E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To evaluate the efficacy and safety of GDC-0853 compared with placebo used in combination with stable doses of methotrexate (MTX) in patients (Pts) with active RA who have had an inadequate response (IR) to MTX and are naive to tumour necrosis factor (TNF) therapy |
|
E.2.2 | Secondary objectives of the trial |
•To evaluate the efficacy of GDC-0853
-Compared with adalimumab used in combination with stable doses of
MTX in Pts with active RA who have had IR to MTX and who are naive to
TNF therapy
-Compared with placebo used in combination with stable doses of MTX in
Pts with active RA who have had IR or intolerance to 1 or 2 TNF
inhibitors
-Over time with multiple standardized assessments
•To assess efficacy based on the individual components of the American
College of Rheumatology (ACR) response criteria for RA
•To assess Disease Activity Score 28 remission (< 2.6), Low-disease
activity (< 3.2) state, and remission based on Clinical Disease Activitiy
Index ; ACR/ EULAR Boolean and Simplified Disease Activity Index
•To evaluate the effect of GDC-0853 compared with placebo on healthrelated
quality of life and on fatigue
•To evaluate the safety and pharmacokinetics of GDC-0853 in
combination with MTX in Pts with active RA
