Real-World Study of Patients With Type 1 Diabetes Treated With Teplizumab as Part of Managed Access Programs (MAPs)

Официальное название

A Real-World Retrospective Observational Study Characterizing Patients With Stage 2 Type 1 Diabetes Treated With Teplizumab as Part of Managed Access Programs (MAPs)

Обзор

This study is a multi-country, multi-center retrospective observational cohort study based on secondary data collected via chart review, with the aim of describing patient characteristics (including relevant comorbidities), monitoring and treatment practices related to Type 1 diabetes mellitus (T1D) progression, and time to T1D progression in participants who received teplizumab as part of Managed Access Programs (MAPs). This study design was chosen in order to gain rapid insight into the current use of teplizumab in clinical practice and the characteristics of patients who received the treatment.

Вмешательства

• Препарат Teplizumab

Критерии участия

Критерии включения

• Patient written or electronic 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 as part of MAPs.

Критерии исключения

• 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.
