Anakinra
Generic Name: anakinra
Brand Names:
Kineret
11 DESCRIPTION KINERET (anakinra) is a recombinant , nonglycosylated form of the human interleukin-1 receptor antagonist (IL-1Ra). KINERET differs from native human IL-1Ra in that it has the addition of a single methionine residue at its amino terminus. KINERET consists of 153 amino acids and has a molecular weight of 17.3 kilodaltons. It is produced by recombinant DNA technology using an E coli bacterial expression system.

Uses
1 INDICATIONS AND USAGE KINERET is an interleukin-1 receptor antagonist indicated for: Rheumatoid Arthritis (RA) Reduction in signs and symptoms and slowing the progression of structural damage in moderately to severely active rheumatoid arthritis, in patients 18 years of age or older who have failed 1 or more disease modifying antirheumatic drugs (DMARDs) ( 1.1 ) Cryopyrin-Associated Periodic Syndromes (CAPS) Treatment of Neonatal-Onset Multisystem Inflammatory Disease (NOMID) ( 1.2 ) Deficiency of Interleukin-1 Receptor Antagonist (DIRA) Treatment of Deficiency of Interleukin-1 Receptor Antagonist (DIRA) ( 1.3 ) 1.1 Active Rheumatoid Arthritis KINERET is indicated for the reduction in signs and symptoms and slowing the progression of structural damage in moderately to severely active rhe...
Dosage
2 DOSAGE AND ADMINISTRATION Rheumatoid Arthritis (RA) The recommended dose of KINERET for the treatment of patients with rheumatoid arthritis is 100 mg/day administered daily by subcutaneous injection. The dose should be administered at approximately the same time every day ( 2.1 ) Physicians should consider a dose of 100 mg of KINERET administered every other day for RA patients who have severe renal insufficiency or end stage renal disease (defined as creatinine clearance < 30 mL/min, as estimated from serum creatinine levels) ( 2.4 ) Cryopyrin-Associated Periodic Syndromes (CAPS) The recommended starting dose of KINERET is 1-2 mg/kg daily for NOMID patients. The dose can be individually adjusted to a maximum of 8 mg/kg daily to control active inflammation.
Side Effects
6 ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Rheumatoid Arthritis (RA) Most common adverse reactions (incidence ≥ 5%) are injection site reaction, worsening of rheumatoid arthritis, upper respiratory tract infection, headache, nausea, diarrhea, sinusitis, arthralgia, flu like-symptoms, and abdominal pain ( 6.1 ) NOMID The most common AEs during the first 6 months of treatment (incidence > 10%) are injection site reaction, headache, vomiting, arthralgia, pyrexia, and nasopharyngitis ( 6.2 ) DIRA The most common AEs are upper respiratory tract infe...
Interactions
7 DRUG INTERACTIONS No drug-drug interaction studies in human subjects have been conducted. Toxicologic and toxicokinetic studies in rats did not demonstrate any alterations in the clearance or toxicologic profile of either methotrexate or KINERET when the two agents were administered together. A higher rate of serious infections has been observed in RA patients treated with concurrent KINERET and etanercept therapy than in patients treated with etanercept alone. Use of KINERET in combination with TNF blocking agents is not recommended ( 7 ) 7.1 TNF Blocking Agents A higher rate of serious infections has been observed in patients treated with concurrent KINERET and etanercept therapy than in patients treated with etanercept alone [see Warnings and Precautions ( 5.2 )] .
Warnings
5 WARNINGS AND PRECAUTIONS In RA, discontinue use if serious infection develops. In KINERET-treated NOMID or DIRA patients, the risk of a disease flare when discontinuing KINERET treatment should be weighed against the potential risk of continued treatment. Do not initiate KINERET in patients with active infections. ( 5.1 ) Use in combination with Tumor Necrosis Factor (TNF) blocking agents is not recommended ( 5.2 ) Hypersensitivity reactions, including anaphylactic reactions and angioedema, and serious cutaneous reactions including Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) can occur; discontinue KINERET, treat promptly, and monitor until reaction resolves. 4 CONTRAINDICATIONS KINERET is contraindicated in patients with known hypersensitivity to E coli -derived proteins, KINERET, or any components of the product [see Hypersensitivity Reactions ( 5.3 )] . Known hypersensitivity to E coli -derived proteins, Kineret, or to any component of the product. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Available data from retrospective studies and case reports on KINERET use in pregnant women are insufficient to identify a drug associated risk of major birth defects, miscarriage, or maternal and fetal adverse events. There are risks to the mother and fetus associated with active rheumatoid arthritis or Cryopyrin-Associated Periodic Syndromes (CAPS).
Storage
Storage KINERET should be stored in the refrigerator at 2°C to 8°C (36°F to 46°F). DO NOT FREEZE OR SHAKE. Protect from light. Rx only
