What is being measured

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

  1. Cmax of Proellex

    Maximum observed concentration of Proellex

    Measured: Up to 72 hours post-dose

  2. AUC0-last of Proellex

    Area under the plasma concentration curve from time 0 to the last measurable plasma concentration time point, up to 72 hours.

    Measured: Up to 72 hours post dose

  3. Tmax of Proellex

    Time to maximum plasma occurrence of Cmax

    Measured: Up to 72 hours post dose

  4. AUC0-infinity of Proellex

    Area under the plasma concentration curve from time 0 to extrapolated to infinity, calculated by summing the area under the curve from time zero to the time of the last quantifiable concentration

    Measured: Up to 72 hours post dose

  5. Terminal Elimination Half-life (T1/2) of Proellex

    Time to maximum plasma occurrence of T1/2, calculated as ln(2)/Elimination rate constant.

    Measured: Up to 72 hours post dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Proellex in people with Pharmacokinetics, run by Repros Therapeutics Inc. at 1 site in United States.

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 6 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 29 Apr 2019. 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 United States. 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 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?

Yes. Results are posted in the registry (first posted 29 Apr 2019). 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?

Cmax of Proellex (time frame: Up to 72 hours post-dose). The study lists 5 primary outcomes in all. 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 29 Apr 2019.
