Boxed warning

WARNING: SERIOUS INFECTIONS and MALIGNANCY SERIOUS INFECTIONS Patients treated with CIMZIA are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions (5.1) and Adverse Reactions (6.1) ] . Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. CIMZIA should be discontinued if a patient develops a serious infection or sepsis. Reported infections include: Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease.

Patients should be tested for latent tuberculosis before CIMZIA use and during therapy. Treatment for latent infection should be initiated prior to CIMZIA use. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness.

Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria. The risks and benefits of treatment with CIMZIA should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with CIMZIA, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. [see Warnings and Precautions (5.1) and Adverse Reactions (6.1) ].

MALIGNANCY Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, of which CIMZIA is a member [see Warnings and Precautions (5.2) ]. WARNING: SERIOUS INFECTIONS and MALIGNANCY See full prescribing information for complete boxed warning. Increased risk of serious infections leading to hospitalization or death including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as histoplasmosis), and infections due to other opportunistic pathogens ( 5.1 ). CIMZIA should be discontinued if a patient develops a serious infection or sepsis ( 5.1 ). Perform test for latent TB; if…

Basis

Enter a dose to see draw volume, final concentration, and rates.

Preparation and Administration of CIMZIA Using the Lyophilized Powder for Injection CIMZIA Lyophilized powder should be prepared and administered by a health care professional. CIMZIA is provided in a package that contains everything required to reconstitute and inject the drug [see How Supplied/Storage and Handling ] .

Step-by-step preparation and administration instructions are provided below. Preparation and Storage If refrigerated, remove CIMZIA from the refrigerator and allow the vial(s) to sit at room temperature for 30 minutes before reconstituting. Do not warm the vial in any other way. Use appropriate aseptic technique when preparing and administering CIMZIA.

Reconstitute the vial(s) of CIMZIA with 1 mL of Sterile Water for Injection, USP using the 20-gauge needle provided. The sterile water for injection should be directed at the vial wall rather than directly on CIMZIA. Gently swirl each vial of CIMZIA for about one minute without shaking, assuring that all of the powder comes in contact with the Sterile Water for Injection.

The swirling should be as gentle as possible in order to avoid creating a foaming effect. Continue swirling every 5 minutes as long as non-dissolved particles are observed. Full reconstitution may take as long as 30 minutes. The final reconstituted solution contains 200 mg/mL and should be clear to opalescent, colorless to yellow liquid essentially free from particulates.

Once reconstituted, CIMZIA can be stored in the vials for up to 24 hours between 2° to 8° C (36° to 46° F) prior to injection. Do not freeze. Administration Prior to injecting, reconstituted CIMZIA should be at room temperature but do not leave reconstituted CIMZIA at room temperature for more than two hours prior to administration.

Withdraw the reconstituted solution into a separate syringe for each vial using a new 20-gauge needle for each vial so that each syringe contains the required volume of CIMZIA [see Dosage and Administration (2.1-2.7)] . Replace the 20-gauge needle(s) on the syringes with a 23-gauge(s) for administration. Inject the full contents of the syringe(s) subcutaneously , by pinching the skin of the thigh or abdomen.

Where a 400 mg dose is required, two injections are required, therefore, separate sites should be used for each 200 mg injection.

Preparation and Administration of CIMZIA Using the Prefilled Syringe After proper training in subcutaneous injection technique, a patient may self-inject with the CIMZIA Prefilled Syringe if a physician determines that it is appropriate. If refrigerated, remove the prefilled syringe from the carton and let it warm to room temperature.

Inspect the liquid in the prefilled syringe. It should be clear to opalescent and colorless to yellow and free from particulates. Discard the syringe if cloudy, discolored or contains particulates. Suitable sites for injection include the thigh or abdomen at least 2 inches away from the navel. Inject at least 1 inch from the previous site.

Do not inject into areas where the skin is tender, bruised, red or hard, or where there are scars or stretch marks. The needle shield inside the removable cap of the CIMZIA prefilled syringe contains a derivative of natural rubber latex which may cause allergic reactions and should be handled with caution by latex-sensitive individuals [see Warnings and Precautions ] .

Label text (6 paragraphs)

Laboratory Tests : May cause erroneously elevated aPTT results. ( 7.3 )

7.1 Use with Anakinra, Abatacept, Rituximab, and Natalizumab An increased risk of serious infections has been seen in clinical studies of other TNF-blocking agents used in combination with anakinra or abatacept, with no added benefit. Formal drug interaction studies have not been performed with rituximab or natalizumab. Because of the nature of the adverse events seen with these combinations with TNF blocker therapy, similar toxicities may also result from the use of CIMZIA in these combinations. There is not enough information to assess the safety and efficacy of such combination therapy.

