Special Alerts:
[Posted 09/07/2011] ISSUE: FDA notified healthcare professionals that the Boxed Warning for the entire class of Tumor Necrosis Factor-alpha (TNF) blockers has been updated to include the risk of infection from two bacterial pathogens, Legionella and Listeria. In addition, the Boxed Warning and Warnings and Precautions sections of the labels for all of the TNF blockers have been revised so that they contain consistent information about the risk for serious infections and the associated disease-causing pathogens.
Patients treated with TNF blockers are at increased risk for developing serious infections involving multiple organ systems and sites that may lead to hospitalization or death due to bacterial, mycobacterial, fungal, viral, parasitic, and other opportunistic pathogens.
BACKGROUND: The class of TNF blockers are used to treat Crohn's disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, plaque psoriasis, and/or juvenile idiopathic arthritis.
RECOMMENDATION: The risks and the benefits of TNF blockers should be considered prior to initiating therapy in patients with chronic or recurrent infection and patients with underlying conditions that may predispose them to infection. See the Drug Safety Communication for a listing of recommendations for healthcare professionals and patients, as well as a data summary. For more information visit the FDA website at: and .
REMS:
FDA approved a REMS for certolizumab pegol to ensure that the benefits of a drug outweigh the risks. The REMS may apply to one or more preparations of certolizumab pegol and consists of the following: medication guide and communication plan. See the FDA REMS page () or the ASHP REMS Resource Center ().
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
- Serious Infections
Serious, sometimes fatal infections including tuberculosis (frequently disseminated or extrapulmonary), bacterial and viral infections, invasive fungal infections (may be disseminated), and other opportunistic infections reported.1 (See Infectious Complications under Cautions.)
Carefully consider risks and benefits prior to initiating certolizumab pegol therapy in patients with chronic or recurring infections.1
Evaluate patients for latent tuberculosis infection prior to and periodically during certolizumab pegol therapy; if indicated, initiate appropriate antimycobacterial regimen prior to initiating therapy.1
Closely monitor patients for infection, including active tuberculosis in those with a negative tuberculin skin test, during and after treatment.1 Discontinue certolizumab pegol if serious infection occurs.1 Consider empiric antifungal therapy if serious systemic illness occurs in a patient at risk for invasive fungal infections.1

Cimzia Dosage and Administration
General
REMS Program
FDA has approved a REMS for certolizumab pegol.11
The program consists of a medication guide that must be provided to patients (see Advice to Patients) and a communication plan that includes initial communications targeting selected groups of clinicians.11
The goals are to inform patients about the serious risks associated with the drug and to inform clinicians about invasive fungal infections associated with use of TNF blocking agents (see Warnings/Precautions under Cautions).11
Administration
Sub-Q Administration
Administer by sub-Q injection into the thighs or abdomen using a 23-gauge needle.1 Rotate injection sites.1 Do not inject into areas where the skin is tender, bruised, red, or hard.1
Allow reconstituted solution and prefilled syringes sit at room temperature for 30 minutes prior to administration.1
Following reconstitution, draw up each 400 mg dose into 2 syringes, each containing 200 mg, and administer by sub-Q injection into separate sites on the thighs or abdomen using 23-gauge needles.1
Reconstituted solution intended for use under the guidance and supervision of a clinician.1 Certolizumab pegol solution supplied in prefilled syringes may be self-administered if the clinician determines that the patient and/or their caregiver is competent to safely administer the drug after appropriate training.1
Reconstitution
Allow lyophilized powder kit (containing drug, diluent, syringes, needles) to reach room temperature prior to reconstitution.1
Reconstitute vial containing 200 mg of certolizumab pegol lyophilized powder by adding 1 mL of sterile water for injection (provided by manufacturer) to provide a solution containing approximately 200 mg/mL.1
Gently swirl vial to ensure all of the powder comes into contact with the diluent; do not shake.1 Leave vial undisturbed to fully reconstitute (may take up to 30 minutes).1

Infectious Complications
Pending revision, the material in this section should be considered in light of more recently available information in the MedWatch notification at the beginning of this monograph.
