Clinical Trial Summary

This multicenter, open-label, single arm study will assess the safety and efficacy of RoActemra/Actemra (tocilizumab) in combination with methotrexate in patients with active rheumatoid arthritis who have an inadequate response to non-biologic disease-modifying antirheumatic drugs (DMARDs). Patients will receive RoActemra/Actemra 8 mg/kg intravenously every 4 weeks for a total of 6 infusions plus methotrexate 10-25 mg orally weekly. Anticipated time on study treatment is 24 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Achieving Low Disease Activity Score	Disease Activity Score using 28-Joint Count (DAS28) was calculated from the number of swollen joints and tender joints using the 28-joint count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) and global health assessment (participant-rated global assessment of disease activity using 10-mm visual analog scale [VAS]); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity. DAS28 less than or equal to (=3.2) equals (=) low disease activity, DAS28 greater than (>)3.2 to 5.1 = moderate to high disease activity.	Week 24	No
Secondary	Time to Achieve Low Disease Activity (DAS28 =3.2)	DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hour) and global health assessment (participant-rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity. DAS28 =3.2 = low disease activity; time to low disease activity was calculated as the time in weeks from the date of first infusion to the first achievement of DAS28 =3.2	Baseline, Weeks 2, 4, 8, 12, 16, 20, and 24	No
Secondary	Percentage of Participants With a Clinically Significant Improvement in DAS28 Score	DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hour) and global health assessment (participant-rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity; a clinically significant improvement in DAS28 score was defined as a reduction of at least 1.2 units.	Weeks 4, 8, 12, 16, 20 and 24	No
Secondary	Time to Clinically Significant Improvement in DAS28	DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hour) and global health assessment (participant-rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity; a clinically significant improvement is a reduction in DAS28 score of at least 1.2 units. Time to clinically significant improvement was determined in weeks from the date of first infusion to the date of first achievement of reduction of 1.2 units in DAS28.	Weeks 4, 8, 12, 16, 20 and 24	No
Secondary	Percentage of Participants Achieving DAS28 Remission (DAS28 <2.6)	DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hour) and global health assessment (participant-rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity. Remission was defined as DAS28 <2.6.	Baseline and Weeks 4, 8, 12, 16, 20, and 24	No
Secondary	Time to Achieve DAS28 Remission (DAS28 <2.6)	DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hour) and global health assessment (participant-rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity. DAS28 remission was defined as DAS28 <2.6. Time to achieve remission was calculated in weeks as the time from the date of first infusion to the date of first achieving remission.	Weeks 4, 8, 12, 16, 20 and 24	No
Secondary	Percentage of Participants With DAS28 <3.2 by Visit	DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hour) and global health assessment (participant-rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity. DAS28 =3.2 = low disease activity, DAS28 >3.2 to 5.1 = moderate to high disease activity.	Baseline and Weeks 4, 8, 12, 16, 20, and 24	No
Secondary	Percentage of Participants Achieving American College of Rheumatology (ACR) 20%, 50%, and 70% Improvement (ACR20, ACR50, or ACR70) Response	ACR20/50/70 response was defined as =20%, =50%, or =70% improvement, respectively, in swollen/tender joint count (66 joints assessed for swelling and 68 joints assessed for tenderness) as well as improvement in at least 3 of the 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the health assessment questionnaire [HAQ]); and acute phase response: C-reactive protein (CRP) or ESR.	Week 24	No
Secondary	Erythrocyte Sedimentation Rate	Erythrocyte Sedimentation rate was measured in mm/hour and was used to determine the acute phase response. Lower ESR values indicate reduction in disease activity; normal reference range: 0-20 mm/hr.	Baseline, Weeks 4, 8, 12, 16, 20, and 24	No
Secondary	C-Reactive Protein Levels	CRP levels were measured in milligrams/liter (mg/L) and were used to determine the acute phase response. A reduction in CRP levels is considered an improvement; normal reference range =10 mg/L.	Baseline, Weeks 4, 8, 12,16, 20, and 24	No
