Pilot Trial of Chemohormonal Therapy Followed by Prostatectomy in High Risk Prostate Cancer
Study Details
Study Description
Brief Summary
This is a pilot multimodality treatment approach trial with androgen deprivation therapy in combination with docetaxel chemotherapy followed by radical prostatectomy in patients with newly diagnosed high-risk and oligometastatic prostate cancer. This study aims to evaluate the rates of complete pathologic response (pCR) at the time of prostatectomy as well as PSA response, time to PSA recurrence and safety and toxicity of the combination. This study will be heavily embedded with biomarker analyses of the tumor and tumor cells in circulation as well in the bone marrow before and after treatment and will also include imaging analyses using a novel positron emission tomography (PET) imaging technology.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Degarelix SC + bicalutamide + docetaxel Degarelix SC monthly x3 + bicalutamide 50mg orally QD x 14 wks + Docetaxel 75mg/m2 IV q 21 days x 3 |
Drug: Docetaxel
Docetaxel is a commercially marketed product that has been approved by the FDA for the treatment of metastatic prostate cancer. It is also approved for the treatment of other malignant disease, such as locally advanced or metastatic breast cancer that returns after any prior chemotherapy; locally advanced or metastatic non-small cell lung cancer that recurs after prior platinum-based chemotherapy. However, the FDA does not currently approve its use in patients with localized prostate cancer but no evidence of radiographic metastases.
Other Names:
Drug: Degarelix
Degarelix is a leuteinizing hormone-releasing hormone (LHRH) antagonist. Degarelix is administered at an initial dose of 240 mg subcutaneously (2 separate injections of 120mg each totaling 240 mg) two weeks prior to cycle 1 day 's 1 treatment with chemotherapy. The initial dose is followed by a maintenance dose of 80mg administered subcutaneously as a single injection every 28 days at cycle 2 day 1 (+/- 7 days) and cycle 3 day 10 (+/- 7 days)
Other Names:
Drug: Bicalutamide
The dose for bicalutamide tablets therapy in combination with an LHRH analog is one 50 mg tablet once daily (morning or evening), with or without food. It is recommended that bicalutamide tablets be taken at the same time each day. Treatment with bicalutamide tablets should be started at the same time as treatment with an LHRH analog.

Radiation: Ferumoxytol-enhanced MRI imaging
Ferumoxytol-enhanced MRI imaging will evaluate immune micro-environment in the prostate. Three subjects enrolled to the study will undergo the first ferumoxytol-enhanced MRI imaging within 21 days prior to start of hormonal therapy followed by second and final ferumoxytol-enhanced MRI at the conclusion of hormone therapy but prior to their prostatectomy.
