36 pts evaluable for PET response had a >50% decrease in SUV(max)(36%). Evaluation for OS & PFS is ongoing. Conclusions: Findings from our interim analysis suggests that mFOLFIRINOX, given along with prophylactic pegfilgrastim is associated with a similar RR and improved tolerability compared to full dose FOLFIRINOX in advanced PC. In pts with LAPC, neoadjuvant FOLFIRINOX appears to have substantial activity with 46% of evaluable pts undergoing resection. Accrual will continue to reach a goal of 70 pts. Clinical trial information: NCT01523457.

366 Background: Recent improvements in chemotherapy for initially unresectable pancreatic ductal adenocarcinoma (UPDAC) occasionally show remarkable antitumor effect and lead to conversion surgery (CS). However, the optimal indication and clinical impact of CS remains unknown. We have recently developed a new regimen consisted of biweekly S-1, oxaliplatin, and irinotecan (SOXIRI). In this regimen, we used S-1 in alternate-day administration instead of 5-FU, that can be more feasible than FOLFIRINOX. The aim of this study was to evaluate the clinical impact of CS after SOXILI treatment for initially UPDAC. Methods: We conducted an open-label, single-arm, phase II study that was carried out at Nara Medical University and Kansai Medical University in Japan. Patients with untreated metastatic and locally advanced PDAC were enrolled. They received 80 mg/m2 twice a day of S-1 for 2 weeks in alternate-day administration, 150 mg/m2 of irinotecan on day 1, and 85 mg/m2 of oxaliplatin on day 1 of a 2-week cycle. Results: The 35 enrolled patients received a median of six (range: 2-15) treatment cycles. The RR was 22.8%; median OS, 17.7 months; and median PFS, 7.4 months. Major grade 3 or 4 toxicity included neutropenia (54%), anemia (17%), febrile neutropenia (11%), anorexia (9%), diarrhea (9%), and nausea (9%). Twenty-three out of 35 patients of UR-PDAC were unresectable locally advanced pancreatic cancer (UR-LAPA). Seven out of 23 patients with UR-LAPA underwent CS. Distal pancreatectomy with celiac axis resection was performed in three patients, central pancreatectomy was performed in one patient. Pancreatoduodenectomy (PD) was performed in two patients, and PD with portal vein resection in one patient. Two out of seven patients had postoperative complications. One case had grade B pancreatic fistula, and the other case underwent cholecystectomy due to acute cholecystitis. The median OS in patients who received CS was 31.4 months. Conclusions: SOXIRI regimen has shown promising clinical efficacy with acceptable tolerability in patients with unresectable pancreatic cancer. Furthermore, it may be a potent first-line treatment when considering conversion surgery. Clinical trial information: UMIN000014339.

Abstract Background Chemoradiotherapy is a treatment option for locally advanced pancreatic cancer. However, the efficacy of induction chemotherapy prior to chemoradiotherapy is uncertain. The aim of this randomized, multicentre phase II study is to evaluate the efficacy and safety of chemoradiotherapy with and without induction chemotherapy to determine the significance of induction chemotherapy. Methods Patients with locally advanced pancreatic cancer were randomly assigned to the chemoradiotherapy arm (Arm A) or induction chemotherapy followed by the chemoradiotherapy arm (Arm B). Patients in Arm A underwent radiotherapy with concurrent S-1. Patients in Arm B received induction gemcitabine for 12 weeks, and thereafter, only patients with controlled disease underwent the same chemoradiotherapy as Arm A. After chemoradiotherapy, gemcitabine was continued until disease progression or unacceptable toxicity in both arms. The primary endpoint was overall survival. Results Amongst 102 patients enrolled, 100 were eligible for efficacy assessment. The probability of survival was greater in Arm B in the first 12 months, but the trend was reversed in the following periods (1-year survival 66.7 vs. 69.3%, 2-year survival 36.9 vs. 18.9%). The hazard ratio was 1.255 (95% confidence interval 0.816–1.930) in favour of Arm A. Gastrointestinal toxicity was slightly more frequent and three treatment-related deaths occurred in Arm A. Conclusions This study suggested that the chemoradiotherapy using S-1 alone had more promising efficacy with longer-term survival, compared with induction gemcitabine followed by chemoradiotherapy for locally advanced pancreatic cancer. Clinical trial registration The study was registered at the UMIN Clinical Trials Registry as UMIN000006811.
