Current Primary Outcome Measures ICMJE |
Gray Oral Reading Rest, Fourth Edition (GORT-4) [ Time Frame: baseline and final day (lab school Assessments) ] The GORT-4 evaluates oral reading rate, accuracy and comprehension. Both Forms A and B were used.Half of the subjects randomly were tested on From A at baseline and the other half were tested with Form B.
The GORT-4 is a standardized measure/test. Scores provided are standard scores, which range from 1 to 20, with a Mean of 10 and Standard Deviation of 3. A higher score means better reading performance. There was no total score used or calculated in this study.

Brief Summary | This is a single-blind, Investigator Initiated study to evaluate the safety and efficacy of Vyvanse™ and provide pilot data in two areas: (1) on the use of Near-Infrared Spectroscopy to detect medication effects in children with ADHD; and (2) on the influence of Vyvanse ™ on reading fluency and comprehension, over a period of approximately 6-8 weeks. Subjects will be between the ages of 6 and 12 at the beginning of the study. | |||
Detailed Description | This is a single-blind study to evaluate the safety and efficacy of Vyvanse™ and provide pilot data in two areas: (1) on the use of Near-Infrared Spectroscopy to detect medication effects in children with ADHD; and (2) on the influence of Vyvanse ™ on reading fluency and comprehension over a period of approximately 6 weeks. Subjects will be between the ages of 6 and 12 at the beginning of the study. The study will consist of periods detailed below: Screening and Washout. Subjects will be screened up to four weeks prior to baseline. The washout period will be 3 days for most ADHD stimulant medication (the half life is around 3-5 hours and the washout is at least 5 half-lives in duration). Other medication will be discussed during the visit. The Screening Visit will occur at the UCI Child Development Center and will allow for the determination of appropriateness of each subject's inclusion into the study. The Principal Investigator or his/her designee must obtain written signed and dated consent for the subject to participate in the study from the subject's parent(s)/legally authorized representative and assent must be given by the subject, prior to any study related procedures being performed. This visit is expected to last 3-4 hours and may take place across more than one day. The following procedures will be conducted during the Screening Visit:
In addition, the subject will be asked to give a small blood sample, for safety screening purposes, for laboratory procedures (approximately 2 teaspoons).The following lab procedures will be performed:
Subjects will be provided with a one-week supply of VyvanseTM 30mg/day. Subjects will begin treatment the morning of the baseline visit and continue on the same dose for the next week. The first dose of medication will be administered on site and subsequent dosing will be given to the subject's parent(s)/legally authorized representative who will be required to administer study drug to the subject upon awakening. During the visit subjects will perform the Attention Task while the NIRS is recording and they will also be given the Gray's Oral Reading Test before the medication is administered. After the medication is administered the subject will stay on site until the second NIRS measurement can be taken a second time. They will be provided food and activities during the waiting period. The following procedures will be conducted during the Baseline Visit:
Dose Optimization. During the dose optimization period, subjects will visit the office once per week so that the study doctor can determine if the subject is tolerating the study medication and if she/he is seeing any benefit. These visits will last approximately 45 minutes. The Investigator will review AEs, ADHD-RS-IV, and CGI-I scores, and use clinical judgment to ensure that subjects are titrated to an acceptable dose of VyvanseTM for evaluation. The following procedures will be conducted at each dose optimization visit:
This visit will be similar to the baseline visit. Subjects will arrive early in the morning and medication will be administered on-site. They will remain on site for the next 4 hours so that the dose will be at peak effect before administering the GORT or NIRS. The following procedures will happen during this visit:

Condition ICMJE | Attention Deficit/Hyperactivity Disorder | |||
Intervention ICMJE | Drug: Vyvanse
Subjects will participate in an open-label dose optimization period and successful titration to an optimal dose of Vyvanse™, subjects will take their optimized dose of Vyvanse™ (30, 50 or 70 mg/day) during the week leading up to their final visit. During the study subjects will take their prescribed dose once a day in the morning with breakfast.
