    Mechanism of Action

    Semaglutide is a GLP-1 analogue that selectively binds to and activates the GLP-1 receptor. GLP-1 is a physiological regulator of appetite and caloric intake, and the GLP-1 receptor is present in several areas of the brain involved in appetite regulation.

    Wegovy Indications

    Indications

    As an adjunct to a reduced calorie diet and increased physical activity for chronic weight management in: adults with an initial body mass index (BMI) of ≥30kg/m2 (obese) or ≥27kg/m2 (overweight) in the presence of at least 1 weight-related comorbid condition (eg, hypertension, T2DM, dyslipidemia); and pediatric patients with an initial BMI at the 95th percentile or greater standardized for age and sex (obesity).

    Limitations of Use

    Do not use with other semaglutide-containing products or with any other GLP-1 receptor agonist. Safety and efficacy have not been established with other products intended for weight loss, including prescription drugs, OTC drugs, and herbal preparations. Not studied in those with a history of pancreatitis.

    Warnings/Precautions

    Risk of Thyroid C-Cell Tumors

    • Not known whether Wegovy causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans.

    • Counsel patients associated with the potential risk of MTC and inform patients of symptoms associated with thyroid tumors (eg, mass in the neck, dysphagia, dyspnea, persistent hoarseness).

    • Monitor routinely serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC. This may increase the risk of unnecessary procedures. Patients with MTC usually have calcitonin values >50 ng/L.

    • Evaluate further if serum calcitonin is found to be elevated, or if thyroid nodules are noted on physical examination.

    Acute Pancreatitis

    • Following initiation, monitor carefully for signs and symptoms of acute pancreatitis, including persistent severe abdominal pain, sometimes radiating to the back, and which may or may not be accompanied by vomiting.

    • Prompt discontinue treatment if acute pancreatitis is suspected and initiate appropriate management. Do not restart treatment if acute pancreatitis is confirmed.

    • Wegovy has not been studied in patients with history of pancreatitis. Not known if patients with a history of pancreatitis are at higher risk.

    Acute Gallbladder Disease

    • In clinical trials, cholelithiasis and cholecystitis was reported by 1.6% and 0.6%, respectively, of Wegovy-treated patients and 0.7% and 0.2% of placebo-treated patients.

    • Initiate gallbladder studies and appropriate clinical follow-up if cholelithiasis is suspected.

    Hypoglycemia

    • Patients with type 2 diabetes mellitus taking Wegovy in combination with an insulin secretagogue may have an increased risk of hypoglycemia.

    • Advise patients of the risk of the signs and symptoms of hypoglycemia. Prior to initiating and during treatment, monitor blood glucose in patients with type 2 diabetes. Upon initiating treatment, consider reduce dose of concomitant insulin secretagogue or insulin.

    Acute Kidney Injury 

    • Patients with renal impairment may have greater risk of acute kidney injury.

    • Monitor renal function when initiating or escalating doses. Monitor renal function in patients with renal impairment reporting any adverse reactions that could lead to volume depletion.

    Hypersensitivity

    • Discontinue and treat promptly per standard of care if hypersensitivity reactions occur, then monitor until signs and symptoms resolve.

    • Use caution in patients with a history of anaphylaxis or angioedema with another GLP-1 receptor agonist.

    Diabetic Retinopathy Complications in Patients with Type 2 Diabetes

    • Risk of temporary worsening of diabetic retinopathy with a rapid improvement in glucose control.

    • Wegovy has not been studied for the effect of long-term glycemic control on diabetic retinopathy complications.

    • Monitor patients for progression of diabetic retinopathy in patients with a history of diabetic retinopathy.

    Heart Rate Increase

    • Monitor heart rate at regular intervals.

    • Advise patients to inform their healthcare providers of palpitations or feelings of a racing heartbeat while at rest during treatment.

    • Discontinue treatment if a sustained increase in resting heart rate occurs.

    Suicidal Behavior and Ideation

    • Monitor for emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior.

    • Discontinue treatment if suicidal thoughts or behaviors occur.

    • Avoid in patients with a history of suicidal attempts or active suicidal ideation.

    Pregnancy Considerations

    Pregnancy Exposure Registry

    • There will be a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to semaglutide during pregnancy. Pregnant women exposed to Wegovy and healthcare providers are encouraged to contact Novo Nordisk at 1-800-727-6500.

    Risk Summary

    • Based on animal reproduction studies, there may be potential risks to the fetus from exposure to semaglutide during pregnancy.

    • Advise pregnant patient of the risk of fetal harm when pregnancy is recognized and discontinue treatment.

    Clinical Considerations

    • Disease-associated maternal and/or embryo/fetal risk: Appropriate weight gain based on pre-pregnancy weight is currently recommended for all pregnant patients, including those who already have overweight or obesity, because of the obligatory weight gain that occurs in maternal tissues during pregnancy. 

    Nursing Mother Considerations

    Risk Summary

    • No data on the presence of semaglutide or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production.

    • Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for Wegovy and any potential adverse effects on the breastfed infant from Wegovy or from the underlying maternal condition. 

    Pediatric Considerations

    Safety and efficacy of Wegovy have not been established in pediatric patients.

    Geriatric Considerations

    No overall differences in safety or efficacy were detected between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

    Renal Impairment Considerations

    No dose adjustment is recommended.

    Hepatic Impairment Considerations

    No dose adjustment is recommended.

    Other Considerations for Specific Populations

    Females and Males of Reproductive Potential  

    • Discontinue treatment in patients at least 2 months before they plan to become pregnant.

    Wegovy Pharmacokinetics

    Absorption

    Absolute bioavailability of semaglutide is 89%. Maximum concentration of semaglutide is reached 1 to 3 days post dose. Similar exposure was achieved with subcutaneous administration of semaglutide in the abdomen, thigh, or upper arm. The average semaglutide steady state concentration following subcutaneous administration of Wegovy was ~75 nmol/L in patients with either obesity (BMI ≥30 kg/m2) or overweight (BMI ≥27 kg/m2). The steady state exposure of Wegovy increased proportionally with doses up to 2.4 mg once-weekly. 

    Distribution

    The mean volume of distribution of semaglutide following subcutaneous administration in patients with obesity or overweight is approximately 12.5 L. Semaglutide is extensively bound to plasma albumin (>99%) which results in decreased renal clearance and protection from degradation. 

    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 sidechain. 

    Elimination

    With an elimination half-life of ~1 week, semaglutide will be present in the circulation for about 5 to 7 weeks after the last dose of 2.4 mg. 

    The primary excretion routes of semaglutide-related material are via the urine and feces. Approximately 3% of the dose is excreted in the urine as intact semaglutide.

    Wegovy Interactions

    Interactions

    Increased risk of hypoglycemia with concomitant insulin secretagogues (eg, sulfonylureas) or insulin; may need a lower dose of these. May affect absorption of other oral drugs (delayed gastric emptying); caution.

    Wegovy Adverse Reactions

    Adverse Reactions

    Nausea, diarrhea, vomiting, constipation, abdominal pain/distension, headache, fatigue, dyspepsia, dizziness, eructation, hypoglycemia in T2DM, flatulence, gastroenteritis, GERD, nasopharyngitis; acute kidney injury, retinal disorders, lab abnormalities (eg, increased lipase or amylase), hypersensitivity reactions.

    Wegovy Clinical Trials

    Clinical Trials

    The approval was based on three 68-week double-blind, placebo-controlled studies (Studies 1, 2, 3), in which Wegovy or placebo was escalated to 2.4mg subcutaneous weekly during a 16-week period followed by 52 weeks on maintenance dose, as well as one 68-week withdrawal trial (Study 4), in which Wegovy was escalated during a 20-week run-in period, and patients who reached 2.4mg after the run-in period were randomly assigned to either continue treatment or placebo for 48 weeks.

    In Studies 1, 2, and 3, the primary efficacy endpoints were mean percent change in body weight and the percentages of patients achieving greater than or equal to 5% weight loss from baseline to week 68. Findings from these studies showed that treatment with Wegovy resulted in statistically significant reductions in body weight, with a greater proportion of patients achieving 5%, 10%, and 15% weight loss, compared with placebo.

    Study 1 (ClinicalTrials.gov Identifier: NCT03548935) included 1961 patients with obesity or with overweight and at least 1 weight-related comorbid condition; mean baseline body weight was 105.3 kg and mean BMI was 37.9 kg/m2. Wegovy-treated patients (n=1306) lost an average of 12.4% (95% CI, -13.3, -11.6) of their initial body weight compared with those who received placebo (n=655) (P <.0001).

    Study 2 (ClinicalTrials.gov Identifier: NCT03552757) enrolled 807 patients with type 2 diabetes and a BMI of at least 27 kg/m2; mean baseline body weight was 99.8 kg and mean BMI was 35.7 kg/m2. In this study, patients who received Wegovy (n=404) lost an average of 6.2% (95% CI, -7.3, -5.2) of their initial body weight compared with placebo (n=403) (P <.0001).

    Study 3 (ClinicalTrials.gov Identifier: NCT03611582) included 611 patients with obesity or with overweight and at least 1 weight-related comorbid condition who were undergoing intensive lifestyle therapy; mean baseline body weight was 105.8 kg and mean BMI was 38.0 kg/m2. Findings showed that Wegovy-treated patients (n=407) lost an average of 10.3% (95% CI, -11.8, -8.7) of their initial body weight compared with placebo (n=204) (P <. 0001).

    In Study 4 (ClinicalTrials.gov Identifier: NCT03548987), the primary efficacy measure was mean percent change in body weight from randomization (week 20) to week 68. The mean body weight change was observed to be -7.9% with continued Wegovy treatment vs +6.9% with placebo (% difference from placebo, -14.8 [95% CI, -16.0, -13.5]; P <.001).
