NCT02058706

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With PSA Remission Assessed Using the Prostate Cancer Clinical Trials Working Group (PCWG2) Criteria

    Number of Participants with PSA Remission Assessed Using the Prostate Cancer Clinical Trials Working Group (PCWG2) Criteria specifically at the 7 month time point. The binary endpoint (yes/no) will be summarized with its point estimate (an occurrence rate), and 2-sided Wilson type 95% confidence interval (CI). PSA response rates will be compared by treatment arm in a stratified logistic regression model.

    Month 7

Secondary Outcomes (9)

  • Achievement of Measurable Disease Response

    Up to 2 years

  • Achievement of PSA Response Assessed Using PCWG2 Criteria

    Up to 2 years

  • The Percentage of Patients Responding

    6 months

  • Time to Treatment Failure

    Assessed up to 6 years.

  • Percentage of Patients Progression Free at One Year

    assessed at 1 year

  • +4 more secondary outcomes

Study Arms (2)

Arm A (enzalutamide and LHRH analogue therapy)

EXPERIMENTAL

Patients receive enzalutamide orally PO QD and undergo orchiectomy or receive LHRH analogue therapy (leuprolide acetate, goserelin acetate, or any other FDA approved preparation). Treatment continues in the absence of disease progression or unacceptable toxicity.

Arm B (bicalutamide and LHRH analogue therapy)

ACTIVE COMPARATOR

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.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
  • No prior malignancy is allowed except for adequately treated basal cell (or squamous cell) skin cancer, superficial or in situ cancer of the bladder. For an invasive cancer the patients should be disease free for at least 3 years prior to enrollment on study.
  • 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. For late induction registrations, tumor assessment imaging showing metastatic disease must be available prior to start of androgen deprivation therapy.
  • Age 18 or older and willing and able to provide informed consent.
  • Willingness to swallow pills and no medical condition that would interfere with this.
  • Male patient and his female partner who is of childbearing potential must use 2 acceptable methods of birth control (one of which must include a condom as a barrier method of contraception) starting at screening and continuing throughout the study period and for 3 months after final study drug administration. Patients are also required to use a condom if having sex with a pregnant woman.
  • Patient should agree to a tumor tissue biopsy prior to protocol enrollment. Post therapy biopsy is optional.
  • Patients who are being treated with a GNRH antagonist should be willing to switch to a LHRH analogue after registration.
  • Patients must have one of the following a) Low volume disease (defined as no visceral metastases and \< 4 bone metastases) or b) are not candidates for docetaxel based chemotherapy or 3) refused docetaxel chemotherapy

You may not qualify if:

  • History of seizure or any condition that may predispose to seizure (e.g., prior cortical stroke, significant brain trauma) at any time in the past. Also, history of loss of consciousness or transient ischemic attack within 12 months of Day 1 visit;
