Advances in insulin: a review of icodec as a novel once-weekly treatment for type 2 diabetes

Type 2 diabetes (T2D) is a chronic condition that requires not only a team-based approach but also substantial self-management by those affected. Patient-clinician barriers such as lack of educational resources, hesitancy in initiation of therapy, concerns over treatment-related side effects, frequency of dosing, and the establishment of treatment goals, can prevent a patient from achieving optimal glycemic management. Recently, advances in diabetes technology and insulin formulations have helped to address some of these concerns. Insulin icodec, the first once-weekly basal insulin analog, has demonstrated efficacy and safety comparable to traditional basal insulin formulations. Since clinicians and patients may benefit from a once-weekly therapy, this review sought to evaluate the potential clinical implications of insulin icodec. A literature search was performed using PubMed, Google Scholar, and ClinicalTrials.gov up to 31 January 2024. Key search terms such as
