About this study

Official title: Prospective Follow-Up Observational Study to Examine the Progression of ADHD Drug Treatment and to Analyze Associated Factors

The purpose of this observational study is to explore the efficacy of methylphenidate hydrochloride in children and adolescents diagnosed with attention-deficit hyperactivity disorder (ADHD) by Kiddie-scheduled for affective disorders (SADS)-present and life time version (K-SADS-PL).

Read the detailed description

This is a 1-year open-label (all people involved know the identity of the assigned drug), multicenter, single arm, prospective, observational study to explore under natural setting the efficacy of drug treatment in children and adolescents diagnosed with ADHD by K-SADS-PL (K-SADS-PL is a tool used for ADHD diagnosis. Patient may be diagnosed with ADHD by using K-SADS-PL to check if he or she meets the criteria according to Diagnostic and Statistical Manual of Mental Disorders \& edition (DSM-IV). After obtaining informed consent, investigator will prescribe stimulant or non-stimulant ADHD treatment medications (ie, Immediate release [IR]/extended release [ER]/osmotic release oral system (OROS) methylphenidate, atomoxetine). Efficacy and safety assessments will be performed at 4, 12, 24, 36, and 52 weeks after the first day of giving study drug. Progression of symptom improvement and adherence will be investigated and associated variables (ie, demographic, clinical, familial and treatment factors) will be analyzed.

Study groups in NCT01624649
Study groupRoleWhat they receive
Patients with ADHDPatients will receive methylphenidate hydrochloride or atomoxetine. The methylphenidate hydrochloride is available in three forms. 1) Immediate release 2) Extended release 3) Osmotic release oral system
Receives: Drug: Methylphenidate hydrochloride; Drug: Atomoxetine

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline in the ADHD Rating Scale (ARS)

    The ADHD Rating Scale (ARS) - Parent Version: ARS contains 18 items, in which parent version of the questionnaire is based on home behaviors.

    Measured: Baseline and Week 52

Secondary outcomes (6)
  1. Clinical Global Impression-Severity (CGI-S)

    CGI-S is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Ratings are 1 = normal/not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = extremely ill.

    Measured: Baseline to Week 52

  2. Adherence Rate

    Pill count at each visit; at least 50% adherence rate will be considered clinically relevant.

    Measured: Week 4 to Week 52

  3. Comprehensive Attention Test (CAT)

    CAT is a computerized test which includes attention task, sustained attention to response, flanker task, divided attention task, and spatial working memory task.

    Measured: Baseline, Week 24 and Week 52

  4. Academic Performance Rating Scale (APRS)

    APRS is a 19-item scale, where parents rate the child's academic abilities and behaviors on a 5-point scale. Higher scores indicate greater academic performance.

    Measured: Baseline, Week 24 and Week 52

  5. Symptoms Checklist (SCL-90) for Parent Depression

    Measured: Baseline, Week 24 and Week 52

  6. Clinical Global Impression- Improvement (CGI-I)

    CGI-I is a 7 point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. It is rated as 1, every much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse.

    Measured: Baseline and Week 52

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in the ADHD Rating Scale (ARS) (time frame: Baseline and Week 52). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jun 2015.
