Abstract Background: In the first-line treatment of metastatic colorectal cancer (mCRC) patients with CAPOX plus bevacizumab, the optimal duration of maintenance treatment without oxaliplatin to avoid discontinuation of therapy due to peripheral sensory neuropathy (PSN) remains unknown. The aim of this phase II study was to evaluate the efficacy and safety of combination therapy with five-cycle CAPOX (capecitabine plus oxaliplatin) plus bevacizumab, followed by five-cycle maintenance therapy with capecitabine plus bevacizumab and reintroduction of CAPOX plus bevacizumab for five cycles, with a preplanned oxaliplatin intermittent strategy in mCRC.Methods: Patients with untreated mCRC were administered CAPOX [oxaliplatin 130 mg/m2 and capecitabine (2000 mg/m2 daily) as intermittent treatment for 14 days, followed by a 7-day treatment-free interval, every 3 weeks] + bevacizumab (7.5 mg/kg) every 3 weeks for five cycles, maintenance treatment without oxaliplatin for five cycles, and CAPOX + bevacizumab reintroduction for five cycles or upon tumor progression. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were the time to treatment failure (TTF), overall survival, response rate (RR), and safety.Results: Forty-seven patients who fulfilled the inclusion criteria were enrolled in the evaluation of efficacy and safety. The relative dose intensity and the cumulative dose of oxaliplatin during the overall treatment period were 649.1 mg/m2 and 1132.5 mg, respectively. Median PFS was 14.1 months (95% confidence interval [CI], 8.6–19.5), and median TTF was 12.3 months (95% CI, 10.3–14.3). The objective RRs were 51.1% (24/47) during induction therapy, 58.3% (21/36) during maintenance therapy, and 63.6% (14/22) during reintroduction therapy. The frequency of patients with neutropenia, diarrhea, PSN, venous thromboembolism, or grade ≥ 3 allergic reactions was 2.1%.Conclusion: CAPOX plus bevacizumab therapy with a preplanned intermittent oxaliplatin strategy consisting of brief five-cycle induction therapy, five-cycle maintenance therapy with capecitabine plus bevacizumab, and five-cycle reintroduction therapy consisting of CAPOX plus bevacizumab is safe and effective for mCRC patients.Trial registration: This trial was registered with the University Hospital Medical Information Network on 7 June 2011 (UMIN ID: 000005732).

761 Background: In metastatic colorectal cancer (mCRC), the benefit of the molecular targeted drugs added to chemotherapy has been reported and a combination therapy of capecitabine (CAP) and oxaliplatin (CapeOX) plus bevacizumab (BEV) is an established first-line therapy for mCRC. However, the management of the cumlateve neurotoxicity of oxaliplatin still remains. We evaluated the efficacy and safety of CapeOX plus BEV with oxaliplatin stop and go strategy. Methods: Two prospective clinical trials of previously untreated unresectable mCRC were analyzed. Fifty four patients were treated with CapeOX plus BEV with oxaliplatin stop and go strategy (CCOG-0902). They were treated 4 cycles of CapeOX plus BV therapy followed by maintenance therapy of 8 cycles of Capecitabine plus BV and oxaliplatin reintroduction was scheduled after maintenance therapy or upon tumor progression. On the other group, forty seven patients were treated with mFOLFOX6 plus BEV (CCOG-0801). Progression free survival (PFS), overall survival (OS), response rate (RR), disease control rate (DCR), relative dose intensity (RDI), and frequency of peripheral sensory neuropathy (PSN) were evaluated. Results: Patient characteristics were balanced between the two groups. The median RDI of oxaliplatin in CCOG-0902 group was significantly higher, 92% than in CCOG-0801 group, 80%. RR and DCR were 61.5% and 96.3% respectively, in CCOG-0902 group, compared with 61.7% and 89.4% respectively, in CCOG-0801 group. Median PFS was 13.6 and 30.5 months, respectively, compared with 11.7 and 31.6 months, respectively, in CCOG-0801 group (p=not significant). The frequency of peripheral sensory neuropathy (PSN) was 19.0% (>Grade3: 1.9%) of patients in CCOG-0902 group compared with 72.3% (>grade 3: 17.0%) in CCOG-0801 group. Conclusions: CapeOX plus BV with oxaliplatin stop and go strategy could have same efficacy as continuing oxaliplatin with avoiding PSN. Clinical trial information: UMIN000006478.

