- •Subjects with hepatitis B [HbsAg is positive and detection of HBV-DNA indicates viral replication], hepatitis C [HCV antibody is positive and detection of HCV-RNA indicates viral replication], positive syphilis (except specific antibody detection positive, non-specific antibody detection negative and confirmed as inactive infection in combination with clinical judgment), known HIV positive history or HIV positive;
- •Subjects with moderate/severe liver injury caused by previous diseases, or AST or ALT or bilirubin ≥ 2 × ULN at screening;

- •Participation in any other interventional clinical trial (including drug and device clinical trials) within 1 month prior to screening;
- •Use of any systemic corticosteroids for more than 2 weeks within 3 months prior to screening or likely to require such therapy during the study (topical, inhaled, or nasal corticosteroids are allowed);
- •Use of GnRH agonists or GnRH antagonists (including participation in clinical trails of elagolix) within 6 months prior to screening; use of medroxyprogesterone acetate, danazol, aromatase inhibitors within 3 months prior to screening; use of oral contraceptives, or any hormonal treatment for endometriosis within 2 months prior to screening; use of Chinese herbal medicine for endometriosis treatment or symptom relief within 1 month prior to screening;
- •Subjects with IUD or subcutaneous contraceptive implants (the IUD or subcutaneous contraceptive implants removed more than 30 days prior to screening is allowed);
- •Subjects taking moderate or strong CYP450 3A inducers or OATP1B1 inhibitors within 1 month prior to the first dosing;
- •Pregnant or lactating women; or plan to have children during the trial (from signing the informed consent form to 3 months after using the study drug); or < 6 months after delivery; or < 3 months after abortion; or have a positive pregnancy test result during the screening period or on the day of randomization;
