You may be eligible if
Age\>=18 years and \<=75 years of age at the time of consent.
Diagnosis of, and currently active psoriatic arthritis with \>=3 tender and \>=3 swollen joints, one of which must be either a knee or ankle joint suitable for synovial biopsies.
C-reactive protein (CRP) \>=3mg/l at the time of screening, thought by the investigator to be due to active PsA.
A negative test result for Rheumatoid Factor at screening.
Active PsA despite an adequate course of treatment with at least one of the following Disease-modifying anti-rheumatic drugs (DMARDS): methotrexate, sulfasalazine or leflunomide for a minimum of 3 months, with a stable dose prior to screening. The subject may have received prior treatment for their PsA with up to three oral DMARDS.
At least 2 active psoriatic skin lesions \>=3centimetre (cm) x 3cm diameter at the time of the screening visit which in the opinion of the investigator will still be present in the Pre- Treatment Phase. Each plaque should have a total PLSS of \>=5, including an induration score of \>=2 (moderate or above) and a score of \>=1 in erythema and scaling. The PLSS is the sum of the erythema, scaling and induration scores. The skin lesions should be located in areas usually shielded from natural light by clothing (e.g. trunk or proximal extremities) and should not include scalp, inguinal or genital lesions.
BMI within the range 18 - 35 kilogram per squared meter (kg/m\^2) (inclusive).
Female subjects are eligible to participate if they are not pregnant (as confirmed by a negative urine human chorionic gonadotrophin \[hCG\] test), not lactating, and at least one of the following conditions applies: 1. Pre-menopausal females with one of the following: a. Documented tubal ligation; b. Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion; c.

2\. Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone \[FSH\] and estradiol levels consistent with menopause \[refer to laboratory reference ranges for confirmatory levels\]). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.
Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until 12 weeks after the last dose of study medication:Vasectomy with documentation of azoospermia; Male condom plus female partner use of one of the GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Childbearing potential listed below. GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penilevaginal intercourse on a long term and persistent basis. a. Contraceptive subdermal implant effectiveness criteria including a \<1% rate of failure per year, as stated in the product label. b. Intrauterine device or intrauterine system that meets effectiveness criteria including a \<1% rate of failure per year, as stated in the product label c.

A subject will not be eligible for inclusion in this study if any of the following criteria apply:
Planned surgical joint procedure, including intra-articular, tendon sheath, or bursal corticosteroid injections, during the study.
Intra-articular corticosteroid injection, arthrocentesis or synovial biopsy on the joint that has been identified for biopsy or Magnetic resonance imaging (MRI) within 6 weeks of the Pre-Treatment biopsy and MRI.
Has undergone surgery, including synovectomy or arthroplasty, on the joint chosen for biopsy or MRI.
History of joint disease, other than PsA, at the knee or ankle joint chosen for biopsy and/or MRI (eg gout, pseudogout, osteoarthritis).
Diagnosed with a major chronic inflammatory or connective tissue disease other than Ps and PsA (e.g. rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, ankylosing spondylitis).
An active infection, or a history of infections as follows: a. A serious infection, defined as requiring hospitalization or intravenous antiinfectives within 8 weeks prior to Day 1. b. Oral anti-microbials within 14 days of Day 1. c. A history of opportunistic infections within 1 year of screening (e.g. pneumocystis jirovecii, cytomegalovirus pnemonitis, aspergillosis). This does not include infections that may occur in immunocompetent individuals, such as fungal nail infections or vaginal candidiasis, unless it is of an unusual severity or recurrent nature d.Recurrent or chronic infection or other active infection that, in the opinion of the investigator might cause this study to be detrimental to the subject e. History of Tuberculosis (TB), irrespective of treatment status f. A positive diagnostic TB test at screening defined as a positive QuantiFERON®-TBGold (Registered product of QFT-G; Cellestis Ltd., Carnegie, Australia) test or T-spot test. In cases where the QuantiFERON or T-spot test is indeterminate, the subject may have the test repeated once, but they will not be eligible for the study unless the second test is negative, or they have a negative Tuberculin Purified Protein Derivative (PPD) skin test. A positive PPD (Mantoux) test is defined as \>=5mm of induration (size of raised lump not redness).
