A Study of the Impact of Hemophilia and Its Treatment on Brain Development, Thinking and Behaviour in Children With Hemophilia (eTHINK)

November 21, 2019 updated by: Novo Nordisk A/S

Evolving Treatment of Hemophilia's Impact on Neurodevelopment, Intelligence and Other Cognitive Functions (eTHINK)

The Hemophilia Growth and Development Study (HGDS) nearly 25 years ago showed haemophilia and HIV impacted brain development, thinking, and behaviour in children and adolescents. The eTHINK study is designed to understand whether advances in hemophilia treatment have removed any impact of hemophilia. If there still is an impact of hemophilia, the eTHINK study will help to identify which children or adolescents are still at risk, and how to screen other children. Participants and their child will participate in a comprehensive assessment of child's brain development, thinking and behavior through completing tests and questionnaires. There is only one study visit of 1 to 1.5 hours with no follow-up required

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

1 year to 21 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Patients with hemophilia
Children and young adults with hemophilia A or B, all severities, treated in the hemophilia treatment center (comprehensive care) setting, including participation of caregivers/parents completing questionnaires designed to evaluate neurologic, neurocognitive and neurobehavioral function and development.
Other: No treatment given
The participants will undergo a brief physical examination focused on neurologic function (muscle function, sensation, coordination, walking). Parents will be asked by the study team or the psychologist about their children and will complete several commonly used standard surveys about brain development, thinking, behavior, and decision making. The participants will also engage with the psychologist to evaluate development or thinking (IQ), and depending on their age they may be asked to complete one or more commonly used standard surveys about behavior and decision making.
