e15594 Background: The addition of E to G results in improved survival for patients(pts) with locally advanced and metastatic pancreatic cancer. Many pancreatic tumors have constitutively activated ras/raf pathways and overexpress VEGF. Sorafenib, a multitargeted tyrosine kinase inhibitor which targets VEGR 1–3, PDGFR-α and β and the RAF/MEK/ERK pathway, when combined with G and E may synergize with these agents resulting in a more complete blockade of the signal transduction cascade in pancreatic cancer growth and progression and therefore improve outcome. Methods: Pts with previously untreated, histologically confirmed, unresectable pancreatic adenocarcinoma, ECOG PS 0–1, and adequate organ function were eligible and received G 1,000 mg/m2 over 30 min weekly × 3 every 4 weeks. E 150 mg PO daily and S 400 mg PO bid were given continuously. CT scans were performed every 2 cycles (8 weeks). Endpoints included safety and tolerability of the novel combination, PFS at 4 months, response rate, and OS. Results: Between 9/07–12/08 19 pts were enrolled with a median age 59 (range 45- 75), M/F 13/6, PS (0/1) 14/5. All 19 had metastatic disease. 17 pts are evaluable for toxicity and efficacy. The median number of cycles on treatment was 2 (range 1–10). The most common grade (gr) 3 toxicities were thrombocytopenia (24%), venous thrombosis (12%), and hyperbilirubinemia (12%). The most common gr 4 toxicity was infection (12%). 1 pt each experienced gr 3 HFSR, gr 3 diarrhea, gr 3 bleeding (epistaxis) and 1 had a non-fatal bowel perforation. There was 1 PR and 6 SD for an overall RR of 6% and a DCR of 41%. Conclusions: The combination of G and E plus S in the treatment of advanced pancreatic cancer is a well tolerated regimen without significant increased toxicity as compared to gemcitabine alone, except for very manageable cutaneous reactions. Further follow up is required to determine the combination's efficacy, though some patients have achieved prolonged disease stabilization.

266 Background: Addition of erlotinib (E) to gemcitabine (G) results in improved OS for patients (pts) with advanced pancreatic cancer. Many pancreatic tumors have constitutively activated ras/raf pathways and overexpress VEGF. Sorafenib (S), a multitargeted tyrosine kinase inhibitor, including VEGR 1-3, PDGFR-α and β and the RAF/MEK/ERK pathway, when combined with G and E may synergize, resulting in a more complete blockade of the signal transduction cascade in pancreatic cancer growth and progression, and improved outcome. Methods: Pts with previously untreated, histologically confirmed, unresectable pancreatic adenocarcinoma, PS 0-1, and adequate organ function were eligible and received G 1,000 mg/m2 over 30 min qw x 3 every 4w. E 150 mg PO daily and S 400 mg PO bid were given continuously. CT scans were performed every 2 cycles (8w). Primary endpoint included PFS at 4 mos and secondary endpoints included safety and tolerability of the novel combination, RR, and OS. Results: 45 pts enrolled, 44 evaluable for toxicity(1 not treated), and 30 evaluable for response. Median age was 64 (45-84), 32 males (71%), 43 (96%) had metastatic disease, PS was 0 in 26 (58%). Median number of cycles was 2 (0-10). Grade (gr) 3 toxicity included: thrombocytopenia 5; diarrhea 4; vomiting 4; HFS, hyperbilirubinemia, hyperglycemia and SOB each 3 pts; 1 bowel perforation and 1 epistaxis. Gr 4 toxicity included 1 each: bowel perforation, GI bleed, transaminitis, hyperglycemia and sepsis with hypotension. 2 patients only required dose reduction of S for HFS. There were 2 PR (7%), 13 SD (43%), overall RR of 7% and DCR of 50%. Median TTP 111 days (95% CI = 53-175) and median OS 195 days (144-290). PFS at 16 weeks was 49%, just reaching statistical significance. Conclusions: The combination of G and E plus S in the treatment of advanced pancreatic cancer is a well tolerated regimen without significant increased toxicity as compared to G alone, except for very manageable cutaneous reactions. While the primary endpoint met our pre-determined criteria (compared with NCIC PA.3), this study does not suggest a major benefit for addition of S to G-E when compared to published data.

