488 Background: We conducted a phase II trial of gemcitabine with S-1 to evaluate the activity and toxicity of such a combination in heavily pre-treated patients (pts) with metastatic colorectal cancer (mCRC) who have progressed after treatment with 5-fluorouracil (5-FU), oxaliplatin and irinotecan. Methods: 34 pts were enrolled, with the following characteristics: 17 (50%) females, median age 57 years (28-72), 28 (82%) ECOG PS 0-1. S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was four (range 1-9). ORR was 14.7% (95% confidence interval [CI] 2.8-26.6) and disease control rate was 58.8% (95% CI 42.2-75.3) with five partial responses and fifteen stable diseases. Median duration of disease control was 5.1 months (95% CI 3.3-7.0). Median progression-free survival was 3.2 months (95% CI 2.3-4.1) and median overall survival was 11.8 months (95% CI 7.0-16.5). Grade 3-4 toxicities were neutropenia (12%), anemia (12%), thrombocytopenia (3%) and diarrhea (3%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was well tolerated and efficacious for heavily pre-treated mCRC pts, and could be an alternative for pts with good PS but no further treatment options.

3595 Background: We conducted a phase II trial of gemcitabine with S-1 to evaluate the activity and toxicity of such a combination in heavily pre-treated patients (pts) with metastatic colorectal cancer (mCRC) who have progressed after treatment with fluoropyrimidines-, oxaliplatin- and irinotecan-containing regimens. Methods: 36 pts were enrolled, with the following characteristics: 19 females (53%), median age 57 (28-72), 30 EOGO PS 0-1 (83%). S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was 5 (range 1-9), ORR was 16.7% (95% confidence interval [CI] 4.5-28.9%) and disease control rate was 61.1% (95% CI 45.2-77.0%) with 6 partial responses and 16 stable diseases. Median duration of disease control was 5.8 months (95% CI 4.1-7.5 months). Median progression-free survival was 3.7 months (95% CI 2.2-5.2 months) and median overall survival was 10.0 months (95% CI 7.4-12.7 months). Grade 3-4 toxicities were rare (neutropenia 12%, anemia 11%, leucopenia 6%, thrombocytopenia 3% and diarrhea 3%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was a convenient, well tolerated and efficacious for heavily pre-treated pts with mCRC. This regimen warrants further evaluation in pts with good PS but no further treatment options.

Methods: Between Dec 2009 and Nov 2011, 23 pts were enrolled, with the following characteristics: 12 males and 11 females, median age 57 years (28-72). S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was four (range 1-9). OR was 8.7% (95% confidence interval [CI] 0-20.2) and disease control rate was 56.5% (95% CI 36.4-76.9) with two partial responses and eleven stable diseases. Median duration of disease control was 8.5 months (95% CI 3.8-13.2). Median progression-free survival was 3.2 months (95% CI 1.9-4.5) and median overall survival was 11.8 months (95% CI 4.0-19.5). Grade 3-4 toxicities were neutropenia (8%) and thrombocytopenia (4%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was well tolerated and efficacious for refractory mCRC pts.

841 Background: The aim of this multicenter, single-arm phase II trial was to investigate the efficacy and safety of S-1 plus bevacizumab (BEV) as a salvage treatment for patients with metastatic colorectal cancer (mCRC) refractory to standard chemotherapies. Methods: Patients who had unresectable mCRC with mutant-type KRAS; were refractory to fluoropyrimidine, irinotecan, oxaliplatin; and had previous treatment with BEV were enrolled and received S-1 plus BEV therapy (bevacizumab 7.5 mg/kg on day 1 and S-1 40-60 mg bid on day 1-14, every 3 weeks). The primary endpoint was progression-free survival (PFS), and secondary end points included overall survival (OS), tumor response, and safety. Results: A total of 27 patients were enrolled. After a median follow-up period of 12.3 months, the events of disease progression and death occurred in 26 patients (96%) and 20patients (74%), respectively. The median number of treatment cycles was 3 (range, 1-17 cycles). Median PFS was 2.3 months (95% confidence interval [CI], 2.2-2.4 months), and the median OS was 7.7 months (95% CI, 4.3-10.1 months). The overall response and disease control rates were 0% and 33%, respectively. The median tumor shrinkage rate (DpR) was -15% (range, -59 to 15%). The frequencies of hematological and non-hematological adverse events above grade three were 25% and 8%, respectively. Conclusions: S-1 plus BEV therapy could be feasible salvage line treatment for Japanese patients with mCRC refractory to standard chemotherapies. Clinical trial information: UMIN000006476.

