Direct randomized comparisons of regorafenib, TAS-102, and fruquintinib for treating metastatic colorectal cancer (mCRC) are lacking. Here, we evaluated the efficacy and safety of three agents by a systematic review and a network meta-analysis.. We included phase III randomized controlled trials in the PubMed, Embase, and Scopus Cochrane databases and ClinicalTrials.gov registry from initiation until January 2019. Data from randomized controlled trials including overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were extracted. Direct meta-analysis and indirect meta-analysis using network meta-analysis were assessed.. Five trials comprising a total of 2586 patients were included. For efficacy analysis of OS, no statistically significant differences were observed between regorafenib and TAS-102 (HR 0.945, 95% CI [0.677, 1.320], P = 0.753), regorafenib and fruquintinib (HR 1.056, 95% CI [0.690, 1.621], P = 0.814), or TAS-102 and fruquintinib (HR 1.117, 95% CI [0.740, 1.685], P = 0.610). However, fruquintinib was superior in PFS compared with TAS-102 (HR 1.756, 95% CI [1.079, 2.857], P = 0.023). Regorafenib and TAS-102 appeared to have a similar effect on PFS (HR 0.907, 95% CI [0.611, 1.346], P = 0.641), as did regorafenib and fruquintinib (HR 1.592, 95% CI [0.968, 2.618], P = 0.067). None of the three agents were better in terms of all grade AEs or any grade of 3-5 AEs. However, subgroup analysis of AEs exhibited different toxicity profiles between the three drugs.. Indirect comparison suggested that the three agents had similar OS but that fruquintinib was superior in terms of PFS compared with that of TAS-102. These three agents had different toxicity profiles.

The optimal treatment in the third-line and later-line setting for metastatic colorectal cancer (mCRC) has not been established. As reported, regorafenib and fruquintinib have shown to be superior to placebo in mCRC. However, no direct clinical comparison of regorafenib and fruquintinib has been conducted; we performed a systematic review and network meta-analysis to compare the efficacy and safety of regorafenib and fruquintinib.. PubMed, Embase, and the Cochrane Library were systematically searched and randomized-controlled trials (RCTs) assessing the effect and safety of regorafenib or fruquintinib versus placebo for patients with mCRC were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. After that, we performed pairwise direct meta-analyses (regorafenib vs. placebo and fruquintinib vs. placebo) and indirect comparison (regorafenib vs. fruquintinib) using network meta-analyses methods.. Three RCTs involving 1380 patients were included in the meta-analysis. In the direct meta-analysis, regorafenib and fruquintinib both showed survival benefits when compared with placebo. For the indirect comparison, fruquintinib shows no significant difference in OS compared to regorafenib (HR 0.97; 95% CI 0.64-1.46). Regarding PFS, there was a tendency that fruquintinib was superior to regorafenib (HR 0.65; 95% CI 0.39-1.08); however, there was no statistic difference. For the safety analysis, in indirect comparison, fruquintinib showed significant difference in all-grade toxicity compared to regorafenib (OR 0.73; 95% CI 0.65-0.82), especially in subgroup of proteinuria (OR 0.31; 95% CI 0.11-0.86). For the grade 3-5 toxicity, fruquintinib showed no significant difference when compared with regorafenib (OR 0.92; 95% CI 0.64-1.32).. Based on efficacy and safety, there was a tendency that fruquintinib was superior to regorafenib, as a whole, regorafenib and fruquintinib demonstrated similar clinical benefit for patients with refractory mCRC. It seems that fruquintinib has less toxic in all-grade toxicity when compared with regorafenib.

To evaluate the cost-effectiveness of addition of fruquintinib to best supportive care (BSC) in third-line treatment for patients with metastatic colorectal cancer (CRC).. To conduct the cost-effectiveness analysis, a Markov model was established to simulate the course of metastatic CRC. Three health states-progression-free survival (PFS), progressive disease (PD), and death-were included. Clinical data were derived from the FRESCO trial and health utility values were extracted from previous literature. The primary outcome of the study was incremental cost-effectiveness ratio (ICER) in US dollars per quality-adjusted life-years (QALYs) from a Chinese societal perspective. One-way sensitivity analyses and probabilistic sensitivity analyses were performed to test the robustness of the study.. Addition of fruquintinib to BSC gained 0.54 QALY at a cost of $15,404.57 while the BSC group gained 0.38 QALY at a cost of $9603.94. ICER of fruquintinib versus BSC was $36,253.94/QALY. In the 1-way sensitivity analyses, utility for PD in both groups, utility for PFS in both groups, and cost of fruquintinib significantly influenced the results of the analysis. At the willingness-to-pay threshold of $28,988.40/QALY, probabilities of addition of fruquintinib to BSC or BSC alone as the cost-effective option were 0% and 100%, indicating addition of fruquintinib is not a dominant option compared with BSC.. Addition of fruquintinib to BSC is not a cost-effective regimen in the third-line setting for patients with metastatic CRC from the Chinese societal perspective.

In this study, we analyze the cost-effectiveness of fruquintinib as third-line treatment for patients with metastatic colorectal cancer in China, especially after a recent price drop suggested by the National Healthcare Security Administration.. A Markov model was developed to investigate the cost-effectiveness of fruquintinib compared to placebo among patients with metastatic colorectal cancer. Effectiveness was measured in quality-adjusted life years (QALY). The Chinese healthcare payer's perspective was considered with a lifetime horizon, including direct medical cost (2019 US dollars [USD]). A willing-to-pay threshold was set at USD 27,130/QALY, which is three times the gross domestic product (GDP) per capita. We examined the robustness of the model in one-way and probabilistic sensitivity analysis.. Fruquintinib was associated with better health outcomes than placebo (0.640 vs 0.478 QALYs) with a higher cost (USD 20750.9 vs USD 12042.2), resulting in an incremental cost-effectiveness ratio (ICER) of USD 53508.7 per QALY. This ICER is 25% lower than the one calculated before the price drop (USD 70952.6 per QALY).. After the price negotiation, the drug becomes cheaper and the ICER is lower, but the drug is still not cost effective under the standard of 3 times GDP willing-to-pay threshold. For patients with metastatic colorectal cancer in China, fruquintinib is not a cost-effective option under the current circumstances in China.

Fruquintinib is a potent, highly selective and orally active inhibitor of VEGFR1, 2, 3 tyrosine kinases. It inhibits VEGF-induced VEGFR2 phosphorylation, endothelial cell proliferation and tubule formation. Currently, it has been approved for the treatment of metastatic colorectal cancer in patients who have failed at least two prior systemic antineoplastic therapies in China. However, it is not approved outside China, and there is another similar small molecular VEGFR multitarget drug approved in China, USA, Europe, etc. Here, we summarize the mechanism characteristics and clinical development of fruquintinib supporting its use in the treatment of metastastic colorectal cancer as well as explorations in other tumor types.
