About this study

Official title: Detection of Human Beta Cell Death in T1DM by Methylation Specific PCR

To investigate the use of methylation-specific PCR (MSP) assays to detect human beta cell-specific gene methylation patterns in serial blood samples drawn from newly diagnosed Type 1 diabetics.

Read the detailed description

The study will follow 25 newly diagnosed type 1 diabetic patients from the onset of symptoms to one year post-diagnosis. A total of 11 fasting blood draws will be taken, the first near the time of diabetes diagnosis, then 2 weeks later, monthly for the next 6 months, and every other month until 12 months. Each blood sample will be evaluated by the MSP assay, as well as for measurement of fasting plasma glucose, HbA1c, c-peptide, and autoantibodies. The study will also need 25 healthy volunteers to help us match some DNA markers needed for this data. Healthy volunteers will be se=matched healthy individuals who have one blood sample drawn.

What is being measured

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

  1. Develop sensitive, specific, and quantitative methylation- specific PCR assays for the detection of human beta cell-specific DNA methylation patterns cells and the onset of metabolic dysregulation.

    Measured: 1 year post diagnosis

  2. Use the assays to detect beta cell destruction throughout the early time-course of type 1 diabetes mellitus

    Measured: 1 year post diagnosis

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes Mellitus, run by City of Hope Medical Center at 2 sites 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 9 inclusion and 0 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 1 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

What does the primary outcome measure?

Develop sensitive, specific, and quantitative methylation- specific PCR assays for the detection of human beta cell-specific DNA methylation patterns cells and the onset of metabolic dysregulation. (time frame: 1 year post diagnosis). The study lists 2 primary outcomes in all. 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 NCT01176253, which also lists 8 linked publications.

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 1 May 2015.
