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.

The Impact

In the RECOURSE trial which lead to its accreditation, Lonsurf (trifluridine/tipiracil) was shown to extend progression free survival (PFS) by 1.8 months in metastatic colorectal cancer. This Trust audit aims to assess the average quantity of cycles of Lonsurf received by participants and the length of time it extends PFS. Similarly, to identify how many participants required a dose-reduction or experienced toxicities which necessitated supportive therapies. Quantitative data was collected retrospectively from all participants who had received ≥1 cycle of Lonsurf from The Clatterbridge Cancer Centre (CCC) from 2016 until June 2020. Participant electronic patient records were accessed to identify toxicity grading, length of treatment received, the date progression was identified, if dose reductions were applied and if supportive therapies were administered. Lonsurf extends PFS in patients with metastatic colorectal cancer at CCC by 3.0 months (95% CI: 2.73–3.27) and average treatment length was 2.4 months. However, 78 participants (41.5%) received a dose reduction due to toxicities. A total of 955 toxicities were recorded by participants; the most commonly reported toxicities irrespective of grade were fatigue (33.8%), diarrhoea (13.8%) and nausea (12.3%). The most common grade ≥3 toxicities were constipation and infection. The most frequently utilised supportive therapies were loperamide (49.6%) and domperidone (49.1%). Granulocyte colony stimulating factor (GCSF) was required by patients on 5 occasions (0.3%) in total. Lonsurf extends median PFS in patients with metastatic colorectal cancer by 3.0 months. The most common grade ≥3 toxicities which necessitated supportive therapies or a dose reduction were gastrointestinal and infection.

e15066 Background: The FOLFOX regimen consisting of fluorouracil (5-FU) and oxaliplatin, and the FOLFIRI regimen consisting of 5-FU and irinotecan serve as either first- or second-line treatment for metastatic colorectal cancer (mCRC), and there is no third-line chemotherapy regimen after failure of 5-FU, oxaliplatin, and irinotecan. Studies have shown that raltitrexed or S-1 has no complete cross-resistance with 5-FU and may be used for mCRC after failure of 5-FU. In the present study, we retrospectively analyzed the efficacy and safety of raltitrexed combined with S-1 in the treatment of mCRC after failure of conventional chemotherapy. Methods: Eighteen patients with mCRC treated with raltitrexed combined with S-1 after failure of fluorouracil, oxaliplatin and irinotecan between February 2014 and August 2016 were included in this study. Raltitrexed (3 mg/m2) intravenous infusion was given on the first day, and the administration of S-1 (daily dose according to body surface area (BSA): 100 mg/day when BSA ≥1.25 m2 to < 1.5 m2; 120 mg/day when BSA≥1.5 m2) continued for 2 weeks, and stopped for one week. The regimen was repeated every 3 weeks. Tumor response was evaluated according to RECIST 1.1 criteria. Toxicity was graded according to NCI-CTC 4.0 version. Results: Among 18 patients, 2 had PR, 8 had SD, and 8 had PD. The ORR (objective response rate) was 11.1%, and the DCR (disease control rate) was 55.6%. The median PFS (progression free survival) and OS (overall survival) were 2.5 months and 7.0 months respectively. Adverse reactions included fatigue, abnormal liver enzymes, neutropenia, stomatitis, pyrexia, arrhythmia, hypertension, diarrhea, nausea and most of these were grade 1-2. Only one patient had grade 3 neutropenia and grade 3 diarrhea. Conclusions: The combination of raltitrexed and S-1, both of which targeting TS, preliminarily showed promising effects for metastatic colorectal cancer after failure of standard chemotherapyand may be used as third-line treatment regimen.

