Efficacy of Bisphosphonates in Patients With Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis (SAPHO) Syndrome

Phase 1

Completed

• Conditions: SAPHO Syndrome
• Interventions: Drug: pamidronate disodium

• Registration Number: NCT02544659
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

This study is designed to evaluate long term efficacy of intravenous bisphosphonates for bone marrow edema in patients with SAPHO syndrome.

Detailed Description

The study will evaluate the long term efficacy at 3 days, 3 and 6 months after pamidronate disodium administered. Patients will be administered pamidronate disodium 1 mg/kg, IV, QD, for 3 days, and every 3 months (up to month 6).
