WARNING
RISK OF THYROID C-CELL TUMORS
RYBELSUS tablets, for oral use, contain semaglutide, a GLP-1 receptor agonist. The peptide backbone is produced by yeast fermentation. The main protraction mechanism of semaglutide is albumin binding, facilitated by modification of position 26 lysine with a hydrophilic spacer and a C18 fatty di-acid. Furthermore, semaglutide is modified in position 8 to provide stabilization against degradation by the enzyme dipeptidyl-peptidase 4 (DPP-4). A minor modification was made in position 34 to ensure the attachment of only one fatty di-acid. The molecular formula is C187H291N45O59 and the molecular weight is 4113.58 g/mol.

The following serious adverse reactions are described below or elsewhere in the prescribing information:
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of RYBELSUS (formulation R2 – 1.5 mg, 4 mg, and 9 mg strengths) [see DOSAGE AND ADMINISTRATION] and RYBELSUS (formulation R1 – 3 mg, 7, mg, and 14 mg strengths) [see DOSAGE AND ADMINISTRATION] has been established as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus based on adequate and well-controlled studies of RYBELSUS (formulation R1) in adult patients with type 2 diabetes mellitus [see CLINICAL PHARMACOLOGY and Clinical Studies]. Below is a display of the safety results of the adequate and well-controlled studies of RYBELSUS (formulation R1) in adult patients with type 2 diabetes mellitus.
The data in Table 1 are derived from 2 placebo-controlled trials in adult patients with type 2 diabetes mellitus [see Clinical Studies]. These data reflect exposure of 1071 patients to RYBELSUS with a mean duration of exposure of 41.8 weeks. The mean age of patients was 58 years, 3.9% were 75 years or older and 52% were male. In these trials, 63% were White, 6% were Black or African American, and 27% were Asian; 19% identified as Hispanic or Latino ethnicity. At baseline, patients had type 2 mellitus diabetes for an average of 9.4 years and had a mean HbA1c of 8.1%. At baseline, 20.1% of the population reported retinopathy. Baseline estimated renal function was normal (eGFR ≥90 mL/min/1.73m2) in 66.2%, mildly impaired (eGFR 60 to 90 mL/min/1.73m2) in 32.4% and moderately impaired (eGFR 30 to 60 mL/min/1.73m2) in 1.4% of patients.
The occurrence of adverse reactions was also evaluated in a larger pool of adult patients with type 2 diabetes mellitus participating in 9 placebo- and active-controlled trials [see Clinical Studies]. In this pool, 4,116 patients with type 2 diabetes mellitus were treated with RYBELSUS for a mean duration of 59.8 weeks. The mean age of patients was 58 years, 5% were 75 years or older and 55% were male. In these trials, 65% were White, 6% were Black or African American, and 24% were Asian; 15% identified as Hispanic or Latino ethnicity. At baseline, patients had type 2 diabetes mellitus for an average of 8.8 years and had a mean HbA1c of 8.2%. At baseline, 16.6% of the population reported retinopathy. Baseline estimated renal function was normal (eGFR ≥90 mL/min/1.73m2) in 65.9%, mildly impaired (eGFR 60 to 90 mL/min/1.73m2) in 28.5%, and moderately impaired (eGFR 30 to 60 mL/min/1.73m2) in 5.4% of the patients.
Table 2 shows common adverse reactions, excluding hypoglycemia, associated with the use of RYBELSUS in adult patients with type 2 diabetes mellitus in the pool of placebo-controlled trials. These adverse reactions occurred more commonly on RYBELSUS than on placebo and occurred in at least 5% of patients treated with RYBELSUS.
Table 2. Adverse Reactions in Placebo-Controlled Trials Reported in ≥5% of RYBELSUS-Treated Patients with Type 2 Diabetes Mellitus
| Adverse Reaction | Placebo (N=362) % |
RYBELSUS 7 mg (N=356) % |
RYBELSUS 14 mg (N=356) % |
| Nausea | 6 | 11 | 20 |
| Abdominal Pain | 4 | 10 | 11 |
| Diarrhea | 4 | 9 | 10 |
| Decreased appetite | 1 | 6 | 9 |
| Vomiting | 3 | 6 | 8 |
| Constipation | 2 | 6 | 5 |
In the pool of placebo- and active-controlled trials, the types and frequency of common adverse reactions, excluding hypoglycemia, were similar to those listed in Table 1.
