Abstract
AIM Oral semaglutide, an innovative orally administered GLP-1 receptor agonist for type 2 diabetes (T2D) management was herein evaluated for its effectiveness in a multi-center retrospective real-world study. METHODS We included new-users of oral semaglutide from 18 specialist care centres and collected retrospective data on baseline clinical characteristics. Updated values of HbA1c and body weight were analyzed using the mixed model for repeated measures. RESULTS The study included 166 individuals with T2D, predominantly men (64.5%), with a mean age of 64.4 years and a mean diabetes duration of 10.1 years. In the majority of patients (68.3%) oral semaglutide was used as a second-line drug, mostly with metformin. At baseline, mean BMI was 28.9 kg/m2 and HbA1c was 7.5%. During the 18-month observation period, oral semaglutide demonstrated significant reductions in HbA1c, with a maximum change of - 0.9%, and 42.1% of patients achieved HbA1c values below 7.0%. Additionally, there was a substantial reduction in body weight, with an estimated change of - 3.4 kg at 18 months, and 30.3% of patients experienced a 5% or greater reduction in baseline body weight. Only 24.2% of patients reached the 14 mg dose. Subgroup analysis revealed that baseline HbA1c > 7%, persistence on drug, not being on a prior therapy with DPP-4 inhibitors, and loosing 5% or more the initial body weight were associated with greater HbA1c reductions. CONCLUSION This study supports oral semaglutide as an effective option for T2D treatment, offering improved glucose control and weight management in a real-world setting.

Abstract
BACKGROUND/AIM In the SUSTAIN-6 trial, semaglutide reduced the risk of worsening nephropathy in patients with type 2 diabetes. The objective of this retrospective study was to elucidate the effect and safety of oral semaglutide (Rybelsus®) in patients with diabetic kidney disease (DKD). PATIENTS AND METHODS Six patients with DKD received 3 mg/day semaglutide orally. The observation period was 9.0±5.0 months. Changes in estimated glomerular filtration rate (eGFR), urinary protein, fasting blood glucose, and hemoglobin A1c were studied from 6 months before the administration of oral semaglutide until 6 months after administration. RESULTS The change in eGFR over the 6 months prior to semaglutide administration was -1.2±1.6 ml/min/1.73 m2, showing a trend for a decrease; although not statistically significant, the change at 6 months after oral semaglutide initiation showed improved eGFR (1-50.7±1.8 ml/min/1.73 m2). Proteinuria was not reduced after treatment with oral semaglutide. No significant adverse effects (including retinopathy) were observed in any patient during the study. CONCLUSION Despite the small sample size and short observation period, oral semaglutide was found to be a relatively well-tolerated drug for patients with DKD.

Abstract
OBJECTIVE To explore the effects of oral semaglutide on glycaemic parameters, body weight, and satisfaction in the first recipient patients with type 2 diabetes mellitus in Slovenia, in a real-world clinical practice setting. METHODS The first consecutive adult patients with type 2 diabetes who were eligible for oral semaglutide treatment were included in this prospective, open-label interventional study. Patients received increasing doses of oral semaglutide and were evaluated at inclusion, at 1 month, then 3-5 months after starting treatment. Fasting blood glucose, glycosylated haemoglobin (HbA1c), body weight, patient satisfaction with oral semaglutide treatment (using the validated Treatment Satisfaction Questionnaire for Medication), and adverse effects, were analysed. Statistical analyses were performed using one-way analysis of variance, and, when significant interactions were found, Bonferroni post-hoc test. A P-value <0.05 was considered statistically significant. RESULTS Twenty patients (11 male: 9 female; mean age, 59.9 ± 1.5 years; mean diabetes duration, 8.5 ± 1.4 years) were included. Oral semaglutide (7 and 14 mg) significantly decreased HbA1c (from 9.4 ± 0.3% to 8.2 ± 0.2% and 7.8 ± 0.2%, respectively) and fasting plasma glucose (from 11.2 ± 0.5 mmol/L to 9.2 ± 0.7 mmol/L and 8.9 ± 0.4 mmol/L, respectively). Oral semaglutide (14 mg) significantly decreased body weight (from 100.9 ± 2.7 kg to 92.7 ± 2.4 kg). Patients reported that treatment was easy to use and expressed high global satisfaction. Mild and transient, mostly gastrointestinal, adverse effects were reported in 10 patients. CONCLUSIONS Oral semaglutide, the first oral glucagon-like peptide 1 receptor agonist, was effective and safe, and associated with high patient satisfaction, in its first recipients in Slovenia. The results are important for daily clinical practice involving patients with type 2 diabetes, however, due to the small study population, lack of placebo control, and short exposure to oral semaglutide, the effectiveness of oral semaglutide in clinical practice requires further investigation.

Abstract
INTRODUCTION Given the lack of real-world data on oral semaglutide use outside clinical trials, the purpose of this study was to describe dose, prescriber specialty, and change in hemoglobin A1c (HbA1c) after 6 months of oral semaglutide treatment for patients with type 2 diabetes mellitus (T2DM). METHODS This was a retrospective study among adult patients with T2DM with ≥ 1 claim for oral semaglutide between November 1, 2019`1-June 30, 2020. Patients had continuous health plan enrollment ≥ 12 months prior to (pre-index) and ≥ 6 months following (post-index) the date of the first oral semaglutide claim (index). Dose at initiation and specialty of the prescribing provider were captured. Change in HbA1c between the last post- and pre-index HbA1c measurement was calculated. Patients were stratified by pre-index HbA1c ≥ 9% (poorly controlled) and HbA1c < 9%. RESULTS A total of 744 HbA1c < 9% and 268 poorly controlled patients were included in the study. Most patients had an initial oral semaglutide dose of 7 mg (49.3%) or 3 mg (42.9%), prescribed most frequently by a primary care provider (27.8%). Mean HbA1c reduction was 0.8% (p < 0.001). Patients with poorly controlled T2DM had greater HbA1c reductions than patients with HbA1c < 9% (2.0% versus 0.4%, p < 0.001). Patients persistent with oral semaglutide (≥ 90 days continuous treatment) had a mean HbA1c reduction of 0.9% (p < 0.001); persistent patients with poorly controlled T2DM had a mean reduction of 2.5%. CONCLUSIONS Patients with T2DM in this study experienced significant reductions in HbA1c within 6 months following initiation of oral semaglutide. Patients with a higher starting HbA1c experienced greater HbA1c reductions. The initial dose of oral semaglutide was higher than prescribing instructions indicated for more than half of the study patients.

