The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built

Investigator standing0/100
No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Eligibility as written in the registry

Inclusion Criteria: * Male \>=18 years old. * Able to provide written informed consent and comply with the study procedures. * Participants with advanced and/or metastatic histologically or cytologically confirmed adenocarcinoma of the prostate without small cell histology or neuroendocrine transformation. * Serum testosterone levels less than or equal to (\<=) 0.5 nanograms per millilitre (ng/mL) (\<=1.73 nanomoles per litre \[nmol/L\]) at screening if on an androgen receptor prostate inhibitor in combination with Androgen Deprivation Therapy (ADT). * Progression (as defined below) after the receipt of at least one or more approved second-generation androgen-receptor-pathway inhibitors with or without a prior course of taxane therapy, as long as the subject has not received more than three lines of therapy in the CRPC setting. If a subject is known positive for any of the specific gene mutations of BRCA1/2, PALB2, or HRD and chose not to receive an approved PARP-inhibitor they are eligible for the study. Documented progressive disease at screening as assessed by the Investigator with at least one of the following criteria: * Serum/plasma PSA progression defined as 2 consecutive increases in PSA over a previous reference value measured at least 1 week apart. 1.0 ng/mL is the minimal starting value if confirmed rise is only indication of progression. * Radiographic disease progression in soft tissue based on response evaluation criteria in solid tumors (RECIST) v1.1 criteria with or without PSA progression as per prostate cancer working group 3 (PCWG3). * Radiographic disease progression in bone defined as the appearance of 2 or more new bone lesions on a bone scan as per PCWG3 with or without PSA progression. * Able to undergo general anesthesia, MAC anesthesia, or conscious sedation. * Eastern Cooperative Oncology Group (ECOG) performance status of less than (\<) 2. * Life expectancy \>=6 months * Last dose of previous anticancer therapy (excluding hormonal therapy) must by 28 days prior to first study treatment. For subjects who previously received lutetium Lu 177 vipivotide tetraxetan (Pluvicto®), the last dose must have been administered \> 90 days prior to first study treatment. Subjects may remain on ADT and/or androgen receptor pathway inhibitor at time of study entry, per Investigator discretion. * Resolution of all acute toxic effects (excluding alopecia) of any prior anticancer therapy. * For males with female partners of childbearing potential, even if surgically sterilized (that is \[i.e.\], status post vasectomy), who agree to practice: 1. effective barrier contraception during the treatment period and through 120-150 days after last dose, OR 2. true abstinence, when this is in line with the preferred and usual lifestyle of the participants. Periodic abstinence (for example \[e.g.\], calendar, ovulation, symptothermal, post ovulation methods), withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together. * Must have at least one measurable lesion per RECIST v1.1 at time of screening. * Must have at least one lesion suitable for SYNC-T Therapy identified by radiographic imaging as defined below: * Soft tissue lesion (e.g., prostate, lung) must be at least 1 cm in at least two dimensions. * Lymph node lesion of at least 1.5 cm (short axis) or 1.0 cm if positive per PET scan. * Exophytic component of a bone lesion that is measurable per RECIST v1.1. Soft tissue and lymph nodes must be demonstrable on CT/MRI and accessible either transperineally or percutaneously to permit tumor biopsy, cryolysis, and immunotherapy infusion. The eligible tumor lesion for intratumoral infusion cannot be a tumor that is adjacent to vital structures such as major nerves or blood vessels or at risk of airway compromise in the event of post-infusion tumor swelling/inflammation. * Participants receiving bone resorptive therapy must be on stable doses for at least 42 days prior to the oncolysis. * In the opinion of the Investigator, there is no other meaningful life prolonging therapy option available, or the participant refuses other therapy, outside of anti-hormonal therapy. * Adequate bone marrow, renal, and hepatic function. * Participants agrees to provide tumor tissue and undergo an on-treatment tumor biopsy.

Participants with a history of autoimmunity that has not required systemic immunosuppressive therapy or does not threaten vital organ function including CNS, heart, lungs, kidneys, skin, and GI tract will be allowed. * Other immunodeficiency diseases that in the opinion of the Investigator, with consultation with Medical Monitor, could compromise the participant or limit treatment efficacy. * Uncontrolled or unmanaged diabetes, hypersensitivity, or other illness or disease that in the opinion of the Investigator, with consultation with Medical Monitor (MM), makes the subject a poor candidate. * History of bone marrow/stem cell transplant. * Participants having human immunodeficiency virus (HIV) infection or acquired immune deficiency syndrome (AIDS) are not eligible for enrollment. * Active coronavirus disease-2019 (COVID-19) infection or tests positive for COVID-19 a day before or the day of planned study treatment. * Participants who have active viral (any etiology) hepatitis are excluded. * Participants with serologic evidence of chronic hepatitis B virus (HBV) infection (defined by a positive hepatitis B surface antigen \[HBsAg\] test and a positive hepatitis B core antibody (anti-HBc) test) who have a viral load below the limit quantification (HBV deoxyribonucleic acid \[DNA\] titer \<1000 copies per milliliters \[cps/mL\] or 200 international units per milliliter \[IU/mL\]) and are not currently on viral suppressive therapy may be eligible and should be discussed with the Sponsor's Medical Monitor. * Participants with a history of hepatitis C virus (HCV) infection should have completed curative antiviral treatment and have a viral load below the limit of quantification are eligible for study entry. Known or suspected hepatitis C infection which has not been treated and cured are not eligible. Known or suspected hepatitis C currently on treatment with an undetectable viral load are eligible. Patients with a history of hepatitis C virus (HCV) infection should have completed curative antiviral treatment and have a viral load below the limit of quantification are eligible for study entry. * Participants with complications or contraindications related to the liver, including intrahepatic biliary ductal dilation, uncorrectable bleeding diathesis, and decompensated liver failure. * Breast cancer gene (BRCA) mutation testing will be required for participants not previously treated with a PARP inhibitor, unless BRCA status is established prior to screening. If PARP-positive and participants agree to PARP therapy, they will be ineligible. * Any condition(s) that, in the opinion of the Investigator, would increase the risk for toxicities from study treatment, or interfere with participants compliance or conduct of this study. * Known visceral metastases, except for lung metastases. * Known substance abuse or medical, psychological, or social conditions that may interfere with patient's participation. * Participants who have received both chemotherapy and lutetium Lu 177 vipivotide tetraxetan (Pluvicto) in the CRPC setting.
