Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

bimekizumab

Study participants randomized to this arm receive bimekizumab dosage regimen 1 at pre-specified timepoints during the Initial Treatment Period (16 weeks). They continue to receive bimekizumab dosage regimen 2 in the Maintenance Period (32 weeks). Under certain conditions study participants may be offered to continue on bimekizumab dosage regimen 2 in the Open-label Extension (OLE) Period (104 weeks).

Group Type EXPERIMENTAL

bimekizumab

Intervention Type DRUG

Study participants receive bimekizumab (BKZ) administered as subcutaneous injection at pre-specified timepoints and dosage regimen during the study.

placebo

Intervention Type DRUG

Study participants receive placebo at pre-specified timepoints during the study to maintain the blinding.

ustekinumab

Study participants randomized to this arm receive ustekinumab at pre-specified timepoints during the Initial Treatment Period (16 weeks) and during the Maintenance Period. Under certain conditions participants may switch to bimekizumab dosage regimen 1 (16 weeks) and continue with bimekizumab dosage regimen 2 in the last 16 weeks of the Maintenance Period. Under certain conditions study participants may be offered to participate in the OLE Period also receiving bimekizumab dosage regimen 2.
