Etanercept: treatment with etanercept in addition to NSAID treatment and/or classic Disease Modifying Antirheumatic Drugs
Placebo: treatment with placebo in addition to NSAID treatment and/or classic Disease Modifying Antirheumatic Drugs
Study 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.

4. Dose modification of disease-modifying antirheumatic drugs (DMARDs) over the past 12 weeks.
5. Use of biological drugs / synthetic targeted drugs in the last 12 weeks.
6. Use of corticosteroids (orally or local injections), bisphosphonates and/or antibiotics in the last 4 weeks.
7. Any medical condition that the investigator judges to contraindicate etanercept treatment.
Primary outcome measure(s)
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.
