Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a randomized, active-controlled, double-blind, phase 3 study to compare the efficacy and safety of CT-P43 to Stelara in patients with moderate to severe plaque psoriasis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

CT-P43, containing the active ingredient ustekinumab, is a human IgG1κ monoclonal antibody that is being developed as a biosimilar medicinal product to the reference product, Stelara. The purpose of this study is to demonstrate similar efficacy and safety of CT-P43 and Stelara in patients with moderate to severe plaque psoriasis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CT-P43

All patients who were initially randomized to the CT-P43 group on Day 1 (Week 0) will continue their treatment with CT-P43 until Week 40.

Group Type EXPERIMENTAL

CT-P43

Intervention Type BIOLOGICAL

45mg or 90mg dose subcutaneous administration

Stelara

Patients who were initially randomized to Stelara group on Day 1 (Week 0) will be randomized again in a ratio of 1:1 to either continue Stelara or undergo transition to CT-P43 prior to dosing at Week 16. Thereafter, patients will continue their treatment until Week 40.
