ClinConnect Summary

This clinical trial is studying a new way to detect prostate cancer by combining two imaging tests: PSMA PET, which highlights cancer cells using a special tracer, and MRI, a detailed scan of the prostate. Researchers want to see if this combined approach is better than the usual methods doctors use now to find prostate cancer, especially in men who have signs that suggest they might have the disease.

Men who might be eligible for this study are those aged 18 or older who have a suspicion of prostate cancer based on recent MRI results or other risk factors, like high or rising PSA levels (a blood test related to prostate health), an abnormal prostate exam, a strong family history of prostate cancer, or certain blood markers that suggest higher risk. Participants should not have had a prostate biopsy before and must be healthy enough to take part in the study. If eligible, participants will undergo imaging tests and may have a prostate biopsy, which involves taking small samples of tissue to check for cancer. The study will follow them over time to compare how well this new combined imaging method works compared to the standard tests. It’s important to note that the trial is not yet recruiting and is focused on men who have not yet been treated for prostate cancer.

Eligibility criteria

  • Inclusion Criteria:
  • 1. Male, at least 18 years old.
  • 2. Have a clinical suspicion of PCa, and will undergo template biopsy, based on either: an initial MRI examination (PI-RADS 3-4) within 3 months (92 days) before enrollment, or no MRI evidence (PI-RADs 1-2) within 3 months (92 days) before enrollment, but a clinician indicated intent to proceed with template biopsy due to non-imaging risk factors.
  • These are non-imaging risk factors that would lead a patient to be considered for a template biopsy (including but not exclusive to):
  • 1. Persistently elevated or rising PSA i. PSA ≥ 3.0 ng/mL ii. Rising PSA velocity (e.g., \>0.35-0.75 ng/mL/year over 2-3 years) is also considered suspicious, especially in men with PSA\<10ng/mL.
  • 2. High PSA density (PSAD) i. PSA density \> 0.15 ng/mL/cm³ is considered high-risk for csPCa. ii. Calculated as PSA (ng/mL) divided by prostate volume (from MRI).
  • 3. Abnormal digital rectal examination (DRE) i. abnormal findings include:
  • 1. Nodules
  • 2. Induration
  • 3. Asymmetry
  • 4. Fixation of the prostate ii. An abnormal DRE in any PSA range (including \<3 ng/mL) increases cancer suspicion.
  • b) Strong family history of prostate cancer: i. First-degree relative (father or brother) with PCa 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) c) Other high-risk biomarkers i. 4Kscore: ≥ 7.5-10% risk of high-grade PCa ii. PHI (Prostate Health Index): ≥ 35 suggests elevated risk iii. Prostate Cancer Antigen 3 (PCA3) Score: ≥ 35 considered positive and associated with increased risk of PCa.
  • iv. Any other established biomarker with values in the high-risk range d) 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 participants. 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 had prior treatment for PCa or prior diagnosis of csPCa.
  • 2. Obvious metastatic disease on prior conventional imaging.
  • 3. 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