In the pool of placebo-controlled trials, gastrointestinal adverse reactions occurred more frequently among patients who received RYBELSUS than placebo: RYBELSUS 14 mg once daily (41%), RYBELSUS 7 mg once daily (32%), and placebo (21%), including severe reactions (RYBELSUS 14 mg 2.0%, RYBELSUS 7 mg 0.6%, placebo 0.3%). The majority of reports of nausea, vomiting, and/or diarrhea occurred during dose escalation. A greater percentage of patients who received RYBELSUS 14 mg once daily (8%) and RYBELSUS 7 mg once daily (4%) discontinued treatment due to gastrointestinal adverse reactions than patients who received placebo (1%).
In addition to the reactions in Table 1, the following gastrointestinal adverse reactions with a frequency of <5% occurred in RYBELSUS-treated patients (frequencies listed, respectively, as 14 mg once daily, 7 mg once daily, and placebo): abdominal distension (3%, 2%, and 1%), dyspepsia (0.6%, 3%, 0.6%), eructation (2%, 0.6%, 0%,), flatulence (1%, 2%, 0%), gastroesophageal reflux disease (2%, 2%, 0.3%), and gastritis (2%, 2%, 0.8%).
In the pool of placebo- and active-controlled trials with RYBELSUS, pancreatitis was reported as a serious adverse event in 6 RYBELSUS-treated patients (0.1 events per 100 patient years) versus 1 in comparator-treated patients (<0.1 events per 100 patient years).
In the pool of placebo-and active-controlled trials with RYBELSUS, patients reported diabetic retinopathy related adverse reactions during the trial (4.2% with RYBELSUS and 3.8% with comparator).
Table 3 summarizes the incidence of hypoglycemia by various definitions in the placebo-controlled trials.

Hypoglycemia was more frequent when RYBELSUS was used in combination with insulin secretagogues (e.g., sulfonylureas) or insulin.
In placebo-controlled trials, patients exposed to RYBELSUS 7 mg and 14 mg had a mean increase from baseline in amylase of 10% and 13%, respectively, and lipase of 30% and 34%, respectively. These changes were not observed in placebo-treated patients.
In placebo-controlled trials, cholelithiasis was reported in 1% of patients treated with RYBELSUS 7 mg. Cholelithiasis was not reported in RYBELSUS 14 mg or placebo-treated patients.
In placebo-controlled trials, RYBELSUS 7 mg and 14 mg resulted in a mean increase in heart rate of 1 to 3 beats per minute. There was no change in heart rate in placebo-treated patients.
The following adverse reactions have been reported during post-approval use of semaglutide, the active ingredient of RYBELSUS. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
RYBELSUS stimulates insulin release in the presence of elevated blood glucose concentrations. Patients receiving RYBELSUS in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.
When initiating RYBELSUS, consider reducing the dose of concomitantly administered insulin secretagogue (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia [see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS].
RYBELSUS causes a delay of gastric emptying, and thereby has the potential to impact the absorption of other oral drugs. Levothyroxine exposure was increased 33% (90% CI: 125-142) when administered with RYBELSUS in a drug interaction study [see CLINICAL PHARMACOLOGY].
When co-administering RYBELSUS with other oral drugs that have a narrow therapeutic index or that require clinical monitoring, consider increased clinical or laboratory monitoring [see DOSAGE AND ADMINISTRATION].
Included as part of the "PRECAUTIONS" Section
In mice and rats, semaglutide caused a dose-dependent and treatment-duration-dependent increase in the incidence of thyroid C-cell tumors (adenomas and carcinomas) after lifetime exposure at clinically relevant plasma exposures [see Nonclinical Toxicology]. It is unknown whether RYBELSUS causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of semaglutide-induced rodent thyroid C-cell tumors has not been determined.
Cases of MTC in patients treated with liraglutide, another GLP-1 receptor agonist, have been reported in the postmarketing period; the data in these reports are insufficient to establish or exclude a causal relationship between MTC and GLP-1 receptor agonist use in humans.
RYBELSUS is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2. Counsel patients regarding the potential risk for MTC with the use of RYBELSUS and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness).
Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with RYBELSUS. Such monitoring may increase the risk of unnecessary procedures, due to the low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin value may indicate MTC and patients with MTC usually have calcitonin values >50 ng/L. If serum calcitonin is measured and found to be elevated, the patient should be further evaluated. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated.
Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists, including RYBELSUS [see ADVERSE REACTIONS]. After initiation of RYBELSUS, observe patients carefully for signs and symptoms of pancreatitis (including persistent severe abdominal pain, sometimes radiating to the back and which may or may not be accompanied by vomiting). If pancreatitis is suspected, discontinue RYBELSUS and initiate appropriate management.