e14552 Background: XELOX plus bevacizumab (BEV) is an established first line therapy for metastatic colorectal cancer (mCRC). However, the cumulative neurotoxicity of oxaliplatin often requires therapy to be discontinued while the patient is still responding. The aim of this study was to evaluate efficacy and safety of XELOX plus BEV with oxaliplatin stop and go strategy. Methods: Fifty four patients with unresectable mCRC were enrolled as first line treatment. They were treated with four cycles of XELOX plus BEV, followed by maintenance therapy with capecitabine (Cape) plus BEV. Reintroduction of oxaliplatin was scheduled after eight cycles of Cape plus BEV or upon tumor progression. The primary endpoint was progression free survival (PFS). Results: Forty nine patients (90%) achieved to the maintenance therapy and thirty two patients (59%) were reintroduced oxaliplatin. After a median follow-up time of 24.2 months, median PFS was 13.4 months (95%CI: 11.7-15.1), median duration of disease control was 13.8 months (95%CI: 11.6-16.0) and median overall survival was 29.0 months (95%CI: 23.1-34.9). The response rate and disease control rate were 57.4% and 96.3% in the initial XELOX plus BEV therapy, 6.1% and 73.5% in Cape plus BEV maintenance therapy, and 0% and 72.4% in reintroduced XELOX plus BEV therapy. The incidence of neuropathy was 38% in initial therapy, 33% in maintenance therapy and 43% in reintroduced therapy. Conclusions: XELOX plus bevacizumab therapy with oxaliplatin stop-and-go strategy was feasible to maintain long disease control without increasing severe neurotoxicity in first-line treatment for mCRC.

LBA3500^ Background: Therapy targeting VEGF or EGFR demonstrated clinical activity in combination with chemotherapy (CT) in mCRC but monoclonal antibodies cannot be associated. The DREAM trial compares a maintenance therapy (MT) with bev +/- EGFR tyrosine kinase inhibitor erlotinib (E) after a first-line Bev-based induction therapy (IT) in pts with mCRC. Methods: Pts with previously untreated and unresectable mCRC were eligible. After a Bev-based IT with FOLFOX or XELOX or FOLFIRI, pts without disease progression were randomized to MT between Bev alone (Bev 7.5 mg/kg q3w; arm A) or Bev+E (B 7.5 mg/kg q3w, E 150 mg/day continuously; arm B). Pts were treated until progression or unacceptable toxicity. The primary endpoint was PFS on MT. Results: The study enrolled 700 pts from 01/2007 to 11/2011 in 3 countries (France, Canada, Austria). 446 (63.7%) pts were randomized for MT (arm A, N=224; arm B, N=222). Among the 446 randomized pts, IT regimen was FOLFOX-Bev in 265 pts (59.4%), XELOX-Bev in 135 pts (30.3%), and FOLFIRI-Bev in 46 pts (10.3%). Baseline characteristics of randomized pts were (arm A/B): ECOG PS 0, 60% in both arms; normal LDH level 47%/49%; normal alkaline phosphatase level 48%/50%; synchronous metastasis 83%/82%. The median no of MT cycles was 6 in both arms. With a median follow-up of 31.0 months, 327 PFS events were observed. Median MT-PFS were 4.6 m in arm A vs 5.8 m in arm B (HR 0.73 [95%CI: 0.59-0.91], P=.005). Median PFS from inclusion were 9.2 m vs 10.2 m. During MT, in arm A vs arm B, grade 3-4 diarrhea (<1% vs 9%) and grade 3 skin toxicity (0% vs 19%) were the main differences in toxicity. Severe adverse events from randomization related to B or E were 6 in arm A and 7 in arm B. Overall survival is not mature. Conclusions: The addition of erlotinib to bevacizumab after induction therapy significantly improves the duration of maintenance PFS, following induction with first-line chemotherapy plus bevacizumab, in patients with unresectable metastatic colorectal cancer.