Abstract
INTRODUCTION As new glucagon-like peptide 1 receptor agonist (GLP-1 RA) formulations are available, the aim of this study was to understand dulaglutide and subcutaneous (s.c.) semaglutide dosing patterns in people with type 2 diabetes mellitus (T2DM) in the UK and Germany as well as oral semaglutide in the UK. METHODS Adults with evidence of T2DM and a prescription of dulaglutide or semaglutide between August 2020 and December 2021 were identified using the IQVIA Longitudinal Prescription Data (LRx). Patients were divided into cohort 1 (incident users) and cohort 2 (prevalent users) based on previous exposure to GLP-1 RAs and were followed up to 12 months post-index. RESULTS During the patient selection window in Germany and the UK, 368,320 and 123,548 patients respectively received at least one prescription of a study GLP-1 RA. Among dulaglutide users in Germany at 12 months post-index, the 1.5-mg dosage formulation was the most common for both cohort 1 (65.6%) and 2 (71.2%). Among s.c. semaglutide users at 12 months post-index, 39.2% and 58.4% of cohort 1 received 0.5 mg and 1.0 mg, respectively. In the UK, at 12 months post-index, the most common dulaglutide dosage formulation was 1.5 mg (71.7% cohort 1 and 80.9% cohort 2). Among s.c. semaglutide users at 12 months post-index, 0.5- and 1.0-mg formulations were the most common for both cohort 1 (38.9% and 56.0%, respectively) and cohort 2 (29.5% and 67.1%, respectively). Prescribing of the more recently introduced 3.0- and 4.5-mg formulations for dulaglutide and oral semaglutide was also reported in the study. CONCLUSION Dosing patterns of GLP-1 RAs, although similar between the UK and Germany, were heterogeneous over time. Given that the higher dulaglutide doses and oral semaglutide were recently introduced to the market, additional real-world evidence studies which include clinical outcomes is required.

Abstract
Diabetic kidney disease, a common complication in patients with type 2 diabetes mellitus, is associated with a markedly increased morbidity and mortality, especially of cardiovascular origin, and faster progression to end-stage renal disease. To date, reducing cardiovascular and renal risk in this population was based on strict control of cardiovascular risk factors and the renin-angiotensin system blockade. More recently, sodium-glucose cotransporter type 2 inhibitors have demonstrated to offer cardiovascular and renal protection, but the residual risk remains high and their antihyperglycemic efficacy is limited in moderate-severe CKD. Therefore, drugs with a potent antihyperglycemic effect, independent of the glomerular filtration rate, with a low risk of hypoglycemia, that reduce weight in overweight/obese patients and that provide cardiovascular and renal protection, such as GLP-1 receptor agonists, are needed. However, these drugs require subcutaneous administration, which may limit their early use. The recent availability of oral semaglutide may facilitate the early introduction of this family with proven cardiovascular and renal benefits and excellent safety profile. In this review the family is analyzed as well as their cardiovascular and renal effects.

Abstract
Background Excessive body fat may be a major cause of insulin resistance and diabetes. But body weight reduction by energy restriction may simultaneously reduce both fat and muscle. Skeletal muscle is an important organ for glucose metabolism regulation, and loss of muscle may deteriorate glucose metabolism. Therefore, it is preferable to predominantly reduce fat without significant loss of muscle with weight loss in patients with type 2 diabetes. Previously, the anti-diabetic agent glucagon-like peptide-1 receptor agonists (GLP-1RAs) liraglutide and semaglutide given by injection were reported to decrease fat with less effect on muscle in diabetic patients. Recently oral semaglutide was developed and was reported to decrease body weight, but the effect on muscle has not been fully evaluated. Methods This was a non-interventional retrospective longitudinal study. We evaluated the effect of 24-week treatment with oral semaglutide on body fat and muscle mass in 25 Japanese patients with type 2 diabetes. Laboratory examination and body composition test by bioelectrical impedance analysis (BIA) were performed at baseline, 12 weeks, and 24 weeks, and the effects on glycemic control and body composition were assessed. Results Hemoglobin A1c significantly decreased at 12 weeks and further ameliorated at 24 weeks (8.7±0.87% at baseline; 7.6±1.00% at 12 weeks; 7.0±0.80% at 24 weeks; mean ± standard error (SE)). While body fat significantly decreased (28.3 ± 1.52 kg at baseline; 26.8 ± 1.59 kg at 12 weeks; 25.5 ± 1.57 kg at 24 weeks; mean ± SE), whole-body lean mass was not significantly changed (48.1 ± 1.92 kg at baseline; 47.7 ± 1.93 kg at 12 weeks; 47.6 ± 1.89 kg at 24 weeks; mean ± SE). Furthermore, the appendicular skeletal muscle index (SMI) defined as appendicular skeletal muscle mass (ASM)/height squared (units; kg/m2) was also unchanged. Conclusion The 24-week treatment with oral semaglutide ameliorated glycemic control with reduction of body fat but not muscle mass in Japanese patients with type 2 diabetes.

