Primary Outcome Measures:
  • Number of Participants Meeting American College of Rheumatology 20% (ACR20) Response Criteria at Week 520 [ Time Frame: Week 520 ]
    ACR20 response criteria were: >=20% improvement in tender joint count; >=20% improvement in swollen joint count; and >=20% improvement in at least 3 of the 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response). All improvements were assessed relative to the baseline of the prior study.

  • Number of Participants Meeting American College of Rheumatology 20% (ACR20) Response Criteria at Week 260 [ Time Frame: Week 260 ]
    ACR20 response criteria were: >=20% improvement in tender joint count; >=20% improvement in swollen joint count; and >=20% improvement in at least 3 of the 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response). All improvements were assessed relative to the baseline of the prior study.

  • Number of Participants Meeting American College of Rheumatology 50% (ACR50) Response Criteria at Week 520 [ Time Frame: Week 520 ]
    ACR50 response criteria were: >=50% improvement in tender joint count; >=50% improvement in swollen joint count; and >=50% improvement in at least 3 of the 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response). All improvements were assessed relative to the baseline of the prior study.

  • Number of Participants Meeting American College of Rheumatology 50% (ACR50) Response Criteria at Week 260 [ Time Frame: Week 260 ]
    ACR50 response criteria were: >=50% improvement in tender joint count; >=50% improvement in swollen joint count; and >=50% improvement in at least 3 of the 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response). All improvements were assessed relative to the baseline of the prior study.

  • Number of Participants Meeting American College of Rheumatology 70% (ACR70) Response Criteria at Week 520 [ Time Frame: Week 520 ]
    ACR70 response criteria were: >=70% improvement in tender joint count; >=70% improvement in swollen joint count; and >=70% improvement in at least 3 of the 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response). All improvements were assessed relative to the baseline of the prior study.

  • Number of Participants Meeting American College of Rheumatology 70% (ACR70) Response Criteria at Week 260 [ Time Frame: Week 260 ]
    ACR70 response criteria were: >=70% improvement in tender joint count; >=70% improvement in swollen joint count; and >=70% improvement in at least 3 of the 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response). All improvements were assessed relative to the baseline of the prior study.

  • Number of Participants in Clinical Remission (Based on Modified Disease Activity Score) at Week 520 [ Time Frame: Week 520 ]
    Clinical remission on modified Disease Activity Score (DAS28) was a value <2.6; >=2.6 to <=3.2 indicated low disease activity; >3.2 to <=5.1 indicated moderate disease activity; and >5.1 indicated high disease activity. DAS28 score is calculated using the number of tender joints and swollen joints (out of 28 each), patient global assessment of disease activity, and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response).

  • Number of Participants in Clinical Remission (Based on Modified Disease Activity Score) at Week 260 [ Time Frame: Week 260 ]
    Clinical remission on modified Disease Activity Score (DAS28) was a value <2.6; >=2.6 to <=3.2 indicated low disease activity; >3.2 to <=5.1 indicated moderate disease activity; and >5.1 indicated high disease activity. DAS28 score is calculated using the number of tender joints and swollen joints (out of 28 each), patient global assessment of disease activity, and C-reactive protein (a laboratory marker of inflammation that is sensitive to acute changes in inflammatory response).

  • Change From Baseline in the Disability Index of the Health Assessment Questionnaire (HAQ) at Week 520 [ Time Frame: Baseline of prior Phase 1, 2, or 3 adalimumab study and Week 520 ]
    The HAQ-DI is a measure of disability that ranges from 0 to 3. Decrease in score indicates improvement in physical function; a decrease of 0.22 or greater from Baseline score is clinically significant. Participants assessed their ability to perform at least 6 of the following 8 specific tasks (1. dress/groom; 2. arise; 3. eat; 4. walk; 5. reach; 6. grip; 7. maintain hygiene; 8. maintain daily activity) over the past week by marking their response on a questionnaire. Possible responses/scores included the following: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). The 8 task scores are added and the sum is divided by the number of tasks assessed (range = 6 to 8). This yields a HAQ-DI score of 0 to 3.

Secondary Outcome Measures:
  • Reported Adverse Events [ Time Frame: Duration of study (up to 520 weeks [10 years]) ]
    Adverse events were collected during the course of the study (after the first adalimumab injection in this continuation study DE020 through 70 days after the last adalimumab injection) for all participants who received at least 1 dose of open-label adalimumab in the continuation study (Full Analysis Set). The number of participants experiencing any adverse event (serious and non-serious) are summarized. See the Reported Adverse Events section for details.


Enrollment: 846
Study Start Date: July 2000
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Adalimumab
Open-label adalimumab 40 mg
Biological: Adalimumab
Subcutaneous injection of 40 mg adalimumab every other week (eow) or monthly for up to 520 weeks (10 years)
Other Name: Humira, ABT-D2E7

Detailed Description:
Study DE020 was a multicenter, open-label continuation study for patients with rheumatoid arthritis who had participated in a prior Phase 1, 2, or 3 adalimumab study in the United States or Canada, had a favorable safety and efficacy profile when treated with adalimumab, and met the eligibility criteria for the continuation study. Participants received subcutaneous injections of adalimumab every other week (eow) or monthly based on the adalimumab regimen received in the prior study (i.e., participants who received monthly dosing in the prior study began the continuation study on monthly dosing; all other participants began adalimumab dosing at eow intervals). Participants who maintained an American College of Rheumatology 50% (ACR50) response for 2 consecutive visits could have their dosing interval lengthened to a monthly dosing schedule. Safety and efficacy data were collected over 520 weeks (10 years). Both safety and efficacy data were analyzed using all participants who received at least 1 dose of open-label adalimumab in the 10-year continuation study DE020 (the Full Analysis Set, n=846). Three patients who entered the continuation study but were never dosed were excluded from all analyses.
