About this study

Official title: A Phase 1, Open-Label, Single-Sequence Crossover Study in Healthy Subjects to Determine the Effect of an Inhibitor of Cytochrome P450 3A on Exposure to Relacorilant and Its Main Metabolites

This is an open label, single sequence, crossover study. In Part 1, eligible subjects will participate in 3 treatment periods, in which they will receive the following treatments in turn: 1) In Period 1, a single 350-mg dose of relacorilant administered alone, 2) In Period 2, once daily 200-mg doses of itraconazole administered for 3 days; 3) In Period 3, single 350-mg dose of relacorilant administered with a concomitant 200-mg dose of itraconazole and continued once daily 200-mg doses of itraconazole for three additional days.

If Part 2 is conducted, eligible subjects will participate in 2 treatment periods, in which they will receive the following treatments in turn: 1) In Period A, once daily 300-mg doses of relacorilant alone for 10 days; 2) In Period B, once daily 300-mg doses of relacorilant in combination with once daily 200-mg doses of itraconazole for 10 days.

Read the detailed description

This is an open label, single sequence, crossover study. In Part 1, eligible subjects will participate in 3 treatment periods, in which they will receive the following treatments in turn: 1) In Period 1, a single 350-mg dose of relacorilant administered alone, 2) In Period 2, once daily 200-mg doses of itraconazole administered for 3 days; 3) In Period 3, single 350-mg dose of relacorilant administered with a concomitant 200-mg dose of itraconazole and continued once daily 200-mg doses of itraconazole for three additional days.

Part 2 of the study may be conducted if the results of Part 1 indicate that itraconazole has a clinically meaningful effect on exposure to relacorilant and metabolites. If Part 2 is conducted, eligible subjects will participate in 2 treatment periods, in which they will receive the following treatments in turn: 1) In Period A, once daily 300-mg doses of relacorilant alone for 10 days; 2) In Period B, once daily 300-mg doses of relacorilant in combination with once daily 200-mg doses of itraconazole for 10 days.

Blood samples will be collected before dosing and at intervals up to 96 hours after relacorilant dose in Part 1, and up to 24 hours after the last dose of relacorilant in each study period in Part 2. In Part 1 only, additional samples will be collected during the itraconazole dosing to confirm exposure.

Safety and tolerability will be monitored using AEs, clinical laboratory evaluations, 12-lead ECG recordings, vital signs, and and physical examinations.

Subjects will be admitted to the Clinical Research Unit (CRU) on the morning of Day -1 following an 8-hour fast for baseline assessments and will remain confined until completion of procedures. Each subject will have a follow-up (FU) visit 14 ± 2 days (Part 1) or 7 ± 2 days (Part 2) after the last dose of relacorilant.

What is being measured

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

  1. Area under plasma concentration-time curve up to the last quantifiable sample (AUC0-tz)

    Ratio of population geometric means (GMR) for Reference (following oral administration of relacorilant alone) and Test (following the same dose given to subjects concomitantly with itraconazole) areas under plasma concentration-time curve up to the last quantifiable sample (AUC0-tz)

    Measured: predose to 96 hrs postdose in Part 1 and predose to 24 hrs after last dose in Part 2

Secondary outcomes (3)
  1. Area under plasma concentration-time curve extrapolated to infinity (AUCinf)

    Ratio of population geometric means (GMR) for Reference (following oral administration of relacorilant alone) and Test (following the same dose given to subjects concomitantly with itraconazole) areas under plasma concentration-time curve extrapolated to infinity (AUCinf)

    Measured: predose to 96 hrs postdose in Part 1; AUCinf not calculated in Part 2 due to steady state evaluation

  2. Maximum plasma concentration (Cmax)

    Ratio of population geometric means (GMR) for Reference (following oral administration of relacorilant alone) and Test (following the same dose given to subjects concomitantly with itraconazole) maximum plasma concentration (Cmax).

    Measured: predose to 96 hrs postdose in Part 1 and predose to 24 hrs after last dose in Part 2

  3. Number and Severity of Treatment Emergent Adverse Events

    Treatment Emergent Adverse Events will be summarized overall and by treatment based on their frequency and severity of treatment emergent adverse events

    Measured: up to 7 weeks in Part 1 and up to 7 weeks in Part 2

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Relacorilant 350mg, Itraconazole and Relacorilant 300mg in people with Healthy, run by Corcept Therapeutics 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 9 inclusion and 20 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 24 Mar 2020. 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?

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?

Area under plasma concentration-time curve up to the last quantifiable sample (AUC0-tz) (time frame: predose to 96 hrs postdose in Part 1 and predose to 24 hrs after last dose in Part 2). 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 24 Mar 2020.
