What was measured

Duration of Response (DOR) was defined as the duration between the date of first documented Best Overall Response (BOR) of Complete Response (CR) or Partial Response (PR) and the date of first documented radiographic progression or death due to any cause as per central review assessment.

Analysis population: PFS Full Analysis Set (PFS-FAS). Only participants for whom BOR was CR or PR and evaluable Duration of Response events (Progression or Death) included in the analysis.

Groups in this outcome

Main Study: 177Lu-PSMA-617 Plus Best Supportive/Best Standard of Care (BS/BSOC)

Patients randomized to receive the investigational product received 7.4 GBq (+/- 10%) 177Lu-PSMA-617 intravenously every 6 weeks (+/- 1 week) for a maximum of 6 cycles. Best supportive/best standard of care (BS/BSOC) might be used

Main Study: Best Supportive/Best Standard of Care (BS/BSOC) Alone

Patients randomized to this arm received best supportive/best standard of care (BS/BSOC) as determined by the investigator
