Summary of the safety profileIn 10 phase 3a trials, 5 707 patients were exposed to semaglutide alone or in combination with otherglucose-lowering medicinal products. The duration of the treatment ranged from 26 weeks to78 weeks. The most frequently reported adverse reactions in clinical trials were gastrointestinaldisorders, including nausea (very common), diarrhoea (very common) and vomiting (common).
Tabulated list of adverse reactionsTable 1 lists adverse reactions identified in phase 3 trials (further described in section 5.1) and post-marketing reports in patients with type 2 diabetes mellitus. The frequencies of the adverse reactions(except diabetic retinopathy complications and dysaesthesia, see footnotes in Table 1) are based on apool of the phase 3a trials excluding the cardiovascular outcomes trial.
The reactions are listed below by system organ class and absolute frequency. Frequencies are definedas: very common: (≥ 1/10); common: (≥ 1/100 to < 1/10); uncommon: (≥ 1/1 000 to < 1/100); rare:(≥ 1/10 000 to < 1/1 000) and very rare: (< 1/10 000); not known (cannot be estimated from theavailable data). Within each frequency grouping, adverse reactions are presented in order ofdecreasing seriousness.

Description of selected adverse reactionsHypoglycaemiaSevere hypoglycaemia was primarily observed when semaglutide was used with a sulfonylurea(< 0.1% of subjects, < 0.001 events/patient year) or insulin (1.1% of subjects, 0.013 events/patientyear). Few episodes (0.1% of subjects, 0.001 events/patient year) were observed with semaglutide incombination with oral antidiabetics other than sulfonylurea.
Gastrointestinal adverse reactionsNausea occurred in 15%, diarrhoea in 10%, and vomiting in 7% of patients when treated withsemaglutide. Most events were mild to moderate in severity and of short duration. The events led totreatment discontinuation in 4% of subjects. The events were most frequently reported during the firstmonths on treatment.
In PIONEER PLUS when treated with semaglutide 25 mg and 50 mg nausea occurred in 27% and27%, diarrhoea in 13% and 14%, and vomiting in 17% and 18% of patients, respectively. These eventsled to treatment discontinuation in 6% and 8% of patients, respectively.
Most events were mild to moderate in severity and of short duration. The events were most frequentlyreported during dose escalation the first months on treatment.
Patients with gastroparesis may experience more serious or severe gastrointestinal effects when treatedwith semaglutide.
Acute pancreatitis confirmed by adjudication has been reported in phase 3a trials, semaglutide(< 0.1%) and comparator (0.2%). In the cardiovascular outcomes trial PIONEER 6 the frequency ofacute pancreatitis confirmed by adjudication was 0.1% for semaglutide and 0.2% for placebo (seesection 4.4.). In phase 3b cardiovascular outcomes trial SOUL, the frequency of acute pancreatitisconfirmed by adjudication was 0.4% for semaglutide and 0.4% for placebo.
Diabetic retinopathy complicationsA 2-year clinical trial with subcutaneous semaglutide investigated 3 297 patients with type 2 diabetes,with high cardiovascular risk, long duration of diabetes and poorly controlled blood glucose. In thistrial, adjudicated events of diabetic retinopathy complications occurred in more patients treated withsubcutaneous semaglutide (3.0%) compared to placebo (1.8%). This was observed in insulin-treatedpatients with known diabetic retinopathy. The treatment difference appeared early and persistedthroughout the trial. Systematic evaluation of diabetic retinopathy complication was only performed inthe cardiovascular outcomes trial with subcutaneous semaglutide. In clinical trials with Rybelsus of upto 18 months duration involving 6 352 patients with type 2 diabetes, adverse events related to diabeticretinopathy were reported in similar proportions in subjects treated with semaglutide (4.2%) andcomparators (3.8%).
Non-arteritic anterior ischaemic optic neuropathy (NAION)
Results from several large epidemiological studies suggest that exposure to semaglutide in adults withtype 2 diabetes is associated with an approximately two-fold increase in the relative risk of developing
NAION, corresponding to approximately one additional case per 10 000 person-years of treatment.
ImmunogenicityConsistent with the potential immunogenic properties of medicinal products containing proteins orpeptides, patients may develop antibodies following treatment with semaglutide. The proportion ofsubjects tested positive for anti-semaglutide antibodies at any time point after baseline was low (0.5%)and no subjects had neutralising anti-semaglutide antibodies or anti-semaglutide antibodies withneutralising effect on endogenous GLP-1 at end-of-trial.
Heart rate increaseIncreased heart rate has been observed with GLP-1 receptor agonists. In the phase 3a trials, meanchanges of 0 to 4 beats per minute (bpm) from a baseline of 69 to 76 were observed in patients treatedwith Rybelsus.
