Efficacy, Safety, and Pharmacokinetics of Inclisiran in Japanese Patients: Results from ORION-15. J Atheroscler Thromb 2024; 31:876-903. [PMID: 38220186 PMCID: PMC11150722 DOI: 10.5551/jat.64454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 11/08/2023] [Indexed: 01/16/2024] Open
Abstract
AIM To evaluate the efficacy, safety, and pharmacokinetics (PK) of inclisiran in Japanese patients with high cardiovascular risk and elevated low-density lipoprotein cholesterol (LDL-C). METHODS ORION-15 was a phase 2, double-blind, placebo-controlled randomized trial. Patients with hypercholesterolemia, including heterozygous familial hypercholesterolemia (HeFH), were randomized to inclisiran sodium 100, 200, or 300 mg, or placebo and dosed subcutaneously on Days 1, 90, and 270. The primary endpoint was the percentage change from baseline to Day 180 to demonstrate the superiority of inclisiran vs. placebo. Patients who consented to the PK substudy had additional study procedures for blood collection and safety assessment. RESULTS Overall, 312 patients (mean age, 63.6 years; male, 74.4%; baseline LDL-C, 114.0 mg/dL) were randomized. Baseline characteristics were well balanced among the groups. At Day 180, inclisiran at all doses demonstrated significant LDL-C and proprotein convertase subtilisin/kexin type 9 (PCSK9) reductions (p<0.0001 for both), which showed a dose-response relationship. The greatest reductions (LDL-C, 65.3%; PCSK9, 79.2%) were with inclisiran sodium 300 mg. At Day 180, >86% of the patients receiving inclisiran achieved the Japan Atherosclerosis Society 2017 lipid management targets compared to 8.9% for placebo. The mean (SD) plasma half-life for inclisiran was 6.8 (2.0)-7.6 (0.8) h. The incidence of adverse events with inclisiran was similar to that with placebo. CONCLUSION Inclisiran sodium 100, 200, and 300 mg demonstrated clinically meaningful and statistically significant LDL-C and PCSK9 reductions at Day 180, which were consistent over 12 months. Inclisiran was effective and well tolerated in Japanese patients with hypercholesterolemia, including HeFH.

Long-term Efficacy and Safety of K-924 Pitavastatin/Ezetimibe Fixed-dose Combination in Patients with Hypercholesterolemia: A Phase III, Multi-center, Open-label Trial. J Atheroscler Thromb 2024; 31:288-305.

Abstract
AIM Ezetimibe administration with ongoing statin therapy is an effective option for further lowering low-density lipoprotein cholesterol (LDL-C) levels. Thus, we investigated the long-term efficacy and safety of fixed-dose combination of pitavastatin/ezetimibe (K-924 LD: 2 mg/10 mg; K-924 HD: 4 mg/10 mg). METHODS We conducted a phase III, multicenter, open-label trial involving patients with hypercholesterolemia receiving pitavastatin (2 or 4 mg) who had not achieved their LDL-C management target. Patients were enrolled into the K-924 LD and HD groups based on whether they had received pitavastatin 2 and 4 mg, respectively, and treated for 52 weeks. K-924 was administered orally once daily. The primary objective was to examine the percent change in LDL-C from baseline at week 52 with last observation carried forward imputation (LOCF) in all patients. RESULTS Of the 109 patients evaluated, 62 and 47 were assigned to the K-924 LD and HD groups, respectively. In all patients, LDL-C decreased by -30.3±14.3% (p<0.001) from baseline (134.4±37.9 mg/dL). Consequently, 91.8% and 37.5% of the patients for primary and secondary prevention reached their LDL-C management target, respectively. These results were consistent in both the K-924 LD and HD groups. In the safety analysis, a single adverse drug reaction occurred in a patient in the K-924 HD group. CONCLUSION After replacing pitavastatin monotherapy, K-924 was found to be effective and well-tolerated over 52 weeks. Thus, K-924 can contribute to intensifying LDL-C-lowering therapy without increasing the number of medications.

Abstract
AIMS The study aimed to investigate low-density lipoprotein cholesterol (LDL-C) goal achievement rates in patients receiving LDL-C-lowering therapy using recent real-world data, following the 2017 revision of the Japan Atherosclerosis Society Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases (JAS GL2017). METHODS Patients with documented LDL-C test results were extracted from the Medical Data Vision claims database between July 2018 and June 2021 and divided into three groups according to JAS GL2017: primary prevention high risk (Group I, LDL-C goal <120 mg/dL), secondary prevention (Group II, LDL-C goal <100 mg/dL), and secondary prevention high risk (Group III, LDL-C goal <70 mg/dL). RESULTS The mean LDL-C value was 108.7 mg/dL (n=125,235), 94.4 mg/dL (n=57,910), and 90.6 mg/dL (n=33,850) in Groups I, II, and III, respectively. Intensive statin monotherapy (pitavastatin, rosuvastatin, or atorvastatin) was the most frequently prescribed lipid-lowering treatment (21.6%, 30.8%, and 42.7% in Groups I, II, and III, respectively), followed by ezetimibe (2.5%, 7.1%, and 8.5% in Groups I, II, and III, respectively). LDL-C goals were achieved by 65.5%, 60.6%, and 25.4% of patients overall in Groups I, II, and III, respectively. Achievement rates were 83.9%, 75.3%, and 29.5% in patients prescribed intensive statin monotherapy and 82.3%, 86.4%, and 46.4% in those prescribed statin and ezetimibe combinations in Groups I, II, and III, respectively. In Group III, the proportion of patients with familial hypercholesterolemia prescribed statin and ezetimibe combinations achieving LDL-C goals was low (32.5%). CONCLUSIONS The proportion of patients achieving LDL-C goals for secondary prevention in the high-risk group remains low even with statin and ezetimibe combination therapy.

