The European Medicines Agency (EMA) has recommended marketing authorisation in the EU for Teizeild (teplizumab), the first treatment proven to delay the onset of stage 3 type 1 diabetes in adults and children aged 8 and above with stage 2 disease.
Type 1 diabetes is an autoimmune condition in which the immune system destroys insulin-producing beta cells. Symptoms appear at stage 3, when daily insulin therapy becomes essential. Delaying progression to this stage offers a major benefit, especially for children. Currently, no approved therapies exist to delay the disease.
Teizeild is a monoclonal antibody that slows the immune attack on beta cells. It is administered once daily for 14 days via intravenous infusion.
Evidence comes from a placebo-controlled trial in 76 patients, showing:
• Median time to stage 3 diabetes: 50 months with Teizeild vs 25 months with placebo
• 45% of Teizeild-treated patients progressed to stage 3 vs 72% with placebo
• Additional studies confirmed better preservation of beta-cell function
The most common side effects were reduced white blood cell counts and rash. A small number of patients (2%) experienced cytokine release syndrome.
Teizeild received support under EMA’s PRIME scheme, reflecting its public health importance. The CHMP recommendation now moves to the European Commission for final approval.