Abstract
OBJECTIVES To investigate the efficacy and safety of oral semaglutide 7 and 14 mg, the only orally delivered glucagon-like peptide-1 (GLP-1) receptor agonist tablet approved for type 2 diabetes mellitus (T2DM) patients. METHODS Search several databases for randomized controlled trials (RCTs) of oral semaglutide in patients with T2DM from inception through May 31, 2021. The primary outcomes included change from baseline in hemoglobin A1c (HbA1c) and body weight. Risk ratios (RR), mean differences (MD), and 95% confidence intervals (CI) were calculated to evaluate the outcomes. RESULTS This meta-analysis included 11 RCTs with a total of 9821 patients. Compared with placebo, semaglutide 7 and 14 mg reduced HbA1c by 1.06% (95% CI, 0.81-1.30) and 1.10% (95% CI, 0.88-1.31), respectively. While in comparison with other antidiabetic agents, semaglutide 7 and 14 mg reduced HbA1c by 0.26% (95% CI, 0.15-0.38) and 0.38% (95%CI, 0.31-0.45). Both doses of semaglutide could significantly reduce body weight. Semaglutide 14 mg did increase the incidence of medication discontinuation and gastrointestinal events (nausea, vomiting and diarrhea). CONCLUSION Once-daily semaglutide 7 and 14 mg can significantly lowered HbA1c and body weight in patients with T2DM, and this effect increases with dose. Significantly, more gastrointestinal events occurred with semaglutide 14 mg.

Abstract
INTRODUCTION Novel glucagon-like peptide-1 (GLP-1) receptor agonist oral semaglutide has demonstrated greater improvements in glycated hemoglobin (HbA1c) and body weight versus oral medications empagliflozin and sitagliptin, and injectable GLP-1 analog liraglutide, in the PIONEER clinical trial program. Based on these data, the present analysis aimed to evaluate the long-term cost-effectiveness of oral semaglutide versus empagliflozin, sitagliptin and liraglutide in Spain. METHODS Outcomes were projected over patients' lifetimes using the IQVIA CORE Diabetes Model (v9.0), discounted at 3.0% annually. Cohort characteristics and treatment effects were sourced from PIONEER 2 and 4 for the comparisons of oral semaglutide 14 mg versus empagliflozin 25 mg and liraglutide 1.8 mg, respectively, and PIONEER 3 for oral semaglutide 7 and 14 mg versus sitagliptin 100 mg. Costs were accounted from a healthcare payer perspective in 2020 euros (EUR). Patients were assumed to receive initial therapies until HbA1c exceeded 7.5% and then treatment-intensified to basal insulin. RESULTS Oral semaglutide 14 mg was associated with improvements in quality-adjusted life expectancy of 0.13, 0.19 and 0.06 quality-adjusted life years (QALYs) versus empagliflozin 25 mg, sitagliptin 100 mg and liraglutide 1.8 mg, respectively, with direct costs EUR 168 higher versus empagliflozin and EUR 236 and 1415 lower versus sitagliptin and liraglutide, respectively. Oral semaglutide 14 mg was associated with an incremental cost-effectiveness ratio (ICER) of EUR 1339 per QALY gained versus empagliflozin and was considered dominant (clinically superior and cost saving) versus sitagliptin and liraglutide. Additional analyses demonstrated that oral semaglutide 7 mg was associated with improvements of 0.11 QALYs and increased costs of EUR 226 versus sitagliptin and was therefore associated with an ICER of EUR 2011 per QALY gained. CONCLUSION Oral semaglutide 14 mg was dominant versus sitagliptin and liraglutide, and cost-effective versus empagliflozin, for the treatment of type 2 diabetes in Spain.

Abstract
BACKGROUND Semaglutide, a glucagon-like peptide-1 receptor agonist (GLP1a), reduces the risk of major adverse cardiovascular events (MACE) in patients with Type 2 diabetes mellitus (T2DM). An oral version of semaglutide is now available, and patients may prefer it over the subcutaneous form. Our objective was to compare the value for money of the two modalities by assessing the cost needed to treat (CNT) to prevent MACE. METHODS The CNT to prevent MACE was figured by multiplying the one-year number needed to treat (NNT) with either oral or subcutaneous semaglutide by the annual cost of therapy. Efficacy estimates and the resulting NNT figures were extracted from the published results of the SUSTAIN-6 and the PIONEER-6 trials for the injectable and oral versions of semaglutide, respectively. Drug costs were estimated as 75% of the United States national average drug acquisition cost listing in June 2021. We performed a scenario analysis to mitigate the primary differences between the populations in the two trials. Sensitivity analysis was performed to evaluate the effect of price changes of the interventions. RESULTS The CNT to prevent one MACE with subcutaneous semaglutide in SUSTAIN-6 was $966,693 ($594,888-$5,035,302) compared to $948,689 ($463,465-∞) with oral semaglutide in PIONEER-6. The scenario analysis demonstrated a 17% lower CNT for oral semaglutide. The difference between CNTs was sensitive to price fluctuations of the two interventions. CONCLUSIONS Oral and subcutaneous semaglutide prescribed to prevent MACE in patients with T2DM provide similar value for money. The choice between both therapies should be guided mainly by patient preferences.

Abstract
AIMS Despite their established benefits, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) remain underutilized for type 2 diabetes mellitus (T2DM) management, which indicates that subcutaneous injection is an unfavorable mode of delivery from the patient's perspective. This review summarizes existing challenges related to medication adherence and the use of antihyperglycemia injectables, revisits the established safety and efficacy of oral semaglutide, and explores its features and considerations for use among the Indian T2DM population. METHODS We performed a literature search using MEDLINE and the National Institutes of Health Clinical Trials Registry from July 1, 2016, to July 1, 2021, to identify publications on oral semaglutide approval, T2DM treatment guidelines, and clinical evidence for oral drug formulation. RESULTS Oral semaglutide is the first oral GLP-1 RA approved for T2DM patients based on phase 3, randomized PIONEER trials. The multitargeted action of this drug offers glycemic control, weight control, and cardiovascular, renal, and additional benefits, including patient convenience and enhanced medication adherence. In addition to achieving glycemic control, the cost of semaglutide is reported to be lower than other GLP-1 RA in the West, thus potentially mitigating the economic burden that appears to be high among the Indian population. CONCLUSIONS Currently, there is no data available on oral semaglutide in Indian clinical settings. However, significant improvements in glycemic control, cardiac and renal benefits, as well as weight loss across clinical trials should encourage clinicians to prioritize oral semaglutide over other antidiabetic agents.

