简要总结
This is an open, multicenter, extension study evaluating the safety and efficacy of CM310 for long-term treatment in patients with atopic dermatitis The primary objective is to assess the long-term safety of CM310 administered in patients with atopic dermatitis (AD).
详细描述
The secondary objective of the study is to assess the immunogenicity of CM310 in patients with AD, in the context of re-treatment, and to monitor efficacy parameters associated with long-term treatment.
