Project description:Trifluridine/tipiracil is approved for the use in later or last-line setting in previously treated metastatic colorectal cancer (mCRC) patients who progressed on standard anti-tumor drugs including 5-fluorouracil (5-FU), irinotecan, oxaliplatin, anti-VEGF and anti-EGFR antibodies, or who are not considered candidates for those standard therapies. In this report, we describe a 67-year-old male patient with KRAS-mutated mCRC and metachronous liver and lung metastasis who failed prior 5-FU- and irinotecan-containing regimens, but then showed long-term disease control for 31 months on single-agent trifluridine/tipiracil given as second-line treatment. According to our experience, trifluridine/tipiracil is a feasible and effective treatment option in earlier but not necessarily last-line therapy in mCRC patients who are not considered candidates for doublet or triplet chemotherapy. Besides its efficacy, it is associated with maintained quality of life and a manageable toxicity profile. Considering increasing age of mCRC patients and their wish for maintaining an independent lifestyle, further research on the use of trifluridine/tipiracil in earlier lines of systemic mCRC therapy is warranted.

Project description:BackgroundTherapeutic options are limited in patients with unresectable metastatic colorectal cancer (mCRC) ineligible for intensive chemotherapy. The use of trifluridine/tipiracil plus bevacizumab (TT-B) in this setting was evaluated in the TASCO1 trial; here, we present the final overall survival (OS) results.MethodsTASCO1 was an open-label, non-comparative phase II trial. Patients (n = 153) were randomised 1:1 to TT-B (trifluridine/tipiracil 35 mg/m2 orally twice daily on days 1-5 and 8-12, and bevacizumab intravenously 5 mg/kg on days 1 and 15 of each 28-day cycle) or capecitabine plus bevacizumab (C-B; capecitabine, 1250 mg/m2 orally twice daily on days 1-14 and bevacizumab 7.5 mg/kg intravenously on day 1 of each 21-day cycle). Final OS was analysed when all patients had either died or withdrawn from the study. Adjusted multivariate regression was used to investigate the effects of pre-specified variables on OS.ResultsAt 1 September 2020, median OS was 22.3 months (95% CI: 18.0-23.7) with TT-B and 17.7 months (95% CI: 12.6-19.8) with C-B (adjusted HR 0.78; 95% CI: 0.55-1.10). No variables negatively affected OS with TT-B. Safety results were consistent with prior findings.ConclusionsTT-B is a promising therapeutic regimen in mCRC patients ineligible for intensive chemotherapy.Clinical trial informationNCT02743221 (clinicaltrials.gov).

Project description:BackgroundThe phase II J003 (N = 169) and phase III RECOURSE (N = 800) trials demonstrated a significant improvement in survival with trifluridine (FTD)/tipiracil (TPI) versus placebo in patients with refractory metastatic colorectal cancer. This post hoc analysis investigated pharmacokinetic data of FTD/TPI exposure and pharmacodynamic markers, such as chemotherapy-induced neutropenia (CIN) and clinical outcomes.Patients and methodsA total of 210 patients from RECOURSE were enrolled in this substudy. A limited sampling approach was used, with three pharmacokinetic samples drawn on day 12 of cycle 1. Patients were categorized as being above or below the median area under the plasma concentration-time curve (AUC) for FTD and TPI. We conducted a post hoc analysis using the entire RECOURSE population to determine the correlations between CIN and clinical outcome. We then carried out a similar analysis on the J003 trial to validate the results.ResultsIn the RECOURSE subset, patients in the high FTD AUC group had a significantly increased CIN risk. Analyses of the entire population demonstrated that FTD/TPI-treated patients with CIN of any grade in cycles 1 and 2 had significantly longer median overall survival (OS) and progression-free survival (PFS) than patients who did not develop CIN and patients in the placebo group. Patients who required an FTD/TPI treatment delay had increased OS and PFS versus those in the placebo group and those who did not develop CIN. Similar results were obtained in the J003 cohort.ConclusionsIn RECOURSE, patients with higher FTD drug exposure had an increased CIN risk. FTD/TPI-treated patients who developed CIN had improved OS and PFS versus those in the placebo group and those who did not develop CIN. Similar findings were reported in the J003 cohort, thus validating the RECOURSE results. The occurrence of CIN may be a useful predictor of treatment outcomes for FTD/TPI-treated patients.

