- progression-free survival (PFS), double-blinded period [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years ]PFS is measured from the date of randomization until progression or death, whichever is first met
- pharmacokinetic profiles of Chidamide, open-label period [ Time Frame: 0,1,2,4,8,12,24,48,72 hours after the first dose of Chidamide on day 2 at induced stage (4 days in total); 0,1,2,4,8,12,24,48,72 hours post-dose on day 1 of cycle 1 at combination treatment stage ]The pharmacokinetic parameters include Area under the plasma concentration versus time curve (AUC) , Peak Plasma Concentration (Cmax), time to reach Cmax (Tmax), mean concentration at steady state (Css)
- pharmacokinetic profiles of exemestane, open-label period [ Time Frame: 0,1,2,4,8,12,24 hours after the first dose of exemestane on day 1 at induced stage (4 days in total); 0,1,2,4,8,12,24,48,72 hours post-dose on day 1 of cycle 1 at combination treatment stage ]The pharmacokinetic parameters include Area under the plasma concentration versus time curve (AUC) , Peak Plasma Concentration (Cmax), time to reach Cmax (Tmax), mean concentration at steady state (Css)
- acetylation level of histone H3, open-label period [ Time Frame: pre-dose of Chidamide on day 2 at induced stage (4 days in total); pre-dose of Chidamide on day 1 of cycle 2 at combination treatment stage ]The acetylation level of histone H3 is assayed by enzyme-linked immuno sorbent assay (ELISA).
- overall survival, double-blinded period [ Time Frame: Time from randomization to death from any cause, assessed up to 6 years ]OS is measured from the date of randomization until death
- duration of response (DOR), double-blinded period [ Time Frame: From the first date of response until the date of first documented progression, assessed up to 3years ]DOR is measured from the first date when criteria for response is met until the first date when the criteria for progression is met
- objective response rate (ORR), open-label period and double-blinded period [ Time Frame: Response is assessed once every 6 weeks, assessed up to 3 years ]ORR is defined as percentage of participants with Complete Response and Partial Response, assessed by the investigators according to the Response Evaluation Criteria in Solid Tumors (RECIST)
- clinical benefit rate (CBR), open-label period and double-blinded period [ Time Frame: Response is assessed once every 6 weeks, assessed up to 3 years ]ORR is defined as percentage of participants with Complete Response, Partial Response or Stable Disease ≥ 24 weeks, assessed by the investigators according to the Response Evaluation Criteria in Solid Tumors (RECIST)
- PFS, open-label period [ Time Frame: Time from the start of treatment to the earliest of documented disease progression, or death, assessed up to 3 years ]PFS is measured from the start of treatment until progression or death, whichever is first met
