This is a randomised, double-blind, multicentre clinical study to evaluate the efficacy, safety, tolerability, PK, and immunogenicity of SB17 compared to Stelara in subjects with moderate to severe plaque psoriasis.


Subjects will be randomised in a 1:1 ratio to receive either SB17 or Stelara via subcutaneous injection. At Week 28, subjects receiving Stelara will be randomised again in a 1:1 ratio to either continue on Stelara or be transitioned to SB17. Investigational products (IPs) (SB17 or Stelara) will be administered at Week 0, 4, and then every 12 weeks up to Week 40, and the last assessment will be done at Week 52.
