Type 1 Diabetes TrialNet (TrialNet) is an international network of researchers who are exploring ways to prevent, delay and reverse the progression of type 1 diabetes. TrialNet was established in response to the Surgeon General's Report Healthy People 2000. This report identified diabetes as a national health objective for the Nation. In response to the report, Congress created the Diabetes Research Working Group (DRWG) to develop a plan for diabetes research. One recommendation of the DRWG was to conduct additional research studies (clinical trials) to prevent type 1 diabetes.
