Brief summary
To assess the efficacy and safety of loxoprofen sodium hydrogel patch (LX-P) versus loxoprofen sodium tablet (LX-T) in patients with active ankylosing spondylitis(AS). The trial includes 70 patients who are randomly assigned to either the LX-P group (LX-P 100 mg per day) or LX-T group (LX-T 60 mg t.i.d.) for 4 weeks.
Detailed description
This is a 4-week randomized, open-label trial to investigate the efficacy and safety of loxoprofen sodium hydrogel patch (LX-P) versus loxoprofen sodium tablet (LX-T) in patients with active ankylosing spondylitis(AS). The trial includes 70 patients who are randomly assigned to either the LX-P group (LX-P 100 mg per day) or LX-T group (LX-T 60 mg t.i.d.) for 4 weeks.

Primary
| Measure | Time frame | Description |
|---|---|---|
| the proportions of patients reaching Assessment in Ankylosing Spondylitis 20% response (ASAS20) | week 4 | ASAS20 was defined as an improvement of ≥20% and absolute improvement of ≥1 unit (0-10-cm VAS) from baseline in ≥3 of the following 4 domains (and absence of deterioration in any domain): patient's global assessment of disease activity (PTGA), pain assessment (mean of total and nocturnal pain scores), Bath Ankylosing Spondylitis Functional Index (BASFI), and clinical inflammation (mean of 2 morning stiffness-related scores on the BASDAI) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| ASAS5/6 response | week 4 | defined as 20% improvement in 5 of the following 6 domains: PTGA, pain assessment, BASFI, clinical inflammation, spinal mobility, and C-reactive protein (CRP) |
| ASAS20 response | week 2 | ASAS20 was defined as an improvement of ≥20% and absolute improvement of ≥1 unit (0-10-cm VAS) from baseline in ≥3 of the following 4 domains (and absence of deterioration in any domain): patient's global assessment of disease activity (PTGA), pain assessment (mean of total and nocturnal pain scores), Bath Ankylosing Spondylitis Functional Index (BASFI), and clinical inflammation (mean of 2 morning stiffness-related scores on the BASDAI) |
