Measure
Group A: CBP-201 300mg Q2W
The subjects receive a subcutaneous injection of CBP-201 600 mg on Day 1, begin to receive a subcutaneous injection of CBP-201 300 mg (2 ml) from Week 2 (W2), and receive treatment at the same dose every 2 weeks thereafter(Q2W) until W14.
Group B: Placebo Q2W
The subjects receive a subcutaneous injection of placebo 4 ml, begin to receive a subcutaneous injection of placebo 2 ml from W2, and receive placebo 2 ml every 2 weeks (Q2W) thereafter until W14.
Group C: Double-blinded CBP-201 300mg Q2W
Subjects who have achieved EASI-50 in the W16 pre-administration treatment assessment will be 1:1 randomized to one of the following two groups to receive study treatment starting from W16: The subjects receive a subcutaneous injection of CBP-201 300 mg every 2 weeks (Q2W) until W50.
Group D: Double-blinded CBP-201 300mg Q4W
Subjects who have achieved EASI-50 in the W16 pre-administration treatment assessment will be 1:1 randomized to one of the following two groups to receive study treatment starting from W16: The subjects receive a subcutaneous injection of CBP-201 300 mg every 4 weeks. In order to maintain the injection every 2 weeks blind, when not receiving CBP-201, the subjects receive an injection of placebo 2 ml once every 4 weeks until W50.
Group E: Open-Label CBP-201 300mg Q2W
Subjects who have not achieved EASI-50 in the W16 pre-administration treatment assessment will receive the following treatment starting from W16: The subjects receive a subcutaneous injection of CBP-201 300 mg every 2 weeks until W50.
