This is a 24-week, single-center, randomized, open-label trial conducted by Peking Union Medical College Hospital. The aim of this study is to assess the efficacy and safety of deucravacitinib in adult patients with relapsing TAK in comparison to patients treated with TNF inhibitor (TNFi), the most well-recognized therapeutic choice of non-glucocorticoid immunosuppressive for patients with relapsed or refractory TAK.
Background:
The majority of patients with TAK experience relapses, and some patients fail to respond adequately to current medications used for treatment of TAK. There is an urgent unmet need to identify novel therapies to effectively treat TAK. Th-17 and Th-1 cells, and their related cytokines IL-12, IL-23, IL-17, and type I interferon have all been reported to play a role in the pathogenesis of TAK. Tyrosine kinase 2 (TYK2) mediates signaling transduction between these key cytokines and immune cells. Therefore, blocking TYK2 signaling may downregulate potential pathogenic pathways in TAK, and may be a therapeutic alternative. No study has investigated the effectiveness of agents targeting TYK2 in the treatment of TAK so far. In the present study, we aim to investigate whether deucravacitinib, an oral, selective, allosteric inhibitor of TYK2, is effective and safe for patients with relapsed TAK.
Objectives:
To assess the efficacy and safety of deucravacitinib in adult patients with relapsing TAK in comparison to patients treated with TNF inhibitor (TNFi), the most well-recognized therapeutic choice of non-glucocorticoid immunosuppressive for patients with relapsed or refractory TAK.
Overall Design:
This is a 24-week, single-center, randomized, open-label trial conducted by Peking Union Medical College Hospital. Patients enrolled into the study are randomly assigned (in a 1:1 ratio, 25 patients in each group) to receive deucravacitinib or adalimumab (a TNFi). Patients are followed for efficacy and safety at month 1, month 3, and month 6. Adverse events/Serious adverse events are assessed and recorded at each visit.
78 studies on the registry are indexed under Takayasu Arteritis; 32 are open to participants now.
This study's planned enrollment of 50 is close to the median of 50 across 37 interventional studies indexed under Takayasu Arteritis.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Patients randomly assigned to the deucravacitinib treatment group are required to take the deucravacitinib tablets 6mg orally once daily on an empty stomach or after a meal during D1-D168, and orally take the study drug deucravacitinib with warm water. It is forbidden to drink water from 1 h before administration to 1 h after administration (except for administration of water) and fasting within 1 h after administration. Continuous treatment for 168 days or subject discontinuation criteria were met. The time of dose administration is called "0" hour. Subjects who miss a study medication on one day are not allowed to take a supplement to compensate but should take the next dose.
Drug: Deucravacitinib
Participants assigned to the adalimumab treatment group receive adalimumab 40mg by subcutaneous injection every 2 weeks during D1-D168. Adalimumab is administered for 24 weeks unless the discontinuation criteria are met.
Drug: Adalimumab
Deucravacitinib is a new, oral, selective, allosteric inhibitor of TYK2. It was first approved in the United States on 09-Sep-2022 for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy.
TNFα inhibitors have already been used in TAK treatment. Several retrospective studies have demonstrated the treatment effects of these agents in patients with TAK, including disease remission, GC tapering and vascular inflammation control. According to the ACR and EULAR guidelines, TNFis are recommended to be considered in cases of relapsing or refractory TAK. These agents (including adalimumab) are the most frequently analyzed therapeutic modalities in recent studies of TAK.
