Background: The Micronutrients for Attention-Deficit/Hyperactivity Disorder in Youth (MADDY) study evaluated the efficacy and safety of a multinutrient formula for children with ADHD and emotional dysregulation. The post-RCT open-label extension (OLE) compared the effect of treatment duration (8 weeks vs 16 weeks) on ADHD symptoms, height velocity, and adverse events (AEs). Methods: Children aged 6–12 years randomized to multinutrients vs. placebo for 8 weeks (RCT), received an 8–week OLE for a total of 16 weeks. Assessments included the Clinical Global Impression-Improvement (CGI-I), Child and Adolescent Symptom Inventory-5 (CASI-5), Pediatric Adverse Events Rating Scale (PAERS), and anthropometric measures (height and weight). Results: Of the 126 in the RCT, 103 (81%) continued in the OLE. For those initially assigned to placebo, CGI-I responders increased from 23% in the RCT to 64% in the OLE; those who took multinutrients for 16 weeks increased from 53% (RCT) to 66% responders (OLE). Both groups improved on the CASI-5 composite score and subscales from week 8 to week 16 (all p–values < 0.01). The group taking 16 weeks of multinutrients had marginally greater height growth (2.3 cm) than those with 8 weeks (1.8 cm) (p = 0.07). No difference in AEs between groups was found. Conclusion: The response rate to multinutrients by blinded clinician ratings at 8 weeks was maintained to 16 weeks; the response rate in the group initially assigned to placebo improved significantly with 8 weeks of multinutrients and almost caught up with 16 weeks. Longer time on multinutrients did not result in greater AEs, confirming an acceptable safety profile. [ABSTRACT FROM AUTHOR]
