Abstract
Background Present study was condeucted to investigate the efficacy and safety of regorafenib for patients with previously treated metastatic colorectal cancer (mCRC) in a Chinese population and the prognostic implications of adverse reactions. Methods This retrospective study a total of 96 consecutive patients with mCRC who had failed standard chemotherapy regimens from June 2017 to December 2020. Patients received regorafenib at an initial dosage of 160 mg or 120 mg. The primary end point was progression-free survival (PFS), and secondary end points objective response rate (ORR), disease-control rate (DCR), overall survival (OS), safety, and associations between prognosis and adverse-reaction status. Results There were three patients with partial response, 49 with stable disease, and 44 with progressive disease. Consequently, the ORR and DCR of the 96 patients were 3.1% (95% CI 0.6%–8.9%) and 54.2% (95% CI 43.7–64.4%), respectively. Prognosis results showed that median PFS of the 96 patients was 2.5 (95% CI 1.98–3.02) months and median OS 9.8 (95% CI 7.02–12.59) months. Additionally, the most frequent adverse reactions during regorafenib treatment were hand–foot syndrome (HFS; 52.1%), hypertension (38.5%), and fatigue (33.3%). Interestingly, the relevance of prognosis to adverse-reaction status exhibited that median PFS of patients with HFS and patients without HFS was 3.3 months and 2.0 months, respectively (P=0.013). Similarly, median PFS of patients with hypertension and without hypertension was 3.6 months and 2.2 months, respectively (P=0.023). Conclusion Potential clinical benefit of regorafenib monotherapy was observed for patients with mCRC who had failed standard chemotherapy regimens. Hypertension and HFS induced by regorafenib therapy could be used as valuable biomarkers to predict the prognosis of regorafenib.

Abstract
Peritoneal carcinomatosis from colorectal cancer (CRC) has a poor prognosis with median survival and clinical responses that are worse than for other metastatic sites, and even more so in pretreated patients proposed for regorafenib therapy. Thus, patients with these characteristics are a therapeutic challange. The present study reports the case of an 83-year-old woman with diffuse peritoneal carcinomatosis from CRC, RAS-mutated, and treated with second-line therapy with the off-label administration of regorafenib at full dose (160 mg once daily, for the first 21 days of each 4-week cycle), refusing conventional chemotherapy. The patient reported an unexpected clinical response, reduced toxicity, excellent adherence to therapy and remained progression-free for 30 months from the start of treatment. In clinical practice, an earlier use of regorafenib and a different selection of patients could be the subject of future studies.

Sequential Treatment with Bevacizumab and Aflibercept for Metastatic Colorectal Cancer in Real-World Clinical Practice. Target Oncol 2020; 15:193-201. [PMID: 32052341 DOI: 10.1007/s11523-020-00705-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/19/2022]
Abstract
BACKGROUND Bevacizumab and aflibercept are currently the mainstay of antiangiogenic therapy for metastatic colorectal carcinoma (mCRC). They are often used in sequence with first- and second-line chemotherapy, especially in patients with RAS-mutated tumours. OBJECTIVE The aim of the present study was to investigate the outcomes of patients with mCRC treated with the bevacizumab-aflibercept sequence in real-world clinical practice. PATIENTS AND METHODS Data from a national clinical registry of targeted therapies for mCRC were analysed retrospectively. Overall, there were 366 patients with valid data who received first-line treatment with bevacizumab and chemotherapy followed by aflibercept with chemotherapy. The majority of the patients (n = 296, 80.8%) had RAS mutated tumours. RESULTS Median cumulative progression-free survival (PFS) from the start of the bevacizumab-containing regimen to progression on aflibercept was 18.2 months (95% CI 16.8-19.5). Median PFS for bevacizumab and aflibercept was 10.6 months (95% CI 9.5-11.7) and 5.6 months (95% CI 5.1-6.1), respectively. Longer PFS on aflibercept was associated with metachronous metastatic disease and longer PFS on bevacizumab. Median overall survival (OS) from the start of first-line bevacizumab was 32.0 months (95% CI 26.6-37.5). The presence of metastatic disease at diagnosis was associated with worse OS. CONCLUSIONS Patients treated with aflibercept in real-world clinical practice achieved similar survival outcomes as those treated within randomised trials. Cumulative survival data provide a benchmark for future studies and enable indirect comparisons with other treatment sequences used in mCRC.

