(NASDAQ: ISIS), today announced that the U.S. Food and Drug Administration (FDA) has approved its New Drug Application (NDA) for KYNAMROTM (mipomersen sodium) injection. KYNAMRO, given as a 200 mg weekly subcutaneous injection, has been approved as an adjunct to lipid-lowering medications and diet to reduce low density lipoprotein-cholesterol (LDL-C), apolipoprotein B (Apo B), total cholesterol (TC), and non-high density lipoprotein-cholesterol (non HDL-C) in patients with homozygous familial hypercholesterolemia (HoFH). "Today`s FDA approval of KYNAMRO is great news for patients with HoFH who are in need of additional treatment options for this rare, and often under-diagnosed disease," said Genzyme President and CEO, David Meeker, M.D. "As the leader in treatments for rare diseases, we are pleased to bring our expertise to HoFH patients living with this serious condition to better help them manage their disease." HoFH is a rare inherited condition that makes the body unable to remove LDL cholesterol, often called the "bad" cholesterol, from the blood, causing abnormally high levels of circulating LDL cholesterol. In the United States, HoFH, an orphan indication, occurs in approximately one in one million individuals. For those with HoFH, heart attacks and death often occur before age 30. "People living with Homozygous FH may not appear to be sick, but they live with the burden of this rare disease every day," said Katherine Wilemon, President and Founder the FH Foundation "The approval of KYNAMRO gives the HoFH community hope that HoFH can be effectively managed." The FDA approval triggers a $25 million milestone payment to Isis from Genzyme. "KYNAMRO is the first systemic antisense drug to reach the market and is the culmination of two decades of work to create a new, more efficient drug technology platform. As evidenced by our robust pipeline, ourantisense drug discovery technology is applicable to many different diseases, including the treatment of a chronic and rare disease, like HoFH," said Stanley T. Crooke, M.D., Ph.D., Chairman of the Board and CEO of Isis. "We look forward to continuing to work with Genzyme toward a successful commercial launch of KYNAMRO and global expansion into other markets." The FDA approval for KYNAMRO is supported by the largest clinical trial conducted to-date in the HoFH patient population. The randomized, double-blind, placebo-controlled, multi-center trial enrolled 51 patients age 12 to 53 years, including 7 patients age 12 to 16 years, who were maintaining a regimen of maximally-tolerated lipid lowering medications. Treatment with KYNAMRO further reduced LDL-C levels by an average of 113 mg/dL, or 25%, from a treated baseline of 439 mg/dL, and further reduced all measured endpoints for atherogenic particles. In March 2010, these data were published in The Lancet by Professor Raal, University of the Witwatersrand in South Africa. Safety data for KYNAMRO are based on pooled results from four Phase 3, randomized, double-blind, placebo-controlled trials with a total of 390 patients of which 261 patients received weekly subcutaneous injections of 200 mg of KYNAMRO and 129 patients received placebo for a median treatment duration of 25 weeks. Eighteen percent of patients on KYNAMRO and 2% of patients on placebo discontinued treatment due to adverse reactions. The most common adverse reactions in patients treated with KYNAMRO that led to treatment discontinuation and occurred at a rate greater than placebo were: injection site reactions (5.0%), alanine aminotransferase (ALT) increased (3.4%), flu-like symptoms (2.7%), aspartate aminotransferase (AST) increased (2.3%), and liver function test abnormal (1.5%). KYNAMRO is an antisense drug and is metabolized without affecting the CYP450 pathways used in commonly prescribed drugs, and thus has potential for no drug-drug interactions. No clinically relevant pharmacokinetic interactions were reported between KYNAMRO and warfarin, or between KYNAMRO and simvastatin or ezetimibe. KYNAMRO contains a Boxed Warning citing the risk of hepatic toxicity. Patients taking KYNAMRO should have liver enzyme testing before starting the drug and periodically thereafter. See below for Important Safety Information about KYNAMRO. The safety and effectiveness of KYNAMRO have not been established in patients with hypercholesterolemia who do not have HoFH. The effect of KYNAMRO on cardiovascular morbidity and mortality has not been determined. Because of the risk of hepatotoxicity, KYNAMRO is available only through a Risk Evaluation and Mitigation Strategy (REMS) called the KYNAMRO REMS. The goals of the KYNAMRO REMS are: * To educate prescribers about the risk of hepatotoxicity associated with the use of KYNAMRO, and the need to monitor patients during treatment with KYNAMRO as per product labeling. * To restrict access to therapy with KYNAMRO to patients with a clinical or laboratory diagnosis consistent with homozygous familial hypercholesterolemia (HoFH). As part of its commitment to HoFH patients, Genzyme has developed KYNAMRO CornerstoneSM, an HoFH and KYNAMRO support program for healthcare providers, patients, and their families. KYNAMRO Cornerstone services include: * Dedicated KYNAMRO Cornerstone Case Managers. * Product & disease education for providers, patients, and families. * In-person injection training, if requested. * Reimbursement support, including out-of-pocket financial support, for patients who qualify. * Coordination of KYNAMRO shipment and delivery. KYNAMRO Cornerstone Case Managers are available live Monday-Friday from 9 am to 6 pm Eastern time. For more information about KYNAMRO Cornerstone, or about these support services call 1-877-KYNAMRO (877-596-2676). For additional information, please visit www.KYNAMRO.com. IMPORTANT SAFETY INFORMATION WARNING: RISK OF HEPATOTOXICITY KYNAMRO