Outcome Measures
Primary Outcomes (3)
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.
The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)
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.
The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)
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.
The MEMS information was noted at clinic visit 3, 4, 5, 7, 8, and 9 (over 8 weeks)

Study Arms (2)
Adderall Extended Release First
EXPERIMENTALThis 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.
Adderall Immediate Release First
EXPERIMENTALThis group was treated with Adderall immediate release, either during phase 2 of the trial, or during phase 3 (this subset received Adderall extended 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.
Interventions
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 Extended Release (XR) was provided as treatment for three weeks at (15, 30, or 45 mg QD). The medication was optimized for titration.
Eligibility Criteria
You may qualify if:
- At the time of consent, are between the ages of 18-55, inclusive.
- Meet DSM-IV criteria for ADHD as assessed by the Adult ADHD Clinician Diagnostic Scale (ACDS) v1.2.
- Female participants of childbearing potential must test negative for pregnancy at the time of enrollment based on a urine pregnancy test and agree to use a reliable method of birth control during the study. Females of childbearing potential are defined as women not surgically sterilized and are between menarche and 2 years post-menopause.
- Must have a satisfactory medical assessment with no clinically significant abnormalities as determined by medical history, physical exam, ECG, and clinical laboratory testing.
- Must be able to swallow capsules.
- Must be able to begin the daily dose of study medication in the morning.
- Must be off previous amphetamine or methylphenidate treatment for 1 week prior to baseline (visit 2). Must be off past non-stimulant ADHD medication (i.e., atomoxetine) for 3 weeks prior to baseline (visit 2).
- In the opinion of the investigator, the subject must understand and be able, willing and likely to fully comply with the study procedures and restrictions.
- Must have given signed and dated informed consent in accordance with Good Clinical Practice (GCP) Guidelines.
You may not qualify if:
- Lifetime or present history of bipolar disorder, schizophrenia or schizoaffective disorder.
- Uncontrolled comorbid major depressive disorder, anxiety disorder or dysthymia. Participants with controlled depressive or anxiety disorders may participate if their medications have been stabilized for a minimum of four weeks and, in the opinion of the Principal Investigator, will not interfere with adherence, safety, or efficacy assessments.
- Anyone who meets current DSM-IV-TR criteria for alcohol or any non-alcohol substance abuse or dependence disorder (excluding nicotine).
- Have organic brain disease (such as dementia) or traumatic brain injury residua. Have a history of seizure disorder (other than febrile seizures) or participants who have taken (or are currently taking) anticonvulsants for seizure control.
- Females who are currently pregnant or breast feeding, and women of child-bearing potential who are not currently using an adequate form of birth control.
- Participants who work the night shift or another schedule that would preclude beginning the daily dose of study medication in the morning.
- Participants with a positive urine drug result at Screening.
- Participants with any concurrent chronic or acute illness or unstable medical condition that could, in the opinion of the study physician, confound the results of safety assessments, increase risk to the subject or lead to difficulty complying with the protocol. Subjects who have a history of mental retardation or severe learning disability will be excluded.
- Participants with a history of structural cardiac abnormalities as well as any other condition that may affect cardiac performance.
- Participants with documented history of allergy, intolerance, or non-responsivity to methylphenidate or amphetamines. This includes a history of two or more failed stimulant treatment trials, as deemed by the Principal Investigator.