In a pooled analysis of glycemic control trials with RYBELSUS, patients reported diabetic retinopathy related adverse reactions during the trial (4.2% with RYBELSUS and 3.8% with comparator) [see ADVERSE REACTIONS].
In a 2-year cardiovascular outcomes trial with semaglutide injection involving patients with type 2 diabetes mellitus and high cardiovascular risk, diabetic retinopathy complications (which was a 4-component adjudicated endpoint) occurred in patients treated with semaglutide injection (3%) compared to placebo (1.8%). The absolute risk increase for diabetic retinopathy complications was larger among patients with a history of diabetic retinopathy at baseline (semaglutide injection 8.2%, placebo 5.2%) than among patients without a known history of diabetic retinopathy (semaglutide injection 0.7%, placebo 0.4%).
Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. The effect of long-term glycemic control with semaglutide on diabetic retinopathy complications has not been studied. Patients with a history of diabetic retinopathy should be monitored for progression of diabetic retinopathy.
Patients receiving RYBELSUS in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia [see ADVERSE REACTIONS and DRUG INTERACTIONS].
The risk of hypoglycemia may be lowered by a reduction in the dosage of sulfonylurea (or other concomitantly administered insulin secretagogue) or insulin. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.
There have been postmarketing reports of acute kidney injury and worsening of chronic renal failure, which may sometimes require hemodialysis, in patients treated with GLP-1 receptor agonists, including semaglutide. Some of these events have been reported in patients without known underlying renal disease. A majority of the reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration.
Monitor renal function when initiating or escalating doses of RYBELSUS in patients reporting severe adverse gastrointestinal reactions.
Use of RYBELSUS has been associated with gastrointestinal adverse reactions, sometimes severe [see ADVERSE REACTIONS]. In RYBELSUS clinical trials, severe gastrointestinal adverse reactions were reported more frequently among patients receiving RYBELSUS (7 mg 0.6%, 14 mg 2%) than placebo (0.3%).
RYBELSUS is not recommended in patients with severe gastroparesis.
Serious hypersensitivity reactions (e.g., anaphylaxis, angioedema) have been reported in patients treated with RYBELSUS. If hypersensitivity reactions occur, discontinue use of RYBELSUS; treat promptly per standard of care, and monitor until signs and symptoms resolve. RYBELSUS is contraindicated in patients with a prior serious hypersensitivity reaction to semaglutide or to any of the excipients in RYBELSUS [see ADVERSE REACTIONS].
Anaphylaxis and angioedema have been reported with GLP-1 receptor agonists. Use caution in a patient with a history of angioedema or anaphylaxis with another GLP-1 receptor agonist because it is unknown whether such patients will be predisposed to anaphylaxis with RYBELSUS.
Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. In placebo-controlled trials, cholelithiasis was reported in 1% of patients treated with RYBELSUS 7 mg. Cholelithiasis was not reported in RYBELSUS 14 mg or placebo-treated patients [see ADVERSE REACTIONS]. If cholelithiasis or cholecystitis is suspected, gallbladder studies and appropriate clinical follow-up are indicated [see ADVERSE REACTIONS].
RYBELSUS delays gastric emptying [see CLINICAL PHARMACOLOGY]. There have been rare postmarketing reports of pulmonary aspiration in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation who had residual gastric contents despite reported adherence to preoperative fasting recommendations.
Available data are insufficient to inform recommendations to mitigate the risk of pulmonary aspiration during general anesthesia or deep sedation in patients taking RYBELSUS, including whether modifying preoperative fasting recommendations or temporarily discontinuing RYBELSUS could reduce the incidence of retained gastric contents. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking RYBELSUS.
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Inform patients that semaglutide causes thyroid C-cell tumors in rodents and that the human relevance of this finding has not been determined. Counsel patients to report symptoms of thyroid tumors (e.g., a lump in the neck, hoarseness, dysphagia, or dyspnea) to their physician [see BOX WARNING and WARNINGS AND PRECAUTIONS].
Inform patients of the potential risk for acute pancreatitis and its symptoms: severe abdominal pain that may radiate to the back, and which may or may not be accompanied by vomiting. Instruct patients to discontinue RYBELSUS promptly and contact their physician if pancreatitis is suspected [see WARNINGS AND PRECAUTIONS].
Inform patients to contact their physician if changes in vision are experienced during treatment with RYBELSUS [see WARNINGS AND PRECAUTIONS].
