Eligibility Criteria
You may qualify if:
- Subjects voluntarily particpate in this clinical study and sign the informed consent form.
- Male and female patients aged 18-75 years at the time of screening (both inclusive)
- Meet the diagnosis of active Ankylosing Spondylitis(AS), have a record of radiological evidence consistent with the Modified New York Classification Criteria for ankylosing spondylitis as revised in 1984 4. Diagnosis of active AS (active AS is defined as: BASDAI \>= 4, total back pain score \>=4, and BASDAI second question spinal pain score \>=4)
You may not qualify if:
- Pregnant or lactating women.
- Active diseases that may confound the evaluation of JS005: other autoimmune inflammatory diseases (including but not limited to systemic lupus erythematosus, rheumatoid arthritis, sarcoidosis, vasculitis, etc.) or chronic pain other than ankylosing spondylitis (including but not limited to fibromyalgia, osteoarthritis, etc.).
- \. Active inflammatory bowel disease within 6 months prior to randomization. 5. Recurrent anterior uveitis or acute anterior uveitis within the last 4 weeks prior to randomization.
- \. History or evidence of active or latent tuberculosis (TB), defined as a positive interferon gamma release assay (IGRA) or purified protein derivative (PPD) at the time of screening. 7. Positive hepatitis B virus test result 8. Prior exposure to JS005 or any other biologic that directly targets IL-17 or the IL-17 receptor.
- \. use of \>= 2 TNF-α inhibitors.
