About this study

Official title: A Randomized, Double-Blind Study of the Time Course of Response to Biphentin® Methylphenidate Hydrochloride ER Capsules Compared to Placebo in Children 6 to 12 Years With Attention Deficit Hyperactivity Disorder in Analog Classroom Setting

The time course of response following one dose of a new methylphenidate hydrochloride extended release capsule is studied in children 6-12 years in a simulated laboratory classroom setting. Biphentin methylphenidate hydrochloride extended release capsule has been formulated for daily dosing to provide treatment of a child with Attention deficit hyperactivity disorder (ADHD) for the substantial day.

Read the detailed description

Biphentin methylphenidate hydrochloride (HCl) extended release (ER) capsules is provided in multiple strengths of 10, 15, 20, 30, 40, 50, and 60 mg to be administered once daily. Once daily dosing is intended to provide treatment for the substantial day.

For current analog classroom study each eligible subject will be optimized at 15, 20, 30, or 40 mg in a timeframe of five weekly periods. In the sixth week each subject will be randomized double-blind to receive either active comparator at the optimized dose or placebo comparator treatment. The first classroom session will be held at the end of the week, when efficacy measurements including Swanson, Kotkin, Agler, M-Flynn, Pelham Rating Scale (SKAMP) and Permanent Product Measure of Performance (PERMP) tests will be administered. At the beginning of the following week, the subjects will be crossed-over to the corresponding active comparator or placebo comparator treatment. The second classroom session will be held at the end of the second double-blind week, when the same efficacy measurements will be administered.

Various safety and tolerability, and quality of life assessments will be conducted.

Double Blind Phase (2-weeks): Placebo: Capsule without active drug for 1 week Methylphenidate HCl ER Capsule: An optimized dose of Methylphenidate hydrochloride extended release capsules (15, 20, 30, or 40 mg) for 1 week Dosed once daily in the morning

What is being measured

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

  1. Comparison Following Treatment Between Drug and Placebo Using Evaluation by SKAMP Combined, Attention, and Deportment Scales

    Comparison of Swanson, Kotkin, Alger, M-Flynn and Pelham (SKAMP) Combined, Attention, and Deportment Scales following drug dose versus placebo.

    The SKAMP scale is a validated rating scale that assesses behavioral symptoms of ADHD in a classroom setting using a 7-point impairment scale (0 = none through 6 = maximal impairment). The SKAMP total score comprises 13 items, with individual total scores ranging from 0 to 78 (lower scores mean better outcome). The SKAMP-D subscale evaluates deportment, including interacting with other children, interacting with adults, remaining quiet according to classroom rules, and staying seated according to classroom rules. The SKAMP-A subscale is a measure of attention and evaluates getting started on assignments, sticking with tasks, attending to an activity, and making activity transitions. The SKAMP quality of work subscale includes 3 items: completing assigned work, performing work accurately, and being careful and neat while writing or drawing.

    Measured: Average over all post-dose time points (1.0, 2.0, 3.0, 4.5, 6.0, 7.5, 9.0, 10.5, and 12 hours)

Secondary outcomes (1)
  1. Comparison Following Treatment With Drug or Placebo Using PERMP (Permanent Product of Arithmetic) Evaluations

    Comparison of PERMP measurement scores following drug dose versus placebo (math-correct).

    The Permanent Product Measure of Performance (PERMP), is a 5-page test consisting of 80 math problems per page (total of 400 problems) and evaluates effortful performance in the classroom as a measure of efficacy. Participants are instructed to work at their seats and to complete as many problems as possible in 10 minutes. The appropriate level of difficulty for each student was determined previously based on results of a math pretest administered at screening. Performance was evaluated using PERMP-A) and PERMP-C scores.

    Measures obtained from these tests include the number of problems attempted (Math-Attempted; PERMP-A) and the number of problems answered correctly (Math-Correct; PERMP-C). Higher scores are better. The responses are reviewed by comparing them to an answer template, and they are triple-checked for accuracy

    Measured: 12 hours post-dose

A Phase 3 study testing Methylphenidate Hydrochloride Extended Release Capsule in people with Attention Deficit Hyperactivity Disorder and ADHD, run by Rhodes Pharmaceuticals, L.P. at 1 site 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 6 inclusion and 12 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 13 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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 13 Dec 2022). 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?

Comparison Following Treatment Between Drug and Placebo Using Evaluation by SKAMP Combined, Attention, and Deportment Scales (time frame: Average over all post-dose time points (1.0, 2.0, 3.0, 4.5, 6.0, 7.5, 9.0, 10.5, and 12 hours)). 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 NCT01269463, 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 13 Dec 2022.
