Outcome Measures

Primary Outcomes (1)

  • PSMA PET-CT detection of melanoma metastases

    The principal objective of the study is to investigate whether the diagnostic biomarker, prostate-specific membrane antigen (PSMA), can detect melanoma metastases using a PSMA PET/ CT.

    1 Year

Secondary Outcomes (1)

  • Compare FDG PET-CT & PSMA PET-CT

    1 Year

Study Arms (1)

PSMA PET-CT

EXPERIMENTAL

Within the two weeks prior to surgery, the patients will undergo both PSMA PET-CT \& FDG PET-CT scans at least 48 hours apart. The Investigational Medicinal Product (IMP) under investigation in this trial is 68Ga-PSMA. This is an imaging radionuclide tracer.

Drug: 68Ga-PSMA

Interventions

This is an imaging radionuclide tracer and is in chemical form. Up to 200 MBq. Route of administration is Intravenous.

PSMA PET-CT

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males ≥18 years of age
  • Biopsy proven first and recurrent metastatic melanoma with palpable nodal disease who have undergone a staging FDG PET-CT scan as part of routine clinical care and are scheduled for surgery for resection of the primary site

You may not qualify if:

  • Patients unable to give voluntary written informed consent to participate in this study
  • Patients not willing to complete all the study assessments
  • Patients who are females
  • Patients who are taking androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists.
  • Patients who have or have previously been diagnosed with prostate cancer
  • Patients who have had Lu-177 PSMA therapy or barium studies within a period of 10 days prior to undergoing PSMA PET-CT scanning
  • Patients not fluent in English
