Prostate Cancer Clinical Trial
A Study of Definitive Therapy to Treat Prostate Cancer After Prostatectomy
To assess the safety of treating men with oligometastatic prostate cancer with the following therapy: (1st) Systemic chemo-hormonal therapy with up to 6-months (~24 weeks) of adjuvant androgen deprivation and up to 6 cycles of chemotherapy, (2nd) definitive local tumor control with adjuvant radiation therapy, and (3rd) consolidative stereotactic radiation to oligometastatic lesions. The men will receive a total of 2 years of androgen deprivation. Androgen blockade will be the same throughout the course of treatment.
Adjuvant treatment (month 1 through ~6): All patients will be treated with up to 6 months of androgen deprivation, plus up to 6 cycles of docetaxel chemotherapy. Following docetaxel therapy, patients with a Prostate-specific antigen response of at least a 50% decrease from baseline, will proceed to maximum consolidative therapy.
Radiation (month 7 though ~11): After completion of adjuvant chemotherapy, the men will be treated with definitive local therapy with adjuvant radiation therapy (RT). After definitive local therapy, patients will be treated with consolidative stereotactic body radiation therapy (SBRT) to the metastatic sites (if present).
Follow up: Patients will continue on androgen deprivation for a total of 2 years. They will be followed clinically and monitored with serum testosterone and Prostate-specific antigen until 2-years after completion of ADT (Androgen deprivation therapy) treatment. Androgen blockade will be the same throughout the course of treatment.
Willing and able to provide written informed consent.
Age ≥ 18 years
Eastern cooperative oncology group (ECOG) performance status ≤2
Documented histologically confirmed adenocarcinoma of the prostate
Willing to undergo the following therapy: (1st) Systemic chemo-hormonal therapy with up to 6-months (~24 weeks) of neoadjuvant androgen deprivation and up to 6 cycles of chemotherapy, (2nd) definitive local tumor control with adjuvant radiation therapy, and (3rd) consolidative stereotactic radiation to oligometastatic lesions. Additionally, must be willing to be treated with a full two years of androgen deprivation.
Oligometastatic prostate cancer: Stage T1-4, N0-1 and/or M1a-b (up to 5 metastatic lesions- including bone lesions and non-regional lymph nodes seen on bone scan, contrast enhanced CT scan, or positron emission tomography PET scan)
Prior local non-surgical therapy to treat prostate cancer (e.g. radiation therapy, brachytherapy)
Prior therapy to a metastatic site.
Prior or ongoing systemic therapy for prostate cancer including, but not limited to:
Hormonal therapy (e.g. leuprolide, goserelin, triptorelin, degarelix)
CYP-17 (cytochrome P450 17α-hydroxy/17,20-lyase) inhibitors (e.g. ketoconazole)
Antiandrogens (e.g. bicalutamide, nilutamide)
Second generation antiandrogens (e.g. enzalutamide, abiraterone)
Immunotherapy (e.g. sipuleucel-T, ipilimumab)
Chemotherapy (e.g. docetaxel, cabazitaxel) *Note: may be enrolled if hormone therapy was recently initiated (<90 days duration)). In the event that hormone therapy was initiated prior to study enrollment, the clock for 2 years of androgen deprivation would begin at the time of therapy initiation, rather than at study enrollment.
Evidence of serious and/or unstable pre-existing medical, psychiatric or other condition (including laboratory abnormalities) that could interfere with patient safety or provision of informed consent to participate in this study.
Any psychological, familial, sociological, or geographical condition that could potentially interfere with compliance with the study protocol and follow-up schedule.
Abnormal bone marrow function [absolute neutrophil count (ANC)<1500/mm3, platelet count <100,000/mm3, hemoglobin <9 g/dL]
Abnormal liver function (bilirubin >ULN ( upper limit of normal); AST (aspartate aminotransferase), ALT (alanine transaminase) > 2.5 x upper limit of normal)
Creatinine clearance of ≥ 30 mL/min. CrCl (Creatinine clearance) should be calculated suing the Cockcroft-Gault formula.
Active cardiac disease defined as active angina, symptomatic congestive heart failure, or myocardial infarction within previous six months.
Prior history of malignancy in the past 3 years with the exception of basal cell and squamous cell carcinoma of the skin. Other malignancies that are considered to have a low potential to progress may be enrolled at discretion of PI.