Abstract
Over the past 20 years, management of patients with metastatic colorectal cancer (mCRC) has improved considerably, leading to increased overall survival and more patients eligible for third- or later-line therapy. Currently, two oral therapies are recommended in the third-line treatment of mCRC, regorafenib and trifluridine/tipiracil. Selecting the most appropriate treatment in the third-line setting poses different challenges compared with treatment selection at earlier stages. Therefore, it is important for physicians to understand and differentiate between available treatment options and to communicate the benefits and challenges of these to patients. In this narrative review, practical information on regorafenib is provided to aid physicians in their decision-making and patient communications in daily practice. We discuss the importance of appropriate patient selection and adverse events management through close patient monitoring and dose adjustments to ensure patients stay on treatment for longer and receive as much benefit as possible. We also highlight key physician-patient communication points to facilitate shared decision-making.

Abstract
Purpose Regorafenib is an oral multikinase inhibitor approved for the therapy of previously treated metastatic colorectal carcinoma (mCRC). The aim of the present study was to analyze the outcomes of treatment with regorafenib in real-world clinical practice based on data from a national registry. Methods The CORECT registry, the Czech non-interventional database of patients with mCRC treated with targeted agents, searched for patients with metastatic CRC treated with regorafenib. In total, 555 evaluable patients were identified. Results The median age at diagnosis was 61.7 years. All patients had disease progression on or after previous systemic treatment. Most patients were treated with an initial dose of 160 mg daily (n = 463; 83.6%). The median duration of treatment was 2.7 months (range 0.0-23.4 months). By the data cut-off date, 472 patients (85%) had completed treatment with regorafenib and were evaluable for treatment response evaluation. Partial response was reported in 13 patients (2.8%) and disease stabilization in 130 patients (27.5%). Median progression-free survival (PFS) and overall survival (OS) were 3.5 months (95% confidence interval [CI] 3.2-3.7 months) and 9.3 months (95% CI 8.3-10.3 months), respectively. The 6-month OS rate was 67.7% (95% CI 63.4-72.1%). Multivariable analysis showed that female gender, longer interval from diagnosis of metastatic disease, M0 stage at diagnosis, and Eastern Cooperative Oncology Group performance status (ECOG PS) 0 were associated with longer PFS, while higher body-mass index (BMI), longer interval from diagnosis of metastatic disease, and ECOG PS of 0 were associated with longer OS. Conclusion OS of patients treated with regorafenib in the real-world clinical practice in this cohort exceeded that reported in randomized trials. Regorafenib is a safe and active treatment option for a subgroup of patients with mCRC who are progressing after other systemic therapies and maintain good performance status.

VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2019; 22:1370-1377. [PMID: 31806193 DOI: 10.1016/j.jval.2019.06.010] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Revised: 06/07/2019] [Accepted: 06/19/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND In situations of markedly different population characteristics and weak population overlap, inverse propensity score (PS) weights suffer from extreme values. The new propensity score weighting method using overlap weights (PSOW) overcomes this limitation by estimating the overlap population at the point of highest mutual overlap, thus may be preferred to other balancing methods (trimming, target, or inverse weights) in some situations. OBJECTIVES To evaluate the performance of PSOW with regorafenib effectiveness data from previously treated patients with metastatic colorectal cancer based on the Czech national registry data (regorafenib) and a global phase 3 randomized clinical trial (RCT) (placebo). The second goal was to assess the cost-effectiveness of regorafenib versus placebo. METHODS Individual data on progression-free survival (PFS)/overall survival (OS) were balanced via PSOW for age, sex, Eastern Cooperative Oncology Group performance status, number of treatment lines, metastatic colorectal cancer location, KRAS mutation, and time from metastases estimated using logistic regression. The weighted Kaplan-Meier PFS/OS curves were used in a 3-state partitioned survival model. The R code is provided. RESULTS In comparison with target or inverse PS weights, PSOW showed remarkable performance measured by effective sample size and PS weight distribution or extreme weights despite the weak overlap between the registry and RCT. In the registry or RCT cohort, regorafenib provided better survival compared with the RCT. The new PSOW hazard ratio for OS was 0.53 (RCT: 0.79), which is conservative compared with inverse or target weights with a hazard ratio of 0.44 and 0.27, respectively. CONCLUSION This is the first use of PSOW for clinical data and cost-effectiveness analysis. It is promising in cases of weak or small population overlap and makes pharmacoeconomic modeling, in such cases, feasible.

