- DB11679
- Background
Fruquintinib is a novel small-molecule anti-VEGFR that targets VEGFR-1,-2, and -3 to inhibit angiogenesis. Tumor angiogenesis is one of the most critical biological processes for increasing oxygen and nutrient supply to cancer cells, and the VEGF/VEGFR pathway is one of the most critical pathways for this phenomenon.3,4 Indeed, oncogenic activation, loss of tumor suppressor function, and hypoxia, usually facilitated by cancer cells, are known to upregulate VEGF.2
There are 2 major approaches to combatting tumor angiogenesis: neutralization of VEGF/VEGFR activity through monoclonal antibodies or blockage of VEGFR kinase activity through small-molecule inhibitors. The first approach can be exemplified by bevacizumab, a VEGF-A trap antibody. Although bevacizumab is successful in sustaining target inhibition, mandatory intravenous dosing, immunogenicity, and the potential to induce autoimmune diseases hinder its clinical application.2 For the small-molecule approach, most earlier generations of VEGFR inhibitors such as sunitinib, sorafenib, regorafenib, and pazopanib have poor selectivity, thus increasing the risk of off-target toxicity. Therefore, the advent of fruquintinib, a new generation of VEGFR inhibitors with a high kinome selectivity, demonstrated the feasibility of the small-molecule inhibitor approach.2
On November 8th, 2023, fruquintinib was approved by the FDA under the brand name Fruzaqla for the treatment of adult patients with metastatic colorectal cancer (mCRC) who received prior fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if RAS wild-type and medically appropriate, an anti-EGFR therapy. This approval is based on favorable results obtained from the FRESCO and FRESCO-2 trials, where an increase in overall survival rate was observed in both trials.6

In vitro studies showed fruquintinib inhibited VEGF-mediated endothelial cell proliferation and tubular formation, while in vivo studies demonstrated fruquintinib-mediated tumor growth inhibition in a tumor xenograft mouse model of colon cancer. Inhibition of VEGF-induced VEGFR-2 phosphorylation was illustrated in both in vitro and in vivo studies.5
Fruquintinib exposure-response relationships and the time course of pharmacodynamic response are unknown. A mean increase in QTc interval >20 milliseconds (ms) was not observed at the approved recommended dosage.5
- Mechanism of action
Fruquintinib is a small-molecule kinase inhibitor of vascular endothelial growth factor receptors (VEGFR)-1, -2, and -3 with IC50 values of 33, 35, and 0.5 nM, respectively
Target Actions Organism AVascular endothelial growth factor receptor 1 inhibitorHumans AVascular endothelial growth factor receptor 2 inhibitorHumans AVascular endothelial growth factor receptor 3 inhibitorHumans - Absorption
The fruquintinib steady-state geometric mean (% coefficient of variation [CV]) maximum concentration (Cmax) is 300 ng/mL (28%) and the area under the concentration-time curve for the dosing interval (AUC0-24h) is 5880 ng∙h/mL (29%) at the recommended dosage. The fruquintinib Cmax and AUC0-24h are dose-proportional across the dosage range of 1 to 6 mg (0.2 to 1.2 times the recommended dosage). Fruquintinib steady state is achieved after 14 days with a mean AUC0-24h accumulation of 4-fold.5
The fruquintinib median (min, max) time to Cmax is approximately 2 hours (0, 26 hours).5
No clinically significant differences in fruquintinib pharmacokinetics were observed following administration of a high-fat meal (800 to 1000 calories, 50% fat).5
- Volume of distribution
The mean (SD) apparent volume of distribution of fruquintinib is approximately 46 (13) L.5
- Protein binding
The plasma protein binding of fruquintinib is approximately 95%.5
- Metabolism
Fruquintinib is primarily eliminated by CYP450 and non-CYP450 (i.e., sulfation and glucuronidation) metabolism. CYP3A and to a lesser extent CYP2C8, CYP2C9, and CYP2C19 are the CYP450 enzymes involved in fruquintinib's metabolism.5
- Route of elimination
Following oral administration of a 5 mg radiolabeled fruquintinib dose, approximately 60% of the dose was recovered in urine (0.5% unchanged) and 30% of the dose was recovered in feces (5% unchanged).5
- Half-life
The fruquintinib's mean (SD) elimination half-life is approximately 42 (11) hours.5
- Clearance
The apparent clearance (SD) of fruquintinib is 14.8 (4.4) mL/min.5

Based on findings in animal studies and its mechanism of action, fruquintinib can cause fetal harm when administered to a pregnant woman. In an embryo-fetal developmental study in pregnant rats, oral administration of fruquintinib during the period of organogenesis resulted in teratogenicity and embryo lethality at exposures below the clinical exposure. There are no data on the use of fruquintinib in pregnant women. Advise pregnant women of the potential risk to a fetus.
Carcinogenicity studies have not been conducted with fruquintinib.
Fruquintinib was not mutagenic in the in vitro bacterial reverse mutation (Ames) assay or clastogenicin the in vitro Chinese hamster ovary chromosome aberration assay. Fruquintinib was not genotoxic in the in vivo rat micronucleus or alkaline comet assays.

- Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFB and PGF, and plays an essential role in the development of embryonic vasculature, the regulation of angiogenesis, cell survival, cell migration, macrophage function, chemotaxis, and cancer cell invasion. Acts as a positive regulator of postnatal retinal hyaloid vessel regression (By similarity). May play an essential role as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells. Can promote endothelial cell proliferation, survival and angiogenesis in adulthood. Its function in promoting cell proliferation seems to be cell-type specific. Promotes PGF-mediated proliferation of endothelial cells, proliferation of some types of cancer cells, but does not promote proliferation of normal fibroblasts (in vitro). Has very high affinity for VEGFA and relatively low protein kinase activity; may function as a negative regulator of VEGFA signaling by limiting the amount of free VEGFA and preventing its binding to KDR. Modulates KDR signaling by forming heterodimers with KDR. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate and the activation of protein kinase C. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, leading to activation of phosphatidylinositol kinase and the downstream signaling pathway. Mediates activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Phosphorylates SRC and YES1, and may also phosphorylate CBL. Promotes phosphorylation of AKT1 at 'Ser-473'. Promotes phosphorylation of PTK2/FAK1 (PubMed:16685275)

- Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFC and VEGFD. Plays an essential role in the regulation of angiogenesis, vascular development, vascular permeability, and embryonic hematopoiesis. Promotes proliferation, survival, migration and differentiation of endothelial cells. Promotes reorganization of the actin cytoskeleton. Isoforms lacking a transmembrane domain, such as isoform 2 and isoform 3, may function as decoy receptors for VEGFA, VEGFC and/or VEGFD. Isoform 2 plays an important role as negative regulator of VEGFA- and VEGFC-mediated lymphangiogenesis by limiting the amount of free VEGFA and/or VEGFC and preventing their binding to FLT4. Modulates FLT1 and FLT4 signaling by forming heterodimers. Binding of vascular growth factors to isoform 1 leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate and the activation of protein kinase C. Mediates activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, reorganization of the actin cytoskeleton and activation of PTK2/FAK1. Required for VEGFA-mediated induction of NOS2 and NOS3, leading to the production of the signaling molecule nitric oxide (NO) by endothelial cells. Phosphorylates PLCG1. Promotes phosphorylation of FYN, NCK1, NOS3, PIK3R1, PTK2/FAK1 and SRC

- Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFC and VEGFD, and plays an essential role in adult lymphangiogenesis and in the development of the vascular network and the cardiovascular system during embryonic development. Promotes proliferation, survival and migration of endothelial cells, and regulates angiogenic sprouting. Signaling by activated FLT4 leads to enhanced production of VEGFC, and to a lesser degree VEGFA, thereby creating a positive feedback loop that enhances FLT4 signaling. Modulates KDR signaling by forming heterodimers. The secreted isoform 3 may function as a decoy receptor for VEGFC and/or VEGFD and play an important role as a negative regulator of VEGFC-mediated lymphangiogenesis and angiogenesis. Binding of vascular growth factors to isoform 1 or isoform 2 leads to the activation of several signaling cascades; isoform 2 seems to be less efficient in signal transduction, because it has a truncated C-terminus and therefore lacks several phosphorylation sites. Mediates activation of the MAPK1/ERK2, MAPK3/ERK1 signaling pathway, of MAPK8 and the JUN signaling pathway, and of the AKT1 signaling pathway. Phosphorylates SHC1. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase. Promotes phosphorylation of MAPK8 at 'Thr-183' and 'Tyr-185', and of AKT1 at 'Ser-473'

- A cytochrome P450 monooxygenase involved in the metabolism of sterols, steroid hormones, retinoids and fatty acids (PubMed:10681376, PubMed:11093772, PubMed:11555828, PubMed:12865317, PubMed:14559847, PubMed:15373842, PubMed:15764715, PubMed:19965576, PubMed:20702771, PubMed:21490593, PubMed:21576599). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation of carbon-hydrogen bonds (PubMed:12865317, PubMed:14559847, PubMed:15373842, PubMed:15764715, PubMed:21490593, PubMed:21576599, PubMed:2732228). Exhibits high catalytic activity for the formation of hydroxyestrogens from estrone (E1) and 17beta-estradiol (E2), namely 2-hydroxy E1 and E2, as well as D-ring hydroxylated E1 and E2 at the C-16 position (PubMed:11555828, PubMed:12865317, PubMed:14559847). Plays a role in the metabolism of androgens, particularly in oxidative deactivation of testosterone (PubMed:15373842, PubMed:15764715, PubMed:22773874, PubMed:2732228). Metabolizes testosterone to less biologically active 2beta- and 6beta-hydroxytestosterones (PubMed:15373842, PubMed:15764715, PubMed:2732228). Contributes to the formation of hydroxycholesterols (oxysterols), particularly A-ring hydroxylated cholesterol at the C-4beta position, and side chain hydroxylated cholesterol at the C-25 position, likely contributing to cholesterol degradation and bile acid biosynthesis (PubMed:21576599). Catalyzes bisallylic hydroxylation of polyunsaturated fatty acids (PUFA) (PubMed:9435160). Catalyzes the epoxidation of double bonds of PUFA with a preference for the last double bond (PubMed:19965576). Metabolizes endocannabinoid arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:20702771). Plays a role in the metabolism of retinoids. Displays high catalytic activity for oxidation of all-trans-retinol to all-trans-retinal, a rate-limiting step for the biosynthesis of all-trans-retinoic acid (atRA) (PubMed:10681376). Further metabolizes atRA toward 4-hydroxyretinoate and may play a role in hepatic atRA clearance (PubMed:11093772). Responsible for oxidative metabolism of xenobiotics. Acts as a 2-exo-monooxygenase for plant lipid 1,8-cineole (eucalyptol) (PubMed:11159812). Metabolizes the majority of the administered drugs. Catalyzes sulfoxidation of the anthelmintics albendazole and fenbendazole (PubMed:10759686). Hydroxylates antimalarial drug quinine (PubMed:8968357). Acts as a 1,4-cineole 2-exo-monooxygenase (PubMed:11695850). Also involved in vitamin D catabolism and calcium homeostasis. Catalyzes the inactivation of the active hormone calcitriol (1-alpha,25-dihydroxyvitamin D(3)) (PubMed:29461981)
