The purpose of this study is to evaluate preliminary efficacy, safety pharmacokinetic (PK) characteristics, pharmacodynamics (PD) haracteristics and immunogenicity of JS005 at different doses in Chine...
Detailed Description
This is a randomized, double-blind, placebo-controlled study. Approximately 120 patients who meet the eligibility criteria will be randomized to one of three treatment cohorts (JS005 150 mg, 300 mg, 4...
Eligibility Criteria
Inclusion
- Patients who do not meet the modified New York criteria for AS in 1984; Meet the 2009 axSpA classification criteria recommended by International Assessment Society of Axial Spondyloarthritis (ASAS): inflammatory back pain for at least 3 months; Age of onset \< 45 years; Sacroiliitis on MRI with≥ 1 axial spondyloarthritis features or HLA-B27 positive with ≥ 2 SpA features (MRI and X-ray of sacroiliac joint as confirmed by central readers).
- Objective signs of inflammation at screening: active inflammation of the sacroiliac joints on MRI and/or high sensitivity C-reactive protein (hsCRP) \> upper limit of normal without other diagnoses to explain the MRI results or elevated hsCRP.
- Active axSpA at screening and baseline: assessed by total Bath ankylosing spondylitis disease activity index (BASDAI) ≥ 4 (0-10 scale) and spinal pain ≥ 4 (according to the 0-10 NRS scale, BASDAI question #2).
- Voluntarily participate in this clinical trial and sign the informed consent form.
- Male or female aged between 18 and 65 years (both inclusive) at the time of signing informed consent. Female subjects of childbearing age are required to have a confirmed negative result of urine and/or serum pregnancy test performed within 3 days before randomization and agree to use reliable contraceptive measures during the study; Male subjects and their female partners of childbearing age must agree to use reliable contraception during the study.
- Patients meet at least one of the following: 1) have an inadequate or ineffective response to NSAIDs, 2) have been intolerant to at least one dose of NSAIDs, 3) have contraindications to NSAIDs therapy. Inadequate or ineffective response to NSAIDs is defined as no remission after continuous treatment with standard doses of at least 2 NSAIDs for a total of no less than 4 weeks and no less than 2 weeks for each NSAID.
- Patients regularly taking NSAIDs as part of their AS therapy are required to maintain a stable dose for at least 2 weeks prior to randomization.
- Patients using tumor necrosis factor α (TNFα) inhibitors must have experienced an inadequate response to the standard treatment dose for at least 3 months, or have been intolerant to TNFα inhibitors.
Exclusion
- Unable or unwilling to undergo MRI.
- Previous exposure to JS005 or any other biologic drug directly targeting IL-17 or IL-17 receptor.
- Have taken high potency analgesics (e.g., opiates of methadone, hydromorphone, morphine) within 2 weeks prior to randomization.
- Previous treatment with any intra-articular injection (e.g., glucocorticoids) within 4 weeks prior to randomization.
- Previous treatment with any biological immunomodulating agents other than the TNFα inhibitors.
- Treatment with JAK inhibitor agents within 8 weeks prior to randomization and unwilling to discontinue during the study.
