646 Background: TAS-102 is comprised of an antineoplastic thymidine-based nucleoside analog, trifluridine, and the thymidine phosphorylase inhibitor, tipiracil hydrochloride, at a molar ratio of 1:0.5 (weight ratio, 1:0.471). The efficacy and safety of TAS-102 in patients (pts) with metastatic colorectal cancer refractory/intolerant to standard therapies were evaluated in the RECOURSE trial; enrollment criteria included ≥ 2 prior lines of standard chemotherapy. Primary results of RECOURSE demonstrated a significant improvement in overall survival (OS) and progression-free survival (PFS) with TAS-102 vs placebo (PBO) (hazard ratio [HR] = 0.68 and 0.48 for OS and PFS, respectively; both P< 0.0001). Methods: RECOURSE data were evaluated for efficacy and safety, including rate of hospitalizations, of TAS-102 vs PBO by each geographic subgroup of US, EU, and Japan (JP). Results: Of 768 pts, 99 US (mean age, 60 y), 403 EU (mean age, 62 y), and 266 JP (mean age, 62 y) pts were randomized to receive TAS-102 or PBO. Median OS with TAS-102 vs PBO was 6.5 mo vs 4.3 mo in US pts, 6.8 mo vs 4.9 mo in EU pts, and 7.8 mo vs 6.7 mo in JP pts. HRs for OS and PFS for US, EU, and JP pts all favored TAS-102 (Table). There were no marked differences among the US, EU, and JP subgroups with respect to overall incidence of adverse events (AEs), ≥ Grade 3 AEs, serious AEs (SAEs), or hospitalizations. Conclusions: Similar to the overall RECOURSE population, OS and PFS benefits were observed in each geographic subgroup randomized to TAS-102 vs PBO, with an acceptable safety profile. Clinical trial information: NCT01607957. [Table: see text] [Table: see text]

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.

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.

Colorectal cancer is the third most common cancer in the US. In recent decades, an improved understanding of the role of the angiogenesis pathway in colorectal cancer has led to advancements in treatment. Bevacizumab has been shown to improve the progression-free survival and overall survival when combined with cytotoxic chemotherapy in patients with metastatic colorectal cancer, and at present is the only antiangiogenesis agent approved for the treatment of this cancer. Aflibercept is a novel angiogenesis-targeting agent, and has demonstrated efficacy in treating metastatic colorectal cancer in a recent randomized Phase III trial. Here we review the role of angiogenesis in the tumorigenesis of colorectal cancer, strategies for targeting angiogenesis, and the clinical development of aflibercept.

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.

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.

638 Background: TAS-102 is comprised of an antineoplastic thymidine-based nucleoside analog, trifluridine, and the thymidine phosphorylase inhibitor, tipiracil hydrochloride, at a molar ratio of 1:0.5 (weight ratio, 1:0.471). Efficacy and safety of TAS-102 in pts with mCRC refractory to standard therapies were evaluated in the RECOURSE trial; enrollment criteria included ≥2 prior lines of standard chemotherapy. Primary results of RECOURSE demonstrated a significant improvement in overall survival (OS) (TAS-102 7.1 mo vs PBO 5.3 mo; HR=0.68; P<0.0001) and progression-free survival (PFS) (HR=0.48; P<0.0001). Methods: This prespecified analysis compared the efficacy and safety of TAS-102 vs PBO in pts ≥65 y and <65 y with mCRC. A retrospective analysis of pts ≥75 y was also performed. Results: Of 800 randomized pts, 352 (44.0%) were ≥65 y and 60 (7.5%) were ≥75 y. Median OS in pts ≥65 y was 7.0 mo with TAS-102 vs 4.6 mo with PBO (HR=0.62, 95% CI: 0.48-0.80, P=0.0002). PFS HR was 0.41 (95% CI: 0.32-0.52, P<0.0001) for pts ≥65 y, also favoring TAS-102. In pts ≥65 y, disease control rate (complete or partial response or stable disease) was 48.7% with TAS-102 vs 15.5% with PBO. An age-related difference in overall incidence of adverse events (AEs) was not observed in either treatment arm. Treatment-related AEs, ≥ Grade 3 AEs, and severe AEs were generally more common in pts ≥65 y than in pts <65 y (Table). Mean drug exposure was similar among pts ≥65 y and ≥75 y, as was overall safety profile. Conclusions: Significant improvements in OS and PFS were observed in pts ≥65 y who received TAS-102 vs PBO, with a mild increase in toxicity. Pts ≥65 y and <65 y showed a generally favorable safety profile. A significant increase in toxicity in pts ≥75 y was not apparent vs the overall ≥65 y population.

