Safety and Pharmacokinetics of Glecaprevir/Pibrentasvir in Adults With Chronic Genotype 1-6 Hepatitis C Virus Infections and Compensated Liver Disease.

BACKGROUND: Untreated, chronic hepatitis C virus (HCV) infection may lead to progressive liver damage, which can be mitigated by successful treatment. This integrated analysis reports the safety, efficacy, and pharmacokinetics (PK) of the ribavirin-free, direct-acting, antiviral, fixed-dose combination of glecaprevir/pibrentasvir (G/P) in patients with chronic HCV genotype 1-6 infections and compensated liver disease, including patients with chronic kidney disease stages 4 or 5 (CKD 4/5). METHODS: Data from 9 Phase II and III clinical trials, assessing the efficacy and safety of G/P treatment for 8-16 weeks, were included. The presence of cirrhosis was determined at screening using a liver biopsy, transient elastography, or serum biomarkers. The objectives were to evaluate safety, the rate of sustained virologic response at post-treatment week 12 (SVR12), and steady-state PK by cirrhosis status. RESULTS: Among 2369 patients, 308 (13%) were Child-Pugh Class A, including 20 with CKD 4/5. Overall, <1% of patients experienced an adverse event (AE) that led to G/P discontinuation or G/P-related serious AEs (SAEs). The most common AEs were headache and fatigue, occurring at similar frequencies with and without cirrhosis. SAEs were more common in patients with CKD 4/5, but all were unrelated to G/P. There were no cases of drug-induced liver injury or clinically relevant hepatic decompensation. SVR12 rates were 96.4% (297/308) with compensated cirrhosis and 97.5% (2010/2061) without cirrhosis. PK analysis demonstrated a 2.2-fold increase in glecaprevir exposure, but not pibrentasvir exposure, in patients with compensated cirrhosis. CONCLUSIONS: G/P was safe and efficacious in patients with compensated liver disease, including those with CKD 4/5.

Resistance characterization of hepatitis C virus genotype 2 from Japanese patients treated with ombitasvir and paritaprevir/ritonavir.

Treatment of HCV genotype (GT) 2-infected Japanese patients with paritaprevir (NS3/4A inhibitor boosted with ritonavir) and ombitasvir (NS5A inhibitor) without ribavirin for 12 weeks in the phase 2 study M12-536, and with ribavirin for 16 weeks in phase 3 study GIFT II resulted in SVR rates of 72.2% to 91.5%. Overall, 11 out of 125 patients with GT2a and 37 out of 79 patients with GT2b infection experienced virologic failure. The prevalence of baseline polymorphisms in NS3 and NS5A and their the impact on treatment outcome, as well as the development of viral resistance in GT2-infected patients experiencing virologic failure were evaluated by HCV NS3 and NS5A population and clonal sequence analyses. Baseline polymorphisms in NS3 that confer resistance to paritaprevir were rare in both GT2a- and GT2b-infected patients, while baseline polymorphisms in NS5A that confer resistance to ombitasvir were detected in 11.2% and 14.1% of the GT2a- and GT2b-infected patients, respectively. There was no significant impact of baseline polymorphisms on treatment outcome in Japanese patients. The most common treatment-emergent substitutions at the time of virologic failure occurred at amino acid positions 168 in NS3 and 28 in NS5A in both GT2a- and GT2b-infected patients. Although there was a higher rate of virologic failure in patients with GT2b infection, the resistance analyses presented in this report support the conclusion that testing for baseline resistance-associated polymorphisms is not warranted for HCV GT2-infected patients treated with a regimen of ombitasvir/paritaprevir/ritonavir + ribavirin for 16 weeks.

Randomized Phase 3 Trial of Ombitasvir/Paritaprevir/Ritonavir and Ribavirin for Hepatitis C Virus Genotype 2-Infected Japanese Patients.

INTRODUCTION: In Japan, hepatitis C virus (HCV) genotype (GT) 2 accounts for approximately 32% of HCV infections. Limited treatment options exist in Japan for HCV GT2-infected patients. GIFT-II was a phase 3, randomized, open-label study evaluating the efficacy and safety of 16- and 12-week regimens of co-formulated ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (r) plus ribavirin (RBV) in Japanese adults with HCV GT2 infection. METHODS: Patients were randomized in a 1:1 ratio to once-daily, co-formulated OBV/PTV/r (25/150/100 mg) with weight-based RBV for 16 or 12 weeks. The primary efficacy endpoint was the sustained virologic response at 12 weeks post-treatment (SVR12) rate in the primary efficacy population of non-cirrhotic treatment-naive patients. RESULTS: A total of 171 patients were randomized to OBV/PTV/r + RBV. In the primary efficacy population, SVR12 rates were 91.5% (43/47; 95% confidence interval 83.5-99.5%) and 75.0% (36/48; 95% confidence interval 62.8-87.2%) in the 16-week arm and 12-week arm, respectively. No patient in the 16-week arm relapsed by post-treatment week 12. Among non-cirrhotic treatment-experienced patients, the overall SVR rate in the 16-week arm was 75.8% (25/33) and was highest [93.8% (15/16)] among those who had relapsed after previous interferon-based therapy. SVR12 rates were consistently higher in patients with HCV GT2a infection versus HCV GT2b infection [16-week treatment arm: 93.9% (31/33) versus 85.7% (12/14) and 93.8% (15/16) versus 56.3% (9/16) among non-cirrhotic treatment-naive and treatment-experienced patients, respectively]. No patient discontinued treatment because of an adverse event. The most common adverse events were anemia, increased blood bilirubin, and nasopharyngitis. CONCLUSIONS: OBV/PTV/r + RBV for 16 weeks resulted in high SVR12 rates in non-cirrhotic Japanese patients infected with HCV GT2 who were treatment-naive or who had relapsed after an interferon-based therapy. Higher SVR12 rates were observed among patients with HCV GT2a infection versus those with GT2b infection. This regimen demonstrated a favorable safety profile.

