About this study

This is a 12-week clinical trial evaluating the efficacy and safety of memantine hydrochloride (Namenda) in the treatment of executive function deficits (EFDs) in adults with Attention Deficit Hyperactivity Disorder (ADHD) receiving open-label treatment with OROS-Methylphenidate (OROS-MPH, Concerta). The study aims to examine the effects of treatment with memantine on ADHD symptoms. Following screening procedures, memantine is prescribed in randomized, double-blind fashion (equal chance of medication or placebo) for 12 weeks, along with open-label OROS-MPH (everyone receives medication).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PlaceboDrug

    Memantine-matched placebo will be prescribed following approved FDA dosing guidelines for Alzheimer's dementia, beginning at 5mg in AM and increasing in BID doses by 5mg weekly to a maximum dose of 10mg BID.

  • Memantine HydrochlorideDrug

    Also called Namenda

    Memantine will be prescribed following approved FDA dosing guidelines for Alzheimer's dementia, beginning at 5mg in AM and increasing in BID doses by 5mg weekly to a maximum dose of 10mg BID.

  • OROS-MethylphenidateDrug

    Also called OROS-MPH, Concerta

    OROS-Methylphenidate will be openly prescribed, starting with an initial dose of 36mg/day and titrated to optimal response to a maximum daily dose of 1.3mg/kg or 108mg/day, whichever is lower, according to clinician judgment. During titration, dose will be increased on a weekly basis in 36mg/day increments. The dose may be reduced by 18 or 36mg/day increments if adverse effects occur or if the subject discontinues treatment.

What is being measured

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

  1. Percent Change in Global Executive Composite T-Score on the Behavior Rating Inventory of Executive Function-Adult (BRIEF-A)

    This is a 75-item checklist with a large normative sample, internal consistency, test-retest reliability, inter-rater reliability, and external and concurrent validity, divided into nine empirically and theoretically derived and T-scored subscales: Inhibit, Shift, Emotional Control, Self-Monitor, Initiate, Working Memory, Plan/Organize, Task Monitor, and Organization of Materials. Example item: "I make careless errors when completing tasks." Items are rated 1 "Never," 2 "Sometimes," or 3 "Often." The Global Executive Composite (GEC) Score is calculated by totaling all items on the scale. GEC T-scores range from 34-108, with higher scores indicating more difficulties with executive function.

    Measured: baseline, 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Memantine Hydrochloride and OROS-Methylphenidate in people with Attention Deficit Hyperactivity Disorder (ADHD) and Executive Function Deficits (EFD), run by Massachusetts General Hospital 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 4 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 8 Apr 2014. 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. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Feb 2014). 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?

Percent Change in Global Executive Composite T-Score on the Behavior Rating Inventory of Executive Function-Adult (BRIEF-A) (time frame: baseline, 12 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 8 Apr 2014.
