A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of SPR001 (Tildacerfont) in Reducing Supraphysiologic Glucocorticoid Use in Adult Subjects with Classic Congenital Adrenal Hyperplasia

SPR001-204 will be a randomized, double-blind, placebo-controlled study that will evaluate the potential of tildacerfont to reduce GC burden in adult subjects with classic CAH who have lower limit of detection (LLD) ≤ A4 ≤ 1.5x upper limit of normal (ULN) and are on supraphysiologic doses of GC therapy. SPR001-204 will be the first study of tildacerfont to evaluate GC dose reduction. In addition, Study SPR001-204 will characterize clinical outcomes after up to 52 weeks of treatment with tildacerfont.
