4. Current treatment or history of treatment for psoriasis with any investigational or approved IL-17, IL-12 or IL-23 antagonist biological agents (e.g. secukinumab, briakinumab, tildrakizumab, ustekinumab etc.) within 6 months prior to the first administration of study drug.
5. Current treatment or history of treatment for psoriasis with other investigational or approved biological agents (e.g. anti-TNFα inhibitors - adalimumab, etanercept, infliximab, alefacept etc.) within 3 months prior to the first administration of study drug
6. Current treatment or history of treatment for psoriasis with non-biological systemic medications or immunomodulators (including systemic steroids, apremilast, methotrexate, cyclosporine, acitretin, etc.) or phototherapy within 4 weeks prior to the first administration of study drug.
7. Treatment with medicated topical agents (having active pharmaceutical ingredient that can impact or interfere with the effect of the study drug) within 2 weeks prior to the first administration of study drug.
8. Evidence of organ dysfunction (e.g. liver dysfunction ≥ 1.5 X of ULN for ALT, AST or ALP or Total Bilirubin, or renal dysfunction of ≥ 1.5X of ULN of serum creatinine)
9. Any surgery requiring general anesthesia within 3 months prior to screening
10. History of malignancy within last 5 years except patients with non-melanoma skin cancer or carcinoma in situ of cervix who can participate in the study. Adequately treated cutaneous basal or squamous cell carcinoma are allowed.

Patients with a positive QFT or MT may participate in the study if further work up as per the opinion of the investigator (like Chest X-ray or CT scan of Chest or other locally acceptable method for diagnosing active tuberculosis) establishes that patient does not have active tuberculosis. Patients with latent tuberculosis should not be enrolled except when they are not planned to start prophylaxis for tuberculosis during the study period.

16. History of alcohol or substance abuse that will affect compliance to study procedures/schedule as per Investigator opinion

19. Male patients who are sexually active with WOCBP, not willing to use reliable contraception methods as mentioned in section 8.14
20. Lactating women or WOCBP who are neither surgically sterilized nor willing to use reliable contraceptive methods (hormonal contraceptive, IUD or any double combination of male or female condom, spermicidal gel, diaphragm, sponge, cervical cap). Please see section 8.14 for acceptable contraceptive practices

22. Has received another new chemical entity/non-biologic investigational drug within 28 days or 5 half-lives of investigational drug (whichever is longer) prior to study day 1
23. History of other auto-immune disorders (except psoriasis and psoriatic arthritis) where treatment with systemic immunosuppressants is required
24. History of active infection and/or febrile illness within 7 days prior to Day 1. The infection adequately treated by antibiotics during the screening period as per investigator opinion will be allowed to undergo randomization, provided patient is stable for at least 7 days before randomization
25. Current swab-positive or suspected (under investigation) Covid-19 infection or fever and other signs or symptoms suggestive of Covid-19 infection with recent contact of person(s) with confirmed Covid-19 infection, at screening or Day 1
26. History or presence of any major medical illness (e.g. renal, hepatic, hematologic, gastrointestinal, endocrine, pulmonary, immunologic, or local active infection/infectious illness) or psychiatric disease, or clinically significant laboratory / ECG abnormalities at screening, any or a combination of illnesses, which, in the opinion of the PI, may either put the patient at risk because of participation in the study, or influence the results or the patient's ability to participate in the study
