SAN FRANCISCO, June 17, 2013 /PRNewswire/ -- Kowa Pharmaceuticals America, Inc. and Eli Lilly and Company (NYSE: LLY) announced results of a pre-specified safety analysis from theINTREPID(HIV-infected patieNts and TREatment with PItavastatin vs. pravastatin for Dyslipidemia)trial evaluating the effect of LIVALO® (pitavastatin) 4 mg compared with pravastatin 40 mg on changes in levels of blood glucose and glycated hemoglobin (HbA1c) in HIV-infected adults with dyslipidemia. INTREPID was a Phase 4, multicenter, 12-week randomized superiority study followed by a 40-week safety extension study (NCT01301066) comparing the lipid-lowering effects of pitavastatin 4 mg and pravastatin 40 mg in adults with HIV infection and dyslipidemia.1
The results of this pre-specified safety analysis, presented yesterday at the Endocrine Society's 95th Annual Meeting & Expo in San Francisco, CA, showed neutral effects of pitavastatin 4 mg and pravastatin 40 mg on fasting serum glucose (FSG) and HbA1c levels over 12 weeks.1
By week 12, the mean change in FSG for pitavastatin (n=109) was -0.1mg/dL and pravastatin (n=112) was 0.6 mg/dL, and the adjusted (least squares mean) change in FSG was 0.6 mg/dL for pitavastatin and 2.5 mg/dL for pravastatin with no significant differences in each treatment group (p=0.68 and 0.09, respectively). There was no significant difference between treatment groups (p=0.20).1
The mean change in HbA1c was -0.02% for pitavastatin (n=110) and -0.01% for pravastatin (n=113), and the adjusted (least squares mean) change in HbA1c was 0.04% for pitavastatin and 0.05% for pravastatin with no significant differences in each treatment group (p=0.27 and 0.09, respectively). There was no significant difference between treatment groups (p=0.58). A significantly greater decrease in LDL-C over 12 weeks was noted with pitavastatin 4 mg compared with pravastatin 40 mg where the primary endpoint of mean percent change was -31.1% and -20.9%, respectively (p<0.001), with a mean change in LDL-C of -49.4 mg/dL for pitavastatin 4 mg vs. -33.6 mg/dL for pravastatin 40 mg.1
Studies have shown that patients living with HIV infection have increased cardiovascular disease risk factors, including dyslipidemia and glucose abnormalities.2
"We are pleased with the results of this safety analysis that showed neutrality for the maximum dose of pitavastatin 4 mg on parameters of glucose metabolism, which are consistent with our previous findings in non-HIV-infected adult populations with dyslipidemia," said Dr. Craig Sponseller, Vice President of Medical Affairs at Kowa Pharmaceuticals America, Inc.
Study investigator, Dr. Judith Aberg, Director of Virology, Bellevue Hospital Center and Director, Division of Infectious Diseases and Immunology, NYU School of Medicine, said, "Based on treatment guidelines, statins are often the first line treatment for the management of dyslipidemia when therapeutic lifestyle changes are not effective in HIV-infected patients. These results may further physician education on statin use."
About the Study
In the 12-week, Phase 4, randomized (1:1), double-blind, double-dummy, active-controlled, parallel-group study, 252 patients were randomized to receive once-daily doses of pitavastatin 4 mg or pravastatin 40 mg. Only patients who took the study drug and had both baseline and week 12 values for FSG or HbA1c were included in these analyses. Mean changes from baseline to week 12 were compared between treatments using ANCOVA, with change in FSG/HbA1c as the dependent variable, and treatment, site and hepatitis B and C status as independent variables.1
LIVALO is a HMG-CoA reductase inhibitor indicated as an adjunctive therapy to diet to reduce elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (Apo B), triglycerides (TG), and to increase high-density lipoprotein cholesterol (HDL-C) in adult patients with primary hyperlipidemia or mixed dyslipidemia.
Limitations of Use:
- Doses of LIVALO greater than 4 mg once daily were associated with an increased risk for severe myopathy in premarketing clinical studies. Do not exceed 4 mg once daily dosing of LIVALO.
- The effect of LIVALO on cardiovascular morbidity and mortality has not been determined.
