Open-label Safety Trial of Intravenous Neridronic Acid in Subjects With Complex Regional Pain Syndrome (CRPS)
In Brief
A Phase 3 clinical trial evaluating Neridronic acid for Complex Regional Pain Syndrome. Completed, enrolled 580 participants across 46 sites in 2 countries.
Detailed Summary
The aim of this trial was to investigate the safety of intravenous neridronic acid in patients with complex regional pain syndrome (CRPS). The trial was divided into 3 periods: a 60-day enrollment period, a treatment period consisting of 4 infusions over 10 days, and a follow-up period of approximately 50 weeks (with visits at Week 2, Week 6, Week 12, Week 26, Week 39, and Week 52).
