Intervention model description: Mild and moderate TAK patients were divided into two groups, with 38 cases for each group at the randomized ratio 1:1, prescribed with methotrexate (15mg.qw.po) and tofacitinib (5mg.bid.po) respectively, in the presence of prednisone. After the 24 weeks of treatment, the disease remission is evaluated (primary endpoint). If the disease activity is alleviated, the strategy would be maintained for another 24weeks, otherwise, the treatment strategy would be shifted to the opposite for 24weeks. After 48 weeks, the disease remission would be evaluated once again (secondary endpoint)
Primary purpose: TREATMENT

Brief summary: Takayasu arteritis (TAK) is a rare chronic inflammatory arteritis, which lacks an effective well-accepted intervention strategy. Here we tried to classify TAK patients in 3 levels, including mild, moderate, and severe, and prescribe methotrexate and tofacitinib randomly in mild and moderate patients, to observe the relatively better treatment strategy, facilitating better intervention strategy in TAK patients.

Detailed description: The Takayasu arteritis (TAK) is a rare chronic inflammatory arteritis, which lacks effective well-accepted intervention strategy. Previous studies have revealed that methoxamine, tofacitinib, adalimumab, and tocilizumab were effective in controlling disease activity and preventing disease relapse in some TAK patients. However, we believed that different patients should be prescribed different drug combinations, i.e. personalized medicine, to obtain the optimal intervention effect.

So, here we tried to classify the TAK patients into three levels, and prescribe different drug interventions to discover the relatively better treatment strategy.

1. Patients were classified as mild, moderate and severe group according to the disease severity of TAK patients.

2. Based on the TAK patients in the ECTA cohort (Clinical trials. No: NCT03893136), we tried to compare the treatment efficacy between Tofacitinib (TOF) and methotrexate (MTX) in mild and moderate patients, with a randomized open-label study.

Other important detailed description of the study are listed as follows:

1. Basic treatment of prednisone: The initial prednisone dose is 40mg.qd.po, and maintained for 1 month. After 1 month's treatment, the dose is gradually tapered to 15mg by 5mg per 2 weeks. Subsequently, the dose is decreased to 5mg by 2.5mg per 3 months. The 5mg is the final target maintained dose. In the treatment, if the relapse occurs, the dose of prednisone returned to the last dosage. For example, if the patient gets a relapse at the dose of 15mg of prednisone, then the dose of prednisone returned to 20mg.

   The relapse of TAK is defined according to the "2018 Update of the EULAR recommendations for the management of large vessel vasculitis". Relapse includes major relapse or minor relapse. Major relapse: Recurrence of active disease with either of the following: a. Clinical features of ischemia\* (including jaw claudication, visual symptoms, the visual loss attributable to TAK, scalp necrosis, stroke, limb claudication). b. Evidence of active aortic inflammation resulting in progressive aortic or large vessel dilatation, stenosis or dissection. Minor relapse Recurrence of active disease, not fulfilling the criteria for a major relapse.
2. TOF: 5mg bid p.o.
3. MTX: 15mg qw p.o.
4. Treatment shift: if the TAK patients in the TOF group failed to reach clinical remission at the end of the 24th week, they would be shifted to MTX group starting a new round of induction and complete the rest 24-week follow-up; and vice versa.

In the follow-up, the disease remission and related markers are monitored.