Inform patients that the risk of hypoglycemia is increased when RYBELSUS is used with an insulin secretagogue (such as a sulfonylurea) or insulin. Educate patients on the signs and symptoms of hypoglycemia [see WARNINGS AND PRECAUTIONS].
Advise patients treated with RYBELSUS of the potential risk of dehydration due to gastrointestinal adverse reactions and take precautions to avoid fluid depletion. Inform patients of the potential risk for worsening renal function and explain the associated signs and symptoms of renal impairment, as well as the possibility of dialysis as a medical intervention if renal failure occurs [see WARNINGS AND PRECAUTIONS].
Inform patients of the potential risk of severe gastrointestinal adverse reactions. Instruct patients to contact their healthcare provider if they have severe or persistent gastrointestinal symptoms [see WARNINGS AND PRECAUTIONS].
Inform patients that serious hypersensitivity reactions have been reported during postmarketing use of RYBELSUS. Advise patients on the symptoms of hypersensitivity reactions and instruct them to stop taking RYBELSUS and seek medical advice promptly if such symptoms occur [see WARNINGS AND PRECAUTIONS].
Inform patients of the potential risk for cholelithiasis or cholecystitis. Instruct patients to contact their physician if cholelithiasis or cholecystitis is suspected for appropriate clinical follow-up [see WARNINGS AND PRECAUTIONS].
Inform patients that RYBELSUS may cause their stomach to empty more slowly which may lead to complications with anesthesia or deep sedation during planned surgeries or procedures. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking RYBELSUS [see WARNINGS AND PRECAUTIONS].
Advise a pregnant woman of the potential risk to a fetus. Advise women to inform their healthcare provider if they are pregnant or intend to become pregnant [see Use In Specific Populations].
RYBELSUS passes into breast milk, and it is not known how it affects your baby. Advise females not to breastfeed during treatment with RYBELSUS [see Use In Specific Populations].
Discontinue RYBELSUS at least 2 months before a planned pregnancy due to the long washout period for semaglutide [see Use In Specific Populations ].
In a 2-year carcinogenicity study in CD-1 mice, subcutaneous doses of 0.3, 1 and 3 mg/kg/day [9-, 33- and 113fold the maximum recommended human dose (MRHD) of RYBELSUS 14 mg, based on AUC] were administered to the males, and 0.1, 0.3 and 1 mg/kg/day (3-, 9-, and 33-fold MRHD) were administered to the females. A statistically significant increase in thyroid C-cell adenomas and a numerical increase in C-cell carcinomas were observed in males and females at all dose levels (>3X human exposure).
In a 2-year carcinogenicity study in Sprague Dawley rats, subcutaneous doses of 0.0025, 0.01, 0.025 and 0.1 mg/kg/day were administered (below quantification, 0.8-, 1.8- and 11-fold the exposure at the MRHD). A statistically significant increase in thyroid C-cell adenomas was observed in males and females at all dose levels, and a statistically significant increase in thyroid C-cell carcinomas was observed in males at ≥0.01 mg/kg/day, at clinically relevant exposures.
Human relevance of thyroid C-cell tumors in rats is unknown and could not be determined by clinical studies or nonclinical studies [see BOX WARNING and WARNINGS AND PRECAUTIONS].
Semaglutide was not mutagenic or clastogenic in a standard battery of genotoxicity tests (bacterial mutagenicity (Ames), human lymphocyte chromosome aberration, rat bone marrow micronucleus).
In a combined fertility and embryo-fetal development study in rats, subcutaneous doses of 0.01, 0.03 and 0.09 mg/kg/day (0.2-, 0.7- and 2.1-fold the MRHD) were administered to male and female rats. Males were dosed for 4 weeks prior to mating, and females were dosed for 2 weeks prior to mating and throughout organogenesis until Gestation Day 17. No effects were observed on male fertility. In females, an increase in estrus cycle length was observed at all dose levels, together with a small reduction in numbers of corpora lutea at ≥0.03 mg/kg/day. These effects were likely an adaptive response secondary to the pharmacological effect of semaglutide on food consumption and body weight.
Available data with RYBELSUS use in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. There are clinical considerations regarding the risks of poorly controlled diabetes in pregnancy (see Clinical Considerations). Based on animal reproduction studies, there may be potential risks to the fetus from exposure to RYBELSUS during pregnancy. RYBELSUS should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
In pregnant rats administered semaglutide during organogenesis, embryofetal mortality, structural abnormalities and alterations to growth occurred at maternal exposures below the maximum recommended human dose (MRHD) based on AUC. In rabbits and cynomolgus monkeys administered semaglutide during organogenesis, early pregnancy losses and structural abnormalities were observed at exposure below the MRHD (rabbit) and ≥10-fold the MRHD (monkey). These findings coincided with a marked maternal body weight loss in both animal species (see Data).
