Pitavastatin Demonstrates Sustained Efficacy, Tolerability and LDL-C Target Attainment Over 52 Weeks


Wokingham, England, April 28, 2010 (ots/PRNewswire) - New long-termphase III data published today in Atherosclerosis demonstrates that,of patients with primary hypercholesterolaemia or combineddyslipidaemia who received 4mg of pitavastatin, 74% and 73.5%achieved NCEP* and EAS* low-density lipoprotein cholesterol (LDL-C)targets at 52 weeks, respectively. At the end of this open-labelone-year extension study, reductions in LDL-C observed duringprevious 12-week double-blind phase III studies were maintained(104.3 mg/dL at week 52 compared with 105.6 mg/dL at the end of thedouble-blind phase). Furthermore, high-density lipoproteincholesterol (HDL-C) levels rose continually over 52 weeks, with anoverall increase of 14.3% from initial baseline, while changes inother efficacy parameters and ratios** were sustained during 52 weekstreatment compared with the end of the double-blind studies. Thesedata demonstrate sustained efficacy of pitavastatin over thelong-term.

Statins are considered the mainstay of dyslipidaemia treatment,however many patients do not reach clinically optimal lipidtargets.(1-4) Previous studies have demonstrated that around half ofpatients failed to reach LDL-C targets with the initially prescribeddose of statin, and that of these, 86% had still not reached LDL-Ctarget after six months, despite dose adjustment and use of theclinician's statin of choice.(5) Furthermore, 68.2% of patients in UKgeneral practice failed to reach optimal clinical levels of HDL-Cwithin a year of starting statin therapy;(6) these studies suggestthere is an unmet clinical need in the management of dyslipidaemia.

"This study confirms that pitavastatin is an effective and welltolerated long-term treatment option for patients withhypercholesterolaemia or combined dyslipidaemia," commented Dr. LeivOse, MD PhD, Rikshospitalet, Oslo University Hospital, Norway, andStudy Investigator. "Many patients do not reach LDL-C targets ontheir current treatment regimen, and this can be said for otherimportant lipid parameters including HDL-C. A statin which has thepotential to help healthcare professionals and patients alike achievelipid targets represents a welcome treatment option for the future."

Prior to this extension study, all patients had previously takenpart in one of two double-blind studies, and had receivedpitavastatin (2mg or 4mg QD), atorvastatin (10mg or 20mg QD) orsimvastatin (20mg or 40mg QD) for 12 weeks. On completion of the twostudies, 1353 patients (42.5% males / 57.5% females; mean age 58.6years) took part in this open-label extension study to assess thelong-term safety and tolerability of pitavastatin 4mg QD for up to 52weeks; secondary objectives were to assess NCEP and EAS LDL-C targetattainment, other lipid and lipoprotein fractions.

*National Cholesterol Education Program (NCEP) and European Atherosclerosis Society (EAS) **Efficacy parameters (Triglycerides, total cholesterol, non-HDL-C, Apo-A1 and Apo-B, high sensitivity C-reactive protein, oxidized LDL ) and ratios (total cholesterol: HDL-C, non-HDL-C:HDL-C and Apo-B:Apo-A1)

Pitavastatin was well tolerated to 52 weeks; no serioustreatment-emergent adverse event (TEAE) was related to pitavastatin,with the most commonly reported TEAEs being increased bloodcreatinine kinase (5.8%), nasopharyngitis (5.4%) and myalgia (4.1%).Additionally, there were no clinically significant abnormalities inroutine laboratory variables, urinalysis, vital signs or 12-lead ECG.Pitavastatin also demonstrated a favourable safety and tolerabilityprofile throughout the extension study, exemplified by a low rate ofdiscontinuations due to adverse events.

"Data from this pivotal, phase III study demonstratespitavastatin's sustained and robust efficacy, safety and tolerabilityprofile" said Dr Neil Hounslow, Vice President of scientific affairs,Kowa Research Europe. "With sustained efficacy, low rates ofdiscontinuations due to adverse events and continued increases inHDL-C observed over 52 weeks, pitavastatin could provide clinicianswith a new option in the long-term treatment of patients withhypercholesterolaemia or combined dyslipidaemia."

About pitavastatin

Pitavastatin (a statin) is a fully synthetic and highly potentinhibitor of HMG-CoA reductase used for primary hypercholesterolaemiaand combined dyslipidaemia. Pitavastatin has a unique cyclopropylgroup on the base structure common to the statin class. Since its2003 launch in Japan, pitavastatin has accumulated millions ofpatient-years of exposure. Many of these patients have comorbiditiesand are taking multiple medications. Kowa received FDA approval ofpitavastatin (LIVALO(R)) for the treatment of primaryhypercholesterolaemia and combined dyslipidaemia in August 2009 andit will be launched in the U.S. in June 2010. Additionally, Kowafiled in Europe in August 2008 using the decentralised authorisationprocedure and is due to receive a regulatory approval in mid 2010. Inmuch of Europe, pitavastatin will be marketed by Recordati.Pitavastatin will be available in three dosage strengths (1 mg, 2 mgand 4 mg).
