A Study for Patients With Rheumatoid Arthritis on Methotrexate (MTX) With an Inadequate Response to TNFα Inhibitor Therapy

A Phase 2 Study of Multiple Intravenous Doses of LY2127399 in Patients With Rheumatoid Arthritis on Concomitant Methotrexate and an Inadequate Response to TNFα Inhibitor Therapy

The purpose of this study is to explore whether LY2127399 is effective in relieving signs and symptoms of rheumatoid arthritis (RA) in patients with a history of inadequate response or intolerance to at least 1 Tumor Necrosis Factor-Alpha (TNFα) inhibitor therapy. Examples of these TNFα inhibitor therapies that are currently on the market include Enbrel® (etanercept), Remicade® (infliximab), and Humira® (adalimumab).

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.	16 weeks
Percentage of Participants Achieving American College of Rheumatology (ACR)70 Response at Week 16	ACR70 Responder Index is a composite of clinical, laboratory, and functional measures in rheumatoid arthritis. An ACR70 Responder is defined as a participant with at least 70% 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.	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.	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.	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.	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.	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.	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.	Baseline, 16 weeks
Percent Change From Baseline in C-reactive Protein (CRP) at Week 16		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.	Baseline, 16 weeks
Number of Participants With Response (Response Rate) Based Upon European League Against Rheumatism Responder Index, 28 Joint Count (EULAR28) at Week 16	EULAR28 categorizes clinical response based upon improvement since baseline in Disease Activity Score modified to include the 28 joint count (DAS28) and post-baseline DAS28. 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). EULAR28 categories include: No Response (improvement in DAS28 of less than or equal to 0.6 units or post-baseline DAS28 score greater than 5.1 with improvement by less than or equal to 1.2 units), Moderate Response (post-baseline DAS28 score less than or equal to 5.1 with improvement by more than 0.6 units but no greater than 1.2 units or post-baseline DAS28 score greater than 3.2 with improvement by more than 1.2 units), and Good Response (post-baseline DAS28 score less than or equal to 3.2 with improvement by more than 1.2 units).	16 weeks

Pharmacodynamics: Change From Baseline in Total B Cells (CD20 + CD3-) as a Percentage of Total Lymphocytes	B-lymphocyte antigen CD20 or CD20 is an activated-glycosylated phosphoprotein expressed on the surface of all mature B-cells. For this outcome, total B cells (CD20+CD3- cells) are expressed as the relative percent of lymphocytes. There is no reference range provided for this parameter by the performing laboratory.	Baseline, 16 weeks
Pharmacodynamics: Change From Baseline in Serum Immunoglobulins at Week 16	Serum immunoglobulin measured by Immunoglobulin A (IgA), Immunoglobulin G (IgG), and Immunoglobulin M (IgM) levels.	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.	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.	Pre-dose, Day 1 through Week 24
