3006 Background: Single agent PD-1/L1 inhibition are not effective in metastatic colorectal cancer (MCRC) with microsatellite stable tumors. However, signal of efficacy was shown using combo therapy of anti-PD-L1 and anti CTLA-4 in multitreated patients. FOLFOX regimen could induced immunogenic cell death and elimination of myeloid derived suppressor cells (MDSCs) thus leading to a potential positive effect on antitumor immune response. Methods: This is a single arm exploratory investigator-initiated trial planned to include 57 pts to receive mFOLFOX6 (6cycles) in combination with durvalumab (150mg/q2W) and tremelimumab (75mg/q4W). After 6 cycles of chemotherapy, patients are treated with durvalumab untils progression. Primary endpoint is 6 months’ progression-free survival rate. Secondary endpoints are response rate, tolerability and translational research evaluating tissue and blood immune parameter. Upon Simon’s design an efficacy intermediate analysis was planned after the 16th patient has passed 6 months. Results: As of 1st of January 2020 the 55/57 pts were enrolled and treated with the MEDETREME regimen at 8 French sites. The intermediate efficacy analysis was conducted on the 1st of January after a median of 13.4 months of treatment. The following adverse events were noted: asthenia (81.25%), neuropathy (87.5%), diarrhea (56.25%) and neutropenia (62.5%). Notable grade 3/4 (CTC AE 4.03) include asthenia (18.75%) diarrhea (12.5%) neutropenia (50%) and elevated blood pressure (25%). Most of adverse events were related to chemotherapy. It has been noted one cytolysis grade 3, one thyroid dysfunction grade 3 and one hypophysitis grade 3 related to immunotherapy. Median PFS was not reached. Progression free survival at 6 months was observed in 10/16 pts (62,5%) given 5 CR, 5 PR and 4 SD. Updated translational data will be presented at the meeting. Conclusions: The interim safety analysis has supported safety and efficacy of the MEDITREME regimen in first- line MCRC. Finally, results will be presented after maturation of follow up.

Abstract Background: This study aimed to evaluate in clinical practice the efficacy and safety of polyethylene glycol conjugated granulocyte colony-stimulating factor (PEG-G-CSF) for preventing neutropenia in metastatic colorectal cancer (mCRC) patients that received fluorouracil, leucovorin, oxaliplatin, and irinotecan (FOLFOXIRI) plus bevacizumab (Bev). Methods: We retrospectively analyzed mCRC patients who received FOLFOXIRI plus Bev between December 2015 and December 2017. We evaluated the efficacy of PEG-G-CSF for treating neutropenia, the overall response rate (ORR) according to the Response Evaluation Criteria in Solid Tumors version 1.1, progression free survival (PFS), overall survival (OS), and adverse events of FOLFOXIRI plus Bev based on the Common Terminology Criteria for Adverse Events version 4.0. Results: A total of 26 patients (median age 53.5 years) were included. The ORR rate was 65.3%, the median PFS was 9.6 months (7.2–16.9), and the median OS was 24.2 months (13.6–NA). Grade 3 or 4 neutropenia occurred in 53.8% of the patients and febrile neutropenia occurred in 7.7%. PEG-G-CSF was given to 77.0% of the patients, including prophylactically (n = 9) and after the development of grade 3 or 4 neutropenia (n = 11). No patients experienced grade 3 or higher neutropenia after the administration of PEG-G-CSF. In seven of the nine patients who received PEG-G-CSF prophylactically (77.7%), no dose adjustment was required.Conclusions: PEG-G-CSF was useful in preventing severe neutropenia in mCRC patients treated with FOLFOXIRI plus Bev.

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.

614 Background: TAS-102 improved overall survival of metastatic colorectal cancer (mCRC) patients with median progression free survival (PFS) of 2.0 months (RECOURSE trial). Subsequently, the combination of TAS-102 and bevacizumab has been shown to extend median PFS with 3.7 months (C-TASK FORCE). However, this study included patients with 2nd line and 3rd line chemotherapy. Our study was planned exclusively for patients receiving this combination as a 3rd line chemotherapy to investigate clinical impact of this combination beyond cytotoxic doublet. Methods: This phase II study was conducted in investigator-initiated, open-label, single-arm, multicentered manner in Japan. Eligible patients were 20-80 years old, and had to have an ECOG performance status of 0 or 1; had confirmed unresectable mCRC with histologically diagnosed adenocarcinoma; were refractory or intolerant to fluoropyrimidine, irinotecan, and oxaliplatin in the 1st and the 2nd line chemotherapy. TAS-102 (35 mg/ m²) was given orally twice daily on days 1–5 and 8–12 in a 4-weeks cycle, and bevacizumab (5 mg/ kg) was administered by intravenous infusion for 30 minutes in every 2 weeks. The primary endpoint was progression free survival (PFS), and the secondary endpoints were time to treatment failure (TTF), response rate (RR), overall survival (OS), and safety. Results: Between June 2016 and August 2017, 32 pts were enrolled. The median PFS was 4.5 months, and the median OS was 9.3 months. Partial response was observed in 2 patients. The most common adverse events above grade 3 were neutropenia (15 patients) followed by thrombocytopenia (4 patients). Treatment-related serious adverse events were reported in 1 patient. There were no non-hematologic adverse events above grade 3. No treatment-related deaths occurred. Conclusions: This is the first study which involves the combination TAS-102 and bevacizumab as the 3rd line chemotherapy in the setting beyond cytotoxic doublet for the patients with mCRC. This study met its primary endpoint PFS, which is comparable to the results of C-TASK FORCE study. This combination has a potential to be one of therapeutic options of the 3rd line chemotherapy for mCRC. Clinical trial information: 000022438.

