Study summary

Hypothesis: Children diagnosed with a lysosomal disease will exhibit developmental, adaptive, and behavioral strengths and difficulties depending upon 1) biomedical risk factors (i.e. the specific genetic disorder responsible for the illness); 2) available modifying interventions, whether medical or behavioral; and 3) social risks in the children's families, neighborhoods and communities. A valid and reliable telephone-based surveillance system can successfully collect the data required to elucidate these developmental, adaptive and behavioral strengths and difficulties.

Read the detailed description

Children who have lysosomal disease experience declines in health status and central nervous system integrity which result in motor, communication, self-care, learning and behavioral challenges. Medical interventions such as enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation can improve the health and functioning of children with lysosomal disease. To date, however, there is no established system for evaluating the health status, developmental status, behavioral outcomes or functional outcomes of these preschool-aged children across time and differing settings. The primary objective of this study is to develop a valid and reliable telephone-based data-gathering system for obtaining health status data, developmental status data, behavioral outcomes data, and functional outcomes data which reflect skills of daily living including feeding, moving, communicating and responding to others.

The secondary objective of this study is to assess the validity of several early-childhood standardized assessment tools as compared to the standard neuropsychological assessment battery specified by the Lysosomal Disease Network's 'Neurobehavioral Core.'

The third objective of this study is to describe the impact of lysosomal disease upon the families of lysosomal disease-affected children.

What researchers measure

Primary outcomes

  1. Change in Health Status of the Lysosomal Disease-Affected Child Measured at 6-month Intervals for 5.5 Years

    Using the technique of telephone-based interviews with the child's care-giver(s), the investigators will obtain and record verbal responses to a variety of standardized assessment tools which seek to ascertain the lysosomal disease-affected child's health status.

    Time frame: Upon Enrollment, and thereafter at 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 and 66 months post-enrollment

Secondary outcomes

  1. Change in the Behavioral Outcomes of the Immediate Family of the Lysosomal Disease-Affected Child Measured at 6-month Intervals for 5.5 Years

    Using the technique of telephone-based interviews with the child's care-giver(s), the investigators will obtain and record verbal responses to a variety of standardized assessment tools which seek to ascertain the behavioral outcomes of the immediate family of the lysosomal disease-affected child.

    Time frame: Upon Enrollment, and thereafter at 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 and 66 months post-enrollment

  2. Change in Developmental Status of the Lysosomal Disease-Affected Child Measured at 6-month Intervals for 5.5 Years

    Using the technique of telephone-based interviews with the child's care-giver(s), the investigators will obtain and record verbal responses to a variety of standardized assessment tools which seek to ascertain the lysosomal disease-affected child's developmental status.

    Time frame: Upon Enrollment, and thereafter at 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 and 66 months post-enrollment

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 4, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