Analysis of Hepatitis C Virus Genotype 1b Resistance Variants in Japanese Patients Treated with Paritaprevir-Ritonavir and Ombitasvir.

Treatment of HCV genotype 1b (GT1b)-infected Japanese patients with paritaprevir (NS3/4A inhibitor boosted with ritonavir) and ombitasvir (NS5A inhibitor) in studies M12-536 and GIFT-I demonstrated high sustained virologic response (SVR) rates. The virologic failure rate was 3% (13/436) across the two studies. Analyses were conducted to evaluate the impact of baseline resistance-associated variants (RAVs) on treatment outcome and the emergence and persistence of RAVs in patients experiencing virologic failure. Baseline paritaprevir resistance-conferring variants in NS3 were infrequent, while Y93H in NS5A was the most prevalent ombitasvir resistance-conferring variant at baseline. A comparison of baseline prevalence of polymorphisms in Japanese and western patients showed that Q80L and S122G in NS3 and L28M, R30Q, and Y93H in NS5A were significantly more prevalent in Japanese patients. In the GIFT-I study, the prevalence of Y93H in NS5A varied between 13% and 21% depending on the deep-sequencing detection threshold. Among patients with Y93H comprising <1%, 1 to 40%, or >40% of their preexisting viral population, the 24-week SVR (SVR24) rates were >99% (276/277), 93% (38/41), and 76% (25/33), respectively, indicating that the prevalence of Y93H within a patient's viral population is a good predictor of treatment response. The predominant RAVs at the time of virologic failure were D168A/V in NS3 and Y93H alone or in combination with other variants in NS5A. While levels of NS3 RAVs declined over time, NS5A RAVs persisted through posttreatment week 48. Results from these analyses are informative in understanding the resistance profile of an ombitasvir- plus paritaprevir/ritonavir-based regimen in Japanese GT1b-infected patients.

Randomized phase 3 trial of ombitasvir/paritaprevir/ritonavir for hepatitis C virus genotype 1b-infected Japanese patients with or without cirrhosis.

UNLABELLED: GIFT-I is a phase 3 trial evaluating the efficacy and safety of a 12-week regimen of coformulated ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (r) for treatment of Japanese hepatitis C virus genotype 1b-infected patients. It consists of a double-blind, placebo-controlled substudy of patients without cirrhosis and an open-label substudy of patients with compensated cirrhosis. Patients without cirrhosis were randomized 2:1 to once-daily OBV/PTV/r (25 mg/150 mg/100 mg; group A) or placebo (group B). Patients with cirrhosis received open-label OBV/PTV/r (group C). The primary efficacy endpoint was the rate of sustained virological response 12 weeks posttreatment in interferon-eligible, treatment-naive patients without cirrhosis and hepatitis C virus RNA ≥100,000 IU/mL in group A. A total of 321 patients without cirrhosis were randomized and dosed with double-blind study drug (106 received double-blind placebo and later received open-label OBV/PTV/r), and 42 patients with cirrhosis were enrolled and dosed with open-label OBV/PTV/r. In the primary efficacy population, the rate of sustained virological response 12 weeks posttreatment was 94.6% (106/112, 95% confidence interval 90.5-98.8). Sustained virological response 12 weeks posttreatment rates were 94.9% (204/215) in group A, 98.1% (104/106) in group B (open-label), and 90.5% (38/42) in group C. Overall, virological failure occurred in 3.0% (11/363) of patients who received OBV/PTV/r. The rate of discontinuation due to adverse events was 0%-2.4% in the three patient groups receiving OBV/PTV/r. The most frequent adverse event in patients in any group was nasopharyngitis. CONCLUSION: In this broad hepatitis C virus genotype 1b-infected Japanese patient population with or without cirrhosis, treatment with OBV/PTV/r for 12 weeks was highly effective and demonstrated a favorable safety profile.

Randomized trial of interferon- and ribavirin-free ombitasvir/paritaprevir/ritonavir in treatment-experienced hepatitis C virus-infected patients.