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.

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.

630 Background: Reintroduction of oxaliplatin seems to have clinical benefits for patients with metastatic colorectal cancer refractory to standard chemotherapy regimens. A interim analysis of RE-OPEN study reported 38.9% of disease control rate (DCR) in ASCO GI 2013, but it is still unknown who will receive benefits from reintroduction of oxaliplatin. Methods: Among patients in whom oxaliplatin was reintroduced in the 7 participating hospitals, we retrospectively studied patients who had previously received oxaliplatin and irinotecan and patients who had a response of stable disease or better during initial treatment with oxaliplatin. Results: From June 2009 through January 2013, oxaliplatin was reintroduced in 53 patients (31 men and 22 women). The median age was 64 years, and the performance status was 0 in 24 patients and 1 in 29. The reasons for discontinuing initial treatment with oxaliplatin were progressive disease in 36 patients, adverse events in 14 and others in 3. The response rate (RR), DCR, the median progression-free survival (PFS), and the median overall survival were 3.8%, 47.2%, 105 days, and 313 days, respectively. As for adverse events, allergic reactions to oxaliplatin (grade 1 or higher) occurred in 26% of the patients. RR, DCR, and PFS in 44 patients with the oxaliplatin-free-interval (OFI) over 6 months were 4.6%, 54.6%, and 119 days, respectively, and were statistically better than those in 9 patients with OFI less than 6 months (0%, 11.1%, and 84 days). Reintroduction of oxaliplatin with bevacizumab showed better PFS than that without bevacizumab (114 days and 78 days, respectively). Conclusions: Reintroduction of oxaliplatin was suggested to be one option for the management of colorectal cancer that is resistant to standard therapy, especially in patients with OFI over 6 months. Bevacizumab may enhance the results of reintroduction treatment.

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]

e15008 Background: To assess the safety and efficacy of apatinib, an oral vascular endothelial growth factor receptor-2 inhibitor, combined with thymidylate synthase inhibitor raltitrexed in patients with metastatic colorectal cancer (mCRC) as a third- or later-line therapy. Methods: Patients with mCRC after at least 2 lines of chemotherapy were enrolled whenever they previously treated with bevacizumab or not. Apatinib was given orally at 250mg or 500mg daily. Raltitrexed was administered intravenously at 3 mg/m2 on day 1 every 3 weeks. The primary endpoints were progression-free survival (PFS). The second endpoints were objective response rate (ORR), overall survival (OS) and safety. Results: From August 2017 to November 2018, thirty-one patients were enrolled in Chinese PLA General Hospital. After a median follow-up of 6.4 months, the median treatment cycle was 4. four patient achieved partial response(PR), and 11 patients achieved stable disease (SD) and 16 achieved progression disease (PD) in accordance with RECIST version 1.0, illustrating a DCR of 48.4% and an ORR of 12.9% .The Median PFS was 2.4 months and the median OS was 6.4 months. The most common adverse events were hypertension (n=12, 38.7%), nausea and vomiting (n=11, 33.8%), myelosuppression (n=9, 29.0%). The most common grade 3 to 4 adverse events were hypertension (n=2, 6.4%) and hand-foot syndrome (n=2, 6.4%). Grade 3 to 4 hematologic toxicities were rare. One patient died from cardiac arrest after three days treatment. There was no significantly association between PFS or OS, and clinical features including tumor location, KRAS status, and prior surgery or not, and number of metastatic organs. There was no trend showing patients who experienced had hypertension or myelosuppression had longer PFS and OS. Compared to the patients never received bevacizumab, the patients who had previously bevacizumab had the similar PFS and OS (3.9 versus 2.3months, P=0.787; 6.1 versus 6.4months, P=0.287). Grade1-2 nausea and vomiting and age <57 were independent predictors for longer PFS and OS. Conclusions: Apatinib combined with raltitrexed had efficacy but had limited survival benefit in mCRC refractory to standard chemotherapy. This regime showed us a higher risk of adverse event incidence and warrant further exploring of benefit population. Clinical trial information: NCT03344614 .

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.
