Arm Intervention/treatment
Experimental: 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

Patients who were alive without radiographic progression at the analysis data cut-off were censored for rPFS at the time of their last evaluable radiographic assessment. Date of censoring for rPFS: 1) The censoring date was the date when the last evaluable radiographic assessment (CT/MRI/bone scan) determined a lack of progression; 2) If there were no evaluable assessments, censoring occurred at the date of randomization; 3) Patients who had 2 or more consecutive missed tumor assessments immediately prior to PD or death were censored at the date of the last evaluable tumor assessment prior to those missing tumor assessments.

  2. Overall Survival (OS) [ Time Frame: From date of randomization until date of death from any cause, assessed up to 43 months (Final OS analysis cut-off date = 27-Jan-2021) ]
    Overall Survival (OS) was defined as the time (in months) from the date of randomization to the date of death due to any cause. If the patient was not known to have died, then OS was censored. The censoring date was date of the last study visit, or contact, until the cut-off date. The cut-off date was not used for last contact date, unless the patient was seen or contacted on that date.

    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.

    Time to first Symptomatic Skeletal Event (SSE) was defined as the time (in months) from the date of randomization to the date of the SSE or death from any cause. The SSE date was the date of first new symptomatic pathological bone fracture, spinal cord compression, tumor-related orthopedic surgical intervention, requirement for radiation therapy to relieve bone pain, or death due to any cause, whichever occurred first. SSE data for this endpoint were collected up through EOT visit. The censoring date was date of the last study visit (on or before the EOT visit).

    The BPI-SF is a generic pain assessment tool used in research and practice for pain assessment in musculoskeletal conditions. The higher the BPI-SF score, the worse the pain. The BPI-SF consists of 4 questions regarding pain intensity (worst pain intensity, least pain intensity, average pain intensity and pain right now), 2 questions on the use of analgesics, and 7 questions on how the level pain has interfered with the subject's life (General Activity, Mood, Walking Ability, Normal Work, Relations with other people, Sleep, Enjoyment of Life). Intensity items consist of an 11-response rating scale scored from 0 ("No Pain") to 10 ("Pain As Bad As You Can Imagine"). BPI-SF Pain intensity is the mean of non-missing items of the 4 individual scales, if there are 3 or more items not missing; otherwise this scale is set to missing.

  19. Change From Baseline in BPI-SF (Brief-Pain Inventory - Short Form) Pain Interference Scale [ Time Frame: Baseline (BL), Cycle 2 to Cycle 13 (Week 1 Day 1), End of Treatment (EoT) (cycle duration for Cycle 1-6 = 6 weeks and for Cycle 7 and beyond = 12 weeks) ]
    "The BPI-SF is a generic pain assessment tool used in research and practice for pain assessment in musculoskeletal conditions. The higher the BPI-SF score, the worse the pain. The BPI-SF consists of 4 questions regarding pain intensity (worst pain intensity, least pain intensity, average pain intensity and pain right now), 2 questions on the use of analgesics, and 7 questions on how the level pain has interfered with the subject's life (General Activity, Mood, Walking Ability, Normal Work, Relations with other people, Sleep, Enjoyment of Life). Interference items consist of scores from 0 ("Does Not Interfere") to 10 ("Completely Interferes"). BPI-SF Interference scale is the mean of non-missing items of the 7 items on pain interference, if there are 4 or more items not missing; otherwise this scale is set to missing."

Higher scores indicate higher degree of functioning and better quality of life.

  22. Time to Worsening in EQ-5D-5L Utility Score [ Time Frame: From date of randomization until date of End of Treatment (EoT), assessed up to 43 months (Final OS analysis cut-off date = 27-Jan-2021) ]

  23. Change From Baseline in the European Quality of Life (EuroQol) - 5 Domain 5 Level Scale (EQ-5D-5L) Utility Score [ Time Frame: Baseline (BL), Cycle 2 to Cycle 13 (Week 1 Day 1), End of Treatment (EoT) (cycle duration for Cycle 1-6 = 6 weeks and for Cycle 7 and beyond = 12 weeks) ]
    The EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1= no problems, 2= slight problems, 3=moderate problems, 4= severe problems, and 5= extreme problems. Higher scores indicated greater levels of problems across each of the five dimensions. A utility score was obtained by using a weighted combination of the levels of the five dimension-scales. The weights were based on value sets which were country-specific for the U.K. Utility scores ranges from the lowest possible score for a living patient of -0.594 (when all responses are '5') to 1 (when all responses are '1').If a patient died, he was assigned a score of 0 on the date of death.

  24. Change From Baseline in the European Quality of Life (EuroQol) - 5 Domain 5 Level Scale (EQ-5D-5L) EQ-VAS [ Time Frame: Baseline (BL), Cycle 2 to Cycle 13 (Week 1 Day 1), End of Treatment (EoT) (cycle duration for Cycle 1-6 = 6 weeks and for Cycle 7 and beyond = 12 weeks) ]
    The EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ VAS records the patient's self-rated health on a vertical visual analogue 0-100 scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The higher the EQ-VAS score, the better the QoL.

  25. Number of Participants Hospitalized as In-patient [ Time Frame: From date of randomization till 30 days safety fup, assessed up to 43 months (Final OS analysis cut-off date = 27-Jan-2021) ]

    The duration of time in hospital following 177Lu-PSMA-617 administration (hours) was the time span of patient discharged as captured on the 177Lu-PSMA-617 administration Case Report Form (CRF).

  27. Concomitant Drug Use for Health Economics Analysis [ Time Frame: From date of randomization till 30 days safety fup, assessed up to 43 months (Final OS analysis cut-off date = 27-Jan-2021) ]

  28. Therapeutic Interventions for Health Economics Analysis [ Time Frame: From date of randomization till 30 days safety fup, assessed up to 43 months (Final OS analysis cut-off date = 27-Jan-2021) ]
    The list of therapeutic interventions was pre-specified and flagged prior to the pre planned analyses as captured on: 1) the concurrent radiotherapy CRF page to include local external beam radiotherapy (inclusive of palliative external radiation), 2) on the concomitant medication/therapy CRF page to include blood transfusion (full blood or derivates).
