4009 Background: FOLFIRINOX significantly increases survival in metastatic PC compared to gemcitabine, but its use is limited to selected pts, due its high toxicity. In the majority of cases, gemcitabine (gem) remains the mainstay of palliative treatment, although its modest impact on survival and disease progression. The addition of the EGFR tyrosine kinase inhibitor erlotinib prolonged median survival for only 2 weeks.This study was aimed to investigate the effect of adding Nimotuzumab (nimo), an anti-EGFR monoclonal antibody, to first-line gemcitabine, in PC. Methods: Pts with previously untreated, unresectable, locally-advanced or metastatic PC were randomly assigned to receive gem: 1000 mg/m2/ 30-min iv once weekly (d1, 8, 15; q28) and nimo: fixed dose of 400 mg once weekly as a 30-min infusion, or placebo, until progression or unacceptable toxicity. Primary endpoint was overall survival (OS) in the intention-to-treat (ITT) population. Secondary endpoints included PFS, safety, objective response rate (ORR), QoL. Results: Between 9/2007- 10/2011 a total of 192 pts were randomized (average age 63.6 ±10 years; 60% male; 69% ECOG PS 0), and 186 were evaluable at the ITT analysis. One-year OS was 19.5 % with gem+placebo and 34.4% with gem+nimo (HR=0.69; p=0.034). Median OS and PFS were 6.0 mo in the gem+placebo group, vs. 8.7 mo in gem+nimo (HR=0.83; p=0.21), and 3.7 vs. 5.4 mo, respectively (HR=0.73; p=0.06). One-year PFS was 9.5 % for gem+placebo, compared with 21.5% for gem+nimo (HR=0.71; p=0.05). Significantly, in pts ≥ 62 years (60% of the population), median OS and PFS were 5.2 mo in the gem+placebo group vs. 8.8 mo in gem+nimo (HR=0.66; p=0.034), and 3.2 in gem+placebo vs. 5.5 mo in gem+nimo group, respectively (HR=0.55; p=0.0096). Nimo was safe and well tolerated, and no grade 3/4 toxicities were observed. Thirteen % of pts experienced grade 1/2 skin toxicity. Conclusions: This randomized study clearly showed that nimo in combination with gem is safe and well tolerated. The 1-year survival rate is significantly improved. Especially pts ≥ 62 years seem to benefit, possibly due to a more aggressive biology in younger pts. Clinical trial information: NCT00561990.

BACKGROUND: Antibiotic-associated diarrhea is an important problem in hospitalized patients. The use of probiotics is gaining interest in the scientific community as a potential measure to prevent this complication. The main objective of the present study was to assess the efficacy and safety of a fermented milk combiningLactobacillus acidophilusandLactobacillus caseithat is widely available in Canada, in the prevention of antibiotic-associated diarrhea.METHODS: In this double-blind, randomized study, hospitalized patients were randomly assigned to receive either a lactobacilli-fermented milk or a placebo on a daily basis.RESULTS: Among 89 randomized patients, antibiotic-associated diarrhea occurred in seven of 44 patients (15.9%) in the lactobacilli group and in 16 of 45 patients (35.6%) in the placebo group (OR 0.34, 95% CI 0.125 to 0.944; P=0.05). The median hospitalization duration was eight days in the lactobacilli group, compared with 10 days in the placebo group (P=0.09). Overall, the lactobacilli-fermented milk was well tolerated.CONCLUSION: The daily administration of a lactobacilli-fermented milk was safe and effective in the prevention of antibiotic-associated diarrhea in hospitalized patients.

TPS4153 Background: Rilotumumab is an investigational, fully human monoclonal antibody to hepatocyte growth factor/scatter factor that inhibits signaling through the MET receptor. In a randomized phase II study in patients with advanced G/GEJ adenocarcinoma, addition of rilotumumab every 3 weeks (Q3W) to ECX showed trends toward improved overall survival (OS) and progression-free survival (PFS) compared with ECX alone. In patients with high tumor MET expression and high rilotumumab exposure, the treatment effect of rilotumumab combined with ECX was significantly enhanced. Methods: In this phase III study, patients (planned N=450) are randomized 1:1 to ECX (intravenous [IV] epirubicin 50 mg/m2 on day 1, IV cisplatin 60 mg/m2 on day 1, and oral capecitabine 625 mg/m2 twice daily on days 1−21) plus double-blind rilotumumab 15 mg/kg or placebo IV Q3W. Randomization is stratified by disease extent (locally advanced vs metastatic) and Eastern Cooperative Oncology Group (ECOG) score (0 vs 1). Key eligibility criteria include previously untreated, pathologically confirmed unresectable locally advanced or metastatic G/GEJ adenocarcinoma; ECOG score 0 or 1; ≥18 years old; MET-positive by centralized immunohistochemistry; HER2-negative; adequate organ function; and ≥6 months since neoadjuvant/adjuvant therapy. The primary endpoint is OS. Key secondary endpoints include PFS, 12-month survival rate, objective response, OS in MET expression tertiles, safety, and pharmacokinetics. An exploratory objective is to assess associations between outcomes and tumor and circulating biomarkers. Enrollment began in November 2012, and the trial continues to accrue. An independent data monitoring committee will conduct planned interim reviews for safety and efficacy. Status: recruiting participants. Sponsored by Amgen Inc. Clinical trial information: NCT01697072.

