Overview
The aim for this study is to investigate the ability of 64Cu-SAR-bisPSMA PET/CT to detect recurrence of prostate cancer
Eligibility
Inclusion Criteria:
- At least 18 years of age.
- Signed informed consent.
- Life expectancy ≥ 6 months as determined by the Investigator.
- Histologically confirmed adenocarcinoma of prostate per original diagnosis and completed subsequent definitive therapy.
- Participant potentially eligible for salvage therapy with curative intent.
- PSA level after definitive therapy:
- Post-radical prostatectomy: Detectable or rising PSA that is ≥ 0.2 ng/mL with a confirmatory PSA ≥ 0.2 ng/mL (per AUA recommendation) or
- Post-radiation therapy, cryotherapy, or brachytherapy: Increase in PSA level that is elevated by ≥ 2 ng/mL above the nadir (per ASTRO-Phoenix consensus definition).
- Participant willing to undergo biopsy of a 64Cu-SAR-bisPSMA PET-positive lesion for
histological confirmation of PC, where this is safe and feasible.
- An Eastern Cooperative Oncology performance status of 0-2.
Exclusion Criteria:
- Participants who received investigational agent within 5 biological half-lives prior to Day 1.
- Participants administered any high energy (>300 KeV) gamma-emitting radioisotope within 5 physical half-lives prior to Day 1.
- Previous systemic therapy for PC (with the exception of neoadjuvant and adjuvant systemic therapy as part of the definitive therapy).
- Ongoing treatment or treatment within 6 months of Day 1 with any systemic therapy (e.g. any investigational therapy, androgen-deprivation therapy, antiandrogen, gonadotropin-releasing hormone, luteinizing hormone-releasing hormone agonist or antagonist, chemotherapy, immunotherapy or radiotherapy) for PC.
- Known or expected hypersensitivity to 64Cu-SAR-bisPSMA or any of its components.
- Any serious medical condition or extenuating circumstance (including receiving the investigational product or not capable of having a PET scan) which the investigator feels may interfere with the procedures or evaluations of the study.
