520 Background: BRAF V600 mutations are associated with rare objective responses to the mutated BRAF inhibitor vemurafenib in patients with mCRC. Blockade of BRAFV600 by vemurafenib causes feedback upregulation of EGFR, whose signaling activities can be impeded by cetuximab. In murine models of BRAFV600 mCRC, the combination of irinotecan, cetuximab, and vemurafenib leads to greater anti-tumor activity, as suggested by a prior Phase 1B study. Methods: Patients (pts) with BRAFV600 mutated and extended RAS wild-type mCRC were randomized to irinotecan (180 mg/m2 IV every 14 days) and cetuximab (500 mg/m2 IV every 14 days) with or without vemurafenib (960 mg PO twice daily). Patients had received 1 or 2 prior regimens, with no prior anti-EGFR agents, although prior irinotecan was allowed. Crossover from the control arm to the experimental arm was allowed after documented progression. The primary endpoint was progression-free survival (PFS, investigator assessed), with 90% power to detect a HR of 0.5, with two-sided type 1 error of 5%. Results: 106 patients were enrolled (54 in the experimental arm) from 12/2014 to 4/2016, with ECOG PS ≤ 1. Median age of 62 years, 59% female, and prior irinotecan therapy in 39%. PFS was improved with the addition of vemurafenib (HR = 0.42, 95% confidence interval [CI] of 0.26 to 0.66, P < 0.001) with median PFS of 4.4 (95% CI: 3.6 – 5.7) months vs 2.0 (95% CI: 1.8 – 2.1). Response rate was 16% vs 4% (P = 0.09), with disease control rate of 67% vs 22% (P < 0.001). Grade 3/4 adverse events higher in the experimental arm included neutropenia (28% vs 7%), anemia (13% vs 0%), and nausea (15% vs 0%). There was no increase in skin toxicity or fatigue. No new safety signal was observed. Approximately 50% of patients in the control aim crossed over at the time of progression. Overall survival and efficacy at cross-over data remain immature. Conclusions: The addition of vemurafenib to the combination of cetuximab and irinotecan resulted in a prolongation of progression-free survival and a higher disease control rate, indicating that simultaneous EGFR and BRAF inhibition is effective in BRAFV600 mutated CRC. Clinical trial information: NCT02164916.

3505 Background: Metastatic colorectal cancer (mCRC) patients (pts) with BRAFV600 mutations have poor outcomes with standard of care chemotherapy and rarely respond to the BRAF inhibitor vemurafenib. In preclinical models, blockade of BRAFV600 by vemurafenib (V) causes feedback upregulation of EGFR, whose signaling activities can be impeded by cetuximab (C) with anti-tumor activity augmented by irinotecan (I). Methods: Pts with BRAFV600 mutated and extended RAS wild-type mCRC were randomized to irinotecan (180 mg/m2 IV every 14 days) and cetuximab (500 mg/m2 IV every 14 days) with or without vemurafenib (960 mg PO twice daily). Eligible pts had ECOG PS ≤1, and had received 1 or 2 prior regimens with no prior anti-EGFR agents. Randomization was stratified for prior irinotecan. Crossover from the control arm (IC) to the experimental arm (VIC) was allowed after documented progression. The primary endpoint was progression-free survival (PFS, investigator assessed), with 90% power to detect a HR of 0.5, with two-sided type 1 error of 5%. Results: 106 pts were enrolled (99 eligible, 49 in the experimental arm) from 12/2014 to 4/2016, with median age 62 years, 59% female, and 39% with prior irinotecan therapy. PFS was improved with the addition of vemurafenib (HR 0.42, 95% confidence interval [CI] 0.26 to 0.66, P < 0.001) with median PFS of 4.4 (95% CI 3.6 – 5.7) mos vs 2.0 (95% CI 1.8 – 2.1) months. Response rate was 16% vs 4% (P = 0.08), with disease control rate of 67% vs 22%. In pts with no prior irinotecan, median PFS was 5.7 (95% CI 3.0-6.1) months in the VIC arm vs 1.9 (95% CI 1.7 – 2.1) months in the IC arm. Grade 3/4 adverse events higher in the VIC arm included neutropenia (28% vs 7%), anemia (13% vs 0%), and nausea (15% vs 0%). There was no increase in skin toxicity or fatigue. 23 pts (46%) in the IC arm crossed over at the time of progression, with median PFS from crossover of 6.0 months (95% CI 3.7 – 7.4). Overall survival (OS) data will be mature for ASCO 2017. Conclusions: These results demonstrate the clinical benefits of the VIC triplet (vemurafenib, cetuximab, and irinotecan) in pts with treatment-refractory BRAFV600 mutated mCRC, and support VIC as a potential new treatment option in this molecular subset. Clinical trial information: NCT02164916.

