Type 1 diabetes is a disease that occurs when the immune system attacks and destroys the cells that make insulin. “The drug’s potential to delay clinical diagnosis of type 1 diabetes may provide patients with months to years without the burdens of disease.” “Today’s approval of a first-in-class therapy adds an important new treatment option for certain at-risk patients,” said John Sharretts, M.D., director of the Division of Diabetes, Lipid Disorders, and Obesity in the FDA’s Center for Drug Evaluation and Research. Food and Drug Administration approved Tzield (teplizumab-mzwv) injection to delay the onset of stage 3 type 1 diabetes in adults and pediatric patients 8 years and older who currently have stage 2 type 1 diabetes.
