    1. Adalimumab (Humira)
    2. Etanercept (Enbrel)
    3. Infliximab (Remicade)

IV. Mechanism

  1. Interleukin-1
    1. Interleukin-1 is primarly synthesized by Monocytes and Macrophages
      1. Subtypes include IL-1a and IL-1b
      2. Triggers IL-2 release from activated T Cells (via Antigens or mitogens)
    2. Pro-inflammatory Cytokine (mediates the acute phase host response)
      1. Triggeres COX2 induction, prostanoid release
      2. Sensitizes peripheral Nociceptor terminals and increases local pain sensitivity
    3. Other effects
      1. Fever (endogenous pyrogen)
      2. Myalgias and Arthralgias
      3. Anorexia
  2. Interleukin-1 Receptor Antagonist
    1. Binds to Interleukin-1 Receptors without activating them, thereby inhibiting other agents from binding

V. Medications

  1. Store in refrigerator (until 30 minutes before injection)
  2. Protect from light

VI. Dosing: Rheumatoid Arthritis

    2. Titrate in 0.5 to 1 mg/kg increments up to maximum of 8 mg/kg SQ daily
  3. Renal Adjustment
    1. Consider every other day dosing in GFR <30 ml/min

VIII. Adverse Effects

  1. Immunosuppression
    1. Use caution in any patient prone to infection
  2. Headache
  3. Injection site inflammation
  4. Gastrointestinal upset
  5. Leukopenia (including Neutropenia)

IX. Safety

  2. Unknown safety in Lactation
  3. Monitoring
    1. Serum Creatinine
    2. Complete Blood Count with Neutrophil Count
      1. Baseline, then
      2. Monthly for 3 months, then
      3. Quarterly

X. Drug Interactions

  1. Live Vaccines
    1. Hold for 1 dosing interval before and 4 weeks after Live Vaccines

Ontology: anakinra (C0245109)

Definition (NCI) A recombinant human nonglycosylated interleukin-1 (IL-1) receptor antagonist with potential antineoplastic activity. Anakinra binds to the IL-1 receptor, thereby blocking the binding of the IL-1 to and activation of its receptor. Blockade of IL-1 activity may inhibit the cascade of downstream pro-angiogenic factors such as vascular endothelial cell growth factor, tumor necrosis factor-alpha, and IL-6, resulting in inhibition of tumor angiogenesis. (NCI04)
Definition (NCI_NCI-GLOSS) A substance that is used to treat rheumatoid arthritis, and is being studied in the treatment of cancer. Anakinra blocks the action of interleukin 1 (IL-1). It is a type of interleukin receptor antagonist.
Definition (MSH) A synthetic form of native human IL-1Ra that has an additional methionine residue at its amino terminus.
Definition (PDQ) A recombinant human nonglycosylated interleukin-1 (IL-1) receptor antagonist with potential antineoplastic activity.

Ontology: Interleukin 1 Receptor Antagonist Protein (C1704264)

Definition (MSH) A ligand that binds to but fails to activate the INTERLEUKIN 1 RECEPTOR. It plays an inhibitory role in the regulation of INFLAMMATION and FEVER. Several isoforms of the protein exist due to multiple ALTERNATIVE SPLICING of its mRNA.
Definition (NCI) Interleukin-1 receptor antagonist protein (177 aa, ~20 kDa) is encoded by the human IL1RN gene. This protein is involved in the inhibition of the interaction between interleukin-1 and its receptor.
