- Brief Summary
The study includes adult patients with SAPHO syndrome (ORPHA: 793), meeting the modified classification criteria according to Kahn (2003), with the ineffectiveness of standard treatment (patient's global assessment of the disease on the VAS scale greater than or equal to 4 cm with accompanying pain on the VAS scale greater than or equal to 4 cm) treated with non-steroidal anti-inflammatory drugs in a stable dose for at least 4 weeks and/or classical disease-modifying antirheumatic drugs in stable doses for at least 12 weeks.

- Primary Outcome Measures
Name Time Method Change in the scope of disease activity as assessed by the patient- a decrease in the overall disease activity on the Visual Analogue Scale by min. 50 percent and a decrease in pain assessed by the patient on the Visual Analogue Scale by min. 50 percent 12 weeks (day 85) Change in the scope of disease activity as assessed by the patient - a decrease in the overall disease activity as assessed by the patient on the Visual Analogue Scale by min. 50 percent after 12 weeks from randomization day and a decrease in pain assessed by the patient on the Visual Analogue Scale by min. 50 percent after 12 weeks from randomization day. The minimum value is - 0, and the maximum value is - 100 mm. The higher scores mean a worse outcome. A decrease by a minimum of 50 percent means a better outcome.
- Secondary Outcome Measures
Name Time Method Change in physician-assessed disease activity at 4, 8 and 12 week Improvement in physician-assessed disease activity - a minimum 50 percent decrease in physician-assessed overall disease activity on the Visual Analogue Scale from the randomization score at 4, 8 and 12 weeks. The minimum value is - 0, and the maximum is - 100 mm. The higher scores mean a worse outcome. A decrease by a minimum of 50 percent means a better outcome.
Change in the C-reactive Protein from Randomization Day Score at Weeks 4, 8 and 12 Change in C-reactive Protein from Randomization Day Score at Weeks 4, 8 and 12. A decrease in C-reactive Protein means improvement.
Change in the Erythrocyte Sedimentation Rate from Randomization Day Score at Weeks 4, 8 and 12 Change in the Erythrocyte Sedimentation Rate Score from Randomization Day Score at Weeks 4, 8 and 12. A decrease in the Erythrocyte Sedimentation Rate Score means improvement.
a decrease in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score of at least 50 percent after 4, 8 and 12 weeks a decrease in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score of at least 50 percent from the Randomization Day Score at weeks 4, 8, and 12 was achieved (applies to patients with axial involvement). The minimum value is 0, the maximum value is 10. A decrease by a minimum of 50 percent means a better outcome.
Change in the Work Productivity and Activity Impairments (WPAI) from the Randomization Day Score after 4, 8 and 12 weeks Change in the Work Productivity and Activity Impairments (WPAI) from the Randomization Day Score after 4, 8 and 12 weeks. WPAI contains four domains. For each domain, the minimum value is 0 percent, and the maximum is 100 percent. Decreased Work Productivity and Activity Impairments (WPAI) Score means improvement.
status of remission- Ankylosing Spondylitis Disease Activity Score (ASDAS- C-reactive protein) below 1.3 after 4, 8 and 12 weeks status of remission - Ankylosing Spondylitis Disease Activity Score (ASDAS- C-reactive protein) below 1.3 - after 4, 8 and 12 weeks from randomization day (applies to patients with axial involvement). A score below 1.3 means a better outcome.
decrease in the Dermatology Life Quality Index (DLQI) by at least 50 percent from the result on the day of randomization after 4, 8 and 12 weeks In patients with severe acne - a decrease in the Dermatology Life Quality Index (DLQI) by at least 50 percent from the result on the day of randomization after 4, 8 and 12 weeks. The minimum value is 0, the maximum value is 30. The decrease by a minimum of 50 percent means a better outcome.
decrease in Body Surface Area (BSA) index by a minimum of 50 percent from the score on the day of randomization after 4, 8 and 12 weeks after 4, 8 and 12 weeks For patients with psoriasis: decrease in Body Surface Area (BSA) index by a minimum of 50 percent from the score on the day of randomization after 4, 8 and 12 weeks. The minimum value is 0 percent, and the maximum value is 100 percent. The decrease by a minimum of 50 percent means a better outcome.
decrease in the Dermatology Life Quality Index (DLQI) by a minimum of 50 percent after 4, 8 and 12 weeks For patients with psoriasis: decrease in the Dermatology Life Quality Index (DLQI) by a minimum of 50 percent from the score on the day of randomization after 4, 8 and 12 weeks. The minimum value is 0, the maximum value is 30. The decrease by a minimum of 50 percent means a better outcome.
Occurrence of the patient acceptable symptom state (PASS score) after 4, 8 and 12 weeks Occurrence of the patient acceptable symptom state (PASS score) after 4, 8 and 12 weeks from randomization day. Possible answer- "yes" or "no", with "yes" means a better outcome.
Change in patient-assessed disease activity after 4 and 8 weeks Change in patient-assessed disease activity - a minimum 50 percent decrease in patient-assessed Visual Analogue Scale overall disease activity from the randomization score at weeks 4 and 8 and a minimum 50 percent decrease in patient-assessed Visual Analogue Scale pain from the score on daily basis randomization after 4 and 8 weeks. The minimum value is - 0, and the maximum is - 100 mm. The higher scores mean a worse outcome. A decrease by a minimum of 50 percent means a better outcome.
Occurrence of partial remission after 4, 8 and 12 weeks Occurrence of partial remission - complete resolution of osteoarticular or skin symptoms in the patient's assessment - after 4, 8 and 12 weeks from randomization day
decrease in Ankylosing Spondylitis Disease Activity Score (ASDAS- C-reactive protein) ≥1.1 after 4, 8 and 12 weeks In patients with axial involvement, a decrease in Ankylosing Spondylitis Disease Activity Score (ASDAS- C-reactive protein) ≥1.1 from the Randomization Day Score at weeks 4, 8, and 12. The minimum value is 0, the maximum value is infinity. A decrease means a better outcome.
Occurrence of remission after 4, 8 and 12 weeks Occurrence of remission - complete resolution of osteoarticular and skin complaints in the patient's assessment - after 4, 8 and 12 weeks from randomization day
Change in quality of life on the Short Form-36 health survey at 4, 8 and 12 weeks Change in quality of life on the Short Form -36 (SF-36) health survey from the score on the day of randomization at 4, 8 and 12 weeks. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability.
decrease in the Bath Ankylosing Spondylitis Functional Index (BASFI) by a minimum of 50 percent after 4, 8 and 12 weeks a decrease in the Bath Ankylosing Spondylitis Functional Index (BASFI) by a minimum of 50 percent compared to the result on the day of randomization after 4, 8 and 12 weeks (applies to patients with axial involvement). The minimum value is 0, the maximum value is 10. A decrease by a minimum of 50 percent means a better outcome.
