What is the Abatacept prevention trial?

The investigators carrying out this study are part of a research group called TrialNet that is studying type 1 diabetes. These investigators are testing an investigational drug, called abatacept [CTLA4], which is approved by the U.S. Food and Drug Administration as a treatment for rheumatoid arthritis and polyarticular juvenile idiopathic arthritis (JIA) in pediatric patients 6 years of age and older. In a previous TrialNet study, abatacept was shown to have some effect on preserving insulin secretion after diagnosis, which is why it is now being tested in prevention.

Who can participate?

  • Individuals who are 6 and older with two autoantibodies and normal glucose tolerance.
  • All participants are identified through the TrialNet Pathway to Prevention study.

What will study participants be asked to do?

This placebo-controlled study will have two phases, a treatment phase for the first year and then a monitoring phase. During the treatment phase, you will receive the study drug 14 times over the first year.  During the monitoring phase, you will have visits every six months.
