ObjectivesCetuximab plus leucovorin, fluorouracil and oxaliplatin (FOLFOX-4) is superior to FOLFOX-4 alone as a first-line treatment for patients with metastatic colorectal cancer with RAS wild-type (RAS wt mCRC), with significantly improved survival benefit by TAILOR, an open-label, randomised, multicentre, phase III trial. Nevertheless, the cost-effectiveness of these two regimens remains uncertain. The following study aims to determine whether cetuximab combined with FOLFOX-4 is a cost-effective regimen for patients with specific RAS wt mCRC in China.DesignA cost-effectiveness model combined decision tree and Markov model was built to simulate pateints with RAS wt mCRC based on health states of dead, progressive and stable. The health outcomes from the TAILOR trial and utilities from published data were used respectively. Costs were calculated with reference to the Chinese societal perspective. The robustness of the results was evaluated by univariate and probabilistic sensitivity analyses.ParticipantsThe included patients were newly diagnosed Chinese patients with fully RAS wt mCRC.InterventionsFirst-line treatment with either cetuximab plus FOLFOX-4 or FOLFOX-4.Main outcome measuresThe primary outcomes are costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs).ResultsBaseline analysis disclosed that the QALYs was increased by 0.383 caused by additional cetuximab, while an increase of US$62 947 was observed in relation to FOLFOX-4 chemotherapy. The ICER was US$164 044 per QALY, which exceeded the willingness-to-pay threshold of US$28 106 per QALY.ConclusionsDespite the survival benefit, cetuximab combined with FOLFOX-4 is not a cost-effective treatment for the first-line regime of patients with RAS wt mCRC in China.Trial registration numberTAILOR trial (NCT01228734); Post-results.

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.

491 Background: Infusional fluorouracil/leucovorin plus irinotecan-based regimen (FOLFIRI) with bevacizumab has been widely used as first-line treatment for patients with metastatic colorectal cancer (mCRC). We prospectively analyzed the influence of uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) genotyping for irinotecan dose escalation in mCRC patients treated with combination of FOLFIRI and bevacizumab as the first-line setting. Methods: A total of 65 mCRC patients undergoing first-line treatment with FOLFIRI combined with bevacizumab were analyzed. Genotypes were performed by analyzing the sequence of TATA box of UGT1A1 of genomic DNA from the patients. Genotype and clinical parameters were compared by univariate analysis. The irinotecan dose is escalating form 180 mg/m2 to 260 mg/m2 in UGT1A1 6/6 or 6/7, and from 120 mg/m2 to 210 mg/m2 in UGT1A17/7. Results: The response rate was observed in 44 of 60 UGT1A1 6/6 or 6/7 (73.3%) in comparison to 1 of 5 UGT1A1 7/7 (20%) patients (p=0.013). The grade III-IV adverse events (AE) was observed in 4 of 60 UGT1A1 6/6 or 6/7 (6.7%) in comparison to 3 of 5 UGT1A1 7/7 (60%) patients (p<0.001), but it was not different between age of ≥ 70 and < 70 (p=0.559). Fifteen of 60 (20%) patients with UGT1A1 6/6 or 6/7 could be performed with liver or lung metastaectomy in comparison to none of 5 patients with UGT1A1 7/7. In addition, the disease control rate was significantly higher in irinotecan dose of ≥ 210 mg/m2 than irinotecan dose of < 210 mg/m2(p=0.015). Conclusions: UGT1A1 promoter polymorphism was found to be predictive of toxicity and efficacy in mCRC patients with first-line treatment of FOLFIRI combined with bevacizumab. The higher dose of irinotecan (≥ 210 mg/m2) may achieve a better disease control rate but do not increase the incidence of GR III-IV AE in mCRC patients of age ≥ 70 years.

