3519 Background: Several studies of oxaliplatin plus S-1 combination therapy (SOX) conducted in Asia have shown promising efficacy and safety for metastatic colorectal cancer (mCRC), suggesting the potential to replace mFOLFOX6. We performed a randomized phase III trial to determine whether SOX plus bevacizmab (SOX+Bev) is non-inferior to mFOLFOX6 plus bevacizmab (mFOLFOX6+Bev) in terms of progression-free survival (PFS). Methods: The SOFT study was a randomized, open-label, phase III trial. Chemotherapy-naïve patients (pts) with mCRC, an ECOG PS of 0-1, and adequate organ functions were randomized to receive either mFOLFOX6+Bev (5 mg/kg of bevacizumab, followed by 200 mg/m2 of l-leucovorin given simultaneously with 85 mg/m2 of oxaliplatin, followed by a 400 mg/m2 bolus of 5-FU on day 1 and then 2,400 mg/m2 of 5-FU over 46 h, every 2 weeks) or SOX+Bev (7.5 mg/kg of bevacizumab, 130 mg/m2 of oxaliplatin on day 1, and 40−60 mg of S-1 twice daily for 2 weeks, followed by a 1-week rest). The primary endpoint was PFS. A sample size of 225 pts per group was estimated to be necessary based on a median PFS of 10.0 months in each group and an 80% power to demonstrate non-inferiority of SOX+Bev with a 2.5-month margin (hazard ratio, HR = 1.33) and a 2-sided alpha of 0.05. Results: A total of 512 pts were enrolled from February 2009 to March 2011. Data were analyzed after confirming >388 events as planned. Demographic factors were well balanced. Pts received a median of 12 cycles (1 cycle = 2 weeks) of mFOLFOX6+Bev and 8 cycles (1 cycle = 3 weeks) of SOX+Bev (range: 1−16). Median PFS was 11.5 months (95% CI: 10.7−13.2) with mFOLFOX6+Bev and 11.7 months (95% CI: 10.7−12.9) with SOX+Bev. The adjusted HR for PFS was 1.043 (95% CI: 0.860−1.266), and the p value for non-inferiority was 0.0139. Response rate was 62.7% with mFOLFOX6+Bev and 61.5% with SOX+Bev. Grade 3/4 toxicities (%) with mFOLFOX6+Bev/SOX+Bev were leukopenia 8.4/2.4, neutropenia 33.7/8.8, anorexia 1.2/5.2, and diarrhea 2.8/9.2. Conclusions: SOX+Bev is non-inferior to mFOLFOX6+Bev with respect to PFS as 1st-line treatment for mCRC and thus can replace mFOLFOX6+Bev. Clinical trial information: JapicCTI-090699.

Purpose The Gruppo Oncologico Nord Ovest (GONO) conducted a phase III study comparing fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI [irinotecan 165 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 200 mg/m2 day 1, fluorouracil 3,200 mg/m2 48-hour continuous infusion starting on day 1, every 2 weeks]) with infusional fluorouracil, leucovorin, and irinotecan (FOLFIRI). Methods Selection criteria included unresectable metastatic colorectal cancer, age 18 to 75 years, and no prior chemotherapy for advanced disease. The primary end point was response rate (RR). Results A total of 244 patients were randomly assigned. An increase of grade 2 to 3 peripheral neurotoxicity (0% v 19%; P < .001), and grade 3 to 4 neutropenia (28% v 50%; P < .001) were observed in the FOLFOXIRI arm. The incidence of febrile neutropenia (3% v 5%) and grade 3 to 4 diarrhea (12% v 20%) were not significantly different. Responses, as assessed by investigators, were, for FOLFIRI and FOLFOXIRI, respectively, complete, 6% and 8%; and partial, 35% and 58%, (RR, 41% v 66%; P = .0002). RR confirmed by an external panel was 34% versus 60% (P < .0001). The R0 secondary resection rate of metastases was greater in the FOLFOXIRI arm (6% v 15%; P = .033, among all 244 patients; and 12% v 36%; P = .017 among patients with liver metastases only). Progression-free survival (PFS) and overall survival (OS) were both significantly improved in the FOLFOXIRI arm (median PFS, 6.9 v 9.8 months; hazard ratio [HR], 0.63; P = .0006; median OS, 16.7 v 22.6 months; HR, 0.70; P = .032). Conclusion The FOLFOXIRI regimen improves RR, PFS, and OS compared with FOLFIRI, with an increased, but manageable, toxicity in patients with metastatic colorectal cancer with favorable prognostic characteristics. Further studies of FOLFOXIRI in combination with targeted agents and in the neoadjuvant setting are warranted.

