What this phase means
Phase 1: the first tests in people. The main question is safety and dose, not whether it cures the condition. Groups are small. Side effects are watched closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are SKYRIZI, SKYRIZI, or CKD-704. The registry lists allocation as randomized. This is a Phase 1, first-in-human (FIH), randomly assigned, neither you nor the study doctors know who gets the real treatment, single-dose, parallel-group, 3-arm study to compare PK, safety, tolerability, and immunogenicity profiles of CKD-704, EU-approved Skyrizi, and US-licensed Skyrizi in healthy adult participants.
They plan to enroll about 213 people at Warsaw. Taking part typically means an infusion or injection of a biologic plus check-ins.
