  Purpose

A multi-centre, randomised, dose ranging study to evaluate the safety and clinical efficacy of GSK2586184 in patients with chronic plaque psoriasis.

There will be 2 study cohorts (Cohorts A and B). Cohort A is the main study cohort, and this part of the study will be randomised, double-blind and placebo-controlled. Fifty-six subjects will be randomised in Cohort A: 14 subjects in each treatment group: 100 mg, 200 mg or 400 mg GSK2586184, or placebo. Cohort B is an exploratory, open-label investigation of the effect of 400 mg GSK2586184 on inflammatory gene expression in the skin and whole blood, and GSK2586184 concentrations in the skin. A maximum of 8 subjects will be included, and all subjects will take 400 mg GSK2586184.

In both Cohorts A and B, study medication will be administered orally (as tablets), twice daily, for up to 12 weeks.

Each subject will have 7 out-patient visits: Screening; Baseline & Start of treatment; Week 2; Week 4; Week 8; Week 12; and Follow-up (Week 16)

Primary Outcome Measures:
  • Percentage of Participants Who Had Achieved >=75% Improvement From Baseline in the Psoriasis Area Severity Index (PASI) Score at Week 12 (PASI 75) [ Time Frame: Baseline and Week 12 ]
    PASI score was determined by evaluation of body surface area (BSA) covered by plaque psoriasis in 4 areas (head/neck, arms, trunk and legs with area score of 0.1, 0.2, 0.3 and 0.4 respectively). This test included combination of both degree of involvement (assessed as per the % of affected body area using a 7-point scale such that 0=0% involvement, 1=1-9%, 2=10-29%, 3=30-49%, 4=50-69%, 5=70-89% and 6=90-100%) and severity (evaluated individually using a 5-point scale that ranged as 0=No evidence of sign, 1=slight evidence, 2=moderate evidence, 3=marked evidence and 4=very marked, most severe evidence of sign) of erythema, induration and desquamation in each of the same 4 areas. PASI score ranges from 0(no psoriasis) to 72(worse psoriasis). Final PASI=(sum of severity score for each area)x(% body affected score x area score). Baseline=Day 1. Percentage of participants who achieved >= 75% improvement from Baseline was reported with last observation carried forward (LOCF) analysis.

  • Percentage of Participants Who Had Achieved >=75% Improvement From Baseline in the Psoriasis Area Severity Index (PASI) Score at Week 12 (PASI 75) [ Time Frame: Baseline and Week 12 ]
    PASI score was determined by evaluation of BSA covered by plaque psoriasis in 4 areas (head/neck, arms, trunk and legs with area score of 0.1, 0.2, 0.3 and 0.4 respectively). This test included combination of both degree of involvement (assessed as per the % of affected body area using a 7-point scale such that 0=0% involvement, 1=1-9%, 2=10-29%, 3=30-49%, 4=50-69%, 5=70-89% and 6=90-100%) and severity (evaluated individually using a 5-point scale that ranged as 0=No evidence of sign, 1=slight evidence, 2=moderate evidence, 3=marked evidence and 4=very marked, most severe evidence of sign) of erythema, induration and desquamation in each of the same 4 areas. PASI score ranges from 0(no psoriasis) to 72(worse psoriasis). Final PASI=(sum of severity score for each area)x(% body affected score x area score). Baseline=Day 1. Percentage of participants who achieved >= 75% improvement from Baseline was reported with LOCF analysis.


Secondary Outcome Measures:
  • Number of Participants With Any Adverse Event (AE) or Serious Adverse Event (SAE) [ Time Frame: From Baseline (Day 1) until the Follow-up visit (Day 112) ]
    An AE is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. A SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability or incapacity, is a congenital anomaly or birth defect. Any SAEs assessed as related to study participation (e.g. study treatment, protocol-mandated procedures, invasive tests, or change in existing therapy) or related to a GSK product was recorded from the time a participant consents to participate in the study up to and including any follow-up contact.

  • Number of Participants With the Indicated Hematology Parameters Falling Outside of the Reference Range at Any Time Post-Baseline (BL) During Study [ Time Frame: From BL (Day 1) until the Follow-up visit (Day 112) ]
    Hematology parameters included: basophils, eosinophils, erythrocyte mean corpuscular hemoglobin (EMCHb) EMCHb concentration (EMCHbC), erythrocyte mean corpuscular volume (EMCV), erythrocyte sedimentation rate (ESR), erythrocytes, hematocrit (fraction 1), hemoglobin, leukocytes, lymphocytes, monocytes, neutrophils, segmented neutrophils, platelets, reticulocytes. BL values were obtained at Day 1. The number of participants with the indicated hematology parameters data outside of the reference range (with high and low) any time post-BL are presented. Anytime post-BL assessments included any scheduled and unscheduled post-BL assessment.

