Prostate Cancer Clinical Trial
A Study of Stereotactic Body Radiation Therapy and Radium (Ra-223) Dichloride in Prostate Cancer That Has Spread to the Bones
Participants will either receive treatment with standard SBRT and the study drug Radium (Ra-223) dichloride, or standard SBRT alone.
Biopsy proven prostate adenocarcinoma
≥ 18 years old
Primary prostate tumor must have been treated with prior prostatectomy or definitive radiotherapy
Men with prior salvage radiotherapy to the prostate bed and/or locoregional lymph nodes are eligible assuming normalization of testosterone
Negative multi-parametric MRI and/or negative biopsy of the prostate (or prostate bed) within 60 days of enrollment
Pre-enrollment imaging (any bone imaging modality per institutional standard of care) demonstrates oligometastatic disease with 1-3 discrete metastatic lesions of the bone performed within 60 days of study enrollment; screening PSMA PET confirming 1-3 sites of oligometastatic disease performed within 60 days of enrollment.
All bony oligometastatic sites must be deemed appropriate to receive 3 fraction SBRT to a dose of 9 Gy x 3 at best judgment of treating radiation oncologist
Prostate specific antigen (PSA) ≥ 0.5 ng/mL but ≤ 50 ng/mL
Patients may have had prior androgen deprivation therapy (ADT) but must have normal testosterone levels (>100 ng/dL) at time of enrollment; patients with baseline low testosterone but no ADT exposure are eligible
Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
Subjects who have not had surgical removal of their prostate and have a partner of child bearing potential must agree to use condoms beginning at the signing of the consent until at least 6 months after the last dose of study drug. Because of the potential side effect on spermatogenesis associated with radiation, female partners of childbearing potential must agree to use a highly effective contraceptive method during and for 6 months after completing treatment. Examples of highly effective contraception options for women include implantable uterine devices (hormonal or non-hormonal), oral, patch and parenteral contraceptives (when taken as prescribed).
Adequate hematological, liver and renal function
Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L
Platelet count ≥ 100 x 10^9/L
Hemoglobin ≥ 10.0 g/dL
Total bilirubin level ≤ 1.5 x institutional upper limit of normal (ULN)
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x ULN
Creatinine ≤ 1.5 x ULN with normal creatinine clearance
Albumin > 25 g/L
Patient willing and able to comply with the protocol, including follow-up visits and examination
Pathological findings consistent with small cell and/or neuroendocrine carcinoma of the prostate or any other histology
Any metastatic site >5 cm in maximum diameter
Patients with documented castration resistant prostate cancer (CRPC)
Patients with any form of conventional, metabolic or molecular imaging (including PET imaging with PSMA, fluciclovine and/or FDG tracers) within 60 days of enrollment that demonstrate more than 3 discrete metastatic lesions
Patients with evidence of nonpelvic lymph nodal or any visceral metastases
Patients with evidence of progressing locoregional lymph nodes (prior lymphadenectomy or definitive/salvage RT to the pelvic lymph nodes is acceptable assuming no evidence of progression)
Patients with documented or suspected impending significant spinal cord compression defined as epidural spinal cord compression (ESCC) grade 2 or higher using the Bilsky scale
Patients with parenchymal brain metastases
Patient received any other investigational therapeutic agents or other anticancer therapeutics within 4 weeks prior to randomization
Major surgery within 30 days prior to start of study drug
Any prior systemic therapy with radionuclide agents (e.g., strontium-89, samarium-153, rhenium-186, rhenium-188 or Radium (Ra-223) dichloride) for the treatment of bony metastases
History of another malignancy within the previous 3 years except for the following:
adequately treated basal cell or squamous cell skin cancer
Any other serious illness or medical condition, such as but not limited to:
Any infection greater than National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v 5.0 Grade 2
New York Heart Association (NYHA) Class III or IV heart failure
Crohn's disease or ulcerative colitis
Bone marrow dysplasia or myelodysplastic syndrome
