Overview
Brief Summary
This is a multicenter, Phase II, randomized, double-blind, placebo-controlled, active comparator (Cohort 1 only), parallel-group, dose-ranging study to evaluate the efficacy and safety of GDC-0853 in participants with moderate to severe active RA and an inadequate response to previous methotrexate (MTX) therapy (Cohort 1) or MTX and tumor necrosis factor (TNF) therapy who may have also had exposure to no more than one non-TNF inhibitor biologic (Cohort 2).

Primary Outcomes
Percentage of Participants With Adverse Events
Time Frame: Day 1 up to 8 weeks after last dose (up to Week 20)
An Adverse event was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug. Preexisting conditions that worsened during the study were reported as adverse events. A SAE was any experience that suggested a significant hazard, contraindication, side effect or precaution that: resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was medically significant.
