Patients who meet any of the following criteria will not be eligible for the study: 1. Current diagnosis of non-plaque forms of psoriasis, e.g., erythrodermic, guttate, or pustular psoriasis; 2. Known allergies or hypersensitivities that can have potential impact on patient's participation as determined by the Investigator; 3. Receiving drugs that are known to exacerbate psoriasis such as beta blockers, calcium channel blockers, antimalarial drugs or lithium; 4.

History of infection requiring oral antimicrobial therapy within 2 weeks prior to first dose of IP; 8. Patients with active tuberculosis, prior history of unsuccessfully treated tuberculosis (TB), latent TB (patients who are positive for test for latent TB e.g. QuantiFERON®-TB Gold test or appropriate test), or those who are at risk of developing TB; 9. History of any lymphoproliferative disorder (such as Epstein Barr Virus [EBV] - related lymphoproliferative disorder), history of lymphoma, leukemia, or signs and symptoms suggestive of current lymphatic disease; 10. Patients suffering from significant acute or chronic, localized or disseminated infections (bacterial/fungal/viral) or sepsis, or patients with a history of recurring infections except Herpes simplex within 3 months prior to screening, or those who are at an increased risk of developing infections or sepsis as determined by the Investigator; 11. History or presence of any immunological disease or use of immunosuppressive or any therapy within a period that can have a 12. Recent live vaccine administration within 4 weeks prior to screening and during the study; 13.
