Ozempic is well-known for its reputation in mainstream media as a weight reduction drug. Nevertheless, it was (and nonetheless is) initially indicated to deal with diabetes mellitus. Ozempic is a part of a bunch of medicines referred to as glucagon-like peptide 1 receptor agonist (GLP1-RA for brief.) There have been claims of associations in premarketing research about an affiliation with GLP1-RAs and thyroid most cancers in rodents. Due to this affiliation, GLP1-RAs are contraindicated in sufferers with a historical past or household historical past of thyroid most cancers. They even have an FDA-issued black field warning, which is probably the most severe warning for medicines that the FDA points. This examine printed in the BMJ, performed within the Scandinavian international locations of Denmark, Norway, and Sweden, sought to dive deeper into this affiliation.
The researchers in contrast sufferers initiating GLP1 receptor agonists with these beginning dipeptidyl peptidase 4 (DPP4) inhibitors, a generally used comparator in diabetes remedy. Additionally they performed an extra evaluation evaluating GLP1 receptor agonists with sodium-glucose cotransporter 2 (SGLT2) inhibitors, one other common medicine utilized in diabetes remedy. The outcomes have been derived from nationwide most cancers registers, guaranteeing correct and acceptable knowledge assortment.
The primary findings of the examine indicated that GLP1 receptor agonist use was not considerably related to an elevated danger of thyroid most cancers over a median follow-up interval of three.9 years. Regardless of considerations raised from earlier analyses and pharmacovigilance knowledge, the examine discovered no substantial improve in danger even throughout totally different subtypes of thyroid most cancers.
Further analyses have been performed to make sure the robustness of the findings. These included assessments of various time intervals after remedy initiation, various definitions of drug use, and changes for potential confounders corresponding to calendar yr and former most cancers diagnoses. The outcomes remained constant throughout these analyses, additional supporting the principle conclusion that GLP1 receptor agonist use just isn’t considerably related to an elevated danger of thyroid most cancers.
The strengths of the examine lie in its massive, unselected examine inhabitants drawn from routine medical observe throughout three Scandinavian international locations. The excellent knowledge protection from nationwide registers and the usage of rigorous pharmacoepidemiologic strategies improve the reliability and generalizability of the findings.
The findings of this Scandinavian cohort examine counsel that GLP1 receptor agonist remedy just isn’t considerably related to an elevated danger of thyroid most cancers. These outcomes provide reassurance to healthcare suppliers and sufferers concerning the protection profile of GLP1 receptor agonists in relation to thyroid most cancers danger. Additional analysis could also be warranted to validate these findings and discover potential long-term results.
