The usual adult dose of Humira used to treat Crohn’s disease includes an initial dose of 160mg of adalimumab (recombinant) administered subcutaneously (SC) followed by 80mg SC two weeks after the initial dose, and then after four weeks of the initial dose.
Eventually, 40mg SC is given every two weeks thereafter.
However, during the course, some patients became less responsive to their treatment, necessitating therapy aimed at ‘long-term maintenance of remission’, the aim of treatment for Crohn’s disease.
A Japanese clinical study recently revealed the efficacy of an increased dose of 80mg every two weeks in patients who become less responsive to the traditional dose.
