 (submitted: March 28, 2019)
Change From Baseline in Psoriasis Area and Severity Index (PASI) Score at Week 12 [ Time Frame: Baseline (Day 1 pre-dose), Week 12 ]
The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percentage of body surface area (BSA) affected. In each area, the sum of the severity rating scores for erythema, induration and scaling is multiplied by the score representing the percentage of this area involved by psoriasis, multiplied by a weighting factor (head 0.1; upper limbs 0.2; trunk 0.3; lower limbs 0.4). The sum of the numbers obtained for each of the four body areas is the PASI. The PASI score can vary in increments of 0.1 units from 0.0 to 72.0, with higher scores representing increasing severity of psoriasis.

    A PASI75 response is a 75% or greater reduction from baseline in PASI score. The PASI score can vary in increments of 0.1 units from 0.0 to 72.0, with higher scores representing increasing severity of psoriasis.
  • Change From Baseline in PASI Scores at Week 4 by Induction Dose [ Time Frame: Baseline (Day 1 pre-dose), Week 4 ]
    Change from baseline in PASI scores at Week 4 was presented by induction dose (ie, PF-06700841 60 mg QD, 30 mg QD, and placebo). The PASI score can vary in increments of 0.1 units from 0.0 to 72.0, with higher scores representing increasing severity of psoriasis.
  • Percentage of Participants Achieving PASI75 Responses at Weeks 1, 2, 4, 6, 8, 10, 14, 16 [ Time Frame: Weeks 1, 2, 4, 6, 8, 10, 14, 16 ]
    A PASI75 response is a 75% or greater reduction from baseline in PASI score. The PASI score can vary in increments of 0.1 units from 0.0 to 72.0, with higher scores representing increasing severity of psoriasis.

    A PASI90 response is a 90% or greater reduction from baseline in PASI score. The PASI score can vary in increments of 0.1 units from 0.0 to 72.0, with higher scores representing increasing severity of psoriasis.
  • Change From Baseline in PASI Scores at Weeks 1, 2, 4, 6, 8, 10, 14, 16 [ Time Frame: Baseline (Day 1 pre-dose), Weeks 1, 2, 4, 6, 8, 10, 14, 16 ]

    The PASI score can vary in increments of 0.1 units from 0.0 to 72.0, with higher scores representing increasing severity of psoriasis.
  • Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: From first dose of study treatment (Day 1) up to Week 20 ]
    An AE (non-serious and serious) was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening (immediate risk of death); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect; or an important medical event. Any such events with initial onset or increasing in severity after the first dose of study treatment were counted as treatment-emergent.
  • Number of Participants Who Discontinued From the Study Due to Treatment-Emergent AEs [ Time Frame: From first dose of study treatment (Day 1) up to Week 20 ]
    The number of participants who discontinued from the study due to treatment-emergent AEs is presented. Note for data reported under this Outcome Measure: Per sponsor reporting standard, pregnancy was counted as AE for AE data tables while it was counted separately in the disposition data table (Participant Flow Module).
  • Change From Baseline in Blood Lipid Level at Weeks 4 and 12 [ Time Frame: Baseline (Day 1 pre-dose), Weeks 4 and 12 ]
    Lipid panel included low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, total cholesterol, and triglycerides.