TPS4148 Background: Tumors often consist of highly hypoxic subregions that are resistant to chemotherapy and radiotherapy. The investigational hypoxia-targeted drug TH-302 is reduced at its nitroimidazole group, and under hypoxic conditions releases the DNA alkylator bromo-isophosphoramide mustard (Br-IPM). A randomized Phase IIb trial of TH-302 in pts with metastatic or locally advanced unresectable pancreatic adenocarcinoma (PDAC) confirmed a significant PFS improvement (p=0.008) in pts treated with TH-302 at 340 mg/m2+ gemcitabine compared with gemcitabine alone (Borad et al, ESMO 2012). Skin and mucosal toxicities, mainly Grade 1/2, and myelosuppression (thrombocytopenia, neutropenia and anemia) were the most common AEs related to TH-302 and did not lead to increases in treatment discontinuation. Grade 3/4 myelosuppression was more frequent in the TH-302 + gemcitabine arm. AEs leading to treatment discontinuation as well as non-hematological serious AEs were balanced across arms. Methods: This is a Phase III, randomized, double-blind, placebo-controlled trial (NCT01746979) of gemcitabine + TH-302 compared with gemcitabine + placebo in pts with locally advanced unresectable or metastatic PDAC. The study is designed to detect a 25% risk reduction of death with 90% power and two-sided alpha of 5%. A total of 660 pts are planned to be randomized 1:1. Key eligibility criteria include histologically or cytologically confirmed disease, no prior chemotherapy or systemic therapy (except as specified in the protocol), ECOG performance status 0 – 1, and bilirubin ≤ 1.5x upper limit of normal. Randomized pts receive TH-302 + gemcitabine or gemcitabine + placebo in 4-week cycles until progressive disease, intolerable toxicity, or pt withdrawal. The primary objective is to evaluate OS. Secondary objectives include PFS, objective response, and disease control; safety and tolerability; pt-reported QoL and pain; CA 19-9 levels and PK of TH-302; exploratory pharmacogenomic markers and potential predictive biomarkers. Enrollment to the study is ongoing. Clinical trial information: NCT01746979.

TPS4143 Background: The tyrosine kinase inhibitor sorafenib is the standard of care for first-line HCC; currently, there is no clear standard of care after disease progression on sorafenib or for patients (pts) with intolerance to sorafenib. Because most HCC is driven by inflammation, there is a strong rationale to evaluate immunotherapy in pts with this type of cancer. The randomized, double-blind, placebo-controlled phase 3 KEYNOTE-240 study (ClinicalTrials.gov, NCT02702401) was designed to compare the efficacy and safety of the anti–PD-1 antibody pembro + BSC vs placebo + BSC in pts with previously treated advanced HCC. Methods: Eligibility criteria include age ≥ 18 years, histologically or cytologically confirmed diagnosis of HCC, documented progression after stopping treatment with sorafenib or intolerance to sorafenib, disease not amenable to a curative treatmentapproach (eg, transplantation, surgery, or ablation), measurable disease confirmed by central imaging vendor review per RECIST v1.1, Child-Pugh liver score A, ECOG performance status 0-1, and predicted life expectancy > 3 months. Pts will be randomly assigned 2:1 to receive pembro 200 mg IV Q3W + BSC or placebo Q3W + BSC for up to 35 cycles (~2 years) or until disease progression, unacceptable toxicity, or investigator decision. Randomization will be stratified by geographic region, presence of macrovascular invasion, and α-fetoprotein level. BSC will be provided by the investigator per local treatment practices. Response will be assessed every 6 weeks per RECIST v1.1 by central imaging vendor review. Adverse events (AEs) will be assessed throughout treatment and for 30 days thereafter (90 days for serious AEs) and graded per NCI CTCAE v4.0. Primary objectives are comparison of progression-free survival per RECIST v1.1 by central imaging vendor review and overall survival between treatment arms. Secondary objectives are comparison of objective response rate, duration of response, disease control rate, and time to progression per RECIST v1.1 by central imaging vendor review; and evaluation of safety and tolerability. Planned enrollment in KEYNOTE-240 is 408 pts across 26 countries. Clinical trial information: NCT02702401.

