To test the effectiveness of an addiction-based weight loss intervention, embodied first as a smartphone app with telephone coaching (AppCoach) compared to (1) addiction model based weight-loss app alone (App) and (2) multi-disciplinary in-clinic weight loss intervention (Clinic) on weight outcomes of overweight and obese adolescents at 3, 6, 12 and 18 months post enrollment.
This is 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 LLD ≤ A4 ≤ 2.5x ULN and are on supraphysiologic doses of GC therapy (≥30 mg/day and ≤60 mg/day HCe). This will be the first study of tildacerfont to evaluate GC dose reduction. In addition, this study will characterize clinical outcomes after up to 76 weeks of treatment with tildacerfont. An optional Open-Label Extension Period will provide an open-label treatment with tildacerfont at 200 mg QD for up to 240 weeks.
