BackgroundLenvatinib inhibits tyrosine kinases, including vascular endothelial growth factor (VEGF) receptor, fibroblast growth factor receptor, platelet-derived growth factor receptor alpha, RET proto-oncogene and KIT proto-oncogene, receptor tyrosine kinase. We assessed the efficacy and safety of lenvatinib in patients with metastatic colorectal cancer after failure of standard chemotherapies.Patients and methodsThis was an open-label, single centre, single-arm, phase 2 study. Eligible patients had unresectable metastatic colorectal adenocarcinoma, refractory or intolerant to fluoropyrimidine, irinotecan, oxaliplatin, trifluridine/tipiracil, anti-VEGF therapy and anti-epidermal growth factor receptor therapy (for tumours with wild-type RAS). Patients were treated with oral lenvatinib at 24 mg one time a day in 28-day cycles until disease progression or unacceptable toxicity. The primary endpoint was centrally assessed disease control rate. Secondary endpoints included safety, response rate, progression-free survival and overall survival. The planned sample size was 30 patients to expect a disease control rate of 60% with a threshold disease control rate of 35%, one-sided alpha of 5% and power of 80%ResultsBetween 24 October 2016 and 23 January 2018, 30 patients were enrolled; 11 (37%) and 19 (63%) had received 3 or ≥4 lines of prior chemotherapy for metastatic disease, respectively. The median number of lenvatinib cycles was 4 (range 1–13). The centrally assessed disease control rate was 70.0% (21/30, 90% CI 53.5% to 83.4%, one-sided p=0.0001); 2 patients had a partial response and 19 had a stable disease. Median progression-free survival was 3.6 months (95% CI 2.6 to 3.7). Median overall survival was 7.4 months (95% CI 6.4 to 10.8). The most common grade ≥3 adverse events were hypertension (53%), thrombocytopenia (10%), increased alanine aminotransferase and anorexia (7% each).ConclusionsLenvatinib showed promising clinical activity and was tolerated in patients with metastatic colorectal cancer after failure of standard chemotherapies.Trial registration numberUMIN-CTR, UMIN000023446 and JAMCCT-CTR, JMA-IIA00261.

3527 Background: Apatinib is an oral highly-selective tyrosine kinase inhibitor (TKI) that blocks vascular endothelial growth factor receptor 2 (VEGFR-2). This exploratory study evaluated the efficacy and safety of apatinib monotherapy in patients with chemotherapy-refractory metastatic colorectal cancer. Methods: In this multicenter, single-arm, prospective study, 48 patients with metastatic colorectal cancer who had failed at least two lines standard chemotherapies including fluorouracil, oxaliplatin and irinotecan were recruited from 14 centers in Guangdong, China. Apatinib at a 500mg dose was administered daily continuously. Each cycle was 4 weeks (28 days). The primary endpoint was progression free survival (PFS). Secondary end points included overall survival (OS), objective response rate (ORR), disease control rate (DCR), quality of life (QoL) and toxicity. Results: A total of 48 patients was enrolled in the study from September 3, 2015 to June9, 2017. Four patients achieved a partial response, and 22 achieved stable disease, representing a response rate of 8.3% and a disease control rate of 60.4%. Median follow-up time was 10.3 months. Median progression-free survival (PFS) and overall survival (OS) of evaluable patients (n=41) were 4.7 months (95% confidence interval [CI] 3.7-5.9) and 9.7 months (95% CI 5.9-13.6). The most common grade 3 or 4 adverse events (AE) were hypertension (12.5%), hand-foot syndrome (10.4%), thrombocytopenia (10.4%), proteinuria (8.3%) and mucositis oral (6.3%). Conclusions: Apatinib monotherapy shows promising efficacy and manageable toxicities in patients with chemotherapy-refractory metastatic colorectal cancer. Further phase 3 trial is warranted.

