Active Clinical Trials (As of Q1 2023)
- Total trials: 45
- Phases:
- Phase 1: 5 trials
- Phase 2: 15 trials
- Phase 3: 25 trials
- Focus areas:
- New formulations and delivery methods, including long-acting injectables.
- Expanded indications such as irritability in autism spectrum disorder (ASD), treatment-resistant depression, and Tourette syndrome.
- Pharmacokinetic and pharmacodynamic studies.
- Safety and efficacy in pediatric populations, with several Phase 3 trials in ADHD and ASD.
Notable Trials