Project description:Genomics has greatly improved how patients with cancer are being treated; however, clinical-grade genomic biomarkers for chemotherapies are currently lacking. Using whole-genome analysis of 37 patients with metastatic colorectal cancer (mCRC) treated with the chemotherapy trifluridine/tipiracil (FTD/TPI), we identified KRAS codon G12 (KRASG12) mutations as a potential biomarker of resistance. Next, we collected real-world data of 960 patients with mCRC receiving FTD/TPI and validated that KRASG12 mutations were significantly associated with poor survival, also in analyses restricted to the RAS/RAF mutant subgroup. We next analyzed the data of the global, double-blind, placebo-controlled, phase 3 RECOURSE trial (n = 800 patients) and found that KRASG12 mutations (n = 279) were predictive biomarkers for reduced overall survival (OS) benefit of FTD/TPI versus placebo (unadjusted interaction P = 0.0031, adjusted interaction P = 0.015). For patients with KRASG12 mutations in the RECOURSE trial, OS was not prolonged with FTD/TPI versus placebo (n = 279; hazard ratio (HR) = 0.97; 95% confidence interval (CI) = 0.73-1.20; P = 0.85). In contrast, patients with KRASG13 mutant tumors showed significantly improved OS with FTD/TPI versus placebo (n = 60; HR = 0.29; 95% CI = 0.15-0.55; P < 0.001). In isogenic cell lines and patient-derived organoids, KRASG12 mutations were associated with increased resistance to FTD-based genotoxicity. In conclusion, these data show that KRASG12 mutations are biomarkers for reduced OS benefit of FTD/TPI treatment, with potential implications for approximately 28% of patients with mCRC under consideration for treatment with FTD/TPI. Furthermore, our data suggest that genomics-based precision medicine may be possible for a subset of chemotherapies.

Project description:Regorafenib and trifluridine/tipiracil (TAS-102) are novel antitumor agents for patients with refractory metastatic colorectal cancer. However, it is unclear which patients may derive a survival benefit from these drugs in real-life clinical practice. We evaluated retrospectively the efficacy and safety of regorafenib and TAS-102 at a single institution between June 2013 and November 2015. Cox regression analysis was carried out to obtain predictive scores (the nearest integers of hazard ratio) for survival benefit. Forty-four patients treated with regorafenib or TAS-102 were included in the analysis; among them, 17 received crossover treatment. The median overall survival (OS) was 9.1 months for regorafenib and 9.3 months for TAS-102, and the corresponding values after crossover were 7.1 and 5.3 months, respectively. OS was not correlated to relative dose intensity, but was proportional to the total administered dose of each drug. Adverse events were tolerable even after crossover. We identified three variables as significant for prediction of OS with good discrimination (C-statistic=0.70): Poor Eastern Cooperative Oncology Group performance status, time since diagnosis of metastatic disease ?18 months, and previous chemotherapy continued ?2 months beyond progression were all predictors of poor OS. Regorafenib and TAS-102 can be recommended for patients with better performance status and slow progression of metastatic disease. Optimal survival benefit was provided by prompt administration of either drug after failure of previous chemotherapy, with flexible titration to the optimal dose for each individual patient.

