ACTION: ACTInium-J591 Radionuclide Therapy in PSMA-Detected Metastatic HOrmone-Sensitive Recurrent Prostate CaNcer
Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the safety of combining Actinium- J591 with radiation therapy or with androgen deprivation therapy.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
|
Phase 1 |
Detailed Description
This is a two cohort pilot study for patients with hormone-sensitive prostate cancer after primary treatment +/- salvage treatment with metastases detected on PSMA-PET scan but equivocal, indeterminate or absent on conventional imaging.
Cohort 1 will have patients with Oligometastatic (low volume, between 1 and 5 metastases) disease and Cohort 2 will have patients with polymetastatic (high volume, ≥5 metastases) disease detected via PSMA PET.

Outcome Measures
Primary Outcome Measures
- Dose Limiting Toxicity (DLT) Rate [24 months]
A DLT will is defined as a grade 3 or higher hematologic adverse event or a grade 2 or higher non-hematologic adverse event deemed to be at least possibly related to study treatment. Adverse events will be assessed using CTCAE version 5. Patients will be observed for a DLT for 3 months from the second dose of actinium-J591.
- Change in Maximum Tolerated Dose (MTD) [3,6,12,18 and 24 months.]
Secondary Outcome Measures
- Progression Free Survival (PFS) on conventional Imaging [3 months]
- Progression Free Survival (PFS) on conventional Imaging [6 months]
- Progression Free Survival (PFS) on conventional Imaging [12 months]
- Progression Free Survival (PFS) on conventional Imaging [24 months]
- Progression Free Survival (PFS) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging. [3 months]
- Progression Free Survival (PFS) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging. [6 months]
- Progression Free Survival (PFS) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging. [12 months]
- Progression Free Survival (PFS) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging. [24 months]
- Changes in PSMA expression measured by comparison of SUV on PSMA PET scans before and after treatment [3, 6, 12, and 24 months]
- Change in Percentage of PSA decline [3, 6, 12, 15, 18, 21, and 24 months.]
Eligibility Criteria
Criteria
Inclusion Criteria:

-
Age ≥ 18 years
-
ECOG Performance Status 0-2.

External beam and/or brachytherapy to: Prostate alone, prostate and seminal vesicles, prostate and pelvic nodes, or radiation to all three sites.
-
Radical prostatectomy alone, radical prostatectomy plus postoperative radiotherapy to the prostate bed, or radical prostatectomy plus postoperative radiotherapy to the pelvic nodes.
-
Must meet study entry criteria based on the following diagnostic workup within 120 days prior to enrollment: • History and physical examination
-
99mTc bone scan (Must be negative or equivocal);
-
Either CT or MRI of pelvis +/- abdomen (Must be negative or equivocal);
-
PSMA PET scan (Must be positive with exception of local disease); Note: All 3 scans are mandatory (bone scan; CT/MR; PET)
-
Serum total testosterone >100 ng/dL within 120 days prior to enrollment.
-
Be willing to use effective contraception during the entire study period.
-
To have adequate organ and marrow function, as defined below:
-
- Absolute neutrophil count (ANC) of ≥2,000/mm3
-
- Hemoglobin ≥9 g/dL without need for transfusion
-
- Platelet count ≥150,000/mm3 and absent history or primary quantitative or qualitative platelet defect
-
- Serum creatinine of ≤1.5 x ULN or calculated creatinine clearance of ≥60 mL/min/1.73 m2 by Cockcroft-Gault (or determined by 24 hour urine collection)
-
- Serum total bilirubin ≤1.5 x ULN (unless due to Gilbert's syndrome, in which case direct bilirubin must be normal)
-
- Serum AST and ALT ≤1.5 x ULN.
Exclusion Criteria:
-
- Currently on androgen deprivation or anti-androgen therapy.
-
Definitive radiologic evidence of metastatic disease on conventional imaging, defined by one of the following:
