GDC-0853 (200mg BID) Cohort 1
Participants received GDC-0853 orally twice daily (BID) for 52 weeks, after completing 12 weeks in Cohort 1 of Study GA29350. Cohort 1 participants in GA29350 were enrolled with moderate to severe active Rheumatoid Arthritis (RA) and an inadequate response to previous methotrexate (MTX) therapy and then randomized to 12 weeks of GDC-0853 (50 mg daily, 150 mg daily, or 200 mg BID), adalimumab, or placebo.
GDC-0853 (200mg BID) Cohort 2
Participants received GDC-0853 orally twice daily (BID) for 52 weeks, after completing 12 weeks in Cohort 2 of Study GA29350. Cohort 2 participants in GA29350 were enrolled with moderate to severe active Rheumatoid Arthritis (RA) and an inadequate response to one or two tumor necrosis factor (TNF) inhibitors and methotrexate (MTX) therapy, and then randomized to 12 weeks of GDC-0853 (200 mg BID) or placebo.

PRIMARY outcome

Timeframe: Day 1 up until 8 weeks after the last dose of study drug (up to 1 year, 2 months)

Population: The Safety-Evaluable Population was defined as all participants who received any study drug and had at least one assessment of safety.

An Adverse Event (AE) 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.

Population: The Intent-To-Treat (ITT) Population was defined as all eligible participants enrolled in this OLE study. Number of participants for whom data were actually collected is indicated for each time point.

The DAS28 score is a measure of the patient's disease activity calculated using the tender joint count (TJC) \[28 joints\], swollen joint count (SJC) \[28 joints\], patient's global assessment of disease activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\] and the erythrocyte sedimentation rate (ESR) for a total possible score of 0 to approximately 10. Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. DAS28 Remission is defined as a DAS28 score \< 2.6.

The DAS28 score is a measure of the patient's disease activity calculated using the tender joint count (TJC) \[28 joints\], swollen joint count (SJC) \[28 joints\], patient's global assessment of disease activity \[visual analog scale: 0=no disease activity to 100=maximum disease activity\] and the erythrocyte sedimentation rate (ESR) for a total possible score of 0 to approximately 10. Scores below 2.6 indicate best disease control and scores above 5.1 indicate worse disease control. DAS28 Remission is defined as a DAS28 score \< 2.6.

Simplified Disease Activity Index (SDAI) is the numerical sum of five outcome parameters: TJC and SJC (based on a 28-joint assessment), PtGA and PhGA (based on 0-10 cm VAS, where 0 = no disease activity and 10 = worst disease activity), and CRP. SDAI total score ranges from 0 (no disease activity) to 86 (maximal disease activity), where higher scores represents higher disease activity. The SDAI =\< 3.3 indicates disease remission, \> 3.4 to 11 indicates low disease activity, \> 11 to 26 indicates moderate disease activity, and \> 26 indicates high disease activity

Population: The Intent-To-Treat (ITT) Population was defined as all eligible participants enrolled in this OLE study. Number of participants for whom data were actually collected is indicated for each time point.

CDAI was derived as the sum of the following: tender joint count (TJC), swollen joint count (SJC), participant global assessment (PGA) of disease activity, and physician assessment of disease activity. TJC and SJC were taken as the number of tender and swollen joints, respectively, out of 28 assessed joints. PGA and physician assessment of disease activity were scored 0-100 millimeters (mm) and rounded to the nearest centimeter (cm) on a visual analog scale (VAS), where higher scores indicate greater perceived disease activity. The total CDAI score range was 0-76, where higher scores indicate increased disease activity. Change from baseline at a particular time point was calculated among patients with data available at both baseline and the time point of interest. Negative values indicate improvement/reduction in RA disease activity.

Participant-assessed arthritis pain was scored on a 100-mm VAS, where the distance from 0 mm represented the participant's self evaluation of arthritis pain (0 mm=none; 100 mm=very severe). Change from baseline at a particular time point was calculated among patients with data available at both baseline and the time point of interest, where negative change indicated a decrease in participant-assessed arthritis pain.

The Stanford Health Assessment Questionnaire disability index is a patient-reported outcome used to assess difficulty in performing activities of daily living. It consists of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. To respond to each question, a four-level response with higher scores showing larger functional limitations, was chosen. Scoring is as follows with respect to performance of participant's everyday activities: 0 (equals)=without difficulties; 1= with some difficulties; 2=with great difficulties; and 3=unable to perform these actions at all. The composite HAQ-DI score is the mean of the eight domain scores and the score ranges from 0 (no functional impairment) to 3 (maximum functional impairment). A negative change from baseline indicates improvement.

The 36-Item Short Form Health Survey (SF-36v2) is a questionnaire used to assess functional health and well-being and consists of eight domains: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional and Mental Health. The SF-36v2 is summarized into Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. The PCS and MCS scores range from 0 to 100, with 0=worst score (or quality of life) and 100=best score. A positive change from baseline indicates improvement.

The FACIT-Fatigue Scale consists of 13 items designed to measure the degree of fatigue experienced by the patient in the previous 7 days. For each question, there are five possible responses: 0 (not at all), 1 (a little bit), 2 (somewhat), 3 (quite a bit), 4 (very much). A total fatigue score is calculated by summing all items, and possible total scores range from 0 (maximum fatigue) to 52 (no fatigue). A positive change from baseline indicates an improvement in the patient's fatigue (less fatigue).

GDC-0853 (200mg BID) Cohort 1
n=410 participants at risk
Participants received GDC-0853 orally twice daily (BID) for 52 weeks, after completing 12 weeks in Cohort 1 of Study GA29350. Cohort 1 participants in GA29350 were enrolled with moderate to severe active Rheumatoid Arthritis (RA) and an inadequate response to previous methotrexate (MTX) therapy and then randomized to 12 weeks of GDC-0853 (50 mg daily, 150 mg daily, or 200 mg BID), adalimumab, or placebo.
GDC-0853 (200mg BID) Cohort 2
n=86 participants at risk
Participants received GDC-0853 orally twice daily (BID) for 52 weeks, after completing 12 weeks in Cohort 2 of Study GA29350. Cohort 2 participants in GA29350 were enrolled with moderate to severe active Rheumatoid Arthritis (RA) and an inadequate response to one or two tumor necrosis factor (TNF) inhibitors and methotrexate (MTX) therapy, and then randomized to 12 weeks of GDC-0853 (200 mg BID) or placebo.
