Purpose: Glucagon-like peptide 1 receptor agonists (GLP1-RA) are effective therapies in lowering glycosylated hemoglobin (HbA1c), providing cardioprotective benefits, and lowering weight. The use of GLP1-RA solely for weight-loss has become commonplace in many practices, which in turn has made it difficult in some areas for those with type 2 diabetes (T2DM) to obtain these much-needed medications.
Methods: Using recent published literature, along with clinical experience, it has become apparent that many GLP1-RAs have become difficult to obtain for patients with diabetes.
Findings: Many clinicians started to prescribe the brand Ozempic® (semaglutide*) and dulaglutide for weight loss despite neither of them being Food and Drug Administration (FDA) approved for this indication. Ozempic, having outperformed dulaglutide in in both HbA1c reduction and weight loss, along with FDA approval of semaglutide for weight loss, has quickly become widely used off-label for weight loss. This off-label use may have increased, despite the approval of semaglutide,† because many insurances will not cover semaglutide solely for weight management. Most recently, Eli Lilly was able to develop tirzepatide,‡ which was FDA approved in May of 2022, and they are seeking fast-track FDA approval for weight loss and are projected to gain this approval within 2023.
Implications: Insurance coverage for weight management remains sparse, and obtaining these therapies for diabetes has now become more burdensome, with insurance companies requiring a prior authorization proving FDA-approved diagnosis of T2DM. Hopefully, should more GLP1-Ras receive approval for weight loss, along with an increase in insurance coverage, the burden on patients with diabetes will be lessened as they are able to quickly obtain this highly effective therapy.
