About this study

Official title: A Phase 2, Randomized, 3-arm Study of Abiraterone Acetate Alone, Abiraterone Acetate Plus Degarelix, a GnRH Antagonist, and Degarelix Alone for Patients With Prostate Cancer With a Rising PSA or a Rising PSA and Nodal Disease Following Definitive Radical Prostatectomy

In April 2011, the United States Food and Drug Administration (FDA) approved the oral drug abiraterone acetate (Zytiga ®) in combination with prednisone (a steroid) to treat patients with metastatic castration-resistant prostate cancer who have received prior docetaxel (chemotherapy). In December 2012, the FDA approved Zytiga ® in combination with prednisone to treat patients with metastatic castration-resistant prostate cancer who have not received prior chemotherapy. Degarelix (Firmagon ®), a testosterone lowering agent given as a monthly injection, is FDA approved for the treatment of patients with advanced prostate cancer. The purpose of this study is to evaluate abiraterone acetate and prednisone in combination with degarelix as a possible treatment for PSA recurrent prostate cancer as compared to abiraterone acetate alone and degarelix alone. This will be the first time these drugs will be used together.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Abiraterone acetateDrug

    Patients randomized to abiraterone acetate and prednisone (Group 1) will be instructed to take 1000 mg (four 250 mg tablets) of abiraterone acetate orally (PO) at least 1 hour before a meal and 2 hours after a meal every day. These patients will also be treated with prednisone 5 mg once daily with food.

  • Abiraterone acetate plus degarelixDrug

    Patients randomized to abiraterone acetate plus degarelix and prednisone (Group 2) will be instructed to take 1000 mg (four 250 mg tablets) of abiraterone acetate orally (PO) at least 1 hour before a meal and 2 hours after a meal every day and prednisone 5 mg once daily with food. Patients will also be given two subcutaneous injections of degarelix 120 mg on Cycle 1, Day 1(starting dose) and 80 mg subcutaneous doses (maintenance doses) every 28 days (±3 days) thereafter.

  • DegarelixDrug

    Patients randomized to degarelix alone (Group 3) will be given two subcutaneous injections of degarelix 120 mg on Cycle 1, Day 1 (starting dose) and 80 mg subcutaneous doses (maintenance doses) every 28 days (± 3 days) thereafter.

What is being measured

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

  1. Progression-free Survival (PFS)

    defined as an undetectable PSA (using a routine non-ultrasensitive PSA assay) with non-castrate level of testosterone (>150 ng/dL) at 18 months from the time of treatment initiation (PSA0).

    Measured: 18 months

  2. Soft Tissue Complete Response

    In addition to an undetectable PSA, any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm (Complete Response per RECIST) in order to meet the criteria for PFS. Outcome in subjects who develop radiographically evident metastatic disease while on study will be considered treatment failures independent of their respective PSA values.

    Measured: 1 year

Secondary outcomes (5)
  1. PSA Response Rate

    The percentage of patients with a non-castrate level of testosterone (>150 ng/dL) and an undetectable PSA at 8 months from PSA0 will be measured.

    Measured: 8 months

  2. Overall Quality of Life

    with particular attention to libido, potency, anxiety, depression, hot flashes, and fatigue. Effects of each arm on health-related quality of life will be assessed via PRO Survey (Appendix C) completed on paper by the patient at the following study visits: Up to 30 Days Prior to Randomization, each Day 1 of Treatment Cycle, End of Treatment, and each Post-Treatment Follow-up.Effects of each arm on quality of life,

    Measured: 1 year

  3. Non-hematologic Adverse Events

    Safety will be evaluated according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Safety assessments will be based on medical review of adverse event reports and the results of vital sign measurements, physical examinations and clinical laboratory tests throughout the conduct of the study.

    Measured: 1 year

  4. Testosterone and Luteinizing Hormone (LH) Recovery Rates

    Testosterone and LH recovery rates will be measured at 8 months from the start of randomization and at each month of the 10 month follow up period.

    Measured: 8 -10 months

  5. Correlative Tissue Analysis

    Tissue samples will be utilized for morphologic assessment, percent tumor involvement (if applicable), and immunohistochemistry. The immunohistochemical markers assessed may be AR, PTEN, PSMA, fatty acid synthase (FASN), phospho-AMPK, phospho-ACC, phospho-S6 kinase, phospho-Akt for the assessment of the AMPK, lipid synthesis, mTOR pathways, and immunological markers.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Abiraterone acetate, Abiraterone acetate plus degarelix and Degarelix in people with Prostate Cancer, run by Memorial Sloan Kettering Cancer Center at 16 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 27 inclusion and 22 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 19 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 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 19 Nov 2021). 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?

Progression-free Survival (PFS) (time frame: 18 months). 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?
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 19 Nov 2021.
