Introduction
Interleukin-1 beta (IL-1β) blocker; a recombinant human anti-human IL-1β monoclonal antibody.1 2 3
Uses for Ilaris
Cryopyrin-associated Periodic Syndromes
Management of cryopyrin-associated periodic syndromes (CAPS), including familial cold autoinflammatory syndrome (FCAS) and Muckle-Wells syndrome (MWS), in adults and children ≥4 years of age;1 2 3 designated an orphan drug by FDA for use in these conditions.3 4
Results in clinical remission, based on physician’s assessment of global disease activity, in a majority of patients with MWS or FCAS.1 2 Also results in decreases in mean concentrations of acute phase reactants (serum amyloid A [SAA] and C-reactive protein [CRP]).1 2
Ilaris Dosage and Administration
Administration
Sub-Q Administration
Administer by sub-Q injection.1
Injections should be performed by a clinician; the drug is not intended for self-administration.1 5
Do not inject into scar tissue; this may result in insufficient exposure to the drug.1 Do not inject into areas where skin is already swollen or erythematous.1
Reconstitution
Reconstitute canakinumab lyophilized powder for injection by slowly adding 1 mL of preservative-free sterile water for injection (using a 1-mL syringe with an 18-gauge, 2-inch needle) to a vial containing 180 mg of canakinumab to provide a solution containing 150 mg/mL.1
Slowly swirl vial at an angle of about 45° for approximately one minute. Allow to stand for 5 minutes and then gently invert vial 10 times; slight foaming may occur.1 Do not touch rubber stopper or shake vial.1 Allow reconstituted solution to stand at room temperature for approximately 15 minutes to obtain a clear solution.1 Tap the side of the vial to remove any residual liquid from the stopper.1 The reconstituted solution should be clear to opalescent, colorless to slightly brownish-yellow, and essentially free from particulates.1
Before administration, withdraw the appropriate dose into a syringe using a 27-gauge, ½-inch needle.1 Discard unused portions of the reconstituted solution; the solution contains no preservatives.1

Warnings/Precautions
Infectious Complications
IL-1 blockade may interfere with immune response to infections; possible increased risk of serious infections.1 2 Potentially serious infections, predominantly involving the upper respiratory tract, reported.1 Unusual or opportunistic infections not reported during premarketing studies.1
Do not initiate canakinumab in patients with an active infection requiring medical treatment or a chronic infection (e.g., HIV, HBV, or HCV infection); discontinue therapy if a serious infection occurs.1 Use with caution in patients with infections, a history of recurring infections, or underlying conditions which may predispose them to infections.1
May increase risk of tuberculosis or other atypical or opportunistic infections.1 Evaluate patients for latent tuberculosis prior to initiation of canakinumab therapy.1 Not studied in patients with latent tuberculosis infection; safety in such patients not known.1 When indicated, initiate appropriate antimycobacterial regimen for treatment of latent tuberculosis infection prior to canakinumab therapy.1
Immunosuppression and Malignancies
Effect on the development of malignancies not known.1 However, possible increased risk of malignancies in patients receiving immunosuppressive agents, including canakinumab.1
Immunization
Avoid live vaccines during canakinumab therapy.1 (See Vaccines under Interactions.)
Vaccine efficacy may be reduced.1 Review vaccination status of all patients and administer all age-appropriate vaccines, including pneumococcal vaccine and influenza virus vaccine inactivated, prior to initiation of canakinumab therapy.1
Immunologic Effects and Antibody Formation
Development of antibodies to canakinumab not reported to date.1 2 3
Specific Populations
Pregnancy
Category C.1
Lactation
Not known whether canakinumab is distributed into milk.1 Caution if used in nursing women.1
Pediatric Use
Safety and efficacy not established in children <4 years of age.1
Evaluated in 23 pediatric patients 4–17 years of age with CAPS; symptoms and objective markers of inflammation improved in most patients and overall efficacy and safety were similar to those observed in adults.1
Geriatric Use
Insufficient experience in patients ≥65 years of age to determine whether geriatric patients respond differently than younger adults.1
Hepatic Impairment
Pharmacokinetics not studied in patients with hepatic impairment.1
Renal Impairment
Pharmacokinetics not studied in patients with renal impairment.1
Common Adverse Effects
Nasopharyngitis, diarrhea, influenza, rhinitis, headache, nausea, bronchitis, gastroenteritis, musculoskeletal pain, pharyngitis, vertigo, weight gain, injection site reactions.1
Interactions for Ilaris
No formal drug interaction studies to date.1
Drugs Metabolized by Hepatic Microsomal Enzymes
Because increased levels of cytokines (e.g., IL-1) during chronic inflammation may suppress formation of CYP isoenzymes, antagonism of IL-1 activity by canakinumab may normalize formation of CYP enzymes.1
Drugs metabolized by CYP isoenzymes that have a low therapeutic index: Monitor therapeutic effect and/or serum concentrations following initiation of canakinumab; adjust dosage of the CYP substrate as needed.1
Vaccines
Data not available regarding efficacy of inactivated vaccines in patients receiving canakinumab.1 (See Immunization under Cautions.)
Do not administer live vaccines to patients receiving canakinumab.1 Data not available regarding efficacy of live vaccines or risk of secondary transmission of infection by live vaccines in patients receiving the drug.1
Manufacturer makes no specific recommendations regarding the length of time to wait between discontinuance of canakinumab and administration of a live vaccine or the length of time to wait between administration of a live vaccine and initiation of canakinumab therapy.1

Actions
-
Recombinant human anti-human interleukin-1 beta (IL-1β) monoclonal antibody belonging to the IgG1/κ isotype subclass.1 3
-
Binds to IL-1β and neutralizes its activity by blocking its interaction with IL-1 receptors;1 2 does not bind interleukin-1 alpha (IL-1α) or interleukin-1 receptor antagonist (IL-1Ra).1 2 3 Mutations in the NLRP-3 gene in patients with CAPS result in an overactive inflammasome, which causes excessive release of activated IL-1β.1
-
Results in normalization of serum concentrations of SAA and CRP, indicators of inflammatory disease activity.1 Elevated SAA concentrations have been associated with the development of systemic amyloidosis in patients with CAPS.1
Advice to Patients
-
Importance of providing a copy of the manufacturer’s patient information to all patients.1 5 Importance of discussing any questions pertaining to the manufacturer’s patient information.1 5
-
Risk of injection site reactions (e.g., pain, erythema, swelling, pruritus, bruising, mass, inflammation, dermatitis, edema, urticaria, vesicles, warmth, hemorrhage).1 Importance of informing clinician of any persistent injection site reaction.1
-
Risk of serious infection.1 Importance of informing clinicians immediately if any signs or symptoms of infection (e.g., fever, cough, redness in one part of the body, warmth or swelling of the skin) occur.1 5
-
Risk of vertigo.1 5
-
Importance of reviewing vaccination status with clinician and receiving all age-appropriate vaccines prior to initiation of canakinumab therapy.1
-
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription (e.g., IL-1 antagonists, TNF-blocking agents, immunizations, corticosteroids) or OTC drugs, dietary supplements, and/or herbal products, as well as any concomitant illnesses (e.g., active or chronic infections).1 5
-
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1 5
-
Importance of informing patients of other important precautionary information.1 (See Cautions.)
