Oxaliplatin is a standard first-line treatment for metastatic colorectal cancer. The objectives were to document the therapeutic management of oxaliplatin in South Africa, determine the incidence and severity of sensory neuropathy, and record the 2-year survival rate. Meccelox was a prospective, noncontrolled, open label, multicentre, observational survey of adult patients with stage IV metastatic colorectal cancer treated with oxaliplatin-based chemotherapeutic regimens. The study was conducted from August 2007 to November 2011 in 29 sites in South Africa by 66 participating treating physicians. Among the 195 enrolled patients, 61% were treated with FOLFOX regimen (5-fluorouracil/folinic acid plus oxaliplatin) for an average of 12 cycles and 32% patients were treated with XELOX (capecitabine plus oxaliplatin) for an average of 6–8 cycles, with the main reason for discontinuation being completion of the preplanned prescribed regimen. In Meccelox survey, 80% of patients were treated with intent of palliation. Overall 64% of patients reported symptoms of sensory neuropathy. The 2-year survival rate was 30%. Conclusions. Patients received a specified preplanned number of chemotherapy cycles rather than being treated until disease progression or toxicity. Both the incidence of neuropathy and the 2-year survival rate were less than previous reports.

PURPOSE: To study how adding oxaliplatin (l-OHP) to chronomodulated fluorouracil (5-FU)–leucovorin (LV) affected the objective response rate, as first-line treatment of metastatic colorectal cancer. PATIENTS AND METHODS: Two hundred patients from 15 institutions in four countries were randomly assigned to receive a 5-day course of chronomodulated 5-FU and LV (700 and 300 mg/m2/d, respectively; peak delivery rate at 0400 hours) with or without l-OHP on the first day of each course (125 mg/m2, as a 6-hour infusion). Each course was repeated every 21 days. Response was assessed by extramural review of computed tomography scans. RESULTS: Grade 3 to 4 toxicity from 5-FU–LV occurred in ≤ 5% of the patients (≤ 1% of the courses). Grade 3 to 4 diarrhea occurred in 43% of the patients given l-OHP (10% of the courses), and less than 2% of the patients had severe hematotoxicity. Thirteen percent of the patients had moderate functional impairment from peripheral sensory neuropathy. Sixteen percent of the patients receiving 5-FU–LV had an objective response (95% confidence interval [CI], 9% to 24%), compared with 53% of those receiving additional l-OHP (95% CI, 42% to 63%) (P < .001). The median progression-free survival time was 6.1 months with 5-FU–LV (range, 4.1 to 7.4 months) and 8.7 months (7.4 to 9.2 months) with l-OHP and 5-FU–LV (P = .048). Median survival times were 19.9 and 19.4 months, respectively. CONCLUSION: By chronomodulating 5-FU–LV, we were able to add l-OHP without compromising dose-intensities. l-OHP significantly improved the antitumor efficacy of this regimen.

TPS268 Background: 5-fluorouracil (5FU), in combination with folates, is an established cornerstone of metastatic colorectal cancer (mCRC) treatment. All folates currently approved for mCRC need to be metabolically activated to [6R]-5,10-methylenetetrahydrofolic acid ([6R]-MTHF), the active thymidylate synthase co-substrate that potentiates the effect of 5FU. Arfolitixorin does not require multi-step metabolic activation, and may produce higher, and less inter- and intraindividually variable, concentrations of [6R]-MTHF than leucovorin. Methods: The phase III AGENT trial (NCT03750786) is a randomized, multicenter, parallel-group study comparing the efficacy of arfolitixorin versus leucovorin in mCRC patients treated with first-line 5FU, oxaliplatin, and bevacizumab. Patients are randomized (1:1) to the investigational arm (arfolitixorin + 5FU + oxaliplatin [ARFOX] + bevacizumab) or the comparator arm (leucovorin + 5FU + oxaliplatin [modified FOLFOX-6] + bevacizumab), and treated until disease progression based on RECIST 1.1 criteria. Recruitment is ongoing, and aims to randomize 440 patients in 18 months. Eligibility criteria include non-resectable mCRC; eligibility for 5FU, oxaliplatin, and bevacizumab therapy; ECOG PS 0 or 1. The study will be conducted across approximately 100 sites in Australia, Austria, Canada, France, Germany, Greece, Japan, Spain, Sweden, and USA. The primary endpoint is objective response rate. Key secondary endpoints are progression-free survival and duration of response. Additional secondary endpoints include overall survival, quality of life, safety and tolerability, and number of patients undergoing curative metastasis resection. A translational program will evaluate expression levels of several folate metabolism- and transportation-related genes in mCRC tumor biopsies to determine their relationship to treatment outcome. A broad array of genes will analyzed, including ATP-binding cassette C3 (ABCC3) transporter, methylenetetrahydrofolate dehydrogenase 2 (MTHFD2), proton-coupled folate transporter (PCFT), and serine hydroxymethyltransferase 1 (SHMT1). Interim data are expected in mid 2020. Clinical trial information: NCT03750786.

