Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Bimekizumab
Treatment: Drugs - Secukinumab
Other interventions - Placebo

Experimental: Bimekizumab dosage regimen 1 - Subjects randomized to this arm will receive bimekizumab dosage regimen 1 (BKZ 1).
At Week 16 subjects will be re-randomized and continue to receive BKZ 1 or to switch to bimekizumab regimen 2 (BKZ 2).
Placebo will be administered at pre-specified time-points to maintain the blinding over the double-blind Treatment Period.
Subjects allowed to enroll in the open-label extension (OLE) Period will receive BKZ 1 or BKZ 2. Subjects will switch from BKZ 1 to BKZ 2 at Week 64 or at the next scheduled Visit.
Eligible subjects who completed OLE, have entered Safety Follow Up (SFU) or completed SFU would start OLE2 on BKZ 1 before switching to BKZ 2 after 16 weeks or start OLE2 on BKZ 2.

Experimental: Bimekizumab dosage regimen 2 - Subjects randomized to this arm will receive bimekizumab dosage regimen 2 (BKZ 2) starting at Week 16 after initial treatment on bimekizumab regimen 1 (BKZ 1) for 16 weeks.
Placebo will be administered at pre-specified time-points to maintain the blinding over the double-blind Treatment Period.
Subjects allowed to enroll in the open-label extension (OLE) Period will receive BKZ 1 or BKZ 2. Subjects will switch from BKZ 1 to BKZ 2 at Week 64 or at the next scheduled Visit.
Eligible subjects who completed OLE, have entered SFU or completed SFU would start OLE2 on BKZ 1 before switching to BKZ 2 after 16 weeks or start OLE2 on BKZ 2.

Active Comparator: Secukinumab - Subjects will receive secukinumab. Subjects allowed to enroll in the open-label extension (OLE) Period will be re-randomized to receive bimekizumab dosage regimen 1 (BKZ 1) or bimekizumab dosage regimen 2 (BKZ 2).
Eligible subjects who completed OLE, have entered SFU or completed SFU would start OLE2 on BKZ 1 before switching to BKZ 2 after 16 weeks or start OLE2 on BKZ 2.


Treatment: Drugs: Bimekizumab
Subjects will receive bimekizumab at pre-specified time-points.

Treatment: Drugs: Secukinumab
Subjects will receive secukinumab at pre-specified time-points.

Other interventions: Placebo
Subjects will receive placebo at pre-specified time-points to maintain the blinding in the double-blind Treatment Period.
