This phase II trial studies how well 68Ga-PSMA-11 positron emission tomography (PET)/computed tomography (CT) works in detecting the spread of cancer to the bones (bone metastasis) in patients with prostate cancer and increased PSA after treatment (biochemical recurrence) during androgen deprivation therapy. Diagnostic procedures, such as 68Ga-PSMA-11 PET/CT, may help find and diagnose prostate cancer and find out how far the disease has spread.
PRIMARY OBJECTIVE:
I. To compare the per-patient detection rate of 68Ga-PSMA-11 PET/CT versus bone scan (BS)/CT for M1b in patients treated with androgen deprivation therapy (ADT) who are referred for the imaging evaluation of disease progression.
SECONDARY OBJECTIVES:
I. To compare the number of lesions rated as positive for bone metastases between the two imaging tests.
II. To compare the detection rate of 68Ga-PSMA PET/CT versus BS/CT for all M1 disease (M1a or M1b or M1c).
III. To compare the positive predictive value (PPV) per-patient in patients with lesion validation (follow-up imaging or biopsy).
OUTLINE:
Patients receive gallium Ga 68 gozetotide intravenously (IV). After 50-100 minutes, patients undergo whole body PET/CT.

| Per-patient detection rate of gallium Ga 68 gozetotide (68Ga-PSMA-11) positron emission tomography (PET)/computed tomography (CT) | 68Ga-PSMA-11 PET will be compared to bone scan/CT for M1b disease in prostate cancer patients progressing during androgen deprivation therapy. Patients who have at least one positive bone lesion will be rated positive. Patients will be treated as binary categorization. The analysis of the primary objective will utilize the McNemar's test to compare the detection rate between the imaging techniques. | Up to 4 years |
| Measure | Description | Time Frame |
|---|---|---|
| Number of lesions found by PSMA PET and bone scan + CT | Will be compared using a paired samples t-test. | Up to 4 years |
| Rate of M1 detection | Will be compared between the two modalities, defined as the number of patients with positive finding(s) for M1 disease (M1a or M1b or M1c), will utilize the McNemar's test for paired proportions. |

| Per-patient positive predictive value (PPV) | Per-patient PPV estimates (with 95% confidence interval), defined as the number true positive findings the total number of positive cases (TP + FP). The lesions will be considered true positive on the basis of biopsy information, follow-up imaging, or changes in prostate specific antigen (PSA) levels. This information will only be available in a small subset of patients. | Up to 4 years |
| PSA progression-free survival (PFS) | Univariate Cox proportional hazards models for PFS will be constructed with models containing various patient characteristics as well as PSMA PET parameters and bone scan parameters. Hazard ratios with 95% confidence intervals as well as p-values will be tabulated. Next, will explore multivariate models (using LASSO variable selection) including terms for important baseline characteristics as well as PSMA parameters or bone scan parameters and will extract the survival concordance indices from each of these models and compare them. | Up to 4 years |
| Overall survival (OS) | Univariate Cox proportional hazards models for OS will be constructed with models containing various patient characteristics as well as PSMA PET parameters and bone scan parameters. Hazard ratios with 95% confidence intervals as well as p-values will be tabulated. Next, will explore multivariate models (using LASSO variable selection) including terms for important baseline characteristics as well as PSMA parameters or bone scan parameters and will extract the survival concordance indices from each of these models and compare them. | Up to 4 years |
