What is being measured

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

  1. Number of participants with Adverse Events (AEs)

    Changes from baseline measurements considered clinically significant by the Investigator will be reported as AEs.

    Measured: 28 days

  2. Change from baseline in hormone levels

    The serum concentrations of Follicle Stimulating Hormone (FSH), Luteinising Hormone (LH), Estradiol (E2), total testosterone and free testosterone levels (actual values as well as percentage change from pre-dose concentration) will be listed and summarized descriptively by treatment group.

    Measured: 28 days

Secondary outcomes (9)
  1. Change from baseline in haemostasis parameters

    The relative change in Activated Protein C (APC)-resistance, prothrombin factor 1 + 2, D-dimer, free Tissue Factor Pathway Inhibitor (TFPI), antothrombin activity, protein S activity and angiotensinogen levels and the actual change from baseline will be calculated by treatment group.

    Measured: 28 days

  2. Change from baseline in lipid parameters

    The relative change in total cholesterol, triglycerides, High Density Lipoprotein (HDL) cholesterol, Low Density Lipoprotein (LDL) cholesterol, Lipoprotein A (Lp(A)) levels and the actual change from baseline will be calculated by treatment group.

    Measured: 28 days

  3. Change from baseline in glucose levels

    The relative change in glucose levels and the actual change from baseline will be calculated by treatment group.

    Measured: 28 days

  4. Change from baseline in bone turnover markers

    The relative change in osteocalcin, type I collagen telopeptide (CTX-1) and parathyroid hormone (PTH) and the actual change from baseline will be calculated by treatment group.

    Measured: 28 days

  5. Change from baseline in sex-hormone binding globulin (SHBG) levels

    The relative change in SHBG levels and the actual change from baseline will be calculated by treatment group.

    Measured: 28 days

  6. Pharmacokinetic effect of estetrol

    Area under the plasma concentration versus time curve (AUC)

    Measured: 28 days

  7. Pharmacokinetic effect of estetrol

    Terminal elimination half-life (t1/2)

    Measured: 28 days

  8. Pharmacokinetic effect of estetrol

    Time to reach Cmax (tmax)

    Measured: 28 days

  9. Pharmacokinetic effect of estetrol

    Peak plasma concentration (Cmax)

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing estetrol in people with Prostatic Neoplasms, run by Pantarhei Oncology B.V. at 1 site in Netherlands.

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 23 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 9 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 Adverse Events (AEs) (time frame: 28 days). The study lists 2 primary outcomes in all. 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 NCT02718378, 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 9 Feb 2017.