Purpose Treatment for metastatic colorectal cancer (mCRC) commonly involves a fluoropyrimidine-based chemotherapy regimen such as infusional fluorouracil, leucovorin, and irinotecan (FOLFIRI) or fluorouracil, leucovorin, and oxaliplatin, often combined with bevacizumab or an epidermal growth factor receptor monoclonal antibody. We studied the effect of adding the novel antiangiogenic agent aflibercept (also known as ziv-aflibercept in the United States) to FOLFIRI in patients with mCRC previously treated with oxaliplatin, including patients who received prior bevacizumab. Patients and Methods Patients were randomly assigned to receive aflibercept (4 mg/kg intravenously; 612 patients) or placebo (614 patients) every 2 weeks in combination with FOLFIRI. Treatment was administered until disease progression or unacceptable toxicity. The primary end point was overall survival. Results Adding aflibercept to FOLFIRI significantly improved overall survival relative to placebo plus FOLFIRI (hazard ratio [HR], 0.817; 95.34% CI, 0.713 to 0.937; P = .0032) with median survival times of 13.50 versus 12.06 months, respectively. Aflibercept also significantly improved progression-free survival (PFS; HR, 0.758; 95% CI, 0.661 to 0.869; P < .0001), with median PFS times of 6.90 versus 4.67 months, respectively. The effects on overall survival and PFS exhibited a consistent trend across prespecified subgroup analyses, including bevacizumab pretreated patients. Response rate was 19.8% (95% CI, 16.4% to 23.2%) with aflibercept plus FOLFIRI compared with 11.1% (95% CI, 8.5% to 13.8%) with placebo plus FOLFIRI (P = .0001). Adverse effects reported with aflibercept combined with FOLFIRI included the characteristic anti–vascular endothelial growth factor effects and also reflected an increased incidence of some chemotherapy-related toxicities. Conclusion Aflibercept in combination with FOLFIRI conferred a statistically significant survival benefit over FOLFIRI combined with placebo in patients with mCRC previously treated with oxaliplatin.

There is a lack of useful biomarkers for predicting the efficacy of anti–programmed death-1 (PD-1) therapy for advanced gastric and colorectal cancer. To address this issue, in this study we investigated the correlation between inflammatory marker expression and survival in patients with advanced gastric and colorectal cancer. Data for 111 patients with advanced gastric and colorectal cancer treated with anti–PD-1 regimens were retrospectively analyzed. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and clinical characteristics of each patient were selected as the main variables. Overall response rate, disease control rate, and progression-free survival were primary endpoints, and overall survival and immune-related adverse events (irAEs) were secondary endpoints. The chi-squared test and Fisher’s exact test were used to evaluate relationships between categorical variables. Uni- and multivariate Cox regression analyses were performed, and median progression-free survival and overall survival were estimated with the Kaplan–Meier method. The overall response rate and disease control rate of anti–PD-1therapy in advanced gastric and colorectal tumors were 12.61 and 66.66%, respectively. The patients with MLR &lt; 0.31, NLR &lt; 5, and PLR &lt; 135 had a significantly higher disease control rate than those with MLR &gt; 0.31, NLR &gt; 5, and PLR &gt; 135 (P &lt; 0.05). The multivariate analysis revealed that MLR &lt; 0.31, BMI &gt; 18.5, and anti–PD-1 therapy in first-line were associated with prolonged PFS. MLR &lt; 0.31 and BMI &gt; 18.5 were associated with prolonged overall survival. The irAE rate differed significantly between PLR groups, and PLR &lt; 135 was associated with an increased rate of irAEs (P = 0.028). These results indicate that the inflammatory markers NLR, MLR, and PLR have clinical utility for predicting survival or risk of irAEs in patients with advanced gastric cancer and colorectal cancer.

631 Background: This study was designed to evaluate the influence of dose reduction and schedule modification on outcomes in patients with metastatic colorectal cancer (mCRC). Methods: Pooled datasets from two previous phase II trials of FOLFIRI (CCOG-0502; n = 36) and mFOLFOX6 (CCOG-0704; n = 30) in patients with mCRC were analyzed retrospectively. The RDIs of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). To assess the effects of dose reduction and time delay, we defined ‘dose index (DI)’ as the ratio of the actual delivered total dose to the planned total dose and ‘time index (TI)’ as the ratio of the planned duration to the actual duration of therapy. Relative dose intensity (RDI) was computed by multiplying DI by TI. DI and TI of irinotecan and oxaliplatin were compared to response rate (RR), disease control rate (DCR) and progression-free survival (PFS). Results: In patients receiving FOLFIRI therapy, the median DI and TI of irinotecan were 0.92 and 0.90, respectively. RRs were 59% vs. 12% in the higher vs. lower DI groups (p < 0.01), and 35% vs. 35% in the higher vs. lower TI groups (p = 1.00), respectively. Median PFS was 10.2 vs. 5.0 months in the higher vs. lower DI groups (p < 0.01), and 6.1 vs. 6.7 months in the higher vs. lower TI groups (p = 0.48), respectively. In mFOLFOX6 therapy, the median DI and TI of oxaliplatin were 0.97 and 0.82, respectively. RRs were 44% vs. 36% in the higher vs. lower DI groups (p = 0.65), and 44% vs. 36% in the higher vs. lower TI groups (p = 0.65), respectively. Median PFS was 7.7 vs. 6.7 months in the higher vs. lower DI groups (p = 0.13), and 8.5 vs. 5.9 months in the higher vs. lower TI groups (p = 0.02), respectively. Multivariate analyses showed that DI of irinotecan (HR 8.48; 95% CI, 2.94-24.51, p < 0.01) and TI of oxaliplatin (HR 2.74; 95% CI, 1.02-7.33, p = 0.04) were the independent prognostic factors for PFS. Conclusions: Dose reductions in irinotecan and time delays in oxaliplatin could have significant impact on PFS in patients receiving FOLFIRI and FOLFOX6, respectively.

