Deucravacitinib

Identification

Summary

Deucravacitinib is a TYK2 inhibitor being investigated as a treatment for psoriasis.

Generic Name

Deucravacitinib

DrugBank Accession Number

DB16650

Background

Deucravacitinib is a novel oral selective tyrosine kinase 2 (TYK2) inhibitor. Unlike other Janus kinase 1/2/3 inhibitors that bind to the conserved active domain of these non-receptor tyrosine kinases, deucravacitinib binds to the regulatory domain of TYK2 with high selectivity to this therapeutic target.^1,2 This selectivity towards TYK2 may lead to an improved safety profile of deucravacitinib, as nonselective JAK inhibitors are associated with a range of adverse effects such as altered cholesterol and triglyceride levels and liver and kidney dysfunction.² Deucravacitinib was first approved by the FDA in September 2022 to treat moderate-to-severe plaque psoriasis.⁵

Pharmacodynamics

Deucravacitinib is a tyrosine kinase 2 (TYK2) inhibitor that works to suppress the immune signaling pathways in inflammatory disorders, such as plaque psoriasis. In clinical studies comprising patients with psoriasis, deucravacitinib reduced psoriasis-associated gene expression in psoriatic skin in a dose dependent manner, including reductions in IL-23-pathway and type I IFN pathway regulated genes. Following 16 weeks of once-daily treatment, deucravacitinib reduced inflammatory markers such as IL-17A, IL-19 and beta-defensin by 47 to 50%, 72%, and 81 to 84%, respectively.⁵ Deucravacitinib does not affect with JAK2-dependent hematopoietic functions.⁴

Mechanism of action

Tyrosine kinase 2 (TYK2) is a member of the Janus kinase (JAK) family of kinases, which are intracellular tyrosine kinases that activate the JAK–signal transducer and activator of the transcription pathway. Unlike other members of the JAK family that promote broader immune and extra-immune pathways, such as lipid metabolism, the TYK2 signalling pathway is responsible for selected immune pathways.¹ TYK2 mediates the signalling of inflammatory cytokines of both adaptive (e.g., interleukin (IL) 12 and IL-23) and innate (e.g., type I interferons) immune responses.³ IL-23 has been implicated in the pathogenesis of immune-mediated disorders such as psoriasis and psoriatic arthritis.¹ It activates and promotes the proliferation of Th17 cells: subsequently, Th17 cells secrete inflammatory mediators, such as IL-17 and tumour necrosis factor-alpha, that stimulate epidermal cells to produce cytokines and chemokines that attract and activate innate immune system cells.^1,2 Enhanced activity of Th17 cells leads to sustained inflammatory responses in the skin and joints as manifested in psoriatic arthritis.¹

Deucravacitinib inhibits TYK2 via an allosteric mechanism: it binds to the enzyme's regulatory domain - also known as the pseudokinase (JH2) domain - instead of the catalytic domain. This binding activity allows high selectivity towards TYK2 over other tyrosine kinase enzymes. In in vitro cellular assays, deucravacitinib showed a 100-fold to 2000-fold selectivity for TYK2 over JAK 1/2/3 and demonstrated minimal or no activity against JAK 1/2/3. Upon binding to TYK2, deucravacitinib induces a conformational change and locks the regulatory domain of TYK2 into an inhibitory confirmation with the catalytic domain, trapping TYK2 in an inactive state.^1,2 Inhibiting TYK2 leads to the downregulation of the IL-23/TH17 pathway, IL-12 signalling, type 1 interferon pathway, and keratinocyte activation.³

Absorption

Following oral administration, deucravacitinib plasma Cmax and AUC increased proportionally over a dose range from 3 mg to 36 mg (0.5 to 6 times the approved recommended dosage) in healthy subjects. The steady state C_max and AUC₂₄ of deucravacitinib following administration of 6 mg once daily were 45 ng/mL and 473 ng x hr/mL, respectively. The steady state Cmax and AUC24 of the active deucravacitinib metabolite, BMT-153261, following administration of 6 mg once daily were 5 ng/mL and 95 ng x hr/mL, respectively. The absolute oral bioavailability of deucravacitinib was 99% and the median T_max ranged from two to three hours.⁵

A high-fat, high-calorie meal decreased C_max and AUC of deucravacitinib by 24% and 11%, respectively, and prolonged T_max by one hour; however, this has clinically significant effects on drug absorption and exposure.⁵

Volume of distribution

The volume of distribution of deucravacitinib at steady state is 140 L.⁵

Protein binding

Protein binding of deucravacitinib was 82 to 90% and the blood-to-plasma concentration ratio was 1.26.⁵

Metabolism

Deucravacitinib undergoes N-demethylation mediated by cytochrome P-450 (CYP) 1A2 to form major metabolite BMT-153261, which has a comparable pharmacological activity to the parent drug. However, the circulating exposure of BMT-153261 accounts for approximately 20% of the systemic exposure of the total drug-related components. Deucravacitinib is also metabolized by CYP2B6, CYP2D6, carboxylesterase (CES) 2, and uridine glucuronyl transferase (UGT) 1A9.⁵

Route of elimination

After a single dose of radiolabeled deucravacitinib, approximately 13% and 26% of the dose was recovered as unchanged in urine and feces, respectively. Approximately 6% and 12% of the dose was detected as BMT-153261 in urine and feces, respectively.⁵

Half-life

The terminal half-life of deucravacitinib was 10 hours.⁵

Clearance

The renal clearance of deucravacitinib ranged from 27 to 54 mL/minute.⁵

Toxicity

No information regarding the acute toxicity profile and LD₅₀ of deucravacitinib is available. There is no experience regarding human overdosage with deucravacitinib. There is no known antidote for deucravacitinib overdose and hemodialysis is unlikely to be effective, as the extent of deucravacitinib elimination by hemodialysis is small (5.4% of dose per dialysis treatment).⁵
