About this study

Official title: A Phase I Randomized Single-blind Placebo-controlled Study to Assess the Safety, Tolerability, and Pharmacokinetics of AZD6234 Following Single Ascending Dose Administration to Healthy Subjects Who Are Overweight or Obese

A study in healthy male and female participants of non-childbearing potential who are overweight or obese.

Read the detailed description

The study will comprise of:

  • A Screening Period of maximum 28 days.
  • A Treatment Period during which participants will be resident at the Clinical Unit from three days before (Day -3 ) Investigational Medicinal Product (IMP) administration (Day 1) until at least 4 days (96 hours) after IMP administration, participants will then be discharged on the morning of Day 5.
  • Weekly outpatient visits on Days 8, 15, 22, 29, and 36 for blood sample collection, Electrocardiogram (ECGs), and adverse events (AE) recording.
  • A Follow-up Visit 6 weeks (Day 43) after the last IMP dose.

Furthermore, 3 dose levels of AZD6234 for Subcutaneous (SC) administration (Cohorts 1 to 3) and one dose level for Intravenous (IV) administration (Cohort 4) are planned to be investigated in healthy participants who are overweight or obese. The IV cohort (Cohort 4) can begin in parallel or after Cohort 3. One dose level for SC administration is planned to be investigated in Japanese participants only (Cohort 5), and up to 3 additional dose levels for SC administration are planned to be investigated in healthy participants (Cohort 6 to 8). Depending on the findings, additional (optional) dose level cohorts may be added at the discretion of the Sponsor.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AZD6234 and Acetaminophen in people with Healthy Participants, run by AstraZeneca at 2 sites 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 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 26 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Number of participants with AEs and Serious Adverse Events(SAE) (time frame: From Screening until Follow up (Day 43)). 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 26 Dec 2023.
