Multizonal observational study conducted by clinical practitioners on Repatha® use in patients with hyperlipidemia (ZERBINI): Colombian results

Abstract

Background

Cardiovascular disease (CVD) represents the primary cause of death and disability globally, with elevated cholesterol as one of the leading risk factors for CVD. We describe the clinical characteristics, treatment patterns, and effectiveness of evolocumab in treating hyperlipidemia.

Methods

Observational study conducted through a chart review of patients with hyperlipidemia receiving evolocumab as part of clinical management in Colombia.

Results

This study included 115 patients treated with evolocumab. A total of 101 patients (87.8%) had a history of CVD, 13 (11.3%) familial hypercholesterolemia (FH), and 23 (20%) type 2 diabetes. Thirty-nine patients reported intolerance to any statin (33.9%). The median value of LDL-C before initiation of evolocumab was 147 mg/dL (IQR: 122.5–183.7 mg/dL). Within the first 3 months of treatment, LDL-C value dropped to a median value of 53 mg/dL (IQR: 34.0–95.5 mg/dL), showing a reduction of 63.9%. The median LDL-C values remained below 45 mg/dL until the end of follow-up. Among the patients with available data, up to 61% achieved an LDL-C level below 55 mg/dL at the 10–12-month follow-up. A total of 72% of patients were persistent with treatment. Safety results showed a low frequency of hospitalizations (≤2%) and treatment-emergent adverse drug reactions (5.2%). No serious adverse events were reported.

Conclusions

Evolocumab was associated with reductions in LDL-C levels, with a relative decrease of 63.9% within the first 3 months of treatment. Low rates of interruptions due to adverse events and adequate medication persistence was reported.
