About this trial
The goal of this clinical trial is to learn the safety and PK of the single dose of BL0175 Injection in postmenopausal women and to compare that with a single dose of Fulvestrant Injection. The main questions it aims to answer are:
* What medical problems do participants have when using drug BL0175? * How long can BL0175 remain in your blood? Participants will receive a single dose of drug BL0175 or a single dose of Fulvestrant Injection in a randomized method