The estimated background risk of major birth defects is 6–10% in women with pre-gestational diabetes with an HbA1c >7 and has been reported to be as high as 20–25% in women with a HbA1c >10. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Disease Associated Maternal and Fetal Risk
Poorly controlled diabetes during pregnancy increases the maternal risk for diabetic ketoacidosis, pre- eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity.
Animal Data
In a combined fertility and embryofetal development study in rats, subcutaneous doses of 0.01, 0.03 and 0.09 mg/kg/day (0.2-, 0.7-, and 2.1-fold the MRHD) were administered to males for 4 weeks prior to and throughout mating and to females for 2 weeks prior to mating, and throughout organogenesis to Gestation Day 17. In parental animals, pharmacologically mediated reductions in body weight gain and food consumption were observed at all dose levels. In the offspring, reduced growth and fetuses with visceral (heart blood vessels) and skeletal (cranial bones, vertebra, ribs) abnormalities were observed at the human exposure.
In an embryofetal development study in pregnant rabbits, subcutaneous doses of 0.0010, 0.0025 or 0.0075 mg/kg/day (0.06-, 0.6-, and 4.4-fold the MRHD) were administered throughout organogenesis from Gestation Day 6 to 19. Pharmacologically mediated reductions in maternal body weight gain and food consumption were observed at all dose levels. Early pregnancy losses and increased incidences of minor visceral (kidney, liver) and skeletal (sternebra) fetal abnormalities were observed at ≥0.0025 mg/kg/day, at clinically relevant exposures.
In an embryofetal development study in pregnant cynomolgus monkeys, subcutaneous doses of 0.015, 0.075, and 0.15 mg/kg twice weekly (1.9-, 9.9-, and 29-fold the MRHD) were administered throughout organogenesis, from Gestation Day 16 to 50. Pharmacologically mediated, marked initial maternal body weight loss and reductions in body weight gain and food consumption coincided with the occurrence of sporadic abnormalities (vertebra, sternebra, ribs) at ≥0.075 mg/kg twice weekly (≥9X human exposure).
In a pre- and postnatal development study in pregnant cynomolgus monkeys, subcutaneous doses of 0.015, 0.075, and 0.15 mg/kg twice weekly (1.3-, 6.4-, and 14-fold the MRHD) were administered from Gestation Day 16 to 140. Pharmacologically mediated marked initial maternal body weight loss and reductions in body weight gain and food consumption coincided with an increase in early pregnancy losses and led to delivery of slightly smaller offspring at ≥0.075 mg/kg twice weekly (≥6X human exposure).
Salcaprozate sodium (SNAC), an absorption enhancer in RYBELSUS, crosses the placenta and reaches fetal tissues in rats. In a pre- and postnatal development study in pregnant Sprague Dawley rats, SNAC was administered orally at 1,000 mg/kg/day (exposure levels were not measured) on Gestation Day 7 through lactation day 20. An increase in gestation length, an increase in the number of stillbirths and a decrease in pup viability were observed.
A clinical lactation study reported semaglutide concentrations below the lower limit of quantification in human breast milk. However, salcaprozate sodium (SNAC) and/or its metabolites are present in human milk. Since the activity of enzymes involved in SNAC clearance may be lower in infants compared to adults, higher SNAC plasma levels may occur in neonates and infants. Because of the unknown potential for serious adverse reactions in the breastfed infant due to the possible accumulation of SNAC, and because there are alternative formulations of semaglutide that do not contain SNAC that can be used during lactation, advise patients that breastfeeding is not recommended during treatment with RYBELSUS.
Discontinue RYBELSUS in women at least 2 months before a planned pregnancy due to the long washout period for semaglutide [see Pregnancy].
The safety and effectiveness of RYBELSUS have not been established in pediatric patients.
In the pool of glycemic control trials, 1,229 (30%) RYBELSUS-treated patients were 65 years of age and over and 199 (5%) RYBELSUS-treated patients were 75 years of age and over [see Clinical Studies]. In PIONEER 6, the cardiovascular outcomes trial, 891 (56%) RYBELSUS-treated patients were 65 years of age and over and 200 (13%) RYBELSUS-treated patients were 75 years of age and over.
