Dear TrialNet Family,
As we announce the 2-year findings for the ATG-GCSF New Onset Study, I’d like to take a moment to give a big and well-deserved thank you to everyone who made this study possible:

This study was designed to build on prior findings of a pilot study suggesting thymoglobulin (ATG) combined with pegylated granulocyte colony stimulating factor (GCSF) preserved insulin production for more than 1 year after treatment in people who had type 1 diabetes for 4 months to 2 years.
ATG is approved by the Food and Drug Administration (FDA) for prevention and treatment of kidney transplant rejection. GCSF is an FDA-approved drug used to increase white blood cell counts in patients receiving chemotherapy.
TrialNet researchers wanted to know if ATG alone or in combination with GCSF could slow insulin loss when started earlier. To find out, we enrolled 89 people between ages 12 and 45 diagnosed with type 1 diabetes within the past 100 days.
Participants were divided into three groups: one group received ATG, one group received ATG combined with GCSF, and one group received a placebo (looks like the study drug but is inactive). Everyone participated in the study for 2 years.
“The fact that results are being maintained for 2 years is highly significant,” said Study Chair and TrialNet Investigator at University of Florida, Michael Haller, M.D. “Any approach that allows people with type 1 diabetes to produce more of their own insulin and maintain better blood glucose control for this long demonstrates progress towards our ultimate goal of preventing and reversing this terrible disease.”
"This project shows the power of collaboration in moving research forward," said Helmsley Type 1 Diabetes Program Director Gina Agiostratidou, Ph.D. "Thanks to long-term support from several groups, we're a step closer to using this knowledge to benefit people with type 1 diabetes."
In addition, TrialNet is continually planning and launching new studies. And, we always encourage family members of people with T1D to get screened through the Pathway to Prevention study.
A big thank you to our amazing participants who made this research possible!Your study team will be in touch shortly to go over your individual results.
