14555 Background: This is a phase II study combination of capecitabine plus bevacizumab for patients with metastatic colorectal cancer after failure of both irinotecan- and oxaliplatin-containing regimens. Methods: The dose of capecitabine was 1000 mg/m2, administered twice daily for 14 days every 3 weeks. Bevacizumab was given at a dose of 5mg/kg on day 1 as i.v. infusion every 3 weeks. Treatment was repeated until the occurrence of disease progression or unaccepted toxicity. Results: Twenty-eight patients were enrolled. Of 28 patients, the overall response rate was 14.3% and the disease control rate was 42.9%. With a median follow-up period of 7 months, median time to progression and overall survival duration were 3 months and 14 months, respectively. The 1-year survival rate of all patients was 60.7%. The most common treatment-related grade 3/4 hematological toxicities included leukopenia/neutropenia in 4 patients and thrombocytopenia in 3 patients. Nonhematologic toxicities attributable to bevacizumab included bleeding in 3 patients, hypertension in 4 patients, thromboses in 3 patients, proteinuria in 5 patients, and gastrointestinal perforation in 1 patient. Conclusions: This drug regimen was well tolerated and combination of bevacizumab and capecitabine shows potential as third line chemotherapy in heavily pretreated patients with metastatic colorectal cancer. No significant financial relationships to disclose.

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.

Background: Bevacizumab (BEV), a monoclonal antibody against vascular endothelial growth factor-A (VEGF-A), is a standard component of medical therapy of metastatic colorectal cancer (mCRC). Activation of alternative angiogenesis pathways has been implicated in resistance to BEV. This phase II study examines the activity of combined vertical blockade of VEGF signaling with sorafenib and BEV as salvage therapy in patients with progressive disease (PD) on all standard therapy in mCRC. Methods: mCRC patients with documented PD on standard therapy, received sorafenib (200 mg orally twice daily, days 1–5 and 8–12) and BEV (5 mg/kg intravenously, day 1) every 2 weeks. Primary endpoint was 3-month progression-free survival (PFS) rate and secondary endpoints were overall survival (OS), response rate (RR), safety, and feasibility. Results: Of the 83 patients enrolled, 79 were evaluable. Of these, 42 (53%) were progression-free at 3 months. Median PFS was 3.5 months and median OS was 8.3 months. One patient had a partial response and 50 patients (63.3%) had at least one stable tumor assessment. Of 79 evaluable patients, 54 (68%) experienced grade 3/4 adverse events (AEs) at least possibly related to treatment. Most frequent grade 3/4 AEs were: fatigue (24.1%), hypertension (16.5%), elevated lipase (8.9%), hand-foot skin reaction (8.9%), diarrhea (7.6%), and proteinuria (7.6%). Reasons for treatment discontinuation were PD (72%), AEs (18%), patient refusal (8%), physician decision (1%), and death (1%). Conclusions: The combination of BEV and sorafenib as salvage therapy in heavily pretreated mCRC patients is tolerable and manageable, with evidence of promising activity.

PURPOSE A phase II study to evaluate the response rate and toxicities of a trimetrexate, fluorouracil (5FU), and leucovorin regimen in patients with advanced incurable colorectal cancer. PATIENTS AND METHODS Thirty-six patients with unresectable or metastatic colorectal cancer who had not been treated for advanced disease received the following chemotherapy regimen weekly for six courses every 8 weeks: trimetrexate 110 mg/m2 intravenously (I.V.) on day 1, leucovorin 200 mg/m2 I.V. on day 2 (24 hours later), 5FU 500 mg/m2 on day 2 immediately following leucovorin, and oral leucovorin 15 mg every 6 hours for seven doses starting 6 hours after 5FU. Patients were treated until progression or unacceptable toxicity. RESULTS Thirty patients were assessable for response, and all 36 were assessable for toxicity. Two patients (7%) achieved a complete response (CR) and 13 (43%) a partial response (PR), for an overall response (OR) rate of 50% (95% confidence interval [CI], 32% to 68%). Analysis by intent to treat demonstrated a 42% OR rate (95% CI, 26% to 58%). At final analysis, 16 patients were alive. The median survival duration for the entire cohort was 53.4 weeks. Gastrointestinal toxicity was most common, with 21 patients (58%) having grade 3/4 diarrhea and 12 patients (34%) grade 3/4 nausea. Hematologic toxicity was generally low grade, although two patients died of sepsis. CONCLUSION The combination of trimetrexate with 5FU and leucovorin is active in metastatic colorectal cancer. Gastrointestinal toxicity with this regimen is most prominent, but is manageable.

