NCT ID: NCT02430480

Last Updated: 2025-07-16

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 39 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-06-03
• Study Completion Date: 2024-06-11

Brief Summary

Background:

• There are several ways to treat prostate cancer. Researchers want to see how well a certain kind of imaging helps detect prostate cancer. They also want to see if a particular drug combination used before surgery will benefit people with prostate cancer that hasn't spread in the body (non-metastatic). The combination will be androgen deprivation therapy and enzalutamide.
• The combination of androgen deprivation therapy and enzalutamide has been shown to make patients with advanced (metastatic disease) live longer. The investigators want to see if using it earlier can increase cure rate of surgery and identify genetic or molecular characteristics that are associated with better outcomes.

Objectives:

• To develop better ways of detecting prostate cancer before and after pre-operative treatment.

Eligibility:

• Men at least 18 years old with non-metastatic prostate cancer. They must be candidates for a radical prostatectomy.

Design:

• Participants will be screened with medical history, physical exam, and blood tests. They will have scans and X-rays.
• Before starting the study drugs, participants will have:
• Vital signs taken, medical history, and blood tests.
• Electrocardiogram (ECG) heart test, with patches stuck on the skin.
• Small piece of tumor removed (biopsy) using image guidance from magnetic resonance imaging (MRI) and ultrasound.
• 3T multi-parametric magnetic resonance imaging (mpMRI). Participants will lie on a table that slides into a metal cylinder. A probe will be inserted in the rectum. They will be in the scanner for about 60 minutes, lying still. The scanner makes loud knocking sounds. Participants will get earplugs.
• Participants will take the 2 study drugs for 6 months.
• Enzalutamide is taken as 4 pills once a day.
• Androgen deprivation therapy is given by injection 2 times over 6 months.
• During these 6 months, participants will visit the clinic monthly. They will have physical exam, vital signs, and blood drawn.
• After finishing the study drugs, participants will have another 3T mpMRI. Then they will have prostate removal surgery.

Detailed Description

Background:

• Most men diagnosed with prostate cancer will present with intermediate or high-risk disease
• Many develop castrate resistant prostate cancer (CRPC) as curative strategies are often unsuccessful
• Treatment options typically involve radical prostatectomy (RP) or radiation therapy (RT) in combination with androgen deprivation therapy (ADT)
• Even when cancers are initially sensitive to ADT, resistance ultimately emerges either through clonal selection or through a variety of adaptive mechanisms (secondary resistance).
• The recent introduction of novel androgen pathway inhibitors offers an opportunity to potentially improve the cure rate of men with intermediate and high risk localized prostate cancer
• There remains a great need for improved techniques to determine mechanisms of treatment response and resistance.

Objectives:

-To test the feasibility of multi parametric magnetic resonance imaging (mpMRI) for the localization and detection of focal prostate cancer both before and after pre-operative treatment with ADT and enzalutamide.

Eligibility:

• Patients with nonmetastatic castration sensitive prostate cancer with intermediate or high-risk features
• Patients with testosterone levels greater than or equal to 100 ng/dL.
• Eastern Cooperative Oncology Group (ECOG) 0-1.

Design:

• Patients will be treated with ADT and enzalutamide for 6 months
• Two 3T mpMRI endorectal examinations (One at screening and after 6 month of treatment)
• Screening biopsy (magnetic resonance (MR)/ultrasound (US) guided) samples
• Standard of care prostatectomy (RP) following post treatment mpMRI
• All tumor specimens will undergo genomic analysis

• Must have previously untreated (with definitive therapy) prostate cancer with intermediate or high risk features defined as:

• Intermediate risk:

• Prostate-specific antigen, (PSA) level is between 10 and 20 ng/ml or
• Gleason score is 7 or
• Stage T2b or T2c
• High Risk:

• Gleason 8 and higher OR
• PSA greater than 20 at the time of diagnosis OR
• Seminal vesicle involvement OR
• Possible (on magnetic resonance imaging (MRI) Extra-capsular extension (T3 disease)
• Patients must be eligible for and must be planning to undergo radical prostatectomy
• Patients must have testosterone levels greater than or equal to 100 ng/dL
• Men age greater than or equal to 18 years.

• Children are excluded because prostate cancer is not common in pediatric populations.
• Women are not eligible because this disease occurs only in men.
• Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 1
• Patients must have normal organ and marrow function as defined below:
• Hemoglobin greater than or equal to 9 g/dL
• leukocytes greater than or equal to 3,000/mcL
• absolute neutrophil count greater than or equal to 1,500/mcL
• platelets greater than or equal to 150,000/mcL
• total bilirubin within normal institutional limits
• Aspartate aminotransferase (AST)/Serum glutamic-oxaloacetic transaminase(SGOT)/Alanine aminotransferase (ALT) Serum glutamic pyruvic transaminase (SGPT) less than or equal to 3 X institutional upper limit of normal
• creatinine within normal institutional limits

OR

• creatinine clearance greater than or equal to 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal.
• The effects of enzalutamide on the developing human fetus are unknown. For this reason and because androgen receptor antagonists as well as other therapeutic agents used in this trial are known to be teratogenic, male participants and their female partners of child bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence). Male participants should use a condom if having intercourse with a pregnant woman. Additionally, a condom plus another effective method of birth control is recommended during therapy and for 3 months after treatment for male participants having intercourse with a woman of reproductive potential. Should a woman become pregnant or suspect she is pregnant while her partner is participating in this study, she should inform her treating physician immediately.
• Ability of subject to understand and the willingness to sign a written informed consent document.
• Willingness to undergo biopsy.
• Ability to detect lesions within prostate on magnetic resonance imaging (MRI) for biopsy
• Willingness to travel to National Institutes of Health (NIH) for follow-up visits.

Exclusion Criteria

• Patients who are receiving any other investigational agents (in the past 28 days) or herbal medications (within 1 day).