Abstract
BACKGROUND AND AIMS Oral semaglutide is the first glucagon-like petide-1 receptor agonist (GLP-1RA) approved for oral use in the treatment of type 2 diabetes mellitus (T2DM). We aim to conduct a comprehensive review of literature to find out the efficacy and safety of oral semaglutide in T2DM, to lay out a clinical consideration for its use in India. METHODS We searched the electronic database of PubMed and Google Scholar from inception until January 31, 2022, using several MeSH keywords and retrieved all available granular details of phase 1, 2 and 3 randomized controlled trials (RCTs) of oral semaglutide. Subsequently, we reviewed the results critically to lay down the clinical recommendation of its use. RESULTS Ten phase 3 randomized, placebo- and or active-controlled studies of oral semaglutide (PIONEER programs) are currently published. Seven global trials of oral semaglutide (PIONEER 1-5, 7 and 8) that exclusively studied the efficacy (lowering of HbA1c and body weight, achieving target of HbA1c <7% and other composites of HbA1c and weight) outcomes, found 14 mg oral semaglutide to be superior to placebo or active comparators (empagliflozin, sitagliptin and liraglutide). Efficacy was similar in Asians, although no separate data exists for Indians due to the low number of participants. Expectedly, gastrointestinal intolerance were the most commonly observed side effects with oral semaglutide and the main reason for drug discontinuation. CONCLUSION Oral semaglutide 14 mg is an effective agent in the treatment of T2DM. Real-world studies of semaglutide are clearly needed in India in absence of meaningful data from RCTs in Indians.

Abstract
BACKGROUND Oral semaglutide is a novel glucagon-like peptide-1 (GLP-1) analog that has been associated with improvements in glycated hemoglobin (HbA1c) and body weight versus sodium-glucose cotransporter-2 inhibitor empagliflozin and injectable GLP-1 receptor agonist dulaglutide in the PIONEER 2 clinical trial and in a recent network meta-analysis (NMA), respectively. The aim of the present study was to evaluate the long-term cost-effectiveness of oral semaglutide 14 mg versus empagliflozin 25 mg and dulaglutide 1.5 mg for the treatment of type 2 diabetes from a healthcare payer perspective in Portugal. METHODS In two separate analyses, outcomes were projected over patients' lifetimes using the IQVIA CORE Diabetes Model (v9.0), discounted at 4% per annum. Clinical data were sourced from the PIONEER 2 trial and the NMA for the comparisons versus empagliflozin and dulaglutide, respectively. Patients were assumed to receive initial therapies until HbA1c exceeded 7.5%, then treatment-intensified to solely basal insulin therapy. Costs were accounted from a National Healthcare Service perspective in Portugal and expressed in 2021 euros (EUR). Utilities were taken from published sources. RESULTS Oral semaglutide 14 mg was associated with improvements in life expectancy of 0.10 and 0.03 years, and quality-adjusted life expectancy of 0.11 and 0.03 quality-adjusted life years (QALYs), versus empagliflozin 25 mg and dulaglutide 1.5 mg, respectively. Improved clinical outcomes were due to a reduced cumulative incidence and increased time to onset of diabetes-related complications with oral semaglutide. Total costs were projected to be EUR 2548 and EUR 814 higher with oral semaglutide versus empagliflozin and dulaglutide, with higher acquisition costs partially offset by cost savings from avoidance of diabetes-related complications. Oral semaglutide 14 mg was therefore associated with incremental cost-effectiveness ratios of EUR 23,571 and EUR 23,927 per QALY gained versus empagliflozin 25 mg and dulaglutide 1.5 mg, respectively. CONCLUSIONS Based on a willingness-to-pay threshold of EUR 30,000 per QALY gained, oral semaglutide 14 mg was considered cost-effective versus empagliflozin 25 mg and dulaglutide 1.5 mg for the treatment of type 2 diabetes in Portugal.

Abstract
While glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, are among the most effective drugs for treating people with type 2 diabetes (T2D), they are clinically under-utilised. Until recently, the only route for semaglutide administration was via subcutaneous injection. However, an oral formulation of semaglutide was recently licensed, with the potential to address therapy inertia and increase patient adherence to treatment, which is essential in controlling blood glucose and reducing complications. The availability of oral semaglutide provides a new option for both clinicians and patients who are reluctant to use an injectable agent. This has been of particular importance in addressing the challenge of virtual diabetes care during the COVID-19 pandemic, circumventing the logistical problems that are often associated with subcutaneous medication administration. However, there remains limited awareness of the clinical and economic value of oral semaglutide in routine clinical practice. In this article, we present our consensus opinion on the role of oral semaglutide in routine clinical practice and discuss its value in reducing the burden of delivering diabetes care in the post-COVID-19 pandemic period of chronic disease management.

Abstract
Cardiovascular events related to atherosclerosis are responsible for high morbidity and mortality among patients with type 2 diabetes. Improvement in care, especially in early stages, is crucial. Oral semaglutide, a glucagon-like peptide 1 analogue, controls blood glucose and results in significant body weight loss in patients with type 2 diabetes. Beyond these well-known effects, an interesting aspect of this drug is its antiatherogenic activity, which should be further explored in clinical practice. This paper reviews the evidence related to oral semaglutide decreasing cardiovascular risk in patients with type 2 diabetes, focusing on the drug's antiatherosclerotic properties. The glucagon-like peptide 1 analogue restores endothelial dysfunction, induces vasodilatation, and reduces plasma lipids. Oral semaglutide showed cardiovascular safety profile, with significant reduced risk of death from cardiovascular events. Based on current data, clinicians should consider oral semaglutide for type 2 diabetes management.

