About this study

Official title: A Randomized, Double-blind, Parallel, Placebo-controlled, Flexible-dose Study of ADZENYS XR-ODT™ in Children Aged 4 to Less Than 6 Years Diagnosed With Attention-deficit/Hyperactivity Disorder (ADHD)

This is a randomized, double-blind, flexible dose-titration, placebo-controlled, parallel-group study designed to evaluate the efficacy, safety, and tolerability of ADZENYS XR-ODT compared to placebo in children with ADHD.

Read the detailed description

This randomized, double-blind, flexible-dose, placebo-controlled, parallel group study is designed to evaluate the efficacy, safety, and tolerability of ADZENYS XR-ODT compared to placebo in children with ADHD. Male and female children ages 4 to less than 6 years with a diagnosis of ADHD based on Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria (combined, inattentive, or hyperactive/impulsive) will be enrolled.

A Screening/Washout Period of up to 4 weeks (Days -28 to -1), which will include washout of any current ADHD medications (if applicable), will be followed by an 8-week, Randomized, Double-blind, Flexible-dose Period during which subjects will be randomly assigned to placebo or to ADZENYS XR-ODT once daily. All subjects will start on 3.1 mg of ADZENYS XR-ODT or matching placebo. The dose for each subject will be titrated in a stepwise fashion each week from Visit 3 to Visit 8 (Weeks 1 to 6) based on efficacy and tolerability to 6.3 mg; 9.4 mg; 12.5 mg; 15.7 mg; and 18.8 mg once daily, until an optimal dose or the highest dose is reached. No subject will receive a dose higher than 18.8 mg/day. Subjects must remain on a stable dose for at least 2 weeks.

An optimal dose is one that produces a reduction from Baseline of ADHD symptoms (ADHD Rating Scale IV [ADHD-RS-IV] Preschool Version) of ≥30% and a Clinical Global Impression Severity (CGI-S) score of 1 (normal), 2 (borderline ill), or 3 (mildly ill), while maintaining a tolerable adverse event (AE) profile. Once subjects reach an optimal dose of study drug, they will continue on that dose for the remainder of the study.

During titration, if a higher dose is not tolerated, the investigator may reduce the subject's dose by 1 dose level (this may not be done after Week 6 [Visit 8] of the study).

If further dose reductions are required, the subject should be discontinued from the study. Subjects who are unable to tolerate the lowest daily dose (3.1 mg) of study drug will be discontinued from the study.

Subjects who complete the 8-week Treatment Period may be eligible to enter the long-term safety and tolerability study of ADZENYS XR-ODT (NT0202.1010). For subjects to be eligible, they must complete Visit 10 without experiencing any clinically significant AEs that would preclude further exposure to ADZENYS XR-ODT. For subjects entering Study NT0202.1010, Visit 10 of this study can be Visit 1 of Study NT0202.1010, unless more than 2 weeks have elapsed since Visit 10. A safety follow-up telephone call will be made to parents/legal guardians approximately 1 week after discontinuation of study drug for subjects who do not roll over into Study NT0202.1010.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ADZENYS XR-ODTDrug

    ADZENYS XR-ODT™ (amphetamine) is an extended-release orally disintegrating tablet approved for once-daily oral administration for the treatment of ADHD in patients 6 years and older.

  • Placebo Oral TabletDrug

    Participants in this arm will be given placebo as matching ODT once daily during the double-blind treatment period.

Study groups in NCT07169162
Study groupRoleWhat they receive
ADZENYS XR-ODTExperimentalSubjects will be assigned to receive ADZENYS XR-ODT orally disintegrating tablets in a randomized manner. Subjects will receive their dose once daily in the morning. All subjects will begin taking ADZENYS XR ODT 3.1 mg per day the morning after qualifying at Visit 2. The dose for each subject will be titrated in a stepwise fashion each week through Week 6 (Visit 8) based on the investigator's judgment of subject's clinical response (i.e., efficacy and tolerability) to 6.3 mg, 9.4 mg, 12.5 mg, 15.7 mg, up to 18.8 mg once daily, until an optimal dose or the highest dose is reached. No subject will receive a dose higher than 18.8 mg/day. Doses will comprise 1 or 2 tablets to achieve the (rounded) assigned dose. Once subjects reach an optimal dose of study drug, they will continue that dose for the remainder of the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Attention-deficit/hyperactivity disorder Rating Scale-IV Preschool Version Total Score

    Attention-Deficit/Hyperactivity Disorder Rating Scale-IV: Preschool Version (ADHD-RS-IV: Preschool Version) The ADHD-RS-IV Home and School checklists consist of the nine inattention and nine hyperactive/impulsive items that comprise the ADHD symptom criteria in the DSM-IV. Each item is rated on a four-point scale (0=never or rarely to 3=very often).

    Scores above the 93%ile are suspicious for but not diagnostic of preschool ADHD.

    Boys - Parent Inattention: 14 Hyperactivity/Impulsivity: 17 Total Score: 32/Teacher Inattention: 18 Hyperactivity/Impulsivity: 22 Total Score: 38 Girls - Parent Inattention: 12 Hyperactivity/Impulsivity: 14 Total Score: 24/Teacher Inattention: 11 Hyperactivity/Impulsivity: 13 Total Score: 24

    Measured: Visit 10/Day 56

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ADZENYS XR-ODT in people with Attention Deficit Hyperactivity Disorder, run by Aytu BioPharma, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 3 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Attention-deficit/hyperactivity disorder Rating Scale-IV Preschool Version Total Score (time frame: Visit 10/Day 56). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Oct 2025.
