  4. Plasma PK of Total Radioactivity after Oral Dosing: Time from Dosing to Cmax (tmax)

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  5. Plasma PK of Total Radioactivity after Oral Dosing: Area Under the Plasma Concentration-time Curve from Zero Time to Time of the Last Measurable Concentration (AUC0-last)

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  6. Plasma PK of Total Radioactivity after Oral Dosing: Apparent Elimination Half-life (t1/2)

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  7. Plasma PK of Total Radioactivity after Oral Dosing: Mean Residence Time (MRT)

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  8. Plasma PK of CORT125281 after Oral Dosing: Cmax

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  9. Plasma PK of CORT125281 after Oral Dosing: tmax

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  10. Plasma PK of CORT125281 after Oral Dosing: AUC0-last

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  11. Plasma PK of CORT125281 after Oral Dosing: t1/2

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  12. Plasma PK of CORT125281 after Oral Dosing: MRT

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  13. Distribution of Total Radioactivity into Red Blood Cells after Oral Dosing

    Measured: Pre-dose and at pre-specified time points up to Day 8 after dosing

  14. Number of CORT125281 Metabolites Accounting for ≥10% of Total Radioactivity Detected in Plasma, Urine, and Feces

    Measured: Until the mass balance criteria for all participants have been met (estimated up to 10 days)

  15. Percentage of Participants with One or More Adverse Events

    Measured: Until the mass balance criteria for all participants have been met (estimated up to 10 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 14C-CORT125281 in people with Healthy, run by Corcept Therapeutics at 1 site in United Kingdom.

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 5 inclusion and 12 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 Mar 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 Kingdom. 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?

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?

Mass Balance Recovery in Excreta After a Single Oral Dose of 14C-CORT125281 (time frame: Until the mass balance criteria for all participants have been met (estimated up to 10 days)). 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 NCT03877952.

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 Mar 2019; AzTrials last refreshed its copy on 8 Nov 2026.
