Healthy volunteers will be randomly assigned in a 1:1 ratio to receive either IBI3027 or DUPIXENT?. The dosage for both groups is 300 mg. The entire study includes a 28-day screening period and a 56-day observation period (including 3 days of hospitalization). Randomization is stratified by body weight at baseline (D1) ≤ 70 kg vs. \\> 70 kg.