UNLABELLED: Approximately 2 million Japanese individuals are infected with hepatitis C virus and are at risk for cirrhosis, end-stage liver disease, and hepatocellular carcinoma. Patients in whom interferon (IFN)/ribavirin (RBV) therapy has failed remain at risk as effective therapeutic options are limited. This phase 2, randomized, open-label study evaluated an IFN- and RBV-free regimen of once-daily ombitasvir (ABT-267), an NS5A inhibitor, plus paritaprevir (ABT-450), an NS3/4A protease inhibitor dosed with ritonavir (paritaprevir/ritonavir), in pegylated IFN/RBV treatment-experienced Japanese patients with hepatitis C virus subtype 1b or genotype 2 infection. Patients without cirrhosis (aged 18-75 years) with subtype 1b infection received ombitasvir 25 mg plus paritaprevir/ritonavir 100/100 mg or 150/100 mg for 12 or 24 weeks; patients with genotype 2 infection received ombitasvir 25 mg plus paritaprevir/ritonavir 100/100 mg or 150/100 mg for 12 weeks. Sustained virologic response (SVR) at posttreatment week 24 (SVR24 ) was the primary endpoint. Adverse events were collected throughout the study. One hundred ten patients received ≥1 dose of study medication. In the subtype 1b cohort, SVR24 rates were high (88.9%-100%) regardless of paritaprevir dose or treatment duration. In the genotype 2 cohort, SVR24 rates were 57.9% and 72.2% with 100 mg and 150 mg of paritaprevir, respectively. The SVR24 rate was higher in patients with subtype 2a (90%) than 2b (27%). Concordance between SVR12 and SVR24 was 100%. The most common adverse events overall were nasopharyngitis (29%) and headache (14%). CONCLUSION: In this difficult-to-treat population of patients in whom prior pegylated IFN/RBV had failed, ombitasvir/paritaprevir/ritonavir demonstrated potent antiviral activity with a favorable safety profile among Japanese patients with hepatitis C virus genotype 1b or 2a infection.

In vitro and in vivo antiviral activity and resistance profile of ombitasvir, an inhibitor of hepatitis C virus NS5A.

Ombitasvir (ABT-267) is a hepatitis C virus (HCV) NS5A inhibitor with picomolar potency, pan-genotypic activity, and 50% effective concentrations (EC50s) of 0.82 to 19.3 pM against HCV genotypes 1 to 5 and 366 pM against genotype 6a. Ombitasvir retained these levels of potency against a panel of 69 genotype 1 to 6 chimeric replicons containing the NS5A gene derived from HCV-infected patients, despite the existence of natural sequence diversity within NS5A. In vitro resistance selection identified variants that conferred resistance to ombitasvir in the HCV NS5A gene at amino acid positions 28, 30, 31, 58, and 93 in genotypes 1 to 6. Ombitasvir was evaluated in vivo in a 3-day monotherapy study in 12 HCV genotype 1-infected patients at 5, 25, 50, or 200 mg dosed once daily. All patients in the study were HCV genotype 1a infected and were without preexisting resistant variants at baseline as determined by clonal sequencing. Decreases in HCV RNA up to 3.1 log10 IU/ml were observed. Resistance-associated variants at position 28, 30, or 93 in NS5A were detected in patient samples 48 hours after the first dose. Clonal sequencing analysis indicated that wild-type virus was largely suppressed by ombitasvir during 3-day monotherapy, and at doses higher than 5 mg, resistant variant M28V was also suppressed. Ombitasvir was well tolerated at all doses, and there were no serious or severe adverse events. These data support clinical development of ombitasvir in combination with inhibitors targeting HCV NS3/4A protease (ABT-450 with ritonavir) and HCV NS5B polymerase (ABT-333, dasabuvir) for the treatment of chronic HCV genotype 1 infection. (Study M12-116 is registered at ClinicalTrials.gov under registration no. NCT01181427.).

An interferon-free antiviral regimen for HCV after liver transplantation.

BACKGROUND: Hepatitis C virus (HCV) infection is the leading indication for liver transplantation worldwide, and interferon-containing regimens are associated with low response rates owing to treatment-limiting toxic effects in immunosuppressed liver-transplant recipients. We evaluated the interferon-free regimen of the NS5A inhibitor ombitasvir coformulated with the ritonavir-boosted protease inhibitor ABT-450 (ABT-450/r), the nonnucleoside NS5B polymerase inhibitor dasabuvir, and ribavirin in liver-transplant recipients with recurrent HCV genotype 1 infection. METHODS: We enrolled 34 liver-transplant recipients with no fibrosis or mild fibrosis, who received ombitasvir-ABT-450/r (at a once-daily dose of 25 mg of ombitasvir, 150 mg of ABT-450, and 100 mg of ritonavir), dasabuvir (250 mg twice daily), and ribavirin for 24 weeks. Selection of the initial ribavirin dose and subsequent dose modifications for anemia were at the investigator's discretion. The primary efficacy end point was a sustained virologic response 12 weeks after the end of treatment. RESULTS: Of the 34 study participants, 33 had a sustained virologic response at post-treatment weeks 12 and 24, for a rate of 97% (95% confidence interval, 85 to 100). The most common adverse events were fatigue, headache, and cough. Five patients (15%) required erythropoietin; no patient required blood transfusion. One patient discontinued the study drugs owing to adverse events after week 18 but had a sustained virologic response. Blood levels of calcineurin inhibitors were monitored, and dosages were modified to maintain therapeutic levels; no episode of graft rejection was observed during the study. CONCLUSIONS: Treatment with the multitargeted regimen of ombitasvir-ABT-450/r and dasabuvir with ribavirin was associated with a low rate of serious adverse events and a high rate of sustained virologic response among liver-transplant recipients with recurrent HCV genotype 1 infection, a historically difficult-to-treat population.