PURPOSE: To study tolerability and efficacy of an intensified chronomodulated schedule of fluorouracil (5-FU) and l-folinic acid (l-FA) as first-line treatment of metastatic colorectal cancer, 5-FU was given near individually determined dose-limiting toxicity in a multicenter phase II trial. PATIENTS AND METHODS: One hundred patients (68 men and 32 women, median age 62 years, World Health Organization performance status ≤ 2) with previously untreated and inoperable metastases received chronomodulated daily infusion of 5-FU/l-FA (from 10:00 pm to 10:00 am with peak at 4:00 am). 5-FU dose was escalated from 900 to 1,100 mg/m2/d with fixed dose of l-FA at 150 mg/m2/d for 4 days every 14 days. RESULTS: 5-FU dose escalation was achieved in 66% of the patients. Grade 3 to 4 toxicities mainly consisted of nausea or vomiting (14% of patients and 1.5% of courses), hand-foot syndrome (38% of patients and 8% of courses), mucositis (26% of patients and 4% of courses), and diarrhea (21% of patients and 2.3% of courses). Objective response rate (ORR) was 41% (95% confidence interval, 31.5% to 50.5%). Twenty patients underwent metastases surgery; among these, 12 had a complete resection. Median progression-free survival was 7 months. Median survival was 17 months; 28% of the patients were alive at 2 years and 18.6% at 3 years. CONCLUSION: The ORR achieved with intensified chronomodulated delivery of 5-FU/l-FA was nearly twice as high as that earlier obtained by our cooperative group using less intensive 5-FU/FA chronotherapy.

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.

3595 Background: Ispinesib(SB-715992) is a polycyclic, nitrogen-containing heterocycle that inhibits the mitotic kinesin spindle protein (KSP). KSP is essential for mitotic spindle assembly and function during mitosis, and is a rational target of anti-cancer therapy. This phase II study used two different dosing schedules; the primary objective was to determine the response rate (RR) and the secondary objectives were to determine time to tumor progression (TTP), progression free survival (PFS), overall survival (OS) and toxicity. Methods: Patients (pts) were randomized to receive (Arm A) ispinesib 7 mg/m2 every week for 3 weeks, every 28 days or (Arm B) 18 mg/m2 every 21 days. Response was assessed every 6 weeks. Chemotherapy was administered until disease progression or intolerance. Results: A total of 64 pts were accrued. The median number of cycles was 2 for both arms. Five pts had stable disease and 48 had progressive disease. PFS was 49 days in Arm A (44 to 51) and 37 days in Arm B (35 to 42 days). The most common grade 3/4 toxicities in arms A and B respectively included neutropenia (3 and 20), nausea and vomiting (3 and 1), neurologic (1 and 2). Of these, only 1 pt had febrile neutropenia and 1 pt had peripheral sensory neuropathy. The toxicity data is not available on 2 patients. Eleven pts are not evaluable for response yet. Conclusions: Ispinesib did not demonstrate significant activity in heavily pretreated patients with advanced/metastatic colorectal cancer at the dose and schedule employed in this trial. Correlative studies are in progress. Supported by NO1 CM17101 [Table: see text] No significant financial relationships to disclose.

560 Background: Everolimus (E) is an oral inhibitor of mTOR. Tivozanib (T) is a highly potent, selective, oral inhibitor of VEGF receptors-1, -2, and -3. Preclinical data suggest antitumor activity for this combination in colorectal cancer. We therefore performed a multicenter Phase Ib trial of E + T in patients (pts) with any refractory gastrointestinal (GI) malignancy, followed by a Phase II trial of E + T in pts with refractory, metastatic colorectal cancer (mCRC). Methods: Eligibility criteria: histologically confirmed, measurable disease; ECOG PS≤2; blood pressure ≤150/100; no venous thromboembolism within prior 6 months. Pts with mCRC must have received prior fluoropyrimidine, irinotecan, oxaliplatin, bevacizumab and anti-EGFR antibody (if KRAS wt). E was administered once daily continuously. T was administered once daily for 3 out of every 4 weeks. The Phase Ib study in pts with any GI malignancy followed a standard 3+3 design with 3 dose levels: (1) E 5 mg/d + T 1 mg/d; (2) E 10 mg/d + T 1 mg/d; (3) E 10 mg/d + T 1.5 mg/d. The Phase II study in pts with mCRC was a non-randomized, one-stage design with a primary endpoint of progression-free survival. Results: Between 02/10-12/10, 12 pts were enrolled to the Phase Ib study. Median age, 60 (39-81) years; male, 50%; ECOG PS 0/1/2, 42/58/0%; tumor types: esophagus 1, colorectal 11 pts. Dose limiting toxicities of grade 3 fatigue and grade 3 fatigue/ dehydration occurred in 2/6 pts on dose level 3. Grade 3/4 treatment-related adverse events in ≥10% of pts were dehydration, fatigue, headache, hyperglycemia, hypertension, and hypophosphatemia. The phase II study proceeded at the maximally tolerated dose (MTD) of E 10 mg/d and T 1 mg/d. Between 02/11-06/11, 40 pts with mCRC were enrolled to the phase II study. All but 1 pt received prior bevacizumab. Median age, 56 (35-81) years; male, 48%; ECOG PS 0/1/2, 45/53/2%. Treatment is ongoing. Conclusions: Among pts with refractory GI malignancies, the combination of Everolimus + Tivozanib was well-tolerated with MTD of E 10 mg/d and T 1 mg/d. A phase II trial has completed enrollment using these doses of E + T in pts with refractory mCRC; safety and efficacy data will be available for presentation.

