Background

Trifarotene is a topical retinoid cream used in the treatment of acne vulgaris that was first approved for use in the United States in October 2019.6 Retinoids are a class of medications structurally and functionally analogous to vitamin A, though later generation retinoids such as trifarotene and adapalene bear little structural resemblance to vitamin A and are analogous only in function.5 Trifarotene is considered the first of the "fourth-generation" retinoids due to its uniquely selective activity - this selectivity appears to confer improved efficacy and reduced side effects as compared to older, less selective retinoids.1

Pharmacodynamics

Trifarotene exerts its effects via agonism at retinoid receptors - these receptors function to alter DNA transcription, resulting in downstream modulation of the expression of various genes involved in acne pathogenesis.5 It may be associated with skin irritation and should not be applied to cuts, abrasions, or otherwise damaged skin. As trifarotene may result in photosensitivity, patients should be cautioned to avoid excess sun exposure and to use sunscreen and/or protective clothing if exposure is unavoidable.6

Mechanism of action

Trifarotene is a potent and selective agonist of retinoic acid receptor-γ (RAR-γ). It has significantly less activity at RAR-β and RAR-α (16- and 65-fold lower than activity at RAR-γ, respectively), and has no activity at retinoid X receptors (RXRs).1 Agonism at retinoic acid receptors results in dimerization, and the resulting receptor-ligand dimer binds to specific DNA regulatory sequences (retinoic acid response elements, or RAREs) in the promotor regions of retinoid-responsible genes. Downstream alterations to gene expression induced by binding to these regions is the principle mechanism through which trifarotene exerts its comedolytic, anti-inflammatory, and depigmenting effects.6

Like other retinoids, trifarotene influences the expression of a number of genes involved in retinoid metabolism, epidermal differentiation/proliferation, and epidermal response to stress. In addition, trifarotene appears to modulate retinoid-mediated pathways involved in proteolysis, skin hydration, and cell adhesion - modulation of these additional pathways has not been observed with other retinoids and may therefore be unique to trifarotene.1

Absorption

Systemic absorption of trifarotene is minimal. In a pharmacokinetic study involving 19 subjects, systemic concentrations were only quantifiable in 7 - steady state Cmax values ranged from undetectable (<5 pg/mL) to 10 pg/mL and AUC0-24h ranged from 75 to 104 pg.h/mL.6

Protein binding

Trifarotene is 99.9% protein bound in plasma.6

Metabolism

Trifarotene is rapidly metabolized in human hepatocytes - its observed half-life in human keratinocytes is >24 hours, whereas half-life in human liver microsomes is approximately 5 minutes.1 Metabolism of trifarotene is catalyzed primarily by CYP2C9, CYP3A4, CYP2C8, and, to a lesser extent, CYP2B6.6

Route of elimination

Trifarotene is eliminated primarily in the feces.6

Half-life

The terminal half-life of trifarotene is typically between 2 to 9 hours.6

Toxicity

Trifarotene does not appear to carry any risk of carcinogenesis when used at standard doses.6 Systemic exposures in mice following both topical and oral administration were up to 1642 times higher than those seen in humans at the maximal recommended human dose, and these systemic concentrations did not result in observed carcinogenicity. Data regarding overdosage of trifarotene is unavailable.

General Function
Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RAR/RXR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, acts mainly as an activator of gene expression due to weak binding to corepressors. Required for limb bud development. In concert with RARA or RARB, required for skeletal growth, matrix homeostasis and growth plate function (By similarity)

General Function
Receptor for retinoic acid (PubMed:16417524, PubMed:19850744, PubMed:20215566, PubMed:21152046, PubMed:37478846). Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes (PubMed:28167758, PubMed:37478846, PubMed:21152046). The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5 (PubMed:19398580, PubMed:28167758). In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone deacetylation, chromatin condensation and transcriptional suppression (PubMed:16417524). On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation (PubMed:19850744, PubMed:20215566, PubMed:9267036, PubMed:37478846). Formation of a complex with histone deacetylases might lead to inhibition of RARE DNA element binding and to transcriptional repression (PubMed:28167758). Transcriptional activation and RARE DNA element binding might be supported by the transcription factor KLF2 (PubMed:28167758). RARA plays an essential role in the regulation of retinoic acid-induced germ cell development during spermatogenesis (By similarity). Has a role in the survival of early spermatocytes at the beginning prophase of meiosis (By similarity). In Sertoli cells, may promote the survival and development of early meiotic prophase spermatocytes (By similarity). In concert with RARG, required for skeletal growth, matrix homeostasis and growth plate function (By similarity). Together with RXRA, positively regulates microRNA-10a expression, thereby inhibiting the GATA6/VCAM1 signaling response to pulsatile shear stress in vascular endothelial cells (PubMed:28167758). In association with HDAC3, HDAC5 and HDAC7 corepressors, plays a role in the repression of microRNA-10a and thereby promotes the inflammatory response (PubMed:28167758)

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.

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) (PubMed:11093772, PubMed:14559847, PubMed:15766564, PubMed:19965576, PubMed:7574697). Primarily catalyzes the epoxidation of double bonds of polyunsaturated fatty acids (PUFA) with a preference for the last double bond (PubMed:15766564, PubMed:19965576, PubMed:7574697). Catalyzes the hydroxylation of carbon-hydrogen bonds. Metabolizes all trans-retinoic acid toward its 4-hydroxylated form (PubMed:11093772). Displays 16-alpha hydroxylase activity toward estrogen steroid hormones, 17beta-estradiol (E2) and estrone (E1) (PubMed:14559847). Plays a role in the oxidative metabolism of xenobiotics. It is the principal enzyme responsible for the metabolism of the anti-cancer drug paclitaxel (taxol) (PubMed:26427316)

General Function
A cytochrome P450 monooxygenase involved in the metabolism of endocannabinoids and steroids (PubMed:12865317, PubMed:21289075). 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 epoxidation of double bonds of arachidonoylethanolamide (anandamide) to 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:21289075). Hydroxylates steroid hormones, including testosterone at C-16 and estrogens at C-2 (PubMed:12865317, PubMed:21289075). Plays a role in the oxidative metabolism of xenobiotics, including plant lipids and drugs (PubMed:11695850, PubMed:22909231). Acts as a 1,4-cineole 2-exo-monooxygenase (PubMed:11695850)