Project description:BackgroundThe outcome of patients with refractory metastatic colorectal cancer (mCRC) treated with trifluridine/tipiracil (FTD/TPI) beyond the second-line has not been studied in Saudi Arabia. Therefore, this multicenter retrospective analysis was conducted to evaluate the efficacy of FTD/TPI.MethodsThis multicenter retrospective analysis included five centers in Saudi Arabia. FTD/TPI was administered to all the patients beyond the oxaliplatin- and irinotecan-based chemotherapy regimens. The electronic medical records were reviewed, and progression-free survival (PFS) and overall survival (OS) were determined.ResultsThe study included 100 patients with a mean age of 55.4 ± 11.8 years. The overall response to FTD/TPI was 4%. The median PFS was 4 months (95% confidence interval (CI) 3.487-4.513), and the median OS was 11 months (95% CI, 9.226-12.771). In a Cox regression analysis of the independent predictors for PFS, advanced stage of the disease (P = 0.037; HR, 2.614; and CI, 1.102-7.524), presence of lymph node metastasis (P = 0.018; HR, 3.664; and 95% CI, 1.187-8.650), and >2 metastatic sites (P = 0.020; HR, 1.723; and 95% CI, 1.089-2.727) were independent factors predicting disease progression. The Cox regression analysis confirmed that age ≥ 55 years (P = 0.046; HR, 1.667; and 95%, 1.097-3.100), advanced disease stage (P = 0.044; HR, 1.283; and 95% CI, 1.035-2.940), prior use of adjuvant chemotherapy (P = 0.037; HR, 0.892; and 95% CI, 0.481-0.994), liver metastasis (P = 0.025; HR, 2.015; and 95% CI, 1.091-3.720), >2 metastatic sites (P = 0.038; HR, 1.248; and 95% CI, 1.036-1.846), development of neutropenia after receiving first cycle of FTD/TPI (P = 0.042; HR, 1.505; and 95% CI, 1.064-2.167), and increased number of FTD/TPI cycles (P = 0.002; HR, 0.769; and 95% CI, 0.664-0.891) were independent variables for OS.ConclusionTreatment with FTD/TPI is feasible and effective in daily clinical practice in Saudi Arabian patients. The risk of progression increased with advanced disease stage, lymph node metastasis, bone metastasis, and metastasis to >2 sites. Age ≥ 55 years, advanced disease stage, liver metastasis, metastasis to >2 sites, neutropenia after the first cycle of FTD/TPI, and increased number of FTD/TPI cycles were independent factors predicting mortality.

Project description:Patients with metastatic colorectal cancer (mCRC) are surviving longer now than ever before, but mortality rates are still high and more effective therapies are clearly needed. For patients with disease that is refractory to fluoropyrimidines, oxaliplatin, irinotecan, and biologic agents targeting the vascular endothelial growth factor and epidermal growth factor receptor pathways, novel treatment options trifluridine/tipiracil (TAS-102) and regorafenib can be effective disease stabilizers. However, objective clinical responses are rare and toxicities are manageable but common. In order to tackle poor clinical responses to TAS-102, there is an ongoing effort to effectively combine this drug with other agents, particularly those targeting angiogenesis. Certain subpopulations appear to benefit more than others from TAS-102; those that benefit often have underlying genetic defects in DNA repair pathways and/or develop neutropenia. In this review, we focus on the role of TAS-102 in the treatment of mCRC, including its use in combination with other agents, potential predictive biomarkers of response to TAS-102, and possible future directions.

Project description:Trifluridine (FTD)/tipiracil (TPI) plus bevacizumab (Bev) is a promising late-line treatment in metastatic colorectal cancer (mCRC). Although chemotherapy-induced neutropenia (CIN) is a well-known predictor of FTD/TPI efficacy, whether CIN is a predictive marker of efficacy for FTD/TPI + Bev remains unclear. Thus, the present study aimed to investigate the clinical outcomes of FTD/TPI + Bev and the predictive markers of its efficacy. Clinical data of patients with mCRC who received FTD/TPI + Bev at the Cancer Institute Hospital between January 2017 and August 2020 were retrospectively collected. Disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and safety were assessed. In addition, subgroup analyses of prognostic and predictive efficacy markers were performed. In total, 94 patients (median age, 60.0 years; age range, 32-82 years; 37 men and 57 women) were included in the present study. The DCR was 44.7%, the median PFS time was 2.9 months (2.3-4.1 months) and the median OS time was 10.0 months (7.3-11.1 months). Grade 3 or 4 CIN within the first cycle of treatment occurred in 27.7% of patients, which was significantly associated with a longer PFS time than those who did not develop CIN [3.8 months (2.3-8.4 months) vs. 2.7 months (1.8-4.0 months); P=0.008]. Furthermore, the DCR was higher in patients with grade 3 or 4 CIN within the first cycle of treatment than those without CIN (61.5 vs. 38.2%; P=0.07). Multivariate Cox regression analysis revealed that grade 3 or 4 CIN within the first cycle of treatment are independent predictors for a longer PFS time (P=0.01). Taken together, the results of the present study suggest that grade 3 or 4 CIN within the first cycle of treatment are early predictors of the efficacy of FTD/TPI + Bev.

