简要总结
The primary objective of the study is to evaluate the efficacy and safety of goflikicept (GFC) and olokizumab (OKZ) in patients with Still's disease
详细描述
This is an international, multicenter, double-blind, randomized, placebo-controlled, Phase III clinical trial to evaluate the efficacy and safety of goflikicept (GFC) administered over 16-36 weeks
Additionally, the study evaluates the pharmacokinetics/pharmacodynamics (PK/PD), immunogenicity, efficacy, and safety of GFC and olokizumab (OKZ) as the second-line therapy
The study includes the following periods:
- Screening period: up to 4 weeks
- Treatment Period
Eligible patients should be randomized to one of two treatment arms (in a 1:1 ratio):
- Active Treatment Arm taking GFC
- Placebo arm

盲法说明
Based on the Day 7 disease activity assessment, a decision is made to either continue masked therapy or to unmask and switch to second-line therapy. At the Day 7 assessment, responders remain masked.
In the event of non-response at the Day 7 assessment, non-responders are unmasked