A randomized, double-blind study of fenofibric acid plus rosuvastatin compared with rosuvastatin alone in stage 3 chronic kidney disease.

BACKGROUND: Patients with chronic kidney disease (CKD) often have mixed dyslipidemia and high cardiovascular disease risk. Although statins reduce LDL-C, adding a fibrate may further improve lipid parameters. OBJECTIVE: This multicenter, randomized study evaluated the short-term efficacy and safety profile of fenofibric acid (FA) + rosuvastatin (R) combination therapy for improving lipid parameters in patients with stage 3 CKD and mixed dyslipidemia. The study also assessed estimated glomerular filtration rate after study drug washout. METHODS: Patients received FA 45 mg + R (5 mg for 8 weeks, then 10 mg for 8 additional weeks) or R monotherapy (5 mg for 8 weeks, then 10 mg for 8 additional weeks), followed by an 8-week washout period. Primary and secondary end points were percent changes in triglycerides and HDL-C, respectively, from baseline to week 8. RESULTS: FA 45 mg + R 5 mg, compared with R 5 mg, resulted in significant improvements in triglycerides (median % changes: week 8, -38.0% vs -22.4%, P < 0.001; week 16, -42.6% vs -29.7%, P < 0.001) and HDL-C (mean % changes: week 8, 16.9% vs 7.8%, P < 0.001; week 16, 17.3% vs 8.9%, P < 0.001). Adverse event rates were similar between groups (70.7% with FA + R vs 68.6% with R). Mean serum creatinine level at baseline was 1.36 mg/dL in the FA + R group and 1.38 mg/dL in the R group. The final treatment serum creatinine value, defined as the last nonmissing postbaseline value collected within 30 days after the last dose of study drug, was 1.52 mg/dL with FA + R (vs 1.41 mg/dL with R; P < 0.001), which then decreased to 1.39 mg/dL after the 8-week washout (vs 1.42 mg/dL with R). CONCLUSIONS: The data suggest that, after 16 weeks of therapy, FA + R has an acceptable safety profile and improved TG and HDL-C efficacy versus R. FA + R combination therapy may thus further improve lipid parameters in patients with stage 3 CKD and mixed dyslipidemia. ClinicalTrials.gov identifier: NCT00680017.

Study design, rationale, and baseline characteristics: evaluation of fenofibric acid on carotid intima-media thickness in patients with type IIb dyslipidemia with residual risk in addition to atorvastatin therapy (FIRST) trial.

PURPOSE: Elevated triglycerides (TG) and low high-density lipoprotein cholesterol (HDL-C) levels contribute to cardiovascular disease risk and can be effectively treated with fenofibric acid. A trial is under way to evaluate the effect of once-daily fenofibric acid or placebo on carotid intima-media thickness (CIMT) progression in patients with controlled low-density lipoprotein cholesterol (LDL-C) levels achieved through atorvastatin treatment, but with high TG and low HDL-C levels. METHODS: In this multicenter, double-blind study, 682 patients were randomized to once-daily delayed-release capsules of choline fenofibrate 135 mg (fenofibric acid [Trilipix(®); Abbott, North Chicago, IL]) or placebo plus atorvastatin treatment after a 2- to 10-week diet and atorvastatin run-in period. Key inclusion criteria included age ≥45 years; posterior-wall common CIMT ≥0.7 mm on at least one side at baseline; fasting results of TG ≥150 mg/dL, and HDL-C ≤45 mg/dL for men or HDL-C ≤55 mg/dL for women at screening while receiving atorvastatin; controlled LDL-C; and known coronary heart disease (CHD) or a CHD risk equivalent. The primary efficacy variable is the rate of change from baseline through week 104 in the mean posterior-wall intima-media thickness of the common carotid arteries (composite value of left and right sides). CONCLUSIONS: This trial is the first to examine the effect of fenofibric acid on CIMT and the first CIMT trial to select patients with controlled LDL-C and elevated TG and low HDL-C as inclusion criteria. Also, this trial will prospectively evaluate the effect of treatment on LDL particles and address shortcomings of previous CIMT trials.

One-year efficacy and safety of rosuvastatin + fenofibric acid combination therapy in patients with mixed dyslipidemia: evaluation of dose response.

