Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Histologically confirmed prostate adenocarcinoma with metastasis either starting or recently started on LHRH analogue therapy. [Late induction permitted within 3 months of starting LHRH analogue therapy or antiandrogen]
  • All patients who have not initiated hormone therapy (Early induction patients) must have elevated PSA ≥ 4 ng/ml within 28 days prior to registration. For late induction registrations, PSA must be ≥ 4 ng/ml prior to start of androgen deprivation therapy; either antiandrogen or LHRH analogue or GNRH antagonist .If patients are on antiandrogen, this will need to be discontinued for at least 7 days prior to registration.
  • Patients with a history of prior neoadjuvant or adjuvant hormone therapy are eligible provided they have received twenty four or less months of hormone treatment (single or combination treatment, excluding orchiectomy). Both therapies (neoadjuvant/adjuvant hormone therapy) must have been discontinued at least 6 months prior to registration. This is intended to exclude patients who might have been rendered indirectly androgen insensitive.
  • There must be no plans to receive concomitant chemotherapy, biological response modifiers, radiation therapy or hormonal therapy. Concomitant radiation therapy is allowed for the palliation of severe pain/neuropathic compression. Prior or concomitant use of megestrol acetate for the treatment of hot flashes is allowed.
  • Patients must have a performance status of 0 - 2 by Zubrod Criteria.
  • Patients must have recovered from any major infections and/or surgical procedures and,in the opinion of the investigator, not have significant active medical illness precluding protocol treatment or survival.

  • For all patients a bone scan must be performed within 60 days prior to registration for tumor assessment. CT scans (abdomen and pelvis) and chest x-ray are optional, but must be repeated if used for disease assessment.

About this study

Official title: Randomized Phase II Screening Trial of Enzalutamide/MDV-3100 and LHRH Analogue vs Combined Androgen Deprivation (LHRH Analogue + Bicalutamide) in Metastatic Hormone Sensitive Prostate Cancer

This randomized phase II trial studies if enzalutamide added to standard luteinizing hormone-releasing hormone (LHRH) analogue therapy will improve effects against prostate cancer compared to the standard therapy of LHRH analogue and bicalutamide. Hormone therapies stop the body from producing or block the effect of male sex hormones (testosterone). Enzalutamide blocks the effect of male sex hormones which are responsible for the growth of prostate cancer. Hormonal therapies that lower the level of testosterone are among the most effective treatments for prostate cancer that have spread to other areas of the body (metastasized). It is not yet known whether LHRH analogue therapy with bicalutamide is more effective than LHRH analogue therapy with enzalutamide in treating prostate cancer.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To compare the rates of achieving prostate-specific antigen (PSA) remission at month 7 with LHRH analogue therapy and enzalutamide (Arm A) with that achieved with LHRH analogue and bicalutamide (Arm B) in metastatic hormone sensitive prostate cancer.

SECONDARY OBJECTIVES:

  1. To compare the primary endpoint by race. II. To compare the rates of each of 2 types of response by treatment arm: measurable disease response; and PSA response.

III. To compare each of 7 time-to-event endpoints by treatment arm: duration of overall response (RD); duration of stable disease (SDD); time to treatment failure (TTF); time-to-progression (TTP); TTP in patients with bone metastases; progression-free survival (PFS); and overall survival (OS).

IV. To compare the rates of each type of toxicity by treatment arm. V. To compare the incidence rate of skeletal related events (SRE), and the time until SRE, separately by treatment arm.

VI. To compare the rates of circulating tumor cell (CTC) response by treatment arm.

VIII. To explore the molecular mechanisms within the androgen receptor pathway by determining the levels of chemokine (C-X-C motif) receptor 4 (CXCR4) and transmembrane protease, serine 2 (TMPRSS2)-v-ets avian erythroblastosis virus E26 oncogene homolog (ERG) expression, androgen metabolism enzymes; androgen receptor variants, and length of cytosine-adenine-guanine (CAG) repeats within the androgen receptor gene, and to associate them with the primary endpoint.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive enzalutamide orally (PO) once daily (QD) and undergo orchiectomy or receive LHRH analogue therapy (leuprolide acetate, goserelin acetate, or any other Food and Drug Administration [FDA] approved preparation). Treatment continues in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive bicalutamide PO QD and undergo orchiectomy or receive LHRH analogue therapy as in Arm A. Treatment continues in the absence of disease progression or unacceptable toxicity.

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

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing enzalutamide, bicalutamide and orchiectomy in people with Adenocarcinoma of the Prostate and Recurrent Prostate Cancer, run by Barbara Ann Karmanos Cancer Institute at 4 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 14 inclusion and 19 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 10 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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 10 May 2023). 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?

Number of Participants With PSA Remission Assessed Using the Prostate Cancer Clinical Trials Working Group (PCWG2) Criteria (time frame: Month 7). 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 NCT02058706, 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 10 May 2023; AzTrials last refreshed its copy on 8 Nov 2026.
