ACR50 Responder Index is a composite of clinical, laboratory, and functional measures in rheumatoid arthritis. ACR50 Responder is defined as a participant with greater than 50% improvement from baseline in both tender and swollen joint counts and in at least 3 of the following 5 criteria: physician global assessment, patient global assessment, functional ability measure (Health Assessment Questionnaire-Disability Index which measures participants' perceived degree of difficulty when performing various daily activities), visual analog pain scale, and erythrocyte sedimentation rate or C-reactive protein.

Time frame: 16 weeks

Secondary Outcomes

Number of Participants Experiencing An Adverse Event

Serious adverse events and other non-serious adverse events are located in the Reported Adverse Event section.

Time frame: Baseline up to 68 weeks

Change From Baseline in Medical Outcome Study 36-Item Short Form Health Survey (SF-36) at Week 16

Self-reported questionnaire of 36 questions in 8 domains (physical functioning, social functioning, bodily pain, vitality, mental health, role-physical, role-emotional, general health). Each domain is scored by summing individual items and transforming scores into a 0-100 scale (higher scores=better health status/function). The mental and physical component summaries are based on the 8 domains. Component scores are transformed scores representing a mean (50) and standard deviation (10) in the general United States (US) population. Scores \> or \<50 are above or below the average US population.

Time frame: Baseline, 16 weeks

Percentage of Participants Achieving American College of Rheumatology (ACR) 20 Response at Week 16

ACR20 Responder Index is a composite of clinical, laboratory, and functional measures in rheumatoid arthritis. An ACR20 Responder is defined as a participant with at least 20% improvement from baseline in both tender and swollen joint counts and in at least 3 of the following 5 criteria: physician global assessment, patient global assessment, functional ability measure (Health Assessment Questionnaire-Disability Index which measures participants' perceived degree of difficulty when performing various daily activities), visual analog pain scale, and erythrocyte sedimentation rate or C-reactive protein.

Time frame: 16 weeks

Change From Baseline in Tender Joint Count at Week 16

The number of tender and painful joints is determined by examination of 28 joints (14 on each side) which include: the 2 shoulders, the 2 elbows, the 2 wrists, the 10 metacarpophalangeal joints, the 2 interphalangeal joints of the thumb, the 8 proximal interphalangeal joints, and the 2 knees. The joints are assessed and classified as tender or not tender.

Time frame: Baseline, 16 weeks

Change From Baseline in Swollen Joint Count at Week 16

The number of swollen joints is determined by examination of 28 joints (14 on each side) which include: the 2 shoulders, the 2 elbows, the 2 wrists, the 10 metacarpophalangeal joints, the 2 interphalangeal joints of the thumb, the 8 proximal interphalangeal joints, and the 2 knees. The joints are assessed and classified as swollen or not swollen.

Time frame: Baseline, 16 weeks

Change From Baseline in Participant's Assessment of Joint Pain at Week 16

Participant's assessment of joint pain using a visual analog scale (VAS), which ranged from 0 to 100 millimeters, where 0 indicated no pain and 100 indicated worst possible pain.

Time frame: Baseline, 16 weeks

Change From Baseline in Participant's Assessment of Disease Activity at Week 16

Participant's assessment of their current arthritis disease activity using a visual analog scale (VAS), which ranged from 0 to 100 millimeters, where 0 indicated no arthritis activity and 100 indicated extremely active arthritis.

Time frame: Baseline, 16 weeks

Change From Baseline in Physician's Global Assessment of Disease Activity at Week 16

Physician's global assessment of arthritis disease activity using a visual analog scale (VAS) which ranged from 0 to 100 millimeters, where 0 indicates no arthritis activity and 100 indicates extremely active arthritis.

Time frame: Baseline, 16 weeks

Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 16

The HAQ-DI questionnaire scores the participant's self-perception on the degree of difficulty when dressing and grooming, arising, eating, walking, hygiene, reach, grip, and performing other daily activities (0=without any difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do). The scores for each of the functional areas, which have a range from 0 to 3, are averaged to calculate the functional disability index. Higher scores are associated with greater disability.

Time frame: Baseline, 16 weeks

Percent Change From Baseline in C-reactive Protein (CRP) at Week 16

Time frame: Baseline, 16 weeks

Change From Baseline in Disease Activity Score (DAS28) at Week 16

Disease Activity Score (modified to include the 28 joint count \[DAS28\]) consists of a composite score of the following variables: tender joint count (TJC28), swollen joint count (SJC28), C-reactive protein (CRP), and participant global assessment of their disease activity (patient global VAS). It is calculated by using the following formula:DAS28-CRP=0.56 times the square root of(28TJC)+0.28 times the square root of(28SJC)+0.36\*natural log (ln)(CRP+1)+0.014\*patient global VAS+0.96. Scores ranged from 1.0-9.4, where lower scores indicated less disease activity, and remission was DAS28-CRP \<2.6. A decrease in DAS28-CRP indicated an improvement in participant's condition.

Time frame: Baseline, 16 weeks

Pharmacokinetics: Predicted Population Mean Parameter: C-trough Steady-state

C-trough is defined as the concentration of LY at the end of the dosing interval at steady state. Mean C-trough value was obtained by conducting a simulation consisting of 1000 participants. The simulated data were then used to determine the noncompartmental PK parameters for each regimen. Mean and standard deviation of the Ctrough values were calculated for each dose group based on simulated data.

Time frame: Pre-dose, Day 1 through Week 24

Pharmacokinetics: Predicted Population Mean Parameter: T-half Life (t1/2, Tau)

T-half life (t1/2, tau) is defined as the apparent steady state elimination within the dosing interval. T-half life was obtained by conducting a simulation consisting of 1000 participants using the study drug regimens (30 and 80 mg, intravenous infusion over 30 minutes, once every 3 weeks). The simulated data were then used to determine the noncompartmental PK parameters for each regimen. Mean and standard deviation of the t-half life values were calculated for each dose group based on simulated data.

Time frame: Pre-dose, Day 1 through Week 24
