Long-term Safety and Tolerability Study of Adalimumab in Subjects With Crohn's Disease

Clinical remission was defined as a Crohn's Disease Activity Index (CDAI) score of < 150. The CDAI is a weighted composite score of 8 clinical factors measured over a 1-week period. A lower CDAI score indicates lesser disease severity.

A CR-100 is a decrease from baseline in CDAI score of 100 or more points. The CDAI is a weighted composite score of 8 clinical factors measured over a 1-week period. A lower CDAI score indicates lesser disease severity.

A CR-70 is a decrease from baseline in CDAI score of 70 or more points. The CDAI is a weighted composite score of 8 clinical factors measured over a 1-week period. A lower CDAI score indicates lesser disease severity.

Steroid-free remission was achieved if the subject stopped taking steroids before the visit and had a Crohn's Disease Activity Index (CDAI) score of <150. The CDAI is a weighted composite score of 8 clinical factors measured over a 1-week period. A lower CDAI score indicates lesser disease severity.

Steroid-free CR-100 was achieved if the subject stopped taking steroids before the visit and had a decrease from baseline in CDAI score of 100 or more points at that visit. The CDAI is a weighted composite score of 8 clinical factors measured over a 1-week period. A lower CDAI score indicates lesser disease severity.

Fistula remission was defined as the absence of draining fistulas in subjects with fistula present at the preceding study's baseline visit.

Serious infections are infectious adverse events that meet at least one criterion for a serious adverse event (e.g., death, life threatening event, hospitalization) including tuberculosis (TB), bacterial sepsis, invasive fungal infections (e.g., histoplasmosis), and infections due to other opportunistic pathogens.

An injection site reaction is any adverse event corresponding to a preferred term beginning with "injection site" excluding injection site arthritis, injection site movement impairment, injection site photosensitivity, injection site joint effusion, injection site joint inflammation, injection site scab, injection site joint pain, or injection site laceration.