Abstract
Background A meta-analysis is presented of cardiovascular outcome trials (CVOTs) comparing glucagon-like peptide-1 receptor agonists (GLP-1RA) versus placebo on cardiorenal outcomes in patients with type 2 diabetes mellitus (T2DM). Methods We did an electronic search up to June 30, 2021, for eligible trials. We did a meta-analysis of available trial data using a random-effects model to calculate overall hazard ratios (HRs) and 95% CI (confidence intervals). We included data from 8 CVOTs and 60,080 patients (72.4% with established cardiovascular disease). Results GLP-1RA reduced major cardiovascular events (MACE) by 14% (HR = 0.86, 95% CI 0.79–0.94, P = 0.006) with a non-significant heterogeneity between subgroups of patients with and without cardiovascular disease (P = 0.127). GLP-1RA also reduced the risk of cardiovascular death by 13% (P = 0.016), nonfatal stroke by 16% (P = 0.007), hospitalization for heart failure by 10% (P = 0.023), all-cause mortality by 12% (P = 0.012), and the broad composite kidney outcome by 17% (P = 0.012), which was driven by a reduction in macroalbuminuria only (HR = 0.74, 0.67–0.82, P < 0.001). Conclusions GLP-1RA have moderate benefits on MACE, and also reduce hospitalization for heart failure and all-cause mortality; they also have robust benefits on reducing the incidence of macroalbuminuria.

Abstract
BACKGROUND There is currently a large arsenal of antidiabetic drugs available to treat type 2 diabetes (T2D). However, this is a serious chronic disease that affects millions of adults worldwide and is responsible for severe complications, comorbidities, and low quality of life when uncontrolled due mainly to delays in initiating treatment or inadequate therapy. This review article aims to clarify the therapeutic role of the oral formulation of the glucagon-like peptide 1 receptor agonist (GLP-1 RA) semaglutide in treating typical T2D patients. The discussion focused on metabolic, glycemic, and weight alteration effects and the safety of the therapy with this drug. MAIN TEXT Therapy with glucagon-like peptide 1 receptor agonist (GLP-1 RA) promotes strategic changes in the pathophysiological pathway of T2D and improves the secretion of glucagon and insulin, which results in a reduction in blood glucose levels and the promotion of weight loss. Until recently, the only route for semaglutide administration was parenteral. However, an oral formulation of GLP-1 RA was recently developed and approved by the Brazilian Health Regulatory Agency (ANVISA) and the Food and Drug Administration (FDA) based on the Peptide Innovation for Early Diabetes Treatment (PIONEER) program results. A sequence of 10 clinical studies compared oral semaglutide with placebo or active standard-of-care medications (empagliflozin 25 mg, sitagliptin 100 mg, or liraglutide 1.8 mg) in different T2D populations. CONCLUSIONS Oral semaglutide effectively reduces glycated hemoglobin (HbA1c) levels and body weight in a broad spectrum of patients with T2D and shows cardiovascular safety. Oral semaglutide broadens therapy options and facilitates the adoption of earlier GLP-1 RA treatment once T2D patients present low rates of treatment discontinuation. The main adverse events reported were related to the gastrointestinal tract, common to GLP-1 RA class drugs.

Abstract
INTRODUCTION Oral semaglutide is a novel tablet formulation of the human glucagon-like peptide-1 analogue semaglutide. In two trials, the effects of prior food ingestion (food effect), post-dose fasting period and water volume with dosing (dosing conditions) on oral semaglutide pharmacokinetics were investigated. METHODS Subjects received once-daily oral semaglutide for 10 days. In the food-effect trial, 78 healthy subjects were randomised 1:1:1 to fed (meal 30 min pre-dose; 240 mL water with dosing), fasting (overnight until 4 h post-dose; 240 mL) or reference (fasting overnight until 30 min post-dose; 120 mL) arms. In the dosing conditions trial, 161 healthy men were randomised into eight dosing groups (overnight fasted with 50/120 mL water and 15/30/60/120 min post-dose fasting). Semaglutide plasma concentrations were measured frequently until 504 h after the 10th dose. RESULTS In the food-effect trial, limited or no measurable semaglutide exposure was observed in the fed arm, while all subjects in the fasting arm had measurable semaglutide exposure. Area under the semaglutide concentration-time curve (AUC0-24h,semaglutide,day10) and maximum semaglutide concentration (Cmax,semaglutide,day10) were numerically greater by approximately 40% for the fasting versus reference arm (p = 0.082 and p = 0.080, respectively). In the dosing conditions trial, AUC0-24h,semaglutide,day10 and Cmax,semaglutide,day10 were not different between water volumes (p = 0.541 and p = 0.676), but increased with longer post-dose fasting (p < 0.001). CONCLUSION Administration of oral semaglutide in the fasting state with up to 120 mL water and at least 30 min post-dose fasting results in clinically relevant semaglutide exposure. These dosing conditions have been used in the oral semaglutide phase 3 trials and are part of the approved label. TRIAL REGISTRATION ClinicalTrials.gov identifiers NCT02172313, NCT01572753.

Abstract
AIMS To assess the long-term cost-effectiveness of novel glucagon-like peptide-1 (GLP-1) analog oral semaglutide versus sodium-glucose cotransporter-2 inhibitor empagliflozin, dipeptidyl peptidase-4 inhibitor sitagliptin and injectable GLP-1 analog liraglutide in the Netherlands, based on the results of the PIONEER clinical trials. METHODS Outcomes were projected over patient lifetimes using the IQVIA CORE Diabetes Model. Clinical data were derived from PIONEER 2, 3 and 4. Patients were assumed to receive initial treatments until glycated hemoglobin exceeded 7.5%, then treatment-intensified to basal insulin therapy. Costs were accounted from a societal perspective in 2019 euros (EUR). RESULTS Oral semaglutide 14 mg was associated with improvements in quality-adjusted life expectancy of 0.15, 0.22 and 0.09quality-adjusted life years (QALYs) versus empagliflozin 25 mg, sitagliptin 100 mg and liraglutide 1.8 mg, respectively, with combined costs EUR1,032 higher, EUR115 higher and EUR1,267 lower. Oral semaglutide was therefore associated with incremental cost-effectiveness ratios of EUR7,061 and EUR516 per QALY gained versus empagliflozin and sitagliptin, respectively. CONCLUSIONS Based on long-term projections, oral semaglutide 14 mg was considered cost-effective versus empagliflozin 25 mg and sitagliptin 100 mg and dominant versus liraglutide 1.8 mg for the treatment of type 2 diabetes in the Netherlands.

