Purpose In metastatic colorectal cancer, phase III studies have demonstrated the superiority of fluorouracil (FU) with leucovorin (LV) in combination with irinotecan or oxaliplatin over FU + LV alone. This phase III study investigated two sequences: folinic acid, FU, and irinotecan (FOLFIRI) followed by folinic acid, FU, and oxaliplatin (FOLFOX6; arm A), and FOLFOX6 followed by FOLFIRI (arm B). Patients and Methods Previously untreated patients with assessable disease were randomly assigned to receive a 2-hour infusion of l-LV 200 mg/m2 or dl-LV 400 mg/m2 followed by a FU bolus 400 mg/m2 and 46-hour infusion 2,400 to 3,000 mg/m2 every 46 hours every 2 weeks, either with irinotecan 180 mg/m2 or with oxaliplatin 100 mg/m2 as a 2-hour infusion on day 1. At progression, irinotecan was replaced by oxaliplatin (arm A), or oxaliplatin by irinotecan (arm B). Results Median survival was 21.5 months in 109 patients allocated to FOLFIRI then FOLFOX6 versus 20.6 months in 111 patients allocated to FOLFOX6 then FOLFIRI (P = .99). Median second progression-free survival (PFS) was 14.2 months in arm A versus 10.9 in arm B (P = .64). In first-line therapy, FOLFIRI achieved 56% response rate (RR) and 8.5 months median PFS, versus FOLFOX6 which achieved 54% RR and 8.0 months median PFS (P = .26). Second-line FOLFIRI achieved 4% RR and 2.5 months median PFS, versus FOLFOX6 which achieved 15% RR and 4.2 months PFS. In first-line therapy, National Cancer Institute Common Toxicity Criteria grade 3/4 mucositis, nausea/vomiting, and grade 2 alopecia were more frequent with FOLFIRI, and grade 3/4 neutropenia and neurosensory toxicity were more frequent with FOLFOX6. Conclusion Both sequences achieved a prolonged survival and similar efficacy. The toxicity profiles were different.

PurposeTo evaluate whether capecitabine plus oxaliplatin (XELOX) is noninferior to fluorouracil. folinic acid, and oxaliplatin (FOLFOX-4) as first-line therapy in metastatic colorectal cancer (MCRC).Patients and MethodsThe initial design of this trial was a randomized, two-arm, noninferiority, phase III comparison of XELOX versus FOLFOX-4. After patient accrual had begun, the trial design was amended in 2003 after bevacizumab phase III data became available. The resulting 2 × 2 factorial design randomly assigned patients to XELOX versus FOLFOX-4, and then to also receive either bevacizumab or placebo. We report here the results of the analysis of the XELOX versus FOLFOX-4 arms. The analysis of bevacizumab versus placebo with oxaliplatin-based chemotherapy is reported separately. The prespecified primary end point for the noninferiority analysis was progression-free survival.ResultsThe intent-to-treat population comprised 634 patients from the original two-arm portion of the study, plus an additional 1,400 patients after the start of the amended 2 × 2 design, for a total of 2,034 patients. The median PFS was 8.0 months in the pooled XELOX-containing arms versus 8.5 months in the FOLFOX-4–containing arms (hazard ratio [HR], 1.04; 97.5% CI, 0.93 to 1.16). The median overall survival was 19.8 months with XELOX versus 19.6 months with FOLFOX-4 (HR, 0.99; 97.5% CI, 0.88 to 1.12). FOLFOX-4 was associated with more grade 3/4 neutropenia/granulocytopenia and febrile neutropenia than XELOX, and XELOX with more grade 3 diarrhea and grade 3 hand-foot syndrome than FOLFOX-4.ConclusionXELOX is noninferior to FOLFOX-4 as a first-line treatment for MCRC, and may be considered as a routine treatment option for appropriate patients.

