About this study

Official title: Assessment of Efficacy and Safety of SPN-810 for the Treatment of Impulsive Aggression (IA) in Adolescent Subjects With Attention Deficit/Hyperactivity Disorder (ADHD) in Conjunction With Standard ADHD Treatment

The purpose of this study was to evaluate the effect of SPN-810 for the treatment of impulsive aggression (IA) in adolescents diagnosed with ADHD when taken in conjunction with standard ADHD treatment.

Read the detailed description

This study was an addition to the pediatric studies (CHIME 1 and CHIME 2) to assess the efficacy and safety of SPN-810 in the improvement of impulsive aggression (IA) behaviors in adolescents with ADHD.

SPN-810 was administered in patients diagnosed with ADHD and associated features of IA, who were currently treated with an FDA-approved standard ADHD treatment and displayed persistent IA behaviors. The frequency of impulsive aggressive behaviors was assessed as a primary outcome.

What is being measured

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

  1. Effect of SPN-810 Treatment on the Frequency of Impulsive Aggression (IA) Behaviors Measured by the Impulsive Aggression Diary

    The primary efficacy endpoint was percent change (PCHT) in the frequency (unweighted score) of IA behaviors per 7 days in the treatment (titration and maintenance) period relative to the baseline period calculated over the number of days with non-missing IA diary data. PCHT was then calculated as 100 x (T - B)/B, where T and B are IA behavior frequencies per 7 days during the treatment period (from Day 2 through Visit 7, inclusive) and baseline period (Day ≤1), respectively. The IA behavior frequency per 7 days is defined as (SUM/DAY) x 7, where SUM is the total of the IA behaviors reported in the subject IA diary, and DAY is the number of days with a non-missing IA score in the subject IA diary during the specified study period.

    Measured: Daily measure from Visit 2 (Day -15) to Visit 7 (Day 36) for a total of 7 weeks

Secondary outcomes (3)
  1. Effect of SPN-810 on Impulsive Aggression (IA) Measured by Clinical Global Impression - Severity Scale (CGI-S)

    The Clinical Global Impression - Severity of Illness (CGI-S) is a single item clinician rating of clinician's assessment of the severity of IA behaviors. CGI-S was evaluated by the Investigator at each visit 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 between Baseline (Visit 3/Day 1) and four time points: Visit 4 (Day 15); Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36).

    Measured: From Baseline/Visit 3 (Day 1) to Visit 4 (Day 15), Visit 5 (Day 22), Visit 6 (Day 29), Visit 7 (Day 36)

  2. Effect of SPN810 on Retrospective-Modified Overt Aggression Scale (R-MOAS) Total Score

    R-MOAS scale gauges the severity of aggressive behavior: the frequency of the 16 behaviors is rated over the past week in 4 areas (VE, PH, PR, SE). For each open question in each area, the parent-rated the aggressive behaviors on a scale from 0 to 5 or more times. To each area corresponds a weighted category: Verbal Incidents (VE)=1, Incidents Toward Other (PH)=4, Incidents Involving Property (PR)=2 and Incidents Directed Toward Self (SE)=3. Therefore, the sum of each area yields a maximum weighted score of 20 (VE), 120 (PH), 60 (PR), and 90 (SE). The total score is the sum of the four area scores or 0-290; the higher the score, the more severe the aggressive behavior is.

    Data represent the total score change between the Baseline (Visit 3/Day 1) and four time points: Visit 4 (Day 15); Visit 5 (Day 22), Visit 6 (Day 29), and Visit 7 (Day 36).

    Measured: From Baseline/Visit 3 (Day 1) to Visit 4 (Day 15), Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36).

  3. Effect of SPN-810 on Retrospective-Modified Overt Aggression Scale (R-MOAS) Remission Rate

    The treatment effect on the R-MOAS was assessed to capture the severity of the aggressive behaviors. The remission rate was defined as percentage of subjects with a R-MOAS total score ≤ 10.

    Data represent the percentage of subjects at four time points during the treatment period: Visit 4 (Day 15); Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36).

    Measured: Visit 4 (Day 15), Visit 5 (Day 22), Visit 6 (Day 29) and Visit 7 (Day 36)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SPN-810 in people with Attention Deficit Hyperactivity Disorder, run by Supernus Pharmaceuticals, Inc. at 38 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 2 inclusion and 3 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: stopped early, as of the sponsor's last update on 24 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 38 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 20 Feb 2024). 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?

Effect of SPN-810 Treatment on the Frequency of Impulsive Aggression (IA) Behaviors Measured by the Impulsive Aggression Diary (time frame: Daily measure from Visit 2 (Day -15) to Visit 7 (Day 36) for a total of 7 weeks). 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 24 Apr 2024.