No overall differences in safety or effectiveness for RYBELSUS have been observed between patients 65 years of age and older and younger adult patients.
The recommended dosage of RYBELSUS in patients with renal impairment is the same as those with normal renal function.
The safety and effectiveness of RYBELSUS was evaluated in a 26-week clinical study that included 324 patients with moderate renal impairment (eGFR 30 to 59 mL/min/1.73 m2) [see Clinical Studies]. In patients with renal impairment including end-stage renal disease (ESRD), no clinically relevant change in semaglutide pharmacokinetics was observed [see CLINICAL PHARMACOLOGY].
The recommended dosage in patients with hepatic impairment is the same as those with normal hepatic function.
In a study in subjects with different degrees of hepatic impairment, no clinically relevant change in semaglutide pharmacokinetics was observed [see CLINICAL PHARMACOLOGY].
In the event of overdose, appropriate supportive treatment should be initiated according to the patient’s clinical signs and symptoms. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. A prolonged period of observation and treatment for these symptoms may be necessary, taking into account the long half-life of RYBELSUS of approximately 1 week.
RYBELSUS is contraindicated in patients with:
Semaglutide is a GLP-1 analogue with 94% sequence homology to human GLP-1. Semaglutide acts as a GLP-1 receptor agonist that selectively binds to and activates the GLP-1 receptor, the target for native GLP-1.
GLP-1 is a physiological hormone that has multiple actions on glucose, mediated by the GLP-1 receptors.
The principal mechanism of protraction resulting in the long half-life of semaglutide is albumin binding, which results in decreased renal clearance and protection from metabolic degradation. Furthermore, semaglutide is stabilized against degradation by the DPP-4 enzyme.
Semaglutide reduces blood glucose through a mechanism where it stimulates insulin secretion and lowers glucagon secretion, both in a glucose-dependent manner. Thus, when blood glucose is high, insulin secretion is stimulated and glucagon secretion is inhibited. The mechanism of blood glucose lowering also involves a minor delay in gastric emptying in the early postprandial phase.
The pharmacodynamic evaluations described below were in patients with type 2 diabetes mellitus who received once weekly subcutaneous injections of placebo or semaglutide injection over 12 weeks (semaglutide injection-treated patients were started on lower dosages and then titrated up to 1 mg once weekly). RYBELSUS is not approved for subcutaneous use.
Glucose Semaglutide reduces fasting and postprandial glucose concentrations. In patients with type 2 diabetes mellitus, treatment with semaglutide injection 1 mg resulted in reductions in glucose in terms of absolute change from baseline and relative reduction compared to placebo of 29 mg/dL (22%) for fasting glucose, 74 mg/dL (36%) for 2 hour postprandial glucose, and 30 mg/dL (22%) for mean 24 hour glucose concentration.
Both first-and second-phase insulin secretion are increased in patients with type 2 diabetes mellitus treated with semaglutide compared with placebo.
Semaglutide lowers the fasting and postprandial glucagon concentrations.
Semaglutide lowers high blood glucose concentrations by stimulating insulin secretion and lowering glucagon secretion in a glucose-dependent manner.
During induced hypoglycemia, semaglutide did not alter the counter regulatory responses of increased glucagon compared to placebo and did not impair the decrease of C-peptide in patients with type 2 diabetes mellitus.
Semaglutide causes a delay of early postprandial gastric emptying, thereby reducing the rate at which glucose appears in the circulation postprandially.
The effect of subcutaneously administered semaglutide on cardiac repolarization was tested in a thorough QTc trial. At an average exposure level 4-fold higher than that of the maximum recommended dose of RYBELSUS, semaglutide does not prolong QTc intervals to any clinically relevant extent.
Semaglutide estimated mean steady-state concentration was 6.7 nmol/L and 14.6 nmol/L following once daily oral administration of 7 mg and 14 mg of RYBELSUS (formulation R1), respectively, in patients with type 2 diabetes mellitus.
Semaglutide exposures increased in a dose-proportional manner. Steady-state exposure was achieved following 45 weeks of RYBELSUS oral administration.
Semaglutide is co-formulated with salcaprozate sodium which facilitates the absorption of semaglutide after oral RYBELSUS administration. The absorption of semaglutide predominantly occurs in the stomach.
Semaglutide estimated absolute bioavailability was approximately:
Semaglutide maximum concentration was reached approximately 1-hour after oral RYBELSUS administration.
