Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Subjects will receive a total of 8 doses of placebo over a 12-week treatment period.
GSK3196165	GSK3196165	Subjects will receive a total of 8 doses of GSK3196165 over a 12-week treatment period.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in 24-hour Average Hand Pain Intensity, Averaged Over the 7 Days Prior to Week 6	Baseline (Day 1 Pre-dose) and Week 6	Participants were required to complete a daily pain NRS based on their 24-hour average hand pain intensity with the anchors "0" (no pain) and "10" (worst imaginable pain), which was averaged over the 7 days prior to assessment visit. The 7 day average score was calculated as sum of daily 24 hours average hand pain NRS scores in the 7 days prior to assessment visit, divided by number of entries recorded in those 7 days. Baseline visit was at Day 1 and Baseline value was defined as the average of the 7 days prior to baseline visit (Day 1 pre-dose). Change from Baseline is equal to post-dose visit value minus Baseline value. Intent-To-Treat Population comprised of all randomized participants who received at least one dose of study treatment (GSK3196165 or placebo).

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in 24 Hours Average Hand Pain Intensity Averaged Over the 7 Days Prior to Each Visit	Baseline (Pre-dose Day 1), Weeks 1, 2, 3, 4, 6, 8, 10 and 12	Participants were required to complete a daily pain NRS based on their 24-hour average hand pain intensity with the anchors "0" (no pain) and "10" (worst imaginable pain), which was averaged over the 7 days prior to assessment visit. The 7 day average score is calculated by sum of daily 24 hours average hand pain NRS scores in the 7 days prior to assessment visit, divided by number of entries recorded in those 7 days. Baseline visit was at Day 1 and Baseline value was defined as the average of the 7 days prior to baseline visit (Day 1 pre-dose). Change from Baseline is equal to post-dose visit value minus Baseline value.
Change From Baseline of Worst Hand Pain Intensity Over 24 Hours Averaged Over the 7 Days Prior to Each Visit	Baseline (Pre-dose Day 1), Weeks 1, 2, 3, 4, 6, 8, 10 and 12	Participants were required to complete a daily pain NRS based on their 24-hour worst hand pain intensity with the anchors "0" (no pain) and "10" (worst imaginable pain), which was averaged over the 7 days prior to assessment visit. The score is calculated as sum of daily 24 hours worst hand pain NRS scores in the 7 days prior to assessment visit, divided by number of entries recorded in those 7 days. Baseline visit was at Day 1 and Baseline value was defined as the average of the 7 days prior to baseline visit (Day 1 pre-dose). Change from Baseline is equal to post-dose visit value minus Baseline value.
Percentage of Participants Achieving a 30 Percentage Reduction From Baseline in 24 Hours Average Hand Pain Intensity at Each Visit	Baseline (Pre-dose, Day 1), Weeks 1, 2, 3, 4, 6, 8, 10, 12 and follow up (Week 22)	Participants were required to complete average pain NRS daily and rate the average hand pain over last 24 hours on a scale of 0 (no pain) to 10 (worst imaginable pain). The percentage of participants who achieved at least 30 percentage reduction from Baseline in the 24-hours average hand pain intensity as measured by daily NRS and averaged over 7 days prior to each visit is reported.

The percentage of participants who achieved at least 50 percentage reduction from Baseline in the 24-hours average hand pain intensity as measured by daily NRS and averaged over 7 days prior to each visit is presented.
Change From Baseline in Number of Tender Hand Joints at Each Visit	Baseline, Weeks 1, 2, 4, 6, 8, 10, and 12	Tender Hand Joint Count was measured by the total number of tender joints out of a possible 30 joints: 8 distal interphalangeal, 8 proximal interphalangeal, 2 interphalangeal joints, 10 metacarpophalangeal joints, 2 carpometacarpal joints across both hands. A joint was considered tender if it was scored \>0 on the tender joint severity scale. Joints were rated 0=no pain/tenderness, 1=mild pain, 2=moderate pain and 3=severe pain. Baseline is defined as Day 1 pre-dose value. Change from Baseline is equal to post-dose visit value minus Baseline value.
Change From Baseline in Physician Global Assessment (PhGA) of Disease Activity	Baseline (Day 1 Pre-dose), Weeks 2, 4, 8, and 12	Physicians were required to complete the global assessment of disease activity using single PhGA item with a NRS ranging from 0 (none) to 10 (extremely active). Baseline was defined as Day 1 pre-dose value. Change from Baseline is equal to post-dose visit value minus Baseline value.
Percentage of Participants Achieving a 30 Percentage Reduction From Baseline in 24 Hours Worst Hand Pain Intensity at Each Visit	Baseline (Pre-dose, Day 1), Weeks 1, 2, 3, 4, 6, 8, 10, 12 and follow up (Week 22)	Participants were required to complete worst pain NRS daily and rate the hand pain at its worst over last 24 hours on a scale of 0 (no pain) to 10 (worst imaginable pain).