Abstract Background Approximately 80% of patients with locally advanced pancreatic cancer (LAPC) are treated with chemotherapy, of whom approximately 10% undergo a resection. Cohort studies investigating local tumor ablation with radiofrequency ablation (RFA) have reported a promising overall survival of 26–34 months when given in a multimodal setting. However, randomized controlled trials (RCTs) investigating the effect of RFA in combination with chemotherapy in patients with LAPC are lacking. Methods The “Pancreatic Locally Advanced Unresectable Cancer Ablation” (PELICAN) trial is an international multicenter superiority RCT, initiated by the Dutch Pancreatic Cancer Group (DPCG). All patients with LAPC according to DPCG criteria, who start with FOLFIRINOX or (nab-paclitaxel/)gemcitabine, are screened for eligibility. Restaging is performed after completion of four cycles of FOLFIRINOX or two cycles of (nab-paclitaxel/)gemcitabine (i.e., 2 months of treatment), and the results are assessed within a nationwide online expert panel. Eligible patients with RECIST stable disease or objective response, in whom resection is not feasible, are randomized to RFA followed by chemotherapy or chemotherapy alone. In total, 228 patients will be included in 16 centers in The Netherlands and four other European centers. The primary endpoint is overall survival. Secondary endpoints include progression-free survival, RECIST response, CA 19.9 and CEA response, toxicity, quality of life, pain, costs, and immunomodulatory effects of RFA. Discussion The PELICAN RCT aims to assess whether the combination of chemotherapy and RFA improves the overall survival when compared to chemotherapy alone, in patients with LAPC with no progression of disease following 2 months of systemic treatment.

Platinum Based Chemotherapy

TPS173 Background: Gastric cancer is the fifth most common cancer, and is the third leading cause of cancer deaths worldwide. In patients with locally advanced or metastatic GC, fluoropyrimidine- and platinum-based combination chemotherapy is first-line standard of care. Despite refinement in chemotherapy regimens, outcomes are poor and survival after first-line treatment remains low. A subset of GCs exhibit platinum sensitivity and genomic instability that is characteristic of homologous recombination deficiency (HRD). Poly (ADP-ribose) polymerase proteins 1 and 2 (PARP1/2) are involved in DNA damage repair, and their inhibition is cytotoxic for cells with HRD. Pamiparib is a selective PARP1/2 inhibitor that crosses the blood-brain barrier, has shown potent DNA–PARP trapping, and has demonstrated antitumor activity in preclinical models. In early phase clinical studies (NCT02361723; NCT03333915), pamiparib was generally well tolerated and showed preliminary antitumor activity; 60 mg oral twice daily (BID) was established as the recommended dose. Methods: This ongoing, global, double-blind, placebo-controlled, randomized, multicenter phase III study (NCT03427814) is designed to compare the efficacy, safety, and tolerability of pamiparib vs placebo as maintenance therapy in ~540 patients with advanced GC who have responded to first-line, platinum-based chemotherapy. Patients who are ≤ 8 weeks after their last dose of first-line platinum based chemotherapy will be randomized 1:1 to receive either pamiparib 60 mg BID or placebo in 28-day cycles. Patient randomization will be stratified by genomic loss of heterozygosity status (ie, high vs low), region, and ECOG status. Radiologic assessments will be centrally evaluated per RECIST every 8 weeks after first dose. The primary endpoint is progression-free survival; key secondary endpoints include safety/tolerability, overall survival, objective response rates, time and duration of response, and time to second subsequent treatment. Correlative biomarker analyses in tumor tissues and blood will be performed. Clinical trial information: NCT03427814.