Combination Strategy

Abstract Background There have not been standard second-line or maintenance regimens with definite survival benefits so far for patients with pancreatic carcinoma who have lost the opportunity of curable resections or failed first-line chemotherapy. Anlotinib, a potent small-molecule tyrosine kinase inhibitor, exhibits anti-angiogenic and anti-tumour effects by specifically binding to multiple targets such as VEGFR, FGFR, PDGFR, c-Kit and Ret. Toripalimab, a novel anti-PD-1 mAb, has been proved to significantly prolong progression-free survival (PFS) and overall survival (OS) in various solid tumours with manageable toxicities when combining with cytotoxic chemotherapy. We design this study to assess the combination of anlotinib, toripalimab and nab-paclitaxel as a second-line or maintenance therapy for locally advanced pancreatic cancer (LAPC) or metastatic pancreatic cancer (MPC). Patients and Methods: This is an open-label, non-randomized, single-arm phase Ⅱ study, aimed at evaluating the efficacy and safety profile of the above-mentioned combination strategy in first-line therapy-failed LAPC or MPC. Totally 53 patients are to be enrolled and receive anlotinib (12 mg, po. qd.) plus toripalimab (240 mg, ivgtt. q3w.) and nab-paclitaxel (125 mg/m2, ivgtt, d1, d8) every 3 weeks as a cycle until disease progression or intolerable adverse events. The primary endpoint is PFS. Secondary end points include OS, disease control rate (DCR), object response rate (ORR), quality of life (QoL) and safety. Enrollment started in April 2021, and follow-up will be finished in April 2023. Discussion and Significance: Combination of anlotinib, toripalimab and nab-paclitaxel may promote vessel normalization and drug delivery, and activate the immune response, thus exerting synergistic anti-tumour effects and counteracting the immunosuppressive microenvironment of pancreatic cancer. As the first intending to assess this combination in pancreatic cancer, this study will provide comprehensive evidence for second-line or maintenance therapy of LAPC and MPC.

490 Background: Conroy et al. (N Engl J Med 364:1817–1825, 2011) have shown significantly better overall survival with FOLFIRINOX compared to gemcitabine in metastatic pancreatic cancer patients (MPC). However, given the toxicity associated with FOLFIRINOX treatment, different institutions have adapted varying modifications to the original regimen. Methods: We performed a retrospective review of dose, toxicity, and efficacy of FOLFIRINOX in patients with unresectable locally advanced pancreatic cancer (LAPC) and MPC treated between Jan 2011 and Dec 2015 at University of Vermont Medical Center. Results: 43 patients were treated, of which 33 did not receive any prior treatment (6 LAPC, 27 MPC). 41 patients received dose attenuation with 1st cycle. Median relative dose of irinotecan, oxaliplatin and 5-FU were less than reported by Conroy (69 vs. 81%, 70 vs. 78% and 71 vs. 82%). Median number of treatment cycles 7.8 (range 1 to 41). Median progression free survival in our MPC cases compared to Conroy’s data was 5.7 vs. 6.4 months; overall survival at 6 and 12 months were 78 vs. 75.9% and 41 vs. 48.4% respectively. Grade ¾ toxicities were less, including neutropenia (p<0.001), fatigue (p =0.01) and neuropathy (p=0.04). One patient had grade 3 pneumonitis related to oxaliplatin. Conclusions: Our findings suggest that dose attenuation of 5-FU, irinotecan and oxaliplatin improve tolerability with fairly similar outcome as reported by Conroy et al. [Table: see text]

