About this study
Official title: A Randomized, Multicenter, Parallel Group, Dose-Ranging Study to Evaluate the Safety and Tolerability of SPN-810 in Children With Attention-Deficit/Hyperactivity Disorder (ADHD) and Persistent Serious Conduct Problems
The primary objective was to evaluate the safety and tolerability of four doses of SPN-810 in children with ADHD and persistent serious conduct problems.
Read the detailed description
This will be a randomized, multicenter, parallel group, dose-ranging safety and tolerability study in children with ADHD and persistent serious conduct problems. The target subjects are healthy male or female children aged 6 to 12 years, inclusive, with a diagnosis of ADHD with persistent serious conduct problems. To determine eligibility for the study, subjects will undergo an initial screening visit. Seventy-two subjects will be randomized in the study; assuming a 17% dropout rate, it is anticipated that 60 subjects will complete the study. The study will consist of a Screening Period (within 28 days prior to the first dose administration), a Titration Period of 2 to 5 weeks, a Maintenance Period of 6 weeks, and a Safety Follow-up, which will be performed 30 days after the final study visit. The total subject duration in the study will be 16 to 19 weeks depending on the treatment group assignment. The total study duration is anticipated to be 15.5 months. A total of 72 subjects will be randomized based on weight at baseline, to 1 of 4 treatment groups.

What is being measured
The primary outcome is the main question the study is designed to answer.
The Nisonger Child Behavior Rating Form- Typical Intelligence Quotient (NCBRF-TIQ) Conduct Problem Subscale Score
The Nisonger Child Behavior Rating Form (NCBRF) is an instrument designed to assess the behavior of children with intellectual or developmental disabilities. The NCBRF-TIQ is a 66-item behavior rating form designed to assess the behavior of children and adolescents with typical development. The NCBRF is made up of three sections: I, Where raters can identify unusual circumstances that may have affected the youth's behavior; II, where positive behaviors are rated, and III, a listing of problem behaviors. There are separate Teacher and Parent versions of the form, and the NCBRF takes about 15 minutes to complete. The NCBRF is designed to be used with children and adolescents ages 3 to 16 years. The lowest score is a "0" and the highest score is "198". A higher score of the Conduct Problem Subscale score means a worse outcome. A change or negative score means improvement. Data represent the change from baseline (Visit 1) and 11 time points (Visit 2 to Visit 12).
Measured: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)
Secondary outcomes (5)
The Changes From Baseline in the CGI-S
The CGI scale was developed to provide a brief, stand-alone assessment of the clinician's view of a subject's global functioning prior to and after the administration of study medication. The severity of illness (CGI-S) is rated by the investigator on a 7-point scale with 1=Normal, 2=Borderline ill, 3=Mildly ill, 4=Moderately ill, 5=Markedly ill, 6=Severely ill, and 7=Extremely ill. Data represent the change from baseline (Visit 1) and 11 time points (Visit 2 to Visit 12). A lower overall score in subsequent testing indicates successful therapy.
Measured: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)
Clinical Global Impression - Improvement Scale (CGI-I)
Clinical Global Impression Scale. CGI-I is measured relative to the condition at the Baseline on a 7-point scale with 1=Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, and 7=Very much worse. A lower overall score in subsequential testing indicates successful treatment. Data represent the change from baseline (Visit 1) and 11 time points (Visit 2 to Visit 12).
Measured: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)
SNAP-IV ADHD Inattention
The ratings from the SNAP-IV scale are grouped into the following 3 subscales: ADHD-Inattention (items #1-9), ADHD-Hyperactivity/Impulsivity (items #10-18), and ADHD combined (items #0-18) Subscales. The symptoms are scored on a 4-point scale. Each subscale score is the average rating of the items scores for the subscale. For the inattention subscale, the scores range from 0-27, the higher the score, the worse the outcome.
A decrease in score means improvement. Data represent the change between Baseline (Visit 1) to Visit 2, Visit 4, Visit 6, Visit 10 and Visit 12.
Measured: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)
SNAP-IV Subscales ADHD Hyperactivity/Impulsivity
The ratings from the SNAP-IV scale are grouped into the following 3 subscales: ADHD-Inattention (items #1-9), ADHD-Hyperactivity/Impulsivity (items #10-18), and ADHD combined (items #1-18) Subscales. The symptoms are scored on a 4-point scale. Each subscale score is the average rating of the items scores for the subscale. For the Hyperactivity/Impulsivity subscale, the scores range from 0-27, the higher the score, the worse the outcome.
A decrease in score means improvement. Data represent the change between Baseline (Visit 1) to Visit 2, Visit 4, Visit 6, Visit 10 and Visit 12.
Measured: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)
SNAP-IV Subscales - ADHD Combined
The ratings from the SNAP-IV scale are grouped into the following 3 subscales: ADHD-Inattention (items #1-9), ADHD-Hyperactivity/Impulsivity (items #10-18), and ADHD combined (items #1-18) Subscales. The symptoms are scored on a 4-point scale. Each subscale score is the average rating of the items scores for the subscale. For the combined subscale, the scores range from 0-54, the higher the score, the worse the outcome.
A decrease in score means improvement. Data represent the change between Baseline (Visit 1) to Visit 2, Visit 4, Visit 6, Visit 10 and Visit 12.
Measured: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 16 Sep 2025). 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?
The Nisonger Child Behavior Rating Form- Typical Intelligence Quotient (NCBRF-TIQ) Conduct Problem Subscale Score (time frame: Weekly visits starting from Visit 1 (Week 1) to Visit 12 (12 weeks)). 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 NCT00626236, which also lists 1 linked publication.
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 9 Dec 2025.
