ReviewIntegrating oral semaglutide into clinical practice in primary care: for whom, when, and how?
Oral semaglutide is the first US Food and Drug Administration-approved oral glucagon-like peptide-1 receptor agonist (GLP-1RA) for the treatment of type 2 diabetes (T2D). Prior articles within this supplement reviewed the PIONEER trial program, which demonstrated that oral semaglutide reduced glycated hemoglobin and body weight when given to patients with uncontrolled T2D on various background therapies, and had a safety profile consistent with subcutaneous GLP-1RAs. This article provides guidance on integrating oral semaglutide into clinical practice in primary care. ⋯ Those managing patients should be aware of the potential impact of these dosing conditions on concomitant medications. When counseling patients, it is important to discuss these administration instructions, realistic therapeutic expectations, and strategies for mitigation of gastrointestinal events. Oral semaglutide provides a new option for add-on to initial T2D therapy (or later in the treatment paradigm), with the potential to enable more patients to benefit from the improvements in glycemic control, reductions in body weight, and low risk of hypoglycemia afforded by GLP-1RAs.

ReviewClinical review of the efficacy and safety of oral semaglutide in patients with type 2 diabetes considered for injectable GLP-1 receptor agonist therapy or currently on insulin therapy.
Injectable therapies such as glucagon-like peptide-1 receptor agonists (GLP-1RAs) and insulin are high-efficacy options for people with type 2 diabetes (T2D) who require treatment intensification. In addition to high glycemic efficacy, GLP-1RAs offer weight loss benefits, and some agents have been shown to reduce cardiovascular risk. This article summarizes data from two clinical studies with the first oral GLP-1RA, oral semaglutide, in situations where injectable therapy is often considered, and provides guidance on use in primary care. ⋯ Oral semaglutide was associated with low proportions of patients experiencing severe or blood glucose-confirmed symptomatic hypoglycemia when added to oral glucose-lowering therapies, and did not increase the incidence of such events when added to insulin. The tolerability profile of oral semaglutide was consistent with that seen for injectable GLP-1RAs, with gastrointestinal side effects seen most frequently; most were transient and tended to occur during dose escalation. For patients requiring treatment intensification after oral therapy or as add-on to insulin, oral semaglutide provides effective glucose lowering and body weight loss, with low risk of hypoglycemia, thus broadening the range of therapeutic options for treatment of T2D in primary care.

ReviewClinical review of the efficacy and safety of oral semaglutide in patients with type 2 diabetes compared with other oral antihyperglycemic agents and placebo.
Oral semaglutide is a tablet formulation of a glucagon-like peptide-1 receptor agonist (GLP-1RA), recently approved in the USA and other countries. This paper reviews data from clinical trials (PIONEER 1, 2, 3, and 7) comparing oral semaglutide (once-daily doses of 3, 7, or 14 mg) with either once-daily placebo, empagliflozin 25 mg, or sitagliptin 100 mg. After 26 weeks in PIONEER 1, patients randomized to 3, 7, or 14 mg doses of oral semaglutide monotherapy had statistically significant reductions in glycated hemoglobin (HbA1c) of 0.9%, 1.2%, and 1.4%, respectively, versus 0.3% with placebo. ⋯ Severe or blood glucose-confirmed symptomatic hypoglycemia occurred infrequently with oral semaglutide and was seen most often in patients taking concomitant sulfonylureas. Findings from these trials indicate that the addition of oral semaglutide reduces HbA1c and body weight and is associated with a low risk of hypoglycemia. Oral semaglutide represents an additional option for treating people with type 2 diabetes in primary care, with the potential to expand the numbers of patients benefiting from GLP-1RAs beyond that currently seen with injectable formulations.
