About this study

Official title: A Phase 1 Single and Multiple Dose Study to Assess the Safety, Pharmacokinetics, and Pharmacodynamics of Baxdrostat in Healthy Japanese and Caucasian Subjects

The goal of this study is to compare the characteristics of baxdrostat (CIN-107) in terms of baxdrostat levels over time in the blood in healthy Japanese and Caucasian volunteer participants.

Read the detailed description

Main Objectives were:

  • To assess the safety and tolerability of single and multiple oral doses of baxdrostat in healthy Japanese subjects.
  • To assess pharmacokinetics (PK) of baxdrostat and CIN-107-M after single and multiple oral doses of baxdrostat in healthy Japanese subjects.
  • To assess pharmacodynamic (PD) effects of single and multiple oral doses of baxdrostat in healthy Japanese subjects.
  • To compare the PK and PD of baxdrostat and CIN-107-M after single and multiple oral doses of baxdrostat between Japanese and Caucasian subjects.

Participants will take baxdrostat and have their safety and blood levels of baxdrostat measured over several days following single and multiple dose administration of 3 different dose levels of baxdrostat. The baxdrostat blood levels over time and the levels of certain hormones that regulate blood pressure will be compared between the dose groups and between the healthy Japanese and Caucasian volunteer participants.

What is being measured

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

  1. Incidence of treatment emergent adverse events following single and multiple doses of baxdrostat in healthy Japanese and Caucasian participants versus placebo recipients.

    Safety and tolerability will be assessed by comparison of number of treatment emergent adverse events between groups.

    Measured: 0 to 19 days after dosing

  2. Area under the curve (AUC) for baxdrostat and the CIN-107-M metabolite after single and multiple oral doses of baxdrostat in healthy Japanese subjects.

    AUC [0 to 24 hours, 0 to last quantifiable concentration, and 0 to infinity of baxdrostat] will be determined for baxdrostat and the CIN-107M metabolite for Japanese participants in each of each of the 3 dose groups of baxdrostat.

    Measured: 0 to 15 days after dosing

  3. Maximum Plasma Concentration [Cmax] of baxdrostat and the CIN-107-M metabolite after single and multiple oral doses of baxdrostat in healthy Japanese subjects.

    Cmax will be determined for baxdrostat and the CIN-107M metabolite for Japanese participants in each of each of the 3 dose groups of baxdrostat.

    Measured: 0 to 15 days after dosing

  4. Plasma aldosterone levels following single and multiple oral doses of baxdrostat in healthy Japanese subjects.

    Plasma aldosterone levels will be determined for baxdrostat and the CIN-107M metabolite for Japanese participants in each of each of the 3 dose groups of baxdrostat.

    Measured: 0 to 15 days after dosing

  5. Time to Maximum Plasma Concentration [Tmax] of baxdrostat and the CIN-107-M metabolite after single and multiple oral doses of baxdrostat in healthy Japanese subjects.

    Tmax will be determined for baxdrostat and the CIN-107M metabolite for Japanese participants in each of each of the 3 dose groups of baxdrostat.

    Measured: 0 to 15 days after dosing

  6. Terminal elimination half-life of baxdrostat and the CIN-107-M metabolite after single and multiple oral doses of baxdrostat in healthy Japanese subjects.

    Terminal elimination half-life will be determined for baxdrostat and the CIN-107M metabolite for Japanese participants in each of each of the 3 dose groups of baxdrostat.

    Measured: 0 to 15 days after dosing

Model description
This was a single and multiple oral dose study of the safety/tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) in healthy Japanese subjects compared with a cohort of healthy Caucasian subjects. total of 41 subjects were enrolled in this study: 31 Japanese subjects and 10 Caucasian subjects. The study included 4 cohorts and each cohort consisted of 10 subjects, randomized 4:1 (active:placebo). The Japanese cohorts (Cohorts 1, 2, and 4) were performed in parallel. The Caucasian cohort (Cohort 3) was performed after Cohort 2 was complete so that the Caucasian subjects could be matched by certain demographic factors.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing baxdrostat in people with Hypertension, run by AstraZeneca 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 33 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 14 Aug 2023. 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?

Incidence of treatment emergent adverse events following single and multiple doses of baxdrostat in healthy Japanese and Caucasian participants versus placebo recipients. (time frame: 0 to 19 days after dosing). The study lists 6 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 14 Aug 2023.