e15584 Background: Options of therapy are limited for patients with colorectal cancer who developed disease progression during standard 5-FU-, oxaliplatin-, and irinotecan-contained regimens. There is straight information about synergy of irinotecan (SN-38) and oxaliplatin gained from fundamental and early clinical trials. We aimed to analyze effectiveness and safety of triple drug-combination of 5-FU, oxaliplatin and irinotecan (FOLFOXIRI) in heavily pretreated patients with metastatic colorectal cancer. Methods: Patients with a metastatic colorectal cancer who received more than 2 lines of standard 5-FU-, oxaliplatin- and irinotecan-based doublet regimens with or without targeted therapy were included. Reinduction of chemotherapy in previous lines was allowed. The retrospective analysis of medical histories was done. Eligible patients had to receive number of cycles that were sufficient for response rate estimation. Disease response was evaluated according to RECIST 1.1 criteria. Survival analysis was performed using the Kaplan-Meier method. Tolerability was estimated by CTCAE v. 5.0. Results: Forty-six patients were included in retrospective per protocol analysis. The median follow-up was 19 months. The median number of previous lines of chemotherapy was 2 (2-6). Primary resistance to oxaliplatin- and irinotecan-based chemo during previous lines was noted in 20 patients (43%) and 16 patients (35%), respectively, while seven patients (15%) developed the primary resistance to both agents given in a sequential order. All patients were treated with targeted therapy during previous treatment lines. The median of FOLFOXIRI cycles was 8 (range, 2-19). Two patients (4%) were treated with FOLFOXIRI without any targeted agents. The objective response rate was 33% (n = 15). The disease stabilization was reached in 43% (n = 20). The disease control rate was 76% (n = 35). Eleven patients (24%) had the progression of disease at the first follow-up. The median progression free survival and median overall survival were 6 months and 11 months, respectively. Toxicity was evaluated in 35 patients. The most common severe adverse events (grade 3 and 4) were neutropenia (46%) and fatigue (26%). Treatment was delayed in 20 patients (57%), and 13 patients (37%) required dose reduction. One patient had to discontinue treatment due to unacceptable toxicity. Conclusions: According to our study FOLFOXIRI provides the objective response and increased life expectancy in heavily pretreated patients. The further assessment of FOLFOXIRI regimen for refractory colorectal cancer in the prospective trials is needed.

<b><i>Background:</i></b> Due to few efficacious options in later lines of therapy in metastatic colorectal cancer (mCRC), there has been considerable interest in the possibility of retreatment with previously administered agents. This study investigated the efficacy and safety of irinotecan retreatment (IRI2) in patients with refractory mCRC. <b><i>Methods:</i></b> We performed a retrospective analysis of patients with mCRC who were retreated with irinotecan-based regimens. The retreatment regimens with anti-epidermal growth factor receptor therapies were excluded. <b><i>Results:</i></b> A total of 64 patients were included. Patients had a median age of 56 years and were offered mainly in the setting of third- or fourth-line therapy with IRI2. The disease control rate was 78.2% including an objective response of 23.5%. Median progression-free survival and overall survival were 5.5 and 19.3 months, respectively. The most frequent grade 3 or higher toxicities were nausea/vomiting (27.9%) and neutropenia (25%). <b><i>Conclusion:</i></b> IRI2 might be a reasonable option for heavily pretreated patients with mCRC who achieved disease control with prior irinotecan therapy.

