About this study
Official title: A Multicenter, Dose-Optimized, Double-Blind, Randomized, Placebo-Controlled, Crossover Study to Evaluate the Efficacy of AR11 (Amphetamine Sulfate) in Pediatric Patients (Ages 6-12) With ADHD in a Laboratory Classroom
This is a dose-optimized, randomized, double-blind, placebo-controlled crossover study in approximately 100 pediatric patients (aged 6 to 12 years) with ADHD. Eligible patients will enroll to take open-label AR11 BID and undergo dose optimization activities for 8 weeks. Patients who achieve a stable dose during the dose optimization period will continue participation and will be randomized to take double-blind medication (AR11 or placebo) orally twice daily for 1 week. At the end of each double-blind treatment period, patients will be evaluated for ADHD symptoms in a laboratory classroom setting utilizing SKAMP and PERMP assessments.

| Study group | Role | What they receive |
|---|---|---|
| AR11 (amphetamine sulfate) (1 week) - double blind | Experimental | AR11, administered orally, BID, for one week (crossover to placebo administration week 2) Receives: Drug: AR11 |

What is being measured
The primary outcome is the main question the study is designed to answer.
SKAMP-Combined Scores
Swanson, Kotkin, Agler, M-Flynn, and Pelham Scale [SKAMP]-combined scores measured during Laboratory Classroom Days. The SKAMP scale is a validated subjective measure of ADHD symptoms in a laboratory classroom, comprised of 13 items on which subjects are rated according to a 7 point scale (0=normal to 6=maximal impairment); maximum score 78. The SKAMP-combined score is obtained by summing the rating values for each of the 13 items, whereby the higher the SKAMP score, the greater the impairment.
Measured: 2 hours post-dose

The SKAMP scale is a validated subjective measure of ADHD symptoms in a laboratory classroom, comprised of 13 items on which subjects are rated according to a 7 point scale (0=normal to 6=maximal impairment); maximum score 78. The SKAMP-combined score is obtained by summing the rating values for each of the 13 items, whereby the higher the SKAMP score, the greater the impairment.
Measured: 0.75, 4, 6, 8, 10 hours post-dose
SKAMP Subscale - Attention Scores
The SKAMP scale is a validated subjective measure of ADHD symptoms. It is comprised of 13 items (grouped under the subcategories of attention, deportment, quality of work, and compliance) on which subjects are rated according to a 7-point scale (0 = normal to 6 = maximal impairment). The SKAMP-Attention subscale score is comprised of four of the 13 items with a maximum score of 24.
Measured: 0.75, 2, 4, 6, 8, and 10 hours post-dose
SKAMP Subscale - Deportment Scores
The SKAMP scale is a validated subjective measure of ADHD symptoms. It is comprised of 13 items (grouped under the subcategories of attention, deportment, quality of work, and compliance) on which subjects are rated according to a 7-point scale (0 = normal to 6 = maximal impairment). The SKAMP-Deportment subscale score is comprised of four of the 13 items with a maximum score of 24.
Measured: 0.75, 2, 4, 6, 8, and 10 hours post-dose
PERM-P Scores - Number of Problems Attempted
Permanent Product Measure of Performance (PERMP) assessments measured during Laboratory Classroom Days. The PERMP is an individualized, five-page math exam consisting of 400 problems. Subjects are instructed to complete as many math problems as possible in 10 minutes. Performance is evaluated using the number of problems attempted (maximum score = 400) and the number of problems correct (maximum score = 400).
Measured: 0.75, 2, 4, 6, 8, and 10 hours post-dose
PERM-P Scores - Number of Problems Correct
Permanent Product Measure of Performance (PERMP) assessments measured during Laboratory Classroom Days. The PERMP is an individualized, five-page math exam consisting of 400 problems. Subjects are instructed to complete as many math problems as possible in 10 minutes. Performance is evaluated using the number of problems attempted (maximum score = 400) and the number of problems correct (maximum score = 400).
Measured: 0.75, 2, 4, 6, 8, and 10 hours post-dose

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a dose-optimized, randomized, double-blind, placebo-controlled crossover study in approximately 100 pediatric patients (aged 6 to 12 years) with ADHD. Eligible patients will enroll to take open-label AR11 BID and undergo dose optimization activities for 8 weeks. Patients who achieve a stable dose during the dose optimization period will continue participation and will be randomized to take double-blind medication (AR11 or placebo) orally twice daily for 1 week. At the end of each double-blind treatment period, patients will be evaluated for ADHD symptoms in a laboratory classroom setting utilizing SKAMP and PERMP assessments.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing AR11 in people with Attention Deficit Hyperactivity Disorder (ADHD), run by Arbor Pharmaceuticals, Inc. at 7 sites 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 4 inclusion and 6 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: finished, as of the sponsor's last update on 21 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites 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?
Yes. Results are posted in the registry (first posted 19 Apr 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
SKAMP-Combined Scores (time frame: 2 hours post-dose). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01986062, which also lists 2 linked publications.
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 21 Jul 2020; AzTrials last refreshed its copy on 6 Nov 2026.