Dysaesthesia
Events related to a clinical picture of altered skin sensation such as paraesthesia, pain of skin, sensitiveskin, dysaesthesia and burning skin sensation were reported in 2.1% and 5.2% of patients treated withoral semaglutide 25 mg and 50 mg, respectively. The events were mild to moderate in severity andmost patients recovered while on continued treatment.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
Pharmacotherapeutic group: Drugs used in diabetes, Glucagon-like peptide-1 (GLP-1) analogues,
ATC code: A10BJ06
Mechanism of actionSemaglutide is a GLP-1 analogue with 94% sequence homology to human GLP-1. Semaglutide acts asa GLP-1 receptor agonist that selectively binds to and activates the GLP-1 receptor, the target fornative GLP-1.
GLP-1 is a physiological hormone that has multiple actions in glucose and appetite regulation, and inthe cardiovascular system. The glucose and appetite effects are specifically mediated via GLP-1receptors in the pancreas and the brain.
Semaglutide reduces blood glucose in a glucose-dependent manner by stimulating insulin secretionand lowering glucagon secretion when blood glucose is high. The mechanism of blood glucoselowering also involves a minor delay in gastric emptying in the early postprandial phase. Duringhypoglycaemia, semaglutide diminishes insulin secretion and does not impair glucagon secretion. Themechanism of semaglutide is independent of the route of administration.
Semaglutide reduces body weight and body fat mass through lowered energy intake, involving anoverall reduced appetite. In addition, semaglutide reduces the preference for high fat foods.
GLP-1 receptors are expressed in the heart, vasculature, immune system and kidneys. Semaglutide hasa beneficial effect on plasma lipids, lowers systolic blood pressure and reduces inflammation inclinical studies. In animal studies, semaglutide attenuates the development of atherosclerosis bypreventing aortic plaque progression and reducing inflammation in the plaque.
The mechanism of action of semaglutide for cardiovascular risk reduction is likely multifactorial, inpart driven by reduction in HbA1c and effects on known cardio-kidney-metabolic risk factors includingreduction in blood pressure, and body weight, improvements in lipid profile, and kidney function, andanti-inflammatory effects as demonstrated by reductions in hsCRP. The exact mechanism ofcardiovascular risk reduction has not been established.
Pharmacodynamic effectsThe pharmacodynamic evaluations described below were performed with orally administeredsemaglutide after 12 weeks of treatment.
Fasting and postprandial glucoseSemaglutide reduces fasting and postprandial glucose concentrations. In patients with type 2 diabetes,treatment with semaglutide resulted in a relative reduction compared to placebo of 22% [13; 30] forfasting glucose and 29% [19; 37] for postprandial glucose.
Glucagon secretionSemaglutide lowers the postprandial glucagon concentrations. In patients with type 2 diabetes,semaglutide resulted in the following relative reductions in glucagon compared to placebo:postprandial glucagon response of 29% [15; 41].
Gastric emptyingSemaglutide causes a minor delay in early postprandial gastric emptying, with paracetamol exposure(AUC0-1h) 31% [13; 46] lower in the first hour after the meal, thereby reducing the rate at whichglucose appears in the circulation postprandially.
Fasting and postprandial lipidsSemaglutide compared to placebo lowered fasting triglyceride and very-low-density lipoproteins(VLDL) cholesterol concentrations by 19% [8; 28] and 20% [5; 33], respectively. The postprandialtriglyceride and VLDL cholesterol response to a high fat meal was reduced by 24% [9; 36] and 21%[7; 32], respectively. ApoB48 was reduced both in fasting and postprandial state by 25% [2; 42] and30% [15; 43], respectively.
Clinical efficacy and safetyThe efficacy and safety of Rybelsus have been evaluated in eight global randomised controlled phase3a trials. Phase 3a studies were conducted with tablets containing 3 mg, 7 mg and 14 mg semaglutidewhich are bioequivalent to 1.5 mg, 4 mg and 9 mg semaglutide, respectively. In seven trials, theprimary objective was the assessment of the glycaemic efficacy; in one trial (PIONEER 6), theprimary objective was the assessment of cardiovascular outcomes.
The trials included 8 842 randomised patients with type 2 diabetes (5 169 treated with semaglutide),including 1 165 patients with moderate renal impairment. Patients had an average age of 61 years(range 18 to 92 years), with 40% of patients ≥ 65 years of age and 8% ≥ 75 years of age. The efficacyof semaglutide was compared with placebo or active controls (sitagliptin, empagliflozin andliraglutide).
The efficacy and safety of semaglutide 25 mg and 50 mg once daily was evaluated in a phase 3b trial(PIONEER PLUS) including 1 606 randomised patients.
A phase 3b cardiovascular outcomes trial (SOUL) including 9 650 patients was conducted todemonstrate that oral semaglutide lowers the risk of major adverse cardiovascular events (MACE)compared to placebo in addition to standard of care, in patients with type 2 diabetes and establishedcardiovascular disease and/or chronic kidney disease.
