티로신 키나아제 2(TYK2) 억제제 시장 - 표적 집단, 경쟁 구도, 시장 예측(2034년)

Key Highlights:

• Tyrosine Kinase 2 (TYK2) inhibitors are effective treatments for psoriasis, psoriatic arthritis, hidradenitis suppurativa, Inflammatory Bowel Disease (IBD), dermatomyositis, Crohn's disease, Systemic Lupus Erythematosus (SLE), ulcerative colitis, and other indications.
• The only TYK2 inhibitor approved to date is Bristol-Myers Squibb's SOTYKTU (deucravacitinib), which received FDA approval for the treatment of moderate-to-severe plaque psoriasis in September 2022.
• Market size of SOTYKTU was USD 190 million in the US, in 2024, with a 32% year-over-year increase.
• Several companies, including Priovant Therapeutics (brepocitinib), Alumis (ESK-001), Galapagos (GLPG366), Takeda (zasocitinib), and others are engaged in the development of TYK2 inhibitors.
• In March 2025, Alumis and Kaken Pharmaceutical entered into a collaboration and licensing agreement to develop, manufacture, and commercialize ESK-001 for dermatology indications in Japan, with the option to expand the license to include rheumatological and gastrointestinal diseases.
• In December 2024, Bristol Myers Squibb announced results from the POETYK PsA-1 (IM011-054) and POETYK PsA-2 (IM011-055) Phase III trials, which assessed the efficacy and safety of SOTYKTU (deucravacitinib) in adults with active psoriatic arthritis.
• Overall, this is an exciting class that holds great potential for the development of treatment for autoimmune disorders and other indications. The maturation of current studies over the next few years will lead to a better understanding of TYK2 inhibitors and define their role in the therapy of autoimmune indications.

Tyrosine kinase 2 (TYK2) Inhibitors Understanding and Treatment Algorithm

Tyrosine kinase 2 (TYK2) Inhibitors Overview

TYK2 is a member of the Janus kinase (JAK) family. It is an important mediator in pro-inflammatory signaling, implicated in both innate and adaptive immune systems. Activation of TYK2 is believed to be integral to cellular processes that contribute to the development and progression of autoimmune disorders. Selective targeting of TYK2 may reduce the number of adverse events as compared to non-selective JAK inhibitors. TYK2 inhibitors are a class of drugs that block the function of TYK2, an enzyme involved in the body's immune system and associated with inflammation. By inhibiting TYK2, these inhibitors aim to reduce inflammation and its associated symptoms. TYK2 inhibitors are being explored for the treatment of various autoimmune diseases, including psoriasis, psoriatic arthritis, IBD and others.

Tyrosine Kinase 2 (TYK2) Inhibitors Market Overview

In recent years, there has been a growing interest in the exploration of TYK2 inhibitors for a variety of inflammatory disorders, encompassing psoriasis, psoriatic arthritis, hidradenitis suppurativa, IBD, dermatomyositis, SLE, Crohn's disease, and other indications.

Tyrosine Kinase 2 (TYK2) Inhibitors Epidemiology

The epidemiology chapter of TYK2 inhibitors in the report provides historical as well as forecasted epidemiology segmented as total cases in selected indications for TYK2 inhibitors, total eligible patient pool in selected indications for TYK2 inhibitors, and total treated cases in selected indications for TYK2 inhibitors in the 7MM covering the United States, EU4 (Germany, France, Italy, and Spain), and the United Kingdom, and Japan from 2020 to 2034.

• The diagnosed prevalent cases of SLE in 7MM in 2024 were nearly 1,053,700.
• In the US, plaque psoriasis is estimated to manifest in 2-3% of the adult population, with moderate-to-severe plaque psoriasis developing in approximately 20% of patients with plaque psoriasis.
• Among the EU4 and the UK, Germany accounted for the highest number of cases of hidradenitis suppurativa, followed by the UK and the lowest number of cases in Spain in 2024.
• Japan accounted for nearly 74,150 diagnosed prevalent cases of Crohn's disease in 2024.

Marketed Tyrosine Kinase 2 (TYK2) Inhibitors

SOTYKTU (deucravacitinib): Bristol-Myers Squibb

SOTYKTU is a selective, allosteric inhibitor of TYK2. TYK2 is a member of the JAK family. SOTYKTU binds to the regulatory domain of TYK2, stabilizing an inhibitory interaction between the regulatory and the catalytic domains of the enzyme. This results in allosteric inhibition of receptor-mediated activation of TYK2 and its downstream activation of Signal Transducers and Activators of Transcription (STATs) as shown in cell-based assays. Janus kinases function as pairs of homo- or heterodimers in the JAK-STAT pathways. TYK2 pairs with JAK1 to mediate multiple cytokine pathways and also pairs with JAK2 to transmit signals as shown in cell-based assays. 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.

The therapy is approved for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy.

Emerging Tyrosine Kinase 2 (TYK2) Inhibitors

ESK-001: Alumis

ESK-001 is a TYK2 inhibitor that reduces signaling through several cytokine receptors including receptors for interleukin (IL)-23, and type 1 interferon. ESK-001 has the potential to reduce SLE disease activity by interfering with pro-inflammatory pathways known to be involved in the pathogenesis of SLE. It is being evaluated in Phase II.

Brepocitinib: Priovant Therapeutics

Priovant's lead molecule is brepocitinib, an oral once-daily dual inhibitor of TYK2 and JAK1. By selectively inhibiting both TYK2 and JAK1, brepocitinib is optimized to suppress signaling of a wide range of TYK2- and JAK1-dependent cytokines linked to autoimmunity, including type I and type II interferon, IL-6, IL-12, and IL-23.

Priovant is developing brepocitinib across multiple severe autoimmune diseases. The company is currently running the VALOR Study, a fully enrolled single registrational Phase III trial evaluating brepocitinib in dermatomyositis patients, with top-line results expected in 2025. The company also recently initiated the Phase III CLARITY Study of brepocitinib in Non-infectious Uveitis (NIU), following successful results from the Phase II NEPTUNE Study. Priovant plans to initiate a Phase II study of brepocitinib in cutaneous sarcoidosis in 2025.

Tyrosine Kinase 2 (TYK2) Inhibitors Market Outlook

The global TYK2 inhibitor market is expected to witness substantial growth in the coming years, driven by the increasing prevalence of autoimmune diseases, robust clinical pipeline activity, and expanding regulatory approvals.

Several key players, including Takeda, Alumis, Priovant Therapeutics, and others, are involved in developing drugs for TYK2 inhibitors such as Crohn's disease, psoriasis, dermatomyositis, and others, respectively. Overall, this is an exciting new class with great potential for development. The maturation of current studies over the next few years will lead to a better understanding of TYK2 inhibitors and define their role in autoimmune indications.