Efficacy and Safety of Pitavastatin/Ezetimibe Fixed-Dose Combination vs. Pitavastatin: Phase III, Double-Blind, Randomized Controlled Trial. J Atheroscler Thromb 2023; 30:1580-1600. [PMID: 36908150 PMCID: PMC10627746 DOI: 10.5551/jat.64006] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 01/23/2023] [Indexed: 03/13/2023] Open
Abstract
AIM We compared the efficacy and safety of pitavastatin/ezetimibe fixed-dose combination with those of pitavastatin monotherapy in patients with hypercholesterolemia. METHODS This trial was a multicenter, randomized, double-blind, active-controlled, parallel-group trial. A total of 293 patients were randomly assigned into four groups receiving 2 mg pitavastatin, 4 mg pitavastatin, 2 mg pitavastatin/10 mg ezetimibe (K-924 LD), and 4 mg pitavastatin/10 mg ezetimibe (K-924 HD) once daily for 12 weeks. RESULTS The percentage changes in low-density lipoprotein cholesterol (LDL-C), the primary endpoint, were -39.5% for 2 mg pitavastatin, -45.2% for 4 mg pitavastatin, -51.4% for K-924 LD, and -57.8% for K-924 HD. Compared with pitavastatin monotherapy, the pitavastatin/ezetimibe fixed-dose combination significantly reduced LDL-C, total cholesterol, and non-high-density lipoprotein cholesterol. Meanwhile, the cholesterol synthesis marker, lathosterol, was significantly decreased with pitavastatin monotherapy and the pitavastatin/ezetimibe fixed-dose combination, although the decrease was attenuated in the latter. On the other hand, the cholesterol absorption markers, beta-sitosterol and campesterol, were reduced with the fixed-dose combination but not with pitavastatin monotherapy. The incidence of adverse events and adverse drug reactions was not significantly different between the two groups receiving the fixed-dose combination and monotherapy. The mean values of laboratory tests that are related to liver function and myopathy increased but remained within the reference range in all groups. CONCLUSIONS The pitavastatin/ezetimibe fixed-dose combination showed an excellent LDL-C-reducing effect by the complementary pharmacological action of each component, and its safety profile was similar to that of pitavastatin monotherapy (ClinicalTrials.gov Identifier: NCT04289649).

Abstract
BACKGROUND Statins are expected to have beneficial effects on nonalcoholic fatty liver disease (NAFLD); however, evidence remains insufficient. OBJECTIVE In this study, we aim to investigate the association between statin adherence and NAFLD development. METHODS We conducted a nested case-control study of statin users using the Japan Medical Data Center administrative claims database (January 2005 to January 2020). Individuals who developed NAFLD were designated as cases. For each case, we randomly selected a maximum of 10 controls using risk set sampling. Good adherence was defined as the proportion of days covered (PDC) of ≥0.80. Higher intensity was defined as the median or higher of a cumulative defined daily dose (cDDD) per day covered by statin prescription. Conditional logistic regression analysis was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS In this study, 253 383 patients with the first statin prescription were identified. Of them, 7080 were selected and matched to 70 734 controls. The medians of PDC and intensity were 0.88 (interquartile range [IQR], 0.61-0.96) and 0.32 (IQR, 0.25-0.50) cDDD/day, respectively. Good adherence was significantly associated with a reduced risk of NAFLD development (adjusted OR, 0.82; 95% CI, 0.78-0.86). Higher intensity was not significantly associated with a reduced risk of NAFLD development (adjusted OR, 1.02; 95% CI, 0.97-1.08). CONCLUSION AND RELEVANCE Good adherence to statins is associated with a reduced risk of NAFLD development, regardless of the statin intensity. Appropriate statin therapy could reduce the risk of NAFLD development.

