Detailed Description
After screening, eligible subjects were randomly assigned in a 1:1:1:1 ratio to VDJ001 4 mg/kg group, VDJ001 6 mg/kg group, placebo group, and tocilizumab group to receive trial drug or control drug every 4 weeks. The treatment course was 12 weeks (D1, W4, W8 administration, followed up to W12).

Outcome Measures
Primary Outcome Measures
- Proportion of patients who achieved ACR20 at week 12. [12 weeks]
Proportion of patients who achieved American College of Rheumatology 20% improvement criteria (ACR20) at week 12.
Secondary Outcome Measures
- Proportion of patients who achieved ACR50, ACR70 at week 12. [12 weeks]
Proportion of patients who achieved American College of Rheumatology 50%, 70% improvement criteria at week 12.
- Proportion of patients who achieved DAS28-CRP <2.6, DAS28-ESR <2.6, DAS28-CRP <3.2, DAS28-ESR <3.2 at week 12. [12 weeks]
DAS28-CRP=0.56*(TJC28)1/2+0.28*(SJC28)1/2+0.014*GH+0.36*ln(CRP+1)+0.96; DAS28-ESR=0.56*(TJC28)1/2+0.28*(SJC28)1/2+0.014*GH+0.70*ln(ESR); In the formula, TJC28 = joint count of pressure and pain at 28 joints, SJC28 = joint count of swelling at 28 joints, GH = general health status, i.e., patient's overall assessment of disease activity, ln = natural logarithm.
- Proportion of patients who achieved a good response rate on the Clinical Disease Activity Index (CDAI) (defined as ≥50% improvement in CDAI or CDAI ≤2.8) at Week 12. [12 weeks]
CDAI=TJC28+SJC28+PGA+PhGA In the formula, TJC28 = joint counts of pressure and pain at 28 joints, SJC28 = joint counts of swelling at 28 joints,PhGA stands for physician's global visual analogue scale of disease activity in cm, and PtGA stands for patient's global visual analogue scale of disease activity in cm.
- Change in duration of morning stiffness at week 12 relative to baseline and rate of change. [12 weeks]
Morning stiffness refers to the phenomenon that the diseased joints are stiff for a longer period of time in the morning after standing still, such as the feeling of glue, which is gradually reduced after appropriate activities.
- Patient ratings of arthralgia [12 weeks]
Change in patient rating of arthralgia (PtAAP) at week 12 relative to baseline and rate of change.
- Patient's overall assessment of the condition [12 weeks]
Patient's overall assessment of the condition (PtGA) at week 12 change from baseline and rate of change.
- Physician's Global Assessment of Condition [12 weeks]
Change in Physician's Global Assessment of Condition (PhGA) relative to Baseline and Rate of Change at Week 12.
- Patient Health Assessment Questionnaire [12 weeks]
Change in Patient Health Assessment Questionnaire (HAQ-DI) Score Relative to Baseline and Rate of Change at Week 12.
- Health Status Questionnaire (SF-36) [12 weeks]
Change from baseline in Week 12 Health Status Questionnaire (SF-36) scores and rate of change.
- Functional Assessment of Chronic Illness Therapy-Fatigue Scale [12 weeks]
Change from baseline and rate of change in Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-F) score at week 12.