PurposeIn the phase III study AVF2107g, bevacizumab (BV) demonstrated a survival benefit when added to irinotecan, fluorouracil, and leucovorin (IFL) in first-line metastatic colorectal cancer (mCRC). In a parallel phase III study, Intergroup N9741, oxaliplatin plus fluorouracil and leucovorin (FOLFOX) also demonstrated a survival benefit compared with IFL. As these two superior therapies have differing mechanisms of action, we explored whether the improved survival associated with the superior therapy was dependent on tumor response.Patients and MethodsFor these retrospective, exploratory analyses, patients were defined as responders or nonresponders by whether complete or partial response was achieved with first-line therapy.ResultsCompared with IFL alone, BV plus IFL and FOLFOX each demonstrated statistically significant improvements in progression-free survival (PFS) and overall survival (OS) regardless of objective tumor response. BV-treated nonresponders had a hazard ratio (HR) of 0.63 (P = .0001) for PFS and 0.76 (P = .0188) for OS compared with IFL-treated nonresponders. FOLFOX-treated nonresponders had an HR of 0.75 (P = .0029) for PFS and 0.74 (P = .0030) for OS compared with IFL-treated nonresponders.ConclusionIn both AVF2107g and N9741, objective response did not predict the magnitude of PFS or OS benefit from the superior therapy; nonresponders, despite a poorer prognosis than responders, achieved extended PFS and OS from BV plus IFL or FOLFOX compared with IFL. On the basis of these data, tumor response in metastatic colorectal cancer is not a necessary factor for a therapy to provide benefit to an individual patient.

625 Background: The polymorphisms of genes encoding drug-metabolizing enzymes can play a crucial role in the increased susceptibility of patients to chemotherapy. This study is a prospective, multicenter, randomized clinical trial to compare the clinical outcomes and adverse events in metastatic colorectal cancer (mCRC) patients treated with bevacizumab plus 5-fluorouracil/leucovorin/irinotecan (FOLFIRI) with or without UGT1A1genotyping and irinotecan dose escalation as the first-line setting (NCT02256800). Methods: The enrolled patients were randomly assigned to one of two groups on the basis of receiving UGT1A1 genotyping or not. The study group receives a biweekly FOLFIRI plus bevacizumab, with irinotecan dose escalation based on UGT1A1 genotyping; whereas the control group receives the conventional biweekly FOLFIRI plus bevacizumab without UGT1A1 genotyping. The primary endpoint was the overall response rate (ORR), and the second endpoint was progression-free survival (PFS), overall survival (OS) and toxicities between the two groups. Results: BetweenAugust 2013 and May 2016, eighty-eight mCRC patients were enrolled, including 45 patients in the study group and 43 patients in the control group. With a median follow up time of 12.5 months (range, 5-30), the ORR was 71.4% vs. 44.2% ( P = 0.011). The PFS was 14.04 ± 1.44 vs. 9.08 ± 0.58 months in study group and control group ( P = 0.195), OS was 19.12 ± 1.24 vs. 14.16 ± 1.04 months ( P = 0.098), and ≥ Gr. III anemia was 2.2% vs. 23.3% ( P= 0.002) in study group and control group, respectively. However, there were no significant differences in ≥ Gr. III leukopenia or diarrhea even though the 1.36 fold relative dose intensity (RDI) in the study group. Conclusions: In the current study, patients with mCRC undergoing UGT1A1 genotyping may receive escalated doses of irinotecan for a potentially more favorable clinical response and outcome, in addition to acceptable toxicities. Such a personalized medicine based on genotyping may be feasible for potentially clinical practice. Clinical trial information: NCT02256800.

