A Phase 3, randomized, double-blind, placebo-controlled, multi-center, fixed-dose, parallel-group efficacy and safety study in a pediatric population (6-17) with Attention-Deficit/Hyperactivity Disorder (ADHD) using CTx-1301 (d-MPH). The study will be comprised of a screening period, a double-blind randomized phase, and a safety follow-up visit.
A Phase 3, double-blind, randomized, placebo-controlled, multi-center, fixed-dose, parallel group efficacy and safety study in pediatrics (6-17) with ADHD diagnosis confirmed by an ADHD-RS-5 score of at least 28 and CGI-S score of at least 4 (moderately ill) at screening. The study will be comprised of a screening period, a double-blind randomized phase, and a safety follow-up visit.
The Study will be comprised of 3 periods:
Subjects will participate in the study as outpatients for up to approximately 10 weeks (including screening); a 30-day screening period, a 5-week double-blind randomized period, and a 1-week follow-up safety visit.
Completion of the primary study is defined as LSLV at Visit 9.
Subjects will be randomized at baseline to CTx-1301 or placebo (CTx-1301 18.75 mg, CTx-1301 25 mg, CTx-1301 37.5 mg, or placebo). Starting dose for subjects randomized to active treatment is 12.5 mg. These subjects will then be titrated up to their assigned fixed dose (18.75, 25, or 37.5 mg) for the last two weeks of the study period. Subjects randomized to placebo will receive placebo treatment for the full 5 weeks of the study.
Sparse PK sampling will be conducted after a single dose and at steady state from the patient population with special attention given to the time the sample is obtained post-dose. These analyses will inform strategies that manage dosing and detail administration for a given subpopulation, planned subsequent studies, and support labeling.

Of the 168 screened subjects, 103 subjects were randomized and received treatment in the study, with a similar number of subjects in each treatment group.
Although approximately 385 subjects were expected to enroll in the study, the study was completed with 103 subjects enrolled after an agreement was reached with FDA on the requirements necessary for filing an NDA for CTx-1301. Subjects were recruited at 24 sites from August 1, 2023 to December 13, 2023.

| BMI Z-Score | BMI Z-scores were calculated using the CDC source code SAS program. BMI z-scores for children measure how a child's BMI compares to to other children of the same age and sex, indicating if they are underweight, healthy, overweight, or obese based on standard deviations (SD) from the average (z-score of 0). Positive scores are above average (greater than or equal to 1 SD for overweight, greater than or equal to 2 SD for obesity), and negative scores are below average (less than or equal to -2 SD for thinness). | Mean | Standard Deviation | Z-Score |
