Purpose This large, multinational study aimed to confirm in a community practice setting the efficacy and safety of cetuximab plus irinotecan in patients with epidermal growth factor–expressing metastatic colorectal cancer (mCRC) who had recently failed an irinotecan-containing regimen. Patients and Methods The primary objective was to determine the progression-free survival (PFS) rate at 12 weeks. The initial cetuximab dose was 400 mg/m2 and was followed weekly by 250 mg/m2; irinotecan (according to prestudy regimen) was given weekly (125 mg/m2 weekly for 4 of 6 weeks), every 2 weeks (180 mg/m2 each), or every 3 weeks (350 mg/m2 each). Results The intention-to-treat/safety population comprised 1,147 treated patients who received irinotecan weekly (n = 93); every 2 weeks (n = 670); every 3 weeks (n = 356); or another dose (n = 28). The PFS rate at 12 weeks was 61%, and the median survival was 9.2 months. Treatment was generally well tolerated. The most common treatment-related grades 3 to 4 adverse events were diarrhea (19%), neutropenia (10%), rash (7%), and asthenia (6%). The rate of grades 3 to 4 infusion-related reactions (IRRs; composite adverse event category) was 1% for patients who received both antihistamine and corticosteroid premedication. Conclusion Tolerability (except IRR incidence), PFS rate, and overall survival rate were in line with previous results. At 1%, the rate of IRRs in patients who received prophylactic premedication with both antihistamine and corticosteroid is lower than previously reported. MABEL clearly confirms in a community practice setting the efficacy and safety of cetuximab plus irinotecan in the treatment of mCRC.

And Function

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.

Chemotherapy Administration

3544 Background: Bevacizumab is a monoclonal antibody that, by inhibiting VEGF, inhibits tumour angiogenesis. It has been proven to improve overall (OS) and progression-free survival (PFS) when administered first-line in combination with the bolus 5-FU-based IFL regimen to patients with metastatic colorectal cancer [Hurwitz et al. NEJM 2004;350:2335–42]. We have conducted a multicentre, open-label trial to further evaluate the efficacy and safety of first-line bevacizumab in combination with regimens combining irinotecan with infusional 5-FU (FOLFIRI). Methods: Eligible patients had: metastatic colorectal cancer; no surgery within 28 days; no prior chemotherapy for metastatic disease; ECOG PS 0/1; adequate organ function; no CNS metastases. Chemotherapy consisted of 6 cycles of irinotecan plus infusional 5-FU and leucovorin, according to the classical FOLFIRI regimen; however, such variations as the simplified FOLFIRI or the weekly regimen were allowed. Bevacizumab 5mg/kg was given on day 1 of chemotherapy, every 2 weeks until disease progression. Safety assessments were made at the time of chemotherapy administration during the first 12 weeks and every 4 weeks thereafter. Tumour assessments were performed every 3 months for the first year and 4-monthly thereafter. The primary objective was PFS; secondary objectives were to evaluate the safety profile of this combination as well as to determine the overall response rate, time to response, duration of response and OS. Results: A total of 209 patients were enrolled at 31 centres in Australia, Canada, Italy, Spain and China between April 2005 and November 2005. 60% of patients were male and median age was 61.9 (range 31–82) years. All patients will be eligible for interim analysis, that will be performed after the last patient enrolled has been followed for a minimum of 12 weeks (6 cycles of chemotherapy), in February 2006. Data on safety and efficacy from this analysis will be presented. Conclusions: This is the largest clinical trial that will report efficacy and safety data for bevacizumab in combination with an irinotecan and infusional 5-FU regimen. [Table: see text]

