US FDA approves expanded use of Sanofi’s type 1 diabetes drug in children aged 8 to 17

NEW YORK – The US Food and Drug Administration (FDA) said on June 12 that it has approved the expanded use of Sanofi’s Type 1 diabetes injection in children aged eight to 17 years recently diagnosed with stage 3 of the condition.

The FDA had first approved the drug, Tzield, in 2022 to delay the progression of Type 1 diabetes from stage 2 to 3 in patients aged eight years and older. Its label was expanded over time.

In April, the regulator approved use of the drug to delay the progression to stage 3 in patients as young as one year of age.

The latest label expansion allows use of the drug in children recently diagnosed with stage 3 of the condition, with the aim of slowing down loss of insulin production.

Type 1 diabetes is a chronic condition in which the pancreas makes little or no insulin, with stage 3 patients experiencing symptoms such as frequent urination, excessive thirst and fatigue.

Stage 3 patients usually require insulin therapy to manage these symptoms.

Tzield works by targeting the immune response that damages insulin-producing cells in the pancreas, helping preserve the body’s own insulin production for longer.

The latest approval was based on a study of 328 children and teenagers who had been diagnosed within the past six weeks. Patients who received the drug had a smaller decline in insulin-producing cell function than those who received a placebo after about 18 months.

Tzield, however, has been under FDA scrutiny over safety concerns. The drug has a “boxed warning”, the FDA’s most prominent safety warning, after reports of serious, life-threatening cases of viral infections, including Epstein-Barr virus and cytomegalovirus. REUTERS
