What is being measured

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

  1. Incidence of Adverse Events During 6 Weeks of Treatment

    The percent of subjects who took at least one dose of immediate-release viloxazine (Safety Population; N) and who reported at least one Adverse Event (n). The percent is calculated by dividing "the number of subjects who reported at least one Adverse Event (n)" by "the number of subjects in the Safety Population (N)" and multiplying the product by 100. The higher the percentage, the higher the incidence in the Safety Population

    Measured: Weeks 1-6

Secondary outcomes (6)
  1. Change From Baseline in the Investigator-Rated Conners' Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (CAARS) Total Score at Week 6 (End of Study)

    The Conners' Adult ADHD Rating Scale (CAARS) is an ADHD-specific rating scale designed and validated to assess current ADHD symptomatology in adults. The CAARS consists of 30 items, including 18 items that correspond to the 18 ADHD symptoms per the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV). The 18 items are further subdivided into two subscales: Inattention (9 items) and Hyperactivity/Impulsivity (9 items). Each item is rated on a 4-point scale from 0 (not at all, never) to 3 (very much, very frequently). The sum of 18 items yields the raw Total score (range: 0 to 54; the higher the score, the more severe the ADHD symptoms). Raw score is converted to a change from baseline (CFB) score. A lower CFB score (<0) represents a better outcome.

    Measured: Baseline and Week 6

  2. Change From Baseline in the Investigator-Rated Conners' Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (CAARS) Total Score at Week 1

    The Conners' Adult ADHD Rating Scale (CAARS) is an ADHD-specific rating scale designed and validated to assess current ADHD symptomatology in adults. The CAARS consists of 30 items, including 18 items that correspond to the 18 ADHD symptoms per the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV).

Each item is rated on a 4-point scale from 0 (not at all, never) to 3 (very much, very frequently). The sum of 18 items yields the raw Total score (range: 0 to 54; the higher the score, the more severe the ADHD symptoms). Raw score is converted to a change from baseline (CFB) score. A lower CFB score (<0) represents a better outcome.

    Measured: Baseline and Week 1

  3. Change in Global Clinical Impression-Improvement (CGI-I) Score From Baseline Global Clinical Impression-Severity of Illness (CGI-S) Score at Week 1, Week 2, Week 3, Week 4, Week 5, and Week 6

    The Global Clinical Impression-Improvement (CGI-I) scale is a single item clinician-rated assessment of how much the subject's condition (symptoms) has improved, worsened, or has not changed relative to his/her baseline state prior to the beginning of treatment; it is rated on a 7-point scale from 1 to 7, where 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, 7=very much worse. The Clinical Global Impression-Severity of Illness (CGI-S) score is a single item clinician-rated assessment of the severity of subject's condition (symptoms) in relation to the clinician's total experience with patients with ADHD; it is rated on a 7-point scale with 1=Normal, not at all ill, 2=Borderline Ill, 3=Mildly Ill, 4=Moderately Ill, 5=Markedly Ill, 6=Severely Ill, 7=Among the most extremely ill patients. CGI-I scores at post-baseline visits were subtracted from CGI-S score at baseline; a change from baseline score <0 represent better outcome.

    Measured: Weeks 1, 2, 3, 4, 5, and 6

  4. Change From Baseline in the Investigator-Rated Conners' Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (CAARS) Total Score at Week 2, Week 3, Week 4, and Week 5

    The Conners' Adult ADHD Rating Scale (CAARS) is an ADHD-specific rating scale designed and validated to assess current ADHD symptomatology in adults. The CAARS consists of 30 items, including 18 items that correspond to the 18 ADHD symptoms per the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV). The 18 items are further subdivided into two subscales: Inattention (9 items) and Hyperactivity/Impulsivity (9 items). Each item is rated on a 4-point scale from 0 (not at all, never) to 3 (very much, very frequently). The sum of 18 items yields the raw Total score (range: 0 to 54; the higher the score, the more severe the ADHD symptoms). Raw score is converted to a change from baseline (CFB) score. A lower CFB score (<0) represents a better outcome.

    Measured: Baseline and Weeks 2, 3, 4, and 5

  5. Change From Baseline in the Self-rated Conners' Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (CAARS) Total Score at Week 6

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing IR Viloxazine in people with Attention-Deficit/Hyperactivity Disorder (ADHD), run by Supernus Pharmaceuticals, Inc. at 4 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 10 inclusion and 17 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 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 15 Oct 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?

Incidence of Adverse Events During 6 Weeks of Treatment (time frame: Weeks 1-6). 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 15 Oct 2024.
