Identify Effective Doses of LY01021 in Controlled Ovarian Hyperstimulation (COH) for Female Subjects Undergoing Assisted Reproductive Technology (ART)

This is a multicentre, open-label, dose-finding, phase 2 study that will recruit approximately 90 female subjects undergoing COH for in vitro fertilization (IVF) or intracytoplasmic single sperm injection (ICSI). Three LY01021 dose groups of 40 mg QD, 30 mg QD, and 20 mg QD will be included, with not exceed 45 subjects in each group to investigate the efficacy and safety.
