Safety and efficacy of Vyvanse 30, 50, and 70 mg/day were compared with placebo in a randomized, double-blind, parallel-group, placebo-controlled, 4-week study with forced-dose titration.1,2
Primary Endpoint: Change from baseline to endpoint* in ADHD-RS-IV total score1,2
Secondary Endpoint: Duration of efficacy as measured by CPRS ADHD index at 10 AM, 2 PM, and 6 PM1,2
*Last postrandomization treatment week for which a valid ADHD-RS-IV total score was obtained.
ADHD-RS-IV=Attention-Deficit/Hyperactivity Disorder Rating Scale, Version IV, a validated, investigator-rated measure that consists of 18 items designed to reflect the symptomatology of ADHD based on DSM-IV-TR® criteria.
CPRS=Conners’ Parent Rating Scale, an instrument that uses parent ratings to help assess ADHD symptoms and behaviors in children. In this study, parents rated their child’s symptomatic behaviors at 10 AM, 2 PM, and 6 PM.

Vyvanse provided a 56% average reduction in ADHD-RS-IV total score (from 43.9 to 19.5) for all doses combined vs a 14% average reduction for placebo (from 42.4 to 36.6)†1-3
†P<.0001 for Vyvanse vs placebo.

Duration of efficacy of Vyvanse was assessed in a randomized, double-blind, placebo-controlled, crossover, analog classroom study.1,2
During a 4-week, open-label, dose-optimization phase, subjects were titrated to an optimal dose of Vyvanse 30 mg, 50 mg, or 70 mg/day in the morning. They were randomized in the double-blind crossover phase to receive Vyvanse (optimized dose) followed by placebo, or placebo followed by Vyvanse, each for 1 week of treatment. During the double-blind phase, efficacy assessments occurred at the end of each week in the analog classroom setting using the SKAMP-D subscale.1,2
Primary Endpoint: Time of onset of Vyvanse compared with placebo in the analog classroom setting, as measured by average SKAMP-D subscale scores2
Key Secondary Endpoint: Duration of efficacy of Vyvanse compared with placebo in the analog classroom setting, as measured by average SKAMP-D subscale scores evaluated at 1.5, 2.5, 5, 7.5, 10, 12, and 13 hours postdose2
DSM-IV-TR®=Diagnostic and Statistical Manual of Mental Disorders, 4th ed, text revision.
SKAMP-D (Swanson, Kotkin, Agler, M-Flynn, and Pelham Deportment) subscale is a validated, standardized classroom assessment tool that measures behavior problems leading to classroom disruptions. It is not a measure of classroom or academic performance. Lower scores indicate less severe symptoms.2
Duration of efficacy was not systematically evaluated in patients aged 13-17.
Primary Endpoint: At 1.5 hours postdose, SKAMP-D score of .70 for Vyvanse vs 1.14 for placebo (P<.005)1,2
Children aged 6-12 with ADHD treated with Vyvanse, experienced a statistically significant improvement in their SKAMP-D score throughout the day at every timepoint measured, up to 13 hours postdose vs placebo.1,2

Maintenance of symptom control with Vyvanse was assessed in a multicenter, double-blind, placebo-controlled, randomized withdrawal study. Patients were treated with open-label Vyvanse 30, 50, or 70 mg/day for at least 26 weeks prior to being assessed for entry into the 6-week, double-blind, randomized withdrawal phase. Eligible patients had to demonstrate treatment response as defined by ADHD-RS-IV total score ≤22 and CGI-S ≤2.1,2
Primary Endpoint: The proportion of patients with treatment failure (relapse) during the 6-week, randomized withdrawal phase. Treatment failure (relapse) was defined as ≥50% increase (worsening) in ADHD-RS-IV total score and a ≥2-point increase in CGI-S score compared to scores at entry of the randomized withdrawal phase. Patients who met treatment failure criteria were immediately withdrawn from the study.1,2

ADHD-RS-IV=Attention-Deficit/Hyperactivity Disorder Rating Scale, Version IV, a validated, investigator-rated measure that consists of 18 items designed to reflect the symptomatology of ADHD based on DSM-IV-TR® criteria.
CGI-S=Clinical Global Impression Severity, a scale which assesses the clinician's impression of the patient's current illness state and ranges from 1 (not at all ill) to 7 (extremely ill).
A significantly lower proportion of treatment failures occurred among those children taking Vyvanse (15.8%) compared to placebo (67.5%) at endpoint* of the randomized withdrawal phase1,2
*The endpoint measurement was defined as the last post-randomization treatment week at which a valid ADHD-RS-IV total score and CGI-S score were observed.
Hypothetical patient portrayal.
Individual results may vary.
Only Vyvanse (lisdexamfetamine dimesylate) has 5 administration options, so you can tailor treatment to meet the needs of each pediatric ADHD patient (ages 6-17).
