505-P: Real-World Use of Inclisiran in Outpatient Physician Clinics

Abstract

Objective: In clinical trials, inclisiran, a novel siRNA therapy, reduced LDL-C equally among diabetic and nondiabetic patients. This study aimed to characterize a cohort of obese, prediabetic, and diabetic patients prior to initiating inclisiran in outpatient clinics. Methods: This was a retrospective, longitudinal cohort study of patients referred for treatment with inclisiran between February and November 2022 in 23 clinics in 11 states. Patients with obesity (BMI>30 kg/m2), prediabetes (5.7≤ HbA1c≤ 6.5%), or diagnosed diabetes at the time of referral were assessed. The log rank test was used to identify differences in time from referral to first administration between above groups. Results: Of 81 identified patients, 48.2% were diabetic, 27.2% obese, and 24.7% prediabetic. Median age was 71 (IQR: 68-75) years, 60.5% were male, and 60.5% were Medicare beneficiaries. At referral, 81.4% had a primary diagnosis of atherosclerotic cardiovascular disease (ASCVD), 30.9% were on concurrent statins, 30.9% on ezetimibe, 66.7% had documented statin intolerance, 50.6% had prior PCSK9 monoclonal antibody use, and the median Elixhauser comorbidity score was 6.0 (IQR: 2-15). Elixhauser score was notably higher among the diabetic group (Median: 9, IQR: 3-18) compared to the prediabetic (Median: 4, IQR: 0-13) and obese (Median: 3, IQR: -3-12) patient groups. Median baseline LDL-C was 135 (IQR: 99-166) mg/dL with no differences between groups. Median time to initiation was 27 (IQR: 16-49) days with no notable difference between obese, prediabetic, and diabetic patients. Conclusion: Inclisiran can be promptly initiated in the clinic setting for the management of LDL-C in obese, prediabetic, and diabetic patients. Future work will focus on measuring real-world effectiveness and adherence to inclisiran in each of these groups. Disclosure T.E. Graham: None. T.J. Varisco: Consultant; HEALIX. C.M.