BACKGROUND: Statins are the standard-of-care therapy for reducing low-density lipoprotein cholesterol (LDL-C) levels; however, combination with other lipid-modifying agents may be necessary to normalize lipid profiles in patients with mixed dyslipidemia who, in addition to high LDL-C, also have high triglycerides (TG) and low levels of high-density lipoprotein cholesterol (HDL-C). OBJECTIVE: This study aimed to evaluate the 1-year efficacy and safety of rosuvastatin in combination with fenofibric acid in a subgroup of patients treated for 12 weeks with rosuvastatin 10 mg + fenofibric acid 135 mg and subsequently treated for up to 52 weeks with rosuvastatin 20 mg + fenofibric acid 135 mg. METHODS: The efficacy and safety of combination therapy with rosuvastatin + fenofibric acid were demonstrated in a 12-week controlled study (NCT00300482) of patients with mixed dyslipidemia who were randomized to rosuvastatin 10, 20, or 40 mg, fenofibric acid 135 mg, or rosuvastatin 10 or 20 mg + fenofibric acid 135 mg. All patients who completed the controlled study were eligible to enroll in a subsequent 52-week open-label extension study (NCT00300430) and received rosuvastatin 20 mg + fenofibric acid 135 mg. The present post hoc analysis evaluated patients who were treated with rosuvastatin 10 mg + fenofibric acid 135 mg in the controlled study and received rosuvastatin 20 mg + fenofibric acid 135 mg in the open-label extension study. The study was carried out at investigative sites in the US (including Puerto Rico) and Canada. Patients included in the study were men and women ≥18 years of age with mixed dyslipidemia, defined as TG ≥150 mg/dL, LDL-C ≥130 mg/dL, and HDL-C <40/50 mg/dL for men/women (at screening in the controlled trial). Efficacy variables included mean percentage changes in LDL-C, HDL-C, non-HDL-C, and apolipoprotein B (ApoB), and median percentage changes in TG and high-sensitivity C-reactive protein (hsCRP) from baseline (i.e. start of the open-label extension after 12 weeks of treatment with rosuvastatin 10 mg + fenofibric acid 135 mg) to incremental time points up to 52 weeks in the extension study, and the proportion of patients achieving individual and combined goals for LDL-C and non-HDL-C. Adverse events (AEs) and clinical laboratory values were also assessed. RESULTS: Of the 261 patients initially randomized to rosuvastatin 10 mg + fenofibric acid 135 mg, 220 completed the controlled study and 187 continued treatment with rosuvastatin 20 mg + fenofibric acid 135 mg in the extension study. Increasing the rosuvastatin dose from 10 mg to 20 mg in combination with fenofibric acid 135 mg for up to 52 weeks resulted in significant (p ≤ 0.005 for all comparisons) mean percentage changes from baseline in LDL-C (-9.5%), non-HDL-C (-6.0%), ApoB (-8.5%), and HDL-C (3.6%), while median TG levels remained largely unchanged (0.8%, p = 0.055) at the week 52 visit. Greater percentages of patients achieved their risk-stratified lipid goals at week 52 compared with baseline for LDL-C (89% vs 84%), non-HDL-C (50% vs 25%), and both LDL-C and non-HDL-C (50% vs 19%). Combination therapy was generally well tolerated. The incidence of muscle-, hepatic-, and renal-related AEs and laboratory values were within the expected range. CONCLUSION: This study demonstrates that 1-year therapy with rosuvastatin + fenofibric acid is well tolerated and that increasing the rosuvastatin dose from 10 mg to 20 mg in the combination results in additional beneficial effects on key lipid parameters in patients with mixed dyslipidemia.

Attainment of goal/desirable lipid levels in patients with mixed dyslipidemia after 12 weeks of treatment with fenofibric acid and rosuvastatin combination therapy: a pooled analysis of controlled studies.

BACKGROUND: Goal/desirable lipid levels are underachieved in patients with mixed dyslipidemia. These patients may have substantial residual risk of cardiovascular disease even while receiving optimal LDL-C-lowering therapy and may require additional therapy to improve multiple lipid/lipoprotein levels. OBJECTIVE: To evaluate attainment of goal/desirable levels of lipids/lipoproteins after 12-week treatment with combination rosuvastatin + fenofibric acid versus rosuvastatin monotherapy. METHODS: This was a post hoc analysis of patients with mixed dyslipidemia who enrolled in one of two randomized controlled trials, and were treated (N = 2066) with rosuvastatin (5, 10, or 20 mg), fenofibric acid 135 mg, or rosuvastatin + fenofibric acid for 12 weeks. Data were pooled across doses of rosuvastatin as monotherapy and combination therapy. RESULTS: Compared with rosuvastatin monotherapy, combination therapy had comparable effects in achieving risk-stratified LDL-C goals; however, measures of total atherogenic burden were improved because significantly greater percentages of patients attained non-HDL-C goal in high- (62.9% vs 50.4%, P = .006) and moderate-risk groups (87.6% vs 80.4%, P = .016) and apolipoprotein B (ApoB) <90 mg/dL in high-risk group (59.8% vs 43.8%, P < .001). In the overall population, more patients treated with the combination therapy achieved desirable levels of HDL-C >40/50 mg/dL in men/women (P < .001), triglycerides <150 mg/dL (P < .001), and ApoB <90 mg/dL (P < .001), compared with rosuvastatin monotherapy. Furthermore, combination therapy resulted in significantly greater percentages of patients achieving simultaneous specified levels of LDL-C + non-HDL-C (P < .015); LDL-C + HDL-C + TG (P < .001); and LDL-C + HDL-C + triglycerides + non-HDL-C + ApoB (P < .001), compared with rosuvastatin monotherapy. CONCLUSION: Rosuvastatin + fenofibric acid may be more efficacious than rosuvastatin alone in patients with mixed dyslipidemia.

Effects of combination therapy with rosuvastatin and fenofibric acid in patients with mixed dyslipidemia and high-sensitivity C-reactive protein (≥ 2 mg/L). cmb@bcm.tmc.edu.