- LIVALO has not been studied in Fredrickson Type I, III, and V dyslipidemias.
In addition to being launched in the U.S. in June 2010, LIVALO has been approved in 33 other countries around the world as of May 2013.3
Primary Hyperlipidemia and Mixed Dyslipidemia
Primary hyperlipidemia is defined as an elevation of cholesterol, particularly "bad" cholesterol (LDL-C), triglycerides (TG), or both. Mixed dyslipidemia is usually characterized by an elevation of LDL-C, TG, and a decrease in the "good" cholesterol (HDL-C) in the blood.
IMPORTANT SAFETY INFORMATION FOR LIVALO® (pitavastatin) tablets
LIVALO is contraindicated in patients with a known hypersensitivity to product components, in patients with active liver disease (which may include unexplained persistent elevations in hepatic transaminase levels), in women who are pregnant or may become pregnant, in nursing mothers, or in co-administration with cyclosporine.
WARNINGS AND PRECAUTIONS
Skeletal Muscle Effects
Cases of myopathy and rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with HMG-CoA reductase inhibitors, including LIVALO. These risks can occur at any dose level, but increase in a dose-dependent manner.
- LIVALO should be prescribed with caution in patients with predisposing factors for myopathy
- The risk of skeletal muscle effects (e.g., myopathy, and rhabdomyolysis) increases in a dose-dependent manner with advanced age (>65 years), renal impairment, inadequately treated hypothyroidism, and in combination use with fibrates or lipid-modifying doses of niacin (>1 g/day)
- LIVALO should be administered with caution in patients with impaired renal function, in elderly patients, or when used concomitantly with fibrates or lipid-modifying doses of niacin
- Concomitant administration of LIVALO with gemfibrozil should be avoided
- LIVALO therapy should be discontinued if markedly elevated CK levels occur or myopathy is diagnosed or suspected. LIVALO therapy should also be temporarily withheld in any patient with an acute, serious condition suggestive of myopathy or predisposing to the development of renal failure secondary to rhabdomyolysis (e.g., sepsis; hypotension; dehydration; major surgery; trauma; severe metabolic, endocrine, and electrolyte disorders; or uncontrolled seizures)
- Advise patients to promptly report unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever, and to discontinue LIVALO if these signs or symptoms appear
- Cases of myopathy, including rhabdomyolysis, have been reported with HMG-CoA reductase inhibitors coadministered with colchicine, and caution should be exercised when prescribing LIVALO with colchicine
- There have been rare reports of immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, associated with statin use. IMNM is characterized by: proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; muscle biopsy showing necrotizing myopathy without significant inflammation; improvement with immunosuppressive agents. IMNM has not been reported with LIVALO therapy
- Advise patients to promptly report if muscle signs and symptoms persist after discontinuing LIVALO as this may be a sign of IMNM requiring immediate medical attention
Liver Enzyme Abnormalities
Increases in serum transaminases have been reported with HMG-CoA reductase inhibitors, including LIVALO.
- It is recommended that liver enzyme tests be performed before the initiation of LIVALO and if signs or symptoms of liver injury occur
- There have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins, including pitavastatin. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with LIVALO, promptly interrupt therapy. If an alternate etiology is not found do not restart LIVALO
- Advise patients to promptly report any symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine or jaundice
- LIVALO should be used with caution in patients who consume substantial quantities of alcohol and/or have a history of chronic liver disease
Increases in HbA1c and fasting serum glucose levels have been reported with HMG-CoA reductase inhibitors, including LIVALO.
In short-term controlled studies, the most frequent adverse reactions reported by >2% of patients treated with LIVALO 1 mg, 2 mg, and 4 mg, respectively, and at a rate > placebo were back pain (3.9%, 1.8%, 1.4% vs 2.9%), constipation (3.6%, 1.5%, 2.2% vs 1.9%), diarrhea (2.6%, 1.5%, 1.9% vs 1.9%), myalgia (1.9%, 2.8%, 3.1% vs 1.4%), and pain in extremity (2.3%, 0.6%, 0.9% vs 1.9%). This is not a complete listing of all reported adverse events.
