简要总结
Safety and Efficacy study of AVT04 (Alvotech Biosimilar to Ustekinumab), in patients with moderate to severe plaque psoriasis
详细描述
AVT04 is a fully human immunoglobulin class G1κ monoclonal antibody that specifically binds to the shared p40 protein subunit of IL-12 and IL-23 and therefore inhibits their activites
AVT04 is being developed to be a biosimilar with the European Union (EU)-licensed drug Stelara® (hereafter referred to as Stelara) ustekinumab, Anatomical Therapeutic Chemical code: L04AC05) injection for subcutaneous (SC) and intravenous use. Stelara is an anti-IL-12 and anti-IL-23 monoclonal antibody approved for various indications. Indications approved in the EU11 and United States (US)12 include: PsO in adult and pediatric patients, psoriatic arthritis, Crohn's disease, and ulcerative colitis. Indications approved in the People's Republic of China include PsO and Crohn's disease.13 Approval status may differ in other geographic regions.
This is a multicenter, double-blind, randomized, active control clinical study to compare the efficacy, safety, and immunogenicity of AVT04 versus Stelara in patients with moderate to severe chronic PsO.
The active period of Study AVT04-GL-301 comprises 2 stages:
- Stage 1: Primary Efficacy Assessment (Day 1 to Week 15)
- Stage 2: Long Term Efficacy and Safety Assessment (Week 16 to 52) Stage 1 On Day 1, after successfully completing Screening activities, eligible patients will be randomized into Groups 1 and 2, in a 1:2 ratio (AVT04:Stelara), and begin Stage 1.
