What this trial studies

This clinical trial evaluates the efficacy and safety of Jitongning tablets in patients with active ankylosing spondylitis. Participants will be randomly assigned to receive either Jitongning tablets or a placebo, and their improvement will be assessed using the ASAS20 criteria. The study will also monitor other key symptoms and functions, alongside safety evaluations through regular examinations and follow-up visits. The trial aims to determine if Jitongning tablets provide superior benefits compared to a placebo.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with active ankylosing spondylitis meeting specific diagnostic criteria.

Not a fit: Patients with non-active ankylosing spondylitis or those not meeting the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new effective option for managing symptoms of ankylosing spondylitis.

How similar studies have performed: Other studies have shown promise in using traditional Chinese medicine approaches for similar conditions, but the specific use of Jitongning tablets is novel.