Abstract
INTRODUCTION The efficacy and safety of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, were investigated in patients with type 2 diabetes (T2D) in the Peptide InnOvatioN for Early diabEtes tReatment (PIONEER) programme. The current post-hoc exploratory subgroup analyses evaluated outcomes by background medication and insulin regimen subgroups. METHODS Data from patients in the PIONEER 3-5, 7 and 8 trials receiving once-daily oral semaglutide (14 mg/flexibly dosed) or a comparator (placebo, sitagliptin 100 mg or liraglutide 1.8 mg) were analysed for efficacy (glycated haemoglobin [HbA1c] and body weight changes from baseline to planned end of treatment) and safety outcomes. Patients were grouped according to background medication (metformin, sulphonylurea, thiazolidinedione, sodium-glucose cotransporter-2 inhibitor, insulin, or combinations thereof). Efficacy outcomes were analysed using the trial product estimand (which assumes that patients remained on the trial product without rescue medication use). A separate analysis by background insulin regimen (basal, premixed or basal-bolus) was done for PIONEER 8 using the treatment policy estimand (regardless of trial product discontinuation or rescue medication use). Safety outcomes were analysed descriptively for all patients. RESULTS In total, 2836 patients receiving oral semaglutide 14 mg/flexibly dosed or comparators were included. Baseline characteristics were generally similar across background medication subgroups within each trial. Diabetes duration tended to be longer in patients receiving more background medications. Greater HbA1c and body weight reductions were seen across background medication subgroups with oral semaglutide (changes from baseline: - 1.0 to - 1.5% and - 2.2 to - 5.0 kg, respectively) than with comparators (except for similar HbA1c reductions vs liraglutide). There were no statistically significant interactions by treatment and background medication subgroup for change in HbA1c or body weight except for change in HbA1c (background insulin vs insulin plus metformin) in PIONEER 8 (p = 0.0408). Changes in HbA1c and body weight were generally similar across insulin regimen subgroups, without significant treatment interactions by subgroup, and the total daily insulin dose was decreased for patients receiving oral semaglutide. The incidence of adverse events was generally similar in background medication subgroups. CONCLUSION Oral semaglutide was effective at lowering HbA1c and body weight, regardless of background medications, and appears suitable for a broad range of patients with T2D in combination with other glucose-lowering agents. TRIAL REGISTRATION Clinicaltrials.gov: NCT02607865 (PIONEER 3), NCT02863419 (PIONEER 4), NCT02827708 (PIONEER 5), NCT02849080 (PIONEER 7) and NCT03021187 (PIONEER 8).

Abstract
OBJECTIVES To evaluate the efficacy and safety of the glucagon-like peptide-1 (GLP-1) receptor agonist (RA) oral semaglutide in the treatment of type 2 diabetes mellitus (T2DM) patients. METHODS Randomized controlled trials comparing oral semaglutide with placebo or other antihyperglycemic agents in T2DM patients were identified by searching PubMed, Embase, Cochrane Library and ClinicalTrials.gov. Risk ratios and mean differences with 95% confidence intervals were used to synthesize the results. RESULTS Ten relevant studies involving 8,536 patients were finally included. Compared with placebo, oral semaglutide significantly reduced hemoglobin A1c (HbA1c), body weight, fasting plasma glucose, self-measured plasma glucose (SMPG), serious adverse events and all-cause death and significantly increased the number of participants who achieved HbA1c < 7.0%. Compared with active comparators, oral semaglutide significantly reduced the level of HbA1c, body weight, and SMPG and significantly increased the number of participants who achieved HbA1c < 7.0%. Compared with placebo or active comparators, oral semaglutide did not increase the incidence of adverse events, hypoglycemia (severe or blood glucose-confirmed symptomatic), myocardial infarction, heart failure requiring hospitalization, stroke or acute pancreatitis but did increase the incidence of nausea, diarrhea and vomiting. CONCLUSIONS Oral semaglutide has favorable efficacy and safety in the treatment of T2DM patients. Oral semaglutide may be superior to liraglutide, dulaglutide, empagliflozin and sitagliptin for T2DM patients who have obesity or poor adherence to injectable GLP-1 RAs.

Abstract
GLP-1 receptor agonists (GLP-1RAs) are recommended for patients with type 2 diabetes (T2D), particularly those at high cardiovascular risk. Oral semaglutide is the first oral GLP-1RA. In clinical trials, oral semaglutide 14 mg reduced mean HbA1c by approximately 1.1-1.5% and reduced body weight by up to 5 kg. These changes were significantly greater compared with empagliflozin, sitagliptin and liraglutide (p < 0.05 for estimated treatment differences at 52 weeks in patients on treatment without rescue medication use). The most common side effects were gastrointestinal, mainly mild-to-moderate and transient nausea. Oral semaglutide may change the paradigm of T2D treatment in primary care.

Abstract
According to current guidelines, glucagon-like peptide-1 (GLP-1) receptor agonists are the antidiabetic agent of choice in patients with type 2 diabetes mellitus (T2DM) and established cardiovascular disease (CVD) and are also the preferable antidiabetic agent in patients with T2DM without CVD but with indicators of high cardiovascular risk. A limitation in the use of GLP-1 receptor agonists is that they are delivered by subcutaneous injections. In this context, the development of an orally administered formulation of semaglutide offers an additional option in the management of patients with T2DM. In the present review, we discuss the findings of the main trials that evaluated the safety and efficacy of oral semaglutide. Oral semaglutide appears to be more effective in reducing HbA1c levels and body weight than other antidiabetic agents and similarly effective to other GLP-1 receptor agonists. The safety profile of oral semaglutide is also comparable with other members of its class. Even though oral semaglutide did not reduce the incidence of the composite primary endpoint in a randomized controlled trial, a reduction in cardiovascular and all-cause mortality was observed. Therefore, oral semaglutide appears to represent a useful tool in the management of patients with TD2M, particularly those with established CVD or high cardiovascular risk and unwilling to receive injectable GLP-1 receptor agonists.