538 Background: Aflibercept (AF), a recombinant fusion protein, is a potent inhibitor of vascular endothelial growth factor. This study assessed the safety, dose limiting toxicities (DLTs), recommended dose (RD), and the pharmacokinetics (PK) of AF in combination with FOLFIRI. Methods: This was an open-label, sequential-cohort, dose-escalation study of intravenous AF administered every 2 weeks, in combination with FOLFIRI (fixed doses) in patients (pts) with metastatic colorectal cancer (MCRC). Two dose levels (DL) of AF (2 and 4 mg/kg) were set, and 3-6 pts were to be recruited in each DL. DLTs were to be evaluated in the first 2 cycles. RD was defined as the highest AF dose at which <33% of all evaluable pts experienced DLTs. After establishment of RD, 10 additional pts were treated at RD. PK of AF, irinotecan, SN38, and 5-FU were studied in cycle 1. Results: 16 pts (3 at 2 mg/kg and 13 at 4 mg/kg) with MCRC were treated (M/F, 10/6; median age, 57.0 [47-69]; and ECOG PS 0/1, 9/7), and all had received prior chemotherapies. A total of 131 cycles of AF + FOLFIRI were administered at the two DLs of AF (2 and 4 mg/kg). No DLT was observed. The most common all-causality grade 3/4 adverse events were neutropenia (75.0 %) including one febrile neutropenia after DLT evaluation period and hypertension (25.0%). There was no major safety issue at the RD. Response rate and progression free survival at RD (N=13 pts) was 7.8% and 7.6 month, respectively. Conclusions: RD was determined as 4 mg/kg in this first clinical study of AF in Japanese pts with MCRC. The combination of AF (4 mg/kg) and FOLFIRI was well tolerated in line with results of prior overseas studies. The PK results in Japanese patients showed similar tendency to those reported in patients from other regions of the world. [Table: see text]

3532 Background: Linifanib is a potent and selective inhibitor of VEGF/PDGF receptors. This trial assessed the efficacy and safety of mFOLFOX6 in combination with linifanib or bevacizumab as second-line treatment for metastatic colorectal cancer (mCRC). Methods: Patients (pts) with measurable mCRC refractory to 1 prior regimen and ECOG PS 0–1, stratified by prior bevacizumab treatment and radiotherapy, were randomized to receive mFOLFOX6 with bevacizumab 10 mg/kg on day (d) 1 of 14-d cycle (Arm A), mFOLFOX6 with daily linifanib 7.5 mg (Arm B), or mFOLFOX6 with daily linifanib 12.5 mg (Arm C). The primary endpoint was progression-free survival (PFS). Severity of adverse events (AEs) was graded using NCI-CTCAE v3.0. Results: 148 pts were randomized at 45 sites in 14 countries. 32 pts (21.6%) had received prior bevacizumab. PFS and response data are shown below (Table). Median survival (OS) was not reached at median follow up 7.6 months. Palmar-plantar erythrodysesthesia (PPE) was the only Grade 3/4 AE significantly higher on linifanib (high dose, 16.3%) vs. bevacizumab (0%). Rate of any Grade 3+ AE was significantly higher on linifanib vs. bevacizumab.Hypertension rates were 41.7% (Arm A), 40.0% (Arm B), and 36.7% (Arm C). AEs dose-related to linifanib were constipation, proctalgia, stomatitis, fatigue, weight decrease, decreased appetite, and PPE. Conclusions: The addition of linifanib to mFOLFOX6, compared to mFOLFOX6 + bevacizumab, did not provide a PFS advantage for mCRC. OS results will be updated for conference presentation.

