About this study

Official title: A Multicenter, Fixed-Dose, Double-Blind, Randomized Study to Evaluate the Efficacy and Safety of AR19 (Amphetamine Sulfate) in Adult Subjects (Ages 18-55) With Attention Deficit Hyperactivity Disorder (ADHD)

The purpose of the AR19.004 study is to assess the efficacy of AR19 compared to placebo using the Adult ADHD Investigator Symptom Rating Scale (AISRS)

Read the detailed description

This is a randomized, fixed-dose, double-blind, multicenter trial to investigate the safety and efficacy of AR19 in the treatment of ADHD in adults from 18 through 55 years of age. Safety parameters and therapeutic effect will be evaluated throughout the trial. A target of 312 subjects is set for enrollment. Once subjects are determined to meet all inclusion criteria and were screened, they will be randomized to 20 or 40 mg AR19 daily or placebo.

What is being measured

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

  1. Change From Baseline in Severity of Attention Deficit Hyperactivity (ADHD) Symptoms

    Change from baseline in severity of Attention Deficit Hyperactivity (ADHD) symptoms, as measured by the adult ADHD Investigator Symptom Rating Scale (AISRS), with a minimum score of 0, and maximum score of 54. Higher scores indicate more severe symptoms, or a worse outcome.

    Measured: Week 5 (Visit 7)

Secondary outcomes (4)
  1. Change From Baseline to Visit 7 in AISRS Hyperactive and Inattentive Subscale Scores

    Items are scored as follows: 0 (none), 1 (mild), 2 (moderate), 3 (severe). The maximum total score for the scale is 54 points, with 27 points for each subscale (summed). The total score is the sum of the inattentive and hyperactive-impulsive subscales. Higher values represent more severe hyperactivity and/or inattentiveness.

    Measured: Up to 5 weeks

  2. Change in Clinical Global Impression of Severity (CGI-S) Score From Baseline

    CGI-Severity (CGI-S): The CGI-Severity (CGI-S) asks the clinician one question: "Considering your total clinical experience with this particular population, how mentally ill is the patient at this time?" which is rated on the following seven-point scale: 1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill patients.

    Measured: Up to 5 weeks

  3. Change in Clinical Global Impression of Improvement (CGI-I) Score From Baseline

    "Compared to the patient's condition at admission to the project [prior to medication initiation], this patient's condition is: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment."

    Measured: Up to 5 weeks

  4. Change in Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) Score From Baseline

    The Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) is a 75-item self-rating scale that assesses overall functioning (GEC) and 9 non-overlapping scales among 2 summary index scales (Metacognition Index [MI] and Behavioral Regulation Index [BRI]) that assess aspects of executive function and problems with self-regulation from the perspective of the individual.

    Subjects rate each item on a 3-point scale (1=Never, 2=Sometimes, or 3=Often) based on their experience in past month.

    The sum of 70 items yields the GEC raw score (range: 70-210), which is converted to a T-score (normative population mean=50 and standard deviation=10; T-score ≥ 65 is considered abnormally elevated). The post-baseline GEC T-score is converted to a change from baseline T-score.

    A lower change from baseline GEC T-score (<0) represents a better outcome.

    Measured: Up to 5 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Amphetamine Sulfate in people with Attention Deficit Hyperactivity Disorder, run by Arbor Pharmaceuticals, Inc. at 31 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 11 inclusion and 47 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 3 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 31 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 3 Sep 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?

Change From Baseline in Severity of Attention Deficit Hyperactivity (ADHD) Symptoms (time frame: Week 5 (Visit 7)). 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 NCT03659929, 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 3 Sep 2024.