BACKGROUND: Elevated levels of high-sensitivity C-reactive protein (hsCRP) correlate with an increased risk for cardiovascular events. Combination therapy with a statin and a fibrate may be more effective than statin monotherapy for reducing hsCRP, especially in patients with mixed dyslipidemia. OBJECTIVE: To characterize the treatment effects of rosuvastatin and fenofibric acid combination therapy compared with individual monotherapies in mixed dyslipidemic patients with baseline hsCRP ≥2 mg/L versus <2 mg/L and to determine the effects of long-term treatment with rosuvastatin and fenofibric acid combination therapy on hsCRP and other lipids for patients with hsCRP ≥2 mg/L after treatment with rosuvastatin monotherapy. METHODS: Data for the post hoc analysis were derived from two 12-week controlled studies and a 52-week extension study. Patients were treated with fenofibric acid 135 mg; rosuvastatin 5, 10, 20, or 40 mg; or rosuvastatin 5, 10, or 20 mg and fenofibric acid 135 mg in the controlled studies; and with rosuvastatin 20 mg and fenofibric acid 135 mg in the extension study. RESULTS: In this analysis, 65% (1416/2182) of patients had pretreatment baseline hsCRP ≥2 mg/L. Among all treatment groups, larger decreases in hsCRP were observed in patients with greater baseline hsCRP; however, improvements in other lipids/apolipoprotein were comparable between the baseline hsCRP categories. Among patients with high hsCRP (≥2 mg/L) remaining after 12 weeks of rosuvastatin 10, 20, or 40 mg monotherapy, hsCRP was reduced by ∼36% after switching to rosuvastatin 20 mg and fenofibric acid 135 mg for up to 52 weeks, and ∼36% of patients shifted from hsCRP ≥2 mg/L to <2 mg/L. CONCLUSIONS: Combination therapy with rosuvastatin and fenofibric acid may be effective for improving the inflammatory biomarker, hsCRP as well as other lipid abnormalities in patients with mixed dyslipidemia and high hsCRP.

Long-term efficacy of adding fenofibric acid to moderate-dose statin therapy in patients with persistent elevated triglycerides.

OBJECTIVE: The objective of this study was to evaluate the long-term efficacy of adding fenofibric acid to moderate-dose statin therapy in patients at goal for low-density lipoprotein cholesterol (LDL-C) but with persistent hypertriglyceridemia. METHODS: This is a post hoc analysis of a subset of patients (N = 92) with mixed dyslipidemia treated with moderate-dose statin (rosuvastatin 20 mg, simvastatin 40 mg, or atorvastatin 40 mg) for 12 weeks in three controlled trials who had achieved LDL-C <100 mg/dL but whose triglycerides remained >200 mg/dL, and had fenofibric acid 135 mg added to the moderate-dose statin in a 52-week open-label extension study. Lipid and apolipoprotein (Apo) values and the proportion of patients meeting individual and combined treatment targets with combination therapy were determined at scheduled visits during the 52-week study and compared with baseline (start of extension study). RESULTS: Addition of fenofibric acid to moderate-dose statin for 52 weeks resulted in significant (P < 0.001) improvements in non-high-density lipoprotein cholesterol (non-HDL-C; -9.0%), ApoB (-9.8%), HDL-C (14.9%), and triglycerides (-37.6%) compared with baseline. At final visit, greater proportions of patients achieved optimal levels of individual parameters as well as combined targets of LDL-C + non-HDL-C (60.0% vs 52.2%), LDL-C + non-HDL-C + ApoB (53.3% vs 37.8%, P = 0.007), and LDL-C + non-HDL-C + ApoB + HDL-C + triglycerides (25.6% vs 0.0%) than at baseline. CONCLUSIONS: The addition of fenofibric acid to moderate-dose statin in patients whose LDL-C was optimal but whose triglycerides remained >200 mg/dL led to additional improvements in non-HDL-C, ApoB, HDL-C, and triglycerides that resulted in greater proportions of patients attaining optimal levels of the individual parameters as well as simultaneously achieving optimal levels of these parameters and LDL-C.

Evaluating optimal lipid levels in patients with mixed dyslipidemia following short- and long-term treatment with fenofibric acid and statin combination therapy: a post hoc analysis.

OBJECTIVE: To evaluate the achievement of individual and combined lipid and lipoprotein/biomarker targets as specified by treatment guidelines with the combination of fenofibric acid and statin therapy in patients with mixed dyslipidemia. METHODS: Data for the post hoc analyses were derived from three 12-week controlled studies and a 52-week extension study. Patients were treated with fenofibric acid 135 mg; low-, moderate-, or high-dose statin (rosuvastatin 10, 20, or 40 mg; atorvastatin 20, 40, or 80 mg; or simvastatin 20, 40, or 80 mg); or fenofibric acid + low- or moderate-dose statin in the controlled studies; and with fenofibric acid + moderate-dose statin in the extension study. Achievement of risk-stratified low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B (ApoB) targets; and optimal levels of ApoB <90 mg/dL, HDL-C >40/50 mg/dL in men/women, triglycerides (TG) < 150 mg/dL, and high-sensitivity C-reactive protein <2 mg/L were assessed. RESULTS: In the controlled studies, significantly lower percentage of high-risk patients treated with fenofibric acid + moderate-dose statin, and significantly higher percentage of high-risk patients treated with fenofibric acid + low-dose statin, compared with corresponding-dose statin monotherapies, achieved their LDL-C (51.3% vs. 72.9%, p < 0.001) and non-HDL-C targets (53% vs. 38%, p = 0.02), respectively. Among all patients, optimal levels of ApoB, HDL-C, TG, and the combined target of LDL-C + non-HDL-C + ApoB + HDL-C + TG were achieved by higher percentage of patients treated with fenofibric acid + low- and moderate-dose statin versus corresponding dose-statin monotherapies (p ≤ 0.04 for all comparisons). In the extension study, significantly (p < 0.001 for all comparisons) higher percentage of patients had achieved individual and combined targets at final visit, compared with baseline. CONCLUSIONS: In patients with mixed dyslipidemia, short-term treatment with the combination of fenofibric acid and low- or moderate-dose statin resulted in comparable or more patients achieving individual targets of non-HDL-C, ApoB, HDL-C, and TG, and combined targets for these parameters and LDL-C, compared with corresponding-dose statin monotherapy. In the long-term study, the proportion meeting these targets was significant, compared with baseline. Limitations include the post hoc nature of the analysis, and the fact that all patients had mixed dyslipidemia and majority were white, which limits generalization to other populations.