PURPOSE: To compare the efficacy and tolerability of eniluracil (EU)/fluorouracil (5-FU) with that of 5-FU/leucovorin (LV) as first-line therapy for patients with metastatic/advanced colorectal cancer. PATIENTS AND METHODS: This multicenter, randomized, open-label, phase III study (FUMA3008) conducted in the United States and Canada compared the safety and efficacy of EU/5-FU (11.5 mg/m2/1.15 mg/m2 twice daily for 28 days every 35 days) with that of intravenous 5-FU/LV (425 mg/m2/20 mg/m2 once daily for 5 days every 28 days) in patients with previously untreated metastatic colorectal cancer. Overall survival (OS) was the primary end point. RESULTS: A total of 981 patients were randomized and 964 patients received treatment (485 EU/5FU, 479 5FU/LV). Survival for EU/5-FU was not statistically equivalent (but not statistically inferior) to that for 5-FU/LV (hazard ratio, 0.880; 95% confidence interval [CI], 0.75 to 1.03). Median duration of survival was 13.3 months in the EU/5-FU group and 14.5 months in the 5-FU/LV group. Median duration of progression-free survival for EU/5-FU was statistically inferior to that of the control group (20.0 weeks [95% CI, 19.1 to 20.9 weeks] v 22.7 weeks [95% CI, 18.3 to 24.6 weeks]; P = .01). Both treatments were well tolerated. Diarrhea was the most common nonhematologic toxicity in both groups; treatment-related grade 3 or 4 diarrhea occurred in 19% of patients treated with EU/5-FU and 16% of patients receiving 5-FU/LV (P = .354). Grade 3 or 4 granulocytopenia occurred in 5% of EU/5-FU patients and 47% of 5-FU/LV patients. CONCLUSION: Safety profiles of both treatments were acceptable. Although antitumor activity was observed, EU/5-FU did not meet the protocol-specified statistical criteria for equivalence to 5-FU/LV in terms of OS.

PURPOSE: In a previous study of treatment for advanced colorectal cancer, the LV5FU2 regimen, comprising leucovorin (LV) plus bolus and infusional fluorouracil (5FU) every 2 weeks, was superior to the standard North Central Cancer Treatment Group/Mayo Clinic 5-day bolus 5FU/LV regimen. This phase III study investigated the effect of combining oxaliplatin with LV5FU2, with progression-free survival as the primary end point. PATIENTS AND METHODS: Four hundred twenty previously untreated patients with measurable disease were randomized to receive a 2-hour infusion of LV (200 mg/m2/d) followed by a 5FU bolus (400 mg/m2/d) and 22-hour infusion (600 mg/m2/d) for 2 consecutive days every 2 weeks, either alone or together with oxaliplatin 85 mg/m2 as a 2-hour infusion on day 1. RESULTS: Patients allocated to oxaliplatin plus LV5FU2 had significantly longer progression-free survival (median, 9.0 v 6.2 months; P = .0003) and better response rate (50.7% v 22.3%; P = .0001) when compared with the control arm. The improvement in overall survival did not reach significance (median, 16.2 v 14.7 months; P = .12). LV5FU2 plus oxaliplatin gave higher frequencies of National Cancer Institute common toxicity criteria grade 3/4 neutropenia (41.7% v 5.3% of patients), grade 3/4 diarrhea (11.9% v 5.3%), and grade 3 neurosensory toxicity (18.2% v 0%), but this did not result in impairment of quality of life (QoL). Survival without disease progression or deterioration in global health status was longer in patients allocated to oxaliplatin treatment (P = .004). CONCLUSION: The LV5FU2-oxaliplatin combination seems beneficial as first-line therapy in advanced colorectal cancer, demonstrating a prolonged progression-free survival with acceptable tolerability and maintenance of QoL.

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.

457 Background: the DREAM study compares a maintenance therapy with bevacizumab (bev) alone or with the erlotinib after a bev-based induction therapy with FOLFOX, or biweekly XELOX or FOLFIRI. Efficacy of the induction treatment is reported here. Methods: Patients (pts) with previously untreated metastatic colorectal cancer received one of the following regimen (investigator’s choice): mFOLFOX7-bev, biweekly mXELOX-bev or FOLFIRI-bev. Oxaliplatin was administered no more than 6 cycles. In the 1st cohort, pts received 3 months (m) of FOLFOX-bev or mXELOX-bev before randomization. In the 2nd cohort, pts received 3m of FOLFOX-bev or mXELOX-bev then 3 m of fluoropyrimidine-bev, or 6 m of FOLFIRI-bev before randomization. Pts with disease control were then randomized between bev alone or with erlotinib until progression. Results: FOLFOX-bev was administered in 424 pts, mXELOX-bev in 203 pts and FOLFIRI-bev in 67 pts. Pts characteristics for the whole population are: median age 63 yrs (26-80), male/female 59.8%/40.2%, synchronous mets/metachronous 82.6%/17.4%, PS 0/1/2 58%/39%/3%, LDH>UNL 53%, platelets >400000/mm3 27%. Patients received a median nb of 6 cycles of oxaliplatin for FOLFOX-bev and mXELOX-bev, and a median nb of 12 cycles of irinotecan with FOLFIRI-bev. Response rates are respectively 48%, 50% and 63%. Median PFS are respectively 8.61m, 8.97m and 9m. Severe toxicity profiles (grade 3-4) appear to be different according to the schedule : more neutropenia and diarrhea with FOLFIRI-bev, HFS and diarrhea with mXELOX-bev and neuropathy with FOLFOX-bev. Conclusions: Modified biweekly XELOX-bev provides similar efficacy results with FOLFOX-bev, and FOLFIRI-bev as induction therapy in first-line. Clinical trial information: NCT00265824.