Backgroundand objectives: Patients with BRAF-mutated metastatic colorectal cancer have considerably poorer responses to conventional systemic treatment. The real-world effects of triplet therapy with BRAF, mitogen-activated protein kinase kinase, and epidermal growth factor receptor inhibitors in Asia have not been well-reported. Materials and Methods: This single-center case series included patients with BRAF-mutated metastatic colorectal cancer undergoing triplet therapy after failure of prior systemic treatment from 2016 to 2020. The primary outcome was progression-free survival, and secondary outcomes were overall survival, response rate, disease control rate, and adverse events. Results: Nine eligible patients with BRAF-mutated metastatic colorectal cancer receiving triplet therapy were enrolled, with a median follow-up time of 14.5 months (range, 1–26). Most patients (88.8%) had two or more prior systemic treatments, and the triplet regimen was mainly dabrafenib, trametinib, and panitumumab. The overall response rate and disease control rate were 11.1% and 33.3%, respectively. Median progression-free survival and overall survival were 2.9 and 7.4 months, respectively, and a trend toward better overall survival was found with left-sided metastatic colorectal cancer compared with right-sided disease (9.2 vs. 6.9 months, p = 0.093). Adverse events were mostly Grade 1–2, including nausea, hypertension, gastrointestinal symptoms, and skin disorders. Conclusions: In this single-center case series, triplet therapy with BRAF, mitogen-activated protein kinase kinase, and epidermal growth factor receptor inhibitors in BRAF-mutated metastatic colorectal cancer had an acceptable safety profile and reasonable efficacy.

588 Background: Bevacizumab (BV) is a recombinant, humanized monoclonal antibody against vascular endothelial growth factor. Used in combination with chemotherapy, BV has been shown to improve survival in both first- and second-line treatment for metastatic colorectal cancer (mCRC). However, it was reported that addition of BV to FOLFOX conferred only little survival benefit (Saltz et al. JCO2008). The aim of this study was to assess the efficacy of addition of BV to FOLFOX in first-line treatment for patients with mCRC. Methods: Bevacizumab was approved for mCRC in July 2007 in Japan. This study was conducted at a single institution and comprised 217 consecutive patients receiving first-line treatment for mCRC between 2005 and 2009. The primary objective was to compare survival benefit in patients treated with FOLFOX4 (FF) between 2005 and 2007 with that in patients receiving FOLFOX4+BV 5 mg/kg (FF+BV) between 2007 and 2009. Results: Total number of patients in the FF and FF+BV groups was 132 and 85, respectively. Characteristics of patients were as follows (FF vs. FF+B): median age, 62 yrs (range 28-76 yrs) vs. 60 yrs (range16-74 yrs); ECOG PS0, 98.8% vs. 81.8%; and median follow-up time, 20.8 months vs. 24.4 months. Median progression-free survival (PFS) in the FF and FF+BV groups was 10 months (95% CI, 8.7-11.3) and 17 months (95% CI, 10.2-14.1), while median overall survival (OS) was 21 months (95% CI, 17.9-24.1) and not reached, respectively. Response rate was 46% (95% CI, 37- 54) in FF, and 62% (95% CI, 51-73) in FF+BV. Addition of BV to FOLFOX4 significantly improved PFS (p=0.002) and OS (p<0.001). Conclusions: The additive effect of BV for first-line FOLFOX was reconfirmed. These data indicate potential survival benefits from the addition of BV to FOLFOX in first-line treatment of mCRC. In addition, PFS may be a sensitive indicator of outcome prior to post-treatment. No significant financial relationships to disclose.
