What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Therapeutic Drug MonitoringOther

    Physician receives dosing advice based on risperidone plasma level.

  • Risperidone plasma levelOther

    Plasma levels of risperidone and 9-OH risperidone are measured in a Dried Blood Spot.

What is being measured

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

  1. BMI z-score

    Difference in body mass index z-scores 6 months after start of treatment.

    Measured: 6 months

Secondary outcomes (11)
  1. Effectivity (ABC)

    Difference on the Irritability scale of the Aberrant Behavior Checklist (scores ranging from 0 to 45, a higher score means more symptoms) 6 months after start of treatment.

    Measured: 6 months

  2. Effectivity (CGI)

    Difference on the Clinical Global Impression scale (scores ranging from 1 to 7, a higher score means higher severity) 6 months after start of treatment.

    Measured: 6 months

  3. Quality of Life (PedsQL)

    Difference on Pediatric Quality of Life Inventory (scores ranging from 0 to 100, a higher score indicates a better quality of life) 6 months after start of treatment.

    Measured: 6 months

  4. Metabolic side effects (glucose)

    Difference in level of glucose 6 months after start of treatment.

    Measured: 6 months

  5. Metabolic side effects (cholesterol)

    Difference in levels of cholesterol and lipoproteins (LDL, HDL) 6 months after start of treatment.

    Measured: 6 months

  6. Metabolic side effects (triglycerides)

    Difference in level of triglycerides 6 months after start of treatment.

    Measured: 6 months

  7. Endocrine side effects (prolactin)

    Difference in level of prolactin 6 months after start of treatment.

    Measured: 6 months

  8. Extrapyramidal symptoms (EPS)

    Difference in extrapyramidal symptoms measured by Abnormal Involuntary Movement Scale 6 months after start of treatment.

    Measured: 6 months

  9. Endocrine side effects (ghrelin)

    Difference in level of ghrelin 6 months after start of treatment.

    Measured: 6 months

  10. Endocrine side effects (leptin)

    Difference in level of leptin 6 months after start of treatment.

    Measured: 6 months

  11. Side effects (blood pressure)

    Difference in diastolic and systolic blood pressure 6 months after start of treatment.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Therapeutic Drug Monitoring and Risperidone plasma level in people with Autism Spectrum Disorder, run by Erasmus Medical Center at 1 site in Netherlands.

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 3 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: status not confirmed, as of the sponsor's last update on 8 Dec 2023. 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 Netherlands. 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?

Results are not available in the source record.

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

Contact Birgit Koch (b.koch@erasmusmc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BMI z-score (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05146245, which also lists 1 linked publication.

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 8 Dec 2023.
