Intervention

Drug:
• TQH2722 injection
TQH2722 is a fully human monoclonal antibody directed against the interleukin (IL)-4 receptor a subunit (IL-4Ra) of IL-4 heterodimeric type I and type II receptors that mediate IL-4/IL-13 signaling through this pathway. Blockade of these receptors broadly suppresses type 2 inflammation associated with atopic/allergic diseases.
• Placebo to match TQH2722