Abstract
An increasing number of patients with metastatic colorectal cancer (mCRC) are able to receive 3 or more lines of therapy. Treatments in this setting can include regorafenib (an oral multikinase inhibitor), trifluridine/tipiracil hydrochloride (TAS-102), antibodies that target epidermal growth factor receptor for patients with RAS wild-type tumors (if no prior exposure), and, where approved, anti-programmed cell death protein 1 inhibitors for patients with microsatellite instability-high mCRC. Although guidelines describe the available treatment options, few insights are provided to guide selection and sequencing. In this article, we share expert opinion from diverse geographic regions, to offer guidance for best practice when selecting and managing third-line treatment for mCRC. Various factors, including performance status, age, and tumor sidedness, can be used to guide treatment selection. Biomarkers, such as RAS, BRAF, and microsatellite instability, can be useful for treatment stratification. Management of adverse events, to maintain quality of life, is a key consideration and is crucial to best practice in this setting. Common toxicities associated with third-line treatments are hand-foot skin reaction, fatigue, diarrhea, and cytopenias. Patients who receive third-line and later-line treatments should be monitored for these events, especially during the first 2 cycles. Dose modifications can also be used to manage toxicities and to minimize the effect on quality of life, while maximizing treatment benefit. Clinical trials of emerging agents, new treatment combinations, and novel therapies continue the efforts to improve outcomes for patients with mCRC. Sharing expert opinions on best practice for treatment selection and management can ultimately improve outcomes for patients with mCRC.

Optimizing Treatment Sequence for Late-line Metastatic Colorectal Cancer Patients Using Trifluridine/Tipiracil and Regorafenib. Clin Colorectal Cancer 2018; 17:274-279. [PMID: 30042010 DOI: 10.1016/j.clcc.2018.05.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2018] [Revised: 05/08/2018] [Accepted: 05/31/2018] [Indexed: 11/30/2022]
Abstract
BACKGROUND Treatment sequencing for patients with refractory metastatic colorectal cancer (mCRC) has been highly debated. The thymidine-based nucleoside trifluridine/tipiracil (TAS-102) and the multikinase inhibitor regorafenib have demonstrated clinical benefits in randomized phase III trials compared with placebo. However, limited data are available on the most optimal therapy sequence involving TAS-102 and regorafenib. PATIENTS AND METHODS In the present retrospective, observational, real-life study, clinical data on mCRC patients treated with TAS-102 or an alternative salvage treatment at the Medical University of Vienna and University Hospital Zurich were collected from January 2013 to December 2016. RESULTS A total of 85 patients whose disease had progressed during fluoropyrimidine-based therapy (FBT) with or without an antibody were included. The disease control rate in patients treated with TAS-102 after FBT-based treatment was 24% compared with 35% in patients treated with regorafenib after FBT-based treatment (adjusted odds ratio, 1.75; 95% confidence interval, 0.41-7.47; P = .449). The progression-free survival (PFS) and overall survival (OS) for patients treated with TAS-102 was 2.8 months (quartile, 2.0-4.8 months) and 15.9 months, respectively. When the data were analyzed according to the subgroups of patients with or without an FBT-free period, the TAS-102-treated patients with a previous FBT-free interval had a PFS of 3.1 months and OS of 17.7 months compared with a PFS of 2.2 months and OS of 8.1 months for patients who received TAS-102 immediately after FBT. CONCLUSION Our results have confirmed the efficacy of TAS-102 and regorafenib in the real-life setting. The treatment sequence analysis showed a tendency for longer PFS and OS for TAS-102-treated patients after an FBT-free interval. Prospective randomized data are needed to gain more information about the most beneficial therapy sequence in the salvage treatment of mCRC.

