Purpose

The purpose of this research study is to find out what effects (good and bad) omeprazole and cabazitaxel, or omeprazole and docetaxel, has on participants and their condition. Investigators believe omeprazole may help the other medications work.

Inclusion Criteria

Exclusion Criteria

  • Patients may not be receiving any other investigational agents. - History of allergic reactions attributed to compounds of similar chemical or biologic composition to omeprazole or taxane therapy. - Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

Experimental
Omeprazole Plus Standard of Care for Prostate Cancer Regimen
This intervention will be given on an outpatient basis. Omeprazole, 80 mg twice daily.
  • Drug: Omeprazole 80 mg twice daily
    Participants will be treated with omeprazole 80 mg twice daily on Day 0. Within 10 days of starting omeprazole, participants will be treated with standard prostate cancer dosing of every three week docetaxel or cabazitaxel based on package insert. Participants that have only had docetaxel will be retreated with docetaxel along with concurrent omeprazole. Patients that have had both docetaxel and cabazitaxel will be retreated with either cabazitaxel or docetaxel (investigators choice) along with concurrent omeprazole. However investigators encourage investigator to choose cabazitaxel in patients previously treated with cabazitaxel.

Detailed Description

Primary Objective(s): Obtain RECIST Overall Response Rate (ORR) of 29% by adding the fatty acid synthase inhibitor, omeprazole to cabazitaxel. ORR defined by partial response (PR) or complete response (CR) in tumor size and bone metastasis Secondary Objectives (only at patients treated at Wake Forest Baptist Comprehensive Cancer Center main campus): - Obtain a prostate specific antigen response rate by adding the fatty acid synthase inhibitor omeprazole to cabazitaxel regimen - Measure pain using the Patient-Reported Outcomes Measurement Information System (PROMIS) at Baseline, Cycle 5, Cycle 12, and every cycle thereafter.
