Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare the efficacy and safety of QL2302 and Tezspire® in patients with uncontrolled severe asthma. The main questions it aims to answer are:

* if the efficacy of QL2302 and Tezspire® are similar
* if the safety of QL2302 and Tezspire® are similar

Participants will be randomised to QL2302 or Tezspire® group and asked to receive one injection of QL2302 or Tezspire® subcutaneously every four weeks till Week 48, which means participants will receive a total of 13 injections. And be observed for another 12 weeks after the end of treatment.
