GB491+ Fulvestrant

Group Type EXPERIMENTAL

GB491+ Fulvestrant

Intervention Type DRUG

GB491: The dose of GB491 is 150 mg, BID, which should be taken with a meal. The drug is administered according to the patient's dose group until the progression of disease or an intolerable toxicity occur or meet the criteria for termination of treatment or the patient withdraw informed consent or the sponsor discontinues the trial.

Fulvestrant: Intramuscular injection of flurvexine 500mg on day 1 and day 15 of the first cycle, and flurvexine 500mg on day 1 of the second and subsequent cycles. Flurvexine 500mg should be given slowly (1-2 minutes per injection) on both sides of the buttocks, once 250 mg on each side. The drug is administered according to the patient's dose group until the progression of disease or an intolerable toxicity occur or meet the criteria for termination of treatment or the patient withdraw informed consent or the sponsor discontinues the trial.

Intervention Type DRUG

Placebo: The dose of Placebo is 150 mg, BID, which should be taken with a meal. The placebo is administered according to the patient's dose group until the progression of disease occur or meet the criteria for termination of treatment or the patient withdraw informed consent or the sponsor discontinues the trial.

Fulvestrant: Intramuscular injection of flurvexine 500mg on day 1 and day 15 of the first cycle, and flurvexine 500mg on day 1 of the second and subsequent cycles. Flurvexine 500mg should be given slowly (1-2 minutes per injection) on both sides of the buttocks, once 250 mg on each side. The drug is administered according to the patient's dose group until the progression of disease or an intolerable toxicity occur or meet the criteria for termination of treatment or the patient withdraw informed consent or the sponsor discontinues the trial.