15058 Background: Imexon for inj. (Amplimexon®, AMP) is an aziridine-containing iminopyrrolidone which causes G2 arrest, accumulation of reactive oxygen species, and induction of apoptosis in pancreatic cancer cells. AMP demonstrated synergy with gemcitabine (GEM) in preclinical pancreatic cancer models. This phase I study of AMP plus GEM was undertaken to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT). Secondary endpoints were pharmacokinetics for both agents (PK) and tumor response. Methods: Patients (pts) with previously untreated advanced pancreatic adenocarcinoma received one of two dosing regimens. The first 19 received 30 minute AMP IV days 1–5 and 15–19 followed by 30 minute GEM IV days 1, 8 and 15 Q4 wks (Regimen A). Dosing was modified after 19 pts to administer both AMP and GEM over 30 minutes days 1, 8 and 15 every 4 weeks (Regimen B). Dose levels (AMP/GEM, in mg/m2) for Regimen A: 200/800, 280/800, 200/1000, and 280/1000, and for Regimen B: 280/1000, 335/1000, 390/1000, 540/1000, and 750/1000. The current cohort is 1000/1000. Pts were assessed for response after cycles 2, 5 and 8. PK and pharmacodynamic (plasma thiol depletion) measurements were obtained during cycle one. Results: Forty-six pts have been treated to date, with 36 having complete toxicity data and evaluable. Pt characteristics: M/F (24/12), Age (mean 60.4 years, range 43–75), ECOG PS 0/1 (56%, 44%), metastatic/locally advanced (91%, 9%). The 36 pts have completed 122.5 cycles of therapy (median 2, range 0.5–12). Common toxicities: anemia (77%), fatigue (71%), nausea (60%), fever (54%), and leukopenia (54%). DLT were 1/6 at 280/1000 (Regimen A - febrile neutropenia), 1/6 at 280/1000 (Regimen B - gr 3 hypotension, gr 4 renal failure), and 1/9 at 390/1000 (gr 3 hyperbilirubinemia). Accrual continues at 1000/1000. Of 36 pts, 4 have had partial responses and 14 stable disease. PK and plasma thiol analysis are ongoing. Conclusions: Imexon can be administered safely with full dose gemcitabine. Accrual continues to define the combination MTD. The response rate in this phase I study compares favorably with historical gemcitabine monotherapy, and further phase II evaluation of this combination in advanced pancreatic cancer is warranted.

4519 Background: Gemcitabine (G) is standard for metastatic pancreatic cancer (PC), with median survivals of 6 months (m). Second cytotoxic or biologic agents do not substantially advance survival. EGFR is expressed on PC and a phase II trial of G plus cetuximab (C) resulted in favorable 1 year survival. A phase II trial of irinotecan/docetaxel (I/D) chemotherapy reported a median survival for metastatic patients (pts) of 9 m. We conducted this randomized phase II trial to confirm the activity of this non-G regimen, and determine whether combining it with C was feasible and active. The primary endpoint was response. Methods: Pts required histologic confirmation of adenocarcinoma of the pancreas, evidence of distant metastases, ECOG PS 0–1, normal bilirubin, written informed consent, and were randomly assigned to Arm A (N=47) or B (N=45). Imaging with CT or MR within 4 weeks (wk) was used for tumor measurement. Dexamethasone was given 12 hours (h), 1 h before and 12 h after chemotherapy. Pts on Arm A received D 35 mg/m2 over 1 h and I 35 mg/m2 over 30 minutes weekly x 4 in a 6 wk cycle. Pts on Arm B received the same therapy, but C (loading dose 400 mg/m2 wk 1, 250 mg/m2 weekly thereafter) was given before D. Pts not receiving therapeutic anticoagulation received enoxaparin 40 mg per day. Pts were restaged (RECIST) after 2 cycles. Results: Median age Arm A: 59.9, Arm B: 60.2 years. Arm A 55% male, 32% PS 0, 97% EGFR immuno+. Arm B 84% male, 42% PS 0, 97% EGFR +. Median number of cycles for each arm 2 (1 -10). >4 cycles were delivered to 10.5% of pts Arm A, 20.9% Arm B. Grade ¾ neutropenia 26% Arm A, 33% Arm B. Grade 3 nausea 28% Arm A, 18% Arm B; Grade ¾ diarrhea 33% Arm A, 44.4% Arm B. 1 treatment-related death per arm. Median overall survival (OS), with 70.2% of pts known to have died, 6.5m [(95% CI (4.8, 8.6)] in Arm A. With 86.7% of pts known to have died in Arm B, OS 7.4 m [95% CI (4.4, 10.7)]. Response/progression data will be available at time of presentation. Conclusions: Weekly I/D ± C is associated with high rates of grade ¾ neutropenia/diarrhea. Median survival is 6.5m for I/D and 7.4m for I/D/C. Non-G containing therapy is active in metastatic PC. [Table: see text]