Efficacy of fenofibric acid plus statins on multiple lipid parameters and its safety in women with mixed dyslipidemia.

The combination of fibrate and statin therapies may be a treatment option for women with multiple lipid abnormalities. We, therefore, initiated the present safety and efficacy analysis to address the paucity of such data in women with mixed dyslipidemia. A total of 1,393 women with mixed dyslipidemia (low-density lipoprotein [LDL] cholesterol ≥ 130 mg/dl, triglycerides [TG] ≥ 150 mg/dl, high-density lipoprotein [HDL] cholesterol <50 mg/dl), who had enrolled in any 1 of 3 randomized clinical trials, were evaluated. The eligible women were randomized to receive fenofibric acid plus a low- or moderate-dose statin (combination treatment); or low-, moderate-, or high-dose statin monotherapy; or fenofibric acid monotherapy. With low-dose combination treatment, the baseline HDL cholesterol level increased 20% and TG decreased 46% compared to an 8% HDL cholesterol increase and 20% TG decrease with low-dose statins alone. With the moderate-dose combination, the baseline HDL cholesterol increased 21% and TG decreased 44% compared to an 8% HDL cholesterol increase and 26% TG decrease with moderate-dose statins alone. The reduction in baseline LDL cholesterol with low-dose and moderate-dose combinations (37% and 39%, respectively) was comparable to the reduction with corresponding-dose statins (36% and 43%, respectively). High-dose statins decreased the baseline LDL cholesterol 47%; however, the increase in HDL cholesterol (9%) and decrease in TG (25%) were similar to the changes observed with lower doses of statins. The safety profiles of the combinations were comparable to those of the component therapies. In conclusion, these data suggest that a combination of fenofibric acid and a statin could be considered safe and efficacious for treating women with mixed dyslipidemia.

Achievement of lipid targets with the combination of rosuvastatin and fenofibric Acid in patients with type 2 diabetes mellitus.

OBJECTIVE: The objective of this study was to assess the proportion of patients with type 2 diabetes mellitus (T2DM) attaining individual and combined targets of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), non-HDL-C, and apolipoprotein B (ApoB) after treatment with rosuvastatin (R) + fenofibric acid (FA) compared with corresponding-dose R monotherapy. METHODS: This post hoc analysis evaluated data from the T2DM subset of patients with mixed dyslipidemia (LDL-C ≥130 mg/dL, HDL-C <40/50 mg/dL in men/women, and TG ≥150 mg/dL) from 2 randomized studies. Patients included in the analysis (N = 456) were treated with R (5, 10, or 20 mg), FA 135 mg, or R (5, 10, or 20 mg) + FA 135 mg for 12 weeks. Attainment of LDL-C <100 mg/dL, HDL-C >40/50 mg/dL in men/women, TG <150 mg/dL, non-HDL-C <130 mg/dL, ApoB <90 mg/dL, and the combined targets of these parameters was assessed. RESULTS: Treatment with R + FA resulted in a significantly higher proportion of patients achieving optimal levels of HDL-C (46.8% vs. 20.8%, P = 0.009 for R 10 mg + FA), TG (60.0% vs. 34.0%, P = 0.02 for R 10 mg + FA; 54.0% vs. 26.4%, P = 0.005 for R 20 mg + FA), non-HDL-C (55.1% vs. 36.4%, P = 0.04 for R 5 mg + FA), ApoB (58.0% vs. 36.4%, P = 0.02 for R 5 mg + FA); and the combined targets of LDL-C, HDL-C, and TG (28.3% vs. 8.3%, P = 0.02 for R 10 mg + FA) and all 5 parameters (26.1% vs. 8.3%, P = 0.03 for R 10 mg + FA) than corresponding-dose R monotherapies. CONCLUSIONS: A significantly greater proportion of T2DM patients achieved individual and combined lipid targets when treated with the combination of R + FA than corresponding-dose R monotherapies.

Combination rosuvastatin plus fenofibric acid in a cohort of patients 65 years or older with mixed dyslipidemia: subanalysis of two randomized, controlled studies.

