About this study

Official title: ODM-201 Maintenance Therapy in Patients With Metastatic Castration Resistant Prostate Cancer (mCRPC) Previously Treated With Novel Hormonal Agents and Non-progressive Disease After Subsequent Treatment With a Taxane: A Multicenter Randomized Double-blind Placebo-controlled Phase II Trial.

The main objective of the trial is to assess impact of maintenance therapy with ODM-201 on radiographic progression-free survival (rPFS) of patients with mCRPC pretreated with novel hormonal agents who have non-progressive disease after chemotherapy with a taxane.

Read the detailed description

The treatment of metastatic castration-resistant prostate cancer has evolved rapidly over the past few years. First line treatment with one of the novel antihormonal drugs abiraterone or enzalutamide followed by chemotherapy with docetaxel is now standard of care. If a patient has disease stabilization on chemotherapy he undergoes a watchful waiting period and further treatment is only started at the time of disease progression. This trial tests the immediate use of the novel androgen receptor antagonist ODM-201 as maintenance treatment after chemotherapy aiming at prolonging radiographic progression free survival as compared to watchful waiting.

The main objective of the trial is to assess impact of maintenance therapy with ODM-201 on radiographic progression-free survival (rPFS) of patients with mCRPC pretreated with novel hormonal agents who have non-progressive disease after chemotherapy with a taxane.

What is being measured

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

  1. Radiographic progression-free survival (rPFS) at 12 weeks

    Radiographic progression-free survival is defined as the time from treatment start to radiographic disease progression or death from any cause, whichever occurs earlier.

    Measured: At 12 weeks after treatment start

Secondary outcomes (6)

  1. Radiographic progression-free survival (rPFS)

    Radiographic progression-free survival is defined as the time from treatment start to radiographic disease progression or death from any cause, whichever occurs earlier.

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

  2. Time to PSA progression

    PSA progression is defined as:

    • In case PSA levels had not decreased under treatment with the study drug: ≥ 25% increase over baseline (last PSA measurement before treatment start) AND an increase in the absolute PSA value of ≥ 5 ng/mL.
    • In case of PSA response < 50% under treatment with the study drug: ≥ 25% increase over the nadir AND an increase in the absolute PSA value of ≥ 5 ng/mL.
    • In case of PSA response ≥ 50% under treatment with the study drug: ≥ 50% increase over the nadir AND an increase in the absolute PSA value of ≥ 5 ng/mL

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

  3. Time to symptomatic/clinical progression

    Symptomatic/clinical progression is defined by one of the following:

    • Occurrence of a SRE due to bone metastases, defined as pathologic fracture, spinal cord compression, palliative radiation to bone, or surgery to bone
    • Treating physician decides for intervention due to new disease related complications (e.g., urinary obstruction, hydronephrosis)

    Measured: treatment start to the time point of symptomatic/clinical progression (estimated up to 1 year)

  4. Event-free survival

    Event-free survival is defined as the time from treatment start until the event of interest.

    Measured: treatment start until the event of interest (estimated up to 1 year)

  5. Overall survival

    Overall survival is defined as the time from treatment start until death from any cause.

    Measured: time from trial randomization to the date of death from any cause (estimated up to 6 years)

  6. PSA response (30%, 50%, 90% and best)

    30% PSA response is defined as a decrease in PSA level of at least 30% (compared to baseline PSA).

    50% PSA response is defined as a decrease in PSA level of at least 50% (compared to baseline PSA).

    90% PSA response is defined as a decrease in PSA level of at least 90% (compared to baseline PSA).

    Best PSA response is defined as the percentage of change in PSA from baseline to the maximum decline in PSA at any point under treatment. If there is a steady increase after baseline, the best response is defined as the percentage of change in PSA from baseline to the minimum increase in PSA at any point under treatment. Baseline is defined as the latest recorded measurement prior to the first dose of trial treatment.

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

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ODM-201 in people with Prostate Cancer Metastatic and Prostate Cancer, run by Swiss Cancer Institute at 32 sites in 4 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 22 inclusion and 14 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: stopped early, as of the sponsor's last update on 13 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 32 sites in Spain, Switzerland, Italy, France. 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. Some participants in this study may receive a placebo. 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?

The study was stopped early (reason given: Decision Board no further financial support after 3 years of follow-up as remaining patients in follow-up phase would not relevantly change the endpoints.). Results are not available in the source record.

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?

Radiographic progression-free survival (rPFS) at 12 weeks (time frame: At 12 weeks after treatment start). 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 NCT02933801, 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 13 Mar 2024; AzTrials last refreshed its copy on 7 Nov 2026.
