Experimental: sonelokimabEXPERIMENTALAll participants will receive sonelokimab 120 mg Q4W for up to 2 years
sonelokimabEXPERIMENTALSubjects will receive sonelokimab 120mg subcutaneously (SC) as an induction regimen of 4 doses, followed by sonelokimab SC every 4 weeks maintenance dose starting at Week 8
PlaceboPLACEBO_COMPARATORSubjects randomized to this arm will receive placebo Q2W from Weeks 0 to 6 then Q4W starting at Week 8 up to Week 16. They will receive sonelokimab 120 mg Q2W for 4 doses from Weeks 16 to 22 then Q4W from Week 24 up to Week 48
sonelokimab dose 1EXPERIMENTALSubjects randomized to this arm will receive assigned sonelokimab dosage regimen and placebo to maintain the blinding with adalimumab and placebo arms during the Treatment Period.
