An Open-label Study Comparing Lutetium (177Lu) Vipivotide Tetraxetan Versus Observation in PSMA Positive OMPC.
The purpose of this study is to evaluate the efficacy and safety of lutetium (177Lu) vipivotide tetraxetan (AAA617) in participants with oligometastatic prostate cancer (OMPC) progressing after definitive therapy to their primary tumor. The data generated from this study will provide evidence for the treatment of AAA617 in early-stage prostate cancer patients to control recurrent tumor from progressing to fatal metastatic disease while preserving quality of life by delaying treatment with androgen deprivation therapy (ADT).
Study details:
All participants will be assessed for eligibility and will undergo baseline disease assessments including a mandatory gallium (68Ga) gozetotide (also known as \[68Ga\]Ga-PSMA-11) or piflufolastat (18F) ( also known as\[18F\]DCFPyL) PET/CT scan and conventional imaging (i. e. , CT/MRI and bone scans).
Piflufolastat (18F) PET/CT scan will be performed in countries where it is approved. Stereotactic Body Radiation Therapy (SBRT) will be administered to all metastatic Prostate Cancer (PC) lesions after randomization and before the start of treatment with AAA617 or observation. * The duration of SBRT procedures is approximately 3 weeks.
* For participants randomized to the investigational arm (AAA617), the treatment duration will be up to 4 cycles of AAA617. For participants randomized to the control arm (observation) the treatment duration will end at the last fraction of SBRT administration. * The visit frequency will be every week 1 and 3 of each of the 4 cycles and every 16 weeks thereafter (for both arms) until first event of disease progression (RECIST 1.
1). * The study duration is approximately 6. 5 years.

Time to prostate specific antigen (PSA) progression (TTPSAP) | Time to prostate specific antigen (PSA) progression (TTPSAP) is defined as time from randomization to first PSA progression 1. First PSA progression 1 is defined as a rising PSA confirmed on repeated measurement at least 3 weeks later, and at least greater than 25% and \>= 2 ng/mL above nadir or baseline, whichever is lower. In the absence of PSA progression, TTPSAP will be censored at the last PSA measurement. | From date of randomization until date of first PSA progression, assessed up to approximately 74 months |
Radiographic Progression Free Survival (rPFS) | Radiographic progression free survival (rPFS) is defined as the time from randomization to first documentation of confirmed radiographic progressive disease or death due to any cause (whichever occurs first) by conventional imaging (i.e., CT/MRI and bone scans) using RECIST 1.1. The rPFS will be analyzed based on BIRC and Investigator assessments respectively. | From date of randomization until date of radiographic progression or date of death from any cause, whichever comes first, assessed up to approximately 74 months |
Time to next therapy (local or systemic) | Time to next therapy (local or systemic) is defined as the time from randomization to initiation of the next line of therapy (local or systemic). Next-line therapy is defined as the first new (local or systemic) anti-neoplastic therapy initiated after discontinuation of study treatment regardless of end of treatment (EOT) reason. | From date of randomization until initiation of the next line of therapy (local or systemic), assessed up to approximately 74 months |
24-month prostate-specific antigen (PSA) progression free survival (PFS) | 24-month PSA PFS is defined as PSA PFS at 24 months.

PSA progression 2 is defined as a PSA concentration above the nadir (or baseline if lower) of \>= 0.5 ng/mL, confirmed by repeated measurement at least 3 weeks later. PSA PFS will be censored if no PSA PFS event is observed before the first to occur analysis cut-off date. The censoring date will be the date of the last adequate tumor assessment prior to cut-off. | From date of randomization until date of first documented PSA progression 2 or death from any cause, whichever occurs first, assessed up to approximately 74 months |
Time to symptomatic progression | Time to symptomatic progression is defined as time from randomization to the date of first documented event for any of the following, whichever occurs first: development of symptomatic skeletal event, escalation in cancer-related pain or worsening of disease-related symptoms leading to the initiation of a new systemic anticancer therapy, development of clinically significant symptoms due to local or regional tumor progression leading to surgery or radiation therapy. | From date of randomization until date of first documented symptomatic progression, assessed up to approximately 74 months |
Functional Assessment of Cancer Therapy - Prostate (FACT-P) Questionnaire | 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 FACTGeneral (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. | From date of randomization up till 42 day safety Follow-up, assessed up to approximately 74 months |

The FACT-RNT contains items assessing dry mouth, dry eyes, vomiting, diarrhea, constipation, loss of appetite, fatigue, impact of fatigue, bone pain, and isolation due to illness or treatment. FACT-RNT score range 0 to 60, with higher score indicating better quality of life. | From date of randomization up till 42 day safety Follow-up, assessed up to approximately 74 months |
Brief Pain Inventory - Short Form (BPI-SF) Questionnaire | The BPI-SF is a publicly available instrument to assess the pain and includes severity and interference scores. BPI-SF is an 11-item selfreport 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. | From date of randomization up till 42 day safety Follow-up, assessed up to approximately 74 months |
European Quality of Life (EuroQol) - 5 Domain 5 Level scale (EQ-5D- 5L) | 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. | From date of randomization up till 42 day safety Follow-up, assessed up to approximately 74 months |
Time to First Symptomatic Skeletal Event (TTSE) | Time to first symptomatic skeletal event (TTSSE) is defined as date of randomization to the date of first new SSE or death from any cause, whichever occurs first.