Project description:BackgroundThe C-TASK-FORCE phase I/II and Danish randomized phase II trials reported the promising efficacy of trifluridine/tipiracil (TAS102) plus bevacizumab (BEV) in patients with chemorefractory metastatic colorectal cancer (mCRC). However, there had been no direct comparative phase III trial to compare the efficacy between TAS102 plus BEV and standard therapy with either TAS102 or regorafenib monotherapy.MethodsWe retrospectively reviewed the medical records of patients with mCRC who received TAS102 plus BEV, TAS102 monotherapy, or regorafenib monotherapy after standard chemotherapies during 2013-2019.ResultsPatients received TAS102 plus BEV (n = 139), TAS102 monotherapy (n = 153), or regorafenib monotherapy (n = 133). With a median follow-up of 25.3 months, median overall survival (OS) was 11.5 months [95% confidence interval (CI), 9.9-13.9] for TAS102 plus BEV, 8.1 months (95% CI, 6.8-9.2) for TAS102 monotherapy, and 6.8 months (95% CI, 5.7-8.5) for regorafenib monotherapy. The hazard ratios were 0.67 (95% CI, 0.51-0.88) for TAS102 plus BEV versus TAS102 monotherapy and 0.71 (95% CI, 0.54-0.94) for TAS102 plus BEV versus regorafenib monotherapy. Median progression-free survival (PFS) was 4.4 months (95% CI, 3.7-5.4) for TAS102 plus BEV, 2.5 months (95% CI, 1.6-2.3) for TAS102 monotherapy, and 2.1 months (95% CI, 1.6-2.3) for regorafenib monotherapy. The hazard ratios were 0.57 (95% CI, 0.45-0.73) for TAS102 plus BEV versus TAS102 monotherapy and 0.44 (95% CI, 0.34-0.58) for TAS102 plus BEV versus regorafenib monotherapy. On multivariate analysis, TAS102 plus BEV was independently correlated with better OS and PFS. No unexpected adverse events were observed in any group.ConclusionOur study shows that OS and PFS are longer in patients treated with TAS102 plus BEV than in those treated with TAS102 or regorafenib monotherapy.

Project description:BackgroundQuality of life (qol) is important for oncology patients, especially for those with late-stage disease. The present study was initiated to address the lack of published prospective data about the qol benefits of trifluridine/tipiracil (ftd/tpi) compared with best supportive care (bsc) in patients with refractory metastatic colorectal cancer (mcrc).MethodsThis prospective, cross-sectional, non-interventional study used multidimensional validated scales to evaluate patient-reported qol in two study cohorts of patients and also to measure differences in mcrc-related symptoms and pain in a real-world clinical setting.ResultsOur findings demonstrate that patients with refractory mcrc report better overall qol when treated with ftd/tpi than with bsc alone. In that population, statistically significant differences in mean qol measures favoured ftd/tpi over bsc for physical symptom distress, psychological distress, activity impairment, overall valuation of life, and symptomatology. The overall better qol for patients receiving ftd/tpi implies that treatment was well tolerated and was associated with a lower symptom burden. No significant differences for pain were observed between the groups.ConclusionsThis study suggests that ftd/tpi is a well-tolerated option for the treatment of patients with refractory mcrc, showcasing the value of capturing real-world qol data in routine clinical practice.
