Black Box Warning

WARNING: RISK OF HEPATOTOXICITY See full prescribing information for complete Boxed Warning. * 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 ≥ 3x 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.

Overview

Mipomersen is a lipid-lowering medication that is FDA approved for the {{{indicationType}}} of hypercholesterolemia. There is a Black Box Warning for this drug as shown here. Common adverse reactions include injection site reactions, flu-like symptoms, nausea, headache, and elevations in serum transaminases, specifically ALT.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Homozygous Familial Hypercholesterolemia (HoFH)

• KYNAMROTM is indicated 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).

• Limitations of Use

• 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.
• 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.

• Dosing Information

• Before beginning treatment with KYNAMRO, measure transaminases (ALT, AST), alkaline phosphatase, and total bilirubin.
• The recommended dose of KYNAMRO is 200 milligrams (mg) once weekly as a subcutaneous injection.
• KYNAMRO is intended for subcutaneous use only. Do not administer intramuscularly or intravenously.
• The injection should be given on the same day every week, but if a dose is missed, the injection should be given at least 3 days from the next weekly dose.
• After initiation of KYNAMRO therapy lipid levels should be monitored at least every 3 months for the first year. Maximal reduction of LDL-C may be seen with KYNAMRO therapy after approximately 6 months (based on the time to steady state seen in clinical studies). Health care providers should assess the patient’s LDL-C level after 6 months to determine if the LDL-C reduction achieved with KYNAMRO is sufficiently robust to warrant the potential risk of liver toxicity.

• Administration

• Each vial or pre-filled syringe of KYNAMRO provides 200 mg of mipomersen sodium in a deliverable volume of 1 milliliter (mL) of solution and is intended for single-use only.
• The KYNAMRO vial or pre-filled syringe should be removed from 2-8°C (36-46°F) refrigerated storage and allowed to reach room temperature for at least 30 minutes prior to administration.
• Parenteral drug products should be inspected visually prior to administration. If the solution is cloudy or contains visible particulate matter, the contents must not be injected and the product should be returned to the pharmacy.
• The first injection administered by the patient or caregiver should be performed under the guidance and supervision of an appropriately qualified health care professional.
• KYNAMRO should be injected into the abdomen, thigh region, or outer area of the upper arm. KYNAMRO should not be injected in areas of active skin disease or injury such as sunburns, skin rashes, inflammation, skin infections, active areas of psoriasis, etc. Areas of tattooed skin and scarring should also be avoided.

• Adjustments for Patients Developing Transaminase Elevations

• Table 1 summarizes recommendations for monitoring for patients who develop elevated transaminases during therapy with KYNAMRO.

This image is provided by the National Library of Medicine.

• If transaminase elevations are accompanied by clinical symptoms of liver injury (e.g., nausea, vomiting, abdominal pain, fever, jaundice, lethargy, flu-like symptoms), increases in bilirubin ≥ 2x ULN, or active liver disease, discontinue treatment with KYNAMRO and investigate to identify the probable cause.
