About this study

Official title: Glycemic Control, Brain Structure and Cognition in Youth With T1DM

LO5 study: The investigators are inviting a new group of youth (ages 7-16) who have been recently diagnosed with type 1 diabetes and their non-diabetic siblings. These youth will complete cognitive tests and a MRI scan of the brain. This scan uses strong magnets to obtain pictures and does not involve any radiation or injections. The investigators will recruit patients within three months of their diagnosis date. The study entails 1 study visit that lasts 3.5 hours. Evening and weekend times are available. The investigators plan to enroll 135 participants.

HY5 study: The investigators are inviting a cohort of youth and young adults (ages 9-21) with type 1 diabetes and their non-diabetic siblings for a follow-up to a study they have already completed. This group of people will complete several memory and thinking tests along with several MRI scans of their brain, just as they did at their previous visits. The investigators plan to enroll 150 participants.

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes Mellitis and Cognition, run by Washington University School of Medicine at 1 site in United States.

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 14 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 2 Nov 2016. 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 United States. 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.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00879203, 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 2 Nov 2016.
