Efficacy of HS-10502: ORR Timeframe: From the date of first dose until the date of disease progression or withdrawal from study, approximately 2 years ORR is defined as the proportion of participants with BOR of confirmed CR or confirmed PR per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and PCWG3 (for prostate cancer only). 10. Efficacy of HS-10502: disease control rate (DCR) Timeframe: From the date of first dose until the date of disease progression or withdrawal from study, approximately 2 years The disease control was defined as the percentage of patients who have a best overall response (confirmed CR, PR, or stable disease for at least 5 weeks) per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and PCWG3 (for prostate cancer only). 11. Efficacy of HS-10502: duration of response (DoR) Timeframe: From the date of CR, PR until the date of disease progression or withdrawal from study, approximately 2 years DoR only applies to participants whose best overall response is CR or PR based on assessment per RECIST v1.1 (applicable for all solid tumors except prostate cancer) or per RECIST v1.1 and PCWG3 (for prostate cancer only). The start date is the date of first documented response of CR or PR (i.e. the start date of observed response, not the date when response was confirmed), and the end date is defined as the date of the first documented progression or death due to underlying cancer. 12. Efficacy of HS-10502: progression free survival (PFS) (applicable for all solid tumors except prostate cancer) Timeframe: From the date of randomization or first dose (if randomization is not needed) until the date of disease progression or withdrawal from study, approximately 2 years. PFS is defined as the time from the date of randomization or first dose (if randomization is not needed) to the date of the first documented progression or death due to any cause. PFS will be assessed per RECIST v1.1. 13. Efficacy of HS-10502: radiographic progression free survival (rPFS) (for prostate cancer only) Timeframe: From the date of randomization or first dose (if randomization is not needed) until the date of disease progression or withdrawal from study, approximately 2 years. rPFS is defined as the time from the date of randomization or first dose (if randomization is not needed) to the date of the first documented progression or death due to any cause. rPFS will be assessed per RECIST v1.1 (soft tissue) and PCWG3 (bone). 14. Efficacy of HS-10502: ORR evaluated by RECIST v1.1 and GCIG CA-125 (for ovarian cancer only) Timeframe: From the date of first dose until the date of disease progression or withdrawal from study, approximately 2 years For ovarian cancer, ORR is defined as the proportion of participants with BOR of confirmed CR or confirmed PR per both RECIST v1.1 and GCIG CA-125 criteria. 15. Efficacy of HS-10502: overall survival (OS) Timeframe: From the date of randomization or first dose (if randomization is not needed) until the documentation of death from any cause, approximately 4 years OS is defined as the time from the date of randomization or first dose (if randomization is not needed) to the date of death due to any cause. For each participant who is not known to have died as of the cutoff date for overall survival analysis, OS time was censored on the last date the participant is known to be alive. 16.
