Overview
Brief Summary
Study to evaluate pharmacokinetics, efficacy, safety and immunogenicity of multiple switches between Humira® and ABP 501 (new high concentration formulation) compared with continued use of Humira® in participants with moderate to severe plaque psoriasis. This multi-center study is composed of two periods: A lead-in period of treatment with Humira® followed by a randomized two parallel arm period.

- •Participant has no known history of latent or active tuberculosis
Exclusion Criteria
- •Participant has erythrodermic psoriasis, pustular psoriasis, guttate psoriasis, medication induced psoriasis, or other skin conditions at the time of screening (eg, eczema) that would interfere with evaluations of the effect of investigational product of psoriasis
- •Participant has an active infection or history of infections
- •Participant has received biologic treatment for psoriasis within the previous month or 5 drug half-lives (whichever is longer) prior to enrollment
- •Participant has received nonbiologic systemic psoriasis therapy within 4 weeks prior to enrollment

Arms & Interventions
Continued-use Group (Adalimumab)
Randomized participants will receive continuous injection of adalimumab Q2W until last dose at Week 28.
Intervention: Adalimumab
Switching Group (Adalimumab - ABP 501)
Participants will initially receive adalimumab until Week 10 during the lead-in period. Thereafter, starting from Week 12, participants will switch between ABP 501 and adalimumab Q2W with last dose of ABP 501 at Week 28.
Intervention: Adalimumab
Switching Group (Adalimumab - ABP 501)
Participants will initially receive adalimumab until Week 10 during the lead-in period. Thereafter, starting from Week 12, participants will switch between ABP 501 and adalimumab Q2W with last dose of ABP 501 at Week 28.
Intervention: ABP 501