e15138 Background: Bevacizumab (BEV) has shown clinical activity in metastatic colorectal cancer patients (mCRC)and randomised phase III trials have demonstrated that this agent significantly improves overall and/or progression-free survival when added to first-line irinotecan based chemotherapy (CT) regimens. We evaluated the efficacy and safety of BEV plus FOLFIRI (irinotecan, 5- fluorouracil, and leucovorin) as first line treatment in 27 consecutive metastatic colorectal cancer cases, with the primary end point to calculate the median time to clinical response with this chemotherapeutic schedule. Methods: Between October 2007 and January 2008 we collected the data on 27 patients with mCRC treated with first line chemotherapy with BEV plus FOLFIRI. Elegibility criteria had to be: mCRC; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. The treatment consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI schedule; BEV (5mg/kg) was given on day 1 with CT and then every 2 weeks until disease progression. Safety and response were assessed at the time of first CT and every 4 weeks thereafter. Results: 27 pts were evaluable (male 18; median age 61 years (range 45–77), ECOG PS 0: 52%, PS 1: 48%. The sites of metastases were: liver (15 pts), lung (5 pts), liver and lung (5 pts), peritoneal wall (2 pts).Median follow-up was 18 weeks. Two patients had complete response(CR) and 13 pts partial response (PR), with an overall response rate of 57.7%. Five patients had stable disease and 6 patients showed progressive disease. A clinical benefit was demonstrated in 77 % of pts. We observed a median time to clinical response of 11 weeks, evaluated with tumor markers and with CT/NMR/US examinations. A grade 3 or 4 neutropenia was detected in 39% of pts and grade 2 or 3 hypertension in 9%. We did’nt observe cases of thrombosis, bleeding and gastrointestinal perforation, sometimes related to the use of BEV. Conclusions: In this little experience the efficacy and safety of BEV associated with FOLFIRI schedule, a first line therapy in mCRC,is consistent with results from other previous studies, showing moreover a short time to clinical response with this association.

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.

766 Background: Patients with metastatic colorectal cancer (CRC) usually receive multiple lines of treatment. Using a present day standard 1st line chemotherapy combination a progression free survival in the range of 8-12 months can be obtained. With consecutive treatment lines the median survival has now exceeded the 2-year landmark. In case of disease progression after two or more lines of treatment, the survival is about 4-6 months with best supportive care alone. However, some patients are still able and willing to receive further therapy. In the present retrospective analysis the efficacy of a weekly intravenous high-dose infusion of 5-Fluorouracil and folinic acid in heavily pretreated patients with metastatic CRC beyond the standard chemotherapy lines was evaluated. Methods: The Klinikum Wels-Grieskirchen collects data on all CRC patients since July 2006 in a clinical tumor registry. In this retrospective analysis pretreated CRC patients that were treated with the Ardalan-regimen (500mg/m2 folinic acid as 1 hour infusion followed by 2.600mg/m25-Fluorouracil as 24-hour infusion) have been evaluated. Results: A total of 23 evaluable patients with a median age of 66 years received the Ardalan-regimen as 2nd (4.4%), 3rd (13%), 4th (13%), 5th (52.2%), 6th (4.4%) or 7th (13%) line treatment. The median number of cycles received was 9 (range 2-18) and the Ardalan-regimen was started within 13-56 months (median 26 months) after the diagnosis of metastatic disease. Fourteen (60.9%) and nine (39.1%) out of these patients were women and men, respectively. 60.9% (14 patients) had a tumor located in the colon and 39.1% had rectal cancer. 17.4% of patients had stable disease and 65.2% of patients had progressive disease after 3 months of therapy. In 4 patients response according to RECIST criteria was not evaluable. Median overall survival since the start of the Ardalan-regimen was 6.7 months. Conclusions: Patients with advanced metastatic CRC can be candidates for multiple lines of therapy. In previously heavily pretreated patients, the Ardalan-regimen is able to control the disease in a limited proportion of patients.

