751 Background: PEP02 is a highly stable nanoliposomal irinotecan. This randomized non-comparative phase II (PEPCOL) study evaluated the efficacy and safety of PEP02 (MM-398) or irinotecan in combination with LV/5-FU in the second-line treatment of metastatic colorectal cancer (mCRC). (EudraCT 2010-020468-39A, NCT01375816). Methods: Patients with unresectable mCRC who had failed one prior oxaliplatin-based first-line therapy were randomly assigned to FUPEP (PEP02 80 mg/m² d1, folinic acid (FA) 400 mg/m² d1, 5-FU 2,400 mg/m² d1-2) or FOLFIRI (FOLFIRI1: irinotecan 180 mg/m² d1, FA 400 mg/m² d1, 5-FU bolus 400 mg/m² d1, 5-FU infusion 2,400 mg/m² d1-2; or modified FOLFIRI3: irinotecan 90 mg/m² d1 and 3, FA 400 mg/m² d1, 5-FU infusion 2,400 mg/m² d1-2). Bevacizumab q2w (5 mg/kg) was allowed in both arms as of June 2012 (TML study report). The primary endpoint was the objective tumor response (OR). Results: Fifty-five patients were randomized (FUPEP, n=28; FOLFIRI, n=27). In the evaluable population (n=50), OR rate were 16.7% (n=4/24) and 11.5% (n=3/26) in the FUPEP and the FOLFIRI arms, respectively. Most common grade 3-4 adverse events reported in the respective FUPEP and the FOLFIRI arms were diarrhea (21% vs 33%), neutropenia (11% vs 30%), mucositis (11% vs 11%), and alopecia (G2: 25% vs 26%). Conclusions: FUPEP regimen exhibits promising tumor response and safety profile, and can be combined with bevacizumab, for oxaliplatin-pretreated patients. Hence PEP02 (MM-398) may provide a new second-line treatment option for mCRC. Based on the safety profile of the FUPEP regimen in this PEPCOL study, it was added as the third arm to the positive phase III metastatic pancreatic cancer (NAPOLI-1) study. Clinical trial information: NCT01375816.

428 Background: The aim of this study was to evaluate the association of early tumor response to the first-line bevacizumab (BEV) combination therapy with efficacy of the subsequent therapies and survival during the BEV beyond progression (BBP) strategy for metastatic colorectal cancer (mCRC) patients. Methods: We analyzed a pooled data set from the previous phase II studies of mCRC, testing BBP strategy with the first-line mFOLFOX plus BEV (N=47) and the second-line FOLFIRI plus BEV (N=31). Patients were classified into either responders (R group, n=29) with tumor shrinkage (complete response [CR] + partial response [PR]), sub-responders (SR group, n=11) with stable disease (SD) and non-responders (NR group, n=5) with disease progression (PD) at the point of initial three months of the first-line therapy. The tumor response and PFS in the subsequent therapies and OS were evaluated. Results: In the first-line FOLFOX+BEV therapy, further tumor shrinkage was not achieved after the initial three months. PFS was 15.0 months for the R group, 8.9 months for the SR group and 2.9 months for the NR group, respectively, and there was statistical significance favoring the R group (p=0.001). In the second-line FOLFIRI+BEV, RR and DCR were 39 and 78% in the R group, 14 and 57% in the SR group, and 0 and 0% in the NR group, respectively. No additional response to the first-line therapy was observed in all groups, except for only one patient in the SR group. PFS was 8.8 months for the R group, 6.0 months for SR group and 1.4 months for NR group, respectively, and the R group was significant predictor for prolonged PFS in the second-line setting. OS were 30.8 months for the R group, 24.7 months for the SR group, and 11.1 months for the NR group, respectively. Early disease control (R+SR) was significant predictor for OS (hazard ratio [HR]: 8.48, p<0.01) in multivariate analysis. Conclusions: These findings indicate that the tumor response within initial three months of first-line BEV combination chemotherapy could predict efficacies of subsequent treatments and OS in the BBP strategy for mCRC patients.