115 Background: Antiangiogenic agents, in particular monoclonal antibodies (mAbs) against VEGF, a major driver of tumor angiogenesis, are widely used in cancer therapy including metastatic colorectal cancer (mCRC). However, some patients do not profit from antiangiogenic treatments (AT), other patients benefit initially, but subsequently develop resistance not only to chemotherapy but also to AT. So far, no biomarkers are available to predict resistance to AT. Having an accurate assessment of imminent resistance to an AT may e.g. enable to respond by treating the patient with a more broadly acting antiangiogenic agent and thereby further delay resistance to the treatment and at the same time avoid employing a not anymore efficacious treatment. We hypothesized that repeated analysis of multiple cytokines related to angiogenesis together with machine learning approaches may enable an accurate prediction of anti-VEGF resistance during first-line treatment of mCRC patients with FOLFOX plus bevacizumab. The PERMAD trial aimed at establishing a CAF marker combination that enables the prediction of treatment resistance of patients with mCRC receiving Bevacizumab plus mFOLFOX6 in a palliative first-line setting about three months prior to radiological progress using an omics approach and bioinformatics. Methods: A phase I/II biomarker trial was conducted, including 15 centers in Germany and Austria. All mCRC patients included were treatment naïve and received FOLFOX plus Bevacizumab treatment. 102 different, preselected CAFs were prospectively collected and centrally analyzed in plasma samples (n = 647) obtained prior to treatment and biweekly until radiological progress determined by CT scan every 2 months. The values of CAFs affected in a similar fashion by both chemotherapy and disease progress were excluded. Using the remaining CAFs we employed a random forest predictor to define a combination of 5 CAF (CAF marker combination) whose change in values/pattern correlated with subsequent progress 3 months prior to radiological progress according to RECIST 1.1. Results: Using the samples described above and a random forest predictor we established a CAF marker combination comprising 5 CAF whose specific change in value/pattern over time indicated treatment resistance 3 months prior to radiological progress. The model allowed to differentiate timepoints without progress from timepoints predicting progress 100 days before radiological progress with an accuracy of 83%, a sensitivity of 76% and specificity of 88%. Conclusions: Using advanced bioinformatics, we identified a CAF marker combination that points out treatment resistance to FOLFOX plus Bevacizumab in patients with mCRC 3 months prior to radiological progress. Clinical trial information: NCT02331927.

795 Background: Epidermal growth factor receptor (EGFR) antibodies, cetuximab (C) and panitumumab (P) have shown improvement in clinical outcomes for distinct molecular profiles in metastatic colorectal cancer (mCRC). In the first line setting, EGFR targeting of left-sided tumors has shown favorable clinical outcomes when compared to right-sided tumors. Here we examined the efficacy of EGFR therapy in the treatment refractory setting as well as the impact of tumor bulk on clinical outcomes. Methods: A retrospective cohort of 72 patients (pts) with KRAS wild-type mCRC were identified who received either C or P in the late-line setting. Tumor measurements were performed per RECIST v1.1. Disease bulk was defined as single lesion with longest diameter or lymph node with short axis > 3.5 cm. Right colon primary was defined proximal to splenic flexure. Results: In pts with treatment refractory right-sided disease the response rate (RR) was 16.7%, progression free survival (PFS) was 3.7 months (mo), and overall survival (OS) was 14.0 mo. This was compared to left sided disease with RR of 26.0%, PFS 6.2 mo (p < 0.05), and OS 15.0 mo. In the non-bulky cohort the RR was 32.4%, PFS 7.9 mo, and OS 18.4 mo. In the bulky cohort the RR was 5.3% (p < 0.01), PFS 4.0 mo (p < 0.02), and OS 6.6 mo. In the right-sided non-bulky cohort there was a RR of 33% v. 0% in the right-sided bulky cohort. In the left-sided non-bulky cohort there was a RR of 32.3% v. 7.7% in the bulky cohort (p < 0.05). Conclusions: These data indicate that tumor bulk can predict clinical outcomes for anti-EGFR targeting. In the late line setting, pts with left-sided cancers overall trended towards improvements in clinical outcomes, consistent with prior understanding in first line setting. Despite a limited cohort size, response was observed in pts with non-bulky right-sided disease. There was limited-to-no benefit of anti-EGFR targeting with right-sided bulky disease. Left-sided non-bulky patient received the greatest benefit from anti-EGFR targeting. Future prospective studies of targeted therapeutics should incorporate tumor bulk and sidedness when assessing clinical outcomes and tumor biology.
