Study Arms (2)
TQC2731 injection
EXPERIMENTALTQC2731 injection, 4 weeks as a treatment cycle. Study drug administration from Day 0 up to Week 48.
Placebo
PLACEBO COMPARATORPlacebo,4 weeks as a treatment cycle.Study drug administration from Day 0 up to Week 48.
Interventions
TQC2731 injection can specifically bind to the Thymic Stromal Lymphopoietin (TSLP) protein, blocking TSLP-dependent downstream signaling expression in engineered cells and inhibiting the production of inflammatory cytokines.
