What is the recommended use of Liraglutide (glucagon-like peptide-1 receptor agonist) in adolescents with type 2 diabetes?

Liraglutide in Adolescents with Type 2 Diabetes

Liraglutide is FDA-approved and recommended for adolescents aged 10 years and older with type 2 diabetes when glycemic targets are not met with metformin alone, at doses up to 1.8 mg daily. 1, 2

Indications and Efficacy

• Liraglutide is one of only three FDA-approved medications (along with metformin and insulin) for the treatment of type 2 diabetes in youth aged 10 years and older 2
• Liraglutide should be considered when glycemic targets are not met with metformin (with or without basal insulin) 2
• Clinical trials demonstrated significant A1C reductions with liraglutide in adolescents:
  • 1.06 percentage point reduction at 26 weeks
  • 1.30 percentage point reduction at 52 weeks 3, 2
• Liraglutide is effective as an adjunct to diet and exercise to improve glycemic control 1

Dosing and Administration

• Start with lower doses and titrate up to minimize gastrointestinal side effects 2, 4
• Dosing can be escalated weekly: 0.3 mg → 0.6 mg → 0.9 mg → 1.2 mg → 1.8 mg daily 4
• Administer subcutaneously once daily, independent of meals 1
• The medication has a half-life of approximately 12 hours in adolescents, allowing for once-daily dosing 4

Safety Considerations

• Most common adverse events are gastrointestinal (nausea, vomiting, diarrhea) 3, 2
  • These typically decrease over time after initial treatment period 2, 5
• Risk of hypoglycemia is low due to the glucose-dependent mechanism of action 6
  • However, hypoglycemia risk is higher in pediatric patients compared to adults, particularly when used with insulin 1
• Contraindicated in patients with:
  • Personal or family history of medullary thyroid carcinoma
  • Multiple endocrine neoplasia syndrome type 2 1, 2
• No dose adjustment is required for renal impairment, but use with caution 1
• Use with caution in patients with hepatic impairment 1

Treatment Algorithm

1. Initial treatment approach:

   • For most newly diagnosed patients with type 2 diabetes, metformin is first-line therapy 2
   • For patients with marked hyperglycemia (blood glucose ≥250 mg/dL, A1C ≥8.5%) or ketosis, start with insulin plus metformin 2

2. When to add liraglutide:

   • Add when glycemic targets are not met with metformin alone 2
   • Consider in patients aged 10 years or older with no history of medullary thyroid carcinoma or MEN2 2

3. Monitoring and follow-up:

   • Assess glycemic response after 3 months
   • If inadequate response to maximum liraglutide dose, consider transitioning to multiple daily insulin injections 2
   • Monitor for gastrointestinal side effects, particularly during dose escalation 2

Multidisciplinary Approach

• A comprehensive diabetes care team is essential, including physician, diabetes educator, dietitian, and psychologist/social worker 2
• Treatment must address comorbidities such as obesity, dyslipidemia, hypertension, and microvascular complications 2
• Family-centered approach to nutrition and lifestyle modification is crucial 2

Important Caveats

• Liraglutide should not be used in patients with type 1 diabetes 1
• Do not coadminister with other liraglutide-containing products 1
• Limited long-term safety data exists specifically for adolescents compared to adults 2
• Weight effects are beneficial - liraglutide typically leads to weight loss or weight neutrality in adolescents with type 2 diabetes 3
• Use of medications not FDA-approved for youth with type 2 diabetes is not recommended outside of research trials 2