This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of bevacizumab in combination with fluoropyrimidine-based chemotherapy for the first-line treatment of metastatic colorectal cancer based on the manufacturer’s submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. Evidence was available in the form of one phase III, multicentre, multinational, randomised, open-label study (NO16966 trial). This two-arm study was originally designed to demonstrate the non-inferiority of oral capecitabine plus oxaliplatin (XELOX) compared with 5-fluorouracil plus folinic acid plus oxaliplatin (FOLFOX)-4 in adult patients with histologically confirmed metastatic colorectal cancer who had not previously been treated. Following randomisation of 634 patients, the open-label study was amended to include a 2 × 2 factorial randomised (partially blinded for bevacizumab) phase III trial with the coprimary objective of demonstrating superiority of bevacizumab in combination with chemotherapy compared with chemotherapy alone. Measured outcomes included overall survival, progression-free survival, response rate, adverse effects of treatment and health-related quality of life. The manufacturer’s primary pooled analysis of superiority (using the intention-to-treat population) showed that after a median follow-up of 28 months, the addition of bevacizumab to chemotherapy significantly improved progression-free survival and overall survival compared with chemotherapy alone in adult patients with histologically confirmed metastatic colorectal cancer who were not previously treated [median progression-free survival 9.4 vs 7.7 months (absolute difference 1.7 months); hazard ratio (HR) 0.79, 97.5% confidence interval (CI) 0.72 to 0.87; p = 0.0001; median overall survival 21.2 vs 18.9 months (absolute difference 2.3 months); HR 0.83, 97.5% CI 0.74 to 0.93; p = 0.0019]. The NO16966 trial was of reasonable methodological quality and demonstrated a significant improvement in both progression-free survival and overall survival when bevacizumab was added to XELOX or FOLFOX. However, the size of the actual treatment effect of bevacizumab is uncertain. The ERG believed that the modelling structure employed was appropriate, but highlighted several key issues and areas of uncertainty. At the time of writing, NICE was yet to issue the guidance for this appraisal.

Efficacy Criteria

Introduction. Trifluridine/Tipiracil (FTD/TPI) is a new chemotherapeutic drug approved in more than 60 countries for use in patients with metastatic colorectal cancer who have registered progression or intolerance to treatment with fluoropyrimidines, oxaliplatin and irinotecan, anti-VEGRand anti-EGFR-targeted agents. This study evaluated for the first time the effectiveness and tolerability of FTD/TPI therapy in the Russian patient population.Materials and methods. A confirmatory open-label single-arm non-randomized trial was conducted in 2 clinical centres in Russia. The main criteria for inclusion were: conduction of at least the 2nd line of standard systemic therapy for metastatic colon adenocarcinoma. The primary efficacy criteria were: 2-month progression-free survival; secondary – median progressionfree survival, disease control frequency, safety assessment, overall survival. Research number: NCT03274882.Results. A total of 26 patients were included in the study; the median age was 60.5 years (30 to 78); 19 (73%) women; and 4 patients with ECOG 0 and 22 – with ECOG 1. All patients were previously treated with the inclusion of oxaliplatin, irinotecan, fluoropyrimidines, 21 (81%) – bevacizumab, 6 (23%) – anti-EGFR antibodies, and 2 (7.7%) – regorafenib. The median for treatment courses was 4 (1–21), 11 (42.3%) patients were treated for 6 months or more. The two-month progression-free survival rate was 52% with a median progreesion-free survival rate of 4 months (95% CI 1.8–7.4 months). The median of total survival rate was 11 months (95% CI 5,2–16,8 months). Disease control was achieved in 60%. Neutropenia, nausea, vomiting, anemia, weakness prevailed among undesirable events associated with treatment (≥5 patients). The majority of complications were of the 1st–2nd degree. Among the undesirable events of the 3rd–4th degree, neutropenia was more common, while in 3 patients febrile neutropenia of the 3rd degree was registered.Conclusions. In the Russian population of patients with colorectal chemorefractory cancer, the drug FTD/TPI (TAS-102) shows efficacy and tolerability comparable to the RECOURSE registration study.
