Title: Medication Response in Children With Predominately Inattentive Type ADHD
Brief Summary: This study evaluates how children with Attention Deficit Disorder without Hyperactivity (ADD) respond to medication, and if their response is different from children who have problems with both hyperactivity and inattention. In order to do this, children ages 7-11 whose primary difficulty is with attention problems and who have never been on behavioral or psychiatric medications are being recruited. Once enrolled, children will try one week each of 3 different doses of methylphenidate, the most commonly prescribed Attention Deficit, Hyperactivity Disorder (ADHD) medication, as well as placebo. Children will be randomly assigned to one of six possible medication dose and placebo titration schedules, but the study doctor, family, and teacher will not know which dose (if any) children are receiving for a given week. Each week, behavioral and side effect ratings will be completed by both the child's parent and teacher, and the family will meet with the study doctor for a physical examination and to discuss how each week went. Some children will also have neuropsychological testing to determine how methylphenidate influences their working memory, sustained attention, and ability to inhibit (stop) inappropriate responses.

All data will be analyzed to decide which medication dose the child responded to best and further recommendations for treatment will be given. Ultimately, this study aims to improve understanding of how children with ADHD-Primarily Inattentive Type respond to stimulant medications by

* determining whether these children experience a diminished response to methylphenidate compared to children with both hyperactivity and inattention
* determining whether certain genetic and environmental factors play a role in this response.

Findings from this study will be used to help streamline the identification of the most effective doses of medication for children with ADHD-Primarily Inattentive Type.


Options:
A: Inclusion Criteria:

* clinical symptoms related on diagnosis of ADHD
* age from 6-17 years

Exclusion Criteria:

* retardation
* somatic disorder
B: Inclusion Criteria:

* Consent: The family must provide signature of informed consent by a parent or legal guardian. Children must also assent to study participation.
* Age at Screening:7.0 years to 11.9 years, inclusive.
* Sex: Includes male and female children.
* ADHD Diagnostic Status: Meets DSM-IV criteria for ADHD, Predominantly Inattentive or Combined subtype with Clinical Global Impression-Severity rating corresponding to at least "moderately ill."
* Cognitive Functioning-Intelligence Quotient (IQ) of greater than 80 as estimated by Vocabulary and Block Design subtests of the Wechsler Intelligence Scale for Children--4th Edition, or an Intelligence Quotient (IQ) of 80 or greater when administered the Full Scale Version of the Wechsler Intelligence Scale for Children-4th Edition.
* Absence of Learning Disability:On the abbreviated Wechsler Individual Achievement Test-2nd edition Reading and Math subtests, participants must score above 80. However, children may also be included if they receive a score of 75 or greater on the Word Reading and/or Math subtests, as long as this score is not a significant discrepancy from their full-scale IQ score (e.g., a difference of greater than one standard deviation or 15 points).
* School: Enrolled in a school setting rather than a home-school program.

Exclusion Criteria:

* Understanding Level: Participant and/or parent cannot understand or follow study instructions.
* Psychiatric Medications: Current or prior history of taking any medication for psychological or psychiatric problems.
* Behavioral Interventions: Current active participation in ADHD-related behavioral interventions or counseling.
* Exclusionary Psychiatric Conditions: Children with mania/hypomania and/or schizophrenia will be excluded. The following comorbid diagnoses will not be excluded unless they are determined to be the primary cause of ADHD symptomatology (see below for description of this decision process): Post Traumatic Stress Disorder, Phobias and Anxiety Disorders, Obsessive Compulsive Disorder, Major Depression / Dysthymia, Eating Disorders, Elimination Disorders, Trichotillomania, Tic Disorder, Oppositional Defiant Disorder, Conduct Disorder.
* Organic Brain Injury: History of head trauma, neurological disorder, or other organic disorder affecting brain function.
* Cardiovascular Risk Factors: Children with a personal history or family history of cardiovascular risk factors will be excluded, or given the option of participating in the study after obtaining an EKG and a signed letter from a pediatric cardiologist verifying the safety of their participation in a trial of methylphenidate. In this case, families will be responsible for the costs of EKG and cardiologist evaluation. If for any reason a family is unable to assume the cost of the EKG and cardiologist evaluations but still wishes for their child to participate, study staff will determine on a case-by-case basis whether the study budget allows the study to offer financial assistance to the families for these evaluations.
C: Inclusion Criteria:

