Aims: BEAWARE investigated the pattern of first-line bevacizumab early interruption in the Italian real-world setting of metastatic colorectal cancer. Methods: A total of 386 patients were followed for 15 months after first-line chemotherapy + bevacizumab start. The rate of bevacizumab interruption for progression or adverse drug reactions (ADRs) constituted the primary endpoint. Results: A total of 78.2% of patients interrupted bevacizumab: 56.6% for progression, 7.3% for ADRs, and 36.1% for other reasons. Median treatment duration was 6.7, 2.5, and 4.6 months, respectively. Median progression-free survival was 10.3 months; however, 35.8% of patients were not progressed and were thus censored at the data cutoff of 15 months, while 21.8% were still receiving bevacizumab. Patients discontinuing for progression/ADRs more frequently had metastases in >1 site ( p = .0001), and a shorter median progression-free survival (6.9 vs 13.9 months, p < .0001). Conclusions: In Italy, first-line bevacizumab is interrupted mainly for progression, only 7.3% due to adverse events, and about one third of cases for other reasons. In clinical practice, the attitude to treat until progression as per guidelines might be implemented. ClinicalTrials.gov Identifier: NCT01609075

Abstract Background FOLFOXIRI plus bevacizumab is used as a first-line therapy for patients with unresectable or metastatic colorectal cancer. However, there are no clear recommendations for second-line therapy after FOLFOXIRI plus bevacizumab combination. Here, we describe our planning for the EFFORT study to investigate whether FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for mCRC. Methods EFFORT is an open-label, multicenter, single arm phase II study to evaluate whether a FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for mCRC. Patients with unresectable or metastatic colorectal cancer who received FOLFOXIRI plus bevacizumab as a first-line therapy will receive aflibercept and FOLFIRI (aflibercept 4 mg/kg, irinotecan 150 mg/m2 IV over 90 min, with levofolinate 200 mg/m2 IV over 2 h, followed by fluorouracil 400 mg/m2 bolus and fluorouracil 2400 mg/m2 continuous infusion over 46 h) every 2 weeks on day 1 of each cycle. The primary endpoint is progression-free survival (PFS). To achieve 80% power to show a significant response benefit with a one-sided alpha level of 0.10, assuming a threshold progression-free survival of 3 months and an expected value of at least 5.4 months, we estimated that 32 patients are necessary. Secondary endpoints include overall survival, overall response rate, safety, and exploratory biomarker analysis for differentiating anti-VEGF drug in 2nd-line chemotherapy for unresectable or metastatic colorectal cancer. Discussion This is the first study to investigate whether FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for unresectable or metastatic colorectal cancer. Switching to a different type of anti-VEGF drug in second-line therapy after FOLFOXIRI plus bevacizumab appears to be an attractive treatment strategy when considering survival benefit. It is expected that this phase II study will prove the efficacy of this strategy and that a biomarker for drug selection will be discovered.

Purpose The aim was to investigate whether germline polymorphisms within candidate genes known or suspected to be involved in fluorouracil (FU), oxaliplatin, and irinotecan pathways were associated with toxicity and clinical outcome in patients with metastatic colorectal cancer (mCRC). Patients and Methods Blood samples from 349 patients included in the Fédération Francophone de Cancérologie Digestive 2000-05 randomized trial, which compared FU plus leucovorin (LV5FU2) followed by FU, leucovorin, and oxaliplatin (FOLFOX) followed by FU, leucovorin, and irinotecan (FOLFIRI; sequential arm) with FOLFOX followed by FOLFIRI (combination arm) in terms of progression-free survival (PFS) and overall survival, were collected. Twenty polymorphisms within the DPD, TS, MTHFR, ERCC1, ERCC2, GSTP1, GSTM1, GSTT1, and UGT1A1 genes were genotyped. Results The ERCC2-K751QC allele was independently associated with an increased risk of FOLFOX-induced grade 3 or 4 hematologic toxicity (P = .01). In the sequential arm, TS-5′UTR3RG and GSTT1 alleles were independently associated with response to LV5FU2 (P = .009) and FOLFOX (P = .01), respectively. The effect of oxaliplatin on tumor response increased with the number of MTHFR-1298C alleles (test for trend, P = .008). The PFS benefit from first-line FOLFOX was restricted to patients with 2R/2R (hazard ratio [HR] = 0.39; 95% CI, 0.23 to 0.68) or 2R/3R (HR = 0.59; 95% CI, 0.42 to 0.82) TS-5′UTR genotypes, respectively. Conversely, patients with the TS-5′UTR 3R/3R genotype did not seem to benefit from the adjunction of oxaliplatin (HR = 0.96; 95% CI, 0.66 to 1.40; trend between the three HRs, P = .006). Conclusion A pharmacogenetic approach may be a useful strategy for personalizing and optimizing chemotherapy in mCRC patients and deserves confirmation in additional prospective studies.

