CAMBRIDGE, Mass. & CARLSBAD, Calif.--(BUSINESS WIRE)--CAMBRIDGE, Mass. & CARLSBAD, Calif.--(BUSINESS WIRE)--Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), and Isis Pharmaceuticals Inc. (NASDAQ: ISIS), announced today that new two-year data from a phase 3 long-term extension study of KYNAMROTM (mipomersen sodium) were presented at the XVI International Symposium on Atherosclerosis in Sydney, Australia. In the study, patients treated with KYNAMROTM for two years maintained robust reductions in LDL-C and all other Apo B containing atherogenic lipoproteins measured with a safety profile consistent with the phase 3 studies of KYNAMROTM.
Data presented today included 141 patients who enrolled in the study after having completed one of the three phase 3 studies: homozygous FH, severe hypercholesterolemia, or the heterozygous FH. These studies were six months long and required patients to be on stable maximally tolerated lipid-lowering therapy throughout the study. To date, 63 patients remain on or have completed treatment with 40 patients consenting to participate for another two years of treatment - a total of four years of treatment.
In this study, sustained reductions in LDL-C with a mean reduction of 28 percent in LDL-C at six months and at two years were observed in patients treated with KYNAMROTM. Changes in liver fat were observed in some patients where the overall median change stabilized and then declined with continued treatment. The median change from baseline in percent liver fat increased from 5 percent at 26 weeks, to 13 percent at 52 weeks, and returned to 5 percent at 104 weeks. Results represent those patients in the extension study at each assessment period: 60 patients at 26 weeks, 31 patients at 52 weeks, and 39 patients at 104 weeks. The median change reflects both patients who continued at full dose as well as those with dose adjustments and dose interruptions. Upon treatment discontinuation, changes in liver fat returned towards normal.
“These data show that robust LDL-C reductions are seen in patients treated for 2 years and more. Liver fat may increase in some patients but in this long term study the median fat fraction is seen to stabilize and decline with time as measured by MRI,” said study investigator Raul D. Santos, M.D., Ph.D., Director of the Lipid Clinic of the Heart institute, Instituto do Coração, Hospital das Clínicas, São Paulo, Brazil. “These results are encouraging and support the potential for effective and safe long-term use in patients with the most aggressive forms of FH.”
Genzyme and Isis have completed the four phase 3 studies that are included in the European submission and will be included in the U.S. submission. In these studies, the most commonly observed adverse events were injection site reactions and flu-like symptoms. The long-term data demonstrate a safety and efficacy profile consistent with phase 3 findings.
"These positive and clinically meaningful results represent a significant addition to the KYNAMROTM clinical development program,” said Vice President and General Manager of Genzyme’s Cardiovascular Business, Paula Soteropoulos. “We look forward to continuing to work with regulatory authorities to bring this treatment to market for such a severe and life-threatening disease.”
KYNAMRO™ is the registered trade name submitted to health authorities for investigational agent mipomersen. Genzyme submitted for EU marketing approval of KYNAMROTM for the treatment of patients with homozygous FH (HoFH) and severe heterozygous FH (Severe HeFH) in July 2011. Genzyme also expects to submit an NDA for U.S. approval for the HoFH indication by the end of March 2012.
At 4:00 p.m. Eastern Time today, Isis will host a live conference call webcast and slide presentation with Dr. Raul D. Santos to discuss KYNAMROTM data presented at the International Symposium on Atherosclerosis. Interested parties may listen to the call by dialing 866.761.0749 and refer to the passcode “ISIS 2012” or access the webcast with or without audio at www.isispharm.com. A webcast replay will be available for a limited time at the same address.
About KYNAMROTM (mipomersen sodium)
KYNAMROTM is a first-in-class Apo B synthesis inhibitor currently in late-stage development for patients with homozygous familial hypercholesterolemia (HoFH) and severe heterozygous familial hypercholesterolemia (Severe HeFH) to further reduce LDL cholesterol (LDL-C) in patients already maintaining a stable regimen of maximally tolerated lipid-lowering therapies. It is intended to reduce LDL-C by preventing the formation of atherogenic lipoproteins, the particles that carry cholesterol through the bloodstream. KYNAMROTM acts by blocking the production of, apolipoprotein B (Apo B), the protein that provides the structural core for these atherogenic particles, including LDL and lipoprotein-a (Lp(a)).
About Familial Hypercholesterolemia (FH)
FH is a genetic disease that results in elevated LDL-C levels and family patterns of increased risk of premature heart disease and heart disease-related death. FH patients have inherited abnormalities in liver cells that are responsible for clearing LDL particles from the blood. FH is autosomal dominant, which means that all first-degree relatives of FH patients have a 50 percent chance of having the disease as well, making early detection through family screening critically important.
The most severe FH patients have LDL-C levels that are two to four times higher than recommended levels, even when taking multiple cholesterol-lowering medications. These people, who are characterized as having severe FH, include: those who have inherited the disease from both parents (HoFH) and those who have inherited it from only one parent, and have a particularly severe form of the disease (Severe HeFH) defined as those people who are maximally treated and still have LDL-C greater than 200 mg/dL (5.1 mmol) with coronary heart disease or greater than 300 mg/dL (7.1 mmol) without coronary heart disease. People with HoFH may have aggressive heart disease beginning in childhood, and even with today’s therapies remain at significant risk of cardiovascular events. Learn more at www.FHJourneys.com.
