- DrugBank Accession Number
- DB11886
- Background
Infigratinib is a pan-fibroblast growth factor receptor (FGFR) kinase inhibitor. By inhibiting the FGFR pathway, which is often aberrated in cancers such as cholangiocarcinoma, infigratinib suppresses tumour growth.1 Cholangiocarcinoma is the most common primary malignancy affecting the biliary tract and the second most common primary hepatic malignancy.2 Infitratinib is a pan-FGFR inhibitor, as it is an ATP-competitive inhibitor of all four FGFR receptor subtypes.1
On May 28, 2021, the FDA granted accelerated approval to infigratinib - under the market name Truseltiq - for the treatment of previously treated, unresectable locally advanced or metastatic cholangiocarcinoma in adults with a fibroblast growth factor receptor 2 (FGFR2) fusion or another rearrangement as detected by an FDA-approved test.5 This approval follows pemigatinib, another FGFR inhibitor approved by the FDA for the same therapeutic indication.

- Pharmacodynamics
Infigratinib is an anti-tumour agent that works to suppress tumour growth in cholangiocarcinoma. It exhibits anti-tumour activity in mouse and rat xenograft models of human tumours with activating FGFR2 or FGFR3 alterations, such as FGFR2-TTC28 or FGFR2-TRA2B fusions.4 In clinical trials, patients with cholangiocarcinoma who were treated with infigratinib had an overall response rate of 23% - where one patient had a complete response - and a duration of response of 5.5 months, with a range between 0.03 and 28.3 months.4,5 Some patients with cancers with FGFR mutations display intrinsic resistance to infigratinib, leading to negligible therapeutic efficacy: investigations are ongoing to target molecular pathways to combat drug resistance.3
- Mechanism of action
Fibroblast growth factor receptors (FGFRs) are tyrosine kinase receptors that play a role in cell proliferation, differentiation, migration, survival, and angiogenesis. Upon binding of extracellular signals, primarily fibroblast growth factors, FGFR dimerizes to promote phosphorylation of downstream molecules and activation of the Ras-mitogen-activated protein kinase (MAPK) pathway. In some cancers, the FGFR signalling pathway is aberrant and disrupted, leading to unregulated cell proliferation and growth, including malignant cells. Alterations in the FGFR receptors, including mutations, amplifications, and fusions, are associated with a wide array of neoplasms, including prostate, urothelial, ovarian, breast, and liver cancer.1 In particular, FGFR2 fusion is closely related to intrahepatic cholangiocarcinoma: recent studies show that up to 45% of patients with intrahepatic cholangiocarcinoma exhibited gene rearrangements resulting in FGFR2 fusion proteins.2 Alterations in FGFR in tumours can lead to constitutive FGFR signalling, supporting the proliferation and survival of malignant cells.4 Infigratinib is a reversible, non-competitive 1 inhibitor of all four FGFR subtypes - FGFR1, FGFR2, FGFR3, and FGFR4 - that blocks FGFR signalling and inhibits cell proliferation in cancer cell lines with activating FGFR amplification, mutations, or fusions. Out of the four FGFR subtypes, infigratinib has the highest affinity for FGFR1, FGFR2, and FGFR3.4 Infigratinib binds to the allosteric site between the two kinase lobes of the FGFR - or more specifically, to the ATP-binding cleft. Binding to this cleft prevents autophosphorylation of the receptor and blocks downstream signalling cascades that would otherwise activate MAPK.1