Prognostic And Predictive Markers

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

4136 Background: To investigate the safety and efficacy of capecitabine and oxaliplatin combination therapy (CapOx) in unresectable or metastatic adenocarcinomas of the biliary system. Methods: 65 patients (pts) (27 male, and 38 female) were enrolled (median age, 61 yrs). Major eligibility criteria: histologically proven, measurable disease, age ≤ 75 yrs, ECOG PS 0–2. A total number of 364 cycles (median, 5; range, 1–16) of oxaliplatin (130 mg/m2, d1) plus capecitabine (2 g/m2, d 1–14) were administered 3 weekly for gallbladder carcinoma (GBC) (27 pts), extrahepatic (20 pts), and intrahepatic (18 pts) cholangiocarcinoma (CCC). Response rates were assessed according to WHO criteria. Clinical outcome was determined separately for pts with either GBC/extrahepatic CCC or intrahepatic CCC (mass-forming type). Results: Grade 4 toxicities (WHO): diarrhea in 1 pt (1% of cycles), thrombocytopenia in 1 pt (1%), leukocytopenia in 1 pt (1%), and fever in 2 pts (1%); grade 3 toxicities: nausea/vomiting in 1 pt (1%), diarrhea in 2 pts (1%), thrombocytopenia in 3 pts (2%), and fever in 1 pt (1%). Grade 3/4 peripheral sensory neuropathy (Lévis scale) was found in 13 pts (14% of cycles). Two pts were excluded from study because of oxaliplatin-related allergic reactions. One patient died due to sepsis and another due to cerebral insult during the first treatment cycle. The overall disease control rate in 47 pts with GBC or extrahepatic CCC was 72% (complete response (CR), n = 2 (4%); partial response (PR), n = 11 (23%); stable disease (NC), n = 21 (45%)), whereas progressive disease (PD) was found in 13 pts (28%). In 18 pts with intrahepatic mass-forming CCC, no CR or PR was observed, 5 pts (28%) had SD, and 13 pts (72%) experienced PD. Conclusions: The CapOx protocol is well tolerated and remarkably active for advanced GBC as well as extrahepatic CCC with a disease-control rate of 72%. However, activity appears to be limited in the subset of pts with intrahepatic mass-forming type tumors. Survival data will be presented at the meeting.

4102 Purpose: To compare oxaliplatin (L-OHP) plus raltitrexed (RTX) with L-OHP plus fluorouracil and leucovorin (LV/5FU) for patients (pts) with recurrent and metastatic colorectal cancer(CRC). Methods: Eligible pts had to have histologically proven recurrent or metastatic CRC,not having previously received oxaliplatin as palliative chemotherapy,ECOG PS = 2,age:18∼70,and adequate hematological,renal and hepatic function.After written informed consent,pts were randomized to L-OHP:130 mg/m2 d1 + RTX: 3 mg/m2 d1 (Arm A) or + LV: 200 mg/m2 + 5FU:375 mg/m2 d1–5 (Arm B). Results: Between Jan 2005 and July 2006, 216 pts were enrolled at 15 centers in China.112 pts (mean age: 55.0 (19∼70), M/F: 57/46, PS 0/1/2: 46/53/13) were randomly assigned to A and 102 (mean age: 54.2(22∼70), M/F: 54/46, PS 0/1/2: 44/59/9) to B. 203 pts were eligible for response evaluation (A:103, B:100).The median number of cycles was 4 (1∼6) in A and 3 (1∼6) in B (P=0.1431).The RR was 29.1% (CR:2, PR:28, SD:50 , PD:23) in A and 17.0% (CR:2, PR:15, SD:46 , PD:37) in B (P=0.0437).The disease-control rate was 77.7% in A and 63.0% in B (P=0.0237). After a median follow-up of 10 months (4–16.5),92 pts had had progression of disease (40 in A and 52 in B); 73 deaths had occurred (35 in A and 38 in B), median time to progression was not reached. Following-up is ongoing.The median QoL scores for the two arms were comparable. 214 were included in the safety analyses (A:112, B:102). There was a higher incidence of neutropenia (48.2% verse 29.4%, P=0.005) and transaminase increase (49.1% verse 35.3%, P=0.041) among A. Grade 3 or 4 neutropenia was much common in pts in A than those in B (20.5% verse 4.9% , P=0.001), but was complicated by fever in only 3.6% of cases (4 pts) in A and in 2.9% of cases (3 pts) in B. No pts were dead or infectious due to neutropenia. There were similar rates of grade 3 or 4 transaminase elevation in the two groups. Vomitting and anorexia were much commoner with B. Conclusions: The L-OHP+RTX seems beneficial in recurrent and metastatic CRC, demonstrating better response rate and higher disease control rate with acceptable tolerability, maintenance of QoL and convenient administration schedule.

