Study Details

Study Description

Brief Summary

The aim of this study is to evaluate and compare the efficacy and safety of tofacitinib and methotrexate based on prednisone therapy in patients with Takayasu arteritis

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

Takayasu's arteritis (TAK), a chronic large vessel vasculitis, involves the aorta and its main branches. Glucocorticoids and immunosuppressants such as methotrexate, cyclophosphamide are common agents for TAK treatment. However, their effects for remission induction and relapse prevention are not satisfied. More effective agents for TAK treatment remain to be investigated. Tofacitinib (TOF) is a Jak inhibitor, which has been proved to be effective in multiple autoimmune diseases such as rheumatoid arthritis. Our preliminary real-world study also demonstrated a promising treatment effect of TOF in patients with TAK. But its efficacy and safety needs further verification. The present randomized controlled trial aimes to compare efficacy between methotrexate and tofacitinib in TAK treatment.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Tofacitinib

Partcipants would be given one tablet of tofacitinib (5mg per tablet), twice per day, the treatment duration will last 12 months during the whole follow-up period.

Drug: Tofacitinib
Tofacitinib 5mg twice a day for 12 months; Basic treatment with prednisone: (1) the initial dose of prednisone (or equivalent): 0.8mg/kg/day. (2) Glucocorticoids tapering: glucocorticoids is tapered after two weeks treatment and is tapered 5mg each 2 weeks to 10mg qd in the first 6 months if patients were in inactive status based on the NIH disease activity criteria. During the 6th to 12th month, glucocorticoids is tapered 2.5mg each 4 weeks until disuse if patients were in inactive status based on the NIH disease activity criteria.
Other Names:
  • TOF
  • Active Comparator: Methotrexate

    Participates would be given tablets of methotrexate (2.5mg per tablet) 15mg each week, the treatment duration will last 12 months during the whole follow-up period.

    Drug: Methotrexate
    Methotrexate (15mg each week) for 12 months Basic treatment with prednisone: (1) the initial dose of prednisone (or equivalent): 0.8mg/kg/day. (2) Glucocorticoids tapering: glucocorticoids is tapered after two weeks treatment and is tapered 5mg each 2 weeks to 10mg qd in the first 6 months if patients were in inactive status based on the NIH disease activity criteria. During the 6th to 12th month, glucocorticoids is tapered 2.5mg each 4 weeks until disuse if patients were in inactive status based on the NIH disease activity criteria.
    Other Names:
  • MTX
  • Outcome Measures

    Primary Outcome Measures

    1. The effectiveness rate after 6 months' treatment [From the enrollment to the end of 6 months]

      The effectiveness rate equals to patients who achieved this goal /patients at the end of 6 months. The effectiveness was defined as satisfying three of the following 1)-4) criteria and the 5) criteria: 1) no systemic symptoms such as weakness, weight loss, etc; 2) no new ischemic symptoms or signs; 3) normal erythrocyte sedimentation rate (ESR); 4) no new vascular progression or new lesions upon imaging; 5) GCs is tapered to 10mg qd and this dosage is maintained for 4 weeks.

    Secondary Outcome Measures

    1. The remission rate with GCs 5mg qd at the end of 12 months [From the enrollment to the the end of 12 months]

      Ratio of patients who achieved remission with GCs 5mg qd at the end of 12 months. The remission is defined as satisfying three of the following 1)-4) criteria: 1) no systemic symptoms such as weakness, weight loss, etc; 2) no new ischemic symptoms or signs; 3) normal erythrocyte sedimentation rate (ESR); 4) no new vascular progression or new lesions upon imaging. It is required that GCs 5mg qd should be maintained at least for four weeks.

    2. The remission rate with GCs 0mg qd at the end of 12 months [From the enrollment to the the end of 12 months]

      Ratio of patients who achieved remission with GCs 0mg qd at the end of 12 months. The remission is defined as satisfying three of the following 1)-4) criteria: 1) no systemic symptoms such as weakness, weight loss, etc; 2) no new ischemic symptoms or signs; 3) normal erythrocyte sedimentation rate (ESR); 4) no new vascular progression or new lesions upon imaging. It is required that GCs 0mg qd should be maintained at least for four weeks.

    3. Relapse free survival rate [From the enrollment to the the end of 12 month]

      Ratio of patients without relapse after achieving remission during the 12 months follow-up

    4. The cumulative dosage of GCs during the whole period of 12-months follow-up [From the enrollment to the the end of 12 months]

      The cumulative dosage = Sum of doses of prednisone (or equivalents) each day

    5. Side effects rate [From the enrollment to the the end of 12 months]

      Ratio of patients with side effects. All the kinds of adverse event related to the treatment and the disease itself will be recorded.
