Boxed warning

RISK OF SERIOUS INFECTIONS Patients treated with KEVZARA are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions (5.1) , Adverse Reactions (6.1) ]. Opportunistic infections have also been reported in patients receiving KEVZARA. Most patients who developed infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Avoid use of KEVZARA in patients with an active infection. Reported infections include: Active tuberculosis, which may present with pulmonary or extrapulmonary disease. Patients should be tested for latent tuberculosis before KEVZARA use and during therapy. Treatment for latent infection should be initiated prior to KEVZARA use. Invasive fungal infections, such as candidiasis, and pneumocystis. Patients with invasive fungal infections may present with disseminated, rather than localized, disease. Bacterial, viral and other infections due to opportunistic pathogens. Closely monitor patients for signs and symptoms of infection during treatment with KEVZARA. If a serious infection develops, interrupt KEVZARA until the infection is controlled. Consider the risks and benefits of treatment with KEVZARA prior to initiating therapy in patients with chronic or recurrent infection.

Mechanism of action

Sourced from openFDA

Sarilumab binds to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R), and has been shown to inhibit IL-6-mediated signaling through these receptors. IL-6 is a pleiotropic pro-inflammatory cytokine produced by a variety of cell types including T- and B-cells, lymphocytes, monocytes, and fibroblasts.

Interleukin 6 Receptor

Indications

  • KEVZARA ® is an interleukin-6 (IL-6) receptor antagonist indicated for treatment of: adult patients with moderately to severely active rheumatoid arthritis (RA) who have had an inadequate response or intolerance to one or more disease-modifying antirheumatic drugs (DMARDs). ( 1.1 ) adult patients with polymyalgia rheumatica (PMR) who have had an inadequate response to corticosteroids or who cannot tolerate corticosteroid taper.ICD-10: M06.9

Contraindications

Dosage & administration

Sourced from openFDA

General Considerations for Administration KEVZARA initiation is not recommended in patients with ANC less than 2,000/mm 3 , platelets less than 150,000/mm 3 or liver transaminases above 1.5 times ULN. See Full Prescribing Information (FPI) for complete information. ( 2.1 ) Recommended Dosage in RA The recommended dosage is 200 mg subcutaneously, once every 2 weeks. ( 2.2 ) For RA, KEVZARA may be used as monotherapy or in combination with methotrexate (MTX) or other conventional DMARDs. ( 2.2 ) Recommended Dosage in PMR The recommended dosage is 200 mg subcutaneously, once every two weeks in combination with a tapering course of corticosteroids. ( 2.3 ) For PMR, KEVZARA can be used as monotherapy following discontinuation of corticosteroids. ( 2.3 ) Recommended Dosage in pJIA The recommended dosage is 200 mg given subcutaneously once every 2 weeks for pJIA patients who weigh 63 kg or greater using the 200 mg/1.14 mL pre-filled syringe. ( 2.4 ) For pJIA, KEVZARA can be used as monotherapy or in combination with conventional DMARDs. ( 2.4 ) Dosage Modifications for Cytopenias, Abnormal Liver Enzymes, Infections See FPI for complete information. ( 2.6 ) 2.1 General Considerations Prior to Administration Not Recommended for Concomitant Use with Biological DMARDS The concurrent use of KEVZARA with biological DMARDs such as tumor necrosis factor (TNF) antagonists, IL-1R antagonists, anti-CD20 monoclonal antibodies and selective co-stimulation modulators has not been studied.

Warnings & precautions

Sourced from openFDA

Serious Infections: Avoid KEVZARA use during an active infection. ( 5.1 ) Neutropenia, Thrombocytopenia, Elevated Liver Enzymes, Lipid Abnormalities: Monitor laboratory parameters. ( 5.2 ) Gastrointestinal (GI) Perforation: Risk may be increased with concurrent diverticulitis or concomitant use of NSAIDs or corticosteroids. Promptly evaluate acute abdominal signs or symptoms. ( 5.3 ) Hypersensitivity reactions. ( 5.5 ) Live vaccines: Avoid use with KEVZARA. ( 5.7 , 7.3 ) 5.1 Serious Infections Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens have been reported in patients receiving immunosuppressive agents including KEVZARA. Among opportunistic infections, tuberculosis, candidiasis, and pneumocystis were reported with KEVZARA. Some patients presented with disseminated rather than localized disease and were often taking concomitant immunosuppressants such as methotrexate or corticosteroids. The most frequently observed serious infections with KEVZARA in RA patients included pneumonia and cellulitis [see Adverse Reactions (6.1) ] . While not reported in KEVZARA clinical studies, other serious infections (e.g., histoplasmosis, cryptococcus, aspergillosis) have been reported in patients receiving other immunosuppressive agents for the treatment of RA. Avoid use of KEVZARA in patients with an active infection, including localized infections.

Adverse reactions

Sourced from openFDA

The following serious adverse reactions are described elsewhere in labeling: Serious infections [see Warnings and Precautions (5.1) ] Neutropenia, thrombocytopenia, elevated liver enzymes, lipid abnormalities [see Warnings and Precautions (5.2) ] Gastrointestinal perforation [see Warnings and Precautions (5.3) ] Immunosuppression [see Warnings and Precautions (5.4) ] Hypersensitivity reactions [see Warnings and Precautions (5.5) ] Most common adverse reactions are: Rheumatoid Arthritis (incidence ≥3 %): neutropenia, increased ALT, injection site erythema, upper respiratory infections and urinary tract infections. ( 6.1 ) Polymyalgia Rheumatica (incidence ≥ 5%): neutropenia, leukopenia and injection site pruritus. ( 6.1 ) Polyarticular Juvenile Idiopathic Arthritis: nasopharyngitis, neutropenia, upper respiratory tract infection and injection site erythema.

Rheumatoid Arthritis All patients in the safety data described below had moderately to severely active rheumatoid arthritis.

Use in specific populations

Sourced from openFDA

Lactation: Discontinue drug or nursing taking into consideration importance of drug to mother. ( 8.2 ) 8.1 Pregnancy Risk Summary The limited human data with KEVZARA in pregnant women are not sufficient to inform drug-associated risk for major birth defects and miscarriage. Monoclonal antibodies, such as sarilumab, are actively transported across the placenta during the third trimester of pregnancy and may affect immune response in the in utero exposed infant (see Clinical Considerations ) . From animal data, and consistent with the mechanism of action, levels of IgG, in response to antigen challenge, may be reduced in the fetus/infant of treated mothers (see Clinical Considerations and Data ) . In an animal reproduction study, consisting of a combined embryo-fetal and pre- and postnatal development study with monkeys that received intravenous administration of sarilumab, there was no evidence of embryotoxicity or fetal malformations with exposures up to approximately 84 times the maximum recommended human dose (MRHD) (see Data ) . The literature suggests that inhibition of IL-6 signaling may interfere with cervical ripening and dilatation and myometrial contractile activity leading to potential delays of parturition (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
