Comparative Effectiveness and Safety of Four Second Line Pharmacological Strategies in Type 2 Diabetes Study (CER-4-T2D) 781,430 Head-to-Head Comparison Observational

Active, not recruiting
Clinical Trial NCT05220917 (CER-4-T2D) is an observational study for Cardiovascular Events, Type2 Diabetes, Renal Disease that is active, not recruiting. It started on August 1, 2021 with plans to enroll 781,430 participants. Led by Brigham and Women's Hospital, it is expected to complete by July 1, 2026. The latest data from ClinicalTrials.gov was last updated on December 8, 2025.
Brief Summary
To perform an observational analysis to emulate a target trial (i.e., a hypothetical pragmatic trial that would have answered the causal question of interest) comparing the effectiveness and safety of sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide 1 receptor agonists (GLP-1RA), dipeptidyl peptidase-4 inhibitors (DPP-4i), and sulfonylureas (SU), at the class and individual agent level, in he...Show More
Detailed Description
Aim 1: (1a.) To evaluate the effectiveness of sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide 1 receptor agonists (GLP-1RA), dipeptidyl peptidase-4 inhibitors (DPP-4i), and sulfonylureas (SU), at the class and individual agent level, in head-to-head comparisons with respect to cardiovascular (CV) events, mortality, renal events, and other patient-centered outcomes (e.g., time spent at home),...Show More