588 Background: Bevacizumab (BV) is a recombinant, humanized monoclonal antibody against vascular endothelial growth factor. Used in combination with chemotherapy, BV has been shown to improve survival in both first- and second-line treatment for metastatic colorectal cancer (mCRC). However, it was reported that addition of BV to FOLFOX conferred only little survival benefit (Saltz et al. JCO2008). The aim of this study was to assess the efficacy of addition of BV to FOLFOX in first-line treatment for patients with mCRC. Methods: Bevacizumab was approved for mCRC in July 2007 in Japan. This study was conducted at a single institution and comprised 217 consecutive patients receiving first-line treatment for mCRC between 2005 and 2009. The primary objective was to compare survival benefit in patients treated with FOLFOX4 (FF) between 2005 and 2007 with that in patients receiving FOLFOX4+BV 5 mg/kg (FF+BV) between 2007 and 2009. Results: Total number of patients in the FF and FF+BV groups was 132 and 85, respectively. Characteristics of patients were as follows (FF vs. FF+B): median age, 62 yrs (range 28-76 yrs) vs. 60 yrs (range16-74 yrs); ECOG PS0, 98.8% vs. 81.8%; and median follow-up time, 20.8 months vs. 24.4 months. Median progression-free survival (PFS) in the FF and FF+BV groups was 10 months (95% CI, 8.7-11.3) and 17 months (95% CI, 10.2-14.1), while median overall survival (OS) was 21 months (95% CI, 17.9-24.1) and not reached, respectively. Response rate was 46% (95% CI, 37- 54) in FF, and 62% (95% CI, 51-73) in FF+BV. Addition of BV to FOLFOX4 significantly improved PFS (p=0.002) and OS (p<0.001). Conclusions: The additive effect of BV for first-line FOLFOX was reconfirmed. These data indicate potential survival benefits from the addition of BV to FOLFOX in first-line treatment of mCRC. In addition, PFS may be a sensitive indicator of outcome prior to post-treatment. No significant financial relationships to disclose.

The Relationship

First-line treatment of metastatic colorectal cancer with combinations of cetuximab and irinotecan-based or oxaliplatin-based chemotherapy has shown promising efficacy. The clinical response to such treatment is generally assessed by tumor measurement through imaging. This study was performed to evaluate the correlation between serial changes in imaging results and carcinoembryonic antigen (CEA) levels. In 64 patients with metastatic colorectal cancer receiving cetuximab plus FOLFIRI or FOLFOX-4 chemotherapy we retrospectively analyzed the relationship between changes in serum CEA and changes in imaging results throughout the treatment course. Response in terms of serum CEA change was defined as a ≥50% drop in CEA level for more than 4 weeks. The sensitivity and specificity of serum CEA changes after targeted chemotherapy in relation to imaging results were 80.5% (33/41) and 73.9% (17/23), respectively, with a diagnostic accuracy of 78.1% (50/64). The progression-free survival time of responders assessed by serum CEA change was significantly longer than that of nonresponders (p=0.0091). Our results highlight the importance of serum CEA monitoring in assessing the response to targeted chemotherapy and in predicting the prognosis of patients with metastatic colorectal cancer.

