| Mean Change From Baseline Through Week 12 in Duration (Minutes) of Morning Stiffness | The Investigator asked participants about the duration of their morning stiffness (in minutes) in and around the joints and recorded the duration. The Investigator asked the participants about duration of morning stiffness on the day prior to the study visit to capture actual symptoms. If morning stiffness duration was longer than 12 hours (720 minutes), it was truncated to 720 minutes for statistical presentations and analyses. | Baseline, Weeks 4, 8, 12 | 
| Mean Change From Baseline to Week 12 in Medical Outcomes Study 36-Item Short Form (SF-36) Health Survey Physical Component Summary (PCS) and Mental Component Summary (MCS) Scores | The SF-36 is a health-related survey that assesses participant's quality of life and consists of 36 questions covering 8 health domains (physical functioning, bodily pain, role limitations due to physical problems and also emotional problems, general health, mental health, social functioning and vitality) and 2 component scores (PCS and MCS). The PCS score consisted of physical functioning, bodily pain, role-physical, and general health scales. The MCS score consisted of social functioning, vitality, mental health, and role-emotional scales. Both PCS and MCS range from 0-100 with higher scores indicating better health or functioning. | Baseline, Week 12 | 
| Mean Change From Baseline to Week 12 in Brief Pain Inventory Modified Short Form (BPI-sf Modified) Worst-Pain-in-the Past-24-hours Item Score | The BPI-sf modified is a self-administered questionnaire developed for the rapid assessment of pain. The BPI-sf modified provides information on the intensity of pain (the sensory dimension) as well as the degree to which pain interferes with function (the reactive dimension). The questionnaire asks questions about pain relief, pain quality, and the participant's perception of the cause of pain. The BPI-sf modified uses a numeric rating scale from 0 (No pain) to 10 (Pain as bad as you can imagine). Since pain can be quite variable over a day, the BPI-sf modified asked participants to rate their pain at the time of responding to the questionnaire (right now), and also at its worst, least and average over the last 24 hours. | Baseline, Week 12 | 
| Mean Change From Baseline to Week 12 in Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-F) Score | The FACIT-F Scale is a brief 13-item, symptom-specific questionnaire that specifically assesses the participant self-reported severity of fatigue and its impact upon daily activities and functioning. The FACIT-F uses a numeric rating scale of 0 (Not at all) to 4 (Very much) for each item to assess fatigue and its impact in the past 7 days. Total scores range from 0 to 52, with higher scores indicating less fatigue. | Baseline, Week 12 | 
| Population Pharmacokinetics (PK): Maximum Concentration at Steady State of Dosing (Cmax,ss) of LY3009104 |  | Baseline through 24 weeks | 
| Population PK: Area Under the Concentration Curve Versus Time at a Dosing Interval at Steady State (AUCtau,ss) of LY3009104 |  | Baseline through 24 weeks | 
| Mean Change From Baseline Through Week 12 in the ENSEMBLE Minimum Data Set 1.0 |  | Baseline, 12 weeks |