467 Background: Patients with CCA usually present with advanced disease leading to the grave prognosis. Currently, cisplatin and gemcitabine is the standard treatment in advanced CCA. However, the CCA treatment outcomes are still poor and the options of treatment are quite limited. This study aimed to explore the efficacy and safety of S-1 plus leucovorin in patients with untreated advanced CCA. Methods: This single-arm two-center phase 2 study evaluated the efficacy and safety of S-1 40, 50 and 60 mg according to body surface area and leucovorin 15 mg , both given orally twice daily for one week, repeated every two weeks. Treatment was continued until complete 12 cycles, disease progression or unacceptable toxicity. The primary endpoints were overall response rate (ORR) and disease control rate (DCR) per RECIST version 1.1. The secondary endpoints were progression free survival (PFS), overall survival (OS) and toxicity. Results: Of total 32 patients and a median follow up time of 9.5 months, the ORR was 25% (95%CI 9.1-40.9) and the DCR was 62.5% (95% CI 44.8-80.2). In 25 response evaluable patients, the ORR was 32% (95% CI 12.4-51.7). The PFS was 8.0 (95%CI 5.59-10.4) months. The OS was 11.0 (95%CI 9.47-12.53). The most common grade 3 or 4 toxicities were anemia, mucositis and diarrhea. There was one patient discontinuing treatment due to treatment related toxicity. Conclusions: S-1 plus leucovorin was active and tolerable in patients with advanced CCA. Clinical trial information: TCTR20160313001.

Aim: We report real-world evidence with regorafenib in previously treated metastatic colorectal cancer from the French cohort of the international, prospective, observational CORRELATE study. Patients & methods: Patients receiving regorafenib according to French health authority approval were included. The primary end point was treatment-emergent adverse events. Overall survival and progression-free survival were secondary end points. Results: Two hundred and forty-two patients (61% male, median age: 66 years) were enrolled. The most common grade ≥3 drug-related treatment-emergent adverse events were hand–foot skin reaction (10.3%), asthenia/fatigue (9.9/1.2%) and hypertension (6.2%). Median overall survival and progression-free survival were 6.8 (95% CI: 6.3–7.6) and 2.8 months (95% CI: 2.6–3.0), respectively. Conclusion: The real-world safety and effectiveness data of regorafenib in metastatic colorectal cancer in France align with findings from Phase III clinical trials and the global CORRELATE population.

Real World Data

In the UK, Trifluridine-tipiracil (Lonsurf) is used to treat metastatic colorectal cancer in the third-line setting, after prior exposure to fluoropyrimidine-based regimes. Current data on the real-world use of Lonsurf lack long-term follow-up data. A retrospective evaluation of patients receiving Lonsurf at our Cancer Centre in 2016–2017 was performed, all with a minimum of two-year follow-up. Fifty-six patients were included in the review. The median number of cycles of Lonsurf administered was 3. Median follow-up was 6.0 months, with all patients deceased at the time of analysis. Median progression-free survival (PFS) was 3.2 months, and overall survival (OS) was 5.8 months. The median interval from Lonsurf discontinuation to death was two months, but seven patients received further systemic treatment and median OS gained was 12 months. Lonsurf offered a slightly better PFS but inferior OS to that of the RECOURSE trial, with PFS similar to real-world data previously presented. Interestingly, 12.5% had a PFS > 9 months, and this cohort had primarily left-sided and RAS wild-type disease. A subset received further systemic treatment on Lonsurf discontinuation with good additional OS benefit. Lonsurf may alter the course of disease for a subset of patients, and further treatment on progression can be considered in carefully selected patients.

This study aimed to investigate the efficacy and safety of systemic therapies in the treatment of unresectable advanced or metastatic colorectal cancer. Predicted hazard ratios (HRs) and their 95% credible intervals (CrIs) for overall survival (OS) were calculated from the odds ratio (OR) for the overall response rate and/or HR for progression-free survival using multivariate random effects (MVRE) models. We performed a network meta-analysis (NMA) of 49 articles to compare the efficacy and safety of FOLFOX/FOLFIRI±bevacizumab (Bmab)/cetuximab (Cmab)/panitumumab (Pmab), and FOLFOXIRI/CAPEOX±Bmab. The NMA showed significant OS improvement with FOLFOX, FOLFOX+Cmab, and FOLFIRI+Cmab compared with that of FOLFIRI (HR = 0.84, 95% CrI = 0.73–0.98; HR = 0.76, 95% CrI = 0.62–0.94; HR = 0.80, 95% CrI = 0.66–0.96, respectively), as well as with FOLFOX+Cmab and FOLFIRI+Cmab compared with that of FOLFOXIRI (HR = 0.69, 95% CrI = 0.51–0.94 and HR = 0.73, 95% CrI = 0.54–0.97, respectively). The odds of adverse events grade ≥3 were significantly higher for FOLFOX+Cmab vs. FOLFIRI+Bmab (OR = 2.34, 95% CrI = 1.01–4.66). Higher odds of events were observed for FOLFIRI+Pmab in comparison with FOLFIRI (OR = 2.16, 95% CrI = 1.09–3.84) and FOLFIRI+Bmab (OR = 3.14, 95% CrI = 1.51–5.89). FOLFOX+Cmab and FOLFIRI+Bmab showed high probabilities of being first- and second-line treatments in terms of the efficacy and safety, respectively. The findings of the efficacy and safety comparisons may support the selection of appropriate treatments in clinical practice. PROSPERO registration: CRD42020153640.

