Pronunciation:

(a da LIM yoo mab)

U.S. Brand Names:

Humira®

Synonyms:

Antitumor Necrosis Factor Apha (Human); D2E7; Human Antitumor Necrosis Factor-alpha

Generic Available:

Use:

Treatment of active rheumatoid arthritis (moderate to severe) in patients with inadequate response to one or more disease-modifying antirheumatic drugs (DMARDs)

Pregnancy Risk Factor:

Pregnancy Implications:

Teratogenic effects were not observed in animal studies, however, there are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if clearly needed. A pregnancy registry has been established to monitor outcomes of women exposed to adalimumab during pregnancy (877-311-8972).

Lactation:

Excretion in breast milk unknown/not recommended

Contraindications:

Hypersensitivity to adalimumab or any component of the formulation

Warnings/Precautions:

Tuberculosis (disseminated or extrapulmonary) has been reactivated while on adalimumab. Most cases have been reported within the first 8 months of treatment. Patients should be evaluated for latent tuberculosis infection with a tuberculin skin test prior to therapy. Treatment of latent tuberculosis should be initiated before adalimumab is used. Use caution with chronic infection, history of recurrent infection, or predisposition to infection. Do not give to patients with a clinically-important, active infection. Adalimumab may affect defenses against infections and malignancies; serious infections (including sepsis and fatal infections) have been reported in patients receiving TNF-blocking agents, including adalimumab. Many of the serious infections have occurred in patients on concomitant immunosuppressive therapy. Other opportunistic infections (Histoplasma, Aspergillus, and Nocardia) have occurred during therapy. Use caution in patients who have resided in regions where histoplasmosis is endemic. Patients who develop a new infection while undergoing treatment with adalimumab should be monitored closely. If a patient develops a serious infection or sepsis, adalimumab should be discontinued. Impact on the development and course of malignancies is not fully defined. Rare cases of lymphoma have also been reported in association with adalimumab.

May exacerbate pre-existing or recent-onset demyelinating CNS disorders. Use caution in patients with CHF. Patients should be brought up to date with all immunizations before initiating therapy. No data are available concerning the effects of adalimumab on vaccination. Live vaccines should not be given concurrently. No data are available concerning secondary transmission of live vaccines in patients receiving adalimumab. Rare cases of pancytopenia (including aplastic anemia) have been reported with TNF-blocking agents; with significant hematologic abnormalities, consider discontinuing therapy. Safety and efficacy have not been established in pediatric patients.

Overdosage/Toxicology:

Doses of up to 10 mg/kg have been tolerated in clinical trials. In case of overdose, treatment should be symptomatic and supportive.

Drug Interactions:

Anakinra: Concomitant use may increase risk of infections; not recommended.

Vaccines, live: Concomitant use has not be studied; currently recommended not to administer live vaccines during adalimumab therapy.

Stability:

Store under refrigeration at 2°C to 8°C (36°F to 46°F); do not freeze, protect from light

Mechanism of Action:

Adalimumab is a recombinant monoclonal antibody that binds to human tumor necrosis factor alpha (TNF-alpha) receptor sites, thereby interfering with endogenous TNF-alpha activity. Elevated TNF levels in the synovial fluid are involved in the pathologic pain and joint destruction in rheumatoid arthritis. Adalimumab decreases signs and symptoms of rheumatoid arthritis and inhibits progression of structural damage.

Pharmacodynamics/Kinetics:

Distribution: Vd: 4.7-6 L; Synovial fluid concentrations: 31% to 96% of serum

Bioavailability: Absolute: 64%

Half-life elimination: Terminal: ~2 weeks (range 10-20 days)

Time to peak, serum: SubQ: 131 ± 56 hours

Excretion: Clearance increased in the presence of anti-adalimumab antibodies; decreased in patients 40 to >75 years

Dosage:

SubQ: Adults: Rheumatoid arthritis: 40 mg every other week; may be administered with other DMARDs; patients not taking methotrexate may increase dose to 40 mg/weekly

Administration:

For SubQ injection; rotate injection sites. Do not use if solution is discolored. Do not administer to skin which is red, tender, bruised, or hard.

Monitoring Parameters:

Improvement of symptoms; signs of infection; place and read PPD before initiation

Patient Education:

Inform prescriber of all prescriptions, OTC medications, or herbal products you are taking, allergies, history of tuberculosis, or any kind of infection you have. Do not take any new medication during therapy without consulting prescriber. If self-administered, follow directions for injection and needle/syringe disposal exactly. Do not have any vaccinations while using this medication without consulting prescriber first. May cause headache or dizziness (use caution when driving or engaged in potentially hazardous tasks); if persistent, consult prescriber for approved analgesic. Report persistent fever, respiratory tract infection, unhealed or infected wounds, urinary tract infection, or flu-like symptoms. Stop drug and report immediately persistent nausea, abdominal pain; numbness or tingling; problems with vision; weakness in legs; chest pains, respiratory difficulty; joint pain; skin rash; and redness, swelling, or pain at injection site. Pregnancy/breast-feeding precautions: Consult prescriber if you are or intend to become pregnant. Breast-feeding is not recommended.