Serious, sometimes fatal infections (including bacterial, mycobacterial, invasive fungal, viral, or other opportunistic infections) reported with certolizumab pegol and other TNF blocking agents, particularly in patients receiving concomitant therapy with immunosuppressive agents (e.g., methotrexate, corticosteroids).1 The most common opportunistic infections include , histoplasmosis, aspergillosis, candidiasis, coccidioidomycosis, listeriosis, and pneumocystosis.1 Infections frequently are disseminated.1
Do not initiate certolizumab pegol in patients with active infections, including clinically important localized infections.1 Consider potential risks and benefits of the drug prior to initiating therapy in patients with a history of chronic or recurring infections; patients with underlying conditions that may predispose them to infections; and patients who have been exposed to tuberculosis or who have resided or traveled in regions where tuberculosis or mycoses such as histoplasmosis, coccidioidomycosis, or blastomycosis are endemic.1
Closely monitor patients during and after treatment for signs or symptoms of infection (e.g., fever, malaise, weight loss, sweats, cough, dyspnea, pulmonary infiltrates, serious systemic illness including shock).1 6
If new infection occurs during therapy, perform thorough diagnostic evaluation (appropriate for immunocompromised patient), initiate appropriate anti-infective therapy, and closely monitor patient.1 6 Discontinue certolizumab pegol if serious infection or sepsis develops.1 6
Evaluate all patients for active or latent tuberculosis and for risk factors for tuberculosis prior to and periodically during therapy.1 When indicated, initiate appropriate antimycobacterial regimen for treatment of latent tuberculosis infection prior to certolizumab pegol therapy.1 Consider antimycobacterial therapy prior to initiating certolizumab pegol in patients with a history of latent or active tuberculosis for whom adequate antimycobacterial treatment is unconfirmed, and in patients with a negative tuberculin skin test who have risk factors for tuberculosis.1 Consultation with a tuberculosis specialist is recommended when deciding whether to initiate antimycobacterial therapy.1
Monitor all patients, including those with negative tuberculin skin tests, for active tuberculosis.1 Strongly consider tuberculosis in patients who develop new infections during therapy, especially if they previously have traveled to countries where tuberculosis is highly prevalent or have been in close contact with an individual with active tuberculosis.1
Invasive fungal infections often not recognized in patients receiving TNF blocking agents; this has led to delays in appropriate treatment.6
Consider empiric antifungal therapy in patients at risk for invasive fungal infections who develop severe systemic illness.1 6 Whenever feasible, consult specialist in fungal infections when making decisions regarding initiation and duration of antifungal therapy.1 6
When deciding whether to reinitiate TNF blocking agent therapy following resolution of an invasive fungal infection, reevaluate risks and benefits, particularly in patients who reside in regions where mycoses are endemic.6 Whenever feasible, consult specialist in fungal infections.6
Increased incidence of serious infection and neutropenia observed with concomitant use of etanercept (another TNF blocking agent) and anakinra (a human interleukin-1 receptor antagonist).1 5 Increased incidence of infection and serious infection reported with concomitant use of a TNF blocking agent and abatacept.1 23 (See Specific Drugs and Laboratory Tests under Interactions.)
Malignancies and Lymphoproliferative Disorders
Lymphoma and other malignancies (some fatal) reported during postmarketing surveillance in children and adolescents receiving TNF blocking agents, particularly in those receiving other immunosuppressive agents (e.g., azathioprine, methotrexate) concomitantly.1 9 Malignancies included lymphomas (about 50% of the cases) (e.g., Hodgkin's disease, non-Hodgkin's lymphoma) and various other malignancies (e.g., leukemia, melanoma, solid organ cancers), including rare malignancies usually associated with immunosuppression and malignancies not usually observed in children and adolescents (e.g., leiomyosarcoma, hepatic malignancies, renal cell carcinoma).1 9 Median time to occurrence was 30 months (range: 1–84 months) after the initial TNF blocking agent dose.1 FDA has concluded that there is an increased risk of malignancy with TNF blocking agents in children and adolescents; however, the strength of the association is not fully characterized.9
In controlled studies, lymphoma was reported more frequently in patients receiving certolizumab pegol or other TNF blocking agents than in control patients.1 Patients with Crohn's disease, rheumatoid arthritis, and other chronic inflammatory diseases, especially those with highly active disease and/or chronic exposure to immunosuppressive therapies, may be at increased risk of lymphoma.1 9
