The European Commission has approved Teizeild, the first disease-modifying therapy for type 1 diabetes in the EU, after studies showed it can delay disease progression by up to two years.
The European Commission has granted approval for Teizeild (teplizumab) to delay the progression to stage 3 type 1 diabetes (T1D) in adults and children aged eight years and older who have stage 2 T1D. The decision follows a positive recommendation from the European Medicines Agency’s Committee for Medicinal Products for Human Use.

Teizeild becomes the first disease-modifying therapy for type 1 diabetes to be approved in the European Union, representing a major advance in the management of this progressive autoimmune condition. The approval is supported by data from the TN-10 phase 2 clinical trial, which showed that treatment with Teizeild delayed the onset of stage 3 T1D by a median of two years compared to placebo in both adult and pediatric patients with stage 2 disease.
“We are pleased that, for the first time, we will be able to offer patients and families in the EU a disease-modifying therapy designed to address the underlying immune process of type 1 diabetes,” said Olivier Charmeil, Executive Vice President, General Medicines, Sanofi. “We remain committed to working with external stakeholders across the EU to bring patients the benefits of Teizeild, a unique therapy that may prevent the natural progression of type 1 diabetes by protecting beta-cell function.”
At the end of the TN-10 phase 2 study, the proportion of patients who remained in stage 2 T1D was almost twice as high in the Teizeild group as in the placebo group (57% vs 28%). The safety profile was consistent with the one observed in previous studies of Teizeild. The most frequently observed adverse events were blood or bone marrow-related (transient lymphopenia) in 75% of the participants and dermatologic or skin-related (rash) in 36% of the participants.
Teizeild (known as Tzield outside the EU) is also approved in the US, the UK, China, Canada, the Kingdom of Saudi Arabia, the United Arab Emirates, and Kuwait to delay the onset of stage 3 T1D in adults and children aged eight years and older with stage 2 T1D. As previously communicated, following the positive CHMP recommendation for this newly approved indication, Sanofi has decided not to progress with a second application for Teizeild in recently diagnosed stage 3 T1D at this time. Next steps are under evaluation. Other regulatory reviews are ongoing.