The efficacy of semaglutide was not impacted by baseline age, gender, race, ethnicity, body weight,
BMI, diabetes duration, upper gastrointestinal disease and level of renal function.

PIONEER PLUS - Efficacy and safety of semaglutide 25 mg and 50 mg compared with semaglutide14 mg once daily in subjects with type 2 diabetes
In a 68-week double-blinded clinical trial 1 606 patients with type 2 diabetes on stable doses of 1-3oral anti-diabetic drugs (metformin, sulfonylureas, SGLT2 inhibitors or DPP-4 inhibitors*) wererandomized to receive maintenance doses of either semaglutide 14 mg, semaglutide 25 mg orsemaglutide 50 mg once daily.
*DPP-4 inhibitors were to be discontinued at randomisation.
Treatment with semaglutide 25 mg and 50 mg once daily was superior in reducing HbA1c and bodyweight compared to semaglutide 14 mg (see Table 9). Week 68 data support a sustained effect of oralsemaglutide 14 mg, 25 mg and 50 mg on HbA1c and body weight (see Figure 1).

Cardiovascular outcomes
SOUL: Cardiovascular outcomes trial in patients with type 2 diabetes
In a double-blind, placebo-controlled, event driven trial, 9 650 patients, 50 years of age or older withtype 2 diabetes at high cardiovascular risk, defined as having established cardiovascular disease and/orchronic kidney disease, were randomised to either semaglutide 14 mg (bioequivalent to semaglutide9 mg) once-daily or placebo once daily added to standard of care.
In total, 5 468 patients (56.7%) had established cardiovascular disease without chronic kidney disease,1 241 (12.9%) had chronic kidney disease only and 2 620 (27.2%) had both cardiovascular disease andkidney disease. The mean age at baseline was 66.1 years, and 71.1% of the patients were men. Themean duration of diabetes was 15.4 years, the mean HbA1c was 8.0%, the mean BMI was 31.1 kg/m2,and the mean eGFR was 73.8 mL/min/1.73 m2. Medical history included stroke (15.4%), myocardialinfarction (40.0%), and peripheral artery disease (15.7%). At baseline, 26.9% of the patients weretreated with sodium-glucose cotransporter2 (SGLT2) inhibitors.
The primary endpoint was time from randomisation to first occurrence of a major adversecardiovascular event (MACE): cardiovascular death, non-fatal myocardial infarction, or non-fatalstroke. The primary endpoint, time to first MACE, occurred in 1 247 of the 9 650 included patients,579 first MACE (12.0%) were recorded among the 4 825 patients treated with semaglutide, comparedto 668 first MACE (13.8%) among the 4 825 patients treated with placebo.
Superiority of semaglutide versus placebo for MACE was confirmed with a hazard ratio of 0.86[0.77; 0.96] [95% CI], corresponding to a relative risk reduction in MACE of 14% (see Figure 2). Thereduction of MACE with semaglutide was consistent across subgroups of age, sex, race, ethnicity,
BMI at baseline, or level of kidney function impairment.
Analysis of the first composite kidney event (the first confirmatory secondary endpoint) resulted in ahazard ratio of 0.91 [0.80; 1.05] [95% CI].

PIONEER 6: Cardiovascular outcomes trial in patients with type 2 diabetes
In a double-blind trial (PIONEER 6), 3 183 patients, 50 years of age or older with type 2 diabetes athigh cardiovascular risk were randomised to semaglutide 14 mg (bioequivalent to semaglutide 9 mg)once daily or placebo in addition to standard-of-care. The median observation period was 16 months.
PIONEER 6 was a pre−approval CVOT designed to establish CV safety.
The primary endpoint was time from randomisation to first occurrence of a major adversecardiovascular event (MACE): cardiovascular death, non-fatal myocardial infarction or non-fatalstroke.
The total number of first MACE was 137: 61 (3.8%) with semaglutide and 76 (4.8%) with placebo.
The analysis of time to first MACE resulted in a HR of 0.79 [0.57; 1.11]95% CI.
Body weightBy end-of-treatment, 27-65.7% of the patients had achieved a weight loss of ≥ 5% and 6-34.7% hadachieved a weight loss of ≥ 10% with semaglutide, compared with 12-39% and 2-8%, respectively,with the active comparators.
In the cardiovascular outcomes trial SOUL, a reduction in body weight from baseline to week 104 wasobserved with semaglutide vs. placebo, in addition to standard-of-care (‑4.22 kg vs. ‑1.27 kg).
Blood pressureTreatment with semaglutide had reduced systolic blood pressure by 2-7 mmHg.
Paediatric populationThe European Medicines Agency has deferred the obligation to submit the results of studies with
Rybelsus in one or more subsets of the paediatric population in type 2 diabetes (see section 4.2 forinformation on paediatric use).