In clinical studies of certolizumab pegol, rate of malignancies other than nonmelanoma skin cancer was 0.5 or 0.6 per 100 patient-years in patients receiving certolizumab pegol or placebo, respectively; however, the role of certolizumab pegol use in the development of malignancies not fully determined.1 9
Acute and chronic leukemias (some fatal) reported during postmarketing surveillance of TNF blocking agents in adults and pediatric patients, particularly in those receiving other immunosuppressive agents concomitantly.1 9 Leukemia (most commonly acute myeloid leukemia, chronic lymphocytic leukemia, and chronic myeloid leukemia) generally occurred during first 2 years of therapy.9 FDA has concluded that there is a possible association between TNF blocking agents and development of leukemia; interpretation of findings is complicated because patients with rheumatoid arthritis may be at increased risk for leukemia independent of any treatment with TNF blocking agents.1 9
Consider possibility of and monitor for occurrence of malignancies during and following treatment with TNF blocking agents.9
Other Warnings/Precautions
Cardiovascular Effects
Worsening CHF and new-onset CHF reported in patients receiving TNF blocking agents; certolizumab pegol not studied in patients with CHF.1 If used in patients with CHF, caution and careful monitoring recommended.1
Sensitivity Reactions
Angioedema, dyspnea, hypotension, rash, serum sickness, and urticaria reported rarely.1 If allergic reaction occur, discontinue certolizumab pegol and initiate appropriate treatment.1
Hepatitis B Virus (HBV) Reactivation
Increased risk of reactivation of HBV infection in patients who are chronic carriers of this virus (i.e., hepatitis B surface antigen-positive [HBsAg-positive]).1 5 Fatalities reported.1 Use of multiple immunosuppressive agents may contribute to HBV reactivation.1
Screen at-risk patients prior to initiation of therapy.1 Evaluate and monitor HBV carriers before, during, and for up to several months after therapy.1 Safety and efficacy of antiviral therapy for prevention of HBV reactivation not established.1 Discontinue certolizumab pegol and initiate appropriate treatment (e.g., antiviral therapy) if HBV reactivation occurs.1 Not known whether certolizumab pegol can be readministered once control of a reactivated HBV infection is achieved; caution advised in this situation.1
Nervous System Effects
New onset or exacerbation of CNS demyelinating disorders (e.g., multiple sclerosis) and peripheral demyelinating disorders (e.g., Guillain-Barré syndrome) reported rarely.a Use cautiously in patients with preexisting or recent-onset central or peripheral nervous system demyelinating disorders.a
Seizure disorder, optic neuritis, and peripheral neuropathy reported rarely.1
Hematologic Effects
Pancytopenia (including aplastic anemia),1 leukopenia, and thrombocytopenia reported rarely; causal relationship unclear.1 Use with caution in patients with a history of substantial hematologic abnormalities.a Consider discontinuing therapy if substantial hematologic abnormalities occur.1
Immunologic Reactions and Antibody Formation
Possible formation of autoimmune antibodies.1 2 3 Lupus-like syndrome reported rarely.1 Discontinue therapy if manifestations suggestive of a lupus-like syndrome occur.1
Antibodies to certolizumab pegol may develop.1 Incidence of antibody formation was lower in patients receiving concomitant therapy with other immunosuppressive agents (e.g., methotrexate) than in those not receiving immunosuppressive agents at baseline.1
Antibody formation associated with lower plasma drug concentrations and reduced efficacy in patients with rheumatoid arthritis.1 In patients with Crohn's disease, no apparent association between antibody development and efficacy or adverse events.1
Immunization
Avoid live vaccines.1 (See Interactions.)
Immunosuppression
May affect host defenses against infections and malignancies.a (See Infectious Complications and also Malignancies and Lymphoproliferative Disorders, under Cautions.) Safety and efficacy in immunosuppressed patients not evaluated.1
Psoriasis
New-onset psoriasis, including pustular and palmoplantar psoriasis, and exacerbation of existing psoriasis reported with TNF blocking agents.1 9 Onset of new cases observed weeks to years following initiation of drug.9 Some patients required hospitalization.9 Most patients experienced improvement following discontinuance of the TNF blocking agent.9 FDA has concluded that there is a possible association between use of TNF blocking agents and development of psoriasis.9
Consider possibility of and monitor for manifestations (e.g., new rash) of new or worsening psoriasis, particularly pustular and palmoplantar psoriasis.9 Consider discontinuance of certolizumab pegol if psoriasis occurs or worsens.a
