E.2 Objective of the trial |

Compare the efficacy of bimekizumab administered for 16 weeks versus adalimumab in the treatment of subjects with moderate to severe chronic plaque psoriasis (PSO).
|
|
E.2.2 | Secondary objectives of the trial |
- Evaluate the efficacy of bimekizumab compared to adalimumab after 4, 16, and 24 weeks of treatment
- Evaluate the efficacy of bimekizumab compared to adalimumab at achieving complete clearance (PASI100) after 16 weeks and 24 weeks of treatment
- Assess the maintenance of efficacy of bimekizumab dosing 1 versus dosing 2 at Week 56
- Assess Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), and TEAEs leading to withdrawal adjusted by duration of subject exposure to study treatment
|

depression
