What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Analysis of Serum AUC0-last of Rituximab During the 1st Course of the Main Study Period (Over the First 24 Weeks) (ANCOVA)
Time Frame: over the first 24 weeks

For evaluation of pharmacokinetics (PK), the primary endpoint was defined as the analysis of serum AUC0-last, AUC0-inf and Cmax of rituximab during the 1st course of the Main Study Period (over the first 24 weeks). During the 1st course of the Main Study Period, blood samples for PK analysis were collected every week from Week 0 to Week 4, every 4 weeks from Week 4 to Week 16, followed by Week 24.

AUC0-last: Area under the concentration-time curve from time to the last measurable concentration over both doses of the 1st course
over the first 24 weeks
Analysis of Serum AUC0-inf of Rituximab During the 1st Course of the Main Study Period (Over the First 24 Weeks) (ANCOVA)
Time Frame: at Week 24 of the Main Study Period

For evaluation of PK, the primary endpoint was defined as the analysis of serum AUC0-last, AUC0-inf and Cmax of rituximab during the 1st course of the Main Study Period (over the first 24 weeks). During the 1st course of the Main Study Period, blood samples for PK analysis were collected every week from Week 0 to Week 4, every 4 weeks from Week 4 to Week 16, followed by Week 24.

AUC0-inf: Area under the concentration-time curve from time 0 extrapolated to infinity over both doses of the 1st course
at Week 24 of the Main Study Period
Analysis of Serum Cmax of Rituximab During the 1st Course of the Main Study Period (Over the First 24 Weeks) (ANCOVA)
Time Frame: at Week 24 of the Main Study Period

For evaluation of pharmacokinetics (PK), the primary endpoint was defined as the analysis of serum AUC0-last, AUC0-inf and Cmax of rituximab during the 1st course of the Main Study Period (over the first 24 weeks). During the 1st course of the Main Study Period, blood samples for PK analysis were collected every week from Week 0 to Week 4, every 4 weeks from Week 4 to Week 16, followed by Week 24.

Cmax: Observed maximum concentration after the seocnd infusion of the 1st course
at Week 24 of the Main Study Period
Analysis of Change From Baseline of DAS28 (CRP) at Week 24 (ANCOVA)
Time Frame: at Week 24 of the Main Study Period
For evaluation of efficacy, the primary endpoint was defined as the analysis of change from baseline in disease activity measured by disease activity score 28 (DAS 28) C-reactive protein (CRP) at Week 24 between 2 treatment groups, CT-P10 and reference products (combined Rituxan and MabThera) groups. During the 1st course of the Main Study Period, DAS28 was assessed every 4 weeks from Week 0 to Week 24. DAS28 (CRP) was calculated using the following formula: DAS28 (CRP) = 0.56 X SQRT(TJC28) + 0.28 X SQRT(SJC28) + 0.36 X ln(CRP+1) + 0.014 X GH on VAS + 0.96. DAS28 (CRP) provides a number on a scale from 0 to 10 with higher values indicating greater RA disease activity.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

Time Frame: at Week 24 of the Main Study Period
For evaluation of efficacy, the secondary endpoint was defined as descriptive statistics of mean change from baseline in disease activity measured by DAS 28 (CRP) and DAS28 erythrocyte sedimentation rate (ESR) at Week 24 (efficacy population) and Week 48 (efficacy population - 2nd treatment course in Main Study Period subset) for the Main Study Period between 2 treatment groups, CT-P10 and reference products (combined Rituxan and MabThera) groups. DAS28 was assessed every 4 weeks from Week 0 to Week 24 during the 1st treatment course of the Main Study Period and every 8 weeks from Week 24 to Week 48 during the 2nd treatment course of the Main Study Period. DAS28 (CRP) was calculated using the following formula: DAS28 (CRP) = 0.56 X SQRT(TJC28) + 0.28 X SQRT(SJC28) + 0.36 X ln(CRP+1) + 0.014 X GH on VAS + 0.96.