Abstract
Colorectal cancer (CRC) is a major public health problem in the United States with an estimated 50,260 deaths in 2017. Over the past two decades, several agents have been approved by the US Food and Drug Administration (FDA) for the treatment of patients with metastatic CRC (mCRC). Regorafenib (BAY 73-4506) is a small-molecule multikinase inhibitor that was approved for the treatment of mCRC in 2012. This agent is a novel oral diphenylurea-based multikinase inhibitor that is active against several angiogenic receptor tyrosine kinases (RTKs; VEGFR-1, VEGFR-2, VEGFR-3, TIE-2), oncogenic RTKs (c-KIT, RET), stromal RTKs (PDGFR-B, FGFR-1), and intracellular signaling kinases (c-RAF/RAF-1, BRAF, BRAFV600E). Preclinical studies have documented its broad-spectrum activity against different solid tumor types including CRC. Phase I studies showed that it had an acceptable safety profile in advanced refractory mCRC. A subsequent Phase III trial (CORRECT) demonstrated significant clinical efficacy of regorafenib in patients with refractory or advanced mCRC, which eventually led to its FDA approval for the treatment of mCRC in September 2012. However, the drug was associated with significant toxicity in clinical practice when administered at the approved doses, which necessitated a thorough reassessment of its dosing schedule and toxicity profile. This review summarizes the development of regorafenib from the initial preclinical studies to the Phase III trials and critically examines the current clinical space occupied by regorafenib in the treatment of mCRC, at 5 years after its initial FDA approval.

Abstract
Abstract
The aim of the present study was to investigate the association of peripheral-blood cell count (PBC)-derived ratios, other biomarkers of inflammation and biomarkers of tumor growth with outcome in a cohort of patients presenting for the next line of therapy after the failure of prior systemic treatment. The data of 51 patients with advanced/metastatic colorectal carcinoma treated with cetuximab in the second or higher line of therapy were retrospectively analyzed. The median duration of cetuximab therapy and the median survival were 5.1 and 12.1 months, respectively. C-reactive protein (CRP), but not urinary neopterin correlated significantly with PBC-derived ratios. Both CRP and urinary neopterin correlated positively with carcinoembryonic antigen (CEA) concentrations and biomarkers of liver dysfunction. Although a number of parameters predicted overall survival in univariate analysis, only hemoglobin, CEA change and serum bilirubin were independent predictors of survival. In conclusion, in patients with metastatic colorectal carcinoma and predominantly liver metastases, the outcome of therapy in the advanced line setting was associated with initial hemoglobin level, a decrease of CEA concentration and initial presence of liver dysfunction. Urinary neopterin did not correlate with PBC-derived ratios, in contrast to CRP, but both urinary neopterin and serum CRP concentrations correlated with laboratory parameters of liver dysfunction.

Cancer Treat Rev 2017; 62:61-73. [PMID: 29175677 DOI: 10.1016/j.ctrv.2017.10.011] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2017] [Revised: 10/25/2017] [Accepted: 10/26/2017] [Indexed: 12/16/2022]
Abstract
PURPOSE Despite advances in the treatment of colorectal cancer, third-line treatment options are still limited. Regorafenib was approved in 2012 for the treatment of patients with metastatic colorectal cancer previously treated with approved standard therapy. The purpose of this review is to present existing clinical data on regorafenib. METHOD We systematically searched the PubMed and Embase databases, as well as ASCO and ESMO conference abstracts, for studies in English including ≥30 patients, evaluating the efficacy and safety of regorafenib in patients with metastatic colorectal cancer. A meta-analysis was conducted on the published, randomized phase III trials. RESULTS 24 eligible studies were included. In two phase III trials, regorafenib significantly increased overall survival (OS), progression free survival (PFS), and disease control rate when compared to placebo. Survival benefits of 1.4 and 2.5 months were presented. The meta-analysis indicated a significant greater treatment effect on OS (hazard ratio 0.67) and PFS (hazard ratio 0.40), compared to placebo. The non-randomized studies mostly supported these results. The most frequently reported adverse events were hand-foot-skin reaction (25%-86%), hypertension (11%-47%) and fatigue (2%-73%). CONCLUSION Large phase III randomized trials indicate that regorafenib provides a benefit in OS and PFS when compared to placebo. Adverse events were common, but manageable and typical of multi-target tyrosine kinase inhibitors. Further research is needed to investigate alternative approaches to the dosing of regorafenib and to explore clinical and molecular biomarkers that can guide patient selection.
