NCT05562791

Brief Summary

The purpose of this study is to see whether 68Gallium PSMA-PET/CT scans are an effective way to detect sites of cancer in people with metastatic bladder cancer or skin cancer. The study researchers want to learn if a 68Gallium PSMA PET/CT scan will work better, the same, or not as well as the PET/CT scans doctors usually use for imaging bladder cancer or skin cancer (FDG-PET/CT scan).

Outcome Measures

Primary Outcomes (2)

  • Define the proportion of patients with 1 or more lesions detectable by 68Gallium PSMA-PET/CT for Urothelial Carcinoma

    If 6 of 10 patients have at least one lesion identified both on standard of care FDG PET/CT and also detected on 68Gallium PSMA-PET/CT, this imaging modality will be worthy of further exploration in metastatic UC.

    1 year

  • Define the proportion of patients with 1 or more lesions detectable by 68Gallium PSMA-PET/CT for Melanoma

    If 6 of 10 patients have at least one lesion identified both on standard of care FDG PET/CT and also detected on 68Gallium PSMA-PET/CT, this imaging modality will be worthy of further exploration in metastatic Melanoma.

    1 year

Study Arms (2)

Patients with metastatic urothelial carcinoma lesions

EXPERIMENTAL

Patients will initially undergo a standard of care FDG PET with diagnostic CT scan followed by an investigational 68Ga PSMA PET/CT scan.

Drug: [68Ga]PSMADiagnostic Test: PET/CT imaging

Patients with melanoma lesions

EXPERIMENTAL

Patients with melanoma who have 1 or more radiographically assessable metastatic lesions on standard of care imaging will undergo a 68Gallium PSMA-PET/CT and standard of care imaging (either FDG PET or CT scan).

Drug: [68Ga]PSMADiagnostic Test: PET/CT imaging

Interventions

68Gallium PSMA-PET/CT imaging within 10 days after standard of care FDG-PET/CT.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with histologically confirmed metastatic urothelial carcinoma with extrapelvic nodal and/or visceral sites of disease (including lung, liver, bone, or soft tissue)
  • At least 1 lesion assessable by FDG PET/CT according to RECIST and PERCIST guidelines where applicable, that are determined suspicious for metastasis by an MSKCC attending radiologist or nuclear medicine physician.
  • Karnofsky performance status ≥50% (or ECOG/WHO ≤2)
  • Participant is ≥18 years of age
  • Patient must be able to understand and is willing to sign a written informed consent document
  • Patients with histologically confirmed metastatic melanoma
  • At least 1 metastatic lesion assessable by CT or FDG PET/CT according to RECIST that is determined to be suspicious for metastasis by an MSKCC attending radiologist or nuclear medicine physician
  • ECOG \<= 2
  • Participant is \>= 18 years of age
  • Patient must be able to understand and is willing to sign a written informed consent document

You may not qualify if:

  • Patients with pelvic node-only metastatic disease. If the patient has lymph node only disease, at least one PET-assessable node must be located outside of the pelvis
  • Patients with bone only disease
  • Unable to lie flat, still, or to tolerate a PET scan
  • Patient undergoing active treatment for non-urothelial malignancy, other than skin basal cell or cutaneous superficial squamous cell carcinoma that has not metastasized.
  • Patients on a therapeutic clinical trial where PSMA imaging would interfere with the conduct of the trial
  • Patients undergoing active surveillance with a known history of non-urothelial malignancies
  • Women who are pregnant. All women of childbearing potential must have a documented negative pregnancy test.
  • Unable to lie flat, still, or tolerate PET scan.
  • Patient is on another therapeutic trial where PSMA imaging would interfere with the conduct of the trial.
  • Women who are pregnant. All women of childbearing potential must have a documented negative pregnancy test.
