Non-drug Study to Evaluate the Suitability of Neurocognitive Tests and Functioning Scales for the Measurement of Cognitive and Functioning Changes in Children With Down Syndrome

October 24, 2017 updated by: Hoffmann-La Roche

A Multicenter, Longitudinal, Non-drug Study to Assess the Suitability of Neurocognitive Tests and Functioning Scales for the Measurement of Cognitive and Functioning Changes in Children With Down Syndrome

The aim of this study is to assess the suitability of selected scales (floor/ceiling effects, variability, test-retest reliability) to measure cognitive function in children with Down syndrome over 6 months, and to evaluate the influence of covariates such as age, gender or language on these neurocognitive scales.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 7 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Male and female children, 6 to 11 years of age inclusive, with diagnosis of Down syndrome.

Description

Inclusion Criteria:

  • Males and females aged 6 to 11 with diagnosis of Down syndrome (Trisomy 21). Children may have standard trisomy 21, Robertsonian translocation, isochromosome 21 (so called 21q21q Robertsonian translocation), Down syndrome with reciprocal translocation or mosaicism.
  • Down syndrome children meeting clinical diagnostic criteria for generalized anxiety disorders, autism spectrum disorder, attention deficit and hyperactivity disorder, can participate in the study provided they are considered clinically stable or on stable medication for at least 8 weeks prior to the baseline visit.
  • Parent or legal guardian/representative and caregiver willing to give written informed consent.
  • Subjects with sufficient vision and hearing to engage in study evaluations as referred by their parents. Mild hearing loss will be allowed.

Exclusion Criteria:

  • Children who may not be able to comply with the protocol or perform the outcome measures due to significant hearing or visual impairment or other issues judged relevant by the investigators
  • Significant sleep disruption or moderate to severe untreated obstructive sleep apnea.
  • Any condition which would make the individual or the caregiver, in the opinion of the investigator, unsuitable for the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Neurocognitive batteries/tests/scales: Suitability for individuals with Down syndrome assessed by number of tests completed/subjects completing, ceiling/floor effect, variance estimate of baseline/change from baseline
Time Frame: approximately 6 months
approximately 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Test/re-test reliability: Changes in test results over 6 months
Time Frame: approximately 6 months
approximately 6 months
Influence of age on several neurocognitive tests and functioning scales in the Down syndrome population
Time Frame: approximately 6 months
approximately 6 months
Correlations between test results on functioning, adaptive behavior and cognition and IQ level
Time Frame: approximately 6 months
approximately 6 months

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