Guanxinshutong Alleviates Atherosclerosis by Suppressing Oxidative Stress and Proinflammation in ApoE -/- Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:1219371. [PMID: 33014098 PMCID: PMC7519182 DOI: 10.1155/2020/1219371] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 08/20/2020] [Accepted: 09/08/2020] [Indexed: 01/01/2023]
Abstract
Atherosclerosis (AS) is a chronic progressive disease related to dyslipidemia, inflammation, and oxidative stress. Guanxinshutong capsule (GXST), a traditional Chinese medicine, has been widely used in treating coronary atherosclerotic heart disease, while its mechanism actions on AS are still not to be well addressed. Our present study is aimed to examine the effect of GXST on AS and elucidate the multitarget mechanisms of GXST on AS. Network pharmacology analysis was employed to screen the multitarget mechanisms of GXST on AS. ApoE−/− mice were used to validate these effects. Circulating lipid profile and oxidative stress-related factors were measured by the Elisa kit. Furthermore, the aortic trunk and aortic root were excised for oil red O staining, histopathological and immunohistochemical analysis. We first discovered that GXST was clued to exert synergistically antiatherosclerosis properties including lipid-lowering, anti-inflammation, and antioxidation through the computational prediction based on a network pharmacology simulation. Next, the validation experiments in atherosclerosis mice provided evidence that GXST significantly reduced atherosclerotic lesions, increased collagen deposition, and attenuated LV remodeling to some extent. Mechanistically, GXST modulated lipid profile, downregulated the level of inflammatory cytokines and NF-κBp65. GXST also reduced the activity of oxidative parameter MDA and upregulated the activities of antioxidant enzymes (SOD and GSH) compared with the AS model group. In conclusion, GXST intervention might attenuate atherosclerosis by mechanisms involving reducing lipid deposition, modulating oxidative stress and inflammatory responses, but a larger controlled trial is necessary for confirmation.

Abstract
Background Use of ezetimibe on top of statin therapy has been shown to be effective to reduce LDL cholesterol level in hypercholesterolemic patients. However, little is known regarding the individual variety of the effectiveness of ezetimibe. We hypothesized that hypercholesterolemic patients with a mutation in ABCG5 or ABCG8 gene exhibit better response to ezetimibe than those without, based on the fact that ezetimibe is hyper-effective for in patients with sitosterolemia caused by ABCG5 or ABCG8 genetic mutations. Methods Electronical medical record were reviewed in a total of 321 hypercholesterolemic patients (baseline LDL cholesterol = 192 ± 46 mg/dl) prescribed ezetimibe 10 mg daily on top of atorvastatin 10 mg daily who had undergone genetic analysis of ABCG5 or ABCG8 gene in our institute since 2006 to 2017. Pathogenicity of the variants were determined using standard variant filtering schema, including minor allele frequency, in silico annotation tools. Patients were divided into 2 groups based on the presence of ABCG5 or ABCG8 mutation. We compared the percent reduction of LDL cholesterol as well as the achieved LDL cholesterol levels between these 2 groups. Results We found 26 (8%) individuals who exhibit deleterious mutations in ABCG5 or ABCG8 gene. Baseline characteristics under the atorvastatin 10 mg therapy were comparable in age, gender, and LDL cholesterol level between 2 groups. Under these conditions, percent reduction of LDL cholesterol in mutation positive group was significantly larger than that of mutation negative group (28 ± 16% vs. 39 ± 21%, p < 0.05). As a result, the achieved LDL cholesterol level in mutation positive group was significantly lower than that of mutation negative group (87 ± 29 mg/dl vs. 72 ± 26% mg/dl, p < 0.05). Conclusion These results suggest that ezetimibe-atorvastatin combination therapy might be more beneficial in hypercholesterolemic patients with a mutation in ABCG5 or ABCG8 gene.

Adherence and persistence to hyperlipidemia medications in patients with atherosclerotic cardiovascular disease and those with diabetes mellitus based on administrative claims data in Japan. Atherosclerosis 2018; 282:19-28. [PMID: 30669019 DOI: 10.1016/j.atherosclerosis.2018.12.026] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Revised: 12/13/2018] [Accepted: 12/21/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND AND AIMS Real-world data on treatment patterns in Japanese hyperlipidemia patients with diabetes mellitus (DM) or prior atherosclerotic cardiovascular diseases (ASCVD) are lacking. METHODS This is a retrospective, longitudinal cohort analysis of administrative claims data (Japan Medical Data Center [JMDC] and Medical Data Vision [MDV] databases) for patients prescribed a new hyperlipidemia medication between 2014 and 2015. Patients were followed for ≥12 months. Outcomes included prescribing patterns, persistence (discontinuations), and adherence (proportion of days covered). RESULTS Data were analyzed for 11,718 and 27,746 DM, and 4101 and 14,356 ASCVD patients from the JMDC and MDV databases, respectively. Among previously-untreated patients, index prescriptions were primarily for moderate statins in the DM (JMDC: 74.7%, MDV: 77.5%) and ASCVD (JMDC: 75.4%, MDV: 78.5%) sub-cohorts. Combinations were rarely prescribed (≤2.5%). Previously-treated patients were most frequently prescribed combinations in the DM (JMDC: 46.7%, MDV: 53.6%) and ASCVD (JMDC: 49.3%, MDV: 53.3%) sub-cohorts. Intensive statins were rarely used by previously-untreated (≤1%) or previously-treated (≤8%) patients in either sub-cohort. Approximately half of previously-untreated patients discontinued hyperlipidemia therapy within 12 months. Adherence was ≥80% across most drug classes. CONCLUSIONS Many Japanese hyperlipidemia patients with DM or ASCVD are prescribed single-agent lipid-lowering therapy. Use of intensive therapy is lower than expected, and is suggestive of under-treatment. The low persistence rates are concerning, and warrant further study.
