Adalimumab

May rarely cause hypersensitivity, anaphylaxis, anaphylactoid reactions, or angioneurotic edema; medications for the treatment of hypersensitivity reactions should be available for immediate use.

Positive antinuclear antibody titers have been detected in patients (with negative baselines). Rare cases of autoimmune disorder, including lupus-like syndrome, have been reported; monitor and discontinue if symptoms develop.

Rare cases of new-onset or exacerbation of demyelinating disorders (eg, multiple sclerosis, optic neuritis, peripheral demyelinating disease, including Guillain-Barré syndrome) have been reported; there is a known association between intermediate uveitis and central demyelinating disorders. Consider discontinuing use in patients who develop peripheral or central nervous system demyelinating disorders during treatment. Use with caution in patients with preexisting or recent onset central or peripheral nervous system demyelinating disorders.

Worsening and new-onset heart failure (HF) has been reported with adalimumab and other TNF blockers. Use with caution in patients with HF or decreased left ventricular function. In a scientific statement from the American Heart Association, TNF blockers have been determined to be agents that may either cause direct myocardial toxicity or exacerbate underlying myocardial dysfunction (magnitude: major) (AHA [Page 2016]).

Rare cases of pancytopenia and aplastic anemia have been reported with TNF-blockers. Patients must be advised to seek medical attention if they develop signs and symptoms suggestive of blood dyscrasias; discontinue if significant hematologic abnormalities are confirmed. Use with caution in patients with a history of significant hematologic abnormalities.

Rare reactivation of hepatitis B (HBV) has occurred in chronic carriers of the virus, usually in patients receiving concomitant immunosuppressants (some have been fatal); evaluate for HBV prior to initiation in all patients. Monitor during and for several months following discontinuation of treatment in HBV carriers; interrupt therapy if reactivation occurs and treat appropriately with antiviral therapy; if resumption of therapy is deemed necessary, exercise caution and monitor patient closely.

Patients receiving adalimumab are at increased risk for serious infections which may result in hospitalization and/or fatality; infections usually developed in patients receiving concomitant immunosuppressive agents (eg, methotrexate, corticosteroids) and may present as disseminated (rather than local) disease. Active tuberculosis (including reactivation of latent tuberculosis), invasive fungal (including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, histoplasmosis, and pneumocystosis) and bacterial, viral or other opportunistic infections (including legionellosis and listeriosis) have been reported. Monitor closely for signs/symptoms of infection during and after treatment. Discontinue for serious infection or sepsis. Consider risks versus benefits prior to initiating therapy in patients with chronic or recurrent infection. Consider empiric antifungal therapy in patients who are at risk for invasive fungal infections who develop severe systemic illness. Caution should be exercised when considering use in the elderly, patients with a history of an opportunistic infection, patients taking concomitant immunosuppressants (eg, corticosteroids, methotrexate), or in patients with conditions that predispose them to infections (eg, advanced or poorly controlled diabetes) or residence/travel in areas of endemic tuberculosis or mycoses (blastomycosis, coccidioidomycosis, histoplasmosis), or with latent infections. Do not initiate adalimumab in patients with an active i

Lymphoma and other malignancies (some fatal) have been reported in children and adolescents receiving TNF-blocking agents, including adalimumab. Half of the malignancies reported in children and adolescents were lymphomas (Hodgkin and non-Hodgkin) while other cases varied and included rare malignancies usually associated with immunosuppression and malignancies not typically observed in this population. Most patients were receiving concomitant immunosuppressants. [US Boxed Warning]: Hepatosplenic T-cell lymphoma (HSTCL), a rare T-cell lymphoma, has been reported (some fatal) primarily in patients with Crohn disease or ulcerative colitis treated with adalimumab and who received concomitant azathioprine or mercaptopurine; reports occurred predominantly in adolescent and young adult males. The impact of adalimumab on the development and course of malignancy is not fully defined. Compared to the general population, an increased risk of lymphoma has been noted in clinical trials; however, rheumatoid arthritis alone has been previously associated with an increased rate of lymphoma and leukemia. A higher incidence of nonmelanoma skin cancers was noted in adalimumab-treated patients (0.7/100 patient years), when compared to the control group (0.2/100 patient years).

[US Boxed Warnings]: Active tuberculosis (disseminated or extrapulmonary), including reactivation of latent tuberculosis, has been reported in patients receiving adalimumab. Evaluate patients for tuberculosis risk factors and latent tuberculosis infection (with a skin test) prior to and during therapy. Treatment for latent tuberculosis should be initiated before use. Patients with initial negative tuberculin skin tests should receive continued monitoring for tuberculosis during and after treatment. Consider antituberculosis treatment if an adequate course of treatment cannot be confirmed in patients with a history of latent or active tuberculosis or with risk factors despite negative skin test. Some patients who tested negative prior to therapy have developed active infection; tests for latent tuberculosis infection may be falsely negative while on adalimumab therapy. Use with caution in patients who have traveled to or resided in regions where tuberculosis is endemic. Monitor for signs and symptoms of tuberculosis in all patients. Concurrent drug therapy issues:

Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information. Special populations:

Infection and malignancy has been reported at a higher incidence; use caution in elderly patients.

Malignancies have been reported among children and adolescents.

Limited experience with patients undergoing surgical procedures while on therapy; consider long half-life with planned procedures. Monitor closely for infection. Dosage form specific issues:

The packaging (needle cover of prefilled syringe and autoinjector) may contain latex.

Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer's labeling. Other warnings/precautions:

Patients should be brought up to date with all immunizations before initiating therapy; live vaccines should not be given concurrently. There are no data available concerning the effects of therapy on vaccination or secondary transmission of live vaccines in patients receiving therapy.
