PSMA PET Combined With MRI for the Detection of PCa

Summary

This is an open label, longitudinal Phase 3 study of prostate specific membrane antigen (PSMA) positron emission tomography (PET) combined with magnetic resonance imaging (MRI) compared to standard of care (SOC) for the detection of prostate cancer (PCa).

Eligibility

Inclusion Criteria:

1. Male, at least 18 years old.
2. Have a clinical suspicion of csPCa, and indicated for template biopsy after having received an MRI demonstrating PI-RADs 1 to 4 within 6 months of enrollment and/or have non-imaging risk factors (including but not exclusive to):

   a) Persistently elevated or rising PSA b) High PSA density c) Abnormal digital rectal examination (DRE) d) Strong family history of prostate cancer: i. First-degree relative (father or brother) with csPCa ii. Any relative diagnosed at \<65 years of age iii. Multiple affected relatives iv. Known hereditary cancer syndromes (e.g. BReast CAncer gene \[BRCA\]1/2, Homeobox protein Hox-B13 \[HOXB13\] mutations) e) Other high-risk biomarkers: i. 4Kscore ii. PHI (Prostate Health Index) iii. High Prostate Cancer Antigen 3 (PCA3) iv. Any other established biomarker with values in the high-risk range f) Clinical presentation: i. Symptoms suggestive of locally advanced disease (e.g. urinary obstruction, bone pain) ii. Prior negative MRI with ongoing clinical concern
3. Prostate biopsy naïve.
4. Eastern Cooperative Oncology Group performance status (ECOG PS) ≤2 per FDA guidelines.
5. Have the capacity to understand the study and be able and willing to comply with all protocol requirements.
6. Provides consent for anatomical template with/without targeted biopsy based on clinical risk, MRI and PSMA PET result.
7. Participants must comply with the radiation protection rules (including hospital admissions and isolation) that are used by the treating institution to protect their contacts and the general public, especially if a female partner of the participant is or could be pregnant.
8. Must agree to practice adequate precautions to prevent pregnancy in a female partner and to avoid potential problems associated with radiation exposure to the unborn child (Recommendations related to contraception and pregnancy testing in clinical trials Version 1.1, (CTFG \[Clinical Trial Facilitation Group\], 2020). Details of contraceptive measures to be taken by male participants and their female partners are described in Appendix 4 of the Protocol.

Exclusion Criteria:

Participants are excluded from the study if any of the following criteria apply:

1. Has prior diagnosis of csPCa
2. Previous diagnosis of cancer of any primary origin (excluding basal cell carcinoma or squamous cell carcinoma of the skin that has undergone potentially curative therapy).

4\. Active prostate infection, or urinary test results suggestive of an active urinary tract infection, evident on medical history, within 4 weeks of enrollment.

5\. Prior pelvic irradiation 6. Demonstrate radiographic findings of PI-RADS 5. 7. Has abnormalities in physical examination and protocol-specified clinical laboratory tests during the Screening Period that, in the judgment of the investigator, could affect safety or compliance; and/or is deemed not suitable for participating in this trial in the opinion of the investigator.

8\. Unable to understand or is unwilling to sign a written informed consent document or to follow investigational procedures in the opinion of the investigator. 9. Is unable to attain or remain in a supine position while a PET/CT scan is being performed or unable to tolerate a PET/CT scan 10. Unable or unwilling to undergo clinical prostate biopsy, has known allergies, hypersensitivity, or intolerance to the investigational drug/comparator or its excipients.

11\. Have prior use of radionuclides with an interval of less than 10 effective half-lives before the administration of 68Ga-PSMA-11.

12\. Is participating or plans to participate in any experimental drug or device trial during the study period that are considered outside of therapeutic SOC. Studies involving modifications of sequencing or timing of therapeutic regimens/interventions would be deemed eligible to enroll.