Abstract Background Malignancies are molecularly complex and become more resistant with each line of therapy. We hypothesized that offering matched, individualized combination therapies to patients with treatment-naïve, advanced cancers would be feasible and efficacious. Patients with newly diagnosed unresectable/metastatic, poor-prognosis cancers were enrolled in a cross-institutional prospective study. Methods A total of 145 patients were included in the study. Genomic profiling (tissue and/or circulating tumor DNA) was performed in all patients, and PD-L1 immunohistochemistry, tumor mutational burden, and microsatellite status assessment were performed in a subset of patients. We evaluated safety and outcomes: disease-control rate (stable disease for ≥ 6 months or partial or complete response), progression-free survival (PFS), and overall survival (OS). Results Seventy-six of 145 patients (52%) were treated, most commonly for non-colorectal gastrointestinal cancers, carcinomas of unknown primary, and hepatobiliary malignancies (53% women; median age, 63 years). The median number of deleterious genomic alterations per patient was 5 (range, 0–15). Fifty-four treated patients (71%) received ≥ 1 molecularly matched therapy, demonstrating the feasibility of administering molecularly matched therapy. The Matching Score, which reflects the percentage of targeted alterations, correlated linearly with progression-free survival (R2 = 0.92; P = 0.01), and high (≥ 60%) Matching Score was an independent predictor of improved disease control rate [OR 3.31 (95% CI 1.01–10.83), P = 0.048], PFS [HR 0.55 (0.28–1.07), P = 0.08], and OS [HR 0.42 (0.21–0.85), P = 0.02]. Serious adverse event rates were similar in the unmatched and matched groups. Conclusions Personalized combination therapies targeting a majority of a patient’s molecular alterations have antitumor activity as first-line treatment. These findings underscore the feasibility and importance of using tailored N-of-1 combination therapies early in the course of lethal malignancies. Trial registration I-PREDICT (NCT02534675) was registered on August 25, 2015.

There is a lack of useful biomarkers for predicting the efficacy of anti–programmed death-1 (PD-1) therapy for advanced gastric and colorectal cancer. To address this issue, in this study we investigated the correlation between inflammatory marker expression and survival in patients with advanced gastric and colorectal cancer. Data for 111 patients with advanced gastric and colorectal cancer treated with anti–PD-1 regimens were retrospectively analyzed. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and clinical characteristics of each patient were selected as the main variables. Overall response rate, disease control rate, and progression-free survival were primary endpoints, and overall survival and immune-related adverse events (irAEs) were secondary endpoints. The chi-squared test and Fisher’s exact test were used to evaluate relationships between categorical variables. Uni- and multivariate Cox regression analyses were performed, and median progression-free survival and overall survival were estimated with the Kaplan–Meier method. The overall response rate and disease control rate of anti–PD-1therapy in advanced gastric and colorectal tumors were 12.61 and 66.66%, respectively. The patients with MLR &lt; 0.31, NLR &lt; 5, and PLR &lt; 135 had a significantly higher disease control rate than those with MLR &gt; 0.31, NLR &gt; 5, and PLR &gt; 135 (P &lt; 0.05). The multivariate analysis revealed that MLR &lt; 0.31, BMI &gt; 18.5, and anti–PD-1 therapy in first-line were associated with prolonged PFS. MLR &lt; 0.31 and BMI &gt; 18.5 were associated with prolonged overall survival. The irAE rate differed significantly between PLR groups, and PLR &lt; 135 was associated with an increased rate of irAEs (P = 0.028). These results indicate that the inflammatory markers NLR, MLR, and PLR have clinical utility for predicting survival or risk of irAEs in patients with advanced gastric cancer and colorectal cancer.