PurposePatients with advanced pancreatic cancer have a poor prognosis and there have been no improvements in survival since the introduction of gemcitabine in 1996. Pancreatic tumors often overexpress human epidermal growth factor receptor type 1 (HER1/EGFR) and this is associated with a worse prognosis. We studied the effects of adding the HER1/EGFR-targeted agent erlotinib to gemcitabine in patients with unresectable, locally advanced, or metastatic pancreatic cancer.Patients and MethodsPatients were randomly assigned 1:1 to receive standard gemcitabine plus erlotinib (100 or 150 mg/d orally) or gemcitabine plus placebo in a double-blind, international phase III trial. The primary end point was overall survival.ResultsA total of 569 patients were randomly assigned. Overall survival based on an intent-to-treat analysis was significantly prolonged on the erlotinib/gemcitabine arm with a hazard ratio (HR) of 0.82 (95% CI, 0.69 to 0.99; P = .038, adjusted for stratification factors; median 6.24 months v 5.91 months). One-year survival was also greater with erlotinib plus gemcitabine (23% v 17%; P = .023). Progression-free survival was significantly longer with erlotinib plus gemcitabine with an estimated HR of 0.77 (95% CI, 0.64 to 0.92; P = .004). Objective response rates were not significantly different between the arms, although more patients on erlotinib had disease stabilization. There was a higher incidence of some adverse events with erlotinib plus gemcitabine, but most were grade 1 or 2.ConclusionTo our knowledge, this randomized phase III trial is the first to demonstrate statistically significantly improved survival in advanced pancreatic cancer by adding any agent to gemcitabine. The recommended dose of erlotinib with gemcitabine for this indication is 100 mg/d.

367 Background: FOLFIRINOX has emerged as a new standard for patients with performance status ECOG 0-1 in metastatic pancreatic cancer and non-randomized studies also support this regimen in locally advanced disease. This regimen is however associated with significant toxicity. The purpose of this study was to assess efficacy and toxicity outside of a clinical trial, including community hospitals. Methods: We conducted a retrospective study of patients with pancreatic adenocarcinoma who received FOLFIRINOX between January 2011 and June 2013 in six institutions in the province of Quebec, Canada. Patients' characteristics, objective response, survival and toxicities were collected. Results: Forty-six patients were included (23 metastatic and 23 locally advanced). Median age was 59 years. Tumor was localized at the head in 65% of patients and 41 % had a biliary stent. Median overall survival was 12,6 months and survival at one year was 61% for metastatic patients. Survival at one year was 95% for locally advanced pancreatic cancer patients and no one with locally advanced tumor became candidate for curative surgery after FOLFIRINOX. Hospitalization rate was 54% with sepsis being the leading cause. There were three treatment-related deaths (7%) and two of them occurred after the first cycle. Neutropenia grade ≥ 3 was observed in 33% of patients and four patients had febrile neutropenia (9 %) with 61% of patients receiving colony stimulating factors (CSFs) for primary prophylaxis. Three patients had cholangitis and diarrhea grade ≥ 3 occurred in 15% of patients. Five patients (11%) experienced transient dysarthria during Irinotecan administration. Conclusions: Survival in our cohort is comparable with data reported by previous studies. However, toxicities were significant and higher than reported. These data highlight the importance of patient selection and support the universal use of CSFs in this population.

155 Background: BRCA-mutated tumors are more susceptible to platinum therapy and PARP inhibitors due to underlying defects in homologous recombination repair of DNA damage. In preclinical models the potent oral PARP1/2 inhibitor veliparib was shown to enhance sensitivity to C and to have single-agent activity in BRCA+ cell lines. Phase 1 trials suggest promising antitumor activity and acceptable toxicity of veliparib plus C/P in triple-negative BC (Puhalla et al. Cancer Res 2012;72:PD09-06) and single-agent activity of veliparib in BRCA+ BC (Somlo et al. J Clin Oncol 2014;32:abstr. 1021). This phase III trial assesses efficacy and toxicity of veliparib plus C/P vs C/P alone in patients with HER2− BRCA-associated locally advanced or metastatic BC (NCT02163694). Methods: Phase III randomized, double-blind, placebo-controlled, multicenter trial. Eligible patients (female or male; ≥ 18 years) have HER2−metastatic/locally advanced unresectable BC with (suspected) deleterious BRCA1/2 germline mutations and received 2 or fewer prior lines of DNA-damaging chemotherapy for metastatic BC. In addition, patients must have received ≤ 1 prior line of platinum therapy (any setting) without progression within 12 months of completing treatment. Patients are randomized 2:1 to C/P with veliparib or C/P with placebo, stratified by estrogen and/or progesterone receptor expression, prior platinum therapy, and central nervous system metastases. Veliparib (120 mg p.o. BID) or placebo will be given on Days −2 to 5, C (AUC 6 mg/mL/min i.v.) on Day 1, and P (80 mg/m2i.v.) on Days 1, 8, and 15 (21-day cycles). Treatment continues until unacceptable toxicity or progressive disease (PD). Patients in the placebo arm who discontinue due to PD are eligible for crossover to veliparib monotherapy. The primary objective is to assess if the addition of veliparib to C/P increases progression-free survival; additional objectives include evaluation of overall survival, clinical benefit rate, objective response rate, quality of life, and safety. Enrollment began in July 2014 with a planned sample size of 270 patients. Clinical trial information: NCT02163694.
