817 Background: The efficacy of the standard FOLFIRI-aflibercept second-line therapy may be improved by the chemotherapy regimen in metastatic colorectal cancer (MCRC). FOLFIRI was optimized by splitting the dose of irinotecan on day 1 and day 3 and by removing the bolus of 5-FU in the FOLFIRI3 regimen. Methods: This is a retrospective multicentric cohort, evaluating efficacy and safety of the association of aflibercept with FOLFIRI3, in patients (pts) with previously treated MCRC. The primary endpoint was overall response rate (ORR). Secondary endpoints were disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. Results: From September 2014 to December 2016, 74 pts were treated in four French centers. Nine pts were excluded due to prior use of aflibercept (n = 3), more than one prior line of treatment in irinotecan-naïve pts (n = 3) and inadequate liver function (n = 3). In the cohort of irinotecan-naïve pts (n = 30), ORR and DCR were 43.3% and 76.7%. Median PFS and OS were 11.3 months (95% CI 6.1-29.0) and 17.0 months (95% CI 13.0-17.3). The most common ( > 5%) grade 3-4 adverse events were diarrhea (37.9%), neutropenia (14.3%), stomatitis and anemia (10.4%), hypertension (6.7%). In the cohort of pts previously treated with irinotecan (n = 35), 20 (57.1%) pts received ≥2 prior lines of treatment with various prior irinotecan regimen (FOLFIRINOX, n = 21; FOLFIRI, n = 10; FOLFIRI3, n = 4). ORR and DCR were 34.3% and 60.0%. Median PFS and OS were 5.7 months (95% CI 3.9-10.4) and 14.3 months (95% CI 12.8-19.5). In 4 patients refractory to irinotecan, FOLFIRI3-aflibercept led to one partial response, 2 stabilizations, and one patient not evaluable. Conclusions: A minimal modification of the FOLFIRI regimen led to a dramatically improvement of efficacy with FOLFIRI3-aflibercept, whatever prior use of irinotecan. Further randomized trial is planned.

642 Background: Panitumumab and cetuximab are known to be effective in KRAS wild-type metastatic colorectal cancer (mCRC). However, it is not clear whether panitumumab and irinotecan confers benefit that are comparable to those of cetuximab and irinotecan in patients with KRAS wild-type mCRC previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based regimes. Methods: We analyzed 139 patients who had received panitumumab or cetuximabu combined with irinotecan for KRAS wild-type mCRC previously treated with fluor opyrimidine-, oxaliplatin-, and irinotecan-based regimes.We evaluated and compared efficacy and safety of panitumumab plus irinotecan and cetuximab plus irinotecan. Results: Baseline characteristics were similar for the two groups receving cetuximab pulus irinotecan (n = 97) and panitumumab plus irinotecan (n = 42),respectively.In patients with measurable lesions,the response rate (unconfirmed complete or partial response) were 20% (18/92) in the group receving cetuximab plus irintecan and 34% (14/41) in that receving panitumumab plus irinotecan. Median progression-free survival was 5.7 months in the cetuximab plus irinotecan group versus 4.3 months in the panitumumab plus irinotecan group. Median overall survival was 11.2 months in the cetuximab plus irinotecan group versus 13.6 months in the panitumumab plus irinotecan group. The most common adverse events in the cetuximab plus irinotecan versus panitumumab plus irinotecan groups were all-grade rash acneiform (82% versus 90%), paronychia (61% versus 52%), and grade 3-4 neutropenia (26% versus 19%). Conclusions: Panitumumab or cetuximab plus irinotecan were well tolerated and produced similar response rate and survivals compared to those previous clinical traials.These combinations are cosidered as standard treatment in patients with KRAS wild-type mCRC previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based regimes.

Purpose To investigate the combination of erlotinib, capecitabine, and oxaliplatin in patients who were previously treated for metastatic colorectal cancer. Patients and Methods Patients were eligible if they had metastatic colorectal cancer that progressed, were intolerant to first-line chemotherapy, or had disease recurrence within 1 year of adjuvant therapy for early-stage disease. Each 21-day cycle consisted of daily oral erlotinib at 150 mg, oral capecitabine at 1,000 mg/m2 (reduced to 750 mg/m2 after the first 13 patients) twice a day on days 1 to 14, and intravenous oxaliplatin at 130 mg/m2 on day 1. Results Thirty-two patients were enrolled onto this phase II study. By intention-to-treat analyses, eight patients (25%) experienced a partial response and 14 patients (44%) had stable disease for at least 12 weeks. The median progression-free survival was 5.4 months and the median overall survival was 14.7 months. These results were essentially unchanged when limited to the cohort of patients (78%) who received prior irinotecan for metastatic colorectal cancer. Most common grade 3 to 4 toxicities included diarrhea (38%), nausea/emesis (19%), fatigue (16%), dehydration (16%), and dermatitis (13%); grade 3 or 4 toxicities were reduced with a lower starting dose of capecitabine. Conclusion The combination of capecitabine, oxaliplatin, and erlotinib seems to have promising activity against metastatic colorectal cancer in patients who received prior chemotherapy, with a relatively higher response rate and progression-free survival compared with previous reports of either infusional FU, leucovorin, and oxaliplatin or capecitabine and oxaliplatin in similar patient populations.

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.

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 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.

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]

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.

Abstract Background: To date, there are few clinical studies comparing the efficacy and safety of FOLFIRI (folinic acid, fluorouracil and irinotecan) plus bevacizumab or aflibercept in metastatic colorectal cancer patients (mCRC) pretreated with oxaliplatin-based chemotherapy. Methods: We analyzed the treatment outcomes of patients receiving FOLFIRI in combination with bevacizumab or aflibercept as second-line treatment for mCRC between October 2017 and March 2020. This analysis included 67 patients receiving FOLFIRI plus aflibercept and 83 receiving FOLFIRI plus bevacizumab. Results: The overall response rate (ORR) was 13.6% (95% CI: 4.85-22.34) in the FOLFIRI-aflibercept group and 14.7% (95% CI: 6.68-22.71) in the FOLFIRI-bevacizumab group. This difference in ORR was not statistically significant. The median progression free survival (PFS) was 8.6 months in the FOLFIRI-bevacizumab group and 8.5 months in the FOLFIRI-aflibercept group (P = 0.752) (Fig. 1). Patients in the FOLFIRI-bevacizumab group showed a median overall survival (OS) of 12.4 months, while patients in the FOLFIRI-aflibercept group had a median OS of 13.7 months (P = 0.276). There were no significant differences in survival between the two treatment groups. The adverse events were also largely similar between the two groups. However, hypertension of grade 3 or more was more frequent in the FOLFIRI-aflibercept group. Conclusion: FOLFIRI plus bevacizumab and FOLFIRI plus aflibercept had similar anti-tumor activities and toxicity profiles when used as second-line therapy in mCRC patients. Based on these data, both aflibercept and bevacizumab are suitable anti-angiogenic agents when used in combination with FOLFIRI for mCRC.
