Adalimumab

Recombinant monoclonal IgG1 antibody, consisting only of human sequences, against tumor necrosis factor alpha (TNF-α) with specific binding to TNF-alpha and without affinity to other members of the human TNF family. Pharmacologically the antibody belongs to the group of "immune response modifiers".

Neutralization of the biological function of TNF-alpha through highly specific binding to the TNF-alpha molecules and inhibition of interaction with the cell-bound p55 and p75 TNF receptors.

Secondarily, the production and secretion of IL-1 and IL-6 as well as leukocyte migration and expression of adhesion molecules are inhibited.

Moderate to severe active rheumatoid arthritis in adults with treatment failure to other therapies including methotrexate.

Active & progressive psoriatic arthritis in adults who have responded inadequately to therapy with basic disease-modifying agents. Primarily used in combination therapy with methotrexate (to prevent the formation of autoantibodies against adalimumab), can also be used as monotherapy if MTX is intolerable.

It has now also been approved as a first-line therapy for psoriasis.

Plaque psoriasis

Adalimumab can also be used in children with severe plaque psoriasis who have not responded adequately to methotrexate.

Off label use: Acrodermatitis continua suppurativa (see there)

Frequent local reactions at the injection site such as redness, pain, pruritus.

Occasionally infections of the respiratory system as well as urinary tract infections, herpes simplex, nausea, diarrhea, headache.

Immunogenicity: Anti-Adalimiúmab antibodies occur in 6-50% of patients. However, this does not rule out a good clinical response (Hsu L et al. (2014).

^Humira®

Please note! Contraception for women during therapy until at least 5 months after the end of therapy and for men during use until 70 days after the last adalimumab injection!

New study data indicate that adalimumab leads to a significant improvement in disease symptoms in patients with moderate to severe psoriasis. Regular use of the fully human monoclonal antibody can also reduce the risk of recurrence.

A biosimilar has been available since 2018 (Hexal/Hyrimoz®)
