  • Blood eosinophil≥ 200 cells per microliter within 6 months before screening;
  • During the screening, 40% of the predicted normal value \< pre-bronchodilator FEV1 \< 80% of the predicted normal value, within 12 months before randomization, reversible airflow restriction was recorded;
  • Asthma was inadequately controlled;
  • For women with childbearing potential, they are not pregnant or lactating, and the subjects and their partners voluntarily take effective contraceptive measures judged by the investigators during the treatment and at least 3 months after last dose.
