Arm Intervention/treatment
Experimental: KHK4827 Drug: KHK4827
140 mg (dosage may be increased to 210 mg in case of insufficient efficacy)

Primary Outcome Measures :
  1. Clinical Global Impression (CGI) [ Time Frame: 52 weeks ]
    CGI is a 4-point scale that requires the investigators/subinvestigators to assess how much the subject's illness has improved or worsened relative to a baseline state. Scores on the scale are rated as: 1, remission; 2, improved; 3, no change; 4, worsened

Secondary Outcome Measures :
  1. Percent improvement from baseline in Psoriasis Area and Severity Index (PASI) [ Time Frame: 52 weeks ]
  2. American College of Rheumatology (ACR) 20 (only in subjects with psoriasis arthritis) [ Time Frame: 52 weeks ]
  3. Pustular symptom score (only in subjects with pustular psoriasis) [ Time Frame: 52 weeks ]
  4. Static physician's global assessment (sPGA) of "clear or almost clear (0 or 1)" at Week 12 (only in subjects with psoriatic erythroderma) [ Time Frame: 52 weeks ]
  5. sPGA of "clear (0)" at Week 12 (only in subjects with psoriatic erythroderma) [ Time Frame: 52 weeks ]
  6. Body surface area involvement (BSA) of lesion at Week 12 (only in subjects with psoriatic erythroderma) [ Time Frame: 52 weeks ]
  7. Incidence and types of adverse events and adverse reactions [ Time Frame: 52 weeks ]
  8. Laboratory values and vital signs [ Time Frame: 52 weeks ]
  9. Profiles of pharmacokinetics [ Time Frame: 52 weeks ]
    Concentration of KHK4827 in serum

  10. Development of anti-KHK4827 antibody [ Time Frame: 52 weeks ]
