About this study

Official title: A Phase 1, Open-Label, Single-Sequence Crossover Study in Healthy Subjects to Determine the Effect of Relacorilant on Exposure to Probe Substrates for Cytochrome P450s 3A4, 2C8, 2C9, 2C19, and 2D6

This is an open-label, single-sequence, 3-period crossover study conducted in healthy subjects. Eligible subjects will participate in a single treatment period, in which they will receive the following treatments: Day 1, single doses of midazolam and metoprolol; Day 2, single doses of pioglitazone, tolbutamide, and omeprazole; Days 5 to 17, daily doses of relacorilant; Day 14, single doses of midazolam and metoprolol (with relacorilant); and, Day 15, single doses of pioglitazone, tolbutamide, and omeprazole (with relacorilant).

Read the detailed description

This is an open-label, single-sequence, 3-period crossover study conducted in healthy subjects. Subjects will be screened for eligibility for the study within 21 days before the first dose of study drug based on entrance criteria specified in Section 4. Eligible subjects will participate in a single treatment period, in which they will receive the following treatments:

  • Day 1: single doses of midazolam and metoprolol
  • Day 2: single doses of pioglitazone, tolbutamide, and omeprazole
  • Days 5 to 17: daily doses of relacorilant
  • Day 14: single doses of midazolam and metoprolol (with relacorilant)
  • Day 15: single doses of pioglitazone, tolbutamide, and omeprazole (with relacorilant) Blood samples will be collected before dosing and at intervals up to 24 hours after each midazolam dose, up to 48 hours after each metoprolol, tolbutamide, and omeprazole dose, and up to 72 hours after each pioglitazone dose for assay of the respective probe substrates and relevant metabolites. Additional samples will be collected during the relacorilant dosing period for assay of relacorilant and metabolites to confirm exposure and at the beginning (before dosing on Day 5) and near the end (Day 14) of the relacorilant dosing period for assay for 4β-OH cholesterol, a biomarker for CYP induction.

Safety and tolerability will be monitored using AEs, clinical laboratory evaluations, 12-lead ECG recordings, vital sign and pulse oximetry measurements, 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, 72 hours after the last dose of probe substrate and 24 hours after the last dose of relacorilant. Subjects may leave the CRU after safety review on the morning of Day 18. Each subject will have a follow-up (FU) visit 14 ± 2 days after the last dose of study drug.

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 Day (following a single dose with each probe substrate given within a cocktail of probe substrates) and Test Day (following the same dose given to subjects after 10 or 11 days of daily dosing with relacorilant) areas under plasma concentration-time curve up to the last quantifiable sample (AUC0-tz)

    Measured: predose to 96 hrs postdose

Secondary outcomes (7)
  1. Area under plasma concentration-time curve extrapolated to infinity (AUCinf)

    Ratio of population geometric means (GMR) for Reference Day (following a single dose with each probe substrate given within a cocktail of probe substrates) and Test Day (following the same dose given to subjects after 10 days of daily dosing with relacorilant) areas under plasma concentration-time curve extrapolated to infinity (AUCinf)

    Measured: predose to 96 hrs postdose

  2. Maximum plasma concentration (Cmax)

    Ratio of population geometric means (GMR) for Reference Day (following a single dose with each probe substrate given within a cocktail of probe substrates) and Test Day (following the same dose given to subjects after 10 days of daily dosing with relacorilant) maximum plasma concentration (Cmax).

    Measured: predose to 96 hrs postdose

  3. Adverse Events

    Safety and tolerability measure by number of subjects who experience adverse events

    Measured: up to 8 weeks

  4. Safety Labs

    Safety and tolerability measure by number of subjects who experience potential clinically significant changes in safety labs

    Measured: up to 8 weeks

  5. ECGs

    Safety and tolerability measure by number of subjects who experience potential clinically significant changes in ECGs

    Measured: up to 8 weeks

  6. Vital Signs

    Safety and tolerability measure by number of subjects who experience potential clinically significant changes in vital signs

    Measured: up to 8 weeks

  7. Physical Examinations

    Safety and tolerability measure by number of subjects who experience potential clinically significant changes in physical exams

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Midazolam hydrochloride, Metoprolol tartrate and Pioglitazone hydrochloride 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 22 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 17 May 2018. 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). 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 17 May 2018.