The percentage of participants achieving at least 50 percentage reduction from Baseline in the 24-hours worst hand pain intensity as measured by daily NRS and averaged over 7 days prior to each visit is presented.
Change From Baseline in Australian Canadian Hand Osteoarthritis Index (AUSCAN) 3.1 NRS Scores at Each Visit.	Baseline (Day 1 Pre-dose), Weeks 1, 2, 4, 6, 8, 10, and 12	The AUSCAN Index is a self-administered questionnaire consisting of a 15-item scale which measures pain (5 items), stiffness (1 item) and degree of disability/physical function (9 items) during the preceding 48 hours. All items are rated on NRS scale with anchors "0" (none) to "10" (extreme). The scores for the pain and physical function components were calculated as simple summation of the item scores relating to that domain, so the Pain component ranges from 0 (i.e. all pain item scores are scored 0 \[none\]) to 50 (i.e. all pain item scores are scored 10 \[extreme\]), and the Physical Function component ranges from 0 (i.e. all physical function item scores are scored 0 \[none\]) to 90 (i.e. all physical function item scores are scored 10 \[extreme\]). The total AUSCAN score was calculated as simple summation of the 15 item scores and therefore ranges from 0 to 150. Baseline is defined as Day 1 pre-dose value. Change from Baseline is equal to post-dose visit value minus Baseline value.
Change From Baseline in Number of Soft Tissue Swollen Hand Joints at Each Visit	Baseline (Day 1 Pre-dose), Weeks 1, 2, 4, 6, 8, 10, and 12	Swollen Hand Joint Count was measured by the total number of soft tissue swollen hand joints out of a possible 30 joints: 8 distal interphalangeal, 8 proximal interphalangeal, 2 interphalangeal joints, 10 metacarpophalangeal joints, 2 carpometacarpal joint across both hands. In case of missing observations for soft tissue swollen hand joints then the remaining observations were assessed and weighted by dividing the number presented by the number of non-missing, and by multiplying by 30 for the joint count. Baseline is defined as Day 1 pre-dose value. Change from Baseline is equal to post-dose visit value minus Baseline value.
Change From Baseline in Patient Global Assessment (PtGA) of Disease Activity	Baseline, Weeks 2, 4, 8, and 12	Participants were required to complete the global assessment of disease activity using single PtGA item with an NRS ranging from 0 (very well) to 10 (very poor). Baseline was defined as Day 1 pre-dose value. Change from Baseline is equal to post-dose visit value minus Baseline value.
Number of Participants With Adverse Events (AE) and Serious Adverse Events (SAE)	Up to Week 22	An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment or events associated with liver injury and impaired liver function were categorized as SAE. All participants who received at least one dose of study treatment (GSK3196165 or placebo) were included in Safety Population.
Number of Participants With Infections	Up to Week 22	Adverse events of special interest (AESI) included serious infections like serious respiratory infections and tuberculosis and other opportunistic infections. Number of participants with infections has been reported.

Number of Participants With Anti-GSK3196165 Binding Antibodies	Up to Week 22	Serum samples were collected at indicated time points for anti-drug antibody (ADA) measurements. Anti-GSK3196165 binding antibody detection assay using tiered testing schema: screening, confirmation and titration steps was used for immunogenicity analysis. Samples taken after dosing with GSK3196165 that have a value at or above the cut-point were considered treatment-emergent ADA-positive. The number of participants with change from Baseline to any time post Baseline in the results of immunogenicity assessment as indicated by: negative to positive, positive to positive, positive to negative and negative to negative are presented.
Apparent Clearance After Subcutaneous Administration (CL/F) of GSK3196165	Day 3 and Pre-dose on Week 1, Week 4, Week 6, Week 12 and Week 22	Blood samples were collected at indicated time points and CL/F was estimated using population PK analysis.