This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of bevacizumab in combination with fluoropyrimidine-based chemotherapy for the first-line treatment of metastatic colorectal cancer based on the manufacturer’s submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. Evidence was available in the form of one phase III, multicentre, multinational, randomised, open-label study (NO16966 trial). This two-arm study was originally designed to demonstrate the non-inferiority of oral capecitabine plus oxaliplatin (XELOX) compared with 5-fluorouracil plus folinic acid plus oxaliplatin (FOLFOX)-4 in adult patients with histologically confirmed metastatic colorectal cancer who had not previously been treated. Following randomisation of 634 patients, the open-label study was amended to include a 2 × 2 factorial randomised (partially blinded for bevacizumab) phase III trial with the coprimary objective of demonstrating superiority of bevacizumab in combination with chemotherapy compared with chemotherapy alone. Measured outcomes included overall survival, progression-free survival, response rate, adverse effects of treatment and health-related quality of life. The manufacturer’s primary pooled analysis of superiority (using the intention-to-treat population) showed that after a median follow-up of 28 months, the addition of bevacizumab to chemotherapy significantly improved progression-free survival and overall survival compared with chemotherapy alone in adult patients with histologically confirmed metastatic colorectal cancer who were not previously treated [median progression-free survival 9.4 vs 7.7 months (absolute difference 1.7 months); hazard ratio (HR) 0.79, 97.5% confidence interval (CI) 0.72 to 0.87; p = 0.0001; median overall survival 21.2 vs 18.9 months (absolute difference 2.3 months); HR 0.83, 97.5% CI 0.74 to 0.93; p = 0.0019]. The NO16966 trial was of reasonable methodological quality and demonstrated a significant improvement in both progression-free survival and overall survival when bevacizumab was added to XELOX or FOLFOX. However, the size of the actual treatment effect of bevacizumab is uncertain. The ERG believed that the modelling structure employed was appropriate, but highlighted several key issues and areas of uncertainty. At the time of writing, NICE was yet to issue the guidance for this appraisal.

578 Background: BV is widely used for treatment of metastatic colorectal cancer (mCRC) patients. Although BV was often administrated to mCRC patients in combination with oxaliplatin, optimal schedule remains unclear. Many mCRC patients cannot continue to use oxalipatin because of cumulative neurotoxity, which decreases patient's QOL and motivation.We postulated that modification of oxaliplatin schedule would improve TTF in intermittent oxaliplatin usage. Therefore, we planned to use BV with original OPTIMOX1 adiministration schedule; modified oxaliplatin dose (85 mg/m3). Methods: Patients were enrolled with the criteria excluding neuropathy, PS ≥ 1, or no previous usage of oxaliplatin and BV, and then were received modified FOLFOX6 regimen (L-OHP 85 mg/m2, l-LV 200 mg/m2, 5-FU 400 mg/m2 bolus, 5-FU 2,400 mg/m2 46h continuous infusion) plus BV (5 mg/kg) q2wks x 6 cycles, followed sLV5FU2 (omit L-OHP) plus BV x 12 cycles regimen. After that, oxaliplatin reintroduction was done and mFOLFOX6 plus BV regimen was continued until PD. The evaluation of antitumor effect was done according to RECIST Criteria. Results: 40 patients accrued this trial. Median age was 65 years old. PS0: 89.5%, male: 75%, female: 25%, colon: 65.8%, rectal: 31.6%,colon + rectal: 2.6%. During initial 6 cycles of chemotherapy, 90% patients could continue chemotherapy. Response rate was 50%, and clinical benefit (including SD) was 92.1%. During Intial 6 cycles, G3 neuropathy occurred 2.6%, and G2 were 5%. Most frequent toxicity (≥G3) was neutropenia (30.8%) and anorexia (5.3%). One patient could complete the scheduled regimen. This patient continued mFOLFOX6+BV for 12 cycles after reintroduction keeping with PS 0, and was received FOLFIRI+BV regimen as second-line chemotherapy. Further information are under examination. Conclusions: This administration schedule was well tolerated and could continue chemotherapy longer than usual method. sLV5FU2+BV regimen was not affected reintroduction rate and progression free survival. BV with mOPTIMOX1 regimen can be expected to become a good treatment options for mCRC patients. No significant financial relationships to disclose.