The addition of aflibercept to FOLFIRI has been demonstrated to improve survival in patients with metastatic colorectal cancer (mCRC) who progressed after receiving a standard oxaliplatin-based regimen. In this retrospective, single-institution, observational study we collected clinical data from mCRC patients who received aflibercept in combination with FOLFIRI in routine clinical practice from October 2012 to March 2021 to describe feasibility and efficacy of this regimen in a real-world population. Forty-nine patients receiving aflibercept-FOLFIRI as second-line treatment were identified, 40.8% of whom were aged over 65 years. The majority of patients had multi-organ metastases (73.5%), and had previously received bevacizumab in combination with chemotherapy (CT) as first-line treatment (79.6%). Median overall survival (OS) and progression-free survival (PFS) were 13 and 6 months, respectively; overall response rate (ORR) and disease control rate (DCR) were 12.3% and 49.1%, respectively. Several factors were associated with survival in univariate analysis, including PFS in first-line therapy, number of metastatic sites, bone metastases and others. However, in multivariate analysis, but only PFS in first-line CT over 12 months was significantly associated with better OS (HR 0.32; 95% CI 0.13–0.79; p = 0.01). Hypertension was the most commonly reported grade (G) 3–4 adverse event (AE), affecting 18.4% of the overall population. Thromboembolic events were observed in 16.3% of patients, hemorrhagic events in 10.2%, and proteinuria in 8.2%. Neutropenia was the most frequently observed hematological G3–4 AE with an incidence of 10.2%. Aflibercept-FOLFIRI has been confirmed as a feasible second-line treatment for mCRC in a real-life setting, and PFS in first-line therapy >12 months resulted as the only predictive marker of better survival.

Background: Pre-treated patients with first-line treatment can be offered a second treatment with the aim of improving their poor clinical prognosis. The therapy of metastatic colorectal cancer (CRC) patients who did not respond to first-line therapy has limited treatment options. Recently, many studies have paid much attention to the efficacy of bevacizumab as an adjuvant treatment for metastatic colorectal cancer. Objectives: We aimed to evaluate the efficacy and toxicity of bevacizumab plus chemotherapy compared with bevacizumab-naive based chemotherapy as second-line treatment in people with metastatic CRC. Methods: Electronic databases were searched for eligible studies updated to March 2018. Randomized-controlled trials comparing addition of bevacizumab to chemotherapy without bevacizumab in MCRC patients were included, of which, the main interesting results were the efficacy and safety profiles of the addition of bevacizumab in patients with MCRC as second-line therapy. Result: Five trials were eligible in the meta-analysis. Patients who received the combined bevacizumab and chemotherapy treatment in MCRC as second-line therapy showed a longer overall survival (OS) (OR=0.80,95%CI=0.72-0.89, P<0.0001) and progression-free survival (PFS) (OR=0.69,95%CI=0.61-0.77, P<0.00001). In addition, there was no significant difference in objective response rate (ORR) (RR=1.36,95%CI=0.82-2.24, P=0.23) or severe adverse event (SAE) (RR=1.02,95%CI=0.88-1.19, P=0.78) between bevacizumab-based chemotherapy and bevacizumabnaive based chemotherapy. Conclusion: Our results suggest that the addition of bevacizumab to the chemotherapy therapy could be an efficient and safe treatment option for patients with metastatic colorectal cancer as second-line therapy and without increasing the risk of an adverse event.