Effect of RYBELSUS Formulation
There were no clinically significant differences observed in the mean steady state AUC0-24h,SS and Cmax,SS between the 3 mg, 7 mg, and 14 mg doses of RYBELSUS (formulation R1) and the 1.5 mg, 4 mg, and 9 mg doses of RYBELSUS (formulation R2), respectively, in a clinical study conducted in healthy subjects.
Effect of Volume and Timing of Water Consumption
Single 10 mg doses of oral semaglutide (formulation R1) were administered with 50 mL or 240 mL of water after an 8-hour overnight fast and a continued fast of 4 hours post-dose in healthy subjects. Semaglutide absorption (i.e., area under the curve (AUC) and peak concentrations (Cmax)) were higher following dosing with 50 mL water compared to that of 240 mL water.
For 10 days, healthy subjects received 10 mg of oral semaglutide (formulation R1) once daily doses with 50 mL or 120 mL of water under fasting conditions with post-dose fasting period of 15, 30, 60, or 120 minutes. In this study, semaglutide absorption (i.e., AUC and Cmax) was higher after a longer post-dose fasting period.There were no clinically significant differences in semaglutide absorption with administration of 50 mL or 120 mL of water.
Semaglutide absolute volume of distribution is approximately 8 L in patients with type 2 diabetes. Semaglutide is > 99% bound to plasma albumin.
Semaglutide elimination half-life is approximately one week with an absolute clearance of approximately 0.04 L/hour in patients with type 2 diabetes. Semaglutide is present in the circulation for about five weeks after the last RYBELSUS dose.
Metabolism
The primary route of elimination for semaglutide is metabolism following proteolytic cleavage of the peptide backbone and sequential beta-oxidation of the fatty acid side chain.
Excretion
The primary excretion routes of semaglutide-related material are via the urine and feces. Approximately 3% of the absorbed dose is excreted in the urine as intact semaglutide.
No clinically significant differences in semaglutide pharmacokinetics were observed based on age (≥ 18 years old), sex, race (White, Asian, or Black or African American), ethnicity, body weight (40-188 kg), upper GI disease (i.e. chronic gastritis and/or gastroesophageal reflux disease), hepatic impairment (i.e., mild, moderate, severe based on the Child-Pugh system), and renal impairment (i.e., mild, moderate, severe, end staged renal disease).
The delay of gastric emptying with semaglutide may influence the absorption of concomitantly administered oral drugs. Trials were conducted to study the potential effect of semaglutide on the absorption of oral drugs taken with semaglutide administered orally at steady-state exposure.
Levothyroxine
Total thyroxine (i.e., adjusted for endogenous levels) AUC of was increased by 33% following administration of a single dose of levothyroxine 600 mcg concomitantly administered with oral semaglutide. Maximum exposure (Cmax) was unchanged.
Other Drugs
No clinically significant differences in semaglutide pharmacokinetics were observed when used concomitantly with omeprazole. No clinically significant differences in the pharmacokinetics of the following drugs were observed when used concomitantly with semaglutide: lisinopril, S-warfarin, R-warfarin, metformin, digoxin, ethinyl estradiol, levonorgestrel, furosemide, or rosuvastatin.
Semaglutide has very low potential to inhibit or induce CYP enzymes, and to inhibit drug transporters.
The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of semaglutide or of other semaglutide products.
During the 26-78 week treatment periods in 5 clinical trials in adults with type 2 diabetes mellitus [see Clinical Studies] and 1 clinical trial in Japanese adults with type 2 diabetes mellitus, 14/2924 (0.5%) of RYBELSUS-treated patients developed anti-semaglutide antibodies. Of these 14 RYBELSUS-treated patients, 7 patients (0.2% of the total RYBELSUS-treated study population) developed antibodies that cross-reacted with native GLP-1. No identified clinically significant effect of anti-semaglutide antibodies on pharmacokinetics of RYBELSUS was observed. There is insufficient information to characterize the effects of anti-semaglutide antibodies on pharmacodynamics, safety, or effectiveness of semaglutide.
Increase in lactate levels and decrease in glucose levels in the plasma and cerebrospinal fluid (CSF) were observed in mechanistic studies with SNAC in rats. Small but statistically significant increases in lactate levels (up to 2fold) were observed in a few animals at approximately the clinical exposure. At higher exposures these findings were associated with moderate to marked adverse clinical signs (lethargy, abnormal respiration, ataxia, and reduced activity, body tone and reflexes) and marked decreases in plasma and CSF glucose levels. These findings are consistent with inhibition of cellular respiration and lead to mortality at SNAC concentrations ≥100-times the clinical Cmax.