2043 Background: the optimal management of EP with GBM remains controversial. The role of RT with TMZ for EP is unclear, and EP are often treated with RT alone, TMZ alone or palliative approaches. We describe our experience of combining RT with concurrent TMZ for treatment of EP with GBM Methods: medical records of patients ≥65 years old with newly GBM, histologically confirmed at Veneto Institute of Oncology – Padua, and treated with RT plus TMZ, were reviewed. Concomitant TMZ was 75mg/m2/die. The adjuvant treatment consisted of TMZ 150-200mg/m2/die for six cycles. Median progression-free survival(PFS) and overall survival(OS) were estimated with Kaplan-Meier method. Toxicity was scored according to CTCAE 4.0 Results: we analyzed 60 patients(PTS), 34 males and 26 females; the average age was 70 (range 65-82); ECOG PS was 0-1 in 35 PTS and 2 in 25 PTS; complete surgery was performed in 35 PTS, partial surgery in 25 PTS. 40 and 20 PTS received RT within 6 or more weeks (range 7-9) from surgery. MGMT and IDH1 were analyzed in 43 PTS: MGMT methylated in 20 PTS (46%), all PTS had wild-type IDH1. 34 PTS were treated with RT 40Gy in 15 fractions, 26 PTS with RT 60Gy in 30 fractions with no significant difference in ECOG PS, MGMT and type of surgery between the two subgroups. For all PTS, PFS and OS were 9.5 and 12.7 ms, respectively. OS was 13.7 and 12.4 ms (p=0.9) in PTS receiving RT within 6 or more weeks from surgery, respectively. 13% of PTS showed grade 3-4 haematological toxicity, 12% grade 3-4 asthenia, 3% nausea/vomiting. MGMT methylated and complete surgery was associated with a longer survival. PFS was 9 vs 10 months (p=0.4) and OS was 11.7 vs 13.7 ms (p=0.1), for PTS treated with 40Gy and 60Gy, respectively. Regarding toxicity: grade 3-4 haematological toxicity was 9% vs 23%, severe asthenia was 9% vs 15%, nausea/vomiting was 3% vs 4% of PTS receiving RT 40Gy and 60Gy, respectively. Conclusions: RT plus TMZ is effective and safe in EP with GBM and good ECOG PS. PFS and OS was not statistically different between PTS receiving RT 40Gy or 60Gy, although we showed a trend for longer OS with RT 60Gy; in contrast, severe toxicity was higher in PTS with RT 60Gy. OS was similar between PTS receiving RT within 6 or more weeks (7-9ws) from surgery.

352 Background: Pancreatic ductal adenocarcinoma still remains a major cause of cancer related deaths in the western world. The current study was conducted to confirm the activity and feasibility of docetaxel/ oxaliplatin combination in second line treatment of advanced pancreatic ductal adenocarcinoma. Methods: Prospective single arm, non-randomized, multi-center, Simon’s two stage phase II trial using docetaxel (75 mg/m2, 60 min, d 1) and oxaliplatin (80 mg/m2, 120 min, d 2) in 21-day cycles. Duration of the trial was scheduled up two 8 cycles. Primary endpoint was tumor response according to RECIST 1.0. Secondary endpoints were progression free survival, overall survival, safety/toxicity, quality of life and clinical benefit. Results: Data represents the intention to treat analysis of 44 patients included between 2008 and 2012. The majority of patients received a gemcitabine based first-line chemotherapy (95.5%). The primary endpoint of tumor response was achieved in 15.9% (7 partial remissions, no complete remission), with a disease control rate of 48% after the first two treatment cycles. Median progression free survival was 7 weeks (CI 6-15.9 weeks) and overall survival 40 weeks (CI 20.4-56.4 weeks). No unexpected adverse events occured. The recorded AEs were mainly hematologic (neutropenia grade 3/4 63.6%, febrile neutropenia 4.6%), gastrointestinal (29.6% grade 3/4 AEs) and infectious (18.2% grade 3/4 AEs). Conclusions: In this single-arm second line trial for the treatment of advanced PDAC, the combination of docetaxel and oxaliplatin shows promising results comparable with other second line protocols such as OFF (oxaliplatin, 5-FU, leucovorin) or liposomal irinotecan (MM-398) plus 5-FU/leucovorin (NAPOLI 1-trial). Some patients seem to benefit particularly as indicated by long periods of treatment in this setting. Even after 8 cycles of treatment with DocOx, partial response was observed in 2 patients and stable disease in another 6 patients corresponding to a disease control rate of 18%. The toxicity profile was quite tolerable and comparable to other second line studies. Clinical trial information: NCT00690300.

