This is a study to demonstrate the clinical efficacy and safety of the nanobody® sonelokimab administered subcutaneously (sc) compared with placebo in the treatment of adult participants with active psoriatic arthritis. The study includes adalimumab treatment as an active reference arm.

Patients will be randomized to receive one of three sonelokimab treatment regimes, adalimumab or placebo. Primary efficacy evaluation will take place at Week 12. Patients will be allocated to a further 12 weeks of treatment with sonelokimab or adalimumab based on response assessment at week 12. In certain countries, treatment will end at week 12.
