简要总结
The objective of this randomized, double-blind, placebo-controlled phase II clinical trial is to investigate the safety and efficacy of QLS12010 in subjects with moderate-to-severe rheumatoid arthritis.The main questions it aims to answer are:
• Efficacy and safety of QLS12010 in participants with rheumatoid arthritis.
Participants will be randomly allocated to four treatment groups at a 1:1:1:1 ratio to compare the efficacy and safety of different dosages of QLS12010 Capsules against the placebo.

结局指标
主要结局
Change in Disease Activity Score-C-Reactive Protein (DAS28-CRP) from Baseline at Week 12.
时间窗: 12 weeks
The DAS28-CRP score measures how active rheumatoid arthritis is. A score of 2.6 or lower indicates disease remission, while a greater score indicates more severe disease.