Mean (%CV) Cmax is 282.5 ng/mL (54%) and AUC0-24h is 3780 ngxh/mL (59%) for infigratinib. Infigratinib Cmax and AUC increase more than proportionally across the dose range of 5 to 150 mg and steady state is achieved within 15 days. At steady state, median time to achieve peak infigratinib plasma concentration (Tmax) is six hours, with a range between two and seven hours.4
Mean (%CV) Cmax is 42.1 ng/mL (65%) for BHS697 and 15.7 ng/mL (92%) for CQM157. Mean (%CV) AUC0-24h is 717 ngxh/mL (55%) for BHS697 and 428 ngxh/mL (72%) for CQM157. In healthy subjects, a high-fat and high-calorie meal increased AUCinf of infigratinib by 80%-120% and Cmax by 60%-80%. The median Tmax also shifted from four hours to six hours. A low-fat low-calorie meal increased the mean AUCinf of infigratinib by 70% and Cmax by 90%/4
- Volume of distribution
At steady state, the geometric mean (CV%) apparent volume of distribution of infigratinib was 1600 L (33%). In rats receiving a single oral dose, infigratinib had brain-to-plasma concentration ratios (based on AUC0-inf) of 0.682.4
- Protein binding
Infigratinib is about 96.8% bound to plasma proteins, primarily to lipoprotein. Protein binding is concentration-dependent.4
- Metabolism
According to in vitro findings, about 94% of infigratinib is metabolized by CYP3A4 and about 6% of the drug is metabolized by flavin-containing monooxygenase 3 (FMO3). About 38% of the dose is circulating parent drug in the plasma and BHS697 and CQM157 are two major metabolites of infigratinib that are each found at >10% of the dose. They are pharmacologically active, with BHS697 representing about 16% to 33% of the overall pharmacological activity of infigratinib and CQM157 contributing to about 9% to 12%. BHS697 undergoes further metabolism mediated by CYP3A4 and CQM157 is metabolized through both Phase I and Phase II biotransformation pathways.4 The exact metabolic pathways and the structure of BHS697 and CQM157 are not fully characterized.
- Route of elimination
Following administration of a single oral dose of radiolabeled infigratinib in healthy subjects, approximately 77% of the dose was recovered in feces, where 3.4% of the dose was in the unchanged parent form. About 7.2% was recovered in urine with 1.9% of the dose was unchanged.4
- Half-life
The geometric mean (CV%) terminal half-life of infigratinib was 33.5 h (39%) at steady state. 4
- Clearance
The geometric mean (CV%) total apparent clearance (CL/F) of infigratinib was 33.1 L/h (59%) at steady state.4

- Infigratinib binds to FGFR1 with IC50 value of 1.1 nM. Its major metabolites, BHS697 and CQM157, have similar in vitro binding affinities for FGFR1, FGFR2, and FGFR3.
- General Function
- Tyrosine-protein kinase that acts as a cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of embryonic development, cell proliferation, differentiation and migration. Required for normal mesoderm patterning and correct axial organization during embryonic development, normal skeletogenesis and normal development of the gonadotropin-releasing hormone (GnRH) neuronal system. Phosphorylates PLCG1, FRS2, GAB1 and SHB. Ligand binding 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. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Promotes phosphorylation of SHC1, STAT1 and PTPN11/SHP2. In the nucleus, enhances RPS6KA1 and CREB1 activity and contributes to the regulation of transcription. FGFR1 signaling is down-regulated by IL17RD/SEF, and by FGFR1 ubiquitination, internalization and degradation

- Tyrosine-protein kinase that acts as a cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of cell proliferation, differentiation, migration and apoptosis, and in the regulation of embryonic development. Required for normal embryonic patterning, trophoblast function, limb bud development, lung morphogenesis, osteogenesis and skin development. Plays an essential role in the regulation of osteoblast differentiation, proliferation and apoptosis, and is required for normal skeleton development. Promotes cell proliferation in keratinocytes and immature osteoblasts, but promotes apoptosis in differentiated osteoblasts. Phosphorylates PLCG1, FRS2 and PAK4. Ligand binding 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. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. FGFR2 signaling is down-regulated by ubiquitination, internalization and degradation. Mutations that lead to constitutive kinase activation or impair normal FGFR2 maturation, internalization and degradation lead to aberrant signaling. Over-expressed FGFR2 promotes activation of STAT1.

- Tyrosine-protein kinase that acts as a cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of cell proliferation, differentiation and apoptosis. Plays an essential role in the regulation of chondrocyte differentiation, proliferation and apoptosis, and is required for normal skeleton development. Regulates both osteogenesis and postnatal bone mineralization by osteoblasts. Promotes apoptosis in chondrocytes, but can also promote cancer cell proliferation. Required for normal development of the inner ear. Phosphorylates PLCG1, CBL and FRS2. Ligand binding 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. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Plays a role in the regulation of vitamin D metabolism. Mutations that lead to constitutive kinase activation or impair normal FGFR3 maturation, internalization and degradation lead to aberrant signaling. Over-expressed or constitutively activated FGFR3 promotes activation of PTPN11/SHP2, STAT1, STAT5A and STAT5B. Secreted isoform 3 retains its capacity to bind FGF1 and FGF2 and hence may interfere with FGF signaling

- General Function
- 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).

- Essential hepatic enzyme that catalyzes the oxygenation of a wide variety of nitrogen- and sulfur-containing compounds including drugs as well as dietary compounds (PubMed:10759686, PubMed:30381441, PubMed:32156684). Plays an important role in the metabolism of trimethylamine (TMA), via the production of trimethylamine N-oxide (TMAO) metabolite (PubMed:9776311). TMA is generated by the action of gut microbiota using dietary precursors such as choline, choline containing compounds, betaine or L-carnitine. By regulating TMAO concentration, FMO3 directly impacts both platelet responsiveness and rate of thrombus formation (PubMed:29981269)
