Summary

This trial tests a new drug to help kids (6-12) with ADHD in a lab classroom setting to see if it's safe and effective.

Who is the study for?
This trial is for children aged 6-12 with ADHD who are in good health and meet the DSM-5 criteria for ADHD. They must score above certain thresholds on specific ADHD scales, be able to stop current ADHD medications, understand English, and not have any significant medical conditions or psychiatric disorders that could interfere with the study.Check my eligibility
What is being tested?
The trial tests various doses of CTx-1301 (a form of dexmethylphenidate) against a placebo to see how effective and safe it is in treating pediatric ADHD within a controlled classroom setting. The goal is to find an optimal dose that improves attention without causing harm.See study design
What are the potential side effects?
Potential side effects may include typical stimulant-related issues such as trouble sleeping, decreased appetite, stomachaches, headaches, increased blood pressure and heart rate. There might also be mood swings or nervousness similar to other medications used for treating ADHD.

7Treatment groups
Experimental Treatment
Placebo Group
Group I: Experimental: 6.25mg CTx-1301 (Dexmethylphenidate tablet)Experimental Treatment1 Intervention
All subjects will be titrated to their optimal dose during the dose-optimization phase. Possible doses are 6.25mg, 12.5mg, 18.75mg, 25.0mg, 31.25mg, or 37.5mg. The starting dose for all subjects at Day 0 is 6.25mg. Each subject is expected to be on their optimal dose for 2 sequential weeks prior to the randomization phase. Subjects will be randomized (1:1) to their optimal dose or placebo in the 7-day, double-blind, randomization phase.

All subjects will be titrated to their optimal dose during the dose-optimization phase. Possible doses are 6.25mg, 12.5mg, 18.75mg, 25.0mg, 31.25mg, or 37.5mg. The starting dose for all subjects at Day 0 is 6.25mg. Each subject is expected to be on their optimal dose for 2 sequential weeks prior to the randomization phase.
