Primary Outcome Measures:
  • Psoriasis Area and Severity Index (PASI)75% [ Time Frame: 3 month ]
    Patient disease and skin condition will be assessed using Psoriasis Area and Severity Index and compared to condition on baseline, The PASI score will be calculated at each visit

Secondary Outcome Measures:
  • PASI 50 [ Time Frame: 3 month ]
    The PASI 50 is an assessment of the proportion of patients who achieve at least 50% improvement in the PASI score from baseline Psoriasis Area and Severity Index (PASI)will be calculated at each visit

  • Durability of Response [ Time Frame: 3 months ]