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.

Purpose The aim was to investigate whether germline polymorphisms within candidate genes known or suspected to be involved in fluorouracil (FU), oxaliplatin, and irinotecan pathways were associated with toxicity and clinical outcome in patients with metastatic colorectal cancer (mCRC). Patients and Methods Blood samples from 349 patients included in the Fédération Francophone de Cancérologie Digestive 2000-05 randomized trial, which compared FU plus leucovorin (LV5FU2) followed by FU, leucovorin, and oxaliplatin (FOLFOX) followed by FU, leucovorin, and irinotecan (FOLFIRI; sequential arm) with FOLFOX followed by FOLFIRI (combination arm) in terms of progression-free survival (PFS) and overall survival, were collected. Twenty polymorphisms within the DPD, TS, MTHFR, ERCC1, ERCC2, GSTP1, GSTM1, GSTT1, and UGT1A1 genes were genotyped. Results The ERCC2-K751QC allele was independently associated with an increased risk of FOLFOX-induced grade 3 or 4 hematologic toxicity (P = .01). In the sequential arm, TS-5′UTR3RG and GSTT1 alleles were independently associated with response to LV5FU2 (P = .009) and FOLFOX (P = .01), respectively. The effect of oxaliplatin on tumor response increased with the number of MTHFR-1298C alleles (test for trend, P = .008). The PFS benefit from first-line FOLFOX was restricted to patients with 2R/2R (hazard ratio [HR] = 0.39; 95% CI, 0.23 to 0.68) or 2R/3R (HR = 0.59; 95% CI, 0.42 to 0.82) TS-5′UTR genotypes, respectively. Conversely, patients with the TS-5′UTR 3R/3R genotype did not seem to benefit from the adjunction of oxaliplatin (HR = 0.96; 95% CI, 0.66 to 1.40; trend between the three HRs, P = .006). Conclusion A pharmacogenetic approach may be a useful strategy for personalizing and optimizing chemotherapy in mCRC patients and deserves confirmation in additional prospective studies.

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.

Clinical Trial Information

775 Background: TAS-102 is comprised of an antineoplastic thymidine-based nucleoside analog, trifluridine (FTD), and a thymidine phosphorylase inhibitor, tipiracil. Primary results of the RECOURSE trial demonstrated a significant improvement in overall survival (OS) and progression-free survival (PFS) with TAS-102 vs placebo (pbo) in patients (pts) with metastatic colorectal cancer refractory/intolerant to standard therapies. Neutropenia is a common TAS-102–associated adverse event and it has been hypothesized to be associated with a relatively high FTD concentration in pts. Methods: RECOURSE data were analyzed post hoc for correlations between onset of neutropenia (Grade 3/4) and survival benefit. Results: Of 533 pts given TAS-102, 75 (14%) developed Grade 3/4 neutropenia in treatment cycle 1, 86 (16%) for the first time in cycle 2, and 39 (7%) for the first time in cycle ≥3. Onset of neutropenia at any cycle was associated with longer median OS and PFS compared with no neutropenia. A consistent survival benefit was observed regardless of the cycle of initial onset of neutropenia, as demonstrated by the hazard ratio (against cycle-matched pbo control groups) and corresponding median OS differences (Table). Conclusions: An association between occurrence of earliest onset of Grade 3/4 neutropenia and survival benefit was observed. The data indicate that such survival benefit occurred regardless of whether the initial onset of neutropenia occurred after cycle 1, cycle 2, or later. Further analyses are required to fully determine whether FTD pharmacokinetics correlate with TAS-102 efficacy and onset of neutropenia, and whether cycle initiation delays affect response. Clinical trial information: NCT01607957. [Table: see text]
