About this study

Official title: An Open-label Study to Evaluate the Pharmacokinetics, Safety and Tolerability of ABBV-552 in Healthy Adult Japanese and Han Chinese Subjects

This study will assess how safe ABBV-552 is and how ABBV-552 moves through the body of adult healthy Japanese and Han Chinese participants. Adverse Events will be assessed.

ABBV-552 is an investigational drug being developed for potential treatment of Alzheimer's disease (AD). Approximately 18 adult healthy Japanese and Han Chinese volunteers will be enrolled in 2 sites in the United States.

Read more

Japanese participants assigned to Arm 1 will receive ascending doses of ABBV-552 oral capsules once every week for 3 weeks. Han Chinese participants assigned to Arm 2 will receive oral ABBV-552 capsules on Day 1. All participants will be followed for 30 days after their last dose.

Participants will be confined for 22 days or 8 days depending on the Arm they are assigned to. Adverse Events and blood tests will be performed.

    Measured: Up to approximately 21 days

  4. Terminal Phase Elimination Rate Constant (λz) of ABBV-552

    Terminal phase elimination rate constant (λz) of ABBV-552.

    Measured: Up to approximately 21 days

  5. Terminal Phase Elimination Half-Life (t1/2) of ABBV-552

    Terminal phase elimination half-life (t1/2) of ABBV-552.

    Measured: Up to approximately 21 days

  6. Area Under the Plasma Concentration-Time Curve (AUC) From Time Zero to the Last Measurable Concentration (AUCt) of ABBV-552

    AUCt of ABBV-552.

    Measured: Up to approximately 21 days

  7. AUC From Time Zero to Infinite Time (AUCinf) of ABBV-552

    AUCinf of ABBV-552.

    Measured: Up to approximately 21 days

  8. Apparent Oral Clearance (CL/F) of ABBV-552

    Apparent oral clearance (CL/F) of ABBV-552.

    Measured: Up to approximately 21 days

  9. Apparent Volume of Distribution (Vz/F) of ABBV-552

    Apparent volume of distribution (Vz/F) of ABBV-552.

    Measured: Up to approximately 21 days

  10. Dose-Normalized Cmax of ABBV-552 (Arm 1)

    Dose-normalized Cmax of ABBV-552.

    Measured: Up to approximately 21 days

  11. AUC of ABBV-552 (Arm 1)

    AUC of ABBV-552.

    Measured: Up to approximately 21 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ABBV-552 in people with Healthy Volunteers, run by AbbVie 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 3 inclusion and 1 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 6 Apr 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 Adverse Events (AE) (time frame: Up to approximately 45 days). The study lists 11 primary outcomes in all. 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 NCT05686980, which also lists 1 linked publication.

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 6 Apr 2023.
