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

  • Has histologically or cytologically confirmed diagnosis of adenocarcinoma of the prostate.
  • Is a candidate for, in the opinion of the investigator, at least 1 year of continuous androgen deprivation therapy for the management of androgen-sensitive advanced prostate cancer with 1 of the following clinical disease state presentations:
  • Evidence of biochemical (PSA) or clinical relapse following local primary intervention with curative intent, such as surgery, radiation therapy, cryotherapy, or high-frequency ultrasound and not a candidate for salvage treatment by surgery; or
  • Newly diagnosed androgen-sensitive metastatic disease; or
  • Advanced localized disease unlikely to be cured by local primary intervention with either surgery or radiation with curative intent.
  • Has a serum testosterone at the Screening visit of ≥ 150 ng/dL (5.2 nanomoles [nmol]/liter [L]).
  • Has a serum PSA concentration at the Screening visit of > 2.0 ng/milliliter (mL) (2.0 microgram [μg]/L), or, when applicable, post radical prostatectomy of > 0.2 ng/mL (0.2 μg/L) or post radiotherapy, cryotherapy, or high frequency ultrasound > 2.0 ng/mL (2.0 μg/L) above the post interventional nadir.
  • Has an Eastern Cooperative Oncology Group performance status of 0 or 1 at initial screening and at baseline.

Who cannot join

  • In the investigator's opinion, is likely to require chemotherapy or surgical therapy for symptomatic disease management within 2 months of initiating androgen deprivation therapy.
  • Previously received gonadotropin-releasing hormone analog or other form of androgen deprivation therapy (estrogen or antiandrogen) for > 18 months total duration. If androgen deprivation therapy was received for ≤ 18 months total duration, then that therapy must have been completed at least 3 months prior to baseline. If the dosing interval of the depot is longer than 3 months, then the prior androgen deprivation therapy must have been completed at least as long as the dosing interval of the depot.

About this study

Official title: HERO: A Multinational Phase 3 Randomized, Open-label, Parallel Group Study to Evaluate the Safety and Efficacy of Relugolix in Men With Advanced Prostate Cancer

The purpose of this study is to determine the efficacy and safety of relugolix 120 milligrams (mg) orally once daily for 48 weeks on maintaining serum testosterone suppression to castrate levels (< 50 nanograms/deciliter [ng/dL]) in participants with androgen-sensitive advanced prostate cancer.

Read the detailed description

This is a phase 3, multinational, randomized, open-label, parallel group study to evaluate the efficacy and safety of oral daily relugolix 120 mg in participants with androgen-sensitive advanced prostate cancer who require at least 1 year of continuous androgen-deprivation therapy. Relugolix 120 mg orally once daily or leuprolide acetate depot suspension, 22.5 mg (or 11.25 mg in Japan and Taiwan based on local labels), every 3 months by subcutaneous injection will be administered to participants.

There are 2 analyses for this study, a primary analysis and a final analysis.

Primary Analysis:

The primary analysis of efficacy and safety has been completed (N=934). Participants were randomized 2:1 to receive relugolix or leuprolide for 48 weeks, followed by a 30-day safety follow-up visit or early termination 30-day safety follow-up.

Final Analysis:

The final analysis will occur after additional participants with metastatic disease (approximately 130) have been enrolled and randomized from any sites to the study, and have completed the 48-week treatment period. A cohort of participants enrolled in China and Taiwan will be analyzed separately once they have completed treatment to support registration in China.

Eligible participants were randomized 2:1 to relugolix or leuprolide arm and will attend visits monthly (every 4 weeks) where serum testosterone and prostate-specific antigen will be assessed. Safety will be assessed throughout the study by monitoring adverse events, vital signs, physical examinations, clinical laboratory tests, and 12-lead electrocardiograms.

Castration resistance-free survival will be assessed up to Week 49, Day 1 of the study and reported as part of the final analysis.

The study enrolled 1134 participants, including 139 participants with metastatic advanced prostate cancer to support the analysis of the secondary endpoint of castration resistance-free survival and 93 Chinese participants (enrolled in China and Taiwan) to support registration in China.

  23. Maximum Observed Plasma Concentration (Cmax) Of Relugolix

    The Cmax of relugolix was determined for single and repeat doses in subsets of participants from Japan. Single dose pharmacokinetics (PK) was assessed on Day 1 following an initial 360 mg dose of relugolix. Repeat dose PK was assessed following repeat dosing of relugolix 120 mg once daily for 2 weeks.

    Measured: Predose and 0.5, 1, 2, 4, 6, 8, 12, and 24 hours postdose on Day 1 and Week 2

  24. Area Under The Concentration-Time Curve (AUC0-τ) Of Relugolix

    The AUC0-τ of relugolix was determined for single and repeat doses in subsets of participants from Japan. Single dose PK was assessed on Day 1 following an initial 360 mg dose of relugolix. Repeat dose PK was assessed following repeat dosing of relugolix 120 mg once daily for 2 weeks.

    Measured: Predose and 0.5, 1, 2, 4, 6, 8, 12, and 24 hours postdose on Day 1 and Week 2

  25. Time To Maximum Observed Plasma Concentration (Tmax) Of Relugolix

    The Tmax of relugolix was determined for single and repeat doses in subsets of participants from Japan. Single dose PK was assessed on Day 1 following an initial 360 mg dose of relugolix. Repeat dose PK was assessed following repeat dosing of relugolix 120 mg once daily for 2 weeks.

    Measured: Predose and 0.5, 1, 2, 4, 6, 8, 12, and 24 hours postdose on Day 1 and Week 2

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Relugolix and Leuprolide Acetate in people with Prostate Cancer, run by Myovant Sciences GmbH at 162 sites in 22 countries.

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 8 inclusion and 7 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 18 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 162 sites in United States, Japan, China, Brazil, Slovakia and 17 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 25 Mar 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?

Sustained Castration Rate (time frame: From Week 5 Day 1 (Day 29) to Week 49 Day 1 (Day 337)). 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 NCT03085095, which also lists 3 linked publications.

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 18 Jan 2022.
