Dyslipidemia accompanied by metabolic syndrome substantially elevates cardiovascular risk by clustering multiple risk factors, including abdominal obesity, hypertension, hyperglycemia, and atherogenic dyslipidemia. The prevalence of both conditions is rising in Korea, underscoring the need for effective and metabolically safe lipid-lowering therapy. LivaloZet® Tablet (pitavastatin/ezetimibe fixed-dose combination) addresses this need by combining complementary cholesterol-lowering mechanisms with the glucose-neutral profile of pitavastatin. The PIVOT study is a multi-center, non-interventional, prospective observational study enrolling up to 10,000 Korean adult patients with dyslipidemia accompanied by metabolic syndrome who have been prescribed LivaloZet® Tablets (pitavastatin/ezetimibe 2/10 mg or 4/10 mg) by their treating physician as part of routine clinical care. Metabolic syndrome is defined according to the modified NCEP-ATP III criteria for the Asian population. Assessments are conducted at baseline, Week 24, and Week 48. The primary endpoint is the percent change in low-density lipoprotein cholesterol (LDL-C) from baseline at Week 24. Secondary endpoints include LDL-C changes at Week 48, changes in the full lipid panel, and LDL-C target achievement rates by cardiovascular risk group. Exploratory endpoints encompass glucose metabolism parameters (HbA1c, HOMA-IR, HOMA-β), medication adherence and persistence, and high-sensitivity C-reactive protein. Safety is assessed through adverse events, laboratory tests, and vital signs, including systematic monitoring of AST, ALT, and creatine kinase for statin-related hepatotoxicity and myopathy. The study was approved by the Institutional Review Board of Chungnam National University Hospital (2025-07-065) and is registered at ClinicalTrials.gov (NCT07523971). The PIVOT study will generate prospective large-scale real-world evidence on the LDL-C-lowering effectiveness and safety patterns associated with use of a pitavastatin/ezetimibe fixed-dose combination in Korean patients with dyslipidemia accompanied by metabolic syndrome. The inclusion of glucose metabolism and inflammatory markers will provide descriptive information on the metabolic safety profile of this regimen. As a non-randomized, single-arm observational study, this design cannot establish causal effects or comparative efficacy versus other lipid-lowering regimens. Findings should be interpreted descriptively, acknowledging potential confounding by indication, selection bias, and inter-laboratory variability.
