Is Wegovy (semaglutide) a suitable treatment option for a 36-year-old male, 67 inches tall and weighing 250 pounds, with a history of hypercholesterolemia and fatty liver disease, who has an impaired fasting glucose level (A1c of 5.7), and has had limited weight loss success despite a year of daily 40-minute exercise and a low-calorie diet, and has recently stopped alcohol consumption?

Prior Authorization Note for Wegovy (Semaglutide) Initiation

Patient Demographics and Clinical Presentation

This 36-year-old male with BMI 36.8 kg/m² (67 inches, 250 lbs), prediabetes (A1c 5.7%), hypercholesterolemia, and non-alcoholic fatty liver disease meets criteria for GLP-1 receptor agonist therapy with Wegovy. 1

Medical Necessity Justification

Obesity Classification and Comorbidities

• BMI 36.8 kg/m² qualifies as Class II obesity 1
• Prediabetes (A1c 5.7%) indicates high risk for progression to type 2 diabetes and cardiovascular disease 1
• Non-alcoholic fatty liver disease (NAFLD/MASLD) with obesity represents significant metabolic dysfunction requiring aggressive intervention 1, 2
• Hypercholesterolemia further elevates cardiovascular risk 1

Documentation of Lifestyle Modification Failure

The patient has demonstrated inadequate response to comprehensive lifestyle interventions over 12 months, meeting criteria for pharmacotherapy: 1

• Daily exercise: 40 minutes per day (exceeds the recommended 150-300 minutes per week of moderate-intensity activity) 1
• Hypocaloric diet implementation for 12 months 1
• Alcohol cessation (critical for NAFLD management) 1
• Despite these intensive lifestyle modifications, the patient has achieved minimal weight loss, indicating the need for pharmacologic augmentation 1

Rationale for Wegovy (Semaglutide 2.4 mg) Selection

Evidence-Based Superiority for This Patient Profile

Semaglutide represents the optimal pharmacotherapy choice for this patient based on multiple compelling factors: 1

Weight Loss Efficacy

• Semaglutide 2.4 mg weekly achieves mean weight loss of 15-25%, significantly superior to other anti-obesity medications 1
• The patient requires substantial weight reduction (target 7-10% minimum) to improve NAFLD histology and prevent diabetes progression 1, 2
• Weight loss of 7-10% can lead to NASH resolution and fibrosis regression 1, 2

Metabolic Benefits Beyond Weight Loss

• GLP-1 receptor agonists reduce progression from prediabetes to type 2 diabetes 1
• Semaglutide improves cardiovascular outcomes in high-risk patients, addressing this patient's multiple cardiovascular risk factors 1
• GLP-1 agonists demonstrate specific benefits for NAFLD/MASLD, including improvements in liver enzymes (ALT), hepatic steatosis, and liver fibrosis markers 2, 3, 4, 5, 6, 7, 8

NAFLD-Specific Evidence

• Semaglutide 2.4 mg received FDA accelerated approval for MASH with moderate to advanced fibrosis (F2-F3), demonstrating 62.9% MASH resolution vs 34.3% placebo and 36.8% fibrosis improvement vs 22.4% placebo at 72 weeks 4
• Meta-analyses confirm semaglutide significantly reduces ALT, liver stiffness (fibroscan), hepatic steatosis, and improves fibrosis markers 5, 6, 7, 8
• The hepatic steatosis index (HSI) and fibrosis-4 (FIB-4) index improve significantly with semaglutide treatment 7, 8

Safety Profile

• Lower hypoglycemia risk compared to insulin or sulfonylureas, particularly important given prediabetic state 1
• Favorable hepatic safety profile with no discontinuations due to liver enzyme elevations in clinical trials 4
• No dose adjustment required for hepatic or renal impairment 9

Superiority Over Alternative Therapies

Alternative anti-obesity medications are less appropriate for this patient: 1

• Phentermine: Contraindicated or less preferred in patients with cardiovascular risk factors; lacks metabolic benefits for prediabetes and NAFLD 1
• Orlistat: Mean weight loss only 3.1% at 1 year; failed to improve liver histology in NAFLD trials 1
• Lorcaserin: Lower efficacy (3.6% weight loss); lacks specific NAFLD benefits 1
• Naltrexone/bupropion: Mean weight loss 4.8%; no specific evidence for NAFLD improvement 1

Clinical Goals and Expected Outcomes

Primary Objectives

1. Achieve 7-10% total body weight loss (17.5-25 lbs) to improve NAFLD histology and prevent diabetes progression 1, 2
2. Reduce A1c below prediabetic threshold (<5.7%) to decrease diabetes risk 1
3. Improve hepatic steatosis and prevent fibrosis progression 2, 3, 4
4. Optimize cardiovascular risk profile through weight reduction and metabolic improvements 1

Monitoring Plan

• Monthly assessment for first 3 months during dose titration, then quarterly 1
• Evaluate weight loss, A1c, lipid panel, and liver enzymes (ALT/AST) at 3-6 month intervals 2, 3, 4
• Reassess efficacy at 12 weeks: discontinue if <5% weight loss achieved 1
• Monitor for gastrointestinal adverse effects (nausea, diarrhea, vomiting) during titration; educate patient on expected transient nature 4
• Screen for rare serious adverse events: acute kidney injury (ensure adequate hydration), symptomatic gallbladder disease, pancreatitis 4

Dosing Protocol

Wegovy (semaglutide) subcutaneous injection with standard dose escalation: 9, 4

• Weeks 1-4: 0.25 mg once weekly
• Weeks 5-8: 0.5 mg once weekly
• Weeks 9-12: 1.0 mg once weekly
• Weeks 13-16: 1.7 mg once weekly
• Week 17 onward: 2.4 mg once weekly (maintenance dose)

Contraindications and Precautions Reviewed

• No personal or family history of medullary thyroid carcinoma or MEN 2 syndrome 9
• No history of pancreatitis 9, 4
• Renal and hepatic function adequate (no dose adjustment required) 9
• Patient counseled on gastrointestinal side effects and importance of hydration 4

Conclusion

This patient meets established criteria for GLP-1 receptor agonist therapy with Wegovy based on Class II obesity (BMI 36.8), multiple metabolic comorbidities (prediabetes, NAFLD, hypercholesterolemia), and documented failure of intensive lifestyle interventions over 12 months. 1, 2 Semaglutide 2.4 mg weekly represents the most evidence-based pharmacotherapy to achieve clinically meaningful weight loss, prevent diabetes progression, improve NAFLD histology, and reduce cardiovascular risk in this high-risk patient. 1, 2, 4

Approval of Wegovy is medically necessary and represents standard-of-care treatment for this clinical presentation.
