Primary Outcome Measures:
  • Change from baseline to the end of treatment in Psoriasis Area Severity Index (PASI) score [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Safety assessed from baseline to end of treatment by recording adverse events, physical examinations, vital signs, laboratory assessments and electrocardiograms (ECGs) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline to end of treatment in Physicians Static Global Assessment (PSGA) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Change from baseline to end of treatment in percent body surface area (BSA) [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
  • Success of the treatment of psoriasis as measured by a Physician's Static Global Assessment (PSGA) of Almost Clear or Clear [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