Abstract
BACKGROUND Semaglutide is a glucagon-like peptide-1 (GLP-1) analog treatment for type 2 diabetes (T2D) available in subcutaneous (s.c.) and oral formulations. Two cardiovascular (CV) outcomes trials showed that in subjects with T2D at high risk of CV events there were fewer major adverse CV events (MACE; defined as CV death, non-fatal stroke, non-fatal myocardial infarction) with semaglutide than with placebo (hazard ratio [95% CI]: 0.74 [0.58;0.95] for once-weekly s.c. semaglutide and 0.79 [0.57;1.11] for once-daily oral semaglutide). However, there is little evidence for an effect of semaglutide on MACE in subjects not at high risk of CV events. This post hoc analysis examined CV effects of semaglutide in subjects across a continuum of baseline CV risk. METHODS Data from the s.c. (SUSTAIN) and oral (PIONEER) semaglutide phase 3a clinical trial programs were combined according to randomized treatment (semaglutide or comparators) and analyzed to assess time to first MACE and its individual components. A CV risk model was developed with independent data from the LEADER trial (liraglutide vs placebo), considering baseline variables common to all datasets. Semaglutide data were analyzed to assess effects of treatment as a function of CV risk predicted using the CV risk prediction model. RESULTS The CV risk prediction model performed satisfactorily when applied to the semaglutide data set (area under the curve: 0.77). There was a reduced relative and absolute risk of MACE for semaglutide vs comparators across the entire continuum of CV risk. While the relative risk reduction tended to be largest with low CV risk score, the largest absolute risk reduction was for intermediate to high CV risk score. Similar results were seen for relative risk reduction of the individual MACE components and also when only placebo comparator data were included. CONCLUSION Semaglutide reduced the risk of MACE vs comparators across the continuum of baseline CV risk in a broad T2D population.

Abstract
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. Patient populations with T2D who may gain benefit from oral semaglutide include those with inadequate glycemic control taking one or more oral glucose-lowering medication (e.g. after metformin), patients for whom weight loss would be beneficial, patients at risk of hypoglycemia, those who would historically have been considered for treatment with a subcutaneous GLP-1RA, and those receiving basal insulin who require treatment intensification. Like other GLP-1RAs, oral semaglutide is contraindicated in those with personal/family history of medullary thyroid carcinoma, and in those with multiple endocrine neoplasia syndrome type 2, as noted in a boxed warning in the prescribing information. Oral semaglutide has not been studied in those with a history of pancreatitis, is not recommended in patients with suspected/confirmed pancreatitis, and is not indicated in type 1 diabetes. When initiating oral semaglutide, gradual dose escalation is recommended to minimize the risk of gastrointestinal adverse events. As food and excess liquid reduce oral semaglutide absorption, patients should swallow the tablet with up to 4 fl oz/120 mL of water on an empty stomach upon waking, and should wait at least 30 minutes before eating, drinking, or taking other oral medications. 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.

Abstract
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. PIONEER 4 compared oral semaglutide 14 mg with an injectable GLP-1RA, liraglutide 1.8 mg, or placebo in patients uncontrolled on oral glucose-lowering therapies. PIONEER 8 compared oral semaglutide with placebo in patients with T2D already on insulin therapy. Treatment with oral semaglutide gave similar reductions in glycated hemoglobin (HbA1 c) compared with liraglutide at 26 weeks, and significantly greater reductions at 52 weeks. Changes in body weight with oral semaglutide were significantly greater compared with liraglutide after 26 and 52 weeks. Adding oral semaglutide 7 or 14 mg to insulin resulted in significant reductions in HbA1 c and body weight at both 26 and 52 weeks compared with placebo, and facilitated a decrease in total daily insulin dosage. 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.

Abstract
INTRODUCTION International guidelines recommend treatment with a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or glucagon-like peptide-1 (GLP-1) receptor agonist for treatment intensification in type 2 diabetes mellitus (T2DM) patients with progression on metformin. In the randomised, controlled, Peptide Innovation for Early Diabetes Treatment (PIONEER) 2 trial, the SGLT-2 inhibitor empagliflozin was compared with the GLP-1 receptor agonist oral semaglutide, in addition to metformin. The aim of the current study was to assess the long-term cost-effectiveness of empagliflozin 25 mg versus oral semaglutide 14 mg, in addition to metformin, for T2DM patients in the UK. METHODS Analyses were conducted from the UK healthcare payer perspective, using the IQVIA Core Diabetes model, with a time horizon of 50 years. Patients received either empagliflozin or oral semaglutide, in addition to metformin, until Hba1c threshold of 7.5% (58 mmol/mol) was exceeded, following which treatment intensification with insulin glargine in addition to empagliflozin or oral semaglutide plus metformin was assumed. Baseline cohort characteristics and 52-week treatment effects were derived from the PIONEER 2 trial. Treatment effects of empagliflozin and GLP-1 receptor agonists on hospitalisation for heart failure (hHF) were based on the Empagliflozin Comparative Effectiveness and Safety (EMPRISE) real-world study. Utilities, treatment costs and costs of diabetes-related complications were obtained from published sources. RESULTS Direct costs for empagliflozin plus metformin were considerably lower than those for oral semaglutide plus metformin (by more than GBP 6000). Compared with oral semaglutide plus metformin, empagliflozin plus metformin was a cost-effective treatment for T2DM patients in all scenarios tested. Probabilistic sensitivity analysis showed cost-effectiveness in > 95% of the iterations using a threshold of 20,000 GBP/QALY. CONCLUSION Empagliflozin 25 mg is a cost-effective treatment option versus oral semaglutide 14 mg, when used in addition to metformin, for the treatment of T2DM patients in the UK.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1RA) are effective agents for achieving glycemic control. Oral semaglutide is the first oral formulation of a GLP-1RA to be approved in the USA. This agent may lead to earlier initiation of GLP-1RA therapy in the type 2 diabetes continuum of care, and represents a valuable treatment option for patients with a preference for oral therapy. The efficacy and safety of oral semaglutide was assessed in the PIONEER clinical trial program, which included 9543 patients (1293 Japanese). The program included 10 trials, two of which were conducted specifically in Japan. Across the whole program, oral semaglutide was shown to be effective in helping patients achieve glycemic control and reducing body weight. The highest approved dose of oral semaglutide (14 mg) reduced glycated hemoglobin significantly more than placebo, empagliflozin, dulaglutide, and sitagliptin, and was non-inferior to liraglutide. Superior reductions in body weight were also observed with oral semaglutide 14 mg compared with placebo, sitagliptin, and liraglutide, and similar body weight reductions were seen vs. empagliflozin. In all the PIONEER trials, oral semaglutide was well tolerated; there were no unexpected safety concerns and the safety profile was consistent with other GLP-1RAs. Oral semaglutide also demonstrated a favorable cardiovascular safety profile, and significant reductions in cardiovascular death and all-cause mortality vs. placebo in the PIONEER 6 trial. Oral semaglutide, therefore, represents an effective treatment option, that may lead to earlier initiation of GLP-1RA therapy in the diabetes treatment landscape.

