Trial Summary

What is the purpose of this trial?

This trial aims to test the safety and tolerability of a daily ADHD medication in children and teens aged 4-17. The medication releases its effects slowly over the day to help manage symptoms consistently. HLD200 is a form of methylphenidate designed to provide benefits from morning until evening.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have started, changed, or stopped psychological treatments for ADHD in the last 30 days, you may not be eligible to participate.

What data supports the effectiveness of the drug Centanafadine Hydrochloride for ADHD?

Research shows that Centanafadine, which affects brain chemicals like norepinephrine, dopamine, and serotonin, has been tested in adults with ADHD and found to be effective in improving symptoms in phase 2 and phase 3 studies.12345

Is Centanafadine safe for treating ADHD in adults?

Findings from Research

Centanafadine sustained-release (SR) significantly reduced ADHD symptoms in adults, with a mean decrease of 21.41 points on the ADHD Rating Scale-IV after 4 weeks of treatment in a phase 2a study with 41 participants.
The phase 2b study with 85 participants showed that centanafadine-SR was effective compared to placebo, with improvements seen as early as week 1, and was generally well tolerated at doses up to 400 mg, with only mild to moderate side effects reported.

Centanafadine, a medication that inhibits the reuptake of norepinephrine, dopamine, and serotonin, has shown significant efficacy in reducing ADHD symptoms in adults, with notable improvements in the Adult ADHD Investigator Symptom Rating Scale after 42 days of treatment.
The studies demonstrated a low overall rate of treatment-emergent adverse events, indicating that centanafadine is generally safe, with only a slight increase in adverse events at higher doses and low incidences of serious side effects.

The safety profile of ADHD medications is not fully understood, with concerns about both older and newer medications potentially causing serious adverse effects, including sudden cardiac death and suicidality.
A review by the European Network for Hyperkinetic Disorders highlighted that while some adverse effects may be minimal or similar to risks in untreated individuals, further research is needed to clarify the safety risks associated with ADHD medications.
