About this study

The purpose of this pilot study is to compare Adderall ® and Adderall XR ® in terms of their effectiveness and side effects for the treatment of ADHD in adults.

Read the detailed description

This will be a randomized, cross-over study in which adults with ADHD will receive three weeks of treatment with Adderall (IR) (15, 30, or 45 mg TID) and three weeks of treatment of Adderall XR (XR) (15, 30, or 45 mg QD) for evaluation of dosing adherence and treatment efficacy. The order of the two conditions (TID-QD or QD-TID) will be counterbalanced across subjects, with a washout period in between treatment periods. Participants will be required to come to the site for 9 visits over approximately an 8-week period.

The study will consist of the following four phases:

  • Phase 1
  • Screening Visit (Visit 1)
  • Treatment "A" Baseline Visit (Visit 2)
  • Phase 2
  • Treatment Period "A" - participants will take either Adderall or Adderall XR for 3 weeks (Visits 3-5)
  • Phase 3
  • 7-Day Washout Period - participants will be off Treatment "A" medication
  • Treatment "B" Baseline visit (Visit 6)
  • Phase 4 o Treatment Period "B" - participants will take either Adderall or Adderall XR for 3 weeks (Visits 7-9)

Eligible participants will be randomized in a 1:1 ratio to one of two schedules of treatment, Adderall IR followed by Adderall XR, or Adderall XR followed by Adderall IR. Within both schedules, each treatment will consist of a 3-week dose optimization titration evaluation period with a washout week prior to switching to the second respective treatment. The maximum total daily dose will be 45mg, with 15mg TID for IR or 45mg QD for XR. Throughout the medication treatment periods, participants will visit the clinic weekly for evaluations of efficacy, tolerance, and adherence. Medical evaluations will also be conducted at each treatment visit, including assessment of weight, blood pressure, and pulse. Efficacy and adherence data will collected by separate research staff, so that the rater evaluating efficacy will be blinded to the adherence results. The clinician evaluating efficacy will also be blinded to the participants' treatment assignment.

What participants receive

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

  • Adderall ® Immediate ReleaseDrug

    Adderall Immediate release (IR) was provided as treatment for three weeks (at 15, 30 or 45 mg TID). The medication was optimized for titration.

  • Adderall XR ®Drug

    Also called extended release adderall

    Adderall Extended Release (XR) was provided as treatment for three weeks at (15, 30, or 45 mg QD). The medication was optimized for titration.

Study groups in NCT00468143
Study groupRoleWhat they receive
Adderall Extended Release FirstExperimentalThis group was treated with Adderall extended release, either during phase 2 of the trial, or during phase 3 (this subset received Adderall immediate release during phase 2 and then underwent a washout period). This was a counterbalanced crossover study, with a washout period in between treatment periods. Participants were randomized in a 1:1 ratio to one of two schedules Adderall IR followed by Adderall XR, or Adderall XR followed by Adderall IR.

What is being measured

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

  1. Medication Event Monitoring System (MEMS®) Dosage Adherence

    Dosage adherence (MEMSd) is the number of bottle openings divided by number of doses prescribed. Adherence was measured as ≥ 75% of the doses. The number below is the total percentage of subjects who were adherent.

    Measured: The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)

  2. Medication Event Monitoring System (MEMS®) Regimen Adherence

    Regimen adherence (MEMSr) is a percentage of the number of days in which the complete dose regimen was taken as prescribed. Adherence was measured as complete dose regimen taken on ≥ 90% of days. The number below is the total percentage of subjects who were adherent.

    Measured: The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)

  3. Medication Event Monitoring System (MEMS®) Time Adherence

    Time adherence (MEMSt) is the percentage of doses taken as prescribed within a specified time period. Adherence was measured as ≥ 80% of doses taken at the correct time. The number below is the percentage of subjects who were adherent.

    Measured: The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)

Secondary outcomes (2)
  1. Pill Count

    Study staff counted unused medication at each weekly visit to yield a percentage of prescribed pills that were consumed. For each group, the number given will be the total number of consumed pills divided by total number of pill prescribed.

    Measured: At clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)

  2. Self Report

    Self-reported adherence was ascertained via retrospective self-report of daily regimen adherence. Participants were considered adherent for Adderall IR (Methamphetamine salts) if they took the first does in the morning within 30 minutes of waking, and then each subsequent dose in 5-hour intervals (within 30 minutes). For Adderall XR (Methamphetamine salts), participants were considered adherent if they took the single daily dose in the morning within 30 minutes of waking. The number given below represents the total number of self-reported adherent participants divided by the total number of participants per group, times 100 (to obtain percentage).

    Measured: At clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)

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 9 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 2 Jun 2016. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 2 Jun 2016). 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?

Medication Event Monitoring System (MEMS®) Dosage Adherence (time frame: The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)). The study lists 3 primary outcomes in all. 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 NCT00468143, 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?
