Dosage Guide
The following are general dosing guidelines only. Your actual dose should be determined by your healthcare provider based on your condition, renal/hepatic function, and other medications.
AD
Adult 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. ( 2.2 ) Physicians should consider administration of the prescribed KINERET dose every other day for NOMID patients who have severe renal insufficiency or end stage renal disease (defined as creatinine clearance < 30 mL/min, as es

- 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 infections, rash, pyrexia, influenza like illness, and gastroenteritis ( 6.3 ) To report SUSPECTED ADVERSE REACTIONS, contact Swedish Orphan Biovitrum at 1-866-547-0644 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
- 6.1 Clinical Studies Experience in RA The most serious adverse reactions were: Serious Infections – [see Warnings and Precautions ( 5.1 )] Neutropenia, particularly when used in combination with TNF blocking agents The most common adverse reaction with KINERET is injection-site reactions.
- These reactions were the most common reason for withdrawing from studies.
- The data described herein reflect exposure to KINERET in 3025 patients, including 2124 exposed for at least 6 months and 884 exposed for at least one year.
- Studies 1 and 4 used the recommended dose of 100 mg per day.
- The patients studied were representative of the general population of patients with rheumatoid arthritis.

- 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.

How Kineret Works
12.1 Mechanism of Action KINERET blocks the biologic activity of IL-1 alpha and beta by competitively inhibiting IL-1 binding to the interleukin-1 type I receptor (IL-1RI), which is expressed in a wide variety of tissues and organs. IL-1 production is induced in response to inflammatory stimuli and mediates various physiologic responses including inflammatory and immunological responses. IL-1 has a broad range of activities including cartilage degradation by its induction of the rapid loss of proteoglycans, as well as stimulation of bone resorption. The levels of the naturally occurring IL-1Ra in synovium and synovial fluid from RA patients are not sufficient to compete with the elevated amount of locally produced IL-1. Spontaneous mutations in the CIAS1/NLRP3 gene have been identified in