195 Background: More than 80% of patients with pancreatic cancer present with locally advanced or metastatic disease and have a median survival of only 6 months. Immunotherapy approaches may improve outcomes. Gene Mediated Cytotoxic Immunotherapy (GMCI) is an approach that generates a systemic anti-tumor vaccine effect through intra-tumoral delivery of an adenoviral vector expressing the HSV-thymidine kinase gene (AdV-tk) followed by anti-herpetic prodrug and synergy with chemoradiation. The mechanisms of action involve tumor cytotoxicity, activation of antigen presenting cells and stimulation of systemic anti-tumor T-cell immunity. Safety with potential efficacy has been demonstrated in multiple clinical studies. This is the first application of GMCI in pancreatic cancer. Methods: This study evaluated 4 dose levels of AdV-tk (3x1010 to 1x1012 vector particles) injected into locally advanced tumors via EUS or CT-guidance before and during week 3 of standard 5-FU-chemoradiation. Valacyclovir (Valtrex, GSK) prodrug was given for 14 days after each of 2 AdV-tk injections. Results: The study completed accrual with 13 patients enrolled and 12 completing therapy with 3 at each of the 4 dose levels. One patient refused further participation during course 1 after recovering from azotemia. Median age was 64 years (range 55-81) and median baseline CA19-9 was 1634 U/ml. No dose limiting toxicities and no injection related complications occurred. Possibly related grade 3-4 toxicities, all of which were transient, included dehydration, azotemia and worsening elevation of bilirubin and AST. Kaplan-Meier estimated median survival is 12.2 months with 6 patients still alive at 8-20 months. Two patients achieved a partial response by RECIST criteria. One occurred in week 6 despite discontinuing 5-FU/radiation during week 1. The other had gradual decrease of a 7 cm tumor over 11 months. Serum CA19-9 levels decreased in 8/8 evaluable patients by 32-91% at 3 months after treatment initiation. Conclusions: AdV-tk can be safely injected into pancreatic tumors and combined with standard chemoradiation. Early results are highly encouraging and justify further evaluation in a phase II study.

Abstract Purpose: The presence of a sarcopenia adversely affects the prognosis of patients with pancreatic cancer. There is an emerging role for using computed tomography (CT) to calculate skeletal muscle index (SMI) and the presence of sarcopenia. The aim of this study was to assess if detecting ‘digital sarcopenia’ is feasible and can contribute to the management of patients with locally advanced pancreatic cancer (LAPC).Methods: Patients diagnosed with LAPC referred for endoscopic ultrasound guided biopsy (EUS-B) by our regional cancer network were identified. Age, body mass index (BMI), and Eastern Cooperative Oncology Group performance status (ECOG-PS) was noted. CT images were analysed for SMI and the presence of sarcopenia. Decision outcomes on receiving chemotherapy or not were collected from the regional oncology database. Results: In total 51/204 (25%) patients with LAPC who underwent EUS-B were not given chemotherapy and received BSC only. The prevalence of sarcopenia (p=0.0003), age ≥ 75 years old (p=0.03) and ECOG-PS 2-3 (p=0.01) were significantly higher in the patents receiving BSC only. Logistic regression analysis demonstrated that SMI was the only independent associated factor identifying patients with LAPC who were treated with BSC only and not chemotherapy after adjusting for age and ECOG-PS. Conclusion: Our study has shown that digital skeletal muscle analysis at the time of a diagnostic CT for patients with pancreatic cancer is feasible and can detect sarcopenia and malnourished patients who are much less likely to take up chemotherapy. These patients could be triaged to oncology assessment prior to EUS-B to avoid unnecessary investigations.

