Description of Patients With Type 1 Diabetes Treated With Teplizumab (TEPLI-REAL)

August 14, 2025 updated by: Sanofi

A Real-World Observational Study Characterizing Patients With Type 1 Diabetes Treated With Teplizumab

Type 1 diabetes mellitus (T1D) is a chronic autoimmune disease caused by the destruction of pancreatic β cells. T1D pathogenesis progresses through several stages: Stage 1 T1D includes the presence of β cell autoimmunity and thus presence of islet autoantibodies, without the presence of dysglycemia and symptoms. Stage 2 T1D includes the presence of islet autoantibodies and dysglycemia, also with no symptoms. Stage 3 T1D includes presence of islet autoantibodies, overt hyperglycemia, and symptoms; most patients with Stage 3 T1D meet standard diagnostic criteria for diabetes and require insulin treatment.

Teplizumab has been shown to delay progression to Stage 3 in participants at Stage 2 in a Phase 2 clinical trial, leading to subsequent approval in the United States of America (USA). Patients outside of the USA are able to receive the treatment through Pre-Registration Import Licenses and Managed Access Programs. The current study will collect data on the use of teplizumab in routine care, to better understand which patients received teplizumab and how these patients were managed after they received the treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients whose index date (teplizumab initiation date) was ≥ 6 weeks before site activation and who meet the eligibility criteria outlined below will be eligible for enrollment into the study.

Description

Inclusion Criteria:

  • Patient informed consent or assent (for patients < 18 years old) according to local regulations or appropriate informed consent waivers prior to any study related activity.
  • Patient received ≥ 1 day of teplizumab treatment.

Exclusion Criteria:

  • Participation in an interventional clinical study on the index date. Participation in an interventional clinical study is defined as initiating the product/procedure or control under investigation. An interventional clinical study is a study that requires deviation from standard clinical practice by following a study protocol.
