About this study

Official title: Orteronel Maintenance Therapy in Patients With Metastatic Castration Resistant Prostate Cancer (mCRPC) Previously Treated With Novel Hormonal Agents and Non-progressive Disease After Treatment With a Taxane: A Multicentre Randomized Double-blind Placebo-controlled Phase III Trial

The main object of this multicenter, randomized, double-blind, placebo-controlled phase III trial is to assess impact of maintenance of orteronel on disease progression and hence on quality of life of patients with metastatic castration resistant prostate cancer pretreated with novel hormonal agents who have non-progressive disease after chemotherapy with a taxane.

Read the detailed description

Background

One in six men will be diagnosed with cancer of the prostate during his lifetime. Accordingly, prostate cancer is the most common cancer amongst men in the western world. In Switzerland approx. 5'400 men are diagnosed with the disease and 1'300 die of prostate cancer every year. Prostate cancer represents 30% of all cancer diagnoses in men. Despite earlier detection and new treatments the life time risk to die of prostate cancer has remained stable at 3% since 1980.

In metastatic castration-resistant prostate cancer (with progression on antihormonal therapy) the primary standard therapy for a long time consisted of chemotherapy with docetaxel. It was recently shown that treatment with the novel androgen synthesis blocker, abiraterone (Zytiga) before chemotherapy can prolong survival. Abiraterone belongs to a group of agents that very effectively inhibits the androgen synthesis via blockade of the key enzyme cytochrome P-450c17 (CYP17).Similar results have been reported for the new androgen antagonist enzalutamide (Xtandi). Today, therefore, many patients with metastatic castration-resistant prostate cancer (mCRPC) first receive therapy with abiraterone or enzalutamide. After this, chemotherapy with docetaxel (Taxotere) or cabazitaxel (Jevtana) is usually administered if there is any further progression of the disease. After the end of chemotherapy, the patient is regularly checked and, in the event of disease progression, further treatments may be given. These could consist of renewed hormonal therapy or chemotherapy with cabazitaxel. Besides abiraterone, the medicine orteronel also acts by blocking testosterone production via the key enzyme CYP17. By selectively inhibiting the extragonadal synthesis of androgens in either the adrenal cortex or in prostate tumor cells, orteronel, a selective non-steroidal CYP17 inhibitor, may represent a new therapeutic option for patients with CRPC. Initial results have shown that orteronel effectively inhibits testosterone synthesis.

Hypothesis and aim of the study

Since various new options are available for treatment of castration-resistant prostate cancer at present, this raises the question as to the order in which these treatments should best be given. Initial results show that cross-resistance could develop between the new kinds of hormone therapy abiraterone and enzalutamide. There is evidence to suggest that any resistance to hormone treatments could be reversible as a result of prior treatment with chemotherapy. This study is designed to investigate this approach. It is also intended to investigate whether early use of the well-tolerated testosterone synthesis blocker orteronel in patients with mCRPC leads to an increase in the time to the progression of disease. Trials examining other advanced malignant diseases such as lung cancer have shown that initiating an effective treatment earlier in the disease course at the end of a first-line chemotherapy (so called switch maintenance therapy) is beneficial in terms of progression free survival (PFS) but also overall survival (OS). This may also hold true for early administration of antihormonal agents in patients with mCRPC.

Patients who have already received a novel hormonal therapy followed by chemotherapy with a taxane and have experienced a stabilization of disease on this regimen are included in the study. It is also intended to test whether this treatment has a positive influence on the quality of life of patients.

The aim of this trial is to test the hypothesis that using orteronel treatment immediately after cessation of chemotherapy with a taxane can prolong event-free survival (EFS), consequently maintains a good quality of life (QL) and could eventually also improve overall survival for the group of patients pretreated with novel hormonal agents.

What is being measured

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

  1. Event-free survival

    The primary endpoint of the trial is EFS. An event is defined as ONE of the following:

    • death from any cause
    • the presence of radiographic progression AND symptomatic/clinical progression
    • the presence of radiographic progression AND PSA progression
    • the presence of symptomatic/clinical progression AND PSA progression

    Measured: 5 months

Secondary outcomes (7)
  1. Adverse events (AEs)

    All AEs will be assessed according to NCI CTCAE v4.0.

    Measured: Throughout treatment phase (estimated up to 1 year) until 30 days after last drug administration or prior to start of subsequent anticancer treatment (whichever occurs first)

  2. Prostate-specific antigen (PSA) response (30%, 50%, 90% and best)

    Measured: PSA level at baseline and every 4 weeks until disease progression (estimated up to 1 year)

  3. Time to PSA progression

    Measured: PSA level at baseline and every 4 weeks until disease progression (estimated up to 1 year)

  4. Radiographic progression-free survival (rPFS)

    Measured: Every 12 weeks until disease progression (estimated up to 1 year)

  5. Overall survival (OS)

    Measured: time from trial randomization to the date of death from any cause (estimated up to 4 years)

  6. Quality of Life (QL)

    Measured: First 6 months of trial treatment

  7. Pain Response

    Measured: First 6 months of trial treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Orteronel in people with Prostate Cancer, run by Swiss Cancer Institute at 7 sites in Switzerland.

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 25 inclusion and 21 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: withdrawn, as of the sponsor's last update on 30 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Switzerland. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Event-free survival (time frame: 5 months). 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 30 Jul 2018.
