Abstract Disclosure: G. Castano: None. S. Sisley: None. Background: Glucagon-like-peptide-1 agonists (GLP1), approved for adolescents ≥ 10 years in 2019 for type 2 diabetes (T2D) and ≥ 12 years in 2020 for obesity, require adequate dose titration and have known side effects. There is little information on insurance approval, adherence to titration regimens, or the side effects of liraglutide in clinical practice. Methodology: We performed a retrospective review of all patients 18 years old who were prescribed GLP-1 at a large children’s hospital. We collected demographic information, prescription orders, insurance approval, and drug initiation dates. For individuals who completed at least 26±8 weeks of treatment, we also collected dose titration, side effects, and insulin doses. Results:599 patients were prescribed GLP-1 from 2019 to 2023, with a mean age of 14.99±2.1 years, 58% female, 58% public insurance, and 74% (n=442) with T2D. The cohort was comprised of 63% White, 30% Black, and 2.3% Asian individuals, with 52% of Hispanic ethnicity. 90% of prescriptions were for liraglutide, and 10% for other GLP1 analogs, including exenatide, dulaglutide, and semaglutide. Insurance denied 41% (n=244) of prescriptions, with more denials in those without T2D, 64% vs 32% in patients with T2D.Whereas private insurance denied more prescriptions than Medicaid in patients with T2D (54% vs 27%), the reverse was true for patients without T2D ( 55% private vs 69% Medicaid). Patients lost to follow-up in the first 3 months accounted for 22% (n=135) of the cohort, even though 48% (n=66) of those patients had insurance approval.Those who had insurance approval and took liraglutide for at least 26 weeks accounted for 34% (n=204) of the cohort. Of the patients with T2D, 50% (n=95) titrated to 1.8mg by their first follow-up appointment (1-3 months after prescription start), 33% (n=62) by 6 months, and 17% (n=32) never reached 1.8mg. In patients prescribed a higher dose of liraglutide (3.0 mg daily), 42% (n=8) titrated to 3mg over 5 weeks as prescribed, and 52% (n=10) never reached 3mg, with only one of them not reaching 1.8 mg.Most patients (82%, n=169) had no side effects documented in their charts. From those with side effects reported, GI problems (nausea, vomiting, diarrhea) were noted in 12% (n=25), and 2% (n=4) reported injection site reactions. Side effects that required medication discontinuation included hypoglycemia (n=1), mild pancreatitis (n=1), and severe pancreatitis (n=2). Conclusion: In clinical practice, despite FDA approval, insurance coverage of liraglutide is limited. Almost half of the patients require extra time to reach full doses of liraglutide, with one-third never reaching full treatment doses. Severe pancreatitis may be a previously unpublished side effect. More research is needed to understand how real-world adherence and side effects of liraglutide affect clinical outcomes. Presentation: 6/1/2024
