Trial Summary

What is the purpose of this trial?

This study will evaluate the efficacy, safety and pharmacokinetics of HLD200 (20 mg and 40 mg) in children aged 4 to 5 years with ADHD.

Will I have to stop taking my current medications?

The trial requires stopping certain medications before participating. You must stop using prescription medications (except allowed ones) 7 days before the baseline visit, ADHD stimulant medication 72 hours before, clonidine and guanfacine 5 days before, atomoxetine 7 days before, and MAO inhibitors 14 days before. Psychotropic medications must be stopped 14 days before the baseline visit.

What data supports the effectiveness of the drug HLD200 methylphenidate hydrochloride capsules for ADHD?

Research shows that HLD200, a delayed-release and extended-release form of methylphenidate taken in the evening, significantly improves daily functioning in children with ADHD. It helps reduce symptoms from morning through evening, with studies indicating better performance in school and at home compared to a placebo.12345

Is evening-dosed methylphenidate (HLD200) safe for humans?

In a study with children, evening-dosed methylphenidate (HLD200) was well tolerated, with no serious side effects reported compared to a placebo. Common side effects in similar treatments include decreased appetite, stomach pain, mood changes, weight loss, headache, irritability, and trouble sleeping.23467

What makes the drug HLD200 unique for treating ADHD?

HLD200 is unique because it is taken in the evening and is designed to release the medication gradually, starting to work when the person wakes up and lasting throughout the day and into the evening. This delayed-release and extended-release formulation helps manage ADHD symptoms from morning to night, unlike other treatments that are typically taken in the morning.14689

Findings from Research

In a 3-week phase 3 study involving 161 children aged 6-12 with ADHD, the evening-dosed DR/ER-MPH formulation significantly improved ADHD symptoms compared to placebo, as measured by the ADHD rating scale-IV.
DR/ER-MPH also enhanced at-home functioning in the early morning and late afternoon/evening, while being generally well tolerated, with common side effects including insomnia and decreased appetite.
Efficacy and Safety of HLD200, Delayed-Release and Extended-Release Methylphenidate, in Children with Attention-Deficit/Hyperactivity Disorder.Pliszka, SR., Wilens, TE., Bostrom, S., et al.[2018]
HLD200, a delayed-release and extended-release methylphenidate, is designed to provide therapeutic effects for children with ADHD from morning through evening, with optimal dosing predicted to be 12 hours before school.
The pharmacokinetic and pharmacodynamic models suggest that higher doses of HLD200 lead to longer durations of clinical response, which aligns with trial data showing improvements in daily functioning.
Model-Based Approach for Establishing the Predicted Clinical Response of a Delayed-Release and Extended-Release Methylphenidate for the Treatment of Attention-Deficit/Hyperactivity Disorder.Gomeni, R., Komolova, M., Incledon, B., et al.[2022]
HLD200, a delayed-release and extended-release methylphenidate, showed dose proportionality in pharmacokinetics between 20 mg and 100 mg doses, indicating consistent efficacy across different dosages.
The drug can be taken with or without food, as meal content did not significantly affect its pharmacokinetics, and there is negligible accumulation with multiple dosing, suggesting a favorable safety profile.