128 Background: Irinotecan is a key drug in second- or further-line chemotherapy for patients with advanced gastric cancer. Continuous administration of trastuzumab beyond first progression is expected to contribute to the benefit of chemotherapy for HER2-positive gastric cancer. We assessed the efficacy and safety of combination chemotherapy with trastuzumab and irinotecan in Japanese patients with advanced HER2-positive chemo-refractory gastric cancer. Methods: Intravenous infusion of irinotecan every 2 weeks at a dose of 150 mg/m2; intravenous infusion of trastuzumab at a dose of 8 mg/kg on day 1 of the first cycle, followed by 6 mg/kg every 3 weeks. Administration of irinotecan and trastuzumab were repeated in independent schedules. The primary endpoint was disease control rate. The secondary endpoints were adverse events, response rate, time-to-treatment failure, progression-free survival, overall survival, and response rate stratified by prior trastuzumab use. This study was conducted by the Osaka Gastrointestinal Cancer Chemotherapy Study Group (OGSG). Results: From October 2012 to Augst 2014, 30 patients were enrolled and one patient withdrew before study treatment. Accordingly, 29 patients were assessable for efficacy and safety. The disease control rate was 65.5% [95% C.I. 45.7 - 82.1%], and the response rate was 20.7% [95% C.I. 8.0 - 39.7%]. The median progression free survival and the median overall survival were 3.7 and 7.5 months, respectively. The major grade 3/4 toxic effects were neutropenia (24%); anemia (24%); leucopenia (21%); anorexia (11%); fatigue (14%); hypoalbuminemia (24%); and hypokalemia (14%). One death (NOS) was considered to be related to the study. Conclusions: The results of combination Trastuzumab with irinotecan showed feasible and promising efficacy against advanced HER2-positive chemo-refractory gastric cancer. These findings indicated that trastuzumab continuation use might be beneficial. Clinical trial information: 000008626.

Abstract   The benefit of systemic treatment in esophageal squamous cell carcinoma (ESCC) which has progressed after chemotherapy is still uncertain. Anlotinib (AL3818) is a novel multi-target TKI, inhibiting tumor angiogenesis and proliferation. A phase II trial (NCT02649361) has demonstrated that anlotinib has a durable antitumor activity with a manageable adverse event profile in refractory metastatic ESCC. This study (NCT03387904) aimed at comparing the effects and safety of Anlotinib Plus Irinotecan versus Irinotecan in patients with ESCC. Methods We conducted a prospective randomized, multicenter, phase II trial to compare the efficacy of Anlotinib Plus Irinotecan with Irinotecan in recurrent ESCC patients who had resistance to platinum or taxane-based chemotherapy. Eligible patients were adults with pathologically confirmed recurrent ESCC, and 82 patients were randomized 1:1 to Irinotecan (65 mg/m2/day 1 and day 8) with or without anlotinib (12 mg qd day 1 to 14) of a 21-day cycle till progression or intolerable. The primary endpoint is the disease control rate (DCR) and progression-free survival (PFS) and the secondary end points are objective response rate (ORR) and overall survival (OS). Results Between 13/1 2019 and 20/1 2020, a total of 43 patients were enrolled and randomly assigned to either the anlotinib plus irinotecan (n = 22) or the irinotecan group (n = 21).The mPFS was longer in trial group than in control group (89 days vs 66 days, HR = 0.447, P = 0.055). The Disease control rate (DCR) was 54.5% in trial group and 38.1% in the control group. The treatment-related adverse events (&gt;10%) were fatigue (59.1%), nausea (50.0%), decreased appetite (36.4%), hoarseness (27.3%), thyroid-stimulating hormone elevation (22.7%), diarrhea (9.1%), and decreased lymphocytes count(9.1%) in trial group. Grade 3 AEs included fatigue (4.5% vs 4.8%), nausea (4.5% vs 0%) and diarrhea (4.5% vs 0%) in two groups. Conclusion Anlotinib plus irinotecan was similarly tolerable but prolonged PFS compared to irinotecan monotherapy as a second-line treatment in patients with recurrent ESCC.
