Will I have to stop taking my current medications?

Yes, you will need to stop taking all stimulant ADHD medications 5 days before starting the trial and all non-stimulant ADHD medications 21 days before starting. This is required for the entire duration of the study.

Subjects will be randomized (1:1) to their optimal dose or placebo in the 7-day, double-blind, randomization phase.
Group III: 25mg CTx-1301 (Dexmethylphenidate tablet)Active Control1 Intervention
All subjects will be titrated to their optimal dose during the dose-optimization phase. The starting dose for all subjects at Day 0 is 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.