260 Background: Recent placebo-controlled phase III trials of the mTOR inhibitor everolimus and the VEGF/ PDGF receptor inhibitor sunitinib in PNET noted improved progression-free survival (PFS). However, objective response rates (RR) with these agents are <10%. Preclinical studies suggest enhanced anti-tumor effects with combined mTOR and VEGF targeted therapy. Methods: We conducted a phase II trial of the mTOR inhibitor TEM (25 mg IV q week) and the VEGF-A monoclonal antibody BEV (10 mg/kg IV q 2 weeks) in patients (pts) with well or moderately differentiated PNET and progressive disease by RECIST within 7 months of study entry. Co-primary endpoints were RR and 6-month PFS. Planned enrollment is 50 patients, with interim analysis after the first 25 evaluable pts. Pts had no prior mTOR or VEGF targeted agents, ECOG PS 0-1, and adequate hematologic and organ function. Continued octreotide was allowed, but not required. Prior interferon, embolization, and ≤ 2 chemotherapy regimens were allowed. Results: Confirmed PR was documented in 11 of the first 25 (44%) evaluable patients. 20 of 25 (80%) patients were progression-free at 6 months. Both endpoints exceeded pre-defined criteria to continue enrollment. For 35 evaluable patients, the most common grade 3-4 adverse events attributed to therapy were leukopenia (12%), hypertension (12%), hyperglycemia (12%), mucositis (9%), and fatigue (9%). Conclusions: The combination of TEM/BEV has substantial activity in a multi-center phase II trial with RR of 44%, well in excess of single targeted agents in PNET. 6-month PFS was a notable 80% in a population of patients with RECIST criteria progression within 7 months of study entry. Accrual is ongoing. Supported by NCI N01 Contracts: 662205, 62203, 62208, 62209, 62206, 62204, 62207, 62201.

635 Background: Sorafenib and irinotecan (NEXIRI regimen) showed promising activity with a disease control rate (DCR) of 65% in heavily pretreated mutated (mt) KRAS metastatic colorectal cancer (mCRC) patients in a phase I/II trial (Samalin et al. 2014).This multicentre randomized phase II trial aimed to determine the 2-month progression-free survival rate (2-PFS) of NEXIRI versus irinotecan or sorafenib monotherapy in mtRAS mCRC patients after failure of all approved active drugs at the time of the study. Methods: Patients PS ≤ 1 with progressive measurable and non-resectable mtKRAS (then RAS) mCRC pre-treated with irinotecan, oxaliplatin, fluoropyrimidines and bevacizumab (none regorafenib), were randomized in 3 arms: NEXIRI (irinotecan IV 120 (C1), 150 (C2) and 180mg/m² (C3) if diarrhea grade < 1 in a biweekly regimen combined with a fixed dose of sorafenib, 400mg twice daily) versus irinotecan alone (180mg/m²) versus sorafenib alone until progression or toxicity, with cross over to NEXIRI at progression for the monotherapy arms. The primary endpoint was the 2-PFS (RECIST v1.1). Pharmacokinetic, pharmacogenetics and pathologic translational studies were undertaken. Results: We included 173 patients (median age 62 [31-82]; PS 0/1: 38/61%) between 2012/09 and 2014/07 in 17 French centres. Main results are shown below (median follow-up 17.5 months). Conclusions: We confirmed the NEXIRI regimen efficacy in a randomized study for refractory mtRAS mCRC patients. These results justify comparing this combination to regorafenib or TAS 102 monotherapies in this population. Ancillary studies are ongoing to identify biomarkers. Clinical trial information: NCT01715441. [Table: see text]
