365 Background: The role of anti-EGFR therapy in first-line treatment of metastatic colorectal cancer (mCRC) is not established. In the present study pts were randomized to FLOX or FLOX + cetuximab until progression or FLOX intermittently + cetuximab continuously. Methods: Treatment arm A: Nordic FLOX (q2w): oxaliplatin 85 mg/m2day 1, 5-FU bolus 500 mg/m2 and FA 60 mg/m2 day 1-2; B: FLOX + cetuximab, initial dose 400 mg/m2, then 250 mg/m2/week; C: FLOX for 16 weeks + cetuximab continuously, with FLOX added at progression. Primary endpoint was progression-free survival (PFS). Results: Between May 05-Oct 07, 571 pts were randomized, 566 pts evaluable in intention to treat (ITT) analyses. Median age was 61 (24-74). ECOG status: 0=67%, 1=29%, 2=4%. KRAS and BRAF mutation (mut) analyses were obtained in 498 (87%) and 457 pts (81%), respectively. 40% of tumors had KRAS mut, 12% had BRAF mut. Cetuximab combined with Nordic FLOX did not significantly improve RR, PFS or OS compared to FLOX. KRAS mutation was not predictive for cetuximab effect. OS was similar for patients treated with FLOX intermittently and cetuximab continuously as for patients treated until progression. BRAF mutation was a strong negative prognostic factor (median OS 7.6 vs. 20.4 mo). Conclusions: Cetuximab did not add significant benefit to the Nordic FLOX regimen in first-line treatment of mCRC, irrespective of KRAS-mut. [Table: see text] [Table: see text]

First Line Treatment

PurposeThis phase III study compared the safety and efficacy of the following three different irinotecan-containing regimens in the first-line treatment of metastatic colorectal cancer: irinotecan plus infusional fluorouracil (FU)/leucovorin (LV) (FOLFIRI), irinotecan plus bolus FU/LV (mIFL), and irinotecan plus oral capecitabine (CapeIRI).Patients and MethodsA total of 430 previously untreated metastatic colorectal cancer patients were randomly assigned to receive FOLFIRI (n = 144), mIFL (n = 141), or CapeIRI (n = 145). Patients were concurrently randomly assigned to a double-blind treatment with celecoxib or placebo. After a protocol amendment, an additional 117 patients were randomly assigned to either FOLFIRI plus bevacizumab (FOLFIRI+Bev; n = 57) or mILF plus bevacizumab (mIFL+Bev; n = 60), whereas the CapeIRI arm was discontinued. The primary study end point was progression-free survival (PFS), with secondary end points of overall survival (OS), response rate, and toxicity.ResultsMedian PFS was 7.6 months for FOLFIRI, 5.9 months for mIFL (P = .004 for the comparison with FOLFIRI), and 5.8 months for CapeIRI (P = .015). Median OS was 23.1 months for FOLFIRI, 17.6 months for mIFL (P = .09), and 18.9 months for CapeIRI (P = .27). CapeIRI was associated with higher rates of severe vomiting, diarrhea, and dehydration. After the amendment to add bevacizumab, the median survival time has not yet been reached for FOLFIRI+Bev and was 19.2 months for mIFL+Bev (P = .007). FOLFIRI+Bev was associated with a higher rate of ≥ grade 3 hypertension than mIFL+Bev.ConclusionFOLFIRI and FOLFIRI+Bev offered superior activity to their comparators and were comparably safe. An infusional schedule of FU should be the preferred irinotecan-based regimen in first-line metastatic colorectal cancer.

PurposeThis phase II study investigated the efficacy and safety of cetuximab combined with standard oxaliplatin-based chemotherapy (infusional fluorouracil, leucovorin, and oxaliplatin [FOLFOX-4]) in the first-line treatment of epidermal growth factor receptor–expressing metastatic colorectal cancer (mCRC).Patients and MethodsThe activity of cetuximab plus oxaliplatin was investigated in colon cancer cell lines and xenograft models. In the clinical study, patients with mCRC received on day 1 of a 14 day cycle, cetuximab (initial dose 400 mg/m2during week 1, then 250 mg/m2weekly) followed by FOLFOX-4 (oxaliplatin 85 mg/m2on day 1; leucovorin 200 mg/m2on days 1 and 2, followed by fluorouracil 400 mg/m2bolus then 600 mg/m2intravenous infusion during 22 hours on days 1 and 2).ResultsThe preclinical studies confirmed the supra-additive activity of cetuximab to oxaliplatin. In the clinical study, 43 patients were included, with a median age of 65 years (range, 43 to 78 years). Response rates (RRs) were 79% (unconfirmed) and 72% (confirmed), with 95% disease control. Median progression-free survival (mPFS) and median duration of response were 12.3 and 10.8 months, respectively. Ten patients (23%) underwent resection with curative intent of previously unresectable metastases. After a median follow-up of 30.5 months, median overall survival (mOS) was 30.0 months. Cetuximab did not increase the characteristic toxicity of FOLFOX-4 and was generally well tolerated.ConclusionCetuximab in combination with FOLFOX-4 is a highly active first-line treatment for mCRC, showing encouraging RR, mPFS, and mOS values. The treatment resulted in a high resectability rate, which could potentially result in an improved cure rate. This combination is under phase III development.

PURPOSE: To study how adding oxaliplatin (l-OHP) to chronomodulated fluorouracil (5-FU)–leucovorin (LV) affected the objective response rate, as first-line treatment of metastatic colorectal cancer. PATIENTS AND METHODS: Two hundred patients from 15 institutions in four countries were randomly assigned to receive a 5-day course of chronomodulated 5-FU and LV (700 and 300 mg/m2/d, respectively; peak delivery rate at 0400 hours) with or without l-OHP on the first day of each course (125 mg/m2, as a 6-hour infusion). Each course was repeated every 21 days. Response was assessed by extramural review of computed tomography scans. RESULTS: Grade 3 to 4 toxicity from 5-FU–LV occurred in ≤ 5% of the patients (≤ 1% of the courses). Grade 3 to 4 diarrhea occurred in 43% of the patients given l-OHP (10% of the courses), and less than 2% of the patients had severe hematotoxicity. Thirteen percent of the patients had moderate functional impairment from peripheral sensory neuropathy. Sixteen percent of the patients receiving 5-FU–LV had an objective response (95% confidence interval [CI], 9% to 24%), compared with 53% of those receiving additional l-OHP (95% CI, 42% to 63%) (P < .001). The median progression-free survival time was 6.1 months with 5-FU–LV (range, 4.1 to 7.4 months) and 8.7 months (7.4 to 9.2 months) with l-OHP and 5-FU–LV (P = .048). Median survival times were 19.9 and 19.4 months, respectively. CONCLUSION: By chronomodulating 5-FU–LV, we were able to add l-OHP without compromising dose-intensities. l-OHP significantly improved the antitumor efficacy of this regimen.

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.