  • Number of Participants With the Indicated Clinical Chemistry Parameters Falling Outside the Reference Range at Any Time Post-Baseline (BL) During the Study [ Time Frame: From Baseline (Day 1) until the Follow-up visit (Day 112) ]
    Safety and tolerability were assessed by measuring the clinical chemistry parameters such as creatinine and cystatin C. BL values were obtained at Day 1. The number of participants with the indicated hematology parameter data outside of the reference range (> high or < low) at any time post-BL, including unscheduled or scheduled assessments, are presented.

  • Number of Participants With the Systolic (S) and Diastolic (D) Blood Pressure (BP) Falling Outside the Clinical Concern Range at Any Time Post-baseline During the Study [ Time Frame: From Baseline (Day 1) until the follow-up visit (Day 112) ]
    Vital sign monitoring included systolic and diastolic BP measurements. BP measurements were taken in the supine position after 5 minutes of rest. The number of participants with the SBP or DBP outside the clinical concern range at any time post-BL are presented. SBP "low" was measured as less than 85 millimeters of mercury (mmHg)and "high" was measured as greater than 160 mmHg. DBP "low" was measured as less than 45 mmHg and "high" was measured as greater than 100 mmHg. The BL values were those values obtained at Day 1. Anytime post-BL assessments included any scheduled and unscheduled post-BL assessment.

  • Number of Participants With the Heart Rate Falling Outside the Clinical Concern Range at Any Time Post-Baseline (BL) During the Study [ Time Frame: From Baseline (Day 1) until the Follow-up visit (Day 112) ]
    Vital sign monitoring included heart rate (HR) measurements. HR measurements were taken in supine position after 5 minutes of rest. The number of participants with HR outside the clinical concern range at any time post-BL are presented. HR "low" was any HR less than 40 beats per minute (bpm) and "high" was any HR greater than 110 bpm. The BL values were those values obtained at Day 1. Anytime post-BL assessments included any scheduled and unscheduled post-BL assessment.

  • Change From Baseline in Body Temperature [ Time Frame: From Baseline (Day 1) until Week 16 ]
    Vital sign monitoring included body temperature measurements. Body temperature measurements were taken in the supine position after 5 minutes of rest. Baseline is defined as the last result on or before the day of first dose. Change from Baseline was determined by subtracting the indicated time point value minus the Baseline value.

  • Number of Participants With the Indicated Maximum Change From Baseline in the Electrocardiogram (ECG) Findings [ Time Frame: From Baseline (Day 1) until the Follow-up visit (Day 112) ]

  • Change From Baseline in the Itch Visual Analogue Scale (VAS) Score at Week 2, 4, 8 and 12 [ Time Frame: From Baseline (Day 1) until Week 12 ]
    The visual analogue scale (VAS) was used to assess itch. The participants rated the intensity of itch over the past week by marking a line on a 100 millimeter(mm) (0 to 100 mm) long scale. A line placed on the extreme left, that is 0 mm indicated no noticeable itching sensation and extreme right that is 100 mm indicated maximum itching sensation. This scale has no subscales. The participant perception of their symptoms was measured using the VAS itch score. The Baseline value was the value obtained on Day 1. The change from Baseline was the difference between post-Baseline and Baseline.

  • Itch VAS Scores at Week 2, 4, 8 and 12 [ Time Frame: Week 2, 4, 8 and 12 ]
    The visual analogue scale (VAS) was used to assess itch. The participants rated the intensity of itch over the past week by marking a line on a 100 mm (0 to 100 mm) long scale. A line placed on the extreme left, that is 0 mm indicated no noticeable itching sensation and extreme right that is 100 mm indicated maximum itching sensation. This scale has no subscales. The participant perception of their symptoms was measured using the VAS itch score. Itch VAS scores at Week 2, 4, 8 and 12 are reported.

  • Change From Baseline of Dermatology Life Quality Index (DLQI) Score at Week 12 [ Time Frame: Baseline and Week 12 ]
    The DLQI was used to assess a participant's health-related quality of life.