4102 Purpose: To compare oxaliplatin (L-OHP) plus raltitrexed (RTX) with L-OHP plus fluorouracil and leucovorin (LV/5FU) for patients (pts) with recurrent and metastatic colorectal cancer(CRC). Methods: Eligible pts had to have histologically proven recurrent or metastatic CRC,not having previously received oxaliplatin as palliative chemotherapy,ECOG PS = 2,age:18∼70,and adequate hematological,renal and hepatic function.After written informed consent,pts were randomized to L-OHP:130 mg/m2 d1 + RTX: 3 mg/m2 d1 (Arm A) or + LV: 200 mg/m2 + 5FU:375 mg/m2 d1–5 (Arm B). Results: Between Jan 2005 and July 2006, 216 pts were enrolled at 15 centers in China.112 pts (mean age: 55.0 (19∼70), M/F: 57/46, PS 0/1/2: 46/53/13) were randomly assigned to A and 102 (mean age: 54.2(22∼70), M/F: 54/46, PS 0/1/2: 44/59/9) to B. 203 pts were eligible for response evaluation (A:103, B:100).The median number of cycles was 4 (1∼6) in A and 3 (1∼6) in B (P=0.1431).The RR was 29.1% (CR:2, PR:28, SD:50 , PD:23) in A and 17.0% (CR:2, PR:15, SD:46 , PD:37) in B (P=0.0437).The disease-control rate was 77.7% in A and 63.0% in B (P=0.0237). After a median follow-up of 10 months (4–16.5),92 pts had had progression of disease (40 in A and 52 in B); 73 deaths had occurred (35 in A and 38 in B), median time to progression was not reached. Following-up is ongoing.The median QoL scores for the two arms were comparable. 214 were included in the safety analyses (A:112, B:102). There was a higher incidence of neutropenia (48.2% verse 29.4%, P=0.005) and transaminase increase (49.1% verse 35.3%, P=0.041) among A. Grade 3 or 4 neutropenia was much common in pts in A than those in B (20.5% verse 4.9% , P=0.001), but was complicated by fever in only 3.6% of cases (4 pts) in A and in 2.9% of cases (3 pts) in B. No pts were dead or infectious due to neutropenia. There were similar rates of grade 3 or 4 transaminase elevation in the two groups. Vomitting and anorexia were much commoner with B. Conclusions: The L-OHP+RTX seems beneficial in recurrent and metastatic CRC, demonstrating better response rate and higher disease control rate with acceptable tolerability, maintenance of QoL and convenient administration schedule.

e15138 Background: Bevacizumab (BEV) has shown clinical activity in metastatic colorectal cancer patients (mCRC)and randomised phase III trials have demonstrated that this agent significantly improves overall and/or progression-free survival when added to first-line irinotecan based chemotherapy (CT) regimens. We evaluated the efficacy and safety of BEV plus FOLFIRI (irinotecan, 5- fluorouracil, and leucovorin) as first line treatment in 27 consecutive metastatic colorectal cancer cases, with the primary end point to calculate the median time to clinical response with this chemotherapeutic schedule. Methods: Between October 2007 and January 2008 we collected the data on 27 patients with mCRC treated with first line chemotherapy with BEV plus FOLFIRI. Elegibility criteria had to be: mCRC; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. The treatment consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI schedule; BEV (5mg/kg) was given on day 1 with CT and then every 2 weeks until disease progression. Safety and response were assessed at the time of first CT and every 4 weeks thereafter. Results: 27 pts were evaluable (male 18; median age 61 years (range 45–77), ECOG PS 0: 52%, PS 1: 48%. The sites of metastases were: liver (15 pts), lung (5 pts), liver and lung (5 pts), peritoneal wall (2 pts).Median follow-up was 18 weeks. Two patients had complete response(CR) and 13 pts partial response (PR), with an overall response rate of 57.7%. Five patients had stable disease and 6 patients showed progressive disease. A clinical benefit was demonstrated in 77 % of pts. We observed a median time to clinical response of 11 weeks, evaluated with tumor markers and with CT/NMR/US examinations. A grade 3 or 4 neutropenia was detected in 39% of pts and grade 2 or 3 hypertension in 9%. We did’nt observe cases of thrombosis, bleeding and gastrointestinal perforation, sometimes related to the use of BEV. Conclusions: In this little experience the efficacy and safety of BEV associated with FOLFIRI schedule, a first line therapy in mCRC,is consistent with results from other previous studies, showing moreover a short time to clinical response with this association. No significant financial relationships to disclose.

