Isis Updates Kynamro Submission Timeline

Genzyme plans to submit in the first quarter of 2012

CARLSBAD, Calif., Dec. 15, 2011 /PRNewswire/ -- Isis Pharmaceuticals, Inc. (NASDAQ: ISIS) announced today that there will be a slight delay in the submission of the new drug application (NDA) to the United States Food and Drug Administration for KYNAMRO™(mipomersen sodium).  This additional time will allow Genzyme to complete preparation of additional technical documentation. The submission of the U.S. NDA seeking approval of KYNAMRO for the treatment of homozygous familial hypercholesterolemia (FH) is now planned for the first quarter of 2012.

In July of this year, Genzyme and Isis submitted a marketing authorization application to the European Medicines Agency seeking approval for KYNAMRO for the treatment of patients with homozygous and severe heterozygous FH.

About KYNAMRO (mipomersen sodium)

KYNAMRO is a first-in-class apo-B synthesis inhibitor currently in late-stage development for the reduction of LDL cholesterol (LDL-C).  It is intended to reduce LDL-C by preventing the formation of atherogenic lipoproteins, the particles that carry cholesterol through the bloodstream.  KYNAMRO acts by blocking the production of apolipoprotein B (apoB), the protein that provides the structural core for these atherogenic particles, including LDL and lipoprotein-a (Lp(a)).

About Familial Hypercholesterolemia

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 (homozygous FH (HoFH)) and those who have inherited it from only one parent, and have a severe form of the disease (severe heterozygous FH (severe HeFH)).
