Docetaxel or Abiraterone Acetate With ADT in Treating Patients With Metastatic Hormone Sensitive Prostate Cancer

NCT03827473

Description:

This phase II trial studies how well docetaxel or abiraterone acetate work when combined with androgen deprivation therapy (ADT) in treating patients with hormone sensitive prostate cancer that has spread to other parts of the body. Drugs used in chemotherapy, such as docetaxel and abiraterone acetate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Antihormone therapy, such as ADT may lessen the amount of androgen made by the body. It is not yet known whether docetaxel or abiraterone acetate work better when combined with ADT in treating patients with hormone sensitive prostate cancer.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To assess the impact of abiraterone acetate (abiraterone) and docetaxel on total quality
      of life between screening and month 12 of the study.

      SECONDARY OBJECTIVES:

      I. To assess PSA response rates across the entire population and compared between groups.

      II. To assess impact of abiraterone and docetaxel on additional quality of life measurements
      and quality of life trends throughout the duration of the study.

      III. To assess the potential clinical efficacy between treatment groups.
