Summary
Brief summary (as posted)
This is a database linkage study utilizing real-world data (RWD) to determine whether certain medicines used to treat type 2 diabetes (T2D) and support weight management (called GLP-1 RAs (Glucagon-like peptide-1 receptor agonists )) are linked to an increased risk of a rare cancer called medullary thyroid carcinoma (MTC). The purpose of this study is to compare how often medullary thyroid cancer occurs in people taking these medicines versus those taking other similar treatments. This study will use dispensed prescription claims and State Cancer Registry data to assess the risk of MTC.