Abstract
BACKGROUND Previously, the only available glucagon-like peptide-1 receptor agonists (GLP-1 RA) were injectable. Approval of oral semaglutide (Rybelsus®) represents the first orally available GLP-1 RA. OBJECTIVE To review the literature and describe pharmacologic, pharmacokinetic, and pharmacodynamics properties; clinical safety; and efficacy of oral semaglutide, a newly approved oral GLP-1 RA. METHODS A MEDLINE (1995-October 2019) and ClinicalTrials.gov search was conducted using the terms oral semaglutide, semaglutide, PIONEER, and a combination of those terms. Reference citations from publications identified were also reviewed. All English-language studies, including abstracts, evaluating oral semaglutide use in humans were included in this review. CONCLUSIONS The approval of oral semaglutide (Rybelsus®) represents a paradigm shift in the management of T2D as this is the first FDA-approved oral GLP-1 RA. Oral semaglutide may be an attractive option for patients with T2D who require improved glycemic control, would like to lose weight, and who are not interested in injectable therapy. However, the lack of positive cardiovascular (CV) and renal data are significant limitations to its use.

Abstract
INTRODUCTION The PIONEER trial programme showed that, after 52 weeks, the novel oral glucagon-like peptide-1 (GLP-1) analogue semaglutide 14 mg was associated with significantly greater reductions in glycated haemoglobin (HbA1c) versus a sodium-glucose cotransporter-2 inhibitor (empagliflozin 25 mg), a dipeptidyl peptidase-4 inhibitor (sitagliptin 100 mg) and an injectable GLP-1 analogue (liraglutide 1.8 mg). The aim of the present analysis was to assess the long-term cost-effectiveness of oral semaglutide 14 mg versus each of these comparators in the UK setting. METHODS Analyses were performed from a healthcare payer perspective using the IQVIA CORE Diabetes Model, in which outcomes were projected over patient lifetimes (50 years). Baseline cohort characteristics and treatment effects were based on 52-week data from the PIONEER 2, 3 and 4 randomised controlled trials, comparing oral semaglutide with empagliflozin, sitagliptin and liraglutide, respectively. Treatment switching occurred when HbA1c exceeded 7.5% (58 mmol/mol). Utilities, treatment costs and costs of diabetes-related complications (in pounds sterling [GBP]) were taken from published sources. The acquisition cost of oral semaglutide was assumed to match that of once-weekly semaglutide. RESULTS Oral semaglutide was associated with improvements in quality-adjusted life expectancy of 0.09 quality-adjusted life years (QALYs) versus empagliflozin, 0.20 QALYs versus sitagliptin and 0.07 QALYs versus liraglutide. Direct costs over a patient's lifetime were GBP 971 and GBP 963 higher with oral semaglutide than with empagliflozin and sitagliptin, respectively, but GBP 1551 lower versus liraglutide. Oral semaglutide was associated with a reduced incidence of diabetes-related complications versus all comparators. Therefore, oral semaglutide 14 mg was associated with incremental cost-effectiveness ratios of GBP 11,006 and 4930 per QALY gained versus empagliflozin 25 mg and sitagliptin 100 mg, respectively, and was more effective and less costly (dominant) versus liraglutide 1.8 mg. CONCLUSION Oral semaglutide was cost-effective versus empagliflozin and sitagliptin, and dominant versus liraglutide, for the treatment of type 2 diabetes in the UK.

Abstract
INTRODUCTION Oral semaglutide is the first orally administered glucagon-like peptide-1 receptor agonist for the treatment of type 2 diabetes, and has been evaluated in the PIONEER clinical trial program. These trials assessed the proportions of patients achieving single and composite endpoints, encompassing glycemic control [defined in terms of glycated hemoglobin (HbA1c)], weight loss, and hypoglycemia. The present study assessed the cost of control with oral semaglutide versus empagliflozin, sitagliptin, and liraglutide in the US. METHODS Four endpoints were evaluated: (1) HbA1c ≤ 6.5%; (2) HbA1c < 7.0%; (3) ≥ 1.0%-point HbA1c reduction and weight loss ≥ 3.0%; and (4) HbA1c < 7.0% without hypoglycemia and without weight gain. The proportions of patients achieving each endpoint were sourced from the PIONEER 2, 3 and 4 trials. Treatment costs were accounted over an annual time-period in 2019 US dollars (USD), based on wholesale acquisition cost. Cost of control was calculated by dividing treatment costs by the proportion of patients achieving each target. RESULTS Oral semaglutide was consistently associated with the lowest cost of control for all four endpoints. For the targets of HbA1c ≤ 6.5% and HbA1c < 7.0%, oral semaglutide 14 mg was associated with lower cost of control than empagliflozin 25 mg, sitagliptin 100 mg and liraglutide 1.8 mg by USD 15,036, 14,697, and 6996, respectively, and USD 931, 346 and 4497, respectively. For the double composite endpoint, cost of control was lower with oral semaglutide 14 mg by USD 525, 32,277 and 13,011, respectively versus empagliflozin 25 mg, sitagliptin 100 mg and liraglutide 1.8 mg. For the triple composite endpoint, cost of control was lower with oral semaglutide 14 mg by USD 1255, 7510 and 5774, respectively. CONCLUSION Oral semaglutide was associated with lower cost of bringing patients with type 2 diabetes to four clinically-relevant treatment targets versus empagliflozin, sitagliptin, and liraglutide in the US.