TPS789 Background: Treatment of metastatic colorectal cancer (mCRC) has improved due to the introduction of more active chemotherapies (CT) and novel targeted agents that have significantly increased response rate (RR), progression free survival (PFS) and overall survival (OS). Recently, CORRECT and CONCUR trials have demonstrated both activity and efficacy of regorafenib, a small multi-kinase inhibitor, as monotherapy in pretreated mCRC. The wide range of action of regorafenib makes it an ideal candidate for monotherapy in earlier disease treatment lines in which different pathways could be involved in the acquisition of resistance. To improve long term efficacy of first line therapy several therapeutic approaches of maintenance treatment have been explored in mCRC. Methods: RAVELLO is an academic randomized, double-blind, placebo-controlled, multi-center, phase III study designed to evaluate efficacy and safety of regorafenib as maintenance treatment after first line therapy. Eligible patients: pathologically confirmed mCRC RAS wild type (KRAS and NRAS genes) treated with a first line fluoropyrimidine-based CT in combination with an anti-EGFR (epidermal growth factor receptor) monoclonal antibody for a minimum of 4 to a maximum of 8 months, with a stratification by response to the first line treatment (complete response/partial response or stable disease). 480 patients will be enrolled and randomly assigned in a 1:1 ratio to receive 160 mg regorafenib or placebo per os, every day for 3 weeks of every 4 weeks cycle, until disease progression or unacceptable toxicity. Primary endpoint is PFS. With a two-tailed alpha error of 0.05, the study will have 90% power to detect a 3-month prolongation of median PFS from randomization (corresponding to a hazard ratio of progression of 0.67 with 6-month median PFS expected in the control arm). Secondary endopoint are OS, safety, and biomarker correlative studies. Currently, one patient has been enrolled and is on treatment. EudraCT number: 2013-005428-41. Clinical trial information: 2013-005428-41.

Purpose5-Fluorouracil/leucovorin, oxaliplatin, irinotecan (FOLFOXIRI) plus bevacizumab is more effective than doublets plus bevacizumab as first-line therapy for metastatic colorectal cancer, but is not widely used because of concerns about toxicity and lack of predictive biomarkers. This study was designed to explore the role of circulating tumour cell (CTC) count as a biomarker to select patients for therapy with FOLFOXIRI-bevacizumab.Patients and methodsVISNÚ-1 was a multicentre, open-label, randomised, phase III study in patients with previously untreated, unresectable, metastatic colorectal carcinoma and ≥3 CTC/7.5 mL blood. Patients received bevacizumab 5 mg/kg plus FOLFOXIRI (irinotecan 165 mg/m2, oxaliplatin 85 mg/m2, leucovorin 400 mg/m2 and 5-fluorouracil 3200 mg/m2) or FOLFOX (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil 400 mg/m2 then 2400 mg/m2) by intravenous administration every 2 weeks. The primary outcome was progression-free survival (PFS).ResultsThe intention-to-treat population comprised 349 patients (FOLFOXIRI-bevacizumab, n=172; FOLFOX-bevacizumab, n=177). Median PFS was 12.4 months (95% CI 11.2 to 14.0) with FOLFOXIRI bevacizumab and 9.3 months (95% CI 8.5 to 10.7) with FOLFOX-bevacizumab (stratified HR, 0.64; 95% CI 0.49 to 0.82; p=0.0006). Grade≥3 adverse events were more common with FOLFOXIRI-bevacizumab 85.3% vs 75.1% with FOLFOX-bevacizumab (p=0.0178). Treatment-related deaths occurred in 8 (4.7%) and 6 (3.4%) patients, respectively.ConclusionsFirst-line FOLFOXIRI-bevacizumab significantly improved PFS compared with FOLFOX-bevacizumab in patients with metastatic colorectal cancer and ≥3 CTCs at baseline, which indicate a poor prognosis. CTC count may be a useful non-invasive biomarker to assist with the selection of patients for intensive first-line therapy.
