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).
- 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 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.
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.