4116 Background: Virulizin (V) is a novel antitumor immune modulator that improves survival in pancreatic cancer patients (pts) as monotherapy. A double-blind, multicenter, randomized, phase III study was conducted to evaluate the survival benefits and safety of V in combination with gemcitabine (G) in pts with advanced pancreatic cancer. Methods: Chemo-naive pts with locally advanced or metastatic pancreatic cancer with ECOG Performance Status (PS) of 0, 1 or 2 were enrolled. Pts were randomized to receive intramuscular injections of either V or placebo (P) 3 times weekly + G (1,000 mg/m2 weekly ×7 with 1 week rest, then weekly ×3 q4w). Randomization was stratified according to ECOG PS (0 or 1, and 2) and extent of disease (locally advanced and metastatic). Pts who showed no clinical benefit or were intolerant to G entered 2nd-line therapy (stage 3), in which pts continued to receive either V or P alone or with 5-FU, or best supportive care. The primary endpoint was survival, defined as time from baseline/treatment day 1 to time of death from any cause. Results: The intent to treat (ITT) population comprised 434 pts, of which 377 were efficacy evaluable (EE). Median overall survival for V + G was 6.3 months for the ITT population (6.8 months for EE pts) and 6 months for P + G for both ITT and EE pts. While differences in survival times were not statistically significant, exploratory analysis showed encouraging results in specific subgroups treated with V + G ( table ). Importantly, a significant difference was found in stage 3 pts who received V in a salvage setting compared to pts who received P. Conclusions: Pancreatic cancer pts with either low ECOG PS or metastatic cancer showed a survival benefit when treated with V + G, which was significant in pts who continued to receive V as a salvage therapy. Further studies in these targeted patient populations are being considered. [Table: see text] No significant financial relationships to disclose.

15029 Background: Docetaxel and Capecitabine in combination are synergistic in preclinical models. The role of second line chemotherapy in pancreatic cancer is palliative and the role under investigation. Methods: Capecitabine 800 mg/m2 PO bid on days 1–14 in combination with docetaxel 30 mg/m2 IV on days 1 and 8 of each 21-day cycle were given to patients with advanced and metastatic pancreatic cancer previously treated with Gemcitabine. A 3-stage sequential design phase II trial was used with early stopping rules for efficacy at 13 and 26 enrolled patients Results: Twenty-four patients are evaluable for toxicity and evaluable for response. Thirteen are females and 11 male patients. Median age was 65 years. ECOG PS was as follows: PS 0: 2 patients; PS 1: 15 patients; PS 2: 5 patients. Three patients achieved a PR, with a RR of 12.5%. Stable disease for 2 or more cycles was observed in 70.8% of patients (n=17). 45 % (n=11) of patients had a 50% or more decrease in CA 19–9 levels. Treatment was well tolerated with no toxic deaths. Grade III and IV toxicities consisted of fatigue in 4 pts (17%); hand-foot syndrome in 4 patients (17%); diarrhea, anemia and mucositis in 2 patients (9%) and peripheral neuropathy in one patient (4%) Conclusions: The combination of capecitabine and docetaxel is active and well tolerated in pancreatic cancer previously treated with gemcitabine based-therapy. Enrollment continues. [Table: see text]

e21093 Background: Advanced pancreatic cancer has a poor prognosis with a median survival of 6-10 months. There is a need for early non-invasive assessment of treatment response. We evaluated FLT PET-CT combined with a kinetic spatial filtering method (FLT-PETKSF) for detecting response to gemcitabine-based chemotherapy in advanced pancreatic cancer. Methods: Dynamic FLT PET-CT data were collected from patients with confirmed locally advanced or metastatic pancreatic cancer before and 2 weeks after the first cycle of chemotherapy. Changes in tumor FLT-PET variables with treatment were determined. Standardized uptake value (SUV) reduction of 18% was taken as cut-off for response. Voxel quantification of each tumor volume was performed on the filtered data. Each voxel-intensity was normalised by injected dose, body weight and decay corrected to obtain the SUV for the voxel. Changes in high intensity voxels (HiVox: SUV ≥ 2) - were computed. Results: Results of the first 5 patients are discussed. There were 4 primary and 9 metastatic tumors. FLT-PETKSF improved tumor-to-background ratio and enabled visualisation of all the primary and metastatic tumors. The mean (± SD) average and maximum SUV at 60 min (SUV60, av & SUV60, max) of the primary lesions was 2.10 (±0.38) & 4.85 (±1.55) and that of the metastatic lesions was 3.74 (±1.49) & 6.90 (±2.05) respectively. The mean (± SD) percentage reduction in the SUV60, av & SUV60, max, HIVox was 26 (±44), 18 (±38) and 23 (±50) respectively. The changes in the voxel occurrences correlated strongly with the changes in both SUV60, av & SUV60, max (Pearson r-0.9, p=0.001) .Overall, there were 2 partial responders and 3 with stable disease. These responses concurred with response evaluation on mid-treatment CT scan. Conclusions: FLT-PET and FLT-PETKSF enables visualisation of the pancreatic tumors and the liver metastases, and could be used to monitor response to therapy.
