286 patients around the world
Available in Argentina, United States, Brazil, Spain
This is a pivotal Phase 3, multicenter, randomized, double-blind, placebo-controlled study of the efficacy and safety of DMX-200 in patients with FSGS. The duration of the double-blind period per patient is estimated to be maximum of 122 weeks, a Screening and Qualification period of between 6 and 14 weeks (including a 4 week period to complete the assessments required for Screening, Titration (if required, up to 4 weeks) and, 6-weeks of Stabilization, a 104-week Treatment period, and up to a 4-week off-treatment Follow-up period.