Therefore, the use of CIMZIA in combination with anakinra, abatacept, rituximab, or natalizumab is not recommended [see Warnings and Precautions (5.8) ] .

7.2 Live Vaccines Avoid use of live (including attenuated) vaccines during or immediately prior to initiation of therapy with CIMZIA [see Warnings and Precautions (5.10) ] .

7.3 Laboratory Tests Interference with certain coagulation assays has been detected in patients treated with CIMZIA. Certolizumab pegol may cause erroneously elevated activated partial thromboplastin time (aPTT) assay results in patients without coagulation abnormalities. This effect has been observed with the PTT-Lupus Anticoagulant (LA) test and Standard Target Activated Partial Thromboplastin time (STA-PTT) Automate tests from Diagnostica Stago, and the HemosIL APTT-SP liquid and HemosIL lyophilized silica tests from Instrumentation Laboratories. Other aPTT assays may be affected as well. Interference with thrombin time (TT) and prothrombin time (PT) assays has not been observed.

There is no evidence that CIMZIA therapy has an effect on in vivo coagulation.

Contraindications

4 CONTRAINDICATIONS CIMZIA is contraindicated in patients with a history of hypersensitivity reaction to certolizumab pegol or to any of the excipients. Reactions have included angioedema, anaphylaxis, serum sickness, and urticaria [see Warnings and Precautions (5.4) ] . Serious hypersensitivity reaction to certolizumab pegol or to any of the excipients. ( 4 )

Liver injury (LiverTox)

D

Likelihood score D: Possible rare cause of clinically apparent liver injury as well as reactivation of hepatitis B.

Certolizumab pegol is a Fab fragment of a monoclonal antibody to human tumor necrosis factor alpha (TNFα) conjugated with polyethylene glycol (pegol) which has potent antiinflammatory activity and is used in the therapy of severe rheumatoid arthritis and inflammatory bowel disease. Certolizumab pegol has had limited use and has yet to be specifically linked to instances of idiosyncratic acute liver injury or reactivation of hepatitis B, but is likely to cause similar hepatic injury to what has been described for other TNFα antagonists such as infliximab and adalimumab.

ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.

Pregnancy and lactation

Pregnancy

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to CIMZIA during pregnancy. For more information, healthcare providers or patients can contact: MotherToBaby Pregnancy Studies conducted by the Organization of Teratology Information Specialists (OTIS). The OTIS AutoImmune Diseases Study at 1-877-311-8972 or visit http://mothertobaby.org/pregnancy-studies/. Risk Summary Limited data from an ongoing pregnancy exposure registry on use of CIMZIA in pregnant women are not sufficient to inform a risk of major birth defects or other adverse pregnancy outcomes.

However, certolizumab pegol plasma concentrations obtained from two studies of CIMZIA use during the third trimester of pregnancy demonstrated that placental transfer of certolizumab pegol was negligible in most infants at birth, and low in other infants at birth (see Data ) . There are risks to the mother and fetus associated with active rheumatoid arthritis or Crohn's disease. The theoretical risks of administration of live or live-attenuated vaccines to the infants exposed in utero to CIMZIA should be weighed against the benefits of vaccinations (see Clinical Considerations ) .

No adverse developmental effects were observed in animal reproduction studies during which pregnant rats were administered intravenously a rodent anti-murine TNFα pegylated Fab' fragment (cTN3 PF) similar to certolizumab pegol during organogenesis at up to 2.4 times the recommended human dose of 400 mg every four weeks. The background risk of major birth defects and miscarriage for the indicated population(s) are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2 to 4% and 15 to 20%, respectively.

Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Published data suggest that the risk of adverse pregnancy outcomes in women with rheumatoid arthritis or Crohn's disease is correlated with maternal disease activity and that active disease increases the risk of adverse pregnancy outcomes, including fetal loss, preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) and small for gestational age birth. Fetal/Neonatal Adverse Reaction Due to its inhibition of TNFα, CIMZIA administered during pregnancy could affect immune responses in the in utero -exposed newborn and infant. The clinical significance of BLQ or low…

Breastfeeding (LactMed)

Certolizumab is excreted into breastmilk in some, but not all, women in small amounts. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. Polyethylene glycol is not excreted into breastmilk. Numerous experts and professional guidelines have stated that the drug is a low risk to the nursing infant and acceptable to use during breastfeeding.- Anti-TNF agents appear to reduce the levels of tumor necrosis factor and IP-10 in the milk of mothers with inflammatory bowel disease in the early postpartum period. This reduction in TNF might lead to decreased milk production, so extra lactation support might be necessary in women taking certolizumab pegol.
