Clinical Trial Summary

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.

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 prostate specific androgen (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.

Exclusion Criteria:

• No prior abiraterone or docetaxel therapy for metastatic hormone sensitive prostate cancer. Prior therapy with ADT or first generation anti-androgen receptor therapy (example: bicalutamide) is allowed.

• Completed any hormone therapy for localized prostate cancer and have recovery of testosterone (i.e. testosterone level is >50ng/dL).

• Patients have a histologic diagnosis of small cell prostate cancer or pure squamous cell prostate cancer.

• Known brain metastases or cranial epidural disease unless adequately treated with radiotherapy and/or surgery (including radiosurgery) and stable for at least 4 weeks before first dose of study treatment. Eligible subjects must be neurologically asymptomatic and without corticosteroid treatment at the time of first dose of study treatment.

• The subject has uncontrolled, significant intercurrent or recent illness including, but not limited to, the following conditions:

• Cardiovascular disorders:

• Congestive heart failure New York Heart Association class 3 or 4, unstable angina pectoris, serious cardiac arrhythmias within 3 months of study enrollment.

• Uncontrolled hypertension defined as sustained blood pressure (BP) > 170 mm Hg systolic or > 100 mm Hg diastolic despite optimal antihypertensive treatment.

• Stroke (including transient ischemic attack (TIA)), myocardial infarction (MI), or other ischemic event, or arterial thromboembolic event within 3 months before first dose.

• Other clinically significant disorders that would preclude safe study participation. As defined by the treating physician.

• Known history of testing positive for human immunodeficiency virus (HIV) and cluster of differentiation 4 (CD4) count is below 200 or known acquired immunodeficiency syndrome diagnosis.

• Known history of hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or detectable HCV ribonucleic acid [RNA] if anti-HCV antibody screening test positive) and a detectable viral count at screening.

• Use of live virus vaccine within 4 weeks of the first dose of treatment or planned use while on trial for the duration of potential docetaxel treatment. Live vaccine use is acceptable after chemotherapy or for patients randomized to the abiraterone arm. There are no restrictions on inactive viruses.

• Known prior severe hypersensitivity to investigational product or any component in its formulations (National Cancer Institute [NCI] CTCAE v5.0 grade >= 3).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Quality of Life - FACT-P	The impact of abiraterone acetate and docetaxel on health related quality of life will be assessed every 3 months from screening to month 12 of treatment or follow-up. The scale used will be the Functional Assessment of Cancer Therapy-Prostate (FACT-P) scale. The total score ranges from 0 to 156, with higher scores indicating a higher quality of life. The primary endpoint was intended to be quality of life at 12 months, but since no participants completed 12 months of treatment/follow-up, scores at baseline and 3 months are reported instead.	Planned for up to one year, but actual was 3 months
Secondary	Prostate-specific Antigen (PSA) Response	PSA evaluations will occur every 3 months while on study. PSA response is defined as a reduction in PSA value of greater than or equal to 90% from baseline, reported as a count of participants who had a PSA response on the study.	Planned for up to 18 months, but actual was 3 months
Secondary	Change in Quality of Life - FACT/GOG-NTX	Quality of Life questionnaires will be done every 3 months while participants are on treatment. The scale used will be the Functional Assessment of Cancer Therapy (FACT)/Gynecologic Oncology Group (GOG)-Neurotoxicity (NTX) (FACT/GOG-NTX) scale (version 4). FACT/GOG-NTX total score ranges from 0 to 152, with higher scores indicating a higher quality of life.	Planned for up to 18 months, but actual was 3 months
Secondary	Change in Quality of Life - PROMIS Fatigue	Quality of Life questionnaires will be done every 3 months while participants are on treatment. The scale used will be the Patient-Reported Outcomes Measurement Information System (PROMIS) Fatigue scale. Total raw scores range from 7 to 35, with higher scores indicating a higher level of fatigue.	Planned for up to 18 months, but actual was 3 months
Secondary	Prostate Specific Antigen Progression Free Survival (PSA-PFS)	Prostate Specific Antigen (PSA) will be measured every three months while on study. PSA Progression Free Survival (PSA-PSF) will be reported as the number of participants who have not demonstrated PSA progression by the end of the follow-up period. PSA progression is defined by meeting the following criteria: 1) an increase in PSA of greater than or equal to 25% from baseline or nadir, AND 2) an increase in PSA of at least 2 ng/dL, AND 3) the increase is confirmed at least 3 weeks later. This analysis was planned for up to 18 months following study enrollment, but the only participant enrolled on the study was only followed for 3 months.	Planned up to 18 months, but actual was 3 months