795 Background: The aim of this study was to evaluate the efficacy and safety of CapeOX plus bevacizumab with a planned oxaliplatin stop-and-go strategy in Japanese patients with metastatic colorectal cancer (mCRC). Methods: Patients with untreated mCRC were treated with 4 cycles of CapeOX plus bevacizumab therapy, followed by capecitabine plus bevacizumab maintenance therapy. Reintroduction of oxaliplatin was scheduled after 8 cycles of maintenance therapy or upon tumor progression. The primary endpoint was progression-free survival (PFS), and secondary end points included overall survival (OS), objective response rate to each treatment, reintroduction rate of oxaliplatin, frequency of peripheral sensory neuropathy (PSN), and safety. Results: The 52 patients who received the protocol treatment were included in the evaluation of efficacy and safety. Median PFS and OS were 12.4 months (95% confidence interval [CI], 10.0–14.8) and 30.6 months (95% CI, 27.6–33.5), respectively. The objective response rates were 55.8% for the initial CapeOX plus bevacizumab therapy, 17.8% for capecitabine plus bevacizumab maintenance therapy, and 31.0% for reintroduced CapeOX plus bevacizumab therapy. The frequency of PSN was 63.5%, including 3.8% of patients with grade 3 PSN. No patients required treatment discontinuation because of PSN during the induction or maintenance therapy. Conclusions: CapeOX plus bevacizumab therapy with a planned oxaliplatin stop-and-go strategy is a feasible first-line treatment for Japanese patients with mCRC.

Purpose This double-blind, phase III study aimed to demonstrate that sunitinib plus FOLFIRI (fluorouracil, leucovorin, and irinotecan) was superior to placebo plus FOLFIRI in previously untreated metastatic colorectal cancer (mCRC). Patients and Methods Patients were randomly assigned to receive FOLFIRI and either sunitinib (37.5 mg per day) or placebo (4 weeks on treatment, followed by 2 weeks off [schedule 4/2]) until disease progression. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, safety, and patient-reported outcomes. The correlation between genotype and clinical outcomes was also analyzed. Results In all, 768 patients were randomly assigned to sunitinib plus FOLFIRI (n = 386) or placebo plus FOLFIRI (n = 382). Following a second prespecified interim analysis, the study was stopped because of potential futility of sunitinib plus FOLFIRI. Final results are reported. The PFS hazard ratio was 1.095 (95% CI, 0.892 to 1.344; one-sided stratified log-rank P = .807), indicating a lack of superiority for sunitinib plus FOLFIRI. Median PFS for the sunitinib arm was 7.8 months (95% CI, 7.1 to 8.4 months) versus 8.4 months (95% CI, 7.6 to 9.2 months) for the placebo arm. Sunitinib plus FOLFIRI was associated with more grade ≥ 3 adverse events and laboratory abnormalities than placebo (especially diarrhea, stomatitis/oral syndromes, fatigue, hand-foot syndrome, neutropenia, thrombocytopenia, anemia, and febrile neutropenia). More deaths as a result of toxicity (12 v four) and significantly more dose delays, dose reductions, and treatment discontinuations occurred in the sunitinib arm. Conclusion Sunitinib 37.5 mg per day (schedule 4/2) plus FOLFIRI is not superior to FOLFIRI alone and has a poorer safety profile. This combination regimen is not recommended for previously untreated mCRC.

Abstract We evaluated the efficacy and safety of trifluridine/tipiracil (TAS-102) plus bevacizumab in treating refractory metastatic colorectal cancer (mCRC) in a retrospective, observational study. Patients refractory or intolerant to standard therapies received TAS-102 (30–35 mg/m2 twice daily on days 1–5 and days 8–12 every 28 days) plus bevacizumab 5 mg/kg on days 1 and 15. Clinical and pathological characteristics, overall response rate (ORR) and disease control rate (DCR), overall survival (OS) and progression-free survival (PFS) data were collected and analysed. Thirty-five patients were treated from July 2019 to October 2021 (median age 64 years). The majority of patients (68.6%) were receiving TAS-102 plus bevacizumab as third-line treatment. Patients received a median of 4 (range 2–15) cycles of treatment. Among 31 patients evaluable for response (88.6%), ORR and DCR were 3.2% and 51.6%, respectively. After a median 11.6 months’ follow-up, median PFS was 4.3 (95% confidence interval [CI] 3.4–5.1) months and median OS was 9.3 (95% CI 6.6–12.1) months. The most common grade 3–4 toxicities were neutropenia, asthenia and nausea/vomiting, and there were no treatment-related deaths. This real-world study confirms the efficacy and safety of TAS-102 plus bevacizumab in patients with refractory mCRC.
