Many novel agents—many of them proven not only for DM management but also for the treatment of obesity with or without DM or heart failure (HF)—are now in development and may be added to the five classical pillars: other non-steroidal MRA (balcinrenone); aldosterone synthase inhibitors (baxdrostat and vicadrostat); other GLP-1 RA (tirzepatide, survodutide, retatrutide, and cagrilintide); ET1 R antagonists, (zibotentan); and soluble guanylate cyclase activators (avenciguat). The gene discussed is CYP11B2; the disease is diabetes mellitus.