* Patients with a physician-confirmed diagnosis of ADHD per Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria and the health care practitioner (HCP) has made the decision to prescribe an extended-release methylphenidate (ER MPH) product to the patient for potential improvement of symptoms throughout and later in the day, independent of this study.
* Patient must be 12 years of age or older.
* Patient must be eligible to receive Adhansia XR or osmotic- release oral delivery system methylphenidate (\[OROS MPH\] or Concerta) according to the US product labels; a patient must be eligible and willing to receive either drug, as randomization will assign them to a specific treatment group. Patient may be treatment-experienced or naïve to pharmacological therapy for ADHD, so long as all inclusion and no exclusion criteria are met.
* Patient must be willing to take only the assigned study medication per HCP instructions based on FDA label guidance for treatment of their ADHD for the first 2 months of the study (i.e. full titration period). Patients should not be on any other medication, or starting any new non-medication treatment, proven to have effect on ADHD in the first two months of the study.

Exclusion Criteria:

* Concurrent participation in an investigational study in which patient assessment and/or treatment may be dictated by a protocol.
* Patients with a true allergy to methylphenidate (MPH), amphetamine (AMP), or sympathomimetic amines, history of serious adverse reactions to MPH or AMP or be known to be non-responsive to MPH or AMP treatment.
* Patient is currently stable on their ADHD treatment regimen.
* Female patients of child bearing potential who are pregnant, planning on becoming pregnant or breastfeeding.
* Patient with any known conditions that are contraindicated for either Adhansia XR or OROS MPH (or Concerta) use, as documented in the US Full Prescribing Information, including patients with any known serious structural cardiac abnormalities, cardiomyopathy, serious heart arrhythmias, or coronary artery disease.
* Patients with a known sensitivity to the food dye tartrazine (Federal Food, Drug, and Cosmetic Yellow No. 5).
* Suicidal Ideation

  * The Columbia-Suicide Severity Rating Scale (C-SSRS) will be administered at screening and at Month-2, Month-4, and Month-6, but also depends on the judgment of the HCP.
* Inability or unwillingness of the patient (or parent/guardian if patient is a minor) to complete the study-required electronic questionnaires and provide required information through electronic means.
D: Inclusion Criteria:

To be eligible for inclusion, each subject must fulfill each of the following criteria at the Entry visit:

* The subject participated in the antecedent SPD485-409 study, and a) completed all required study visits (Baseline through Visit 9) OR b) completed the 5 week Dose Optimization period without achieving an acceptable condition as defined by the antecedent SPD485-409 study.
* Subject has blood pressure measurements within the 95th percentile for age, gender, and height at Entry.
* Subject's ECG results are within the normal range or not clinically significant at Entry as judged by the Investigator in conjunction with the central reader.

* Subject and parent of legally authorized representative (LAR) are able, willing and likely to fully comply with study procedures and restrictions.
* Written, signed and dated informed consent to participate in the study must be given by the subject's parent or LAR, in accordance with the International Conference on Harmonisation (ICH), Good Clinical Practices (GCP) Guideline E6 and applicable regulations, before completing any study-related procedures.
* There must be documentation of the subject's assent to participate in the study indicating that the subject is aware of the investigational nature of the study and the required procedures and restrictions. Failure to object is not to be considered assent.

Exclusion Criteria

Subjects will be excluded from the study if any of the following criteria are met at Entry:

* Subject was discontinued from SPD485-409 due to a protocol violation, non-compliance, AE, or a serious adverse event (SAE).
* Subject has a concurrent chronic or acute illness (such as severe allergic rhinitis or an infectious process requiring antibiotics), disability, or other condition that might confound the results of safety assessments administered in the study or that might increase risk to the subject. Similarly, the subject will be excluded if he or she has any additional condition(s) that in the Investigator's opinion would prohibit the subject from completing the study or would not be in the best interest of the subject. This would include any significant illness or unstable medical condition that could lead to difficulty complying with the protocol. Mild, stable asthma is not exclusionary.
