About this study

Official title: Phase II Trial of Radiation With Androgen Deprivation: Abiraterone Acetate, Prednisone and Luteinizing Hormone Releasing Hormone Agonist Prior to Radiation Therapy

This phase II trial studies the side effects and how well abiraterone acetate, prednisone, and leuprolide acetate or goserelin before and during radiation therapy works in treating patients with localized or locally advanced prostate cancer. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as abiraterone acetate, leuprolide acetate, and goserelin, may lessen the amount of androgens made by the body. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving abiraterone acetate and leuprolide acetate or goserelin before or together with radiation therapy may be an effective treatment for prostate cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate the safety of abiraterone (abiraterone acetate) and prednisone with luteinizing hormone-releasing hormone agonist given as neoadjuvant and concurrent therapy with external beam radiation in patients with localized prostate cancer.

II. To determine whether pharmacologic suppression of the prostatic androgen axis by inhibition of androgen production with abiraterone can decrease tissue androgen levels to below those observed with gonadotropin-releasing hormone (GnRH) agonist suppression of testicular androgens.

SECONDARY OBJECTIVES:

  1. To determine whether treatment with abiraterone acetate with luteinizing releasing hormone agonist will be more effective than agonist with bicalutamide in inducing inhibition of androgen-regulated gene expression and increased apoptotic cell death as assessed by immunohistochemistry, complementary deoxyribonucleic acid (cDNA) microarray analysis and reverse transcription-polymerase chain reaction (RT-PCR).

II. To evaluate time to prostate-specific antigen progression in patients treated with GnRH agonist with abiraterone acetate.

OUTLINE:

Patients receive abiraterone acetate orally and prednisone once daily for 24 weeks. Patients also receive leuprolide acetate or goserelin in weeks 1 and 13. Patients undergo external beam radiotherapy starting in week 15 for 8.5 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 5 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of Acute and Chronic Grade 3 or Greater Toxicity as Evaluated Using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 3.0

    Incidence of acute and chronic grade 3 or greater toxicity as evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.0he distribution of time to late adverse events (observed severities of adverse events over time) will be estimated using the Kaplan-Meier method.

    Measured: Up to 24 months after initiation of radiation therapy

  2. Levels of Dihydrotestosterone (DHT) and Testosterone in Prostate Biopsy Sample Assessed by Mass Spectrometry

    The levels from patients treated in this study will be compared to a control set of biopsies acquired from a separate but similar population of men with intermediate and high risk prostate cancer treated with three months of combined Luteinizing hormone releasing hormone agonist and bicalutamide as part of standard of care.

    Measured: Week 12

Secondary outcomes (1)

  1. Median Time to Prostate Specific Antigen Progression

    Defined as the date of an increase of 2ng/mL or more above the Prostate specific antigen nadir achieved after completion of radiation with the date of progression defined as the date on which that value was measured. Distribution of time-to-event variables will be estimated using the Kaplan-Meier product-limit method. Estimated with two-sided 95% confidence intervals.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing abiraterone acetate, prednisone and leuprolide acetate in people with Adenocarcinoma of the Prostate and Stage II Prostate Cancer, run by University of Washington at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 20 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Jun 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Acute and Chronic Grade 3 or Greater Toxicity as Evaluated Using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 3.0 (time frame: Up to 24 months after initiation of radiation therapy). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01023061, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jun 2017.
