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.

| after 4 and 8 weeks |
| Occurrence of remission | Occurrence of remission - complete resolution of osteoarticular and skin complaints in the patient's assessment - after 4, 8 and 12 weeks from randomization day | after 4, 8 and 12 weeks |
| Occurrence of partial remission | 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 | after 4, 8 and 12 weeks |
| Occurrence of the patient acceptable symptom state (PASS score) | 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. | after 4, 8 and 12 weeks |
| Change in physician-assessed disease activity | 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. | at 4, 8 and 12 week |
| Change in the C-reactive Protein from Randomization Day Score | Change in C-reactive Protein from Randomization Day Score at Weeks 4, 8 and 12. A decrease in C-reactive Protein means improvement. | at Weeks 4, 8 and 12 |
| Change in the Erythrocyte Sedimentation Rate from Randomization Day Score | 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. | at Weeks 4, 8 and 12 |
| Change in quality of life on the Short Form-36 health survey | 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. | at 4, 8 and 12 weeks |
| Change in the Work Productivity and Activity Impairments (WPAI) from the Randomization Day Score | 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. | after 4, 8 and 12 weeks |
| decrease in Ankylosing Spondylitis Disease Activity Score (ASDAS- C-reactive protein) ≥1.1 | 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 percent, and the maximum value is 100 percent. The decrease by a minimum of 50 percent means a better outcome. | after 4, 8 and 12 weeks |
| decrease in the Dermatology Life Quality Index (DLQI) by a minimum of 50 percent | 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. | after 4, 8 and 12 weeks |