BACKGROUND: Coronary heart disease risk increases with advancing age and is further increased in patients with mixed dyslipidemia, characterized by elevated low-density lipoprotein cholesterol (LDL-C), low high-density lipoprotein cholesterol (HDL-C), and high triglycerides (TG). Combination lipid therapy is an option; however, efficacy and safety data among elderly patients are lacking. HYPOTHESIS: The combination of rosuvastatin and fenofibric acid (R + FA) results in more comprehensive lipid improvements than corresponding-dose monotherapies, without additional safety concerns, in elderly patients with mixed dyslipidemia. METHODS: This post-hoc analysis evaluated data from patients age ≥ 65 years (n = 401) with mixed dyslipidemia (LDL-C ≥ 130 mg/dL, HDL-C < 40 mg/dL [men] or < 50 mg/dL [women], and TG ≥ 150 mg/dL) in 2 randomized studies. Patients included in this analysis received either monotherapy (as R 5, 10, or 20 mg or FA 135 mg), or combination therapy with R (5, 10, or 20 mg) + FA 135 mg, for 12 weeks. Data were pooled and analyzed, and mean/median percent changes in multiple lipid parameters and biomarkers were compared. RESULTS: Combination therapy decreased LDL-C by 31.8%-47.2% vs 10.6% with FA monotherapy (P < 0.001). Combination therapy also increased HDL-C by 21.9%-27.0% vs 5.9%-9.9% with R monotherapy (P < 0.001), and decreased TG by 48.3%-53.5% vs 20.7%-32.8% with R monotherapy (P < 0.001). In general, safety profiles were consistent between combination therapy and individual monotherapies. CONCLUSIONS: In these elderly patients with mixed dyslipidemia, R 5, 10, or 20 mg in combination with FA 135 mg improved the overall lipid profile, without new or unexpected safety issues.

Efficacy and safety of rosuvastatin 5 mg in combination with fenofibric acid 135 mg in patients with mixed dyslipidemia - a phase 3 study.

BACKGROUND: Patients with mixed dyslipidemia characterized by elevated low-density lipoprotein cholesterol (LDL-C), elevated triglycerides (TG), and reduced high-density lipoprotein cholesterol (HDL-C) often require combination therapy to improve multiple lipid and nonlipid parameters. This phase 3, multicenter, randomized, double-blind study evaluated the efficacy and safety of rosuvastatin 5 mg coadministered with fenofibric acid 135 mg in patients with mixed dyslipidemia. METHODS: A total of 760 patients with TG ≥ 150 mg/dL, HDL-C <40 mg/dL (<50 mg/dL for women), and LDL-C ≥ 130 mg/dL were randomized for a 12-week treatment period to rosuvastatin 5 mg, fenofibric acid 135 mg, or rosuvastatin 5 mg + fenofibric acid 135 mg. The primary efficacy comparisons were mean percentage changes in HDL-C and TG (rosuvastatin + fenofibric acid vs. rosuvastatin monotherapy), and LDL-C (rosuvastatin + fenofibric acid vs. fenofibric acid monotherapy). RESULTS: Treatment with rosuvastatin + fenofibric acid resulted in statistically significant greater improvements in HDL-C (23.0% vs. 12.4%; P < 0.001) and TG (-40.3% vs. -17.5%; P < 0.001), compared with rosuvastatin monotherapy; and LDL-C (-28.7% vs. -4.1%; P < 0.001), compared with fenofibric acid monotherapy. All secondary efficacy variables improved with combination therapy. Combination therapy was generally well tolerated with a safety profile consistent with individual monotherapies. No unexpected muscle, hepatic, or renal safety signals were identified with combination therapy versus individual monotherapies. CONCLUSION: In conclusion, rosuvastatin 5 mg + fenofibric acid 135 mg resulted in comprehensive improvements in the lipid profile of patients with mixed dyslipidemia without unanticipated adverse events.

Efficacy and safety of fenofibric acid in combination with atorvastatin and ezetimibe in patients with mixed dyslipidemia.

BACKGROUND: Statin and ezetimibe combination therapy may be insufficient to improve lipid and nonlipid parameters beyond low-density lipoprotein cholesterol (LDL-C) in patients with mixed dyslipidemia. METHODS: In this phase 3, multicenter, double-blind study, a total of 543 patients with triglycerides ≥150 mg/dL and <400 mg/dL, high-density lipoprotein cholesterol (HDL-C) <40 mg/dL (<50 mg/dL for women), and LDL-C ≥130 mg/dL were randomized to 12 weeks of treatment with fenofibric acid 135 mg (FA) or placebo, each coadministered with atorvastatin 40 mg + ezetimibe 10 mg (Atorva/Eze). RESULTS: Both treatment regimens lowered LDL-C by >50%; however, FA + Atorva/Eze resulted in significantly (P < .001) greater improvements in HDL-C (13.0% vs 4.2%), triglycerides (-57.3% vs -39.7%), non-HDL-C (-55.6% vs -51.0%), and apoprotein B (-49.1% vs -44.7%) compared with Atorva/Eze. Overall, adverse events were similar in the 2 treatment groups. No unexpected muscle, hepatic, or renal safety signals were identified with either treatment combination. CONCLUSIONS: In patients with mixed dyslipidemia, the combination of FA + Atorva/Eze significantly improved lipid and nonlipid parameters compared with Atorva/Eze and was generally well tolerated.