can cause elevations in transaminases. In the KYNAMRO clinical trial in patients with HoFH, 4 (12%) of the 34 patients treated with KYNAMRO compared with 0% of the 17 patients treated with placebo had at least one elevation in alanine aminotransferase (ALT) ≥3x upper limit of normal (ULN). There were no concomitant clinically meaningful elevations of total bilirubin, international normalized ratio (INR) or partial thromboplastin time (PTT). KYNAMRO also increases hepatic fat, with or without concomitant increases in transaminases. In the trials in patients with heterozygous familial hypercholesterolemia (HeFH) and hyperlipidemia, the median absolute increase in hepatic fat was 10% after 26 weeks of treatment, from 0% at baseline, measured by magnetic resonance imaging (MRI).Hepatic steatosis is a risk factor for advanced liver disease; including steatohepatitis and cirrhosis. Measure ALT, AST, alkaline phosphatase, and total bilirubin before initiating treatment and then ALT, AST regularly as recommended. During treatment, withhold the dose of KYNAMRO if the ALT or AST are ≥3 x ULN. Discontinue KYNAMRO for clinically significant liver toxicity. Because of the risk of hepatotoxicity, KYNAMRO is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the KYNAMRO REMS. OTHER WARNINGS AND PRECAUTIONS Patients are advised to read the KYNAMRO medication guide before starting treatment with KYNAMRO, and each time they receive a refill. There may be new information. This information does not take the place of talking to a doctor about a medical condition or treatment. KYNAMRO may cause serious side effects, including liver problems. A doctor should be informed of any liver problems, including liver problems while taking other medicines, or if a patient has any of these symptoms of liver problems while taking KYNAMRO: nausea, vomiting, fever, loss of appetite, being (or feeling) more tired than usual, yellowing of eyes or skin, dark urine, itching, or stomach pain. Alcohol may increase levels of hepatic fat and induce or exacerbate liver injury. It is recommended that patients taking KYNAMRO should consume no more than one alcoholic drink per day. Caution should be exercised when KYNAMRO is used with other medications known to have potential for hepatotoxicity. KYNAMRO should be used during pregnancy only if clearly needed. Females who become pregnant during KYNAMRO therapy should notify their healthcare provider. Safety and effectiveness have not been established in pediatric patients. KYNAMRO is not recommended in patients with severe renal impairment, clinically significant proteinuria, or on renal dialysis. The safety and effectiveness of KYNAMRO as an adjunct to LDL apheresis have not been established; therefore, the use of KYNAMRO as an adjunct to LDL apheresis is not recommended. CONTRAINDICATIONS KYNAMRO is contraindicated in the following conditions: * Moderate or severe hepatic impairment (Child-Pugh B or C) or active liver disease, including unexplained persistent elevations of serum transaminases. * Patients with a known hypersensitivity to any component of this product. COMMON SIDE EFFECTS In clinical trials the most commonly-reported adverse reactions were injection site reactions occurring in 84% of patients receiving KYNAMRO versus 33% of placebo treated patients. The most common injection site reactions were erythema (59%), pain (56%), hematoma (32%), pruritus (29%), swelling (18%) and discoloration (17%). Injection site reactions did not occur with every injection but resulted in discontinuation of therapy in 5% of patients in pooled phase 3 trials. Flu-like symptoms, defined as any one of the following: influenza-like illness, pyrexia, chills, myalgia, arthralgia, malaise or fatigue and occurring within 2 days of injection, have been reported more frequently in patients receiving KYNAMRO (30%) versus placebo (16%) in the pooled Phase 3 trials. Flu-like symptoms did not occur with all injections but resulted in discontinuation of therapy in 3% of patients in pooled phase 3 trials. See full prescribing information for more details about Warnings & Precautions, complete list of Adverse Reactions and Boxed Warning. About KYNAMRO (mipomersen sodium) injection KYNAMRO is indicated as a first-in-class, oligonucleotide inhibitor, of apolipoprotein B-100 synthesis. KYNAMRO is an adjunct to lipid-lowering medications and diet to reduce low density lipoprotein-cholesterol (LDL-C), apolipoprotein B (apo B), total cholesterol (TC), and non-high density lipoprotein-cholesterol (non HDL-C) in patients with homozygous familial hypercholesterolemia (HoFH). KYNAMRO reduces LDL-C by preventing the formation of atherogenic lipoproteins, the particles that carry cholesterol through the bloodstream. KYNAMRO acts by blocking the production of apo B, the protein that provides the structural core for these atherogenic particles, including LDL. About Homozygous Familial Hypercholesterolemia (HoFH) HoFH is a rare genetic disease characterized by extreme cholesterol levels. People with HoFH have inherited mutations that limit the body`s ability to clear cholesterol. HoFH is extremely rare: it is believed to occur in only one out of every one million persons. As with other rare diseases, the true prevalence of HoFH may be underestimated because of inadequate data and under-diagnosis. Today, it is estimated that HoFH affects about 6,000 people globally. Medical literature includes different criteria for marking an HoFH diagnosis. HoFH may be diagnosed by clinical or genetic parameters, and may be considered in cases of unusually high LDL-C, such as greater than 500 mg/dL without treatment, or 300 mg/dL after taking cholesterol-lowering medication. Because HoFH is genetic, it is important that all family members of people with HoFH know their cholesterol levels, regardless of their age.