TPS4692^ Background: The phase III TROPIC study (NCT00417079) reported a significant improvement in overall survival (OS) for cabazitaxel (Cbz) + prednisone (P;CbzP) (25 mg/m2 IV Q3W/10 mg PO QD) vs mitoxantrone (M) + P (MP) (median OS 15.1 vs 12.7 mos; HR 0.70; P < 0.0001) in pts with mCRPC (also known as hormone-refractory prostate cancer) previously treated with a D-containing regimen. CbzP is approved by the FDA, EMA and other health authorities for the treatment of pts with mCRPC that has progressed after a D-containing regimen. Cbz toxicity is consistent with other taxanes; compared with M, more hematologic toxicities are reported (primarily Grade 3–4 neutropenia). Phase I/II studies identified 20 and 25 mg/m2 as recommended doses; 25 mg/m2 was selected for the phase III TROPIC study. As pooled data show Grade 3–4 neutropenia incidence is lower with Cbz < 25 mg/m2 (61%) vs ≥ 25 mg/m2 (74%), it is of interest to assess if reducing the Cbz approved dose in mCRPC lessens hematologic toxicity and is non-inferior in terms of efficacy. Methods: PROSELICA (NCT01308580) is a randomized, open-label, multinational, phase III study comparing 20 mg/m2 and 25 mg/m2 Cbz for efficacy and tolerability. Pts with a life expectancy > 6 mos, ECOG PS ≤ 2, histologically/cytologically confirmed metastatic prostate adenocarcinoma resistant to hormone therapy and previously treated with a D-containing regimen are eligible. Pts are randomized 1:1 to receive Cbz 20 mg/m² or 25 mg/m² IV Q3W + P 10 mg PO QD, treated until disease progression, unacceptable toxicity or withdrawal of consent (max 10 cycles), and stratified according to ECOG PS, measurable disease (yes/no) and region. The primary endpoint is OS (non-inferiority design). Secondary endpoints include safety, progression-free survival (PCWG2 criteria), PSA and pain progression and response, tumor response in pts with measurable disease and health-related quality of life. Cbz PK and pharmacogenomics will be assessed in pt subgroups. Planned enrollment is 1,200 pts. Study start was in May 2011; as of Jan 2012, 270 pts had been enrolled. The first DMC meeting recommended continuing the study without change.

3619^ Background: Patients (pts) with unresectable colorectal cancer liver-only metastases (CLMs) may become resectable after downsizing by chemotherapy (CT) and biologic therapy. Although biologics are thought to improve overall response rate (ORR), the optimal combination of a biologic and CT for resectability remains uncertain. Methods: This open-label, multinational study randomized pts with unresectable CLMs to bevacizumab (BEV) plus mFOLFOX6 or FOLFOXIRI q2w. Resectability was assessed by interdisciplinary review. Unresectability was defined as ≥1 of the following: no possibility of upfront R0/R1 resection of all hepatic lesions, <30% estimated residual liver after resection, or disease in contact with major vessels of the remnant liver. The primary end point was overall resection rate (R0/R1/R2). Results: From 10/2008 to 12/2011, 80 pts were randomized to mFOLFOX6-BEV (n=39) or FOLFOXIRI-BEV (n=41). Pt characteristics were male (46% vs 71%), aged ≥60 y (36% vs 63%), ECOG PS of 1 (23% vs 37%), and ≥5 target CLMs (49% vs 49%) in the mFOLFOX6-BEV and FOLFOXIRI-BEV arms, respectively. Resection rate, ORR, and progression-free survival (PFS) data are shown (Table). Grade ≥3 adverse events (AEs) occurred in 84% and 95% of pts receiving mFOLFOX6-BEV and FOLFOXIRI-BEV, respectively, and included neutropenia (35% vs 48%; febrile, 8% vs 13%) and diarrhea (14% vs 28%). Conclusions: The results suggest that FOLFOXIRI-BEV improves resection rates, ORR, and long-term outcomes vs mFOLFOX6-BEV in pts with initially unresectable CLMs. CT- and BEV-related AEs occurred with the expected incidence and were manageable. FOLFOXIRI-BEV should be evaluated further as an effective regimen to downsize CLMs. Clinical trial information: NCT00778102. [Table: see text]
