About this study

This is a prospective (study following participants forward in time), single-arm, open-label (all people know the identity of the intervention), 8-week, multi-centric (conducted in more than 1 center) study. OROS-MPH will be administered orally for 2 months at doses of 18, 36, or 54 milligram (mg) to replace IR-MPH. Clinicians will adjust the dose of each participant according to participant's clinical responses and/or side effects. During the study period, participants will be assessed on Week 2, 4, and 8. Efficacy will be evaluated primarily based on change from baseline in Chinese version of the 26-item Swanson, Nolan and Pelham-Fourth Edition (SNAP-IV) rating scale assessed by parents and Chinese Health Questionnaire (CHQ). Safety will be monitored throughout the study.

Primary outcomes

  1. Mean Change From Baseline in Swanson, Nolan and Pelham-Fourth Edition (SNAP-IV) Rating Scale (Parents) Score at Week 2

    Time frame: Baseline and Week 2

    Parents were asked to assess their children on a 26-item Chinese SNAP-IV questionnaire consisting of inattention (items 1-9; subscore range 0-27), hyperactivity (items 10-18; subscore range 0-27) and oppositional (19-26, subscore range 0-24) subscales used to assess the qualitative judgments in Attention Deficit Hyperactivity Disorder (ADHD). Each item was based on a 4-point likert scale ranging from 0 (not at all) to 3 (very much). The overall score ranged from 0 to 78. The total score for Inattention and hyperactivity ranged from 0 to 27 and for oppositional ranged from 0 to 21. Mean Change was calculated as mean SNAP-IV score at Week 2 minus mean SNAP-IV score at Baseline.

  2. Mean Change From Baseline in Swanson, Nolan and Pelham-Fourth Edition (SNAP-IV) Rating Scale (Parents) Score at Week 4

    Time frame: Baseline and Week 4

    Parents were asked to assess their children on a 26-item Chinese SNAP-IV questionnaire consisting of inattention (items 1-9; subscore range 0-27), hyperactivity (items 10-18; subscore range 0-27) and oppositional (19-26, subscore range 0-24) subscales used to assess the qualitative judgments in Attention Deficit Hyperactivity Disorder (ADHD). Each item was based on a 4-point likert scale ranging from 0 (not at all) to 3 (very much). The overall score ranged from 0 to 78. The total score for Inattention and hyperactivity ranged from 0 to 27 and for oppositional ranged from 0 to 21. Mean Change was calculated as mean SNAP-IV score at Week 4 minus mean SNAP-IV score at Baseline.

  3. Mean Change From Baseline in Swanson, Nolan and Pelham-Fourth Edition (SNAP-IV) Rating Scale (Parents) Score at Week 8

    Time frame: Baseline and Week 8

    Parents were asked to assess their children on a 26-item Chinese SNAP-IV questionnaire consisting of inattention (items 1-9; subscore range 0-27), hyperactivity (items 10-18; subscore range 0-27) and oppositional (19-26, subscore range 0-24) subscales used to assess the qualitative judgments in Attention Deficit Hyperactivity Disorder (ADHD). Each item was based on a 4-point likert scale ranging from 0 (not at all) to 3 (very much). The overall score ranged from 0 to 78. The total score for Inattention and hyperactivity ranged from 0 to 27 and for oppositional ranged from 0 to 21. Mean Change was calculated as mean SNAP-IV score at Week 8 minus mean SNAP-IV score at Baseline.

  4. Mean Change From Baseline in Chinese Health Questionnaire (CHQ) at Week 4

    Time frame: Baseline and Week 4

    The CHQ is a self administered screening instrument used to assess psychiatric morbidity in the Chinese community. It was derived from the General Health Questionnaire, and has been validated with satisfactory construct validity and applied in the survey of psychiatric morbidity in the community and in hospital settings. Four factors are included in the structure: somatic symptoms; anxiety and worrying; sleep problems; and depression and poor family relationships. It contains 12 items, with a maximum score of 12. CHQ scores indicated the severity of participants' psychological problems (0-2=normal; 3-4=minor; 5-6=moderate; and 7-12=severe psychological problems). Mean Change was calculated as mean CHQ score at Week 4 minus mean CHQ score at Baseline.

  5. Mean Change From Baseline in Chinese Health Questionnaire (CHQ) at Week 8

    Time frame: Baseline and Week 8

    The CHQ is a self administered screening instrument used to assess psychiatric morbidity in the Chinese community. It was derived from the General Health Questionnaire, and has been validated with satisfactory construct validity and applied in the survey of psychiatric morbidity in the community and in hospital settings. Four factors are included in the structure: somatic symptoms; anxiety and worrying; sleep problems; and depression and poor family relationships. It contains 12 items, with a maximum score of 12. CHQ scores indicated the severity of participants' psychological problems (0-2=normal; 3-4=minor; 5-6=moderate; and 7-12=severe psychological problems). Mean Change was calculated as mean CHQ score at Week 8 minus mean CHQ score at Baseline.

Secondary outcomes

Each item was based on a 4-point likert scale ranging from 0 (not at all) to 3 (very much). The overall score ranged from 0 to 78. The total score for Inattention and hyperactivity ranged from 0 to 27 and for oppositional ranged from 0 to 21.

  3. Social Adjustment Scale Score for Children and Adolescents (SAICA)

    Time frame: Baseline, Week 4 and Week 8

    SAICA is a 77-item semi-structured interview scale designed for administration to school-aged children with age 6-18 years, or to their parents about their children. SAICA provides an evaluation of children's current functioning in the domains of school, spare time, peer relations, and home behaviors. Each item ranged on a 4-point likert scale ranging from 1 to 4 with a higher mean score indicating either poorer social function or a more severe social problem.

  4. Clinical Global Impression-Severity (CGI-S) Score

    Time frame: Baseline, Week 2, 4 and 8

    CGI-ADHD-S is a single item assessment of the global severity of ADHD symptoms in relation to the clinician's total experience after reviewing all the returned questionnaires and clinical assessment of participants' behavioral symptoms. Severity is rated on a 7-point scale ranging from 1 to 7 with 1=normal (not at all ill) and 7=most extremely ill.

  5. Number of Participants With Clinical Global Impression-Improvement (CGI-I) Score

    Time frame: Baseline, Week 2, 4 and 8

    CGI-I is a single item assessment of the global improvement of ADHD symptoms in relation to the clinician's total experience after reviewing all the returned questionnaires and clinical assessment of participants' behavioral symptoms. Improvement is rated on a 7-point scale (1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, and 7=very much worse).

  6. Global Assessment of Satisfaction by Parents/Caregivers