RYBELSUS has been studied as monotherapy and in combination with metformin, sulfonylureas, sodium-glucose co-transporter-2 (SGLT-2) inhibitors, insulins, and thiazolidinediones in patients with type 2 diabetes mellius. The efficacy of RYBELSUS was compared with placebo, empagliflozin, sitagliptin, and liraglutide. RYBELSUS has also been studied in patients with type 2 diabetes mellitus with mild and moderate renal impairment.
In patients with type 2 diabetes mellitus, RYBELSUS produced clinically significant reduction from baseline in HbA1c compared with placebo.
The effectiveness of RYBELSUS (formulation R2 – 1.5 mg, 4 mg, and 9 mg strengths) [see DOSAGE AND ADMINISTRATION] and RYBELSUS (formulation R1 – 3 mg, 7, mg, and 14 mg strengths) [see DOSAGE AND ADMINISTRATION] has been established as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus based on adequate and well-controlled studies of RYBELSUS (formulation R1) in adult patients with type 2 diabetes mellitus [see CLINICAL PHARMACOLOGY]. Below is a display of the efficacy results of the adequate and well-controlled studies of RYBELSUS (formulation R1) in adult patients with type 2 diabetes mellitus.
The efficacy of RYBELSUS was not impacted by baseline age, sex, race, ethnicity, BMI, body weight, duration of diabetes, and degree of renal impairment.
In a 26-week double-blind trial (NCT02906930), 703 adult patients with type 2 diabetes mellitus inadequately controlled with diet and exercise were randomized to RYBELSUS 3 mg, RYBELSUS 7 mg or RYBELSUS 14 mg once daily or placebo. Patients had a mean age of 55 years and 51% were men. The mean duration of type 2 diabetes mellitus was 3.5 years, and the mean BMI was 32 kg/m2. Overall, 75% were White, 5% were Black or African American, and 17% were Asian; 26% identified as Hispanic or Latino ethnicity.
Monotherapy with RYBELSUS 7 mg and RYBELSUS 14 mg once daily for 26 weeks resulted in a statistically significant reduction in HbA1c compared with placebo (see Table 4).

PIONEER 6 (NCT02692716) was a multi-center, multi-national, placebo-controlled, double-blind trial. In this trial, 3,183 adult patients with inadequately controlled type 2 diabetes mellitus and atherosclerotic cardiovascular disease were randomized to RYBELSUS 14 mg once daily or placebo for a median observation time of 16 months. The trial compared the risk of a Major Adverse Cardiovascular Event (MACE) between RYBELSUS 14 mg and placebo when these were added to and used concomitantly with standard of care treatments for diabetes and cardiovascular disease. The primary endpoint, MACE, was the time to first occurrence of a three-part composite outcome which included cardiovascular death, non-fatal myocardial infarction and non-fatal stroke.
Patients eligible to enter the trial were 50 years of age or older and had established, stable, cardiovascular, cerebrovascular, peripheral artery disease, chronic kidney disease or NYHA class II and III heart failure or were 60 years of age or older and had other specified risk factors for cardiovascular disease. In total, 1,797 patients (56.5%) had established cardiovascular disease without chronic kidney disease, 354 patients (11.1%) had chronic kidney disease only, and 544 patients (17.1%) had both cardiovascular disease and kidney disease; 488 patients (15.3%) had cardiovascular risk factors without established cardiovascular disease or chronic kidney disease. The mean age at baseline was 66 years, and 68% were men. The mean duration of diabetes was 14.9 years, and mean BMI was 32 kg/m2. Overall, 72% were White, 6% were Black or African American, and 20% were Asian; 16% identified as Hispanic or Latino ethnicity. Concomitant diseases of patients in this trial included, but were not limited to, heart failure (12%), history of ischemic stroke (8%) and history of a myocardial infarction (36%). In total, 99.7% of the patients completed the trial and the vital status was known at the end of the trial for 100%.
For the primary analysis, a Cox proportional hazards model was used to test for non-inferiority of RYBELSUS 14 mg to placebo for time to first MACE using a risk margin of 1.3. Type-1 error was controlled across multiple tests using a hierarchical testing strategy. Non-inferiority to placebo was established, with a hazard ratio equal to 0.79 (95% CI: 0.57, 1.11) over the median observation time of 16-months. The proportion of patients who experienced at least one MACE was 3.8% (61/1591) for RYBELSUS 14 mg and 4.8% (76/1592) for placebo.
