About this study

Official title: Long-term Effects of Medication for Attention Deficit Hyperactivity Disorder (ADHD) in Children and Adolescents on Cognition, Everyday Function and Quality of Life

Single-centre open-label prospective study, enrolling 127 children and adolescents aged 6-17 years, who receive medication for ADHD of any subtype (presentation). Long-term results are evaluated with tests of ADHD symptoms (Qb-test), intellectual ability (Wechsler scales; WISC), adaptive functioning (Vineland scale), everyday functioning (Weiss Functional Impairment Scale; WFIRS), and quality of life (Child Health and Illness Profile-Child Edition Scale; CHIP-CE) during 24 months of ADHD treatment.

Read the detailed description

Single-centre open-label prospective study, including 127 subjects over a period of 2 years. Children and adolescents (6-17 years) who have been diagnosed with ADHD will be enrolled and followed during 24 months of ADHD treatment.

Screening assessments include medical, neurodevelopmental and psychiatric history, clinical evaluation and definition of the ADHD diagnosis and its subtypes or presentations (according to Diagnostic and Statistical Manual (DSM) IV and DSM 5), ADHD symptom severity and global functional impairment (by the investigator-rated ADHD Rating Scale-IV (ADHD-RS-IV) and Clinical Global Impression Scale-Severity and Improvement; CGI-S and CGI-I), comorbidities (by the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) clinical interview), intellectual ability (by the WISC test), and general level of functioning (by the Vineland interview). Subjects previously assessed and diagnosed will be re-assessed at the screening visit to ascertain a current evaluation and definition of these parameters.

At baseline, a Qb-test and an assessment of symptom severity and global functional impairment will be made by the investigator-rated ADHD-RS-IV and CGI-S, everyday functioning by parent-rated WIFRS, and quality of life by parent-rated CHIP-CE. An adverse events report will be collected by interview with open-ended questions. Assignment to treatment will be individualized according to clinical picture and patient preference.

At subsequent visits (1, 2, 3, 6, 12, 18 and 24 months) the following assessments will be performed: Investigator-rated ADHD-RS-IV, CGI-S, Clinical Global Impression-Improvement (CGI-I) scales for symptom severity, global functional impairment and improvement. Adverse event report. Compliance assessment through pill count. Assessment of comorbidity status according to DSM-IV and DSM 5 checklist/interview.

A Qb-test will be performed at the 1 and 12 month visits. Everyday functioning and quality of life will be assessed by parent-rated WIFRS and CHIP-CE scales at the 12 and 24 month visits.

Duration of study treatment per subject is 24 months. Medication dosage is 1-3 doses daily as needed to optimize symptom control. Medications (methylphenidate, amphetamine, atomoxetine) will be provided by the pharmacy according to routines in standard clinical treatment.

For cluster analysis of Qb-test results, retrospective data from at least 50 patients previously diagnosed at our clinic will be added to the data from the subjects participating in the prospective study, to increase sample size to ascertain sufficient power for subgroup (cluster) analysis.

Safety evaluations Adverse event (AE) reports will be collected at all visits through open-ended questions. Vital signs (height, weight, blood pressure, pulse) will be assessed at all visits. AE severity should be graded: Mild, Moderate or Severe, and all AEs must be followed until an outcome is known, ensuring the subject's safety. All AEs will be recorded in the subject's medical records and in the Clinical Report Form (CRF), and also reported to the Medical Products Agency according to local regulations.

Study population Approximately 100 subjects from our centre will be enrolled in the prospective study.

Retrospective data for the cluster analysis will be collected from at least 50 patients previously diagnosed at our centre.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ADHD medications in people with Attention Deficit Disorder With Hyperactivity, run by Göteborg University at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 in CGI - (S and I) (time frame: 0, 1, 2, 3, 6, 12, 18 and 24 months). 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 14 Mar 2022.