57 Background: FOLFOXIRI plus bevacizumab (BEV) is regarded as the standard of care for selected patients (pts) with metastatic colorectal cancer (mCRC), despite the high incidence of neutropenia and diarrhea. The AXEPT phase III study showed that the modified capecitabine (CAP) + irinotecan (IRI) + BEV (CAPIRI+BEV) [CAP 1600 mg/m2, IRI 200 mg/m2, and BEV 7.5 mg/kg q3wk] treatment was non-inferior to FOLFIRI+BEV, with a lower incidence of hematologic toxicity. We hypothesized that the modified CAPIRI combined with oxaliplatin (OX) and BEV (CAPOXIRI+BEV) would be more feasible than FOLFOXIRI+BEV, without compromising efficacy. Methods: The QUATTRO-II study is an open-label, multicenter, randomized phase II study. In Step 1, the recommended doses (RD) of OX and IRI were investigated as a safety lead-in. In Step 2, pts are randomized to either the RD of CAPOXIRI+BEV or FOLFOXIRI+BEV. In Step 1, four dose levels of CAPOXIRI (fixed dose of CAP 1600 mg/m2 and BEV 7.5 mg/kg plus escalated or de-escalated doses of OX and IRI, q3wk) were investigated in a 3+3 manner. A dose level of ≤ 2/6 of dose-limiting toxicity (DLT) cases was expected as the RD. Results: A total of 9 pts (3 at Level 0, 6 at Level 1) were included in Step 1. The baseline characteristics were as follows: the median age was 62 years; 6 were male; 6 presented with a left-sided tumor; 8 had a performance status of 0; all wild type/ RAS mutant/ BRAF V600E mutant were 8/1/0; and UGT1A1 wild type/*6 single hetero/*28 single hetero were 7/0/2. In Level 0 (IRI 200 mg/m2, OX 100 mg/m2), one grade 4 neutropenia and one grade 3 anorexia were observed, but without DLT. In Level 1 (IRI 200 mg/m2, OX 130 mg/m2), two grade 4 neutropenia and one grade 3 colitis were observed, with 1 DLT (febrile neutropenia) case, fully recovered without G-CSF administration. No treatment-related deaths were observed. Although dose modifications were needed in 4 of the 6 pts, no further safety concerns related to treatment continuity were observed in the 2nd or subsequent cycles. Thus, we determined that the dose administered in Level 1 is the RD for Step 2. According to the preliminary efficacy results at 8 weeks after initiating study treatment, 6 pts achieved a partial response (2 in Level 0 and 4 in Level 1). Conclusions: The RD of CAPOXIRI+BEV was 200 mg/m2 IRI, 130 mg/m2 OX, 1600 mg/m2 CAP, and 7.5mg/kg BEV. The randomized phase II Step (Step 2) of QUATTRO-II is ongoing. Clinical trial information: NCT04097444.

PURPOSE To assess the efficacy of irinotecan (CPT-11) in the treatment of advanced colorectal cancer in both chemotherapy-naive and pretreated patients. PATIENTS AND METHODS Two hundred thirteen patients (aged 18 to 75 years) with metastatic colorectal cancer, World Health Organization (WHO) performance status < or = 2, and life expectancy > or = 3 months were treated with CPT-11 350 mg/m2 every 3 weeks. All 178 patients eligible for efficacy analysis had not received more than one prior fluorouracil (5-FU)-based chemotherapy regimen (adjuvant or palliative) and had adequate hematologic, renal, and hepatic function. RESULTS Primary tumor sites were the colon (71%) and rectum (28%). Sixty-six percent of the patients had > or = two metastatic sites. Ninety-eight percent of the patients had undergone previous surgery, and 77.5% had received prior chemotherapy. Thirty-two of 178 eligible patients achieved on objective response (four complete responses [CRs] and 28 partial responses [PRs]; response rate, 18%; 95% confidence interval, 12.6% to 24.4%), 65 were stable, and 59 progressed. The response rate was 17.7% in the pretreated group and 18.8% in the chemotherapy-naive group. Within the former subgroup, response rates of 16.1% were reported in patients who were progressive on prior 5-FU chemotherapy and 19.1% in patients who were progressive off such treatment. The median duration of objective response (9.1 months) and median time to achievement of a response (9.3 weeks) did not differ between chemotherapy-naive and pretreated patients. The most frequent adverse events were neutropenia, which developed in 80% of the patients, delayed diarrhea (87%), alopecia (88%), fatigue (81%), and nausea/vomiting (77%). All these adverse events were manageable. Severe (WHO grade 3 or 4) neutropenia was only observed in 18% of the cycles, leukopenia in 11%, delayed diarrhea in 11%, and nausea and vomiting in 3%. Development of simultaneous grade 3 or 4 neutropenia and delayed diarrhea during 4% of the cycles was the safety issue of greatest concern. CONCLUSION CPT-11 has definite activity in the treatment of advanced metastatic colorectal cancer both in chemotherapy-naive and in pretreated patients who experienced disease progression on 5-FU, which suggests a lack of cross-resistance between CPT-11 and 5-FU. Diarrhea and neutropenia, the major toxicities of CPT-11, contribute to the risk to develop febrile neutropenic sepsis.
