Number of Participants Reporting One or More Treatment Emergent Adverse Events
Időkeret: From Day 1 Up to Day 118
|
An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug.
A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug.

Ritchie articular index (RAI); a joint count that grades the tenderness of 26 joints on a scale of 0-3); the number of swollen joints from 44 joints (swollen44); ESR in mm/hour after 1 hour and the patient's global disease activity on a Visual Analogue Scale (VAS) of 100 mm (0=no disease activity to right end of the line 100=maximum disease activity) were used to calculate DAS44-ESR using the following formula: DAS44-ESR = 0.54*sqrt(RAI) + 0.065*(swollen44) + 0.33*ln(ESR) + 0.0072*VAS.
Lower numbers were better.
A negative change from Baseline indicated improvement.