Purpose Fluorouracil (FU)-leucovorin (LV), irinotecan, and oxaliplatin administered alone or in combination have proven effective in the treatment of advanced colorectal cancer (CRC). Combination protocols using FU-LV with either irinotecan or oxaliplatin are currently regarded as standard first-line therapies in this disease. However, the importance of the availability of all three active cytotoxic agents, FU-LV, irinotecan, and oxaliplatin, on overall survival (OS) has not yet been evaluated. Materials and Methods We analyzed data from seven recently published phase III trials in advanced CRC to correlate the percentage of patients receiving second-line therapy and the percentage of patients receiving all three agents with the reported median OS, using a weighted analysis. Results The reported median OS is significantly correlated with the percentage of patients who received all three drugs in the course of their disease (P = .0008) but not with the percentage of patients who received any second-line therapy (P = .19). In addition, the use of combination protocols as first-line therapy was associated with a significant improvement in median survival of 3.5 months (95% CI, 1.27 to 5.73 months; P = .0083). Conclusion Our results support the strategy of making these three active drugs available to all patients with advanced CRC who are candidates for such therapy to maximize OS. In addition, our findings suggest that, with the availability of effective salvage options, OS should no longer be regarded as the most appropriate end point by which to assess the efficacy of a palliative first-line treatment in CRC.

Abstract Background FOLFOXIRI plus bevacizumab is used as a first-line therapy for patients with unresectable or metastatic colorectal cancer. However, there are no clear recommendations for second-line therapy after FOLFOXIRI plus bevacizumab combination. Here, we describe our planning for the EFFORT study to investigate whether FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for mCRC. Methods EFFORT is an open-label, multicenter, single arm phase II study to evaluate whether a FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for mCRC. Patients with unresectable or metastatic colorectal cancer who received FOLFOXIRI plus bevacizumab as a first-line therapy will receive aflibercept and FOLFIRI (aflibercept 4 mg/kg, irinotecan 150 mg/m2 IV over 90 min, with levofolinate 200 mg/m2 IV over 2 h, followed by fluorouracil 400 mg/m2 bolus and fluorouracil 2400 mg/m2 continuous infusion over 46 h) every 2 weeks on day 1 of each cycle. The primary endpoint is progression-free survival (PFS). To achieve 80% power to show a significant response benefit with a one-sided alpha level of 0.10, assuming a threshold progression-free survival of 3 months and an expected value of at least 5.4 months, we estimated that 32 patients are necessary. Secondary endpoints include overall survival, overall response rate, safety, and exploratory biomarker analysis for differentiating anti-VEGF drug in 2nd-line chemotherapy for unresectable or metastatic colorectal cancer. Discussion This is the first study to investigate whether FOLFIRI plus aflibercept has efficacy following FOLFOXIRI plus bevacizumab for unresectable or metastatic colorectal cancer. Switching to a different type of anti-VEGF drug in second-line therapy after FOLFOXIRI plus bevacizumab appears to be an attractive treatment strategy when considering survival benefit. It is expected that this phase II study will prove the efficacy of this strategy and that a biomarker for drug selection will be discovered.

PURPOSE AND METHODS: For more than three decades, the therapeutic options for patients with advanced colorectal cancer have almost exclusively been based on fluoropyrimidines. With the recognition that topoisomerase-I (TOP-I) is an important therapeutic target in cancer therapy, irinotecan, a semisynthetic TOP-I–interactive camptothecin derivative, has been clinically established in the treatment of colorectal cancer. RESULTS: Irinotecan was investigated as second-line chemotherapy after prior treatment with fluorouracil (FU)-based regimens in two large randomized phase III trials comparing irinotecan with either best supportive care or an infusional FU/leucovorin (LV) regimen. The outcomes of these trials established irinotecan as the standard therapy in the second-line treatment of colorectal cancer. The therapeutic value of irinotecan in the first-line treatment of metastatic colorectal cancer was investigated in two large randomized phase III trials comparing the combination of irinotecan and FU/LV with FU/LV alone. Both trials demonstrated significant superior efficacy for the combination of irinotecan and FU/LV in terms of response rate, median time to disease progression, and median survival time. Consequently, the combination of irinotecan and FU/LV has been approved as first-line chemotherapy for patients with metastatic colorectal cancer and constitutes the reference therapy against which other treatment options must be tested in the future. CONCLUSION: In this review, the clinical rationale and update of the present clinical status of irinotecan in the treatment of colorectal cancer and future prospects of irinotecan-based combinations are discussed.