115 Background: Recent studies have shown efficacy of chemotherapy (CTX) in combination with different biological agents including regorafenib (REG) in second-line treatment of metastatic colorectal cancer (mCRC). As there is no evidence on the relative efficacy and safety of REG as compared to other biological agents in combination with CTX, we evaluated the same in this network meta-analysis (NMA). Methods: Randomized controlled trials (RCTs) comparing efficacy and safety of biological agents + CTX against CTX alone as second-line treatment of mCRC were retrieved from PubMed, EMBASE and Cochrane databases. Progression free survival (PFS) was the primary outcome, while objective response rate (ORR), overall survival (OS) and safety were secondary outcomes. Outcomes were compared by random/mixed-effects NMA using Bayesian (R software, Gemtc package) and frequentist (R software, netmeta package) approaches. Results: Twelve RCTs comparing 9 different treatment regimens with a total of 6805 patients were included for analysis. Hazard ratios (HR)/ odds ratio (OR)/ relative risk (RR) and 95% confidence intervals (CI) for PFS, ORR and grade> 3 adverse events (AE) of selected comparisons from the results of the NMA are shown in table. Conclusions: REG combined with CTX might be a potential alternative to conventional therapeutic options and could be considered as the best option for treating KRAS and BRAF mutated mCRC patients. Future RCTs are needed to confirm our results. [Table: see text]

Abstract Background: A previous phase I/II C-TASK FORCE study of trifluridine/tipiracil plus bevacizumab for patients with heavily pretreated metastatic colorectal cancer (mCRC) showed promising activity with an acceptable toxicity profile. This retrospective study aimed to investigate the safety and efficacy of trifluridine/tipiracil plus bevacizumab compared with trifluridine/tipiracil monotherapy in patients with heavily pretreated mCRC in clinical settings. Methods: Records of patients with mCRC refractory to standard therapies who initiated trifluridine/tipiracil plus bevacizumab from January 2016 to March 2018 or trifluridine/tipiracil monotherapy from June 2014 to December 2015 were retrospectively reviewed at our institution. Results: Totally, 60 patients received trifluridine/tipiracil plus bevacizumab and 66 received trifluridine/tipiracil monotherapy. All patients had previously received standard chemotherapy. Median progression-free survival (PFS) was 3.7 months [95% confidence interval (CI), 2.3−5.1] in the trifluridine/tipiracil plus bevacizumab group and 2.2 months (95% CI, 1.8−2.6) in the trifluridine/tipiracil monotherapy group [hazards ratio (HR) 0.69; 95% CI 0.48−0.99]. PFS rate at 16 weeks was 46.6% for the trifluridine/tipiracil plus bevacizumab group and 33.9% for the trifluridine/tipiracil monotherapy group. Although a relatively higher incidence of grade ≥3 neutropenia was observed in the trifluridine/tipiracil plus bevacizumab group than that in the other group (50.0% vs. 40.9%, p = 0.371), the incidence of febrile neutropenia was not high (3.3% vs. 7.8%, p = 0.444). Conclusions: In real-world settings, trifluridine/tipiracil plus bevacizumab prolonged PFS and helped achieve higher 16-week PFS rate compared with trifluridine/tipiracil monotherapy in patients with heavily pretreated mCRC with manageable toxicities. Trial registration: Retrospectively registered

Objective We performed this meta-analysis to compare the efficacy and toxicity of regorafenib and TAS-102. Methods Electronic databases were searched to identify studies comparing the efficacy and safety of regorafenib and TAS-102 in patients with chemotherapy-refractory metastatic colorectal cancer using pooled analyses. Results Three clinical trials were included in this analysis. Regarding the reasons for treatment discontinuation, regorafenib was significantly associated with disease progression (odds ratio [OR] = 0.33, 95% confidence interval [CI] = 0.21–0.50) and adverse events (OR = 4.38, 95% CI = 2.69–7.13). However, overall (OR = 0.97, 95% CI = 0.81–1.17) and progression-free survival (OR = 1.01, 95% CI = 0.86–1.18) did not significantly differ between the groups. The most common treatment-related adverse events in the regorafenib group were neutropenia (OR = 0.06, 95% CI = 0.03–0.11), hand–foot syndrome (OR = 50.34, 95% CI = 10.44–242.84), and liver dysfunction (OR = 34.51, 95% CI = 8.30–143.43). Conversely, the incidence of thrombocytopenia did not differ between the two groups. Conclusions Regorafenib and TAS-102 have similar efficacy but different adverse event profiles. Differences in the toxicity profiles of the two drugs will help guide treatment selection.

e14137 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, oxaliplatin and irinotecan. 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.
