Brief Summary:
The primary objective of this study is to compare the two alternate primary endpoints of radiographic progression-free survival (rPFS) and overall survival (OS) in patients with progressive PSMA-positive mCRPC who receive 177Lu-PSMA-617 in addition to best supportive/best standard of care versus patients treated with best supportive/best standard of care alone.

Condition or disease Intervention/treatment Phase
Prostate Cancer Drug: 177Lu-PSMA-617 Other: Best supportive/best standard of care Phase 3

Detailed Description:

Patients with PSMA positive scans will be randomized in a 2:1 ratio to receive either 177Lu-PSMA-617 plus best supportive/best standard of care or to receive best supportive/best standard of care only. Best supportive/best standard of care will be determined by the treating physician/investigator but will exclude investigational agents, cytotoxic chemotherapy, other systemic radioisotopes, and hemi-body radiotherapy. Novel androgen axis drugs [NAADs] (such as abiraterone or enzalutamide) are allowed.

The study is open-label and patients will be monitored throughout the 6 to 10-month treatment period for survival, disease progression, and adverse events.

A long-term follow-up period will include the collection of rPFS survival and information about new treatments, responses to new treatments, adverse events assessment, as well as blood for hematology and chemistry testing. During follow-up, patients will be contacted every 3 months (+/- 1 month) via phone, email, or letter for 24 months or until 508 deaths have occurred.

An End of Treatment visit should occur once a patient discontinues the treatment part of the study for any reason (patient or investigator decision, going on to long term follow up, etc.). This visit should occur approximately 30 days from the last dose of 177Lu-PSMA-617 or the date of the best supportive/best standard of care end of treatment decision (whichever occurs later), but before the initiation of subsequent anti-cancer treatment, outside of what is allowed on study.

The planned enrollment for this study is 814 patients.

A dosimetry, PK and ECG sub-study will be conducted in a non-randomized cohort (177Lu-PSMA-617 plus best supportive/best standard of care) of approximately 30 patients at sites in Germany to provide a more complete assessment of the safety aspects of 177Lu-PSMA-617. In order to not bias the results obtained from randomized patients in the main study, the data of the sub-study patients will be analyzed descriptively and not considered in the primary and secondary analysis of the main study.

    EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. 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.

  11. Functional Assessment of Cancer Therapy - Prostate (FACT-P) Questionnaire [ Time Frame: From date of randomization till 30 days safety fup, assessed up to 32 months (actual final OS analysis) ]
    FACT-P assesses symptoms/problems related to prostate carcinoma and its treatment. It is a combination of the FACT-General + the Prostate Cancer Subscale (PCS). The FACT-General (FACT-G) is a 27 item Quality of Life (QoL) measure that provides a total score as well as subscale scores: Physical (0-28), Functional (0-28), Social (0-28), and Emotional Well-being (0-24). The total score range is between 1-108, higher scores indicates better for total score and subscale scores. PCS is a 12-item prostate cancer subscale that asks about symptoms and problems specific to prostate cancer (Range 0-48, higher scores better). The FACT-P total score is the sum of all 5 subscale scores of the FACT-P questionnaire and ranges from 0-156. Higher scores indicate higher degree of functioning and better quality of life.

  12. Brief Pain Inventory-short Form (PBI-SF) [ Time Frame: From date of randomization till 30 days safety fup, assessed up to 32 months (actual final OS analysis) ]
    The BPI-SF is a publicly available instrument to assess the pain and includes severity and interference scores. BPI-SF is an 11-item self report questionnaire that is designed to assess the severity and impact of pain on daily functions of a participant. Pain severity score is a mean value for BPI-SF questions 3, 4, 5 and 6 (questions inquiring about the extent of pain, where the extent is ranked from 0 [no pain] to 10 [pain as bad as you can imagine]). Pain severity progression is defined as an increase in score of 30% or greater from baseline without decrease in analgesic use.