e14166 Background: Bevacizumab (Bev) induced hypertension (HTN) may be a predictive biomarker of anti-tumor activity in patients with metastatic colorectal cancer (mCRC) . We retrospectively assessed if significant rise in blood pressure (SRBP) [ ≥ 20 mmHg ] or any grade of HTN within first 10 weeks of treatment with bev is associated with improved clinical outcomes. Methods: Retrospective review of all mCRC patients, on or off clinical trial, treated with first line chemotherapy plus Bev (5 mg/kg Q2W or 7.5 mg/kg Q3W) at our institution from 2005-2010 was conducted .BP was measured before each treatment and graded according to CTCAE version 3.0.The median follow-up time of eligible patients was 19.6 months. Results: Of 50 patients eligible for the analysis, 20 patients (40%) developed significant rise in BP or HTN (SRH) whereas 30 patients had no change (NRH). There were no statistical differences between the two groups with respect to age, gender, ECOG status, number of sites of metastases, pre-existing HTN (55% SRH,37% NRH ; P=0.251) and first line chemotherapy regimen. Chemotherapy regimens used in SRH and NRH groups were 5-Fluoropyrimidine based (25% vs 23.3%), irinotecan based (40% vs. 36.7%) and oxaliplatin based (35% vs 30%). Four patients (20%) in the SRH group developed SRBP and other patients in this group developed G1-G3 HTN according to CTCAE v3.0.SRH group had improved median progression free survival (15.8 vs 6.2 months ; p<0.001) and overall survival (25.9 vs. 16 months; p=0.005). Overall response rate was higher in the SRH group (75% vs 26.7%; p=0.001). Conclusions: SRH developing within 10 weeks of commencing first line chemotherapy with bev correlates with improved outcomes in mCRC. These data need confirmation in prospective studies.

3593 Background: The FIRIS study (Muro K et al. Lancet Oncol 2010;11:853–860) previously demonstrated the non-inferiority of Irinotecan plus S-1(IRIS) to FOLFIRI for metastatic colorectal cancer(mCRC), with progression-free survival (PFS) as the primary endpoint. We previously reported that IRIS plus bevacizumab(IRIS/bev) is very effective as first-line treatment (Komatsu Y et al. ESMO 2010). We now report the updated results of this study. Methods: Eligible patients had to have mCRC with a confirmed diagnosis of adenocarcinoma, an age of >20 years, ECOG performance status (PS) of 0-1, and no history of prior chemotherapy. S-1 40-60 mg twice daily p.o. was given on days 1-14 and irinotecan 100 mg/m2 and bevacizumab 5 mg/kg i.v. were given on days 1 and 15 of a 28-day cycle. The primary endpoint was safety. The secondary endpoints included overall response (OR), progression-free survival (PFS), and overall survival (OS). Results: The target number of 53 patients was enrolled as of March 2009. The results are reported for 52 patients with evaluable lesions. The clinical characteristics of the patients were as follows. The median age was 63.5 years (range, 48 to 82). The male:female ratio was 3:2. The performance status on the Eastern Cooperative Oncology Group scale was 0. In January 2012, on safety analysis, the incidence of grade 3 or 4 neutropenia was 27%. The incidences of other grade 3 or 4 adverse reactions were as follows: diarrhea, 17%; anorexia, 4%; stomatitis, 2%; hypertension, 21%; and gastrointestinal perforation, 0%. The overall response rate was 63.5%. Three patients had complete response. Thirty patients had partial response, 16 had stable disease, none had progressive disease, and 3 were not evaluable. Median progression-free survival was 17.0 months and median survival time was 39.6 months. Conclusions: IRIS/Bev is a remarkably active and generally well-tolerated first-line treatment for patients with mCRC. Randomized control trial comparing this regimen with oxaliplatin containing regimen(XELOX or mFOLFOX6 plus bevacizumab) is being planned.
