Otsuka Gains FDA Nod for First-in-Class ADHD Drug SIMTRIYO

  • Otsuka's SIMTRIYO (centanafadine) received FDA approval for ADHD treatment in adults and pediatric patients aged 6+.
  • SIMTRIYO is the first norepinephrine, dopamine, serotonin reuptake inhibitor (NDSRI) approved for ADHD.
  • Approval based on four Phase 3 trials showing statistically significant symptom reduction vs. placebo.
