About this study

An observational, ambispective cohort to learn about the disease progression of axial spondyloarthritis (axSpA) according to the changes from baseline in measures of disease activity, function, and imaging.

Read the detailed description

This is an observational cohort study of Chinese patients (≥18 years of age) diagnosed with axSpA. Patients are followed at 4-6 month intervals. Data will be collected at baseline and at every follow-up time points. Primary outcomes are the structural damage measured with imaging(Conventional radiography, low-dose CT and MRI) and the disease activity measured with the Ankylosing Spondylitis Disease Activity Scale (ASDAS) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Secondary outcomes are inflammatory markers, Bath ankylosing spondylitis functional index (BASFI) and Bath ankylosing spondylitis metrology index (BASMI).

Medical subject headings
Axial Spondyloarthritis, Spondylitis, Ankylosing

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. BASFI

    The Bath Ankylosing Spondylitis Functional Index (BASFI) is a self-administered instrument comprising 10 items. The first 8 items assess functional activities (e.g., bending, reaching, climbing), while items 9 and 10 assess the patient's ability to cope with daily life and the impact of morning stiffness, respectively. Each item is scored on a 10 cm visual analog scale (or numerical rating scale), and the final score is the mean of the 10 items, ranging from 0 (best function) to 10 (worst function)

    Measured: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.

  2. Modified stoke ankylosing spondylitis spinal score (mSASSS)

    The mSASSS is a valid and widely used method for assessing radiographic progression in AS, correlating with worsening measures of disease signs and symptoms, spinal mobility and physical function.

    Measured: 2-year interval

  3. Anterior uveitis

    The occurrence of anterior uveitis episodes during the disease course in patients with axSpA

    Measured: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.

Secondary outcomes (5)
  1. ASDAS-CRP

    ASDAS-CRP=0.12 x back pain+0.06 x duration of morning stifness +0.11 x patient global+0.07 x peripheral pain/swelling +0.58xIn(CRP+1) The result of the calculation is the ASDAS-CRP score, which is used to classify the disease activity level. Generally, a score of <1.3 indicates inactive disease, 1.3 - 2.1 indicates low disease activity, 2.1 - 3.5 indicates moderate disease activity, and >3.5 indicates high disease activity.

    Measured: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.

  2. ASDAS-ESR

    ASDAS-ESR=0.08 x back pain +0.07 x duration of morning stiffness + 0.11 x patient global + 0.09 x peripheral pain/swelling +0.29x√(ESR) The calculated score is used to determine the disease activity level. Typically, a score of <1.3 suggests inactive disease, 1.3 - 2.1 indicates low disease activity, 2.1 - 3.5 represents moderate disease activity, and >3.5 means high disease activity.

    Measured: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.

  3. BASDAI

    BASDAI is a validated self assessment tool used to determine disease activity i. Utilizing a Visual Analog Scale (VAS) of 0-10 (0=none and 10=very severe) participant's answered 6 questions measuring discomfort, pain and fatigue. The final BASDAI score averages the individual assessments for a final score range of 0-10.

    Measured: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.

  4. BASMI

    The Bath Ankylosing Spondylitis Metrology Index (BASMI) is a composite index derived from five clinical measurements of spinal and hip mobility: cervical rotation, tragus-to-wall distance, lumbar side flexion, lumbar flexion (modified Schober), and intermalleolar distance . Each component is scored on a scale from 0 to 10, and the total score (0-10, with 10 indicating the most severe impairment) is the mean of these five scores.

    Measured: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.

  5. The Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system.

    The Spondyloarthritis Research Consortium of Canada (SPARCC) developers have created the SPARCC MRI scoring methods to assess inflammatory activity in patients with SpA.

    Measured: From enrollment to 16 weeks,1 year; after 1year on a an average of 6 months until study completion.

Questions about this trial

What is this clinical trial studying?

An observational study of Axial Spondyloarthritis and Ankylosing Spondylitis (AS), run by China-Japan Friendship Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact weiping kong (0086-10-13611038252, kongweiping75@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BASFI (time frame: From enrollment to 16 weeks, 28 weeks, 1 year; after 1year on a an average of 6 months until study completion.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026.
