MOA
SOTYKTU has a unique MOA that selectively targets TYK21,2
How SOTYKTU works
- TYK2 mediates multiple cytokine pathways, such as IL-23. By doing so, TYK2 impacts the production of IL-17. TYK2 is an important link between IL-23 and IL-17, key inflammatory cytokines in psoriasis3
- SOTYKTU is an oral, selective TYK2 inhibitor that disrupts this pathway1,2*†
- SOTYKTU is selective for TYK2 and has not been shown to inhibit JAK1/2/3 pathways at clinically relevant doses in in vitro assays1,2
The precise mechanism linking inhibition of TYK2 enzyme to therapeutic effectiveness in the treatment of adults with moderate-to-severe plaque psoriasis is not currently known.1
TYK2 pairs with JAK1 or JAK2 to mediate multiple cytokine pathways and transmit signals.1
* | SOTYKTU reduced psoriasis-associated gene expression in psoriatic skin in a dose-dependent manner, including reductions in IL-23 pathway- and Type I IFN-regulated genes.1 |
† | SOTYKTU reduced IL-17A, IL-19, and beta-defensin by 47% to 50%, 72%, and 81% to 84% respectively following 16 weeks of once-daily treatment.1 |
The relationship between these pharmacodynamic markers and the mechanism(s) by which SOTYKTU exerts its clinical effects is unknown.1 | |
Tyrosine kinase 2 is a member of the Janus kinase family.1 | |
IFN=interferon; IL=interleukin; JAK=Janus kinase; MOA=mechanism of action; STAT=signal transducer and activator of transcription; TYK2=tyrosine kinase 2. |
SELECT IMPORTANT SAFETY INFORMATION
Potential Risks Related to JAK Inhibition: It is not known whether tyrosine kinase 2 (TYK2) inhibition may be associated with the observed or potential adverse reactions of Janus Kinase (JAK) inhibition. In a large, randomized, postmarketing safety trial of a JAK inhibitor in rheumatoid arthritis (RA), patients 50 years of age and older with at least one cardiovascular risk factor, higher rates of all-cause mortality, including sudden cardiovascular death, major adverse cardiovascular events, overall thrombosis, deep venous thrombosis, pulmonary embolism, and malignancies (excluding non-melanoma skin cancer) were observed in patients treated with the JAK inhibitor compared to those treated with TNF blockers. SOTYKTU is not approved for use in RA.
